Five types of heart disease are coronary artery disease, cardiomegaly or enlarged heart, heart attack, arrhythmia and heart valve disease, according to WebMD. Another five are cardiomyopathy, or heart muscle disease, pericarditis, Marfan syndrome, heart murmurs and sudden cardiac death.
Sudden cardiac death is caused when the heart stops functioning, claims WebMD. It is responsible for half the deaths due to heart disease and sometimes happens without any prior symptoms. Coronary artery disease is the build-up of plaque in the arteries. This can lead to such conditions as stroke or heart attack.
Coronary artery disease can also lead to an enlarged heart, says WebMD. Heart attack happens when the heart becomes starved of oxygen and part of the heart muscle dies. Arrhythmia is when the heart beats in an irregular way. Heart valve disease happens when the valves that keep the blood flowing properly in and out of the heart malfunction.
With cardiomyopathy, the heart is thickened or not as soft and supple as it should be. This makes it hard for the heart to pump blood efficiently, claims WebMD. Pericarditis is an inflammation of the sac that encloses the heart, and Marfan's syndrome is an inherited disease that attacks the connective tissue. Heart murmurs may be benign or signs of a damaged heart valve.
