Heart failure
The post explains left-sided heart failure, a condition where the left ventricle cannot pump blood effectively, causing blood to back up into the lungs. It outlines major causes such as high blood pressure, coronary artery disease, valve disorders, and cardiomyopathy. Common symptoms include shortness of breath, coughing with pink frothy sputum, fatigue, and rapid heartbeat. The post also highlights diagnostic tests like echocardiograms, chest X-rays, and BNP blood tests, along with key risk factors including hypertension, diabetes, obesity, smoking, and prior heart attacks.
