Doctors Halt Squabbling And Agree How To Manage Hypertension In People With Blocked Arteries Reply

There’s been a lot of drama in the hypertension field over the past few years. Initially sparked by the decision of the National Institutes of Health to end its sponsorship of national guidelines, the subsequent appearance of multiple guidelines with divergent recommendations led to even more controversy and discussion. Now, however, the appearance of a new scientific statement may indicate that some of the drama is dissipating, at least in one important subset of the field.

The scientific statement from the American Heart Association, the American College of Cardiology, and the American Society of Hypertension covers the important area of the treatment of hypertension in patients with existing coronary artery disease.

More Guideline Controversy: The Tricky Business Of Calculating Cardiovascular Risk Reply

Calculating cardiovascular risk has become a central and highly controversial component of cardiovascular guidelines. Now a study in the Annals of Internal Medicine finds that most of the commonly employed tools seriously overestimate the risk of people today.

Very Simple High-Fiber Diet Stands Up To American Heart Association Diet Reply

Diets notoriously fail to help people lose a lot of weight. One problem is that most diets include a broad range of restrictions and guidelines that many people find difficult to follow. Another problem is that negative recommendations may have unintended consequences, such as low-fat recommendations leading to increased consumption of refined carbohydrates. Now a new study published in the Annals of Internal Medicine indicates that a radically simple diet containing only one positive rule — eat more fiber — might be nearly as effective and much easier to swallow than a more traditional complex diet.

Salt, Science, And The American Heart Association’s Double Standard Reply

Once again the American Heart Association is sticking by its recommendation that pretty much everyone should consume no more than 1,500 milligrams of sodium each day. This is dramatically lower than the 3,500 mg/d the average American now consumes. In a blog post reprinted on MedPage Today the president of the American Heart Association,  Elliott Antman, assails a study published earlier this week which found no benefits– and even a hint of harm–  for elderly people with low sodium consumption.

But Antman only tells one side of the story.

An Expert’s Perspective: Why Salt Is Not Like Tobacco And Why Guidelines Are Tricky Reply

At the center of this week’s renewed debate on salt was Salim Yusuf, the long influential and often controversial cardiology researcher and clinical trialist based at McMaster University in Hamilton, Ontario. I spoke with Yusuf before the publication of the New England Journal of Medicine papers, which include his own two papers from the PURE study.

Yusuf was troubled by the tone of the salt debate. He’s no stranger to scientific controversies and intense disagreement, but “scientific criticism is one thing, personal attack is another,” he said. Because he has presented data that suggests that moderately high levels of sodium may not be as bad as some had thought, and that very low levels of sodium may actually be harmful, “we’ve come under huge attack.”

More Guideline Controversy: Blood Pressure Expert Decries ‘Political Correctness’ Reply

Now add “political correctness” to the long list of criticisms directed against the recent publication of new and updated cardiovascular guidelines. One leading hypertension expert writes that the authors of the recent AHA/ACC/CDC Science Advisory on blood pressure control were chosen not for their expertise but for political expediency.

Missing High Blood Pressure Guideline Turns Up In JAMA Reply

After  years of delay and many twists and turns, the hypertension guideline originally commissioned by the NIH has now finally been published in JAMA. The evidence-based document contains a major revision of hypertension treatment targets and includes new and somewhat simplified recommendations for drug treatment.

The previous US hypertension guideline was published more than a decade ago. After many delays the new guideline was ready for publication earlier this year, but then the NIH decided to get out of the guidelines business. The American Heart Association and the American College of Cardiology assumed responsibility for the development and publication of cardiovascular guidelines and last month published four new cardiovascular guidelines, with the notable exception of the hypertension guideline. As an accompanying JAMA editorial explains:  “Rather than go through an additional review process with the AHA and the ACC the authors decided to publish their guideline in JAMA on their own.”

The big headline of the new guideline is an important change in treatment targets.

Slouching Toward Phase 3: Progress Report On New Cholesterol Drugs At The AHA Reply

The American Heart Association meeting in Dallas this year brought new phase 2 data about several promising new cholesterol drugs. But before jumping on any bandwagons it would be good to remember that even for the drugs most far along in development we still haven’t seen any phase 3 data. In addition, it bears repeating that the FDA may well be raising the entry bar for new cholesterol medications. As I wrote not too long ago, there is a good chance that the FDA will require completed outcomes studies for new cholesterol drugs. There’s good reason to be interested in these drugs but any predictions at this point would be hopelessly speculative.

