Impact of Prior Digestive System Disease on In-Hospital Gastrointestinal Bleeding in Patients with Acute Myocardial Infarction.

Objective: Patients presenting with acute myocardial infarction (AMI) with prior digestive system disease are more likely to suffer from gastrointestinal (GI) bleeding than those without these diseases. However, few articles reported how the different conditions of the digestive tract produced different risks of GI bleeding.

Reduction in myocardial infarct size by postconditioning in patients after percutaneous coronary intervention.

Background: Postconditioning has been shown to reduce infarct size during reperfusion (< 72 hours). However, it is unknown whether the infarct size reduction with postconditioning is a long-term effect after clinical percutaneous coronary intervention (PCI). The present study tested the hypothesis that postconditioning during primary PCI preserves global cardiac function and reduces infarct size in patients after prolonged reperfusion.
