Understanding the genetic predisposition to myocardial infarctions Gene is linked to heart attacks
While preliminary data, this research suggests that our thoughts about a cardiac inflammatory response make sense. As we better understand this response, and associated factors, so might we better screen and prevent coronary artery disease manifestations.
Do statins decrease post-surgical mortality Surgery carries many risks. One is the risk of inducing a cardiac event (probable stimulated by stress). We know that beta blockers decrease the risk of post-surgical mortality (especially in patients at high risk for coronary artery disease). Now we have epidemiologic data suggesting that statins may also offer some protection. Lipid-Lowering Therapy May Reduce Mortality After Major Surgery
Thus, we have interesting data founded in solid theory. But, as the investigator cautions, we still need a prospective study prior to widespread adoption of this new strategy. Posted byNail and hammer I always wondered where this quote originated. "If the only tool you have is a hammer, you tend to see every problem as a nail." -- Abraham Maslow (1908-70), American psychologist, founder humanistic psychology We generalists often use this quotation to describe subspecialty behavior. Sometimes we are right! Rethinking cardiac risk factors Many patients who develop coronary artery disease have well known major risk factors. These include smoking, family history, high LDL cholesterol, diabetes mellitus, low HDL and hypertension. However, these risk factors do not explain all coronary artery disease. Recent research has expanded our ideas about etiology and risk. This Washington Post article does a nice job summarizing our emerging understanding of risk factors. Not Your Father's Heart Attack
I recommend this article as a nice summary of an important topic. Posted byCreatine - apparently safe With all the furor over anabolic steroids and ephedrine, creatine remains the leading supplement for weight training. I hesitate to label creatine a supplement, but it actually fits the title very well. We all make creatine naturally. Extra creatine (whether dietary or in supplementation) seems to allow weight lifters to lift heavier weights. This leads to increased muscle growth, because the creatine allows the athlete to handle increased loads - leading to more growth. Numerous studies show creatine safe and effective. This article summarizes the data well - The creatine edge I have chosen to not take creatine myself, because I do not see a reason to supplement my muscle growth. I cannot criticize those who use it, as this supplement does have good safety data. However, like all supplements, bioavailability and consistent dosing are problematic - because the industry is not well regulated. Posted byViewing fat through historical and cultural eys Demonizing Fat in the War on Weight
A great example of this "movement" - The big fat con story
His book - The Obesity Myth - represents his treatise on this issue. The article summarizes his argument. Several important points need addressing. We can ignore the argument about BMI. Yes, many healthy athletes have elevated BMI. We should focus our definition more on fat percentage or waist circumference. Second, when we do that, we find that as fat increases, so does the risk of type II diabetes mellitus (and therefore atherosclerotic complications) and obstructive sleep apnea. Anyone you makes rounds with me for a month would see the devastation that those disease cause. Physicians are not making a moral argument, rather we are focusing on prevention. When we have patients exercise and lose fat, their outcomes improve. Admittedly, we need a new method to achieve that goal. Posted byOn vaccination Recently, a reader wrote to ask if I allowed "guest rants". The reader wanted to rant against vaccinations. I do not allow guest rants, this page is my ranting place. You can comment, but I chose the rants. I had not thought much about the request until I came across this article - Anti-Vaccination Fever. The author relates the story of pertussis (whooping cough) and how the anti-vaccination lobby has allowed this disease to make a comeback.
