BACKGROUND: @entity296 is one important cause of @entity712 in Latin America. @entity67 may be a factor of decompensation in the course of this disease, but there are no data on its prevalence and its main prognostic implications yet. OBJECTIVE: Describe prevalence and prognostic value of @entity67 in @entity296 . METHODS: 56 @entity1 with @entity296 were consecutively selected by two positive serologies and an ejection fraction < 45% in the echocardiogram. The echocardiogram evaluated the presence of @entity1757 using 3 criteria and @entity22286 using 1 criterion. @entity1 were followed for 21    14 months and @entity299 were defined as the combination of death and hospitalization. RESULTS: The average age of the population was 56    10 years, 50% males. Mean ejection fraction was 30    8% and 87% presented functional class I/II (NYHA). The prevalence of @entity22286 was 34% (95% CI: 22%-48%) and @entity1757 had a prevalence of 85% (95% CI: 75%-93%). The prevalence of @entity1757 was similar among @entity1 with QRS duration < 0.12 s or > 0.12 s (85% and 89%, respectively, p = 0.66). Twenty events were recorded. The incidence of combined events was similar in @entity1 with or without @entity1757 (35% versus 38%, p = 0.9) and those with or without @entity22286 (39% versus 34%, p = 0.73). CONCLUSION: @entity1 with @entity296 have high intraventricular and moderate interventricular prevalence of dyssynchrony. The high prevalence is independent from the QRS width. The @entity67 does not have any prognostic value in @entity1 with @entity296 .