TACT Substudy Suggests Possible Strong Benefit for Chelation in Diabetics Reply

One year ago the results of the TACT trial were published in JAMA, sparking an enormous controversy over the propriety of publishing a trial suggesting that chelation therapy might be beneficial in people with cardiovascular disease. Chelation therapy has long been a staple of alternative medicine, but until the publication of TACT it had received no credit whatsoever in mainstream medicine. TACT was supported by the NIH as part of an initiaitve to test the scientific basis of alternative medical therapies.

The JAMA paper reported positive results for the prespecified subgroup of patients who had diabetes at the start of the trial. Now a new paper, presented at the American Heart Association Scientific Sessions and published online in Circulation: Cardiovascular Quality and Outcomes, focuses on this important subgroup, and provides even stronger evidence for a possible benefit for chelation in patients with diabetes. The authors speculate that ethylene diamine tetra-acetic acid (EDTA) chelation might have an effect on metal-catalyzed oxidation reactions in the development of advanced glycation end-products, which appear to play a central role in diabetic complications.

The primary endpoint of the main trial – the composite of death, MI, stroke, coronary revascularization, or hospitalization for angina – was significantly lowered from 30% in the placebo group to 26% in the chelation group (HR 0.82, 0.69-0.99, p=0.035).

No Value For Renal-Artery Stenting In CORAL Reply

Previous small studies have failed to find any benefit associated with renal-artery stenting, but the trials have been small and were not powered for clinical outcomes. Now, the CORAL (Cardiovascular Outcomes in Renal Atherosclerotic Lesions) trial, presented at the American Heart Association meeting and published simultaneously in the New England Journal of Medicine, offers strong and persuasive evidence that renal-artery stenting is not beneficial.

A total of 947 patients with renal-artery stenosis and either systolic hypertension, despite taking two or more antihypertensive agents, or chronic kidney disease were randomized to medical therapy plus stenting or medical therapy alone. There were no significant differences after 43 months in the primary composite endpoint of cardiovascular and renal events (death from cardiovascular or renal causes, MI, stroke, hospitalization for congestive heart failure, progressive renal insufficiency, or the need for renal-replacement therapy):

Controversy Erupts Over Accuracy Of Cardiovascular Risk Calculator For Guidelines Reply

In the face of a highly critical story in the New York Times by Gina Kolata about the new cardiovascular guidelines, authors of the guidelines and leaders of the American Heart Association and the American College of Cardiology defended the value and integrity of the guidelines.

The Times story claims that the cardiovascular risk calculator used to assess individual risk in the new guidelines is deeply flawed. “In a major embarrassment to the health groups, the calculator appears to greatly overestimate risk, so much so that it could mistakenly suggest that millions more people are candidates for statin drugs.” The story quotes former ACC president Steve Nissen: “It’s stunning. We need a pause to further evaluate this approach before it is implemented on a widespread basis.”

But the guideline authors and AHA/ACC officials strenuously defended the guideline at a news conference Monday morning at the American Heart Association meeting in Dallas. They said  the new risk calculator is far superior to previous efforts, incorporating far more data that now includes stroke assessment and for the first time provides specific predictions for African Americans.

The assembled officials rejected any call to delay implantation of the guidelines, but one author, Donald Lloyd-Jones said that “over time we will modify the risk scores so that they get better and better.”

“We think we’ve done our due diligence,” said AHA president Mariell Jessup. “We have faith and trust in the people who developed the guidelines.”

Press Conference

The Fate Of New Cholesterol Drugs Depends On IMPROVE-IT Reply

Prospects for the highly anticipated new class of cholesterol-lowering drugs, the PCSK9 inhibitors, took a wild roller coaster ride this week. The publication of new lipid guidelines by the American Heart Association and the American College of Cardiology led many observers to think that the promising new drugs under development by Regeneron (in partnership with Sanofi), Amgen, and Pfizer might suffer significant delays.

