In patients with anterior STEMI and new-onset RBBB, major adverse cardiac events occurred in 45%, with mortality at 32.5%, indicating poor clinical outcomes.
Even in the era of primary PCI, new-onset RBBB in patients with anterior STEMI remains associated with exceptionally high rates of short-term morbidity and mortality.

Background Prior research conducted either before or after thrombolytic therapy revealed that patients with anterior segment elevation myocardial infarction (STEMI) who got either conservative medical treatment or thrombolytic therapy had worse clinical outcomes when they had right bundle branch block (RBBB). Assessing the effect of primary percutaneous coronary intervention on the clinical outcomes of patients who present with anterior STEMI linked to RBBB was the goal of this study. Aim The purpose of this study was to assess the clinical outcomes of patients who received primary percutaneous coronary intervention for an anterior STEMI associated with RBBB during their hospital stay. Patients and methods This study was conducted on 40 patients with anterior STEMI associated with new-onset RBBB who were admitted to the cardiology department at Tanta University hospitals between May and the end of October 2023. Clinical and laboratory assessment as well as echocardiographic evaluation were carried out during the period of hospital stay. Results Most of the patients were males (80%), smoking was the most common risk factor (72.5%) with a great majority of them had multi-vessel disease (62.5%). Major adverse cardiac events occurred in 45% of the study population; congestive heart failure was the most common incident morbidity (45%), and mortality was witnessed in 32.5%. Conclusion Even during the coronary intervention era, recent-onset RBBB was linked to poor clinical outcomes in patients with anterior STEMI.
