Abstract.BACKGROUND:.It is unclear whether more severe coronary atherosclerosis is a prerequisite to an initial acute coronary event in women vs men..HYPOTHESIS:.Women may have more severe coronary atherosclerosis than men in patients with acute coronary event..METHODS:.We used intravascular optical coherence tomography (OCT) to evaluate gender differences in culprit-plaque morphology in patients with a first ST-segment elevation myocardial infarction (STEMI).We retrospectively enrolled 211 consecutive patients who experienced a first STEMI and underwent an OCT examination of their infarct-related artery before primary percutaneous coronary intervention..RESULTS:.Of the 211 patients enrolled, 162 (76.7%) were men and 49 (23.2%) were women. The women were significantly older than the men (mean age, 60.2 ± 8.2 vs 55.7 ± 11.2 years; P = 0.01) and less likely to be current smokers (P = 0.02). Moreover, the delay from symptom onset to reperfusion was longer in women than in men (7.6 ± 6.1 vs 5.5 ± 4.4 hours; P = 0.01). The OCT data indicated that there were no gender differences in culprit-plaque morphology, including lipid length, lipid arc, minimum fibrous cap thickness, or minimum lumen area. Additionally, no gender differences were found in the prevalence of plaque rupture, thin-cap fibroatheroma, residual thrombus, microvessels, macrophages, cholesterol crystals, or calcification..CONCLUSIONS:.Among patients presenting with a first STEMI, there were no differences in culprit plaque features between women and men.
