The diagnosis is usually based on a physical examination, echocardiography, and other tests as needed.
Restrictive cardiomyopathy is a form of cardiomyopathy in which the walls of the heart become rigid.
People with restrictive cardiomyopathy usually feel tired and weak, and have shortness of breath, especially during exercise.
Obtaining early treatment for diseases that might cause restrictive cardiomyopathy might prevent or slow the development of heart wall stiffness.
The heart muscle of the ventricles becomes rigid
The prognosis for patients with restrictive cardiomyopathy is poor. If the disease process causing the problem can be treated, the damage to the heart muscle may be stopped.

Congestive cardiomyopathy
If the results from a methacholine challenge come back positive, then the patient is diagnosed with asthma or airway restrictive disease.
Primary cardiomyopathy not elsewhere classified
Cardiomyopathy is not common (affecting about 50,000 persons in the United States)
Cardiomyopathy is a disorder of the heart muscle. There are four main types of cardiomyopathy: * Dilated cardiomyopathy - where the heart dilates (enlarges). * Hypertrophic cardiomyopathy - where the heart muscle becomes thickened ('hypertrophied'). * Restrictive cardiomyopathy - where the heart muscle cannot relax properly between heartbeats. This is rare. * Arrhythmogenic right ventricular - a rare type which mainly affects the right side of the heart. Dilated cardiomyopathy In this condition the heart muscle is weakened. The ventricles then dilate (enlarge) as their muscular walls are weaker and more 'floppy' than normal. Therefore, the heart does not pump blood as strongly as normal. (Note: other common heart conditions can cause a dilated heart. For example, coronary heart disease, high blood pressure and heart valve disease. These conditions can put a 'strain' on the heart which may cause the heart to dilate. With dilated cardiomyopathy, the heart dilates because of a problem or disease of the heart muscle itself.) About 2 in 10, 000 people in the UK develop dilated cardiomyopathy each year. People at any age and either sex may be affected.
