Cardiac contractility, or pumping ability, is an important part of heart function. The heart's conduction and circulatory systems may be fine, but if the heart muscle doesn't contract well, significant symptoms can result.
We can assess contractility through an echocardiogram which is an ultrasound test of the heart. Many things can affect how well the heart contracts. These include certain medications, heart attacks, overuse of alcohol, and cardiomyopathy (primary heart muscle disease). The causes of decreased contractility and treatment options should be discussed with your cardiologist.
