Does post-acute pre-discharge echocardiographic assessment of RV dysfunction predict long-term all-cause mortality in patients with low- and intermediate-risk pulmonary embolism?
In patients with low- and intermediate-risk pulmonary embolism, post-acute pre-discharge tricuspid regurgitation systolic velocity is an independent predictor of long-term all-cause mortality.
Hazard Ratio: 1.73 (95% CI 1.033–2.897)
p-value: p=0.037
The aim of our study was to asses the long-term prognostic impact of post-acute, pre-discharge echocardiographic assessment of right ventricular (RV) dysfunction in patients with low- and intermediate-risk pulmonary embolism (PE). Consecutive patients with acute PE underwent post-acute, pre-discharge echocardiographic assessment of RV dysfunction (defined by: RV dilation, tricuspid anulus peak systolic excursion, or tricuspid regurgitation systolic velocity). A Cox multivariate survival mode was constructed to determine the prognostic impact of post-acute, pred-discharge RV dysfunction on all-cause mortality. 615 patients were included: 330 (54%) women, mean age 64 ± 18 years, 265 (43.1%) with post-acute, predischarge RV dysfunction. During follow-up (median 1068 days), 88 (14.3%) patients died. On Cox multivariate analyis, pre-discharge post-acute tricuspid regurgitation systolic velocity emerged as the only independent echocardiographic predictor of mortality (HR 1.73 for every 1 m/s increase; 95% confidence interval 1.033-2.897; p = 0.037). RV dysfunction persists in almost one half of PE patients in the post-acute phase on pre-discharge echocardiography; however, only tricuspid regurgitation systolic velocity independently predicts long-term prognosis.
Kokalj et al. (Thu,) conducted a cohort in Acute low- and intermediate-risk pulmonary embolism (n=615). Tricuspid regurgitation systolic velocity (per 1 m/s increase) vs. Lower tricuspid regurgitation systolic velocity was evaluated on All-cause mortality (HR 1.73, 95% CI 1.033-2.897, p=0.037). Every 1 m/s increase in post-acute, pre-discharge tricuspid regurgitation systolic velocity independently predicted long-term all-cause mortality (HR 1.73) in patients with pulmonary embolism.
