Filter by:This trial will compare the procedural success rate between right and left radial approach in patients undergoing coronary angiography and coronary intervention.
Enrollment: - Patients with stable coronary artery disease (SCAD) and moderate coronary artery stenoses (30-70 %) - Patients with acute myocardial infarction and moderate stenosis of non-culprit arteries (NCL; BYSTANDER LESION) Aims: - To assess the diagnostic accuracy of dobutamine stress echocardiography (DSE) and invasive fractional flow reserve (FFR) measurement - To assess the prognostic impact of reclassification by a mismatching negative test Hypothesis: - DSE and FFR have similar prognostic value in both clinical settings (SCAD and NCL) - Considering the strong negative predictive value of both DSE and FFR, one negative test is sufficiently enough to defer revascularisation, even in the case of mismatch
Congenital heart disease (CHD) is the most common congenital malformations. The right ventricle in the sub-aortic position, or "systemic right ventricle" is one of these complex cardiac diseases. Several studies show that adults with CHD and especially systemic right ventricle have reduced exercise capacity. In addition, studies have shown that there is a correlation between alteration of aerobic physical capacity and alteration of right ventricular systolic function. Understanding and assessing the determinants of the physical capacity of patients with systemic right ventricles and evaluating their quality of life could allows us to improve their therapeutic management and also to expand patient indications to a program cardiac rehabilitation. This can benefit them on their exercise capacity, their tolerance to exercise and their quality of life. The aim is to study the correlation between the quality of life and the aerobic physical fitness of patients with a systemic right ventricle and to determine the clinical and paraclinical parameters that have an impact on the aerobic physical fitness of these patients. The quality of life of patients with a systemic right ventricle will be compared to that of the general population.
The aim of this study is to investigate engagement, motivation, and the barriers to adherence of virtual reality based therapy (VRBT) in patients with cardiac diseases and risk factors to the development of cardiac diseases. In addition, to investigate autonomic and hemodynamic responses of VRBT in comparison with conventional therapy (CT). To do this, patients with cardiac diseases or risk factors will be invited to perform CT or VRBT+CT. They will be submitted to an initial evaluation, and then will be random allocated to 12 weeks of intervention and to a final evaluation. The primary outcomes includes engagement, motivation, barriers and adherence in the 12 previous weeks using questionnaire, after 12 weeks of the intervention and after 12 weeks of the final intervention program. Hemodynamic and autonomic responses will be considered the secondary outcomes being evaluated before, during and after a session at the first, sixth and twelfth week.
To explore predictors of major cardio-vascular events after cardiac surgery and trans-catheter valve implantation with a specific interest in studying mechanisms linking pre-operative leukocyte, fat and myocardial phenotypes with post-intervention outcomes.
Angiography is a common diagnostic and therapeutic procedure in patients with acute coronary syndrome (ACS). The complications are variable between mild self-limited complications to severe life-threatening complications which need early interventions. New angiographic methods are associated with variable complications. Death, myocardial infarction, and stroke are among major angiography complications. In addition, some local complications including bleeding at the site of insertion, infection, arteriovenous fistula, pseudoaneurysm, and thrombosis is reported after angiography. Radial and femoral methods are common angiographic methods. Its shown that radial method is associated with less complications and patients need shorter duration of hospitalization. Radial artery thrombosis is common complication of radial angiography. However, the prevalence is between 5 to 19 percent but often it is not clinically important. Risk of ischemia due to thrombosis is low because of blood flow in radial and ulnar and collaterals. In patients with incomplete palmar arch this is important and may cause ischemia. The aim of this study is to compare the outcomes of coronary angiography using Snuff-box deep palmar arch artery and radial artery in patients attending angiography center of Shahid Mohammadi hospital in Bandar Abbas in 2017.
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.
It is unclear to what extent systemic fluid overload has an impact on T1-mapping results by cardiovascular mangetic resonance imaging. In this study, patients will undergo body composition monitoring assessing systemic fluid overload and T1-mapping using MOLLI by cardiovacular magnetic resonance imaging in order to investigate a possible association with each other.
By bioelectrical impedance spectroscopy (BIS) association of fluid status in patients with valvular heart disease and cardiovascular outcome will be assessed.
The modifications of the medicinal treatments secondary to the hospitalizations have multiple reasons: reassessment of the previous treatment (conciliation), new therapeutic necessities, potential risk of iatrogeny or of drug interaction, restrictions of the therapeutic booklet, classification in reserve or hospital prescription ... These modifications are potentially generating extra costs for the Health Insurance and are monitored under the terms of the Contract of Good Use. The aims of this analysis are to define the medical-pharmaceutical rationale of the treatment changes imposed by hospitalization in a university-hospital center, their influence on the security of the medical treatment of patients and their financial implications for healthcare organizations