Read this fascinating, albeit technical, exposition. Posted byAn important surgical study Too often, new surgical techniques do not receive a careful analysis. The VA came through to answer an important question - what is the best approach to hernia repair - Open Mesh Better Than Laparoscopic Mesh Inguinal Herniorrhaphy
Surgical studies are always difficult. This study does remind us that we can not randomize surgical skill. Some surgeons obtain better results than others. The wise generalist figures out which surgeons to whom he/she should refer. If patients need major surgery, they should try to find outcomes if at all possible. At least use a surgeon with significant experience doing that procedure. Posted byAnd we all know these patients? Answer, but No Cure, for a Social Disorder That Isolates Many Posted byGeneral internal medicine - the domain Task Force Redefines the Domain of General Internal Medicine
I had the opportunity to read and comment on this report during its construction. Like any such report I can find areas which I dislike. On balance though, SGIM has taken an important initiative to address the important question of how to reinvigorate general internal medicine. A careful reading will reveal many issues that we discuss in this blog. I always try to take such reports in context of the old Southern saying: "If it ain't broke, don't fix it!" Well, generalist care is broken, and thus requires remedies. I certainly hope that this report focuses the debate. We need a healthy discussion to develop more functional solutions to generalism. Posted byA case to read for your medical enjoyment I like this case a great deal. Read it carefully, and see how quickly you can make the diagnosis. Tunnel Vision, Cramped Hands, Nausea Posted byStatins for diabetes As we discuss type II diabetic patients, we generally assume that they have coronary artery disease unless we have proven that they do not. Atherosclerotic complications occur very frequently in patients having type II diabetes. Current guidelines also make this assumption. Now we have a strong recommendation concerning statins in these patients. Treatments: Statins and Diabetes: New Advice
I believe that this guideline makes sense in lieu of the mounting data. Posted byThey are right, but ... Amazing! I just ranted about this issue yesterday. This article bemoans our expenditures on hypertension management - Following Evidence-Based Hypertension Guidelines Could Save Billions. Great! We can do a better job! As they say on the Guiness commercial (I only wish that I could get some royalties here) - BRILLIANT! . Quit bemoaning, and develop strategies to fix the problem. Identifying the problem is not enough. These researchers (who are excellent and well regarded) must address solutions. If they do that, then it really will be BRILLIANT! . Posted byThe challenge and importance of being a generalist I love General Internal Medicine - both outpatient and inpatient. The intellectual and patient interaction challenges never diminish. We must maintain broad knowledge and develop the skills to apply that knowledge to our patients. Unfortunately, most physicians can improve their performance. However, I am often frustrated by the repeated complaints about generalist performance. Here are the two most recent examples: CDC: Fewer doctors urge weight loss and Statins Underused in High-Risk Elderly Patients These two examples represent an entire class of such articles. What do these articles tell us? How should we interpret the articles? What should we (the medical community) do with this information? Using the medical paradigm, one should seek more than making a diagnosis. One should consider the possibilities of treatment. Moreover, we should not stop at making a diagnosis. We must understand what causes the problem. Consider outpatient medical practice. Each day we see multiple patients with multiple medical problems. Each patient requires attention to a variety of medical problems, including the interaction of those problems. In addition to those problems, we must consider a variety of preventive measures. Careful consideration of all issues might take as long as 30-40 minutes for some patients. But our current reimbursement system dictates shorter visits. Our current reimbursement system dictates seeing too many patients. Any interest group (and yes the CDC report on obesity represents an interest group) can seek and find deficiencies. However, I do not see much work on helping diagnose and treat the problem. We focus on symptoms, but do not understand the disease. Thus, I decry these articles. They are no longer constructive, rather they are destructive. We need a new attitude amongst the health services research community. Quit looking for deficiencies, rather focus on diagnosing and improving health care provision. We need constructive approaches to outpatient and inpatient care. We need to improve. If I am slicing my drives, I go to my golf pro to diagnose why, and then work on techniques to improve my drives. If the pro just tells my that I have a lousy swing, but does not teach me how to improve, I would likely look for another pro (I say likely, because some golfers are not willing to really try to improve). Our research group has a committment to understanding medical practice and the barriers to meeting guidelines. We hope to find solutions. I believe that rather than moan about errors and deficiencies, we should champion successes. We can learn more from the positives than the negatives. Physicians will strive towards excellence. Show us how! Posted byMaking oral narcotics non-abusable Physicians are damned if we underprescribe narcotics to pain patients, and damned if we prescribe to those who abuse drugs. Some pharmaceutical companies are trying to make oral narcotics effective, yet not abusable. Drug Makers Hope to Kill the Kick in Pain Relief
So we may soon see effective oral pain control without the option of using the pills in alternate ways. This is good news for pain control. We need the ability to prescribe without worrying about the possibility that we are contributing to drug abuse. These pills will help those patients who really need pain relief. Posted byCan primary care survive?
