Characteristics of myocardial revascularization in patients with acute coronary syndrome in the post-COVID period

Objective: to evaluate the features of myocardial revascularization in patients with acute coronary syndrome (ACS) in the post-COVID period. Material and methods. A total of 114 patients with ACS and a history of new coronavirus infection (NCI) (group 1). The comparison group included 111 patients with ACS without a history of NCI (group 2). All patients in both groups underwent percutaneous transluminal coronary angioplasty (PTCA) with stenting on the first day. Results. A significant difference between the groups was noted in the frequency of PTCA with stenting, taking into account the age aspect: for patients in the age group over 65 years: p=0.031, relative risk (RR) 0.717 ( [95 % confidence intervals — CI 0.518–0.991]). ACS in the post-COVID period was associated with damage to the right coronary artery (p<0.001, RR 1.629 [95 % CI 1.251–2.120]) and statistically significantly increased the risk of developing reperfusion syndrome, namely the occurrence of cardiogenic shock on the operating table (p=0.023, RR 1.553 [95 % CI 1.162–2.075]), AV blocks (p=0.034, RR 1.775 [95 % CI 1.322–2.383]) and bradycardia (p=0.021, RR 1.707 [95 % CI 1.280–2.276]). Conclusion. Patients with ACS in the post-COVID period more often experience manifestations of reperfusion syndrome after revascularization compared to patients without previous NCI.
