Pre-activating cath labs speeds reperfusion, boosts survival for STEMI patients

ST-segment elevation myocardial infarction (STEMI) patients have better odds of survival if emergency medical services (EMS) personnel alert the hospital where the patient will be arriving ahead of time, according to a study published Sept. 17 in JACC: Cardiovascular Interventions.

HF patients discharged with euvolemia see fewer readmissions

Heart failure patients who are discharged from the hospital before they reach euvolemia—a healthy balance of blood in the body—are more likely to be readmitted in both the short- and long-term, according to research published in the American Journal of Cardiology this month.

‘ASPREE’ finds non-CVD patients derive little benefit from daily aspirin

A daily, low dose of aspirin isn’t preventive against early death or disability in older patients who are otherwise healthy, according to results from the eight-year ASPREE trial that were released Sept. 16.

Dual-energy CTA iodine maps offer small benefit in diagnosing pulmonary embolism

Dual-energy (DE) CT iodine maps offer a slight benefit when paired with traditional CT angiography images in diagnosing pulmonary embolism (PE), reported researchers in a Sept. 11 Radiology study.

2nd carcinogen detected in common heart drug valsartan

The European Medicines Agency (EMA) and the FDA said late last week a second toxin that may cause cancer has been detected in valsartan—a common heart drug that has already been recalled in about two dozen countries due to the presence of N-nitrosodimethylamine (NDMA), a probable human carcinogen.

Warfarin vs DOACs: What’s the best indicator for a switch?

Optimal candidates for a switch from vitamin K antagonists like warfarin to direct oral anticoagulants (DOACs) have long been identified by a single statistic—time-in-therapeutic range—but a recent Danish analysis of anticoagulants in atrial fibrillation patients suggests the marker might be less insightful than previously thought.

Angiographic completeness of PCI not tied to outcomes after FFR-guided stenting

Visual estimations of the completeness of revascularization failed to predict subsequent cardiovascular events for patients with acute coronary syndromes (ACS) who underwent stenting guided by fractional flow reserve (FFR), researchers reported in the Journal of the American College of Cardiology.