The guidelines delivered a strong statement questioning the increasingly controversial theory that LDL lowering by itself is beneficial. “We found that non-statin therapies really didn’t provide an acceptable risk reduction benefit compared to their potential for adverse effects in the routine prevention of heart attack and stroke,” said the co-chair of the guideline. This led many observers to think that the FDA would likely require the developers of PCSK9 inhibitors to complete cardiovascular outcome trials before getting US approval. This decision would delay approval for several years.

Then, on Thursday, the companies developing PCSK9 inhibitors received some apparent good news. Bloomberg News reported that an FDA official said that the drugs “will only have to meet the U.S. Food and Drug Administration’s existing standards for clearance, including whether they cut cholesterol and reduce blood pressure or inflammation.”

But then the FDA added one other very important caveat. Here’s how they phrased it to me:

After Long Wait, Updated US Cardiovascular Guidelines Now Emphasize Risk Instead Of Targets 1

Updated cardiovascular health guidelines were released today by  the American Heart Association (AHA) and the American College of Cardiology (ACC). The guidelines are designed to provide primary care physicians with evidence-based expert guidance on cholesterol, obesity, risk assessment, and healthy lifestyle.

The new guidelines reinforce many of the same messages from previous guidelines, but also represent a sharp change in philosophy. That change is most evident in the new lipid guidelines, in which the focus has shifted away from setting numerical targets for cholesterol levels in favor of treatment decisions based on individual risk status.

“This guideline represents a departure from previous guidelines because it doesn’t focus on specific target levels of low-density lipoprotein cholesterol, commonly known as LDL, or ‘bad cholesterol,’ although the definition of optimal LDL cholesterol has not changed,” said Neil J. Stone, chair of the lipid expert panel that wrote the new guideline. “Instead, it focuses on defining groups for whom LDL lowering is proven to be most beneficial.”

The long-awaited and often controversial guidelines are the successors to the extremely influential NHLBI guidelines, including the Adult Treatment Panel (ATP) series of guidelines that brought cholesterol to the consciousness of millions of people. Earlier this year the NHLBI announced that it would no longer issue guidelines but would, instead, provide support for guidelines produced by other organizations. Following the NHLBI announcement, the AHA and the ACC said that they would take over publication of the guidelines.

Observational Study Lends Support to CRT Guidelines Reply

A large observational study published in JAMA suggests that patients with left bundle-branch block (LBBB) and longer QRS duration derive the most benefit from a cardiac resynchronization therapy defibrillator (CRT-D). The findings appear to support current, but often criticized, guidelines from the American College of Cardiology, American Heart Association, and the Heart Rhythm Society, in which a class I recommendation is restricted to patients with LBBB and QRS duration of 150 ms or greater.

The Guidelines Are Dead. Long Live The Guidelines. Reply

Following last month’s surprising announcement that the National Heart, Lung, and Blood Institute would no longer issue guidelines, leaders of the American Heart Association and the American College of Cardiology have now announced that are “officially assuming the joint governance, management and public distribution” of the enormously influential cardiovascular prevention guidelines, including the much-delayed and much-anticipated hypertension and cholesterol guidelines (formerly known as JNC 8 and ATP IV). The ACC and AHA will also assume responsibility for guidelines on cardiovascular risk assessment, cardiovascular lifestyle interventions and obesity.

In an editorial published in Circulation and the Journal of the American College of Cardiology, leaders of the NHLBI, AHA, and ACC provide a little more information on how the new model will work. One important announcement, that “all chairs and members of the current writing panels have been invited to continue to work together with the ACC and AHA to finalize the guidelines,” might indicate that the hypertension and cholesterol guidelines could see the light of day in the not-too-far-distant future. In June the NHLBI’s Michael Lauer expressed confidence that these guidelines would appear in less than a year, but the AHA said that no timeline had yet been established.

Sex And The Cardiac Patient Should Not Be A Taboo Subject 3

It’s not an easy conversation to have. After a heart attack or other major cardiac event, talking about sex is awkward, and often avoided by patients, their partners, and physicians. But a new consensus statement from several major cardiology organizations urges physicians to get over their reluctance or embarrassment and counsel their cardiac patients about this important, but often neglected, aspect of their lives.

