This study examines the prevalence and impact of cardiovascular metabolic diseases on COVID-19 in China. A meta-analysis of six studies involving 1,527 patients found that hypertension, cardio-cerebrovascular disease, and diabetes were prevalent in 17.1%, 16.4%, and 9.7% of COVID-19 cases, respectively. Patients with these comorbidities were more likely to develop severe conditions, with hypertension and cardio-cerebrovascular diseases being significantly higher in ICU/severe cases compared to non-ICU/severe cases. Additionally, at least 8.0% of patients with COVID-19 suffered from acute cardiac injury, which was about 13 times higher in ICU/severe patients. The study concludes that patients with cardiovascular metabolic diseases face a greater risk of severe COVID-19 and that the virus can exacerbate heart damage.This study examines the prevalence and impact of cardiovascular metabolic diseases on COVID-19 in China.
