RESUMO
Acute pulmonary embolism (APE) is characterized by numerous clinical manifestations which are the result of a complex interplay between different organs; the symptoms are therefore various and part of a complex clinical picture. For this reason, it may not be easy to make an immediate diagnosis. This is a comprehensive review of the literature on all the various clinical pictures in order to help physicians to promptly recognize this clinical condition, remembering that our leading role as cardiologists depends on and is influenced by our knowledge and working methods.
RESUMO
The exact prevalence of mobile right heart thromboemboli (RHTh) in patients with pulmonary embolism (PE) is unknown, depending upon PE severity and the use of early echocardiography. Similarly, the mortality rate is variable, though RHTh detection appears to substantially increase the risk of death in patients with PE. The aim of this study was to assess the prevalence of RHTh in different risk categories in a wide series of patients with PE, and to analyse the effect of RHTh on in-hospital mortality. Among 1,716 patients enrolled in the Italian Pulmonary Embolism Registry, 1,275 (13.3% at high risk, 59.3% at intermediate risk and 27.4% at low risk) had echocardiography within 48 hours from hospital admission and entered the study. Overall, RHTh were detected in 57 patients (4.5%, at admission echocardiography in 88%): in 27/169 (16%) high-risk, in 29/756 (3.8%) intermediate-risk and 1/350 (0.3%) low-risk patients, respectively. At multivariate analysis, only advanced age (odds ratio [OR] 1.61, 95% confidence [CI] 1.27-2.03, p<0.0001), high-risk category (OR vs low-risk category 37.82, 95% CI 11.26-127.06, p<0.0001) and recurrent PE (OR 45.92, 95%CI 15.19-139.96, p<0.0001) showed a statistically significant effect on mortality. The presence of RHTh significantly increased the risk of dying (OR 3.89, 95%CI 1.98-7.67, p=0.0001) at univariate analysis, but this result was not mantained in the multivariate model (OR 1.64, 95%CI 0.75-3.60, p=0.216). In conclusion, though patients with RHTh had a more severe presentation of PE, this study did not detect an association between RHTh and prognosis.
