Filter by:Percutaneous coronary intervention is currently one of the effective methods for the treatment of ACS. Unfortunately, the incidence of ISR is as high as 10%-20% at 3-6 months after PCI. So it is necessary to identify the potential risk factors to provide evidence for the prevention of ISR. Current research shows that anxiety and depression are related to the increased risk of major adverse cardiac events and mortality in patients with acute myocardial infarction. But there remains a relative paucity of evidence for the association between anxiety and depression and in-stent restenosis (ISR) .So a retrospective cohort study was conducted in the first hospital of Qinhuangdao in 2015-2020. The patients who underwent coronary angiography 1 year after PCI in our hospital from January 2015 to September 2020 were selected. Patients were divided into ISR and non-ISR groups depending on the follow-up coronary angiography results. Logistic regression model was utilized for analyzing the association of depression and anxiety with the in-stent restenosis (ISR) after PCI.
Coronary revascularization could be accomplished either by percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG). PCI with drug-eluting stent (DES) implantation is featured by minimal invasive, low complication and rapid rehabilitation. CABG is characterized by improved long-term, event-free survival attributable to the use of left internal mammary artery (LIMA) graft. Hybrid coronary revascularization (HCR) consists of LIMA bypass to left anterior coronary descending artery (LAD) by minimal invasive direct coronary artery bypass (MIDCAB) and PCI of other stenosed coronary arteries with DES implantation. One-step HCR entails LIMA-LAD anastomosis performed through MIDCAB, immediately followed by PCI for non-LAD lesions, sometimes for diagonal branch, in the hybrid operating room. Limited data are available in comparing one-step HCR to PCI alone for the treatment of multivessel coronary artery disease(MVD). The current EAST-HCR study will investigate the efficacy and safety of one-step HCR for patients with MVD, as comparing to PCI alone.
The purpose of this study is to investigate the impact of supraphysiologic oxygen (hyperoxia) on myocardial function in anaesthetized patients undergoing non-cardiac vascular surgery.
The primary aim of this research is to explore the adherence and drop-out from early cardiac rehabilitation (CR), to inform interventions to support patient's adherence to CR and facilitate maintenance. The secondary aim is to understand which aspects of CR are essential for improving health-related quality of life in the short and long-term. This research will comprise four stages adopting a mixed-methods, quasi-experimental, repeated measures design.
Remote Ischemic preconditioning (RIPC) has been reported to improve myocardial microcirculation, promote collateral circulation recruitment, and improve myocardial perfusion in patients.Two large randomized controlled trials demonstrated a perioperative cardioprotective effect of RIPC (reduced troponin levels), but did not find that a single preoperative RIPC improved long-term outcomes of coronary artery bypass grafting(CABG).The effect of a single RIPC before CABG may be too short. This study aims to investigate whether long-term RIPC improved myocardial perfusion in patients 3 months and 6 months after CABG surgery , and to detect changes in blood vascular endothelial growth factor, Nitrc Oxide, adenosine，and Endothelin-1, and to observe MACCE event rates at 12 months.
This is a multi-center, observational cohort study including patients with prior coronary artery bypass grafting (CABG) and ≥1 saphenous vein grafts (SVG) presenting with recurrent ischemic symptoms. Objective: to investigate the clinical outcomes in patients with prior CABG evaluated for bypass graft failure and progression of native coronary artery disease (CAD). Follow-up will be collected through national registry databases, electronic medical patient records and standardized telephonic assessment at 3 and 5 years follow-up.
The purpose of this study is to assess if using the Impella® CP (or Impella® 2.5) device during high-risk PCI in patients with reduced left-sided heart function will result in an improvement in symptoms, heart function and health after a heart procedure compared to the current standard of care.
CONCORD is a prospective observational study evaluating the diagnostic accuracy of cardiovascular magnetic resonance (CMR) and computed tomography with fractional flow reserve (CT-FFR) in patients with suspected coronary artery disease, using invasive fractional flow reserve (FFR) as the reference standard.
People with Coronary Artery Disease (CAD) have narrow or blocked arteries that supply blood to the heart. Reduced blood flow to the heart muscle from CAD can cause chest pain or aching, especially with exercise or activity. CAD can lead to weakening of the heart muscle or heart failure, and a higher risk of heart attack or death. Certain proteins in the blood, known as biomarkers, can be found in people with CAD. Higher levels of these biomarkers are associated with a greater risk of complications from CAD. The purpose of this study is to see if a customized treatment based on biomarkers will reduce the biomarker levels and lead to lower risk of complications from CAD.
Adverse Childhood Experiences (ACEs) are potentially harmful events occurring during childhood that have been associated with chronic physical conditions in adulthood, including coronary artery disease (CAD). ACEs may constitute a portion of the remaining unexplained residual risk for CAD in adults. Identifying a means of addressing these experiences may mitigate their health consequences and result in improved cardiovascular outcomes. The primary objective of this study is to determine if patients who undergo ACE screening experience improved quality of life compared to patients who undergo conventional lifestyle assessment. This will be a single-centre, pragmatic, single-blinded (i.e. data analysts), 1:1, pilot randomized control trial.
