SCAD (Spontaneous coronary artery dissection - tear in the arterial wall that is not related to trauma) is an under-diagnosed and poorly understood condition that mostly affects young women without common cardiovascular risk factors, and can result in heart attack and death. This observational study is designed to capture the disease's natural history and predisposing arteriopathies (medical conditions resulting in changes in the arteries), treatment strategies, long-term cardiovascular outcomes.
