Clinical course of pregnancy-associated spontaneous coronary artery dissection: a case series
Abstract
Abstract Background Spontaneous coronary artery dissection (SCAD) is the most important cause of acute coronary syndromes during pregnancy and in the post-partum period and involves a spontaneous intimal tear or intramural haematoma of a coronary artery. Pregnancy-associated SCAD accounts for a minority of SCAD cases but is associated with a high rate of adverse events. Case summary We present a series of three cases with pregnancy-associated SCAD. All patients presented with acute coronary syndromes in the post-partum period, between 12 days and 5 months after delivery. They all had additional conditions that are associated with SCAD, such as fibromuscular dysplasia and migraine. The management of one patient was uncomplicated, however, the courses of the other two were characterized by adverse events. One presented after an out-of-hospital cardiac arrest, the other presented with multivessel SCAD and developed progression and recurrence of SCAD during follow-up. In conclusion, the patients could be successfully treated conservatively and were in good condition at their latest follow-ups. Discussion This case series highlights the wide range of clinical courses that could exist in pregnancy-associated SCAD, from a benign manifestation to a life-threatening condition. Importantly, those patients are at an increased risk for acute and late adverse events.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
