Background : High degree atrio-ventricular (AV) block is a common complication in patients with ST elevation myocardial infarction (STEMI). In late presentation STEMI patients (>12 hours onset) with high degree AV block, the effect of percutaneous coronary intervention (PCI) in converting the rhythm and shorten the length of stay is still debatable.

Objective: To assess the effect of PCI on length of stay in late onset STEMI patients with high degree av block.  

Method : We conducted a retrospective cohort study in late onset STEMI patients with high degree AV block during the period of January 2011 until January 2017 in National Cardiovascular Center Harapan Kita. Percutaneous coronary intervention is the independent variable which expected to have an influence on the length of stay. The dependent variable was the length of stay.

Result : There were 91 subjects in this study, that consist of 52 subjects in the percutaneous coronary intervention (PCI) group and 39 subjects in the non PCI group. There were 40 subjects (76,9%) with length of stay ≤ 8 days in PCI group and 9 subjects (23,1%) with length of stay ≤ 8 days in the non PCI group. From multivariate analysis, the significant variables to determine the length of stay were PCI [OR 3,75 (IK 95% 1,06 - 13,26); p value = 0,04], and duration of rhythm conversion [OR 8,83 (IK 95% 2,52 – 30,89); p value = 0,001].

Conclusion : Percutaneous coronary intervention may shortening the length of stay of patients with STEMI (> 12 hours) who had third or second degree type two AV block.

KEYWORDS : percutaneous coronary intervention, high degree AV block, late onset STEMI, length of stay.
