Key result
Delayed medical treatment in inferior MI is linked to increased high-degree AV block risk.
Why the study?
The influence of time on development of high degree AV block in inferior MI patients, its association with RV infarction, and related morbidity and mortality were not well defined.
Population
220 patients with inferior MI at NICVD Karachi from October 2006 to March 2007
Comparison
Patients with high degree AV block vs without, and with RV infarction vs without
Design
Prospective descriptive study
Follow-up
4 days hospital course

Prompt treatment may reduce AV block in inferior MI; leaves open whether earlier care improves survival with RV involvement.
Observational (n=220)
No
p-value: p=<0.001
Pirzada et al. (2009) conducted an observational in Acute inferior Myocardial Infarction (n=220). Delayed medical treatment vs. Early medical treatment was evaluated on Development of high degree atrioventricular block (p=<0.001). In patients with acute inferior myocardial infarction, delayed medical treatment was significantly associated with a higher risk of developing high-degree atrioventricular block (p<0.001), which led to high mortality when associated with right ventricular infarction.
