Stroke | Year: 2012

Background and Purpose-: ANRIL encodes a long antisense noncoding RNA in the INK4 locus. Although ANRIL has been proven to be associated with coronary heart disease, its roles in stroke are inconsistent, and sparse data are available regarding hemorrhagic stroke. Methods-: A Chinese case-control study was conducted, comprising 1657 cases (724 atherothrombosis, 466 lacunar infarction, and 462 hemorrhagic strokes) and 1664 controls. Stroke patients were prospectively followed-up for a median of 4.5 (range, 0.1-6.0) years. Expression of ANRIL transcripts was examined in 42 human atherosclerotic plaques. Results-: After adjustment for vascular risk factors and correction for multiple comparisons, subjects carrying the GG genotype of rs10757278 had 1.47-fold (95% CI, 1.11-1.89; P=0.05) and 1.60-fold (95% CI, 1.16-2.15; P=0.04) increased risk for atherothrombotic and hemorrhagic strokes, respectively. During the follow-up, 317 recurrent strokes and 301 deaths from all causes were documented. Subjects carrying rs10757278GG had higher risk for stroke recurrence (relative risk [RR],1.56; 95% CI,1.15-2.12; P=0.005) and cardiovascular mortality (RR, 2.0; 95% CI, 1.26-3.18; P=0.003), respectively. Rs10757274 was also associated with stroke risk and recurrence. Family history of stroke further increased the stroke risk by 2.37-fold (95% CI, 1.38-4.06; P=0.01) and recurrent stroke risk by 2.45-fold (95% CI, 1.56-3.86; P<0.0001) respectively, when compared with those carrying none of G-alleles and without family history. Finally, rs10757278 was associated with differential expression of the ANRIL transcripts. Conclusions-: Our findings indicated that the ANRIL may serve as a novel genetic marker for the risk of atherothrombotic and hemorrhagic stroke and their recurrence. © 2011 American Heart Association.

Objectives: The aim was to assess the early and mid-term clinical effects of transaortic extended septal myectomy (TAESM) on obstructive hypertrophic cardiomyopathy (HCM) in China. Methods: Ninety-three consecutive patients [57 men; mean age 45.8 ± 13.4 (11-74) years] with obstructive HCM underwent TAESM in Fuwai hospital. Their clinical data were analysed retrospectively. All the patients had drug-refractory symptoms and left ventricular outflow tract (LVOT) obstruction with a resting or physically provoked gradient of ≥50 mmHg. Preoperative transthoracic, intra-operative transoesophageal and postoperative transthoracic echocardiography was performed to assess LVOT gradients, septal thickness, LVOT diameter, mitral valve function, etc. Systolic anterior motion (SAM) of the anterior mitral valve leaflet had been detected in all preoperatively. Results: All the surgical procedures of the 93 patients were technically successful. The average length of postoperative stay was 7.8 ± 3.7 days. The 30-day and in-hospital mortality was 0%. Initial postoperative transoesophageal echocardiography (TEE) demonstrated marked reduction in LVOT gradient (91.76 ± 25.08 to 14.34 ± 13.44 mmHg, P < 0.0005) and significant improvement in mitral regurgitation (MR; P < 0.0005). Concomitant surgical procedures were carried out in 37 (39.8%). Complete atrioventricular block occurred in 3, complete left bundle branch block in 44, intraventricular conduction delay in 18, complete right bundle branch block in 2, transient renal dysfunction in 2 and transient intra-aortic-balloon-pumping was needed in 2. No other complications were observed during hospital stay. During a follow-up of 10.72 ± 11.02 (1-24) months, there were no readmissions or deaths, and all patients subjectively reported an obvious decrease in limiting symptoms and a significant increase in physical ability. At the latest follow-up, the New York Heart Association functional class decreased from 3.09 ± 0.60 (2-4) preoperatively to 1.12 ± 0.32 (1-2) (P < 0.0005); the LVOT gradient remained low at 14.78 ± 14.01 mmHg; MR remained absent (51) or at mild-(41)-to-moderate-(1) levels and SAM resolved completely in 98.9% (92 of 93) patients. Conclusions: TAESM provides excellent relief from LVOT obstruction in HCM patients, with a conspicuous clinical and echocardiographic outcome at early and mid-term follow-up. For obstructive HCM and cardiac comorbidities, concomitant cardiac procedures with TAESM can be performed with low risk and satisfactory results. © The Author 2012.

