The clinical and echocardiographic pattern of the dilated cardiomiopathy (DCM) secondary to hypertension is not well study. We try to compare the clinical and echocardiographic patterns of the hypertensive DCM compared with primary DCM. From a record of the 100 firstly diagnosed consecutive DCM in black patients during 2002 we selected patients with primary DCM and the ones secondary to hypertension (HTA). All the other forms of DCM as diabetic, chronic renal failure, frequency induced, ischemic, HIV positive and alcoholic patients were excluded. DCM was diagnosed if the left ventricle diastolic diameter (LVDD) was bigger then 117% of the expected value (Henry formula) and if ejection fraction (EF) was inferior to 40%. DCM secondary to hypertension was defined if there was a blood pressure (BP) equal or above 140/90 mm Hg or a previous history of hypertension. All patients were submitted to a clinical exam, biochemical analysis and a bidimensional guided m mode evaluation of the left ventricular measures using the ASE standards. 61 patients were selected, 31 with primary DCM (15 females) and 30 with DCM secondary to HTA (11 females). Patients with DCM secondary to HTA were older (61±16 v 53±13 years old p
