Definitions
Cardiology is the specialty that is concerned with heart disorders and problems. It includes diagnosis and treatment of congenital heart defects (defects in the structure of the heart and other blood
vessels present at birth), coronary artery disease, heart failure, diseases of the heart valves and electrophysiology (the electrical activities of the heart). Specialists in this field are called cardiologists.moreHypertension means high blood pressure, usually defined as a repeatedly elevated blood pressure exceeding 140 over 90 mmHg (a systolic pressure above 140 with a diastolic pressure above 90).
Hypertension can cause such conditions as blood vessel changes in the retina (at the back of the eye), abnormal thickening of the heart muscle, kidney failure, and brain damage. Regular blood pressure checks help with diagnosis. In most cases, no specific cause is found. Hypertension is treated with regular aerobic exercise, weight reduction for those overweight, salt restriction, and medications to control blood pressure.more
