Getting providers and patients with heart failure (HF) to consider a medication’s sodium load is just one of the steps highlighted in the American Heart Association’s (AHA) first-ever scientific statement on medications that may worsen or cause HF. The 35-page document features a comprehensive list of medications that can promote HF through direct myocardial toxicity, increases in blood pressure, high sodium loads, or drug–drug interactions.
The trial randomized 358 patients who had had a recent heart attack to receive placebo or 4 mg/day of Lovaza plus standard care for 6 months. Patients who received the study drug had a lower adverse left ventricular end systolic volume index (LVESVI; an indication of the heart’s pumping ability), less myocardial scarring (fibrosis) in the undamaged areas of the heart, and better levels of some serum biomarkers.
