The most distinctive comorbidities of 32 non-survivors from a group of 52 intensive care unit patients with novel coronavirus disease 2019 (COVID-19) in the study by Xiaobo Yang and colleagues were cerebrovascular diseases (22%) and diabetes (22%). Another study included 1099 patients with confirmed COVID-19, of whom 173 had severe disease with comorbidities of hypertension (23·7%), diabetes mellitus (16·2%), coronary heart diseases (5·8%), and cerebrovascular disease (2·3%). In a third study, of 140 patients who were admitted to hospital with COVID-19, 30% had hypertension and 12% had diabetes. Notably, the most frequent comorbidities reported in these three studies of patients with COVID-19 are often treated with angiotensin-converting enzyme (ACE) inhibitors; however, treatment was not assessed in either study.

高血压和糖尿病患者的COVID-19感染风险增加了吗？

杨晓波及其同事在研究中发现，来自52名重症监护病房的2019年新冠状病毒病（COVID-19）的32名非幸存者中最明显的合并症是脑血管疾病（22％）和糖尿病（22％）。另一项研究包括1099例确诊COVID-19的患者，其中173例患有严重疾病，并发高血压（23·7％），糖尿病（16·2％），冠心病（5·8％）和脑血管疾病（2·3％）。在第三项研究中，在140名因COVID-19入院的患者中，有30％患有高血压，而12％患有糖尿病。值得注意的是，在这三项针对COVID-19的患者的研究中，最常见的合并症通常采用血管紧张素转换酶（ACE）抑制剂治疗；然而，两项研究均未评估治疗方案。
