RESUMO

INTRODUCTION: It is unclear whether low-risk patients with acute symptomatic pulmonary embolism (PE) should undergo echocardiogram. METHODS: We performed a meta-analysis of studies that enrolled patients with acute low-risk PE to assess the prognostic value of echocardiographic diagnosis of right ventricular (RV) dysfunction for the primary outcome of short-term all-cause mortality, and the secondary outcome of short-term PE-related mortality. We used a random-effects model to pool study results, a Begg rank correlation method to evaluate for publication bias, and I2 testing to assess heterogeneity. RESULTS: The meta-analysis included a total of 11 studies 1,868 patients with low-risk PE. Ten of the 447 (2.2%; 1.1%-4.1%) low-risk patients with echocardiographic RV dysfunction died soon after the diagnosis of PE compared with 10 of 1,421 (0.7%; 0.3-1.3%) patients without RV dysfunction. RV dysfunction was not significantly associated with short-term all-cause mortality (odds ratio 2.0; 95% confidence interval, 0.8-5.1, p=.14; I2=8%). RV dysfunction was significantly associated with short-term PE-related mortality (odds ratio 5.2; 95% confidence interval, 1.7-16, p <.01; I2=0%). CONCLUSIONS: In patients with low-risk PE, echocardiographic RV dysfunction is not associated with all-cause mortality, but identifies patients with an increased risk for short-term PE-related mortality.

RESUMO

Limited information exists about the prevalence, management, and outcomes of intermediate-high risk patients with acute pulmonary embolism (PE). In a prospective cohort study, we evaluated consecutive patients with intermediate-high risk PE at a large, tertiary, academic medical center between January 1, 2015 and March 31, 2019. Adjudicated outcomes included PE-related mortality and a complicated course through 30 days after initiation of PE treatment. Repeat systolic blood pressure (SBP), heart rate (HR), brain natriuretic peptide (BNP), and cardiac troponin I (cTnI) measurements, and echocardiography were performed within 48 hours after diagnosis. Among 1,015 normotensive patients with acute PE, 97 (9.6%) had intermediate-high risk PE. A 30-day complicated course and 30-day PE-related mortality occurred in 23 (24%) and 7 patients (7.2%) with intermediate-high risk PE. Seventeen (18%) intermediate-high risk patients received reperfusion therapy. Within 48 hours after initiation of anticoagulation, normalization of SBP, HR, cTnI, BNP, and echocardiography occurred in 82, 86, 78, 72, and 33% of survivors with intermediate-high risk PE who did not receive immediate thrombolysis. A complicated course between day 2 and day 30 after PE diagnosis for the patients who normalized SBP, HR, cTnI, BNP, and echocardiography measured at 48 hours occurred in 2.9, 1.4, 4.5, 3.3, and 14.3%, respectively. Intermediate-high risk PE occurs in approximately one-tenth of patients with acute symptomatic PE, and is associated with high morbidity and mortality. Normalization of HR 48 hours after diagnosis might identify a group of patients with a very low risk of deterioration during the first month of follow-up.

RESUMO

OBJECTIVES: The objective was to assess and compare the accuracy and interobserver reliability of the simplified Pulmonary Embolism Severity Index (sPESI) and the Hestia criteria for predicting short-term mortality in patients with pulmonary embolism (PE). METHODS: This prospective cohort study evaluated consecutive eligible adults with PE diagnosed in the emergency department (ED) at a large, tertiary, academic medical center in the era January 1, 2015, to December 30, 2017. We assessed and compared sPESI and Hestia criteria prognostic accuracy for 30-day all-cause mortality after PE diagnosis and their interobserver reliability for classifying patients as low risk or high risk. Two clinician investigators scored both prediction tools during the ED evaluation. We used the kappa statistic to test for agreement. RESULTS: The 488-patient cohort had a mean (±SD) age of 69.0 (±17.1) years and an approximately even sex distribution. The investigators classified one-quarter of patients as low risk using the sPESI and Hestia criteria (28% vs. 27%, respectively). During the 30-day follow-up, 31 of the 488 (6.4%) patients died. Patients classified as low risk according to the sPESI and the Hestia criteria had a similar 30-day mortality (sPESI 0.7% [1/135], 95% confidence interval [CI] = 0.0%-4.0%; Hestia 2.3% [3/132], 95% CI = 0.5%-6.5%). The two observers had good agreement (κ = 0.80) for the Hestia criteria and very good agreement (κ = 0.97) for the sPESI. CONCLUSION: The sPESI and the Hestia criteria had similar risk classification determination and prognostic accuracy for 30-day mortality after PE. However, the succinct and more objective sPESI had higher interobserver reliability than the Hestia criteria.
