Types of heart disease
Coronary heart disease.Blocked or clogged arteries limit blood flow to the heart and starving it of oxygen and nutrients.
- Heart's electrical system
Arrhythmia. The heart beats irregularly.
- Dilated ventricle, reduced blood volume
Heart failure. The heart can't pump as powerfully as it needs to in order to supply the body with oxygen and nutrients, causing the heart muscles to overwork and weaken.
- Heart valve disease. One of more of the hearts' valves - which control blood flow into and out of the heart doesn't work.
- Enlarged heart muscle
Cardiomyopathy. An enlarged or abnormally stiff or thick heart, causing the heart to pump weaker than normal and sometimes leading to heart failure or arrhythmia.
Pericarditis. An inflammation of one or more layers of the pericardium, a thin membrane than lines the heart.
Aorta disease. A portion of the aortic wall weakens and balloons out, forming an aneurysm.
- Vascular disease. Heart disease is often related to diseases of the circulatory system, including arteries, veins and lymph vessels, or blood disorders.
