| ACE inhibitor | an antihypertensive drug that blocks the formation of angiotensin II in the kidney, leading to relaxation of the arteries |
| anemia | A condition marked by a deficiency of red blood cells or of hemoglobin in the blood, resulting in pallor and weariness. |
| aneurysm | An excessive localized enlargement of an artery caused by a weakening of the artery wall. |
| angina | 1.A condition marked by severe pain in the chest, often spreading to the shoulders, arms, and neck, caused by an inadequate blood supply |
| angioplasty | Surgical repair or unblocking of a blood vessel, esp. a coronary artery. |
| anticoagulant | Having the effect of retarding or inhibiting the coagulation of the blood. |
| aplastic anemia | Deficiency of all types of blood cells caused by failure of bone marrow development. |
| arrhythmia | A condition in which the heart beats with an irregular or abnormal rhythm. |
| atherectomy | a minimally invasive surgical method of removing, mainly, atherosclerosis from a large blood vessel within the body |
| atheroma | 1.Degeneration of the walls of the arteries caused by accumulated fatty deposits and scar tissue. |
| atherosclerosis | A disease of the arteries characterized by the deposition of plaques of fatty material on their inner walls. |
| atrial fibrillation | fibrillation of the muscles of the atria of the heart. |
| automated external defibrillator | an electronic apparatus used to counteract atrial or ventricular fibrillation by application of a brief electric shock |
| beta-blocker | Any of a class of drugs that prevent the stimulation of the adrenergic receptors responsible for increased cardiac action |
| blood dyscrasia | any abnormal condition of the blood |
| bradycardia | Abnormally slow heart action |
| cardiac arrest | A sudden, sometimes temporary, cessation of function of the heart |
| cardiac catheterization | the insertion of a catheter into a chamber or vessel of the heart |
| cardiomyopathy | Chronic disease of the heart muscle |
| carotid endarterectomy | a surgical procedure used to prevent stroke |
| cholesterol | A compound of the sterol type, C27H45OH, found in most body tissues and important in metabolism |
| chronic venous insufficiency | a medical condition where the veins cannot pump enough oxygen-poor blood back to the heart |
| coronary thrombosis | A blockage of the flow of blood to the heart, caused by a blood clot in a coronary artery |
| defibrillation | The stopping of fibrillation of the heart by administering a controlled electric shock in order to allow restoration of the normal rhythm |
| diuretic | Causing increased passing of urine |
| electrocardiogram | A record or display of a person's heartbeat produced by electrocardiography |
| embolism | Obstruction of an artery, typically by a clot of blood or an air bubble |
| embolus | a mass of clotted blood or other material brought by the blood from one vessel and forced into a smaller one |
| endocarditis | Inflammation of the endocardium |
| erythrocytes | A red blood cell that (in humans) is typically a biconcave disk without a nucleus |

| myelodysplastic syndrome | a disease that is associated with decreased production of blood cells |
| myocardial infarction | Necrosis of a region of the myocardium caused by an interruption in the supply of blood to the heart, usually as a result of occlusion of a coronary artery |
| orthostatic hypotension | an abnormal decrease in blood pressure when a person stands up. This may lead to fainting. |
| paroxysmal atrial tachycardia | A period of very rapid and regular heart beats that begins and ends abruptly |
| pericardium | the fibroserous sac enclosing the heart and the roots of the great vessels |
