Exercise as it relates to Disease/Resistance Exercise and its effects on Heart Failure patients

Chronic Heart Failure (CHF) is a serious medical condition in which the heart is no longer able to pump enough blood to meet the body's needs. Underlying problems such as structural abnormalities or cardiac dysfunction will result in impairment of the ventricles to either fill or eject blood; with this becoming an even bigger problem during exercise. CHF often occurs as a result of other heart problems such as myocardial infarction, ischaemic heart disease, hypertension and idiopathic dilated cardiomiopathy. Symptoms of CHF include breathlessness, tiring easily; particularly during exercise, irregular heart beat, oedema in the lower limbs and sudden weight gain as a result from this fluid retention.

NYHA Functional Capacity
The New York Heart Association (NYHA) has developed a table which categorizes the severity of a patients heart failure and their capacity to exercise.
