Hypertension is defined as a systolic blood pressure greater than 130mm Hg and a
diastolic pressure greater than 90 mm Hg, based on two or more measurements.
Hypotension is the low blood pressure. When the systolic pressure is less than 90mm Hg.
Arteriosclerosis occurs when the blood vessels that carry oxygen and nutrients from your
heart to the rest of your body become thick and stiff sometimes restricting blood flow to your
organs and tissues.
It is a vascular disease associated with the accumulation of lipids leading to the invasion
of leukocytes and smooth muscle cells into the intima, a process which may proceed to the
formation of plaque on the wall of arteries and vessels.
Angina pectoris is a syndrome characterized by chest pain resulting from an imbalance
between O2 supply and demand and is most commonly caused by the inability of atherosclerotic
coronary arteries to perfuse the heart under conditions of increased myocardial O2 consumption.
MI is defined as a diseased condition which is caused by reduced blood flow in a
coronary artery due to atherosclerosis and occlusion of an artery by an embolus or thrombus.
When the heart is unable to pump blood at a rate sufficient to meet the metabolic
demands of the tissues or can do so only at an elevated filling pressure.
It is defined as loss of cardiac rhythm, especially irregularity of heart beat.
