Stent restenosis: identifying predictors

Abstract Funding Acknowledgements Type of funding sources: None. Background Despite advancements in stent technology, such as the appearance drug-eluting stents, restenosis remains a common post-procedure complication and is associated with higher morbimortality. These patients frequently need repeat revascularisation pose therapeutic challenge. Purpose This study aims to characterize if it possible identify clinical predictors restenosis. Methods We retrospectively observed population 9815 (D) admitted acute coronary syndrome (ACS) divided them into two groups: those who had (D1), did not (D2). then compared both groups regarding age, sex, personal history smoking (both current or former smokers), hypertension, dyslipidaemia, diabetes mellitus, stroke/TIA, chronic kidney disease location. Results D1 consisted 2,9% population. Both similar age (D1: 67,95±10,35 years vs. D2: 68,56±11,57years) were predominantly male sex (75,9% 73,3%). significantly prevalence (3,1% vs 2,7%, p=0,008; odds ratio: 1,183, 95% CI [1,044;1,340]); dyslipidaemia (72,4% 59,0%, p<0,001; 1,821, [1,586;2,092]); hypertension (86,4% 80,8%, 1,507, [1,259;1,805]); (38,1% 33,6%, p=0,003; 1,215, [1,069;1,381]); (12,1% 10,0%, ratio 1,235, [1,020;1,495]) than D2. When comparing location, was more right artery (4,5% 2,3%, 2,016, [1,775;2,289]), no significant differences relation other segments. There statistically relevant stroke/TIA between groups. Conclusions In ACS, seems be diabetes, disease. Right stenting also rate when revascularised characteristics could help predict which are at risk closer monitoring, potentially improving outcomes. Further developing score these interest.
