Filter by:The study aims to compare a preventive percutaneous coronary intervention (PCI) plus optimal medical treatment (OMT) strategy vs. OMT for treatment of non-functionally significant non-culprit lesions presenting with optical coherence tomography (OCT) findings indicative of vulnerable plaque, in patients with ST-elevation myocardial infarction (STEMI) and multivessel disease.
About 200000 cardiac operations are performed in China every year. Cardiopulmonary bypass is the basic strategy of open-heart surgery, which may lead to myocardial ischemia-reperfusion injury and low cardiac output syndrome. It will inevitably affect the patient's postoperative recovery. A number of studies have shown that dexmedetomidine, as an auxiliary sedative, has the effects of inhibiting stress response, antiarrhythmia and cardiac protection.Dexmedetomidine has been widely used in anesthesia in cardiac surgery. However, at present, few clinical studies pay attention to its mechanism. In this study, dexmedetomidine will be used in cardiac surgery with cardiopulmonary bypass to explore the mechanism of cardiac ischemia-reperfusion injury and the protective effect of dexmedetomidine.
Data regarding the safety and efficacy of ivabradine use in severely decompensated HFrEF requiring inotropic support is limited to case series.1 This study aimed to evaluate ivabradine safety and tolerability in admitted cardiogenic shock patients who started on dobutamine infusion for inotropic support.
To determine the effect of exercise training on cardiac outcomes in coronary artery disease patients after Stenting. There is a need to develop strategies, not only to prevent restenosis but also to improve patients' functional status and perception of well-being. In particular, it is not well defined whether exercise training can reduce the restenosis rate and improve the outcome after PCI.
To conduct a quality assurance project to establish the differences in health care processes and cost effectiveness of having the thin-strut Orsiro stent versus the thicker strut Promus stent on the shelf (i.e. as the most accessible stent).
While there are features on a CCTA that are correlated with plaque vulnerability and can be reported on, this is not always done. This is important as it is thought that vulnerable plaques present the greatest risk of myocardial infarction. This study will assess the correlation between software and human classification of these plaques, as well as demonstrating the time efficiency of AI reporting when compared to a clinician.
Introduction. Ischemic cardiomyopathy is one of the death leading causes in industrialized countries. Up-to-date ESC guidelines recommend a surgical approach (coronary by pass graft) in patients with multivessel coronaropathy, with involvement of left main (LM) or proximal left anterior descending (LAD) artery. In any case, is recommended the use of the internal thoracic artery (ITA) as conduct of choice. In consideration of the very strong evidence supporting the use of ITA, the study objective is to analyze and compare some blood markers collected from ITA blood vs. LAD blood, with the purpose of better understanding the technique benefits from a biological point of view, being the hemodynamic one already evident. Methods. Forty patients scheduled for coronary bypass graft (CABG) surgery at the Cardiac Surgery Unit of European Hospital of Rome will be enrolled. Patients which intervention includes off-pump ITA-LAD anastomosis will be included. For each patient blood sample from ITA and LAD will be collected. On those samples, polymorphonuclear leukocytes and platelets activity, endothelial dysfunction, oxidative stress and inflammatory burden will be analysed. In patients in which a pre-operative coronary CT scan is available, findings will be correlated with atherosclerotic plaque morphology. Expected results. Diseased LAD's blood will have a deranged markers profile compared with ITA's, with augmented inflammatory burden, reduce NO availability and increased platelet activation. In the patients subgroup with available coronary CT scan will be possible to esteem the effective blood mixing and speculate on a possible pharmacological effect of CABG, in terms of dilution of inflammatory burden in the target vessel.
This is an retrospective extended study of a randomized clinical trial (The HOST-EXAM trial ClinicalTrials.gov Identifier: NCT02044250). Investigators will perform a retrospective analysis of all participants enrolled in this trial will be performed, until the longest follow-up duration.
The Super Rehab: Can we Achieve Coronary Artery Disease Regression? (a feasibility study) proposes to test the use of a novel lifestyle intervention (Super Rehab), in addition to standard care, for patients with both coronary artery disease and metabolic syndrome. This is a feasibility study that will test study processes, enable optimisation of the intervention and provide data for power calculations to enable design of pivotal trials of the clinical effectiveness of Super Rehab.
The apelin-APJ signaling pathway has emerged as an important novel mediator of cardiovascular control and blood pressure homeostasis. Genetic variation in apelin and its receptors likely contributes to essential hypertension, in addition to a range of traditional risk factors. Thus, a study will be conducted on Syrian patients with hypertension and coronary artery disease to investigate some of the single polymorphisms in the apelin gene and its receptor that may be responsible for the development of these diseases, and to link the levels of this peptide and its receptor in the blood with these polymorphisms and the percentage of these diseases (as shown by many Modern Global Reference Studies).
