Complex Percutaneous coronary intervention (PCI) for the treatment of ischemic heart disease has increased significantly. We aimed to evaluate sex-related differences in patients undergoing complex PCI.
single-center prospective observational study including patients undergoing complex PCI between 2017 and 2023. Baseline and procedural features, and mid-term outcomes were compared according to the gender distribution. The combined primary endpoint included stroke, myocardial infarction, need for a new coronary revascularization, and all-cause mortality. Propensity score (PS) matching with an inverse probability of treatment weight (IPW) approach was used to adjust for differences in baseline characteristics.
1,283 patients were included, 983 (76.6%) male and 300 (23.4%) female. Median follow-up was 2.4 (IQR: 1-3.8) years. There was a higher rate of no-reflow phenomenon (4% vs. 1.8%, = 0.03) among female patients. In the overall cohort, female patients had a greater risk for the combined primary endpoint (HR 1.28, 95% CI: 1.02-1.59). In the matched cohort, female patients exhibited a higher risk for the combined primary endpoint (HR 1.23, 95% CI: 1.06-1.42), as well as for myocardial infarction (HR 1.34, 95% CI 1.03-1.75), and all-cause mortality (HR 1.21, 95% CI 1.02-1.45), and a trend towards a higher risk for the need of a new coronary revascularization (HR 1.22, 95% CI 0.92-1.61).
in a contemporary cohort of patients undergoing complex PCI procedures, female patients are associated with a higher risk of early complications.
用于治疗缺血性心脏病的复杂经皮冠状动脉介入治疗（PCI）显著增加。我们旨在评估接受复杂PCI患者的性别差异。
单中心前瞻性观察性研究，纳入2017年至2023年间接受复杂PCI的患者。根据性别分布比较基线和手术特征以及中期结局。联合主要终点包括中风、心肌梗死、需要进行新的冠状动脉血运重建以及全因死亡率。采用倾向评分（PS）匹配和治疗权重逆概率（IPW）方法来调整基线特征的差异。
共纳入1283例患者，其中男性983例（76.6%），女性300例（23.4%）。中位随访时间为2.4年（四分位间距：1 - 3.8年）。女性患者无复流现象发生率较高（4%对1.8%，P = 0.03）。在整个队列中，女性患者发生联合主要终点的风险更高（风险比[HR] 1.28，95%置信区间[CI]：1.02 - 1.59）。在匹配队列中，女性患者发生联合主要终点的风险更高（HR 1.23，95% CI：1.06 - 1.42），心肌梗死风险（HR 1.34，95% CI 1.03 - 1.75）以及全因死亡率风险（HR 1.21，95% CI 1.02 - 1.45）也更高，并且有进行新的冠状动脉血运重建需求风险更高的趋势（HR 1.22，95% CI 0.92 - 1.61）。
在当代接受复杂PCI手术的患者队列中，女性患者早期并发症风险较高。
