Myocardium disorders

Cardiomyopathy
Cardiomyopathy is an alteration in the function of the heart muscle. It can occur for several reasons in cats and it can take several forms. When the muscle is sufficiently affected that it can not function properly, heart failure occurs. Cardiomyopathy is the deterioration of the cardiac muscle of the heart wall. Cardiomyopathies can generally be categorized into two groups: ischemic cardiomyopathy and nonischemic cardiomyopathy. Nonischemic cardiomyopathy is weakness in the muscle of the heart that is not due to coronary artery disease.
 
Congestive heart failure
Congestive heart failure (CHF) (also called heart failure) is the inability of the heart to pump blood effectively to the body, or requiring elevated filling pressures in order to pump effectively. Congestive heart failure occurs when the heart is unable to pump blood effectively throughout the body. The term congestive is used because lung congestion causes some of the main symptoms of heart failure. Heart failure does not mean that your heart has stopped working completely. It means that the heart is not pumping as strongly as it should.
 
Cardiac arrest
A cardiac arrest is the cessation of normal circulation of the blood due to failure of the ventricles of the heart to contract effectively during systole. The resulting lack of blood supply results in cell death from oxygen starvation. Cerebral hypoxia, or lack of oxygen supply to the brain, causes victims to immediately lose consciousness and stop breathing. Cardiac arrest is a medical emergency with absent or inadequate contraction of the left ventricle of the heart that immediately causes bodywide circulatory failure.
 
Sudden cardiac death
Sudden cardiac death (also called sudden arrest) is death resulting from an abrupt loss of heart function (cardiac arrest). Sudden cardiac death is an instant unexpected death which occurs within one hour of an abrupt change in a person's stable clinical state. The mechanism is generally a ventricular tachyarrhythmia. The underlying pathology is usually coronary heart disease in middle-aged and elderly persons, but can also be one of the familial well-defined cardiomyopathies such as hypertrophic cardiomyopathy, dilated cardiomyopathy, arrhythmogenic right ventricular dysplasia or long QT syndrome.
 
Cardiac rehabilitation
Cardiac rehabilitation is a physician-supervised program for people who have either congenital or acquired heart disease. Program participants may or may not have had a heart attack or heart surgery (or other heart procedures). Cardiac rehabilitation can often improve functional capacity, reduce symptoms, and create a sense of well-being for patients. A physician may prescribe cardiac rehabilitation for a patient in certain situations. Cardiac rehabilitation services usually include exercise training, risk factor modification, education and counselling.
