Values of Coronary Arteriongraphy in Diagnosing Angina / 医学研究杂志

ABSTRACT

Objective To evaluate the value of coronary arteriongraphy(CAG)in diagnosing angina.Methods 219 patients with angina in clinical analysis were selected and divided into 2 groupsthe stable angina(SA)group and unstable angina(UA)group.They all were accepted CAG first time.Then analysis were carried out between clinical diagnosis and results of CAG.Results The total positive rate of CAG in diagnosing angina is 58.90%.The positive rate of SA group(56.52%)shows no significant difference with that of UA group(60.00%).Single vessel lesion and multiple vessels lesion of SA group have little difference,however,the main coronary artery lesions of UA group is single vessel.Conclusions CAG is extremely important in diagnosing angina,but it has its own limit.Experience and new technique should be applied to retrieve locatization of CAG.
