Experimental data and preliminary clinical studies suggest that lipid-lowering drugs might have a beneficial effect on restenosis after coronary angioplasty. Recently, statins have been focused on prevention of restenosis after coronary stent implantation. However, their benefit has not yet been established. The authors studied the effects of statins on stent restenosis. We compared retrospectively the quantitative coronary angiographic (QCA) variables between 62 dyslipidemic patients treated with statins (pravastatin or fluvastatin) and 62 normolipidemic patients, as a control, treated without statins after undergoing successful coronary stent implantation with 6-month follow-up angiography from May 1999 to December 2002. Major cardiac events were about the same in both groups. Each of the QCA variables before and immediately after coronary stenting was similar in the 2 groups. At follow-up angiography, however, minimal lumen diameter (MLD) (2.12 -/+ 0.73 vs 1.78 -/+ 0.7; p < 0.01) was larger in the statin group than in the normolipidemia group. Both restenosis rate (15% vs 31%; p = 0.05) and target lesion revascularization rate (10% vs 24%; p = 0.05) were lower in the statin group than in the normolipidemia group. Statin reduced restenosis rate. The efficacy of statins appears to be dependent on their pleiotropic effects on vascular wall rather than on lipid-lowering effects. 相似文献

The purpose of this study was to know a role of confined placental mosaicism (CPM) in perinatal outcome and postnatal growth and development of infants with intrauterine growth restriction (IUGR). We selected 50 infants with IUGR (<-2.0 SD) from 3,257 deliveries in a regional medical center during the past 10-year period, and carried out cytogenetic and molecular analyses in their placenta and cord blood. Of the 50 infants, 8 had CPM (CPM group) and were composed of five single (CPM2, 7, 13, 22, and 22), one double (CPM7/13), and one quadruple trisomy (CPM2/7/15/20), and one partial monosomy [del(2)(p16)]. The origin of an extra chromosome of trisomy was maternal in six cases of CPM, paternal in one, and undetermined in one. Uniparental disomy in disomic cell lines was ruled out in all these mosaics. We also compared clinical parameters for perinatal outcome between CPM group and infants without evidence of CPM (non-CPM group), such as maternal and gestational age, birth weight, Apgar score, cord blood pH, gender, and uterine artery patterns by Doppler ultrasonography, as well as weight, height, and developmental quotient (DQ) by Denver Developmental Screening Test at age 12 months. Phenotypic abnormalities were noted in two infants with CPM and three infants of non-CPM group: One with CPM22 had ASD and hypospadias, one with CPM7/13 had Russell-Silver syndrome (RSS), and one without CPM had polydactyly, and two without CPM had RSS. All but one infant with CPM are alive at age 12 months. Among the clinical parameters, the detection rate of a notch waveform pattern of the uterine artery was significantly higher in the CPM group (P < 0.05). However, no significant difference was noted in perinatal outcome of pregnancy and in DQ at age 12 months between the two groups. Interestingly, short stature (<-2 SD) at age 12 months was more frequently seen in CPM group (7/8 infants with CPM vs. 8/15 infants without CPM), although no statistically significant difference was obtained. The information obtained will be useful for perinatal care and genetic counseling for infants with IUGR and CPM. 相似文献
