Background Gender-related factors are psycho-socio-cultural characteristics and are associated with adverse clinical outcomes in acute myocardial infarction, independent of sex. Whether sex- and gender-related factors contribute to the substantial heterogeneity in hospital length of stay (LOS) among patients with non-ST-segment-elevation myocardial infarction remains unknown. Methods and Results This observational cohort study combined and analyzed data from the GENESIS-PRAXY (Gender and Sex Determinants of Cardiovascular Disease: From Bench to Beyond Premature Acute Coronary Syndrome study), EVA (Endocrine Vascular Disease Approach study), and VIRGO (Variation in Recovery: Role of Gender on Outcomes of Young AMI [Acute Myocardial Infarction] Patients study) cohorts of adults hospitalized across Canada, the United States, Switzerland, Italy, Spain, and Australia for non-ST-segment-elevation myocardial infarction. In total, 5219 participants were assessed for eligibility. Sixty-three patients were excluded for missing LOS, and 2938 were excluded because of no non-ST-segment-elevation myocardial infarction diagnosis. In total, 2218 participants were analyzed (66% women; mean±SD age, 48.5±7.9 years; 67.8% in the United States). Individuals with longer LOS (51%) were more likely to be White race, were more likely to have diabetes, hypertension, and a lower income, and were less likely to be employed and have completed secondary education. No univariate association between sex and LOS was observed. In the adjusted multivariable model, age (0.62 d/10 y; <0.001), unemployment (0.63 days; =0.01), and some of countries included relative to Canada (Italy, 4.1 days; Spain, 1.7 days; and the United States, -1.0 days; all <0.001) were independently associated with longer LOS. Medical history mediated the effect of employment on LOS. No interaction between sex and employment was observed. Longer LOS was associated with increased 12-month all-cause mortality. Conclusions Older age, unemployment, and country of hospitalization were independent predictors of LOS, regardless of sex. Individuals employed with non-ST-segment-elevation myocardial infarction were more likely to experience shorter LOS. Sociocultural factors represent a potential target for improvement in health care expenditure and resource allocation.
性别相关因素是心理社会文化特征，与急性心肌梗死的不良临床结局有关，而与性别无关。性别相关因素是否导致非 ST 段抬高型心肌梗死患者住院时间（LOS）存在显著异质性尚不清楚。
本观察性队列研究合并分析了来自加拿大、美国、瑞士、意大利、西班牙和澳大利亚的 GENESIS-PRAXY（性别和性决定因素对心血管疾病的影响：从基础到过早急性冠状动脉综合征研究）、EVA（内分泌血管疾病方法研究）和 VIRGO（年轻急性心肌梗死[AMI]患者康复中的性别差异研究）队列中因非 ST 段抬高型心肌梗死住院的成年人的数据。共有 5219 名患者符合入选标准。因 LOS 缺失排除 63 例患者，因无非 ST 段抬高型心肌梗死诊断排除 2938 例患者。最终共分析了 2218 名患者（66%为女性；平均年龄±标准差为 48.5±7.9 岁；67.8%来自美国）。LOS 较长的患者（51%）更有可能为白种人，更有可能患有糖尿病、高血压和较低的收入，且更不可能就业和完成中学教育。未观察到性别与 LOS 之间存在单变量关联。在调整后的多变量模型中，年龄（每增加 10 岁，增加 0.62 天；<0.001）、失业（增加 0.63 天；=0.01）和部分国家（与加拿大相比，意大利增加 4.1 天；西班牙增加 1.7 天；美国减少 1.0 天；均<0.001）与 LOS 延长独立相关。就业对 LOS 的影响可通过医疗史来解释。未观察到性别与就业之间的相互作用。较长的 LOS 与 12 个月全因死亡率的增加相关。
无论性别如何，年龄较大、失业和住院国家都是 LOS 的独立预测因素。患有非 ST 段抬高型心肌梗死并就业的个体更有可能经历较短的 LOS。社会文化因素是改善医疗支出和资源分配的潜在目标。
