The Myocardial CT Imaging Characteristics of Patients with COVID-19 Combined with Hypertension/ 新型冠状病毒肺炎合并高血压患者心肌CT影像学特点分析

Objective This study was aimed to explore the laboratory and imaging features of myocardial injury in COVID‐19 patients complicated with hypertension Methods The patients with COVID‐19 admitted in Anqing Municipal Hospital from January 22, 2020 to March 4, 2020 were retrospectively analyzed and divided into two groups, according to whether complicated with hypertension or not The relevant laboratory indexes were compared between the two groups during hospitalization, and the related indexes of myocardial injury were compared The corresponding myocardial CT value and EAT volume during hospitalization and before discharge were obtained by CT The characteristics of myocardial imaging in patients with COVID-19 complicated with hypertension were analyzed Results Compared with the general data of the two groups, there were no significant difference in age, gender and the composition of basic diseases between the two groups (P > 0 05) There was no difference in baseline laboratory tests including hs‐TNT between the two groups but the peak value of hs‐TNT in COVID‐19 patients with hypertension was significantly higher than those without hypertension [4 00(3 00,6 00) vs 9 50(6 95,10 45), P = 0 003] Comparing the characteristics of CT, we found that there was no significant difference in myocardial CT value either baseline or before discharge (P > 0 05) There was also no significant difference in baseline EAT volume in two groups (P = 0 176) The EAT volume in the hypertension group was significantly higher than that in the non ‐ hypertension group before discharge (180 09 ± 33 13 vs 114 63 ± 42 30, P < 0 001) While compared with the difference between the discharge‐admission EAT volume changes, we found that EAT volume in the hypertension group significantly increased (59 89 ±24 62 vs 13 43 ±21 18, P = 0 004) Conclusion The peak value of hs‐TNT and the volume of EAT measured by CT in COVID‐19 patients with hypertension were significantly higher than those without hypertension, which suggested that this disease may have potential myocardial injury in patients combined with hypertension
