Alcohol can raise blood pressure, cause irregular heartbeats, weaken the heart muscle (cardiomyopathy), increase triglyceride levels, promote clot formation, and trigger inflammation, all of which heighten the risk of heart attack, stroke, and heart failure, even with moderate consumption.
Hypertension damages arteries, leading to atherosclerosis, heart attack, stroke, heart failure, and arrhythmias. It strains the heart, thickens the left ventricle, impairs blood flow, and increases the risk of aneurysms, ultimately weakening overall cardiovascular function and elevating mortality risk.
