RESUMO
Objective To evaluate the clinical and coronary angiographic features of non-Q wave and Q wave myocardial infarction in the elderly. Methods The clinical history(including hypertension and diabetes), complication and in-hospital mortality, blood lipid, serum CK-Mb, LVEF, and the record of the coronary stenosis by angiography 3-4 weeks after infarction were investigated in non-Q wave and Q wave myocardial infarction patients. Results The clinical history and blood lipid did not differ significantly between the NQMI and QMI patients. NQMI patients had a significantly lower maximal peak 〔(68.7?18.6) mmol/L vs (108.6?17.3)mmol/L, P0.05), but occlusion rate of infarct-related vessels in NQMI patients were lower. Conclusions Prognosis of NQMI patients is better than that of QMI patients in acute-phase, and the occlusion rate of infarct-related vessels in NQMI patients were lower.
