How is restrictive cardiomyopathy diagnosed?

Restrictive cardiomyopathy is diagnosed based on medical history, physical exam, and diagnostic tests. Diagnostic work-up may include electrocardiogram, chest X-ray, echocardiogram, exercise stress test, cardiac catheterization, CT scan, MRI and radionuclide studies.

What does cardiomyopathy look like on echocardiogram?

On standard echocardiogram findings that constitute ischemic cardiomyopathy include regional wall motion abnormalities, wall thinning with aneurysmal dilatation of the infarcted myocardial segment, left ventricular (LV) cavity dilatation and decline in LV systolic performance that is out of proportion to the degree of …

Can you see cardiomyopathy in Echo?

Dilated cardiomyopathy is characterised with echocardiography by the presence of a dilated left ventricle with impaired ventricular systolic function. The aetiology of this form of cardiomyopathy may be idiopathic, familial, viral, ischaemic or immunological.

What is restrictive cardiomyopathy?

Restrictive cardiomyopathy (RCM) is a condition where the chambers of the heart become stiff over time. Though the heart is able to squeeze well, it’s not able to relax between beats normally. This makes it harder for the heart to fill with blood. The blood backs up in the circulatory system.

Does restrictive cardiomyopathy affect cardiac output?

Patients typically have reduced compliance (increased diastolic stiffness), and the left ventricle cannot fill adequately at normal filling pressures. Reduced left ventricular filling volume leads to a reduced cardiac output.

What are the findings of Echo?

During an echocardiogram, a doctor can see:

the size and thickness of the chambers.
how the valves of the heart are functioning.
the direction of blood flow through the heart.
any blood clots in the heart.
areas of damaged or weak cardiac muscle tissue.

How is restrictive cardiomyopathy treated?

Water pills (diuretics) to reduce swelling.
Medicine such as rate-lowering calcium channel blockers or beta-blockers to reduce the heart’s workload and increase its efficiency.
Medicine such as ACE inhibitors to help the heart pump better.

What are the findings of echo?

What heart problems can an echocardiogram detect?

An echocardiogram can help your doctor diagnose several kinds of heart problems, including:

An enlarged heart or thick ventricles (the lower chambers)
Weakened heart muscles.
Problems with your heart valves.
Heart defects that you’ve had since birth.
Blood clots or tumors.

Is cardiac tamponade restrictive or constrictive?

Although uncommon, restrictive cardiomyopathy, constrictive pericarditis, and cardiac tamponade are among the disorders that may affect primarily diastolic function with preservation of systolic function.

What is the cause of restrictive cardiomyopathy?

Restrictive cardiomyopathy is a rare condition. The most common causes are amyloidosis and scarring of the heart from an unknown cause. It also can occur after a heart transplant.
