Estrogen may protect against heart failure (HF)-related depression by preventing the creation of inflammation-causing chemicals in the brain, according to research published in the American Journal of Physiology.

Women are more likely to survive a heart attack if their emergency room physician is also a woman, according to research published in the Proceedings of the National Academy of Sciences (PNAS).

New research published in the Journal of the American Heart Association suggests light and moderate-to-vigorous physical activity, coupled with less sedentary time, is associated with more favorable levels of heart and vessel disease markers in older individuals.

Most people who suffer a heart attack maintain elevated levels of high-sensitivity C-reactive protein (hs-CRP) several years later, which can only partially be explained by traditional cardiovascular risk factors, researchers reported in the American Heart Journal.

Cardiologists in the U.K. note young investment bankers in their 20s and 30s are being admitted to the hospital more frequently with heart-related conditions, despite employers implementing measures to reduce workload and stress. One cardiologist told Business Insider he has seen a 10 percent increase in heart attacks among bankers under 30.

A hospital protocol incorporating high-sensitivity cardiac troponin T (hs-cTnT) enabled a quicker rule-out of heart attack than a conventional troponin test, according to a research letter published online Aug. 6 in Circulation.

Researchers have developed an online tool to more accurately calculate which middle-aged individuals are at the highest risk of heart attack or stroke during the next 10 years.

Siemens Healthineers received FDA approval of its High-Sensitivity Troponin I assays (TnIH)1 for the Atellica IM and ADVIA Centaur XP/XPT in vitro diagnostic analyzers. The new troponin assays will allow physicians to correctly diagnose patients for acute myocardial infarction (MI).
