Spontaneous Coronary Artery Dissection (SCAD) is a heart condition where the inner lining of a coronary artery tears, causing blood to flow into the wall of the artery. This can lead to a heart attack (myocardial infarction) or sudden cardiac arrest. The iSCAD Registry is an international study aiming to collect information on SCAD to develop better treatments and guidelines. This study is both prospective (looking forward) and retrospective (looking back) and will help scientists understand SCAD better. SCAD often affects healthy people around 42 years old who don’t have typical heart disease risk factors. Symptoms can range from mild to severe, and the cause is still unknown.

• You must be 18 or older with a SCAD diagnosis or suspicion based on tests to join.
• The study is observational, meaning no treatment is given; it only collects data.
• If you can't understand or complete the study forms, you cannot participate.
