Sex differences in mortality in stable patients undergoing vasodilator stress cardiovascular magnetic resonance
2021
Abstract Introduction The prognostic value and therapeutic implications of ischemia as derived from vasodilator stress cardiovascular magnetic resonance (CMR) could differ in men and women, but it has not been stablished. Purpose We assessed the influence of the ischemic burden as derived from CMR on the risk of death and the effect of revascularization across sex. Methods We evaluated 6,237 consecutive patients with known or suspected chronic coronary syndrome (CCS). Extensive ischemia was defined as >5 segments with perfusion deficit. Multivariate Cox proportional hazard regression models were used. Results A total of 2,371 (38.0%) patients were women and 583 (9.3%) underwent CMR-r…
Short-term and long-term results of cardiac surgery in elderly and very elderly patients
2011
Objective: Cardiac operations in elderly patients are increasingly frequent and imply major clinical, ethical, and economic issues. Operative and 5-year results of cardiac operations in patients aged 79 years or more are known in limited series, and a debate is ongoing on the appropriateness of selection of patients for surgery. Methods: We retrospectively reviewed our experience in 6802 patients aged 79 years or more who had received a cardiac operation. Surgical candidates were selected according to functional status, crude operative risk, and social context and were managed according to a multimodality protocol. Results: Mean age was 82 years and surgery was nonelective in 1613 cases (23…
Impact of cardiac rehabilitation exercise program on left ventricular diastolic function in coronary artery disease: a pilot study.
2012
Abstract Diastolic dysfunction is common in coronary artery disease (CAD). Exercise-based cardiac rehabilitation (CR) improves survival and quality of life but its effect on diastolic function is unclear. We sought to determine the impact of CR on diastolic function. We conducted a prospective study of CAD patients referred for 3-month outpatient CR, with pre-CR and post-CR echocardiograms. Twenty-five outpatients (age [mean ± SD], 66 ± 11 years; 7 [28 %] women; 22 [88 %] with recent acute coronary syndrome) were recruited upon beginning CR; one patient lacking follow-up was excluded from analysis. Before CR, patients' mean ejection fraction was 61 ± 7 %; regional wall motion score index wa…
Association Between Platelet Endothelial Cellular Adhesion Molecule-1 Polymorphisms and Atherosclerosis: Results of a Study on Patients from Northern…
2010
Adhesion of circulating cells to the arterial surface is among the first detectable events in atherogenesis. Cellular adhesion molecules, expressed by the vascular endothelium and by circulating leukocytes, mediate cell recruitment and their transendothelial migration. Platelet endothelial cellular adhesion molecule-1 (PECAM-1), involved in this migration, has been associated with the development of atherosclerosis. Studies have investigated an association between coronary artery disease (CAD) and single-nucleotide polymorphisms (SNPs) located in functionally important domains of the PECAM-1 gene with inconsistent results. Thus, we have analyzed the distribution of V125L, N563S, and G670R S…
Prognostic implications of dipyridamole cardiac MR imaging: a prospective multicenter registry
2011
Purpose: To evaluate dipyridamole cardiac magnetic resonance (MR) imaging in the prediction of major events (MEs) in patients with ischemic chest pain in a large multicenter registry. Materials and Methods: Institutional ethics committee approval and written informed consent were obtained. A total of 1722 patients who were undergoing cardiac MR imaging for chest pain were included. Wall motion abnormalities (WMAs) at rest, hyperemia perfusion defect (PD), late gadolinium enhancement (LGE), and inducible WMA were analyzed (abnormal if more than one abnormal segment was seen) with the 17-segment model. A cardiac MR categorization was created: category 1, no PD, LGE, or inducible WMA; category…
Effects of aspirin, nimesulide, and SC-560 on vasopressin-induced contraction of human gastroepiploic artery and saphenous vein.
2007
Objective: The present experiments were designed to evaluate differences in the effects of cyclooxygenase (COX)-1 and COX-2 inhibition on contractile responses of human gastroepiploic artery and saphenous vein elicited by vasopressin. Design: Laboratory investigation. Setting: University laboratory. Subjects: Rings of human gastroepiploic artery were obtained from 32 patients undergoing gastrectomy, and rings of saphenous vein were obtained from 30 patients undergoing coronary artery bypass surgery. Interventions: The rings were suspended in organ baths for isometric recording of tension. We studied the responses to vasopressin in the absence and in the presence of either the vasopressin V …
Cholesteryl ester transfer protein activity and cardiovascular events in patients with chronic kidney disease stage V.
2008
Background Patients with chronic kidney disease (CKD) have an increased risk for cardiovascular events (CVE). Uraemic dyslipidaemia, which is characterized by low HDL-cholesterol (HDL-C) and elevated triglycerides' levels, may contribute to this elevated cardiovascular risk. Cholesteryl ester transfer protein (CETP) lowers HDL-C by transferring cholesterol esters to LDL and VLDL particles. We tested the hypothesis that CETP activity is associated with CVE in patients with CKD stage V. Methods We measured CETP activity and cholesterol levels in 69 haemodialysis patients. CVE and death were prospectively assessed over a follow-up period of 48 months. Results CETP activity was negatively corre…
Novel association of the obesity risk-allele near Fas Apoptotic Inhibitory Molecule 2 (FAIM2) gene with heart rate and study of its effects on myocar…
2014
[Background] The Fas apoptotic pathway has been implicated in type 2 diabetes and cardiovascular disease. Although a polymorphism (rs7138803; G > A) near the Fas apoptotic inhibitory molecule 2 (FAIM2) locus has been related to obesity, its association with other cardiovascular risk factors and disease remains uncertain.
Relationship between Low Bone Mineral Density and Fractures with Incident Cardiovascular Disease: A Systematic Review and Meta-analysis
2017
An increasing evidence base suggests that low bone mineral density (BMD) and fractures are associated with cardiovascular disease (CVD). We conducted a systematic review and meta-analysis summarizing the evidence of low BMD and fractures as risk factors for future CVD. Two independent authors searched major databases from inception to August 1, 2016, for longitudinal studies reporting data on CVD incidence (overall and specific CVD) and BMD status and fractures. The association between low BMD, fractures, and CVD across longitudinal studies was explored by calculating pooled adjusted hazard ratios (HRs) ±95% confidence intervals (CIs) with a random-effects meta-analysis. Twenty-eight studie…
Coronary artery disease: seeing or foreseeing?
2013
This editorial refers to ‘Discordance between Framingham Risk Score and atherosclerotic plaque burden’, by A. Pen et al., doi:10.1093/eurheartj/ehs473 The prevention of cardiovascular disease (CVD) has been a major priority and challenge for policy-makers and healthcare workers for at least five decades. In this ‘co-ordinated set of actions, at public and individual level, aimed at eradicating, eliminating, or minimizing the impact of CVDs and their related disability’,1 the capacity to predict the presence of coronary atherosclerosis obviously plays a central role. Studies show that the combination of a few major risk factors is an easily accessible proxy for risk stratification: the Europ…
