EXAMINE-CAD-DZHK22 is a prospective, randomized, double-blind, placebo-controlled, crossover trial investigating the efficacy of beta blocker (bisoprolol) and calcium channel blocker (diltiazem) therapy in symptomatic patients with non-obstructed coronary arteries according to coronary physiological testing results.

Implantable Cardioverter Defibrillator Versus Optimal Medical Therapy In Patients With Variant Angina...

Angina PectorisVariant1 more

The purpose of this study is to determine whether ICD(Implantable Cardioverter Defibrillator) implantation on the top of optimal medical therapy in patients with variant angina manifesting as aborted sudden cardiac death reduces the incidence of the death from any cause compared with optimal medical therapy alone.

iCorMicA - Stratified Medicine in Angina

Microvascular AnginaAngina9 more

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.

ReACHallenge Trial: Acetylcholine Rechallenge After Pretreatment With Vasoactive Drugs

Angina PectorisVariant2 more

The goal of this clinical trial is to assess the feasibility and clinical value of acetylcholine (ACH) rechallenge after intracoronary verapamil +- nitroglycerine in a patient cohort with angina and non-obstructive coronary arteries (ANOCA). The main questions it aims to answer are: to determine the efficacy of these drugs in treating ACH-induced coronary artery spasm to determine the efficacy of these drugs in preventing ACH-induced coronary artery spasm The ACH rechallenge will take place during the index coronary function tests in patients with proven ACH-induced vasospastic angina. The study is considered a feasibility study, no control arm is included.

Angina PectorisVariant

The purpose of this study is to determine whether BVS(Bioresorbable Vascular Scaffold) implantation with optimal medical therapy can improve the outcome of patients with variant angina and moderate coronary artery disease.

Coronary Microcirculatory Disease and Inflammation in Patients With Chronic Coronary Syndrome and...

Coronary Artery DiseaseIschemia and No Obstructive Coronary Arteries3 more

Patients with chronic coronary syndromes (CCS) diagnosed without significant lesions in invasive coronary angiography (ischemia non-obstructive coronary artery disease - INOCA) represent approximately 50% of all patients with CCS. Results of FAME study clearly showed that evaluation of coronary circulation should not be accomplished only with visual assessment in resting conditions. Current European Society of Cardiology Guidelines of diagnosis and treatment of CCS published in 2019 emphasize the necessity of performing complex coronary physiology assessment. Invasive physiological measurements and vasoreactivity provocative tests emerged as key tools to differentiate between vasospastic angina, microcirculatory angina, overlap of both conditions or non-cardiac disease. According to contemporary literature, identification of heterogeneity of patients with INOCA is crucial for determination of adequate treatment. An appropriate pharmacotherapy has a potential to improve outcomes including grade of angina, quality of life, exertional tolerance and most important - MACCE (major adverse cardiac and cardiovascular events) free survival. However, there is a lack of evidence on each of the subtypes of INOCA especially in those with signs and symptoms of vasospasm in provocative test but without visual spasm in epicardial vessels.

Myocardial Ischemia Without Obstructive Coronary Stenoses

Myocardial IschemiaNon-Obstructive Coronary Atherosclerosis3 more

Coronary-related myocardial ischemia can result from obstructive epicardial stenosis or non-obstructive causes including coronary microcirculatory dysfunction and vasomotor disorders. This prospective study has been created in order to provide knowledge in the field of non-obstructive coronary artery disease.

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.

A Multi-Omics Study of Vasospastic Angina

Vasospastic Angina

This is a observational study to identify the key factor associated with vasospastic angina and to explore the prognosis of the participants. The study will recruit 400 patients with vasospastic angina, 400 healthy controls and 400 patients with acute myocardial infarction. Next generation sequencing, metabolome and proteomics will be performed in these participants.

Evaluate the Efficacy and Safety of Pletaal (Cilostazol) in Subjects With Vasospastic Angina

Variant Angina

The objective of this study is to investigate the efficacy and safety of Pletaal (Cilostazol) in comparison with placebo for 4 weeks in vasospastic angina patients who have an insufficient response to Amlodipine (Calcium channel blocker).
