Independent determinants of PH were age, previous cardiovascular disease, the Nt‐pro‐BNP level hs‐TnT, the systolic dysfunction, diastolic dysfunction and left ventricular hypertrophy. Over the follow‐up 94 cardiovascular events occurred, variables associated were: PH, age, history cardiovascular disease, dyslipidaemia, elevated concentration of Nt‐pro‐BNP and hs‐TnT, systolic and diastolic dysfunction, in a multivariate model, the PH maintained its independent association. Mortality data: 88 patients died (41.7%); 35 (29.5%) in the no PH group and 53 (58.5%) in the PH group (<jats:italic>P</jats:italic> < 0.001). In the Cox survival analysis, we found an association between mortality and age, previous cardiovascular disease, history of peripheral vascular disease, Nt‐pro‐BNP levels. In a multivariate model the PH remains as independent predictor of mortality.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>Pulmonary hypertension is a common finding in HD patients and a valuable predictor of mortality and cardiovascular events. Prospective studies are needed to assess the effect of intervention on risk factors in improving patient's outcomes.</jats:p></jats:sec>
