Morphine use and myocardial reperfusion in patients with acute myocardial infarction treated with primary PCI

Background Morphine is frequently used in ST-segment elevation myocardial infarction (STEMI) patients, even if recently it has been associated with a delayed onset of action of the oral antiplatelet agents. There are no data regarding the impact of morphine on myocardial reperfusion after primary percutaneous coronary intervention (PPCI). Objective This study sought to assess myocardial reperfusion by early ST-segment resolution (≥50% at 30...
