This study was designed to explore risk factors for PH development in patients with advanced heart failure and left ventricular dysfunction. In a retrospective observational study of 419 patients evaluated for heart transplantation due to end stage HF, different variables were analyzed to find predictors of PH (defined as a mean pulmonary pressure >25 mmHg), reactive PH (defined as a transpulmonary gradient >12 mmHg) and severe PH (defined as a mean pulmonary pressure >40 mmHg and/or pulmonary vascular ressistance >3 WU) using a multivariate stepwise logistic regression analysis. Prevalence of PH, out of proportion and severe PH was 62.2%, 23.8%, and 18.8% respectively. The presence of moderate-severe mitral regurgitation [2.1 (1.2-3.7); P=0.006], moderate-severe tricuspid regurgitation [OR 2.9 (1.3-6.4); P=0.005] and a duration of disease >3 years [OR 1.7 (1.1-2.7); P=0.03] were independent risk factors associated with PH. Moreover, the presence of a moderate-severe mitral regurgitation and a duration of disease greater than 3 years, were independent predictors of out of proportion and severe PH.