Genetic factors influence blood pressure (BP) response to the cold pressor test (CPT), which is a phenotype related to hypertension risk. We examined the association between variants of the α-Adducin (ADD1) and guanine nucleotide binding protein (G protein) Β-polypeptide 3 (GNB3) genes and BP response to the CPT. A total of 1998 Han Chinese participants from the Genetic Epidemiology Network of Salt Sensitivity completed the CPT. The area under the curve (AUC) above the baseline BP during the CPT was used to measure the BP response. Twelve single-nucleotide polymorphisms (SNPs) of the ADD1 and GNB3 genes were selected and genotyped. Both single-marker and haplotype association analyses were conducted using linear mixed models. The rs17833172 and rs3775067 SNPs of the ADD1 gene and the rs4963516 SNP of the GNB3 gene were significantly associated with the BP response to CPT, even after adjusting for multiple testing. For the ADD1 gene, the AA genotype of SNP rs17833172 was associated with lower systolic BP (SBP) reactivity (P<0.0001) and faster BP recovery (P=0.0003). The TT genotype of rs3775067 was associated with slower SBP recovery (P=.004). For the GNB3 gene, the C allele of SNP rs4963516 was associated with faster diastolic BP recovery (P=0.002) and smaller overall AUC (P=0.003). Haplotype analysis indicated that the CCGC haplotype of ADD1 constructed by rs1263359, rs3775067, rs4961 and rs4963 was significantly associated with the BP response to CPT. These data suggest that genetic variants of the ADD1 and GNB3 genes may have important roles in BP response to the CPT. Future studies aimed at replicating these novel findings are warranted. © 2012 The Japanese Society of Hypertension. All rights reserved.

Hypertrophic cardiomyopathy is defined as a primary and familial cardiac disorder characterized by heterogeneous expression, unique pathophysiology and considerable diversity in clinical presentation. Clinical diagnosis was mainly based on the performance of ECG. In addition, cardiovascular MRI or ECG plays an important role in the diagnosis. Nevertheless, myocardial radionuclide imaging, which could provide detailed information on myocardial perfusion, metabolism and neurological function, is a valuable method for exploring the inter-relationship between the morphological, pathophysiological and functional changes in hypertrophic cardiomyopathy. It is also helpful in evaluating the effect of transcoronary ethanol septal ablation and prognosis in patients with hypertrophic cardiomyopathy, which suggests that it is an important imaging method in the comprehensive evaluation of hypertrophic cardiomyopathy. © 2013 Wolters Kluwer Health | Lippincott Williams &Wilkins.

Coronary Artery Disease | Year: 2014

Hybrid coronary revascularization intends to combine the durability and survival advantage of the left internal mammary artery to left anterior descending coronary artery graft by a minimally invasive surgical procedure and the interventional therapy for non-left anterior descending coronary artery vessels to achieve complete revascularization. It provides a feasible and attractive alternative to conventional coronary artery bypass grafting and percutaneous coronary intervention to target multivessel coronary artery disease, and advances the individualized, patient-oriented treatment for heart disease. In initial experiences, this new approach has yielded favorable early or midterm results in selected patients with multivessel coronary artery disease. However, available data related to these outcomes following hybrid revascularization are limited to retrospective studies with relatively small sample sizes. In this review, we aim to provide an overview of hybrid revascularization, and discuss appropriate patient selection, procedure techniques, and the main literature pertaining to the hybrid revascularization. © 2014 Wolters Kluwer Health | Lippincott Williams and Wilkins.

Studies have shown inflammation is involved in the development of acute aortic dissection (AAD). The hypothesis that white blood cell count (WBCc) on admission may have an impact on the shortand long-Term outcomes of type A AAD was tested in a large-scale, prospective observational cohort study. From 2008 to 2010, a total of 570 consecutive patients with type A AAD in Fuwai hospital were enrolled and were followed up. Baseline characteristics and WBCc on admission were collected. The primary outcomes were 30-day and long-Term all-cause mortality. During a median of 1.89 years of follow-up, the 30-day and longterm all-cause mortality were 10.7% and 6.5%, respectively. Univariate Cox regression analysis identified admission WBCc as an independent predictor of 30-day mortality when considered as a continuous variable or as a categorical variable using the cutoff of 11.0 ×109 cells/L (all P<0.05). After adjustment for age, sex, C-reactive protein, D-dimer, and surgical intervention, elevated admission WBCc (<11.0×109 cells/ L) remained an independent predictor of 30-day mortality of AAD (hazard ratio=3.31, 95% confidence interval 1.38-7.93, P=0.007). No impact of admission WBCc was observed on the long-Term allcause mortality. In conclusion, elevated admission WBCc may be valuable as a predictor of 30-day mortality, and may be useful in the risk stratification of type A AAD during hospitalization. © 2015 Wolters Kluwer Health, Inc.
