The "Virtual" Multicenter Spontaneous Coronary Artery Dissection (SCAD) Registry

The primary goal of this project is to describe the clinical and physiologic characteristics of Spontaneous Coronary Artery Dissections (SCAD) in order to increase awareness, understanding, treatment and prevention of a potentially fatal cardiovascular event. This study will be a retrospective and prospective review of medical course and current health of men and women with SCAD.

Norwegian Spontaneous Coronary Artery Dissection Study

The Norwegian Spontaneous Coronary Artery Dissection Study (NOR-SCAD) is a national, multicenter prospective observational study conducted at major hospitals in Norway. The study investigates risk factors and complications of spontaneous coronary artery dissection (SCAD). Patients aged 18 years or older who are hospitalized with SCAD are recruited during the index hospitalization. Each participant will be followed for 52 weeks with scheduled visits at 8 and 12 weeks and a final phone call at 52 weeks. Evaluations include coronary CT angiography (CTA), cardiac assessments, genetic analyses, blood sampling, structured questionnaires, and a cardiopulmonary exercise test (CPET).

Genetic Investigations in Spontaneous Coronary Artery Dissection (SCAD)

The purpose of the research is to identify mutations (defects in the genetic blueprint) that cause spontaneous coronary artery dissection (SCAD), in other words, spontaneous tears in blood vessels that supply the heart. Some mutations may be inherited (passed on) from a parent without an apparent blood vessel problem while others may develop for the first time in the affected person.

Impact of CYP2C19 Genotype-guided Approach in Antiplatelet Therapy on Platelet Reactivity Index Among Coronary Artery Disease (CAD) Patients

The goal of this clinical trial is to learn if the pilot intervention of CYP2C19 genotype-guided antiplatelet therapy works to reduce the occurrence of cardiovascular events after Percutaneous Coronary Intervention (PCI) done in coronary artery disease patients. It will also learn about the comparison between clopidogrel and ticagrelor. The main questions it aims to answer are: To compare the impact of CYP2C19 genotype-guided antiplatelet therapy, universal use of clopidogrel and ticagrelor treatment on platelet reactivity. To compare the impact of CYP2C19 genotype-guided antiplatelet therapy, universal use of clopidogrel and ticagrelor treatment on the risk of major adverse cardiovascular events (MACE) among newly recruited stable CAD patients. Participants will: Take drug clopidogrel or ticagrelor, based on the random group allocation every day for 1 month. One group of patients will undergone CYP2C19 genetic test for genotype-guided antiplatelet therapy, whether clopidogrel or ticagrelor. Visit the clinic post 30 days of PCI for follow-ups and platelet function tests.

Clinical Cohort Study - INTERCATH

Within a CAD patient cohort there is a wide variability of clinical manifestation and severity of coronary disease. Distinct determinants that would explain the variety of CAD phenotypes with differing prognosis are yet undiscovered. Aim of this study is to find genetic variants, biomarkers, and clinical cardiovascular risk factors that relate to specific coronary artery disease phenotypes and related pathologies in a patient population.
