Myocardial infarction (MI) may decrease sexual function and satisfaction in men and can be influenced by anxiety, depression, and sexual fear. However, few studies have examined short-term changes in sexual function over time in a post-MI population. This study aimed to longitudinally describe changes in sexual function and satisfaction in a sample of men post-MI.
Eighteen patients were recruited from a Midwestern hospital. Surveys were mailed two weeks and three months post discharge. Sexual function was measured with the Male Sexual Function Index. Other variables collected included sexual fear (Multidimensional Sexuality Questionnaire), anxiety and depressive symptoms (Patient-Reported Outcomes Measurement Information System Anxiety and Depression 4a), and use of coping strategies (Coping Strategy Indicator).
Sexual function scores increased in the entire sample from 8.9 (SD 7.3) at two weeks to 14.6 (SD 8.9) at three months (18.8% improvement, 0.04). Men who were sexually active improved their scores by 27.3% (0.01), while those who were not sexually active decreased their scores by 2.3% (0.5). Depressive symptoms and anxiety scores were low and largely stable across timepoints, though there were some improvements among men who were sexually active compared to those who were not. Decreased utilization of avoidance coping strategies was reported in sexually active versus inactive men.
While sexual function improved within a short-time period post discharge among sexually active men post-MI, further research is needed with a larger sample to understand these changes across a longer period. Additional research is also warranted to examine any potential influence of psychosocial predictors.
心肌梗死（MI）可能会降低男性的性功能和性满意度，并且会受到焦虑、抑郁和性恐惧的影响。然而，很少有研究调查过心肌梗死后人群性功能随时间的短期变化。本研究旨在纵向描述心肌梗死后男性样本中性功能和性满意度的变化。
从一家中西部医院招募了18名患者。出院两周和三个月后邮寄调查问卷。使用男性性功能指数测量性功能。收集的其他变量包括性恐惧（多维性问卷）、焦虑和抑郁症状（患者报告结果测量信息系统焦虑和抑郁4a）以及应对策略的使用情况（应对策略指标）。
整个样本的性功能得分从两周时的8.9（标准差7.3）增加到三个月时的14.6（标准差8.9）（改善了18.8%，P = 0.04）。有性生活的男性得分提高了27.3%（P = 0.01），而没有性生活的男性得分下降了2.3%（P = 0.5）。抑郁症状和焦虑得分较低，且在各时间点基本稳定，不过与没有性生活的男性相比，有性生活的男性有一些改善。据报告，有性生活的男性与没有性生活的男性相比，回避应对策略的使用有所减少。
虽然心肌梗死后有性生活的男性在出院后的短时间内性功能有所改善，但需要更大样本的进一步研究来了解更长时期内的这些变化。还需要进行额外的研究来检查心理社会预测因素的任何潜在影响。
