Coronary Microvascular Function and CT Coronary Angiography (CorCTCA)

AnginaStable3 more

Angina in patients without obstructive coronary artery disease (CAD) is a clinical conundrum and patient management is heterogeneous. Hypothesis: Abnormal coronary function is common and clinically relevant in this population. Design: An observational cohort study and nested randomised controlled diagnostic strategy trial. Methods: 250 patients with known or suspected angina informed by validated questionnaires but without obstructive CAD (<70% stenosis) in an artery >=2.5 mm or structural heart disease, as revealed by CT coronary angiography (CTCA), will be invited to undergo coronary function testing (FFR, CFR, IMR; intra-coronary ACh) during invasive angiography. Patients will be randomised following angiography but before testing coronary function to disclosure of the coronary function test results or not. Treatment decisions by the attending cardiologist will be recorded before and after disclosure of results. Outcomes: Primary: The between-group difference in the reclassification rate of the initial diagnosis using logistic regression, adjusted for baseline factors associated with the likelihood of reclassification of the initial diagnosis. Secondary: Prevalence of microvascular or vasospastic angina; health status reflected by the EuroQol group 5-Dimensions (EQ-5D), Seattle Angina Questionnaire, Illness perception, treatment satisfaction questionnaires and functional status questionnaires; angina medication and adherence. Value: This research will provide new insights into the conundrum of angina in patients without obstructive CAD or structural heart disease.

IMR Evaluation in Patients With Coronary Sinus Reducer Implantation (INROAD Study)

Refractory Angina Pectoris

The INROAD is an investigator-driven, prospective, study in which patients undergoing coronary sinus reducer implantation (Reducer) for chronic refractory angina undergo evaluation of the index of microcirculatory resistance (IMR) at the time of implantation, and at 4 months follow-up

COMPLEX Registry - A Prospective COhort Study to Describe the Management and Outcomes of Patients...

Coronary DiseaseCoronary Artery Disease10 more

The purpose of the COMPLEX Registry is to prospectively and retrospectively collect baseline, clinical and procedural data of patients who have undergone PCI or CABG for complex and/ or calcified chronic CAD, irrespective of clinical presentation as well as to prospectively collect data about their clinical outcomes. The outcomes will be compared in different clinical subgroups (e.g. PCI vs. CABG). The impact of current PCI techniques/ devices, but also CABG strategies in different clinical settings and coronary artery lesions on cardiovascular outcomes will be assessed.

Refractory Angina

The objectives of the study are to assess the safety, tolerability, and potential efficacy of IMB-1018972 on patients with refractory angina. Study will assess functional capacity employing a modified Bruce Protocol treadmill ETT, patient reports of angina symptoms via an electronic diary, and activity using an accelerometer.

Echocardiography: Value and Accuracy at REst and STress

Coronary Artery DiseaseIschaemic Heart Disease1 more

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.

Impact of Spiroergometer Parameters as Diagnostic Marker of Cardiac Ischemia in Pts. With Stable...

Stable Angina

In Patients with stable Angina pectoris CCS 1-3 exercise testing for ischemia detection is widely used despite the known limitations. Measurement of the FFR is invasive but gold standard for Ischemia detection. Adding of parameters of spiroergometer might help to improve diagnostic accuracy of non invasive exercise testing. Therefore the trial is evaluating diagnostic accuracy of spiroergometric parameters compared to invasive FFR measurement.

Extracorporeal Shockwave Therapy for the Treatment of Chronic Angina Pectoris

Refractory Angina Pectoris

Low intensity shockwaves have been proven in animal studies to induce local growth of new blood vessels from existing ones. The hypothesis of this study is that shockwave therapy could improve the symptoms of patients with refractory angina not amenable to revascularization with angioplasty or bypass surgery.

MICRO: a Registry Study in Patients With Microvascular Angina

Microvascular Disease

The evidence above demonstrates that microvascular dysfunction is an important determinant of patient prognosis, which however remains poorly classified. Given the high burden of disease and the severity of the functional impairment in these patients, the lack of a clear definition for this disease has a potentially large clinical importance. It is important to better describe the phenotype of these patients, identify the predictors of prognosis, and determine the impact of diagnosis.
