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 — Cl 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% Cl 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% Cl 1.162-2.075]), AV blocks (p=0.034, RR 1.775 [95% Cl 1.322-2.383]) and bradycardia (p=0.021, RR 1.707 [95% Cl 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.
