ABSTRACT
BACKGROUND:
The treating aims of ST-segment elevation myocardial infarction (STEMI) are vessels recanalization and coronary flow restoration. Coronary slow flow phenomenon (CSFP) is one of the common complications in STEMI patients after percutaneous coronary intervention (PCI) and leads to a higher incidence of adverse clinical outcomes. Alprostadil is a kind of liposomal prostaglandin E1 with beneficial effects on vasodilation, platelet disaggregation and fibrinolysis. But it still remains unclear that whether alprostadil can improve the coronary perfusion in STEMI patients with CSFP after PCI.METHODS:
In this study, a total of 57 STEMI cases with CSFP were included, 28 of which received 2⯵g alprostadil by intracoronary infusion with targeted perfusion microcatheter while the others received 200⯵g nitroglycerin. Coronary angiograms were analyzed by two experienced interventional cardiologists who were blinded to the medicine administration.RESULTS:
We found that compared with nitroglycerin, alprostadil treatment was significantly more effective in increasing the incidence of TFG 3(78.6% vs. 48.3%, Pâ¯=â¯0.021), MBG 3(46.4% vs. 20.7%, Pâ¯=â¯0.039), TMPG 3(53.6% vs. 24.1%, Pâ¯=â¯0.022) and complete STR (42.8% vs. 17.2%, Pâ¯=â¯0.035) and reducing cTFC (28.71 frames vs. 46.03 frames, Pâ¯=â¯0.001). Furthermore, in this study, intracoronary infusion of alprostadil with targeted perfusion microcatheter hardly affected the blood pressure and heart rate of patients, and no threaten complication were observed.CONCLUSIONS:
Alprostadil can effectively alleviate CSFP, which is at the same time secure even for STEMI patients. CLINICAL TRIAL REGISTRATION URL http//www.clinicaltrials.gov. Unique identifier NCT03296670.Key words
