2. Introduction Cardiovascular disease (CVD) is caused by disorders of the heart and blood vessels, and includes coronary heart disease (heart attacks), cerebro-vascular disease (stroke), raised blood pressure (hypertension), peripheral artery disease, rheumatic heart disease, congenital heart disease and heart failure. CVDs are the number one cause of death globally. Blood pressure (BP) is the pressure applied by circulating blood upon the dividers of blood vessels. At the point when utilized without further detail, "blood pressure" as a rule alludes to the arterial pressure in the systemic course. Blood pressure is normally communicated as far as the systolic (most extreme) pressure over diastolic (least) pressure and is measured in millimeters of mercury (mm Hg). It is one of the crucial signs alongside respiratory rate, heart rate, oxygen immersion, and body temperature. Typical resting systolic (diastolic) blood pressure in a grown-up is roughly 120 mm Hg (80 mm Hg), shortened "120/80 mm Hg"[3]. Blood pressure differs relying upon circumstance, action, and disease states. It is managed by the anxious and endocrine frameworks. Blood pressure that is low because of a disease state is called hypotension, and pressure that is reliably high is hypertension. Both have numerous causes which can run from mellow to extreme. Both might be of sudden onset or of long term. Long term hypertension is a danger element for some diseases, including kidney failure, heart disease, and
