RESUMO
Objectlves To stuaythe relationship between plasma hemoglobin concentration and estimated glomerular filtration rate (eGFR)in elderly patients with ischemic cardiomyopathy (ICM).Methods Clinical data of patients with coronary heart disease who weredischarged from The First Affiliated Hospital,Chongqing Medicai University between 2005 and 2007 were analyzed retrospectively.Echocardiography resuIts.plasma hemoglobin and creatinine concentration were abstracted from the medical records.The study included235 Chinese Han patients with age 60 years and older with angiography confwmed coronary heart disease.silent myocardial ischemia orangina pectoris,of whom 154 had ICM defined as left ventricular end-diastolic diameter(LVDd),male≥56mm,female≥51 mm(63.51±7.70 mm)measured by M-mode echocardiography.The differences in plasma hemoglobin concentration were analyzed retrospec-were no significant changes in plasma hemoglobin concentration and eGFR;however,plasma hernoglobin concentration was related toeGFR significantly positively in elderly patients with ICM due to coronary heart disease.
