Ischemic Cardiomyopathy
Ischemia or ischemic cardiomyopathy is a term that doctors mostly use for heart muscle disease caused by less supply of blood and oxygen to the cardic muscles. Ischemic means Not getting enough blood or oxygen and cardio means Heart Myo means Muscles and Pathy means Disease.
Heart muscle Disease which is due to the lack of oxygen provided to the heart muscles is called as Ischemic Cardiomyopathy. Severe heart injury caused by a major heart attack or multiple smaller heart attacks may result in heart enlargement and thinning of the chamber walls-abnormalities resembling those observed in dilated cardiomyopathy. This type of heart disease, called ischemic cardiomyopathy.
Typically develops in patients with severe coronary artery disease, often complicated by other conditions such as diabetes and hypertension. Heart failure symptoms in ischemic cardiomyopathy are similar to those found in dilated cardiomyopathy. However, ischemic heart disease is more likely to be accompanied by symptoms of coronary artery disease, such as angina (chest pain).
Diagnosis is typically based on a history of heart attacks and studies that demonstrate poor function in major portions of the left ventricle. The diagnosis of Ischemic Hear Disease can be confirmed by coronary angiography, which reveals areas of narrowing and blockage in the coronary blood vessels. Patients with ischemic cardiomyopathy are treated with medications that relieve heart failure symptoms and improve blood flow through the diseased coronary arteries (nitroglycerine, some types of calcium channel blockers, and ACE inhibitors).
When symptoms of heart failure and coronary artery disease cannot be controlled with medications, coronary angioplasty or surgery may be considered. Angioplasty and coronary artery bypass grafting may help increase blood flow to the heart, which in turn enhances heart muscle function. When heart failure symptoms are advanced and cannot be improved by drug therapy or surgery, patients may be referred for a heart transplant. Patients with ischemic cardiomyopathy now account for approximately half of all heart transplant recipients.
