A study suggests an increased risk of cardiovascular and heart diseases during the mid-life of those women who had at least three traumatic events in their lifetime. The study has found a poorer endothelial function in those women.
Endothelial dysfunction (or malfunction) is a risk factor for heart diseases. It is a precursor to the worsening vascular health and to the development of atherosclerosis. Atherosclerosis is a hardening of arteries leading to high blood pressure (or hypertension). The researchers have found an enhanced risk of heart diseases especially after menopause (postmenopausal).
The researchers came to this conclusion after conducting a study among 272 non-smoking women, either perimenopausal or postmenopausal, aged between 40 and 60 years. The researchers have collected the traumatic events of the participants such as.
This study underscores the importance of psychosocial factors such as traumatic events. Experts suggest that healthcare professionals should consider the traumatic events of a woman when assessing their risk of heart diseases. Some traumatic events reported by the participants were:

The study was presented at The North American Menopause Society's annual meeting, held October 11-14, 2017 in Philadelphia. The study was published on October 11, 2017, in the ScienceDaily. Title of the article was "Traumatic events take toll on the heart: New study links traumatic experiences with increased risk of heart disease, especially after the menopause transition."
An earlier study shows that about 25 percent of American adults over 40 years of age are at a risk of atrial fibrillation (a quivering or irregular heartbeat. Arrhythmia). A study has been conducted by the researchers to find out the association between alcohol consumption and atrial fibrillation (Afib). The study shows a lower risk of atrial fibrillation by not consuming alcohol.
Atrial fibrillation increases the risk of blood clots. The formation of blood clots can increase the risk of stroke or heart attack. The study shows 13 percent increased risk of atrial fibrillation with every decade of alcohol consumption and four percent increased risk of atrial fibrillation with an additional drink per day during that period.
The senior author of the study was Dr. Gregory Marcus, MD, Director of Clinical Research, the UCSF Division of Cardiology, University of California. The study was published on October 18, 2017, in the journal PLOS ONE. Title of the article was "Past alcohol consumption and incident atrial fibrillation: The Atherosclerosis Risk in Communities (ARIC) Study."
