Mental stress and anger may worsen heart failure

Mental stress and anger may have clinical implications for patients with heart failure according to a new report published in the Journal of Cardiac Failure.

Heart failure is a life-threatening cardiovascular disease in which the heart is damaged or weakened. This can lead to a reduced ejection fraction, in which the heart muscle pumps out a lower amount of blood than is typical with each contraction.

In this study of patients who had heart failure with reduced ejection fraction, the authors -- including researchers at Yale -- evaluated the effects of stress and anger on diastolic function. Diastolic function describes the ability of the heart to relax and refill between muscle contractions and is predictive of mortality risk.
