摘要: 目的 采用心脏磁共振(CMR)综合评估艾滋病患者心肌组织和心功能改变。方法 前瞻性纳入2020年7月至2021年6月在成都市公共卫生临床医疗中心治疗男性45例AIDS患者及匹配的18例正常对照组进行CMR增强扫描,对图像资料进行后处理分析,评估包括水肿、微循环障碍及纤维化在内的心肌组织改变;包括容积参数、射血分数、左心室重构指数(LVRI)在内的心功能指标;包括二尖瓣和三尖瓣结构和功能改变;并进一步比较艾滋病合并/未合并心脏受累与正常对照组的心功能指标。结果 16例(35.5%)的艾滋患者出现包括左右心室收缩功能减低、心肌水肿、二尖瓣及三尖瓣瓣膜增厚、三尖瓣反流、心肌微循环障碍在内的心脏受累表现。与正常对照组相比,合并及未合并心脏受累的艾滋病患者左右心室容积参数均未见明显减低(均P>0.05);而合并心脏受累组左心室射血分数及左心室搏出量较未合并心脏受累组及正常对照组表现出减低趋势。此外,未合并心脏受累组左心室重构指数较正常对照组明显升高[(1.62±0.26)比(1.45±0.24), P=0.025],而合并心脏受累组LVRI较正常对照组未见明显增高。结论 艾滋病患者心脏并发症较常见,包括瓣膜改变、心脏收缩功能减低、心肌水肿及微循环障碍等,在早期左右心室容积参数、射血分数尚未发生明显改变时,艾滋病患者已经发生左心室重构(LVRI改变),CMR能为早期评估艾滋病患者的亚临床心肌损伤提供客观证据。

Abstract: Objective To evaluate the changes of myocardial tissue and cardiac function in AIDS patients by cardiac magnetic resonance imaging (CMR). Method 45 male AIDS patients and 18 healthy controls were prospectively included for CMR scanning. Post-processing analysis was performed to evaluate cardiac involvement. Myocardial tissue changes, including edema, microcirculation disorders and fibrosis; including cardiac function indexes, volume parameters, ejection fraction and left ventricular remodeling index (LVRI); Changes in mitral and tricuspid valve structure and function were assessed. Furthermore, the cardiac function indexes of AIDS patients with/without heart involvement and normal controls were compared. Result 16 cases (35.5%) of AIDS patients presented with cardiac involvement, including reduced systolic function of left and right ventricles, myocardial edema, the mitral and tricuspid valves thickened, triapphal regurgitation and myocardial microcirculation disturbance. There was no significant reduction in left and right ventricular volume parameters in AIDS patients with/without cardiac involvement compared with normal controls (all P>0.05). The left ventricular ejection fraction and left ventricular stroke volume of AIDS patients with heart involvement showed a decreasing trend compared with AIDS patients without heart involvement and normal control. The left ventricular remodeling index of AIDS patients without heart involvement was significantly higher than that of the normal control (1.62±0.26 vs 1.45±0.24, P=0.025), and the LVRI of AIDS patients with heart involvement was not significantly higher than that of the normal control. Conclusion Cardiac involvement in patients with HIV/AIDS is common, such as changes in valves, cardiac dysfunction, myocardial edema and microcirculation, etc. HIV/AIDS patients have developed left ventricular remodeling when the left ventricular volume and ejection fraction has not significantly change in the early stage. CMR could provide more comprehensive objective evidence for assessing myocardial injury of AIDS patients in the early stage.
