Left ventricular (LV) failure is the main cause of death in thalassemia. Iron overload in patients with thalassemia leads to the formation of oxygen free radicals. Of the various apolipoprotein E (apoE) alleles, apoE4 is the least efficient in conditions of oxidative stress in comparison with apoE2 and apoE3. Our results showed that apoE4 is a genetic risk factor for LV dysfunction in thalassemia. 相似文献

This report aims to compare the researchers?? early experience with the safety, efficacy, short-term outcomes, and complications of patent ductus arteriosus (PDA) stents in neonates having duct-dependent pulmonary circulation with those of surgically created shunts. Between April 2009 and April 2011, 18 infants with duct-dependent pulmonary circulation underwent cardiac catheterization for PDA stenting as the first palliative procedure in a referral center. For comparison, 20 infants who underwent surgical aortopulmonary shunt placement in another center were used. Follow-up assessment included clinical examination, echocardiography, oxygen saturation, and cardiac catheterization studies. Access and stenting for the PDA were successful in 15 patients (83.3?%). The mean procedure time was 58.43?±?41.25?min, and the mean fluoroscopy time was 18.81?±?5.64?min. Three patients (20?%) in the stented group and 6 patients (30?%) in the surgical group died (P?=?0.09). After a 6-month follow-up period, none of the patients had significant stent stenosis requiring reintervention. The oxygen saturation increase did not differ significantly between the two groups either immediately after the procedure or 6?months later (P?>?0.5). The left pulmonary artery diameter, McGoon ratio, and Nakata index did not differ significantly between the two groups (P?>?0.05), but the right pulmonary diameter was larger in the stented group (5.01?±?0.45 vs 4.1?±?0.49?mm; P?=?0.0001). Stenting for the PDA is an appropriate alternative to surgical shunt creation in many patients with duct-dependent circulation. In our sample, the two groups did not differ significantly in terms of outcome or mortality. 相似文献

This study investigates the role of oral sildenafil in decreasing pulmonary pressure after congenital heart surgery. Between September 2002 and September 2004, among a group of postoperative children with large septal defects, moderate to severe pulmonary hypertension [pulmonary artery (PA) to aortic (Ao) pressure ratio of 0.76 +/- 0.17] and systemic desaturation (Ao Sat = 0.89 +/- 0.11), oral sildenafil (0.3 mg x kg(-1), every 3 hours) was administered for a period of 24-48 hours (sildenafil group). These patients were compared to a group of 22 children with similar pathologies who did not receive sildenafil (control group). Postoperative PA pressure (28.61 +/- 7.80 vs 39.40 +/- 10.80 mm Hg) and PA/Ao pressure (0.28 +/- 0.08 vs 0.41 +/- 0.11) were significantly lower in the sildenafil group ( p = 0.001 and 0.001 respectively). Pulmonary hypertensive crisis was detected in 4 patients in the control group, but none in the sildenafil group ( p = 0.02). There was no significant rise in PA pressure following discontinuation of the drug (26.30 +/- 6.66 vs 28.49 +/- 10.93 mm Hg, p = 0.366). No significant complications were noticed regarding sildenafil use. Low doses of oral sildenafil appear to be effective and safe to control postoperative PA pressure in children. Absence of rebound pulmonary hypertension, availability, and low cost of the drug are considered as its major advantages. 相似文献