After a patient has a heart attack, stroke, cardiac surgery, cardiac device implantation, or is newly diagnosed with a cardiovascular condition, physicians and other healthcare professionals should provide individually tailored information and advice about a wide variety of issues relating to sexual activity, according to the consensus document developed by the American Heart Association (AHA) and the European Society of Cardiology and published in Circulation and the European Heart Journal. The advice “should address topics such as when to resume sex, specific methods and recommended positions, and the role of intimacy without sex,” said the American Heart Association in a press release.

The statement cites numerous concerns, both psychological and physiological, that patients may have after a coronary event, including “general anxiety, fear of having another MI, feeling unwanted by their partner or not good enough, changes in self-perceptions, inadequate knowledge regarding the impact of heart medications, and finally, partner concerns.”

Cardiology Goes Better With Coke 3

Diet Coke - get cancer, not fat

At the bottom of this post I’ve reprinted an email cardiologists are receiving from the American College of Cardiology. See the bottom of the message for the disclosure that Coca Cola is paying for this educational program. I don’t have much to say about this though I wonder what the faculty of this program will say about the role of sugared soda and obesity. I also wonder what position the ACC will take on public health efforts to curb sugar consumption.

There’s no reason to be surprised about this. Last year the president of the ACC was one of 22 participants chosen by the Coca-Cola Company to carry the Olympic Flame. And the ACC is far from the only mainstream medical organization to take money from Big Sugar. Coke pays a lot of money to the National Heart Lung and Blood Institute to put a red dress logo on the Diet Coke label and the American Heart Association has struck deals with, among others, Cheetos and Subway.

See Yoni Freedhoff’s Weighty Matters blog for much more about Coca Cola’s efforts to influence medical organizations.

Here’s the ACC email:

The American College of Cardiology is teaming up with the Preventive Cardiovascular Nurses Association (PCNA) to offer Never Too Early, Never Too Late: Cardiovascular Health for Women Throughout the Lifespan, an educational webinar, on Wednesday, August 14th from 1:00 p.m. – 2:00 p.m. EDT. This complimentary webinaroffers a comprehensive view of women’s cardiovascular health as they age. Our expert faculty, Jo-Ann Eastwood, PhD, RN, CCNS, ANCP-BC and Martha Gulati, MD, MS, FACC, will provide perspectives on clinical encounters during the childbearing years, perimenopausal period and in later life, while presenting opportunities to focus on, when indicated, cardiovascular disease (CVD) risk reduction, and the session will be moderated by JoAnne Foody, MD, FACC. During this webinar, the educators will encourage clinicians to seek and seize opportunities to discuss optimal cardiovascular management with their women patients in clinical practice settings, and as equally important, to champion them with their colleagues in the primary care and women’s health fields.Webinar highlights include:

  • A look at how gestational diabetes, pregnancy-associated hypertension and preeclampsia predict future CVD risk
  • Exploration into the prevalence of hypertension in women vs. men throughout the lifespan
  • Why gender differences matter with regard to tobacco use and cessation
  • The impact of women’s physical activity level on cardiovascular risk
  • Examples of successful cardiovascular health improvement programs targeted to women in a variety of age cohorts
  • One hour of CME, CNE and RD credit

Hypertension And Cholesterol Guidelines Delayed Again As NHLBI Gets Out Of The Guidelines Business Reply

The National Heart, Lung, and Blood Institute (NHLBI) will no longer issue guidelines, including the much-delayed and much-anticipated hypertension (JNC 8) and cholesterol (ATP IV) guidelines. Instead, the NHLBI will perform systematic evidence reviews that other organizations, including the American Heart Association and the American College of Cardiology, will use as a resource for their own guidelines.

The exact fate and form of the delayed hypertension and cholesterol guidelines has not yet been decided, though the NHLBI’s Michael Lauer said he was confident that these guidelines would appear in less than a year. But a lot of work remains before the documents can be published. ACC President John Harold said that  “the ACC has not formally agreed to or begun the process of updating” the NHLBI documents, “but we are open to this role and look forward to working out details with NHLBI and the American Heart Association.”

Dramatic Increase in Use of Radial Artery Access for PCI in the U.S. Reply

In the last six years interventional cardiologists have dramatically increased their use of radial access for PCI, according to a retrospective study published in Circulation. Using data from the CathPCI registry on more than 2.8 million procedures between January 2007 and September 2012, Dmitriy Feldman and colleagues found that radial access PCI increased 13-fold, from a negligible 1.2% at the beginning of the study to 16.1% at the end.