So one can certainly lay some blame on the insurance companies for perverting the primary care concept. However, we must take blame ourselves. We did not think through the "unintended consequences" of the gatekeeper model. Can we save primary care? Should we save primary care? I believe that the answer to both questions is yes. Patients need generalist physicians. We need physicians who care for the entire patient. I suspect that most of our patients understand this. Several movements bode well. Retainer medicine speaks to the concept loudly. While some argue that retainer medicine is just a money ploy, I would argue that some patients are willing to pay to have one intelligent caring physician available, knowledgeable and capable. Similarly, the cash only practice movement shows that patients will pay for good service. Thus, I expect primary care to transform (albeit slowly and begrudgingly). The change will take time, because few adults embrace change. But the change will help our health care.

I guess this judge is not impressed with sophistry. Posted byWhy paternalism does not die Ordering Treatments à la Carte
Paternalism is not dead. Nor should we kill it. Perhaps we should develop a new category, patient directed paternalism! Posted byGood news from Medicare Medicare Web Site to Provide Comparative Data on Prescription Medicines Posted byChallenges with the ACGME work guidelines Residencies pinpoint work-hour hurdles
Those who have not gone through residencies (non-physicians) have a difficult time understanding the difficulties that these new regulations bring. The regulations conflict with long traditions. I still do not understand how and why new, seemingly arbitrary regulations were adopted without testing. Perhaps residencies will improve. Perhaps our trainees will become better doctors. But we do not know what the long term effect of these rules. We continue to work to improve our residency while meeting the regulations. We hope for positive results. Posted byA Medicare alert on concierge practice Alert warns of Medicare conflict for concierge practices Those who start concierge practices (I prefer the term retainer practice) must carefully examine Medicare billing rules. One can still bill Medicare, however, one must be very careful not to claim that the retainer fee covers any service for which the provider also bills Medicare. Posted byNot a free market Our buddy Trent McBride has stirred up a great controversy. So When Are We Going To Get That Free-Market Health Care Everyone's Complaining About? . If you find that interesting, he has 2 follow-up posts. His rant explains (and I agree here) that we do not have a free market health care system. We have an almost nationalized health care system. Government payments and regulations prevent any free market influence (in general). He has created quite a stir in the blogosphere. I believe that this stir shows a general misunderstanding of medical practice. The biggest influence on medical reimbursement is Medicare (unless you do pediatrics). When they develop reimbursement, the insurers quickly follow. When they develop regulations, physicians pay. He rightly comments on various governmental regulations which increase overhead without allowing a way to recoup those costs. Government (i.e., Congress) influences physicians and hospitals in ways which negate any free market forces. Medicine has some exceptions - cash payments for some plastic surgeries, cosmetic dermatology, etc. However, generally, we work in a highly regulated environment. Kudos to the Proximal Tubule for starting the debate. We here at the Countercurrent Mechanism applaud his efforts. Posted byRaising HDL Test Drug Said to Increase Good Cholesterol and Torcetrapib Significantly Increases HDL Cholesterol Levels. Epidemiologic data indicate that low HDL cholesterol levels put patients at a significant risk for atherosclerotic complications - coronary artery disease, stroke, peripheral vascular disease. We assume that raising the HDL would therefore decrease the risk of these conditions. Until now, the only drug which consistently raised HDL was niacin. A new study shows that (at least under experimental conditions) one can increase HDL with a new drug.
