Abstract
in English, Portuguese

Background: SARS-CoV-2 is an emerging RNA virus associated with a severe acute respiratory disease known as COVID-19. Although COVID-19 is predominantly a pulmonary disease, some patients have severe cardiovascular damage. We performed a quantitative evidence synthesis of clinical data, myocardial injury biomarkers, and cardiac complications associated with in-hospital death in patients with COVID-19.

Methods: We searched the databases PubMed, Embase, and Google Scholar to identify studies comparing clinical data, myocardial injury biomarkers, and cardiac complications between non-survivors and survivors of COVID-19. Effect sizes were reported as mean difference or standardized mean difference for continuous variables and risk ratio for dichotomous variables with 95% confidence intervals. A random effects model was used to pool the results.

Results: Six retrospective studies reporting data from 1,141 patients (832 survivors and 309 non-survivors) were included. We found that underlying cardiovascular conditions; elevation of high-sensitivity cardiac troponin I, N-terminal pro-B-type natriuretic peptide, and creatine kinase-MB; and cardiac complications were associated with increased risk of death for patients with SARS-CoV-2 infection.

Conclusions: The confirmation that underlying cardiovascular conditions, elevation of myocardial injury biomarkers during COVID-19 infection, and acute cardiovascular decompensation are predictors for mortality in SARS-CoV-2 infection must encourage new research to clarify potential mechanisms and test appropriate treatments.

Fundamento: O SARS-CoV-2 é um vírus de RNA emergente associado à doença respiratória aguda grave conhecida como COVID-19. Embora a COVID-19 seja predominantemente uma doença pulmonar, alguns pacientes apresentam graves danos cardiovasculares. Realizamos uma síntese de evidências quantitativas de dados clínicos, biomarcadores de lesão miocárdica e complicações cardíacas associadas ao óbito hospitalar em pacientes com COVID-19.

Métodos: Buscamos nas bases de dados PubMed, Embase e Google Scholar para identificar estudos que comparassem dados clínicos, biomarcadores de lesão miocárdica e complicações cardíacas entre pacientes sobreviventes e não sobreviventes da COVID-19. Os tamanhos dos efeitos foram apresentados como diferença média ou diferença média padronizada para variáveis contínuas e razão de risco para variáveis dicotômicas, com intervalos de confiança de 95%. Foi utilizado um modelo de efeitos aleatórios para agrupar os resultados.

Resultados: Foram incluídos seis estudos retrospectivos que relataram dados de 1.141 pacientes (832 sobreviventes e 309 não sobreviventes). Verificamos que condições cardiovasculares subjacentes; elevação de troponina cardíaca I de alta sensibilidade; N-terminal do pró-hormônio do peptídeo natriurético do tipo B e creatina quinase-MB; e complicações cardíacas foram associadas ao aumento do risco de óbito em pacientes com infecção por SARS-CoV-2.

Conclusões: A confirmação de que condições cardiovasculares subjacentes, elevação de biomarcadores de lesão miocárdica durante a infecção por COVID-19 e descompensação cardiovascular aguda são preditores de mortalidade na infecção por SARS-CoV-2 deve incentivar novas pesquisas para esclarecer possíveis mecanismos e testar tratamentos adequados.
