High-degree atrioventricular block independently predicted no-reflow (OR 3.127) and was associated with higher in-hospital and long-term mortality in STEMI patients undergoing primary PCI.

Does high-degree atrioventricular block affect the incidence of no-reflow and mortality in patients with STEMI?
This study aims to investigate the mechanistic link between high-degree AV block, the no-reflow phenomenon, and mortality in patients presenting with STEMI.
Effect estimate: OR 3.127 (95% CI 1.215-9.056)
Absolute Event Rate: 23.4% vs 11.7%
p-value: p=0.006
Although it has been established that high-degree atrioventricular block (HAVB) is associated with mortality in the course of ST segment elevation myocardial infarction (STEMI), the mechanisms by which this AV block cause mortality are not yet fully understood. In this study we aimed: (i) to investigate the relationship between HAVB and no-reflow, which has been repeatedly shown to be associated with both short-and long-term mortality; (ii) to determine the effect of both HAVB and no-reflow on in-hospital and long-term mortality.
Çağdaş et al. (Fri,) conducted a cohort in ST-segment elevation myocardial infarction (STEMI) (n=1,217). High-degree atrioventricular block (HAVB) vs. No high-degree atrioventricular block was evaluated on No-reflow phenomenon (OR 3.127, 95% CI 1.215-9.056, p=0.006). High-degree atrioventricular block independently predicted no-reflow (OR 3.127) and was associated with higher in-hospital and long-term mortality in STEMI patients undergoing primary PCI.