Remember that this drug is still experimental. We must wait to learn two major things. First, how safe is this drug when taken over time. Second, does this drug improve patient outcomes. One must always take these preliminary articles as just that - preliminary. The concept has promise. Now we must wait a few years until the appropriate studies are done. Posted byThe match I have received a few important comments about the match. The wife of an incoming intern wrote:
First, please read very carefully Save the Match. Second, imagine the world without a match. Who would suffer? I proposed this question to some residents while supervising in clinic a couple of days ago. To paraphrase one, "obviously the critics have not participated in a non-match fellowship search". She shared with me her initial concerns about the match as a 4th year student. However, having just finished the interviews and acceptance of a non-match fellowship, she lamented the lack of a match in her fellowship! The match uses the game theory which John Nash (he of a Beautiful Mind) developed. The current algorithm helps students get the highest choice which has an opening for them. It is student biased rather than hospital biased (go to the web site for links to the studies). The match does not drive wages, or working conditions. Medicare reimbursement drives wages. ACGME and residency review committees drive working conditions. Working conditions have improved dramatically since I graduated in 1975. I see excellent progress regularly. I could develop a thought experiment in which working conditions might worsen at some highly desirable residencies! However, the working conditions depend more on regulatory bodies, and how the students "vote" during their match. Programs which treat their residents better tend to have better matches. The anarchy of life without a match would (according to the web site) disadvantage couples (over 500 couples matched last year) and minorities. This protest and lawsuit are (in my opinion) poorly considered. Few would benefit from the unintended but predictable consequences of the lawsuit's success. Posted byMore on the match A Job or More School? Young Doctors Take On 'The Match'
So why have a match? Why not have a free market for residencies? We believe (the great majority of attendings and residents) that the match protects both applicants and programs. It allows us to go through a careful process of evaluating the many applicants to our programs and choose interns/residents in a standard way. What would happen if we had no match? (my speculation follows)
If the courts rule against the current situation, we will have increased chaos. I would suspect that most students would then ask for a match. I am certain that most programs would. This suit might sound good to some who are not part of residency training. The destructiveness of this suit's possible success scares me greatly. Posted byCash on the barrel Most outpatient physicians hate insurance companies (including Medicare). Their pay scales are insulting, and the necessary overhead makes seeing patients minimally profitable. Some physicians have decided to go "old school" and eliminate the insurance companies. Some Doctors Choosing Cash Over Insurance
Cash visits make great sense for patients and physicians.
I love ideas that make sense. Read more about this movement - SimpleCare. This movement runs parallel to the retainer medicine movement. Both movements are suceeding due to patient and physician dissatisfaction with insurance and outpatient medicine. I would still advocate for "big ticket item" insurance. But perhaps this simple concept should become the norm. Posted byA new weight loss operation (or rather two) Double surgery for obese 'safer'
Interesting, but one must wonder about the side effects of the intestinal bypass. But then drastic situations sometimes require drastic solutions. Posted byUnderstanding the effects of leptin Animal research is starting to suggest some clues as to why weight loss is so difficult. Studies on a Mouse Hormone Bear on Fatness in Humans
Very interesting stuff, which may eventually help us better understand weight control. Posted byMaybe my last post on paternalism and prescription drugs I have read the comments. I have reconsidered the radical libertarian stand. As I absorb the hyperbole, sophistry and especially obfuscation which my debating opponents utilize, I will try to return to first principles. Primum, non nocere. - First, do no harm. In this context, I believe that many medications, if sold over the counter, could do great harm. I am also certain that improper dosing and improper combinations of medications can do great harm. Of course, we have pharmacists to help us prevent dangerous drug interactions - but would the libertarian position end the licensing of pharmacists. Why not sell HIV meds at the grocery store? As I read the arguments for ending FDA controls and required physician prescribing, I see many straw men. I do not believe that one can extrapolate from many of the examples. But I will use this retort? Should the government require a licensed engineering firm to design a bridge? Why not just let the construction company build the bridge from their experience? Many drugs can reasonably make the transition to OTC. Many do. We better make those decisions once we have enough experience to know the safety profile of the drug. Many prescription drugs do cause problems, and are removed from the market. We certainly can (and should) loosen restrictions on some drug classes. Other drug classes and diseases should require medical care and decision making. I do not worry about the compulsive intelligent consumer who might research his/her problem extensively and do self-dosing (although I have seen physicians cause harm to themselves with self prescribing). Those patients will at least think through the pros and cons of treating themselves (perhaps). I worry about the many patients who get advice from friends - oh, you must have CHF - try an ACE inhibitor - it worked for me. Remember Primum non nocere should guide us. Following the radical libertarian approach would do harm to many, some of whom cannot understand the risks. Posted byThe link between alcohol and nicotine We all really know this. Talk to any smoker, and he/she will tell you that they always drink more in a bar. The physiology makes sense. Habits: A Smoke Much Sweeter
