Heart Disease

What Causes High Blood Pressure?

Blood pressure is the term used to describe the pressure exerted on the arterial walls as blood flows through them. This pressure is at its highest when the heart contracts and pumps blood through the arteries and is called the systolic pressure.

New study identifies shared risk factors for breast cancer and atrial fibrillation

Alcohol use and smoking were linked to breast cancer and atrial fibrillation/flutter in women ages 55 years and older in multiple regions of the world, according to new, independent research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Sleep apnea and erectile dysfunction share a stronger link than expected

A systematic review and meta-analysis of 8 observational studies found that greater obstructive sleep apnea severity was associated with poorer erectile function, with higher AHI linked to lower IIEF scores and higher minimum oxygen saturation linked to higher IIEF scores. The authors caution that the evidence remains observational, heterogeneous, and low certainty, so the findings support targeted screening rather than proving causality.

Yogurt, prebiotics, and probiotics link to lower colorectal cancer odds in U.S. adults

A national NHANES analysis of 9,405 U.S. adults aged 50 and older found that any yogurt, prebiotic, or probiotic consumption was associated with about 50% lower odds of self-reported colorectal cancer. Because the study was cross-sectional, it cannot prove causation but supports further research into microbiota-targeted dietary strategies.
