Myocardial Infarction With Non-Obstructive Coronary Arteries in the Greek Population
Acute Myocardial InfarctionNon-Obstructive Coronary Atherosclerosis3 moreThe MINOCA-GR registry will be the first nationwide study aiming to obtain data regarding prevalence, demographics, clinical profile, previous anginal status, presence of cardiovascular risk factors, management and outcomes in patients with Myocardial Infarction with Non-Obstructive Coronary Arteries. An additional purpose of the registry is to highlight, for the first time worldwide to the best of the investigator's knowledge, the role of cardiac computed tomography angiography for risk stratification and personalized therapeutic approach in MINOCA patients.
The MyoVista Angiography Angioplasty Percutaneous Coronary Intervention Trial
Coronary Artery DiseaseDiastolic DysfunctionPurpose of this clinical investigation: clinical evaluation/accuracy of HeartSciences MyoVista High-Sensitivity (hsECG) 12 lead Electrocardiogram device, for patients presenting with cardiac related chest pain and/or Non ST-segment Elevation Myocardial Infarction (NSTEMI). To assess the early intervention of N-STEMI patients. Determine if clinical outcomes can be improved. Assessment will be made on the MYOVISTA's indices, numerical values, and sensitivity/specificity for early detection of cardiac dysfunction/disease,i.e. Coronary Artery Disease (CAD). Primary objective to ascertain efficacy of the MyoVista and evaluate its usefulness in expediting patients that require further investigation/procedure by way of angiography, thus improving the patient care pathway. Recruitment will take place at the Royal Cornwall Hospitals Trust, the Sponsor who will fund the research. A single centre study. Participants will undergo a 12 lead MyoVista ECG in addition to a standard 12 lead ECG. This is not an invasive procedure and carries no risk to the patient. There will be no change in the patient care pathway. The study will last c. 2 years, enrolment of patients ceasing once the statistically significant number to power the study has been met which is sufficient and ethical. Prerequisites for inclusion to the clinical investigation include: Signed informed consent prior to any procedure relating to the investigation Patient compliance with the clinical investigational plan Follow-up appointment(s) attendance Patient(s) presenting to hospital with a clinical diagnosis of Non ST-segment Elevation Myocardial Infarction Notable Electrocardiogram morphological changes, consistent with Myocardial Ischaemia (MI) i.e. T-wave inversion, Biphasic T-wave, ST-segment depression Symptom onset of <12 hrs Elevated High Sensitivity Troponin Score GRACE score of >140 It is hoped that > 75% of patients seen will show willingness and compliance throughout the duration of the clinical investigation. Clinical benefits, early diagnosis of heart disease, streamlined triage of patients, reduction in morbidity/mortality, reduction in costs to National Health Service (NHS) and improved patient centered care.
Study of Hepatitis Eradication Receiving Protease Inhibitor Administration
Coronary Artery DiseaseMoralityThis is a prospective, non-blinded cohort study that will assess the safety, tolerability, and antiviral efficacy of glecaprevir/pibrentasivir therapy given post-discharge to HCV-negative recipients of HCV infected donors. Patients who meet entry criteria will be enrolled while on the transplant waitlist. At the time of transplant, some donors will be HCV positive / NAT positive and some will not be infected. Enrolled patients who receive an HCV negative donor will serve as contemporaneous controls. All study subjects who receive an HCV positive organ will be confirmed to have acquired HCV infection and genotype will be assessed prior to treatment with therapy.
Impact of Mitral Regurgitation on Coronary Haemodynamics and Instantaneous Effect of Transcatheter...
Mitral Valve InsufficiencyCoronary Stenosis2 moreIn the present study, the investigators aim to use the in-vivo Transcatheter Mitral Valve Repair (TMVR) model to determine how Mitral Regurgitation (MR) affects coronary hemodynamics in patients affected with severe MR and concomittant angiographically-documented coronary artery disease. The investigators will also provide unique physiologic data on the acute effect of TMVR using the MitraClip system on coronary microcirculation in patients with severe MR.

Coronary Artery DiseaseAtrial Fibrillation (AF)Information gathered from the patients via a disease specific questionnaire will be married to data from the National Cardiovascular Data Registry (NCDR®). Details will be continuously analyzed and used to direct quality of care at our center. The institution is categorized as a low-volume institution for percutaneous coronary intervention (PCI) for coronary artery disease treatment as well as surgical and endocardial ablation for the management of atrial fibrillation (Afib). The association between operator volume and quality has primarily focused on rare complications, such as mortality. The aim is to highlight the advantages of receiving care close to home. A benefit of offering the procedures to treat diseases at centers that have lower volumes is to improve patients' outcomes while also providing more convenient access to quality care. The key outcome from the patients' experience is alleviation of their symptoms while increasing function and quality of life. To date, there have been no studies documenting the health status benefits of PCI and surgical / endocardial ablation for coronary artery disease and Afib, respectively with low- volume operators. In this study, the investigators sought to examine the feasibility of implementing patient-reported outcomes into clinical care and to demonstrate evidence of benefits, from patients' perspectives, of receiving treatment by low-volume operators.
Safety and Efficacy of DCB Therapy for de Novo Lesions Under the Guidance of QFR in CHD Patients...
Coronary Heart DiseaseSince Gruntzig successfully performed percutaneous coronary balloon angioplasty in 1977, percutaneous coronary intervention has developed rapidly. From bare metal stents to drug-eluting stents (DES), the symptoms and prognosis of patients with coronary heart disease (CHD) have been greatly improved. Although DES has reduced the probability of in-stent restenosis (ISR) and thrombosis compared with BMS since its clinical application, it can not completely solve this problem. Even if the new generation of DES requires revascularization, the incidence of ISR is still as high as 5%-10%. DES treatment is associated with delayed endothelial healing, late acquired poor stent adherence and new atherosclerosis, which lead to late ISR and thrombosis. In addition, DES is still not ideal for the treatment of small vessel disease, diffuse long lesion and bifurcation lesion. Therefore, drug coated balloon (DCB) has attracted people's attention. Balloon-loaded antiproliferative drugs can fully release the drugs to the vascular wall during balloon dilation, which can inhibit the restenosis process from the beginning of injury, and show good efficacy and safety in some specific lesions. Many clinical studies have shown that DCB has good efficacy and safety in some specific lesions (ISR, small vessel disease, bifurcation disease, in situ lesion). Especially in the treatment of ISR, researchers believe that its efficacy is not inferior to DES, and it has the advantage of non-metal residues. Quantitative flow ratio (QFR) is the second generation FFR detection method based on angiographic images. The diagnostic accuracy of QFR 0.80 for myocardial ischemic stenosis was 92.7%. Compared with QCA, the positive predictive value and negative predictive value of QFR were also significantly better than those of QCA. The latest FAVOR II results also confirm that QFR is more sensitive and specific in diagnosing myocardial ischemia caused by coronary artery stenosis than QCA, and confirm the feasibility of using QFR online in catheter lab to evaluate the functional significance of coronary artery critical lesions. However, there is no report on the treatment of de novo lesions in patients with coronary heart disease by DCB under the guidance of QFR. The aim of this study was to evaluate the safety and efficacy of drug balloon therapy for de novo lesions in patients with CHD under the guidance of QFR compared with DES implantation.
