Non-dilated cardiomyopathy in Nigerians evaluated by echocardiography.

Non-dilated cardiomyopathy (NDCM), a condition said to be uncommon, has been found to occur in 4.6% of cases undergoing echocardiography in our centre. Its echocardiographic features have been given (normal cavity dimensions, reduced contractility, thick walls) and clinical implications highlighted. Since it is not an entirely innocuous state, patients should, when discovered, be followed up closely. This would afford clinicians the opportunity to determine factors that lead to stability or deterioration of DCM.
