Abstract
En 中文
Despite the importance of comorbid ischemic heart disease (IHD) in the prognosis of asthma, the long-term impact of coronavirus disease 2019 (COVID-19) on IHD in adults with asthma remains unclear. This study investigated the long-term effects of COVID-19 on the risk of IHD in individuals with asthma, particularly regarding COVID-19 severity. Using the Korean National Health Insurance Service claims database, we identified individuals with asthma who had recovered from COVID-19 between October 8, 2020, and December 31, 2021 (n = 8,011) and 1:1 propensity score-matched controls (n = 8,011). The incidence and risk of IHD were compared between the two groups. Overall, during a median follow-up of 95 days (interquartile range, 34-213 days; range, 1-448 days), which includes a median of 14 lag days, the COVID-19 cohort did not show a higher risk of IHD (hazard ratio [HR], 2.11; 95% confidence interval [CI], 0.99-4.48) compared to matched controls. However, when the severity of COVID-19 was considered, the severe COVID-19 cohort exhibited a higher risk of IHD (HR, 4.89; 95% CI, 1.86-12.84) than matched controls; in contrast, the non-severe COVID-19 cohort showed no significantly increased risk of IHD (HR, 1.64; 95% CI, 0.73- 3.70). Severe COVID-19 is associated with an increased long-term risk of IHD in adults with
