摘要
目的 探讨左冠状动脉主干 (左主干 )狭窄的临床特点、诊断及治疗方法。方法 按冠状动脉造影 (CAG)结果将冠状动脉管径狭窄程度分为轻、中、重及完全闭塞 4组 ,并按其他冠状动脉受累情况分为孤立左主干组 9例 (4 6 2 % )、左主干 +1支组 15例 (7 6 9% )、左主干 +2支组 5 3例(2 7 18% )、左主干 +3支组 118例 (6 0 5 1% )。结果 经CAG确诊的 2 892例冠心病患者中左主干狭窄 195例 (6 74 % ) ,检出率低。临床主要表现为不稳定心绞痛 16 4例 (84 1% ) ,心肌梗死 (MI) 12 5例(6 4 1% )。冠状动脉旁路移植术 (CABG) 5 7例 ,术后 4 7例 (84 2 % )患者心绞痛消失。 5例行无保护性左主干病变直接支架术 ,术后无心绞痛再发。结论 左主干狭窄临床症状严重。CAG是确诊的唯一手段。CABG为最佳治疗方法。无保护性左主干病变直接支架术可用于有适应症患者。
Objective To explore the clinical features diagnosis and treatment of left main coronary artery (LM) disease. Methods According to the results of coronary angiography,significant stenosis was defined as ≥50% stenosis. Isolated LM group had 9 patients (4.62%),one-vessel stenosis LM group 15 patients (7.69%),two-vessel stenosis LM group 53 patients (27.18%) and three-vessel stenosis LM group 118 patients (60.51%). Results 195 cases (6.74%) of LM stenosis were found. The incidence rate was low. 164 patients (84.1%) had unstable angina,and 125 patients (64.1%) had myocardial infarction. Coronary artery bypass surgery was performed in 57 patients (29.2%) and the angina disappeared in most of them (84.2%). Five patients received unprotected LM stenosis and angina disappeared in all. Conclusion LM stenosis has sever symptoms. Coronary angiography is the only way for diagnosis and CABG the best treatment. Unprotected LM stenosis is valuable for some patients.
