Chagas heart disease is common in Latin America. Now, given the growing immigrant population, U.S. physicians need to know how to recognize and treat it. 

A study, published this month in the journal Nature Medicine, tested the effects of a molecule called chaer on animals. Results showed that blocking the molecule prevented them from developing heart failure.

New research published in the BMJ suggests that an irregular heartbeat is linked to other serious conditions, some that can be fatal.

After adjusting for several cardiovascular risk factors, researchers found that none of the four major polyunsaturated fatty acids were associated with cardiovascular mortality in men from Sweden who enrolled in a prospective cohort study. However, linoleic acid was inversely associated with all-cause mortality.

As heart disease remains a pressing issue for many patients, identifying ways to avoid heart failure are at the forefront of physicians’ efforts.

Adults with atrial fibrillation have an increased prevalence of cardiovascular risk factors such as stroke, MI and heart failure years before they are diagnosed with the condition, according to an analysis of a large, community-based cohort.

Heart attacks cause severe damage to the heart, which over time can lead to heart failure. It can be hard to anticipate and even more difficult to prevent, but a new medical product may be able to help.

A systematic review from the Agency for Healthcare Research and Quality (AHRQ) suggests transitional care interventions may reduce all-cause readmissions and mortality rates among patients with heart failure.
