ASCET is the first study since CAPRIE to compare aspirin and clopidogrel as single antiplatelet therapy in patients with stable CAD; further, it used a platelet-function test to examine the interplay of aspirin responsiveness with treatment. The trial hints at better outcomes with clopidogrel in aspirin nonresponders.

A new study is the first to demonstrate that low levels of cardiac troponin T, as detected by a highly sensitive assay, are associated with new-onset heart failure and cardiovascular death in older individuals. But more research is needed to see whether tracking low levels of troponin in this population will be clinically useful, say the researchers.

New registry data show how coronary computed tomography angiography can be used to predict mortality risk more accurately than traditional risk factors in symptomatic patients.

Canadian primary-care physicians are not accurately assessing cardiovascular risk in middle-aged adults, a particular concern for high-risk patients classified as low risk. The implications of the study are that a sizable proportion of these patients might not be prescribed lipid-lowering therapy, say researchers.
Heart failure
1 COMMENT - Nov 23, 2010 10:00 EST
Adjusting heart-failure medications with the goal of reducing natriuretic peptides to a prespecified level, which has produced mixed results in a number of small trials, significantly improved outcomes in yet another small study. A large multicenter randomized trial would be welcome, observers say.

A networkwide effort to get patients with STEMI symptoms to come to the hospital faster is reducing the total time to reperfusion in Minnesota and offsetting some of the longer door-to-balloon times in rural areas.

The condition, which results in a yellowish collection of fatty cholesterol around the eyelids, is usually seen by family doctors and dermatologists but should serve a marker of underlying atherosclerotic disease, even in patients with normal cholesterol levels, say researchers.
Hypertension

Teenagers eat the most salt of any age group in the US and as such represent a key target for sodium-reduction policies, with the adolescent years being "a window of opportunity" to set up lifelong good eating habits, say researchers. Cutting the amount of salt teens consume by a third could cut hypertension by half and reduce deaths at age 50 by almost 10%, they calculate.

Among MESA patients meeting criteria for statins based on JUPITER who have a high coronary artery calcium score, the risk of cardiovascular events is significantly greater than those without calcification, suggesting that calcium screening with computed tomography might be used to further stratify at-risk patients for statin therapy.

UPDATED WITH COMMENTARY // Heart-failure management guided by various remote-monitoring strategies has improved outcomes in mostly observational studies, not randomized trials. Now two such prospective, controlled trials suggest that telemonitoring doesn't cut the risk of hospitalizations or death, after all. Two expert observers declare the strategy all but dead.

The improved survival signal was seen despite an increased risk of bleeding with prasugrel vs clopidogrel. At least one outside commentator is not convinced, saying the analysis is "highly confounded" and makes many assumptions.

A new study indicates that disparities still exist in the invasive treatment of cardiovascular disease in Massachusetts, despite that state's Health Care Reform Act of 2006. Data from Australia, however, illustrate the success of a universal healthcare system.

To CRP or not to CRP, that is the conundrum: the post hoc analysis found that there was little benefit from adding the biomarker to standard risk assessments. Or is there? A number of experts weigh in.

1 COMMENT - Nov 17, 2010 17:45 EST
Device-detected arrhythmias in patients with pacemakers were associated with a 2.5-fold increase in the risk of ischemic stroke and systemic embolism. For patients with a CHADS2 score >2, atrial tachyarrhythmias increased absolute stroke risk to 2% per year.

The ASSERT trial shows that the oral agent RVX-208 increases levels of apoA-1 and thereby mobilizes high-density lipoproteins, especially large alpha-1 HDL particles, but the trial did not meet its primary end point of increase in apoA-1 level vs placebo.

UPDATED WITH COMMENTARY // With the dramatic changes in LDL- and HDL-cholesterol levels and no apparent off-target blood pressure, electrolyte, and aldosterone effects, as well as no adverse safety signal that plagued torcetrapib, DEFINE investigators are optimistic about a larger morbidity and mortality trial with HDL-raising therapy. As one expert put it, "We've gone as far with statins as we can go."

