Probability of applying temporary cardiac pacing during percutaneous coronary intervention for acute myocardial infarction

Objective:To observe the probability of temporary cardiac pacing during emergency percutaneous coronary intervention (PCI) for acute ST elevation myocardial infarction (STEMI) patients. Methods: A total of 197 consecutive STEMI patients were randomly assigned for study. Patients undergoing emergency PCI in 4 h were assigned to group A(53 cases), the patients undergoing emergency PCI in 4-12 h were assigned to group B(144 cases). Compared the difference for applying temporary cardiac pacing between the two groups. Results: Baseline characteristics and angiographic characteristics showed no significant difference between the two groups (P0.05). The proportion called for temporary cardiac pacing in group A was significantly higher than that of group B (41.5% vs. 23.6%, P0.05). Conclusion: The result suggests for acute myocardial infarction patients who undergo emergency percutaneaus coronary intervention especially in 4 h must preparation cardiac pacing pipe, when cardiac pacing indications occur may promptly carry out temporary cardiac pacing.
