Filter by:The purpose of this study is to evaluate the safety of reducing dual antiplatelet therapy (DAPT) duration to 1 month after implantation of the everolimus-eluting cobalt-chromium stent (CoCr-EES) under the setting of acute coronary syndrome (ACS).
To evaluate the long-term outcome of chronic total occlusion (CTO) patients underwent contemporary percutaneous coronary intervention (PCI) techniques, we design this single-center, large-sample, prospective registry with five-year clinical follow-up, based on the intravascular ultrasound (IVUS) finding.
The objective of CAREBANK study is to establish definitive relationships with human cardiac samples and clinical phenotypes in patients undergoing cardiac procedures. Specifically, the investigators aim at comparing atrial phenotypes from atrial fibrillation patients and controls. The work consists of three broad categories: A) role of atrial cardiomyopathy in atrial fibrillation; B) genetic defects predisposing to atrial fibrillation; and C) the role of inflammation in atrial fibrillation.
This study investigates the effectiveness of a Finnish Tulppa outpatient rehabilitation program. Tulppa is a group-based secondary prevention program for patients with vascular diseases. The program is developed by the Finnish Heart Association. The intervention is implemented at the local primary health care centers in 12 health districts in Finland. A longitudinal controlled study is used to investigate the effects of the intervention on participants' level of cardiovascular risk factors (e.g. lipids, blood pressure, body mass index), functional capacity (e.g. 6 minute walk test), life style as well as psychosocial factors (e.g. smoking, diet, physical activity, health-related quality of life and depression). The data will be collected at baseline (i.e. before the intervention), and 6 and 12 months after the intervention started. The participants (n = 300) are patients diagnosed with coronary heart disease. The study group (n = 150) is recruited from participants of Tulppa rehabilitation in three health care districts (Pirkanmaa, South Karelia, Päijät-Häme). The control group (n = 150) is recruited from two health care districts (Turku and Hyvinkää) that do not provide Tulppa rehabilitation.
Serum uric acid level is a commonly measured biomarker. The association between serum uric acid level and the risk of developing cardiovascular diseases has been observed in some studies, while others showed controversial results. Estimation of this association may help to predict cardiovascular outcomes and may guide new treatment strategies. The hypothesis is that increased serum uric acid level is associated with a range of cardiovascular diseases.
The trial objective is to investigate whether Fractional Flow Reserve (FFR)-Guided Percutaneous Coronary Intervention (PCI) and TransCatheter Aortic Valve Implantation (TAVI) strategy for treatment of multivessel disease and aortic stenosis will be non-inferior to Coronary Artery By-pass Grafting (CABG) and Surgical Aortic Valve Replacement (SAVR) for a composite primary endpoint of all-cause mortality, stroke, myocardial infarction, coronary or valve re-intervention and life-threatening or disabling bleeding at one year.
Fruit and vegetables are a cornerstone of healthy dietary patterns and dietary guidelines worldwide. The supporting evidence, however, is largely derived from observational studies of protective associations with cardiovascular disease (CVD) in health-conscious populations or from randomized trials of the effect of specific fruit or vegetable derived nutrients on CVD risk factors. A growing body of literature has influenced a shift away from a focus on single nutrients to a focus on whole foods and dietary patterns. To what extent fruit and vegetables should contribute to dietary patterns for cardiovascular health and whether specific types of fruit or vegetables should be recommended is unclear. Although previous systematic reviews and meta-analyses have elucidated the association between the intake of total and some specific fruit and vegetables with cardiovascular outcomes, a comprehensive synthesis comparing the certainty of the evidence for the different types of fruit and vegetables in relation to a range of cardiovascular outcomes has yet to be completed. We propose to conduct a systematic review and meta-analysis of the available prospective cohort studies using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to assess the association between different types of fruit and vegetables and different cardiovascular outcomes that include CVD, coronary heart disease [CHD], and stroke incidence and mortality.
It has previously been shown that patients with coronary artery disease may have a harder time quitting smoking if they have a specific genetic profile and that these individuals have a better chance at quitting if they receive nicotine replacement therapy. The investigators hypothesize that determining which individuals with coronary artery disease should receive nicotine replacement therapy based on their genotype may improve the number of individuals who are able to quit smoking.This study randomizes treatment to that determined by the patient's genotype compared to standard, non-genotype-guided, treatment.
The pathogenesis of CHD remains poorly known despite much research over the last few decades. Numerous non-genetic variables have been demonstrated to have a significant impact on the risk of CHD. However, the fact that many individuals with severe CHD do not have any of these non-genetic risk factors supports the notion that genetic factors play a role in the occurrence and progression of CHD. In this study, we investigated the association of polymorphisms affecting Vascular endothelial factors A (VEGFA) and its receptor VEGFR2 (rs3025039, rs699947, rs2305948, rs1870377), CXCR4 (rs2228014), CCR2 (rs1799864), C3 (rs2230199), CCL2 (rs1024611 and rs2857656) and CCL5 (rs2107538 and rs22280789) with CHD susceptibility and the severity of coronary lesion. On another side, clopidogrel is largely prescribed in association with aspirin in order to prevent atherothrombotic complications in patients with acute coronary syndrome. Its effectiveness is undeniably proven by several studies and clinical trials over the years, however, some patients have presented ischemic events such as thrombosis on stent or myocardial infarction despite a well-conducted treatment. This clopidogrel non-responsiveness is probably multifactorial; several genetic and non genetic factors may contribute to impaired platelet inhibition by clopidogrel. In this regard, it is meaningful to determine genetic polymorphisms contributing to the variability of clopidogrel response in patients with Coronary Artery Therefore, the goal of this study is to determine the impact of the polymorphisms, affecting CYP2C19, PON, ABCB1, ITGB3 and P2RY12 genes, on the response to clopidogrel in patients with CAD.Disease (CAD). In fact, the recognition of these factors might predict the exposure to the risk of thrombosis and cardiovascular death in these patients.
The study will evaluate patients with, at least, one previous procedure of coronary revascularization (surgical, percutaneous or both), that are referred for a new, clinically indicated, diagnostic coronary angiography, to describe their clinical characteristics, management, and prognosis, and will propose a prognosis-oriented classification.
