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 why US life expectancy gains stalled after decades of progress

A PNAS study analyzing US mortality from 1979 to 2023 reveals that life expectancy stagnation reflects both worsening outcomes in post-1950 birth cohorts and a broad mortality deterioration beginning around 2010. Cardiovascular mortality slowdowns, rising external causes, and cohort-specific patterns help explain the persistent decline in longevity gains.

Specific gut bacteria may signal long-term risk of heart and metabolic disease

Researchers analyzed gut microbiome profiles from 4,792 adults in the HELIUS cohort and tracked cardiometabolic outcomes over time to determine whether specific microbes predict disease risk. Certain microbes were linked to higher or lower cardiovascular risk, while plant-derived microbial metabolites suggested potential diet–microbiome interactions influencing heart health.
