A Pilot Study of Acute Coronary Syndrome Registry Project in Iwate Prefecture

Not Applicable

• Conditions: acute myocardial infarction

• Registration Number: JPRN-UMIN000046643
• Lead Sponsor: Division of Cardiology, Department of Internal Medicine, Iwate Medical University

Brief Summary

The in-hospital mortality of AMI among patients in regional general hospitals was significantly higher than among patients in high-volume hospitals. However, no significant difference in mortality rate was observed among patients with STEMI undergoing primary PCI. Although no significant difference was found in the in-hospital mortality rate of patients with Killip class I STEMI, significantly lower in-hospital mortality rates were observed in patients admitted in high-volume hospitals for Killip II-IV.
