Hypertension: It is a chronic condition when blood pressure is too high. Blood pressure is the amount of blood pumped by the heart and the amount of resistance exerted by the arteries against the blood flow.  If the heart pumps more blood, then arteries become narrower, and in turn, blood pressure becomes high.  If blood pressure becomes uncontrolled, it may cause serious heart disease, including stroke and heart attack. High blood pressure also causes brain damage (stroke) and kidney failure. Blood pressure is expressed by systolic and diastolic. Systolic blood pressure represents the contraction and relaxation of the heart. Diastolic represents the pressure in the vessels when the heart beats and is in a resting state. Ideal blood pressure should be between 90/60mmHg and 120/80mmHg. Hypertension is detected when systolic blood pressure is more than 140mmHg, and diastolic pressure is higher than 90mmHg. Some symptoms of hypertension include headache, nose bleeding, vomiting, and chest pain.

Angina pectoris: It is the medical term for heart-related chest pain. It occurs when there is a reduction in blood supply to the heart due to the blockage of one or more arteries (coronary heart disease). Patients with angina often explain chest pain as squeezing, tightening, or pressure in the chest. Other symptoms can be dizziness, sweating, heartburn, and difficulty breathing.

Arrhythmia: Arrhythmia is a condition in which your heart beats irregularly, too fast, or too slow. Symptoms of irregular heartbeat include chest pain, shortness of breath, and fast or slow heartbeat. 60 to 100 beats per minute is generally considered a normal heart rate.
