Background Adequate sexual knowledge is a key component of cardiac rehabilitation. Sexual knowledge in post-myocardial infarction (MI) patients is unknown. Thus, we conducted this study to investigate the sexual knowledge of post-myocardial infarction patients and their accessibility to sexual counseling. Methodology Between July and September 2018, a cross-sectional survey was carried out in 6six major hospitals in Karachi. The non-probability convenient sampling technique was used to include all patients meeting the inclusion criteria. To reduce biases, face-to-face interviews were conducted by investigators who were trained prior to the start of data collection. Knowledge was assessed using the Swedish version of the "Sex after MI Knowledge Test" questionnaire, where a higher score meant higher knowledge. Data analysis was done using Statistical Package for Social Sciences (SPSS) version 21.0 (IBM Corp., Armonk, NY) The t-test was applied to compare the knowledge score between males and females. Results There was a total of 278 MI patients with a mean age of 54 years, of which 60% were men. The "Sex After MI Knowledge Test" scores varied between 37 and 67 (mean score 51 ± 5). None of the participants obtained the maximum possible test score of 75. The most frequently occurring score was 49 (16%). Around half of the participants (48%) incorrectly believed that sex cannot be safely resumed within a few weeks after the heart attack. Limited knowledge was found in questions pertaining to alcohol, viagra, and late evening being the best time to have sex. Medical knowledge was provided to only 27% (n=76) of the participants, of whom 77% (n=58) received it from the hospital staff itself. A significant difference existed in scores obtained by males and females, with males having a higher score and the mean difference in scores being 1.7 (p=0.015). Conclusion Lack of sexual knowledge in MI patients due to the inadequacy of healthcare providers and the social stigma surrounding the topic causes marital strain leading to low quality of life.
背景 充足的性知识是心脏康复的关键组成部分。心肌梗死（MI）后患者的性知识情况尚不清楚。因此，我们开展了这项研究，以调查心肌梗死后患者的性知识及其获得性咨询的情况。
方法 2018年7月至9月期间，在卡拉奇的6家主要医院进行了一项横断面调查。采用非概率方便抽样技术纳入所有符合纳入标准的患者。为减少偏差，由在数据收集开始前接受过培训的调查人员进行面对面访谈。使用瑞典版的“心肌梗死后性知识测试”问卷评估知识水平，得分越高表明知识水平越高。使用社会科学统计软件包（SPSS）21.0版（IBM公司，纽约州阿蒙克）进行数据分析。应用t检验比较男性和女性的知识得分。
结果 共有278例心肌梗死患者，平均年龄54岁，其中60%为男性。“心肌梗死后性知识测试”得分在37至67分之间（平均得分51±5）。没有参与者获得75分的最高可能测试分数。最常见的分数是49分（16%）。约一半的参与者（48%）错误地认为心脏病发作后几周内不能安全恢复性生活。在与酒精、伟哥以及晚上是最佳性行为时间相关的问题上发现知识有限。只有27%（n = 76）的参与者获得了医学知识，其中77%（n = 58）是从医院工作人员那里获得的。男性和女性获得的分数存在显著差异，男性得分更高，得分平均差异为1.7（p = 0.015）。
结论 由于医疗服务提供者不足以及围绕该主题的社会耻辱感，心肌梗死患者缺乏性知识，导致婚姻关系紧张，生活质量低下。
