对有心绞痛症状CAG血管无狭窄造影剂充盈排空缓慢的19例患者和CAG正常(对照组)21例患者的心电图、心电图运动试验、心脏X片、超声心动图、血脂、吸烟史等进行观察,结果CAG血管无狭窄造影剂充盈排空缓慢的19例中微血管性心绞痛9例(占47.4％),其中合并左室舒张功能障碍者占55.6％,PtfV_1≤-0.02mm·s者占44.4％;高血压性心脏病2例;有较大吸烟量的的健康人8例,占42.1％。提示CAG血管无狭窄造影剂充盈排空缓慢多见于病变较广泛的微血管性心绞痛患者和吸烟量较大的健康人,预示冠脉贮备功能降低和冠脉小血管张力增高。
The electrocardiogram, electrocardiogram exercise test, cardiac X-ray, echocardiography, blood lipids, smoking history and so on were observed in 19 patients with angina pectoris and CAG vascular narrowing contrast agent filled with slow emptying and 21 patients with normal CAG (control group) Nineteen cases (47.4%) of 19 patients with moderate angina pectoris were filled with CAG vascular contrast-free contrast medium. Among them, 55.6% had left ventricular diastolic dysfunction, 44.4% had PtfV_1≤-0.02mm · s, ; 2 cases of hypertensive heart disease; 8 cases of healthy people with a large amount of smoking, accounting for 42.1%. Prompt CAG vascular stenosis contrast agent filling emptying more common in patients with more extensive lesions angina patients and larger smokers healthy, indicating lower coronary artery reserve and coronary small vessel tension increased.