If researchers can better decipher this interaction, we might gain some treatment ideas. It does explain an interesting phenomenon, and provide some useful information for counseling patients. Posted byPhysicians, prescription drugs and a libertarian philosophy As one commenter suggested, I have really enjoyed the comments on my paternalism rants. They have help inform my conceptualization about this subject. If one takes a libertarian viewpoint in our society one must still understand that the limits of ones freedom end when another is harmed. The common shorthand expression - The freedom of your fist ends just short of my nose. So the first test for restricting a medication must involve potential costs to society of improper use. Certainly all antimicrobials fit into that paradigm. The huge problem of MDR-TB (multidrug resistant tuberculosis) stems from unrestricted access and distribution of TB drugs. You may want to take your medications as you choose (or even think you have researched). However, your knowledge lack can lead to my worse illness. In fact, we take a very paternalistic view of TB in this country requiring DOT (directly observed therapy) give through public health departments. One can certainly extend this concept to all antimicrobials - the good of many others should outweigh your desire to buy antibiotics without seeing a physician. Admittedly, the philosophical position gets more complex when discussing cardiac medications. However, your illness improperly treated (because you chose your meds rather than having a trained physician choose those meds) costs society significant dollars - from hospitalizations, lost productivity, etc. That decision also has a significant impact on your loved ones. Critics argue against licensing physicians and requiring proper training. I have a difficult time understanding that position. Medical care has advanced dramatically over the past 50 years. This care advances because of our training and research. We do need standards for the public good. You can choose care from a non-physician - e.g. chiropractic care. That certainly gives you freedom. You can go to a health food store and self treat with supplements and herbs. That gives you freedom. In my opinion that also gives you substandard care. Like many such arguments, one can take a highly controversial position and incite everyone. However, as I read the comments, that highly controversial position does not withstand careful scrutiny for our society. Our current medical system is not perfect, but it is very good. We do improve the quality of lives. We do lengthen life spans. We cure many infections. I cannot believe that a call for anarchy will help society. Thus, your freedom to buy any medication that you desire without medical consultation could lead to societal harm. And that should be the main concern. Posted byMore on Paternalism EKR at Educated Guesswork writes about my paternalism rant - When is paternalism justified?
Let me try again. Many patients make their own decisions regardless of our recommendations (and remember, we prescribe we do not force feed medications). I guess a well educated patient might be able to figure out a complex medication regimen. But it really is unlikely. I guess I could treat myself - but we do have a saying about that - "The doctor who treats himself has a fool for patient". So I must endorse this form of paternalism. Physicians have the training and experience to juggle the multiple conditions and disease manifestations. We should include the patient in our decision making - but we should recommend and recommend strongly a treatment course that best fits the available evidence. For that I do not apologize! Posted byThe Proximal Tubule on Paternalism in Medicine Paternalism In Medicine - Part II: Gatekeepers Trent McBride writes a long rant about the influence of prescription drugs on the doctor patient relationship. First, I love the blog's title - I love renal physiology. Maybe I should rename my blog the Countercurrent Mechanism. Or that could be a great name for an alternative band! Trent hypothesizes that making patients come to the doctor for prescriptions represents the ultimate form of paternalism. I will disagree to some extent on his proposed solutions. Yes, prescribing medications is paternalistic. But then I do not assume that all medical paternalism is bad. If you have congestive heart failure, I have a complex drug regimen to prescribe. Adjusting these medications requires repeated visits. I must understand the side-effects of each medicine, alone and in combination. I must consider your renal function, and your electrolytes. Finally, I must prescribe the medications with an understanding of your other medical problems (and few patients have CHF alone). So to provide the highest quality care, I believe that I must be paternalistic. In that sense paternalism is not a bad attribute. Narcotics might be the exception. I do not really know how much pain a patient suffers. How can I judge the best method for treating that pain? Should I worry about narcotic abuse? Wouldn't we be better off if we just let patients buy their own pain meds and suffer their own consequences? Trent does mention antibiotics - and he is correct. But I will gladly argue that many conditions which I treat require complex decision making and adjusting of multiple medications. I accept that paternalism and I believe the great majority (>90%) of patients want that paternalism. Caveat ahead - even when one must take a paternalistic stance, one should still discuss the rationale for each medication with the interested patient. When choices are available for treatment, we can and should discuss those choices with the patient. So as usual, I am a bit wishy washy. I agree with some of the Tubule's argument. But I believe he goes overboard. But after all, that is what blogs are for - to stimulate our thinking and challenge accepted thinking. And therefore he succeeds. Posted byOn hypochondria (or somatization disorder) A New Era in Treating Imaginary Ills
