    ABSTRACT: It remains unclear whether sirolimus-eluting stents (SES) have an advantage over bare metal stents (BMS) in patients on dialysis. Percutaneous coronary intervention (PCI) using SES was performed in 54 dialysis patients with 69 lesions. A control group for comparison comprised 54 consecutive dialysis patients with 58 lesions who underwent PCI using BMS. Angiographic and clinical follow-ups were scheduled at 9 months. After the procedure, minimum lumen diameter (MLD) was similar between the 2 groups. At follow-up, the SES group had a higher MLD than the BMS group (1.98+/-0.83 mm vs 1.50+/-0.78 mm, p<0.01). In-stent restenosis rate was lower in lesions treated with SES than in those with BMS (22% vs 40%, p=0.048). However, there was no significant difference between the 2 groups for in-segment restenosis (31% vs 43%, p=0.3). During follow-up, there was no significant difference in the incidence of death, myocardial infarction or target lesion revascularization (TLR) (14% vs 21%, p=0.4) between the SES and BMS groups. In this retrospective study, SES, in comparison with BMS, reduced in-stent restenosis in patients on dialysis. However, in-segment restenosis and TLR were not statistically different between lesions treated with SES and those with BMS.

    ABSTRACT: Adiponectin influences insulin sensitivity and lipid oxidation. Because low plasma adiponectin concentrations are suspected to promote atherosclerosis, we retrospectively assessed relationships of plasma adiponectin concentration to characteristics of coronary heart disease (CHD). Japanese men undergoing coronary angiography for CHD (n = 139) were grouped according to serum adiponectin concentration by enzyme-linked immunosorbent assay (low, <4.0; medium, 4.0-8; high, >8.0 microg/mL). Numbers of coronary arteries with at least 50% stenosis were determined. Serum adiponectin concentration correlated positively with age at onset of CHD (r = 0.285, P = .003). Age at CHD onset in the low-adiponectin group was younger than in the medium or high groups. Adiponectin was protective against CHD onset at ages younger than 58 years (relative risk, 0.778; P = .0047). Significantly more arteries were affected in low-adiponectin patients than in the medium or high group (each P < .01). Adiponectin concentration correlated positively with high-density lipoprotein cholesterol concentration and negatively with triglyceride concentration. Only in diabetic patients did serum adiponectin concentration correlate negatively with body mass index. Low plasma adiponectin concentrations were associated with early CHD onset and multiple atherosclerotic lesions in coronary arteries. Thus, adiponectin concentrations may influence risk of CHD and might serve as one of the screening tests facilitating early intervention.