Salt Report From IOM Sparks Much Heat, Only A Little Light Reply

An Institute of Medicine report on salt earlier this week sparked a lot of controversy. The report concludes that there’s no evidence to support current efforts to lower salt consumption to less than 2,300 mg/day. Unfortunately, the press coverage offered little insight into the science behind the issue. On the Knight Science Journalism Tracker blog, Faye Flam deftly uncovers the almost universal shallow coverage in the media.

The one exception, the one story worth reading that “dug into the science,” according to Flam, is Gina Kolata’s story in the New York Times:

The Mediterranean Diet: The New Gold Standard? 1

Earlier today I summarized the important new PREDIMED study published in the New England Journal of Medicine showing the cardiovascular benefits of the Mediterranean diet. This study– a rare and much welcome instance of a large randomized controlled study of a diet powered to reach conclusions about important cardiovascular endpoints– has been widely praised and will undoubtedly have a major effect in the field of nutrition and will influence lots of people to adopt some form of a Mediterranean diet.

The study’s major potential weakness appears to be that the control group didn’t get a fair chance.

Dean Ornish, probably the best-known and most passionate advocate of low-fat diets, goes much further in attacking the credibility of the trial…

The really great thing about the Mediterranean diet, by contrast, is that we know with 100% certainty that it is possible for people to live and eat this way, since they’ve been doing so for millennia. It’s true, though, that the new study didn’t really demonstrate that the Mediterranean diet is better than a true low-fat diet. But it did demonstrate that a Mediterranean diet is healthier than what most people are currently eating. So it’s a good example of a real world trial.

…Now that the Spanish PREDIMED study has been published, I think it must be considered the gold standard. Now it is up to the AHA, and Ornish, to prove that their diets are better than, or even as good as, the Mediterranean diet.

Back To The Future: Resurrected Data From 1960s Trial Might Impact Contemporary Dietary Fat Debate 2

In an exceedingly strange turn of events, data from a clinical trial dating from the 1960s, long thought to be lost, has now been resurrected and may contribute important new information to the very contemporary controversy over recommendations about dietary fat composition.

The American Heart Association has long urged people to increase their consumption of polyunsaturated fatty acids (PUFAs), including omega 6 PUFAs, and reduce their consumption of  saturated fatty acids. The recommendations are based on the simple observation that PUFAs lower total and LDL cholesterol while SFAs have the opposite effect. However, the cardiovascular effects of substituting PUFAs for SFAs have never been tested in randomized, well-controlled clinical trials, and a growing proportion of experts now suspect that simple changes in total cholesterol and LDL cholesterol may not tell the whole story.

One trial that actually tested the hypothesis was the Sydney Diet Heart Study, which ran from 1966 through 1973. In the trial, 458 men with coronary disease were randomized to a diet rich in linoleic acid (the predominant omega 6 PUFA in most diets) or their usual diet. Although total cholesterol was reduced by 13% in the treatment group during the study, all-cause mortality was higher in the linoleic acid group than in the control group. However, in the original publications, and consistent with the practice at the time, deaths from cardiovascular (CVD) and coronary heart disease (CHD) deaths were not published.

Now, in a new paper published in BMJ, Christopher Ramsden and colleagues report that they were able to recover and analyze data from the original magnetic tape of the Sydney Diet Heart Study. The new mortality findings are consistent:

Large Meta-Analysis Finds No Harm Associated With Eggs 2

No food has had more ups and downs over the last century or so than the common egg. Following a long period in which eggs were ubiquitous and highly regarded, eggs fell from favor with the rise of concerns over cholesterol. Currently the American Heart Association recommends that people restrict dietary cholesterol to 300 mg per day, which effectively limits people to 1 egg per day at most. However, the relationship of dietary cholesterol and serum cholesterol  is, at best, tenuous, and a significant number of experts now believe that egg consumption poses no risk to cardiovascular health.

In a new paper published in BMJ, a group of researchers from China and Boston performed a meta-analysis of 8 studies that included 263 938 participants for coronary heart disease (CHD) and 210 404 participants for stroke and followed them for 8 to 22 years. The authors found no evidence for an association between egg consumption and either coronary heart disease or stroke…
