Co-morbidity of COVID-19 with cardio-metabolic syndromes
The severity and mortality of COVID-19 infection is positively correlated with the co-morbidity of lung disease, diabetes, cardiovascular diseases, and cerebrovascular diseases. A study reported that 173 patients from 1,099 confirmed cases of COVID-19, had co-morbidities of hypertension (23·7%), diabetes mellitus (16·2%), heart diseases (5·8%), cerebrovascular disease (2·3%), and all of the 173 patients showed severe COVID-19 illness(Guan et al., 2020). Another report showed that of a group of 52 COVID-19 infected patients, 32 patients died with co-morbidities of diabetes (22%) and cerebrovascular diseases (22%)(Yang et al., 2020). Another study reported that of 140 severe cases of COVID-19, about 30% of the patients experienced chronic hypertension, and 12% had diabetes(Zhang et al., 2020a).
