Trends of Incidence, ClinicalPresentation, and In-Hospital Mortality Among Women With Acute MyocardialInfarction With or Without SpontaneousCoronary Artery Dissection

OBJECTIVES The authors sought to determine the clinical characteristics and in-hospital survival of women presenting

with acute myocardial infarction (AMI) and spontaneous coronary artery dissection (SCAD).

BACKGROUND The clinical presentation and in-hospital survival of women with AMI and SCAD remains unclear.

METHODS The National Inpatient Sample (2009 to 2014) was queried for all women with a primary diagnosis of AMI and concomitant SCAD. Iatrogenic coronary dissection was excluded. The main outcome was in-hospital mortality. Propensity score matching and multivariable logistic regression analyses were performed.

RESULTS Among 752,352 eligible women with AMI, 7,347 had a SCAD diagnosis. Women with SCAD were younger (61.7 vs. 67.1 years of age) with less comorbidity. SCAD was associated with higher incidence of in-hospital mortality (6.8% vs. 3.4%). In SCAD patients, a decrease in in-hospital mortality was evident with time (11.4% in 2009 vs. 5.0% in 2014) and concurred with less percutaneous coronary intervention (PCI) (82.5% vs. 69.1%). Propensity score yielded 7,332 SCAD and 14,352 patients without SCAD. The odds ratio (OR) of in-hospital mortality remained higher with SCAD after propensity matching (OR: 1.87, 95% confidence interval [CI]: 1.65 to 2.11) and on multivariable regression analyses (OR: 2.41, 95% CI: 2.07 to 2.80). PCI was associated with higher mortality in SCAD patients presenting with non–ST-segment elevation myocardial infarction (OR: 2.01, 95% CI: 1.00 to 4.47), but not with STEMI (OR: 0.62, 95% CI: 0.41 to 0.96).

CONCLUSIONS Women presenting with AMI and SCAD appear to be at higher risk of in-hospital mortality. Lower rates of PCI were associated with improved survival, with evidence of worse outcomes when PCI was performed for SCAD in the setting of non with ST-segment elevation myocardial infarction.
