Incidence of acute and subacute complication in primary percutaneous coronary intervention for ST-elevation myocardial infarction in Sunpasitthiprasong hospital: a 5-year retrospective descriptive study.

Abstract

Background: ST-elevation myocardial infarction (STEMI) is one of the major public health problems in Thailand. Mainstay of the treatment of STEMI is reperfusion therapy. Primary percutaneous coronary intervention (PPCI) is the reperfusion strategy of choice because it is associated with a reduced mortality and a lower incidence of complications compared with fibrinolytics therapy. However, various complications in PPCI for STEMI still occur in previous studies.
Material and Methods: The incidence of acute and subacute complications in STEMI patients undergoing PPCI was evaluated. The complications were composite of mechanical complication, bleeding complication, stent thrombosis and contrast-induced nephropathy (CIN).
Results: A total of 804 patients were enrolled in this study. Mechanical complication occurred in 3 patients (0.4%) which all of them were dead from free wall rupture. Bleeding complication occurred in 17 patients (2.1%) which is mainly from gastrointestinal hemorrhage (11 patients, 64.7%). Stent thrombosis occurred in 3 patients (0.4%). CIN occurred in 68 patients (9.8%).
Conclusions: In this study, Incidence of acute and subacute complications in STEMI patients undergoing PPCI are lower than those previously reported. These complications are important problems in improving care of STEMI and basic information for further research.
