Objective To investigate the correlation of blood lipid metabolism abnormity and other components of metabolic syndrome on angiocardiopathy and cerebrovascular diseases in the elderly people. Methods The clinical data of elderly people, who underwent medical examination during 1996 to 2005 in the General Hospital of PLA, were retrospectively analyzed. Based on the analysis, the co-existence of blood lipid disorders with glucose metabolic abnormity, hypertension and obesity, as well as their influence on cardio-cerebrovascular diseases were further analyzed. Results The prevalence of blood lipid metabolic disturbance was 69.6%, in which the prevalence of hyper-cholesteremia and hyper-triglyceride were 23.6% and 21.7%, respectively. The prevalence of hyper-cholesteremia accompanied by hyper-triglyceride (mixed group) was 19.3%, that of hyper-triglyceride with lower high density lipoprotein cholesterol was 5.03%, while it was 30.4% in the normal group. There was a higher risk of having the above abnormal condition in patients with type 2 diabetes mellitus (T2DM) and obesity, and they were more frequently complicated by hypertension in the hyper-triglyceride group (70.8%). When the patients with lipid metabolic disturbance were complicated by T2DM, hypertension and obesity, the prevalence of cardiovascular or cerebrovascular diseases increased. The prevalence of CHD was higher in the patients with hyper-cholesteremia and hypertension or diabetes, and incidence of both CHD and CVD was higher in the patients with hyper-triglyceride and either one of hypertension, diabetes or obesity. Conclusion There is high prevalence of lipid metabolic disturbance (more than two thirds) and other components of metabolic syndrome, and high risk of suffering from cardiovascular or cerebrovascular diseases in elderly people. The aging patients with hyper-triglyceride are vulnerable to cardiovascular or cerebrovascular diseases, and more attention should be paid in clinical practice in future.

OBJECTIVETo assess the clinical efficacy of retrograde puncture subintimal angioplasty (SIA) for treatment of occlusive diseases in the long segment of the infrapopliteal artery.

METHODSThe clinical data of 50 patients with occlusive diseases in the long segment of the infrapopliteal artery were retrospectively analyzed. The patients were divided into control group (n=25) and study group (n=25) and received antegrade SIA and retrograde puncture SIA with long balloon after the failed antegrade SIA, respectively. The ankle brachial index (ABI) and the temperature of the infrapopliteal skin before and after the operation were compared between the two groups.

RESULTSThe technical success rate was 100% in the 50 patients, who showed obviously improved ischemic symptoms without serious complications. The ABI of the study group increased from 0.31 ± 0.12 before the treatment to 0.47 ± 0.09 at 24 h, 0.56 ± 0.06 at 1 week, 0.63 ± 0.07 at 3 months, 0.58 ± 0.06 at 6 months, and 0.49 ± 0.03 at 12 months after the treatment, and the skin temperature increased from 28.13 ± 2.45 before the operation to 33.87 ± 1.24, 34.16 ± 0.44, 34.19 ± 0.25, 32.45 ± 0.25, and 31.05 ± 0.21 at the corresponding time points after the treatment, respectively, showing significant improvements after the operation (P<0.05). ABI, skin temperature and the patency rate were similar between the two groups at each of the postoperative time points (P>0.05).

CONCLUSIONRetrograde puncture SIA is safe and effective for treatment of arteriosclerosis obliterans in the infrapopliteal arteries with a high clinical success rate and a low complication rate after the failure of antegrade SIA.
