Procedural and long-term outcomes of stent post dilatation during primary percutaneous coronary interventions

Abstract Background The role of stent post dilatation (SPD) during primary percutaneous intervention (PPCI) is controversial. Currently there are no clear guidelines or consensus regarding when to perform SPD and it left the operator decision. Purpose aim this study was evaluate procedural long terms outcomes PPCI. Methods We collected retrospectively data 614 STEMI patients who presented two tertiary centers one year period. All underwent excluded with cardiogenic shock, prior CABG, severe LM disease. Patients were divided into groups according procedure. Group 1: had included 424 (69.1%). 2: 190 (30.9%). Both well matched regard demographic lesion characteristics. Procedural clinical at collected. Results significantly higher incidence reflow procedure (33.7% in group 1 vs. 21.6% 2, P=0.026), but final TIMI flow similar between groups. Also, significant difference other as dissection, perforation, cardiac death. After follow up reinfarction (5.6% 1.5% P=0.03) more target vessel revascularization (TVR) (16.7% 4.7% 2 P<0.001). There cerebrovascular stroke (CVS), heart failure Conclusion Our shows that PPCI associated an increased risk need for TVR after up. Finally, did not improve Nonetheless, large-scale randomized trials required establish Funding Acknowledgement Type funding sources: None.
