TACHYCARDIA IN PREDICTING THE RISK OF DEATH IN IDIOPATHIC DILATED CARDIOMYOPATHY: RESULTS FROM A LARGE REGISTRY OF PTS WITH A LONG FOLLOW-UP

at 2 years (3% vs 3%), 5 years (10% vs 7%) and 10 years (22% vs 18%) (p NS). Finally, the survival rate and the SD rate were similar in more severly impaired pts (with both EF 0,30 and LVEDD 7 cm) with VT (54%, SD 26%) and without VT (51%, SD 19%) but worse than in pts with EF >0,30 and/or LVEDD <7 cm (72%; p <0.001; SD 10%; p=0.0006). Conclusions: ns VT detected at first evaluation were not associated with a higher risk of total or sudden death; pts with a severe left ventricular dysfunction and dilatation had a worse prognosis and higher risk of SD independently from the presence of ns VT.
