Answer 1

Answer: In a normally healthy person, blood pressure values are 120 mm Hg (systolic) and 80 mm Hg (diastolic). When the blood pressure is persistently more than 140 mm Hg systolic pressure and 90 mm Hg diastolic pressure, then it is said to be hypertension or high blood pressure.

Angina pectoris: It is the condition in which there is the pain in the chest which results from a reduction in blood supply to cardiac muscle due to narrowed and hardened coronary arteries. Atherosclerosis and arteriosclerosis can cause this problem. It causes heaviness and severe pain in the chest. Pain can also be felt in the neck, lower jaw, left arm and left shoulder.

Answer 2

Ans= A condition in which the force of the blood against the artery walls is too high.Usually hypertension is defined as blood pressure above 140/90, and is considered severe if the pressure is above 180/120.

Note: Angina pectoris is the medical term for chest pain or discomfort due to coronary heart disease. It occurs when the heart muscle doesn't get as much blood as it needs. This usually happens because one or more of the heart's arteries is narrowed or blocked, also called ischemia.
