ABSTRACT
Introduction: pulmonary hypertension is a common finding in heart failure. The use of sildenafil in these cases is a common practice, but still controversial due to the limited number of studies carried out.Objective: to compare echocardiographic variables of pulmonary hemodynamics, in patients with left ventricular systolic dysfunction and severe secondary pulmonary hypertension, before and after the use of sildenafil.
Materials and methods: a cohort study was led, including 19 patients; a two-year follow-up was carried out. Clinical, laboratory and echocardiographic variables were analyzed. The main pulmonary hemodynamics variables were evaluated before the use of sildenafil and 12 weeks after its indication. A survival curve was performed at the end of the follow-up. The statistical significance level used was p < 0.05.
Results: the average age was 56.16 ± 15.77 years, and male sex predominated with 73.3 %. Survival at the end of the follow up was 78.9 %. The main echocardiographic variables of pulmonary hemodinamics showed a significant reduction at 12 weeks of treatment with sildenafil. The survival of patients with a 25 % reduction in pulmonary pressures in the echocardiogram performed at 12 weeks of treatment was greater at the end of the study (100 % vs 33 %, log-rank test p = 0.001).
Conclusions: after using sildenafil, a significant reduction of pulmonary hemodynamics variables was found in the evolutionary echocardiogram. Survival was higher in patients who had this reduction.
