Little is known regarding the outcome of stent thrombosis-related acute coronary syndrome (ST-related ACS) undergoing primary percutaneous coronary intervention. We investigated the clinical characteristics and outcome of ST-related ACS.
Consecutive 79 ST-related ACS (71 patients) among a total of 2,117 ACS (1,993 patients, 69.6 ± 12.3 years old, male 72.1%) from January 2008 to June 2016 in our hospital were enrolled.
In-hospital mortality of ST-related ACS and Non-ST-related ACS was 7.0% and 4.2%, respectively (P=0.25). Clinical characteristics according to the timing of ST are shown in the table. Cumulative incidence of all-cause death according to the timing of ST and according to implanted stent type is shown (Figure 1 and 2).
These results demonstrated early ST-related ACS exhibits worse outcome with more prior ACS, frequent ST-elevation myocardial infarction and low PCI success rate.
