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.

Study reveals what drives PFAS exposure in firefighters and how risks may be reduced

A large U.S. firefighter cohort study identified personal, occupational, and department-level predictors of serum PFAS concentrations, highlighting both modifiable exposures and persistent background sources. Some protective practices, blood or plasma donation, and drinking water sources were associated with differences in specific PFAS analytes, although causal relationships require further longitudinal study.