If these patients do not induce "heart sink" then you are a different physician than me. These patient's name on your daily list causes anxiety, depression and thoughts of illness. The biggest challenge is sorting out their hypochondriacal complaints from real disease, because even a hypochondriac can get sick. I once had a patient who came to me after having 17 negative HIV tests. He had not had any sexual relations in over 6 months, yet thought he needed another test. I saw this patient for around 9 months. My greatest feat was getting him back to see his psychiatrist, as he also had major depression. Over time with reassurance, calm, scheduled appoints and medication he was able to regain a productive life. As I read the article this morning, I saw most of his personality and problems. We (physicians) would all like a consultant who wanted to see these patients, as most physicians and psychiatrists shun them. I certainly hope that these initial positive reports are confirmed. Posted byNY Times comments on coronary artery disease The Limits of Opening Arteries
What follows represents the implications of this essay and the accumulated data that I teach on rounds. I have tried to interpret the original data and read about the theories. Procedures - CABG and stenting - are still very important in 2 scenarios. First, patients who have just had an acute coronary syndrome, especially a small heart attack (which we call either NSTEMI or non-Q wave MI), clearly benefit from immediate intervention. Second, patients who have extensive disease (usually 2 or 3 vessels with severe narrowing) and problematic symptoms have their symptoms improved with interventions. Choosing an intervention must take into account the lesions, their location and availability of good artery past the obstruction. One must also consider current cardiac function (e.g., 3 vessel disease with a decreased ejection fraction has better results from surgery). One should not go looking for disease to "repair" in asymptomatic patients. One might want to diagnose disease in patients with mild or equivocal symptoms - but not to "repair" the disease. Regardless of whether patients do need a procedure, they need good medical management. I have written often about this issue. To reiterate: We clearly know that coronary artery disease patients benefit from 4 drug classes
So the article and this editorial describe the current thinking of coronary artery plaques as fragile changing lesions. Understanding the dynamic nature of plaques gives us a broader understanding. This concept explains much current clinical trial and epidemiologic data. It drives current therapy. Most important it should give hope to patients. As patients we can take some responsibility for our hearts. Exercise, weight control, and - when indicated - medications can modify coronary artery plaques, leading to regression and stabilization. Patients can often prevent coronary artery disease, but when they cannot (bad genetics especially), physicians can help greatly by prescribing the right drugs. Of course, the responsibility quickly reverts to the patient who then must take those medications. Posted byOn listening to tape about Nietzsche and considering yesterday's rant Listening to philosophy tapes certainly gives me a different perspective on medicine. Currently I am listening to Will to Power: The Philosophy of Friedrich Nietzsche. This morning on the way to working out and then to work I was lietening in particular to: Lecture 11: Nietzsche on Truth and Interpretation. This lecture expands on the quote you see on the right of this blog: There are no facts, only interpretations. - Nietzsche . As the lecturer expands on this discussion, I started to understand why yesterday's rant created such interest (8 comments by this morning). As I personally rate my rants, the number of comments provides me a good indicator of their effectiveness in stimulating thinking and interest. Reading the comments, and then rereading Sydney's column, I realize that I am working from a different context. Nietzsche would argue (or at least the lecturer is arguing for him) that we only have interpretation in our attempts at truth. All interpretations depend on the context in which one views the data. Our friend and frequent poster Bernie lives in a different contextual framework than I do. Thus, he views the same data but interprets it differently. Now unlike many politically correctness advocates today, Nietzsche does not assume that all viewpoints have equal value (of course, he is judging from his own context). I believe that the bio-medical model is the superior model for judging medical data. (Bernie might disagree - but then I should not speak for Bernie). As I read Sydney's column, she alludes to an important point. We must take all new data and put those data into our underlying context. What do we already know? Can we reconcile these new data with previous data? I believe that the best way to interpret new data uses the principles of evidence based medicine. One should not discount |
