Prognostic significance of computed tomography-assessed right ventricular enlargement in low-risk patients with pulmonary embolism: Systematic review and meta-analysis.

BACKGROUND: For patients with acute low-risk pulmonary embolism (PE), determined by a validated clinical prognostic score, the additive prognostic significance of computed tomography (CT)-assessed right ventricular (RV) enlargement is uncertain. METHODS: We performed a systematic review and meta-analysis of studies that enrolled patients with acute low-risk PE to assess the prognostic value of concomitant CT-assessed RV enlargement for 30-day all-cause mortality and PE-related death. We conducted unrestricted searches of PubMed and Embase through December 2019. We used a random-effects model to pool study results; Begg rank correlation method to evaluate for publication bias; and I2 testing to assess for heterogeneity. RESULTS: Of the 7 cohorts with 2197 participants who had low-risk PE and provided results on the primary outcome, 743 (34%; 95% confidence interval [CI], 32-36%) patients had concomitant RV enlargement. Six of 743 (0.8%; 95% CI, 0.3-1.8%) patients with concomitant RV enlargement died 30-days after the diagnosis of PE compared with 3 of 1454 (0.2%, 95% CI, 0-0.6%) without RV enlargement. CT-assessed RV enlargement did not have a significant association with 30-day all-cause mortality (odds ratio [OR], 2.6; 95% CI, 0.7-9.4; I2 = 0%; P = 0.15) or PE-related mortality (OR, 2.8; 95% CI, 0.7-12.1; I2 = 0%; P = 0.16). CONCLUSIONS: CT-assessed RV enlargement occurs in a third of PE patients identified as low-risk by clinical scores. Mortality rate in these patients is low, and CT-assessed RV enlargement was not associated with a significantly increased risk of death within 30 days of PE diagnosis.

Implications of Abnormal Troponin Levels With Normal Right Ventricular Function in Normotensive Patients With Acute Pulmonary Embolism.

Among patients with pulmonary embolism (PE), various permutations of normal or abnormal cardiac troponin results and normal or abnormal echocardiographic right ventricular function are encountered in clinical practice. We aimed to explore whether there is a true gradient of risk based on troponin and echocardiographic results. This study included normotensive patients with PE from the PROgnosTic valuE of CT scan in hemodynamically stable patients with acute symptomatic pulmonary embolism (PROTECT) study. Patients were categorized as having -Troponin/-Echo, -Troponin/+Echo, +Troponin/-Echo, and +Troponin/+Echo. The primary outcome was 30-day "complicated course," including death from any cause, hemodynamic collapse, or recurrent PE. Secondary outcomes included individual adverse event rates. Of the 834 patients who had echocardiographic and troponin results, 569 patients (68%) had -Troponin/-Echo, 126 patients (15%) had -Troponin/+Echo, 74 patients (8.9%) had +Troponin/-Echo, and 65 patients (7.8%) had +Troponin/+Echo. The incidence of 30-day complicated course was 4.6% in patients with -Troponin/-Echo, 11.9% in patients with -Troponin/+Echo, 13.5% in patients with +Troponin/-Echo, and 16.9% in patients with +Troponin/+Echo (P for trend <0.001). In the subgroup of patients with a high-risk sPESI (i.e., intermediate-risk according to the ESC guidelines) (n = 527), the incidence of 30-day complicated course was 14.9% in patients with -Troponin/+Echo, 18.5% in patients with +Troponin/-Echo, and 17.5% in patients with +Troponin/+Echo (P for trend <0.01). In patiens with PE, there seems to be a risk gradient based on troponin and echocardiographic results. This study did not detect a significant risk difference in those with +Troponin/-Echo compared with -Troponin/+Echo.

Outcome of patients with acute symptomatic pulmonary embolism and psychiatric disorders.

OBJECTIVE: To address the association between psychiatric disorders and short-term outcomes after acute symptomatic pulmonary embolism (PE). METHODS: We identified adults with PE enrolled in the RIETE registry between December 1, 2013, and January 31, 2019. Using multinomial regression, we assessed the association between a history of psychiatric disorders and the outcomes of all-cause mortality, PE-related mortality, and venous thromboembolism recurrence and bleeding rates through 30 days after initiation of treatment. We also examined the impact of depression on all-cause and PE-specific mortality. RESULTS: Among 13,120 patients diagnosed with acute PE, 16.1% (2115) had psychiatric disorders and 4.2% died within the first 30-days of follow-up. Patients with psychiatric disorders had increased odds for all-cause (adjusted odds ratio [OR] 1.50; 95% CI, 1.21 to 1.86; P < 0.001) and PE-related mortality (adjusted OR 1.64; 95% CI, 1.09 to 2.48; P = 0.02) compared to those without psychiatric disorders. Multinomial logistic regression showed a non-significant trend toward lower risk of recurrences for patients with psychiatric disorders (adjusted OR 0.49; 95% CI, 0.21 to 1.15; P = 0.10). Psychiatric disorders were not significantly associated with increased odds for major bleeds during follow-up (adjusted OR 1.09; 95% CI, 0.85 to 1.40; P = 0.49). Results were consistent in a sensitivity analysis that only considered patients with a diagnosis of depression. CONCLUSIONS: In patients with acute PE, history of psychiatric disorders might predict all-cause and PE-related death in the ensuing month after diagnosis.

Necesidad de una ecocardiografía transtorácica en pacientes con tromboembolia de pulmón de riesgo bajo: revisión sistemática y metanálisis / Need for Transthoracic Echocardiogram in Patients with Low-Risk Pulmonary Thromboembolism: A Systematic Review and Meta-Analysis

INTRODUCCIÓN: No se ha aclarado completamente si se debería realizar una ecocardiografía a los pacientes con tromboembolia de pulmón (TEP) de riesgo bajo. MÉTODOS: Realizamos un metanálisis de estudios observacionales que incluyeron pacientes con TEP de riesgo bajo para determinar el significado pronóstico de la disfunción ecocardiográfica del ventrículo derecho (VD). El evento primario considerado fue la muerte por cualquier causa a corto plazo. El evento secundario fue la muerte por la propia TEP a corto plazo. Utilizamos un modelo de efectos aleatorios para combinar los resultados, la prueba de correlación de rangos de Begg para estimar el sesgo de publicación y la prueba de la I2 para evaluar la heterogeneidad de los estudios incluidos. RESULTADOS: Identificamos once estudios observacionales que incluyeron 1.868 pacientes con TEP de riesgo bajo. Diez de los 447 (2,2%) pacientes con TEP de riesgo bajo y disfunción del VD fallecieron, comparado con 10 de los 1.421 (0,7%) pacientes sin disfunción del VD. La presencia de disfunción ecocardiográfica del VD no se asoció con la mortalidad precoz por cualquier causa (odds ratio 2,0; intervalo de confianza del 95%, 0,8-5,1, P = 0,14; I2 = 8%), pero se asoció de forma significativa con la muerte por la propia TEP (odds ratio 5,2; intervalo de confianza del 95% 1,7-16, P < 0,01; I2 = 0%). CONCLUSIONES: En pacientes con TEP de riesgo bajo, la disfunción ecocardiográfica del VD no se asocia significativamente a la muerte por cualquier causa pero se asocia de forma significativa a la muerte por la propia TEP

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

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.
