What type of cardiac disability is caused by an insufficient supply of oxygenated blood to the heart?

Ischemic heart disease is a condition characterized by the insufficient supply of oxygenated blood to the heart muscle, typically as a result of narrowed or blocked coronary arteries. When the heart does not receive enough oxygen, it can lead to various issues, including angina (chest pain) and heart attacks. The term "ischemia" specifically refers to the lack of blood flow (and thus oxygen), which can impair the heart's ability to function properly.

In contrast, congestive heart failure involves the heart’s inability to pump effectively and can result from a variety of factors, including previous ischemic damage. Arrhythmia refers to irregular heart rhythms that may or may not result from ischemic conditions, while congenital heart disease involves structural issues with the heart that are present from birth, rather than a lack of blood supply due to blockage or narrowing.
