摘要
目的 探讨变异型心绞痛(VA)与冠状动脉病变的关系.方法 观察72例VA病人,均采用标准18导联体表心电图检查或进行24小时动态心电图检测,并行冠状动脉造影(CAG)检查,对冠状动脉有无病变及病变特点做以分析.结果 1、72例VA病人中,CAG检查无异常者26例(36.11%),其中心电图评价痉挛部位发生在右冠状动脉(RCA)者20例(76.92%),发生率最高P＜0.05.CAG检查存在固定狭窄者46例(63.89%)其中心电图评价痉挛部位发生在左冠状动脉前降支(LAD)25例(54.35%),发生率最高P＜0.05.2、在CAG检查存在固定狭窄者中狭窄程度＞70%且发生于LAD者12例(48.00%)RCA者6例(50.00%),左冠状动脉回旋支(LCX)者5例(55.56%),并分别与同组比较发生率最高P＜0.05.其中固定狭窄＞70%者3支血管比较LAD发生率最高(52.17%)P＜0.01.结论 1、变异型心绞痛可发生于有狭窄的冠状动脉或正常冠状动脉中,前者多见.2、血管痉挛部位多为LAD及RCA.在冠状动脉无明显病变的VA中,RCA痉挛发生率高于LAD.在存在冠状动脉固定狭窄的VA中,LAD痉挛发生率最高.3、冠状动脉痉挛的发生率与冠状动脉狭窄的程度相关.
Objective To investigate the variant angina(VA) and coronary artery disease relationship.Methods 38 cases of VA patients are using 18-lead ECG or 24-hour Holter monitoring,parallel coronary angiography,coronary artery disease and diseases of whether to do comparative analysis.Results 1,72 cases of VA patients,no abnormal CAG examination of 26 cases(36.11%),ECG evaluation spasm site in the right coronary artery(RCA),20 cases(76.92%),the highest incidence.CAG inspection exist fixed narrow 46 cases(63.89%) of which occurred site ECG evaluation spasm in the left anterior descending coronary artery(LAD) 25 cases(54.35%),the highest incidence.2,there CAG inspection fixed stenosis in the degree of stenosis> 70% occurred in LAD and 12 cases(48.00%) RCA were 6 cases(50.00%),the left circumflex coronary artery(LCX) in 5 patients(55.56%),and compared with the group with the highest incidence of P <0.05.Which fixed stenosis> 70% compared to 3 of the highest incidence LAD(52.17%) P <0.01.Conclusion 1,variant angina can occur in a normal or coronary artery stenosis in the coronary artery,the former seen.2,vasospasm site for more LAD and RCA.No significant coronary artery lesions in the VA,RCA spasm higher incidence of LAD.In the presence of coronary artery stenosis fixed VA,the highest incidence LAD spasm.3,the incidence of coronary artery spasm and coronary stenosis were positively correlated.KeywordsVariant Angina Coronary Spastic stenosisAbstractObjective To investigate the variant angina(VA) and coronary artery disease relationship.Methods 38 cases of VA patients are using 18-lead ECG or 24-hour Holter monitoring,parallel coronary angiography,coronary artery disease and diseases of whether to do comparative analysis.Results 1,72 cases of VA patients,no abnormal CAG examination of 26 cases(36.11%),ECG evaluation spasm site in the right coronary artery(RCA),20 cases(76.92%),the highest incidence.CAG inspection exist fixed narrow 46 cases(63.89%) of which occurred site ECG evaluation spasm in the left anterior descending coronary artery(LAD) 25 cases(54.35%),the highest incidence.2,there CAG inspection fixed stenosis in the degree of stenosis> 70% occurred in LAD and 12 cases(48.00%) RCA were 6 cases(50.00%),the left circumflex coronary artery(LCX) in 5 patients(55.56%),and compared with the group with the highest incidence of P <0.05.Which fixed stenosis> 70% compared to 3 of the highest incidence LAD(52.17%) P <0.01.Conclusion 1,variant angina can occur in a normal or coronary artery stenosis in the coronary artery,the former seen.2,vasospasm site for more LAD and RCA.No significant coronary artery lesions in the VA,RCA spasm higher incidence of LAD.In the presence of coronary artery stenosis fixed VA,the highest incidence LAD spasm.3,the incidence of coronary artery spasm and coronary stenosis were positively correlated.
