AIM:To examine whether elevated plasma total homocysteine(Hcy) is a risk factor for total ischia burden in angina pectoris.METHODS:The study consisted of 90 cases of stable angina pectoris(SAP) and 90 cases of unstable angina pectoris(UAP) and the difference in total ischia burden was observed between hyperhomocysteinemia(Hhcy) and non-Hhcy in angina pectoris patients.RESULTS:The levels of plasma total Hcy and total ischia burden in UAP were significantly higher than those in SAP(P < 0.05).The total ischia ...
