RESUMO
Resumo Fundamento A eficiência do manejo invasivo em pacientes mais velhos (≥75 anos) com infarto do miocárdio sem supradesnivelamento do segmento ST (IAMSSST) permanece ambígua. Objetivos Avaliar a eficiência do tratamento invasivo em pacientes idosos com IAMSSST com base em metanálise e análise sequencial de estudo (TSA). Métodos Ensaios clínicos randomizados relevantes (ECR) e estudos observacionais foram incluídos. Os resultados primários foram morte por todas as causas, infarto do miocárdio, acidente vascular cerebral e hemorragia grave. O odd ratio agrupado (OR) e o intervalo de confiança de 95% (IC) foram calculados. P<0,05 foi considerado estatisticamente significativo. Resultados Cinco ECRs e 22 estudos observacionais com 1.017.374 pacientes foram incluídos.Com base nos resultados de ECR e TSA, o manejo invasivo foi associado a menores riscos de infarto do miocárdio (OR 0,51; 95% IC 0,40-0,65; I2=0%), eventos cardiovasculares adversos maiores (MACE; OR 0,61; 95% IC 0,49-0,77; I2=27,0%) e revascularização (OR 0,29; 95% IC 0,15-0,55; I2=5,3%) em comparação com o tratamento conservador. A combinação de resultados de ECRs e estudos observacionais com ajuste multivariável mostrou riscos consistentemente menores de morte por todas as causas (OR 0,57; IC 95% 0,50-0,64; I2 = 86,4%), infarto do miocárdio (OR 0,63; IC 95% 0,56 -0,71; I2=0%), acidente vascular cerebral (OR 0,59; 95% IC 0,51-0,69; I2=0%) e MACE (OR 0,64; 95% IC 0,54-0,76; I2=43,4%). O melhor prognóstico associado ao manejo invasivo também foi observado em cenários do mundo real. No entanto, para pacientes com idade ≥85 anos, o manejo invasivo pode aumentar o risco de sangramento maior (OR 2,68; IC 95% 1,12-6,42; I2=0%). Conclusões O manejo invasivo foi associado a menores riscos de infarto do miocárdio, MACE e revascularização em pacientes idosos com IAMSSST,no entanto, pode aumentar o risco de sangramento maior em pacientes com idade ≥85 anos.
ABSTRACT
Abstract Background The efficiency of invasive management in older patients (≥75 years) with non-ST-segment elevation myocardial infarction (NSTEMI) remains ambiguous. Objectives To assess the efficiency of invasive management in older patients with NSTEMI based on meta-analysis and trial sequential analysis (TSA). Methods Relevant randomized controlled trials (RCT) and observational studies were included. The primary outcomes were all-cause death, myocardial infarction, stroke, and major bleeding. Pooled odd ratio (OR) and 95% confidence interval (CI) were calculated. P <0.05 was considered statistically significant. Results Five RCTs and 22 observational studies with 1017374 patients were included. Based on RCT and TSA results, invasive management was associated with lower risks of myocardial infarction (OR 0.51; 95% CI 0.40-0.65; I2=0%), major adverse cardiovascular events (MACE; OR 0.61; 95% CI 0.49-0.77; I2=27.0%), and revascularization (OR 0.29; 95% CI 0.15-0.55; I2=5.3%) compared with conservative management. Pooling results from RCTs and observational studies with multivariable adjustment showed consistently lower risks of all-cause death (OR 0.57; 95% CI 0.50-0.64; I2=86.4%), myocardial infarction (OR 0.63; 95% CI 0.56-0.71; I2=0%), stroke (OR 0.59; 95% CI 0.51-0.69; I2=0%), and MACE (OR 0.64; 95% CI 0.54-0.76; I2=43.4%). The better prognosis associated with invasive management was also observed in real-world scenarios. However, for patients aged ≥85 years, invasive management may increase the risk of major bleeding (OR 2.68; 95% CI 1.12-6.42; I2=0%). Conclusions Invasive management was associated with lower risks of myocardial infarction, MACE, and revascularization in older patients with NSTEMI, yet it may increase the risk of major bleeding in patients aged ≥85 years.
