Objective To investigate the prevalence of multidrug and multiple diseases in coronary heart disease in the hospitalized elderly patient.Methods Six hundred and twenty-two hospitalized coronary heart disease patients during 2008-2012 year were assigned to adult coronary heart disease group and they were divided into adults(18-64 years old) and elderly(≥65 years old) groups.Number of drugs was counted and number of diseases was counted based on diagnosis.Multidrug was defined as the kinds of concurrent drug use was over 5.Results The average kinds of drugs used in adult coronary heart disease group was (5.2 ± 3.4).The average kinds of drugs used in elderly coronary heart disease group was (11.2 ± 7.2).The average kinds of drugs in elderly coronary heart disease was higher than that of adult coronary heart disease (t =2.508,P ＜ 0.01).The average types of diseases in elderly coronary heart disease was higher than that of adult groups ((5.1 ±3.1) vs.(8.2 ±4.8),t =2.400,P ＜0.01).Conclusion Multidrug and multiple diseases are prevalent in the hospitalized coronary heart disease patient,and they are more prominent in elderly coronary heart disease patients.It is needed to further optimize the treatment.

Objective To assess the prevalence and risk of coronary artery disease (CAD) in Chinese adults with type 2 diabetes mellitus (T2DM) using electron beam computed tomography (EBCT) and EBCT angiography (EBCTA). Methods: Ninety-four cases were enrolled in this study including diabetes (n=28), impaired glucose tolerance (IGT, n=30), coronary heart disease (CHD, n=11), and control (n=25). Cardiac EBCT plain scanning and EBCTA were performed on all of these subjects to evaluate coronary artery calcification (CAC) scores, and number of segments of stenosed coronary arteries. Both CAC and/or coronary artery stenosis were defined as patients with coronary artery lesions (CAL). Results CAC scores were not different with the control, diabetes, IGT, or CHD (P＞0.05)groups. Compared to control (0.520±1.295), more stenosed coronary arteries segments (P＜0.05) were detected in diabetes (2.964±1.915), IGT (2.200±2.024), and CHD (2.273±1.679). Number of stenosed artery segments were correlated with age (r=0.215, P=0.019),postprandial glucose (r=0.224, P=0.015), total cholesterol (r=0.323, P=0.000), and duration of diabetes (r=0.208, P=0.004). The incidences of CAL in diabetes (96.43%), IGT (93.33%), and CHD (90.91%) was substantially higher than that in normal control (56.00%, P＜0.01).The odds ratio of CAL associated with having diabetes was estimated to be 7.514 (95% CI: 1.885-63.778). Conclusions Coronary artery lesions are prevalent in Chinese adults with type 2 diabetes, implying a high CAD risk. EBCTA holds potential in depicting the details of CAL and can be used to track the progression of CAD in diabetes patients.
