Impact of Congestive Heart Failure and Role of Cardiac Biomarkers in COVID-19 patients: A Systematic Review and Meta-Analysis
Abstract
Importance
Coronavirus disease 2019 (COVID-19) has been reported to cause worse outcomes in patients with underlying cardiovascular disease, especially in patients with acute cardiac injury, which is determined by elevated levels of high-sensitivity troponin. There is paucity of data on the impact of congestive heart failure (CHF) on outcomes in COVID-19 patients.
Objective
To evaluate the occurrence of acute cardiac injury and arrhythmias and to assess the impact of pre-existing CHF and hypertension (HTN) in COVID-19 patients.
Data Sources
We conducted a literature search of PubMed/Medline, EMBASE, and Google Scholar databases from 11/1/2019 till 06/07/2020. databases using following search terms or keywords: “(COVID) AND (Clinical); ((heart) OR (myocard*)) AND (COVID); (COVID) AND (Troponin); (Coronavirus) AND (Heart).”
Study Selection
We identified all relevant studies reporting cardiovascular comorbidities, cardiac biomarkers, disease severity, and survival in COVID-19 patients.
Data Extraction and Synthesis
We followed preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines for abstracting data. Pooled data was meta-analyzed using random-effects model and between-study heterogeneity was calculated with Higgins I2 statistic.
Main outcome and measures
To assess the impact of HTN and CHF and to evaluate different cardiac biomarkers in COVID-19 patients based on their disease severity.
Results
We collected pooled data on 5,967 COVID-19 patients from 20 individual studies. We found that both non-survivors and those with severe disease had an increased risk of acute cardiac injury and cardiac arrhythmias, our pooled relative risk (RR) was — 8.52 (95% CI 3.63– 19.98) (p<0.001); and 3.61 (95% CI 2.03–6.43) (p=0.001), respectively. Mean difference in the levels of Troponin-I, CK-MB, and NT-proBNP was higher in deceased and severely infected patients. The RR of in-hospital mortality was 2.35 (95% CI 1.18–4.70) (p=0.022) and 1.52 (95% CI 1.12–2.05) (p=0.008) among patients who had pre-existing CHF and hypertension, respectively.
Conclusion and Relevance
Cardiac involvement in COVID-19 infection appears to significantly adversely impact patient prognosis and survival. Pre-existence of CHF, and high cardiac biomarkers like NT-pro BNP and CK-MB levels in COVID-19 patients correlates with worse outcomes.
