RESUMO

Among patients with acute pulmonary embolism (PE), abnormal cardiac biomarkers and elevated right ventricular to left ventricular (RV/LV) diameter ratio are associated with increased morbidity and mortality. However, subjects with baseline heart failure (HF) have abnormalities in cardiac chamber dimensions and biomarkers. We sought to describe risk stratification variables in a cohort with acute PE and categorized HF status as no HF, HF with reduced ejection fraction (HFrEF), or HF with preserved ejection fraction (HFpEF). In total, 182 subjects were identified for this study, of whom 142 were categorized as having no HF, 16 as having HFrEF, and 24 as having HFpEF. The median age was 65 years [interquartile range 51 to 75 years], and 43% were male. Subjects with HFrEF had significantly greater LV diameters and significantly lower RV/LV diameter ratio (no HF 0.94, HFrEF 0.65, HFpEF 0.89, p = 0.002). Subjects with HFrEF also had significantly higher B-type natriuretic peptide levels (no HF 112 pg/mL, HFrEF 835 pg/mL, HFpEF 241 pg/mL, p <0.001) and higher 90-day mortality rates. Among subjects with acute PE, those with baseline HFrEF had significantly greater LV diameter and lower RV/LV diameter ratio than those of patients with HFpEF or no HF. In addition, subjects with HFrEF had significantly higher B-type natriuretic peptide levels and worse survival at 90 days. In conclusion, these results indicate that PE risk stratification using current guidelines, especially reliance on RV/LV ratio, is inaccurate among subjects with baseline HFrEF.
