Abstract
Background
COVID-19 has resulted in high mortality worldwide. Information regarding cardiac markers for precise risk-stratification is limited. We aim to discover a sensitive and reliable early-warning biomarker for optimizing management and improving the prognosis of COVID-19 patients.
Methods
A total of 2,954 consecutive COVID-19 patients who were receiving treatment from the Wuhan Huoshenshan Hospital in China from February 4 to April 10 were included in this selected retrospectively cohort. Serum levels of cardiac markers were collected after admission. Coronary artery disease diagnosis and survival status were also recorded. Single-cell RNA-sequencing of cells was performed to analyze SARS-CoV-2 receptor expression.
Results
Among 2,954 COVID-19 patients in the final analysis, the median age was 60 years (50–68 years), 1,461 (49.5%) were female, and 1,515 (51.3%) were severe/critical. Compared to mild/moderate (1,439, 48.7%) patients, severe/critical patients showed significantly higher levels of cardiac markers within the first week after admission. In severe/critical COVID-19 patients, those with abnormal serum levels of brain natriuretic peptide (42 [24.6%] vs 7 [1.1%]), hs-TNI (38 [48.1%] vs 6 [1.0%]), α- HBDH (55 [10.4%] vs 2 [0.2%]), CK-MB (45 [36.3%] vs 12 [0.9%]), and LDH (56 [12.5%] vs 1 [0.1%]) had a significantly higher mortality rate compared to patients with normal levels. The same trend was observed in the ICU admission rate. Severe/critical COVID-19 patients with pre-existing coronary artery disease (165/1,155 [10.9%]) had more cases of abnormal brain natriuretic peptide (52 [46.5%] vs 119 [16.5%]), hs-TNI (24 [26.7%] vs 9.6 [%], α- HBDH (86 [55.5%] vs 443 [34.4%]), CK-MB (27 [17.4%] vs 97 [7.5%]), and LDH (65 [41.9%] vs 382 [29.7%]), when compared with those without coronary artery disease. There was enhanced SARS-CoV-2 receptor expression in coronary artery disease compared with healthy controls. From regression analysis, patients with elevated BNP levels were at a higher risk of death (hazards ratio, 1.001 [95% CI, 1.0003–1.002]).
Conclusions
COVID-19 patients with pre-existing coronary artery disease represented a higher abnormal percentage of cardiac markers, accompanied by high mortality and ICU admission rate. Brain natriuretic peptide is an effective biomarker for risk assessment in COVID-19 patients with or without pre-existing CAD.