UPDATED WITH COMMENTARY // The possibility of an interventional approach providing a successful treatment option for patients with resistant hypertension has edged nearer with the success of renal sympathetic denervation in the SYMPLICITY HTN-2 trial. Although the results will require confirmation, they raise the tantalizing possibility of a cure for hypertension.

With another negative erythropoietin trial, investigators are debating whether to give up on the investigational treatment or continue to look for ways to use EPO to reduce infarct size following successful PCI for STEMI.

In patients needing a coronary stent 3 mm in diameter or larger, drug-eluting stents do not increase the risk of late cardiac events compared with bare-metal stents, the results of BASKET-PROVE show.

The findings, from the ACT trial, the largest randomized study to date, provide solid evidence that N-acetylcysteine is not effective in the angiography setting and should no longer be used for the prevention of contrast-induced nephropathy, according to investigators.

The largest gene-therapy trial ever in critical limb ischemia has failed to show a significant benefit of this approach in these very sick patients. The findings, "which are definitely negative," emphasize the importance of properly conducted phase 3 trials, say the investigator and others.

UPDATED WITH COMMENTARY // The disappointing results of this eagerly awaited study show an identical rate of the composite end point in both groups.

Nov 16, 2010 08:00 EST
Intracoronary rather than intravenous administration had differing effects on two measures of myocardial reperfusion, improving myocardial blush grade but not ST-segment resolution, the primary end point. Infarct size was also smaller in the intracoronary group, but any benefits could have been due to better artery patency at baseline.

CORRECTED // The full final results, showing no impact of device closure on a composite end point of risk of stroke or TIA at two years, should prompt physicians to look harder for a true cause of cryptogenic strokes, rather than finding and closing a hole and assuming they've solved the problem.

Neither the SmartDelay programming option nor echocardiography-guided AV delay produced superior results to fixed AV-delay programming in the SMART-AV cardiac resynchronization trial.

Given the advanced age and multiple comorbidities in inoperable aortic-stenosis patients, the finding of a large improvement in quality-of-life end points may be as "equally important" a finding as improved survival.

Nov 15, 2010 16:45 EST
The first comparative clinical study of CYP2C19 genotype on ticagrelor pharmacodynamics shows that the new investigational antiplatelet agent is better at inhibiting platelet function than clopidogrel, irrespective of genotype or metabolizer status. The findings confirm the previous results of the PLATO pharmacogenetics substudy, say the researchers.

Using NHANES III data, researchers showed that although blacks are more likely to be vitamin-D deficient, that deficiency did not appear to affect the risk for fatal stroke, unlike in whites.

UPDATED WITH COMMENTARY // ROCKET AF, as previously reported, met its primary end point of noninferiority, but one of two prespecified superiority analyses, the gold standard intention-to-treat, failed to show the drug was better than warfarin for the prevention of thromboembolic events in patients with nonvalvular AF. The second per-protocol on-treatment analysis, however, showed superiority.

New data from multiple studies suggest that clinicians are pulling the plug too early in hypothermia-treated cardiac-arrest patients. One study suggests that 5% to 10% of these patients have a chance of surviving if clinicians give them more time than the arbitrary 72-hour cutoff.

Five years ago, one of the biggest, most burning questions in cardiology was whether the once-popular IV vasodilator hurt or helped in acute decompensated heart failure. The trial designed to settle the issue now says no to the first and yes, but only a little bit to the second, in the short term.

Nov 14, 2010 16:35 EST
The ADVANCE study, looking at the use of a new, smaller, left ventricular assist device as a bridge to transplant, has shown that it is noninferior to the currently available LVAD, the HeartMate II. Although long-term data are needed, these early results are encouraging and suggest the new device is yet another option for such patients. And an ongoing head-to-head study of the two devices in the arena of destination therapy will also prove very interesting, say observers.

For some people, it's something else to "blame" on mom, dad, brother, or sister, at least partly. The adjusted risk of developing atrial fibrillation went up 40% for those with a parent or sibling also with the arrhythmia.

This year's lineup of late-breaking trials includes some of the most eagerly anticipated trials of recent memory, looking at everything from nesiritide, rivaroxaban, and anacetrapib to platelet-function tests and CRP-guided therapy to PFO closure, renal sympathetic denervation, and a new nonpulsatile VAD.
