    Pregnancy-associated spontaneous coronary artery dissection (P-SCAD) presents more severely than nonpregnancy SCAD, with higher rates of major adverse cardiovascular events.

  • 2

    ST-segment elevation myocardial infarction (STEMI) occurred in 18.6% of P-SCAD patients, compared to 5.5% in nonpregnancy SCAD patients.

  • 3

    Patients with P-SCAD were more likely to have multivessel disease and a history of more than five pregnancies, indicating a more severe clinical profile.

  • 4

    Despite the severity, most patients in both groups were managed conservatively, with higher in-hospital adverse events noted in the P-SCAD group.

  • 5

    At one year, patients with P-SCAD had lower left ventricular ejection fraction recovery, with a significant proportion below 50%.
