| الوصف: | Pulmonary arterial hypertension is known to be related to worse prognosis in patients with heart failure (HF). Quantification of pulmonary vascular resistance (PVR) still requires invasive right heart catheterization. Recent studies have shown an accurate method for non-invasive estimation of PVR by cardiac magnetic resonance (CMR). Our aim was to evaluate the prognostic value of PVR calculated by CMR in patients with congestive HF.We calculated PVR by CMR in 132 patients [age 65.6 ± 13.1 years, left ventricular ejection fraction (LVEF) 35.1 ± 16.4%, ischaemic aetiology 40%] recently admitted for decompensated HF and derived to our cardiac imaging unit for diagnosis. Patients with cardiac events (readmission for HF or all-cause death) had higher values of PVR [6.77 ± 1.9 vs. 4.1 ± 1.6 Wood units (Wu), P0.001] during follow-up [mean 10.3 (1-31) months]. In multivariable Cox regression analysis, only a PVR ≥5.2 Wu [hazard ratio (HR) 4.27; 95% confidence interval (CI) 1.75-10.42; P0.001) and the presence of late gadolinium enhancement (LGE) on CMR (HR 2.24; 95% CI 1.03-4.86; P = 0.04) were independent predictors for adverse events at follow-up.Non-invasive estimation of PVR by CMR might be useful for risk stratification of patients with chronic HF, irrespective of aetiology or LVEF. |
