iCorMicA - Stratified Medicine in Angina

The iCorMicA study is a multicentre, prospective, randomised, double-blind, sham-controlled, parallel-group, end-point trial and registry. The investigators seek to determine whether stratified medical therapy guided by an adjunctive interventional diagnostic procedure (IDP) during the invasive management of patients with known or suspected angina but no obstructive coronary artery disease improves symptoms, wellbeing, cardiovascular risk and clinical outcomes.

Machine Learning in Quantitative Stress Echocardiography

Greater diagnostic accuracy is required to find out who is at risk of a heart attack as this can reduce the requirement of more invasive downstream tests and thereby improve the patient experience and also reduce their exposure to risk. Stress echocardiography is a routine clinical test that involves using ultrasound to image the heart whilst it is under stress to assess the risk of a heart attack. This study will focus on developing more accurate analysis tools to interpret the results of these stress echocardiographic scans. New methods will be tested to measure the function of each part of the heart muscle, using advanced analysis of the information obtained when high-frequency sound waves are bounced off the heart inside the chest. The researchers will measure and report exact heart function during stress, so that they will be able to recognise normal hearts and those with any disease. New computer methods will be developed to display any abnormality, which will make it easier for doctors to choose the best treatment for patients who are at risk. The goals and potential benefits of this research proposal are to update the interpretation of a routinely used clinical test (stress echocardiography) to produce a reliable new method for diagnosing the precise effects of diseased arteries on the function of the heart muscle; to develop new computer graphics that adapt to show individual risks for each patient; and to implement new computer models that can be constantly updated

CABGpreHAB - a Feasibility Study Protocol

Patients with ischemic heart disease (IHD) awaiting coronary artery bypass graft (CABG) surgery often face challenges like advanced age, frailty, comorbidities, and physical inactivity. These factors, combined with the physiological and psychological stress of surgery, can hinder postoperative recovery. Traditionally, strategies to improve surgical outcomes focus on the intra- and postoperative periods. However, the pre-surgery waiting period offers a "window of opportunity" for prehabilitation, which aims to enhance patients' functional capacity through exercise, nutrition, and psychological support. The CABGpreHAB feasibility study evaluates the feasibility of a home-based multimodal prehabilitation intervention for patients awaiting elective CABG surgery. This randomized pilot study compares the intervention plus usual care to usual care alone, assessing feasibility outcomes like recruitment, retention, attrition, fidelity, and adherence. The study aims to optimize a subsequent full-scale randomized controlled trial (RCT) and improve patient outcomes by leveraging the pre-surgery period for prehabilitation.

First-in-Human Pilot Study of Epicardial Circular RNA-HM2002 Injection in CABG for Ischemic Heart Failure

This exploratory, single-center, open-label clinical trial assesses the safety, tolerability, and potential efficacy of a single 5 mg dose of HM2002 injection administered via multiple-point epicardial injections for treating ischemic heart failure. Three patients aged 18-80 undergoing elective coronary artery bypass grafting (CABG) surgery will participate. Using a sentinel dosing approach, the first subject will receive HM2002, followed by a 14-day safety observation before dosing the remaining participants. If any serious adverse events or dose-limiting toxicities occur in the first subject, a Safety Review Committee will evaluate the safety data to determine whether to continue or terminate the trial.

Outcomes of Drug Coated Balloon Angioplasty, A UK Real Life Experience From 2009 to 2015

This is a single center, retrospective, observational cohort study to assess the safety and efficacy of drug coated balloon (DCB) angioplasty in all forms of coronary artery disease. The Investigators intend to report outcomes of all patients who received DCB angioplasty at their center during the above mentioned period for up to 10 years.

iFR Guided Coronary Artery Bypass Grafting Surgery

The expected outcome of better and improved patency of bypass grafts and its direct relation to pre-operative iFR measurements of stenosis as compared to direct visual physiology of stenosis in the coronary angiogram. To establish the correlation between the use of intracoronary physiology and improved graft patency at 12 months for patients undergoing CABG surgery. It is a minimum of 28 and a maximum of 100 patients single-centre proof or concept/ observational study/ pilot study.

The OCTOBER Trial - European Trial on Optical Coherence Tomography Optimized Bifurcation Event Reduction (OCTOBER)

The purpose is to compare median two-year clinical outcome after OCT guided vs. standard guided revascularization of patients requiring complex bifurcation stent implantation

Echocardiography: Value and Accuracy at REst and STress

EVAREST will identify and validate novel blood and imaging biomarkers of potential value for consistent and accurate interpretation of stress echocardiography. During phase one, blood samples will be collected to assess the impact of cardiac stress on levels of circulating biomarkers and examine whether the measurement of these biomarkers can provide additional prognostic information. Phases one, two and three will also determine whether novel imaging biomarkers can be identified in the echocardiograms that can be used for objective interpretation of the stress echocardiograms. EVAREST will recruit up to 8000 patients (First 500 during phase one, an additional 500 during phase two and an additional 7000 during phase three) from multiple hospitals across United Kingdom, who have been referred for a stress echocardiogram as part of their investigations into ischaemic heart disease. Phase four of the study will continue into a clinical study cohort phase to capture information from all patients referred for a stress echocardiogram in the UK, regardless of the reason for investigation.This registry phase will run for 2 years, recruiting up to 15000 participants.
