| angina pectoris | for chest pain or discomfort due to coronary heart disease. |
| angiotenin receptor blockers | a very potent chemical formed in the blood that causes muscles surrounding blood vessels to contract, thereby narrowing the vessels |
| anoxia | happens when your body or brain completely loses its oxygen supply. |
| antherosclerosis | A process of progressive thickening and hardening of the walls of medium-sized and large arteries as a result of fat deposits on their inner lining. |
| cerebrovascular accident | The sudden death of some brain cells due to lack of oxygen when the blood flow to the brain is impaired by blockage or rupture of an artery to the brain. |
| congestive heart failure | a chronic progressive condition that affects the pumping power of your heart muscles. |
| contractility | the inherent strength and vigour of the heart's contraction during systole. |
| cyanosis | a bluish cast to the skin and mucous membranes. |

| high density lipoprotein | of blood plasma that is composed of a high proportion of protein with little triglyceride and cholesterol and that is associated with decreased probability of developing atherosclerosis. |
| hypertension | a long-term medical condition in which the blood pressure in the arteries is persistently elevated. |
| hyperlipemia | Elevated lipid (fat) levels in the blood. |
| hypoxia | A lower-than-normal concentration of oxygen in arterial blood, as opposed to anoxia, a complete lack of blood oxygen |
| ischemia | deficient supply of blood to a body part (as the heart or brain) that is due to obstruction of the inflow of arterial blood |
| low density lipoprotein | transports cholesterol from the liver to the tissues of the body. |
| myocardial infarction | A heart attack. |
| pulmonary circulaton | the passage of venous blood from the right atrium of the heart through the right ventricle and pulmonary arteries to the lungs where it is oxygenated and its return via the pulmonary veins to enter the left auricle and participate in the systemic circulat |
| shock | critical condition that is brought on by a sudden drop in blood flow through the body. |
| thrombus | he formation of a blood clot, known as a thrombus, within a blood vessel. |
