Association between echocardiographic markers of pulmonary hypertension and short-term prognoses in patients with acute heart failure

Introduction: The prognostic value of pulmonary hypertension (PH) estimated by echocardiography in patients with acute decompensated heart failure (ADHF) is poorly studied. This study aimed to evaluate the association between echocardiographic markers of pulmonary hypertension and short-term prognoses in patients with AHF. Materials and Methods: This prospective cross-sectional study was conducted on patients with acute heart failure admitted to Golestan and Imam Khomeini hospitals in Ahvaz, Iran, in 2020. A total of 259 consecutive patients with ADHF underwent an echocardiographic evaluation to assess the probability of PH and right ventricular dysfunction (TAPSE<16 mm). The patients were followed up for six months after hospital discharge, and their outcome was recorded. The probability of PH was estimated based on European Society of Cardiology (ESC) guidelines for echocardiographic evaluation. Kaplan-Meier method was used to determine the cumulative survival rate and the Cox regression model to define the hazard ratio. Results: During six months of follow-up, the all-cause mortality rate was 118 (45.55%), including 106 cardiovascular deaths (40.92%).
