Ischemic heart disease (IHD), also known as coronary artery disease (CAD), is a leading cause of morbidity and mortality in adults. The aims of this research were to study the recent advances on the prognostic and diagnostic value, drawbacks, and the future directions of cardiac magnetic resonance imaging (CMRI) in the diagnosis of IHD. One hundred patients with IHD who had been clinically diagnosed were enrolled in this study prospectively. CMRI; Siemens Magnetom Sola 1.5 T MRI scanner was used to examine the patients. To confirm the diagnosis, conventional coronary angiography was used. CMRI revealed that the left ventricular (LV) volumes and systolic function of male and female patients differed by age decile were 28.9 ± 3.5%; 32 ± 1.7%, 53.3 ± 11.2; 58 ± 6.6 ml, 100.6 ± 7.1; 98.3 ± 14.7 bpm, 5.4 ± 1.4; 5.8 ± 1.5 L/min, 189 ± 14.3; 180 ± 10.9 ml, and 136 ± 3.1; 123 ± 4.4 ml for the left ventricle ejection fraction (LVEF), stroke volume (SV), heart rate, cardiac output, end diastolic volume (EDV), and end systolic volume (ESV), respectively. CMRI has sensitivity, specificity, and accuracy of 97%, 33.33%, and 95.15%, respectively. Finally, CMRI provides a comprehensive assessment of LV function, myocardial perfusion, and viability, as well as coronary anatomy.
缺血性心脏病（IHD），又称冠状动脉疾病（CAD），是成年人发病率和死亡率的主要原因。本研究旨在探讨心脏磁共振成像（CMRI）在诊断 IHD 中的预后和诊断价值、局限性以及未来方向的最新进展。前瞻性地纳入了 100 例经临床诊断为 IHD 的患者。使用 Siemens Magnetom Sola 1.5T MRI 扫描仪对患者进行 CMRI 检查。为了确诊，采用了常规冠状动脉造影。CMRI 显示，男性和女性患者按年龄十位数划分的左心室（LV）容积和收缩功能分别为 28.9±3.5%；32±1.7%，53.3±11.2%；58±6.6ml，100.6±7.1%；98.3±14.7bpm，5.4±1.4%；5.8±1.5L/min，189±14.3%；180±10.9ml，和 136±3.1%；123±4.4ml 的左心室射血分数（LVEF）、每搏输出量（SV）、心率、心输出量、舒张末期容积（EDV）和收缩末期容积（ESV）。CMRI 的敏感性、特异性和准确性分别为 97%、33.33%和 95.15%。最后，CMRI 可提供 LV 功能、心肌灌注和活力以及冠状动脉解剖结构的全面评估。
