Ischemic heart disease
Ischemic Heart Disease
Ischemic heart disease (pronounced: is-KEE-mik heart disease), also known as coronary artery disease or coronary heart disease, is a condition that affects the supply of blood to the heart. The blood vessels are narrowed or blocked due to the deposition of cholesterol on their walls. This reduces the amount of oxygen and nutrients reaching the heart.
Etymology
The term "ischemic" comes from the Greek word "iskhaimos", which means "to restrict blood". The term "heart disease" is derived from the Old English "heorte" (heart) and the Latin "dis-ease" (lack of ease).
Symptoms
Symptoms of ischemic heart disease may include chest pain, shortness of breath, and fatigue. These symptoms may become more apparent during exercise or stress.
Causes
Ischemic heart disease is primarily caused by atherosclerosis, a condition where plaque builds up inside the coronary arteries. This can be due to several factors including high blood pressure, high cholesterol, diabetes, and smoking.
Diagnosis
Diagnosis of ischemic heart disease typically involves a physical examination, patient history, and several tests such as an electrocardiogram, stress test, and coronary angiogram.
Treatment
Treatment for ischemic heart disease may involve lifestyle changes, medication, and in some cases, surgery. This can include angioplasty and coronary artery bypass grafting.
