Publicly released report cards based on hospital performance did not result in a measurably greater systemwide improvement in two composite AMI or CHF process-of-care indicators in a Canadian study. But they did appear to stimulate some important changes in delivery of care that could have led to some better outcomes.

The use of coronary CT angiography in the emergency room can successfully triage at-risk chest-pain patients and can do so faster and less expensively than standard diagnostic testing.

Inflation of the paclitaxel-delivering balloon followed by a bare-metal stent failed a randomized noninferiority test against the Cypher sirolimus-eluting stent in previously untreated coronary lesions.

A new postmortem study using high-resolution imaging has found that fractures in drug-eluting stents may be more common than thought. However, the majority of such fractures appear to be low-grade and silent, with likely few clinical implications, say the researchers.

Anticipation is building for full trial results from ARBITER 6-HALTS, plus a better understanding of what went wrong with cangrelor in the CHAMPION trials. Also in the lineup are updates from PLATO, RE-LY, ALLHAT, BARI 2D, STICH, CASCADE, POPULAR, HEARTMATE II, and many more. Indeed, this year's "late-breaking" sessions include more than 30 trials over five days.

Obesity and hypertension were major independent risk factors for left atrial enlargement (itself a risk factor for atrial fibrillation) in an observational, population-based study, but obesity was the strongest predictor.

Just weeks before ARBITER-HALTS 6 results come out at AHA 2009, an MRI study suggests that niacin is better than placebo in statin-treated patients with low HDL, at least for reducing carotid wall area. Experts say they'd also like to see insights into niacin effects on lipid-rich plaque volumes—the more commonly seen end point with MRI.

An additional year of data from the INCREMENTAL study showed that echo-targeted LV lead positioning increased the likelihood of a response to device therapy by about 40% over standard lead placement. But does that difference translate into better long-term outcomes for the patient?

Pericardial fat, which is found around the heart, predicts future CHD events and may even be a better predictor of these than conventional obesity measures, such as BMI and waist circumference, a new study of MESA participants shows.

Data from Japanese atomic-bomb survivors and people exposed to radiation in their jobs show that even low doses of ionizing radiation may contribute to cardiovascular disease risk. British researchers have created a complex mathematical model to better understand the relationship between radiation exposure and heart disease.

Intravenously administered iloprost, a prostacyclin analog, may help prevent contrast-induced nephropathy in patients with renal dysfunction undergoing coronary procedures, a new pilot study suggests.

In those presenting to the ER with chest pain, a prior zero calcium score cannot completely rule out a coronary obstruction, a new analysis of the MESA study has shown. This is likely due to the presence of soft plaques not detected by calcium screening, the researchers say.

Two-thirds of the 156 trials considered by the AHA in preparing a recent guideline failed to even record the ethnic backgrounds of participants, a new study has found. The researchers call for the reporting of race/ethnicity to be mandatory in all clinical trials, and they suggest medical journals should enforce this policy.

Among nearly 1000 consecutive patients who underwent cardiac CT, 41% had noncardiac incidental findings, but just 1.2% of these were clinically significant. While another 7% were "indeterminate," none of these inconclusive findings became clinically significant during follow-up.

The "Principles on Conduct of Clinical Trials and Communication of Clinical Trial Results" echo recent standards set by medical journal editors, but some observers say the document, which has no penalty component, lacks real teeth.

CORRECTED // A study has found that although ultrasound imaging doesn't seem to improve upon the overall success rate of fluoroscopy-assisted femoral-access PCI, it does seem to facilitate the procedure, reducing the risk of access complications by 59% and doubling the first-pass success rate.

After successful PCI, 20% of patients go on to have a MACE at three years and 12% of patients develop events from nonculprit lesions. PROSPECT investigators say, however, that events from these nonculprit lesions are more likely to be unstable angina or progressive angina, rather than harder events such as MI or cardiac death.
