Circulatory disease

Circulatory Disease

Circulatory disease or cardiovascular disease (pronunciation: /ˌkɑːrdi.oʊˈvæskjʊlər diːˈziːz/) refers to a class of diseases that involve the heart or blood vessels.

Etymology

The term "circulatory disease" is derived from the Latin word 'circulatorius' (meaning 'going round in a circle') and the Greek word 'disease' (meaning 'lack of ease').

Types of Circulatory Diseases

Circulatory diseases can be divided into several types, including:

Coronary artery disease: This is the most common type of heart disease and occurs when the coronary arteries, which supply blood to the heart muscle, become hardened and narrowed due to the plaque buildup.

Heart attack: This occurs when a part of the heart muscle doesn't receive enough blood flow. The more time that passes without treatment to restore blood flow, the greater the damage to the heart muscle.

Stroke: This is a disease that affects the arteries leading to and within the brain. A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts.

Peripheral artery disease: This is a common circulatory problem in which narrowed arteries reduce blood flow to your limbs.

Congestive heart failure: This is a type of heart disease where the heart does not pump blood as well as it should.

Related Terms

Atherosclerosis: This is a condition where the arteries become clogged by fatty substances, such as cholesterol.

Hypertension: This is a long-term medical condition in which the blood pressure in the arteries is persistently elevated.

Angina: This is a type of chest pain caused by reduced blood flow to the heart.

Arrhythmia: This is a condition with an irregular heartbeat.

Cardiomyopathy: This is a group of diseases that affect the heart muscle.

Rheumatic heart disease: This is a condition in which permanent damage to heart valves is caused by rheumatic fever.
