A new study published today showed that while the sodium content of processed foods declined from 2005 to 2011, the overall reduction was just 3.5%. Restaurants, on the other hand, fared even worse, with researchers reporting that sodium levels actually increased by 2.6% over the same six-year period.

N-3 fatty-acid supplementation had no effect on the study's primary end point in this group of patients with multiple cardiovascular risk factors or atherosclerotic disease, but no previous MI. Researchers also saw no effects on the rate of death from coronary causes or sudden death from cardiac causes or major ventricular arrhythmias.

The AHA is reminding physicians in clinical practice that the domains of patient-reported health status, including symptom burden, functional status, and health-related quality of life, remain underused despite their usefulness in informing clinical decision making and understanding disease burden.

A nationwide cohort study in Denmark helps to soften the message from a 2012 study linking the antibiotic to an increased risk of cardiovascular death in the elderly, likely from ventricular arrhythmias, according to researchers; the hazard doesn't seem to apply to younger people in the general population.
