Does conduction delay following acute coronary syndrome worsen short-term outcomes in patients treated with primary percutaneous coronary intervention?
Conduction disturbances following ACS treated with primary PCI are associated with older age, multiple comorbidities, and poorer short-term outcomes.
Background Heart block is an important complication following acute coronary syndrome (ACS) and is usually associated with worse outcomes. The atrioventricular block in the context of inferior infarction is often transient and resolves on its own or shortly after reperfusion. On the other hand, which occurs with anterior infarction is infra-Hisian in most cases and has a worse outcome because of the large area of myocardial necrosis. Aim This study aimed to shed light on these blocks complicating ACS in cases presented to the Cardiology Department of Tanta University Hospital from June 2023 to June 2024. Patients and methods Beginning in June 2023 and continuing until the study’s conclusion, 150 cases of ACS who were hospitalized at Tanta University Hospitals’ Cardiology Department and successfully treated with primary percutaneous coronary intervention will be the subject of this prospective study. Patients will be divided into two groups: group I: patients with conduction delay following ACS ( n =75). Group II: patients without conduction delay following ACS ( n =75). Results The two major findings were: patients with these complications tend to be older and with multiple comorbidities. Patients with these complications had worse outcomes. Conclusion Despite the lower incidence of atrioventricular block and intraventricular conduction delay in the context of ACS at the primary percutaneous coronary intervention era, these conduction disorders remain associated with poorer short-term outcomes.
