摘要: 目的 基于碲锌镉(CZT)心脏专用SPECT机(CZT-SPECT)测定可疑或已确诊冠心病胸痛患者的冠状动脉(冠脉)血流储备(CFR),初步探讨冠脉微血管功能障碍(CMVD)的发生风险及相关危险因素。方法 回顾性分析2021年1月—2021年3月于我院因胸痛行冠脉造影(CAG)及CZT-SPECT检查,且无需血运重建治疗的患者。根据CFR分为CMVD组(55例)和对照组(74例)。比较两组患者的临床特征,初步分析CMVD的相关危险因素。结果 129例患者平均年龄(61.63±9.11)岁,CMVD组共55例,发病率约42.6%。CMVD组BMI、TC、LDL-C、LVEDD、T波倒置比例高于对照组,BMI>24 kg/m2的患者比例高于对照组(78.2%∶54.1%,P<0.05)。两组各支冠脉静息心肌血流量(MBF)无明显差异,而CMVD组负荷MBF明显降低(P<0.01)。经年龄校正,多因素logistic回归分析显示,BMI、LDL-C升高和T波倒置与CMVD独立相关(P<0.05)。结论 在疑诊或确诊冠心病的胸痛患者中,CMVD的发生风险比较高,BMI和LDL-C升高、T波倒置是胸痛患者发生CMVD的独立危险因素。

Abstract: Objective To investigate the risk factors of coronary microvascular dysfunction(CMVD) in patients with chest pain of suspected or confirmed coronary heart disease based on coronary flow reserve(CFR) from zinc-cadmium telluride(CZT-SPECT) special SPECT.Methods A retrospective analysis was performed on 129 patients who underwent coronary angiography(CAG) and CZT-SPECT for chest pain without revascularization at TEDA International Cardiovascular Hospital from January 2021 to March 2021. They were divided into CMVD group(n=55) and control group(n=74) according to CFR. The clinical characteristics of the two groups were compared, and the risk factors related to CMVD were preliminarily analyzed.Results A total of 129 patients was an average age of(61.63±9.11) years. The proportion of BMI, TC, LDL-C, LVEDD and T wave inversion in CMVD group was higher than those in control group. The proportion of patients with BMI>24 kg/m2was higher than the control group(78.2%∶ 54.1%, P < 0.05). There was no significant difference between the two groups in the resting MBF of each branch of the coronary artery, while the CMVD group had a significant decrease in MBF(P < 0.01). After adjusting for age, multivariate Logistic regression analysis showed that increased BMI and LDL-C, T wave inversion were independently associated with CMVD(P < 0.05).Conclusion In patients with chest pain suspected or confirmed coronary heart disease, the risk of CMVD is relatively high. Increased BMI, LDL-C and T wave inversion are independent risk factors of CMVD in patients with chest pain. -
