Abstract 14177: Alarming Burden and Disparities of MACCE in Postmenopausal Women of a Contemporary Nationwide Cohort, 2020

Abstract

Background: Cardiovascular disease is the leading cause of death worldwide, with a notable impact on postmenopausal women. However, contemporary large-scale population-based data for the burden and disparities of Major Adverse Cardiovascular and Cerebrovascular Events (MACCE) in this population remains limited. Methods: The National Inpatient Sample (2020, ICD10 codes, age>55 years) was queried to identify postmenopausal women's hospitalizations. Socio-demographics, racial subgroups, comorbidities, and MACCE rates were retrieved with a more granular comparative analysis in postmenopausal women. A p<0.05 was considered statistically significant. Results: Of the total 8435195 postmenopausal women hospitalizations (median age 75 years), 1021375 (12.1%) were identified with MACCE. MACCE cohort, in comparison to non-MACCE cohort, had significantly higher prevalence of hypertension (77.1% vs 71.3), diabetes (39.8% vs 34.0%), hyperlipidemia (53.7% vs 48.4%), PVD (9.8% vs 7.1%), prior MI (8.3 vs 5.7%), prior TIA/stroke (10.5 vs 9%) and CKD (29.4 vs 23.4%). Significant clinical predictors for all-cause mortality were found to be race Asian/PI vs white ( 1.31 [1.09-1.18]), median household income national quartile (1.16 [1.13-1.20]), hypertension (1.18[1.16-1.20]) diabetes (1.20 [1.19-1.22]), hyperlipidemia (1.12[1.11-1.14]), prior MI (1.37[1.34-1.40]) and prior TIA stroke (1.0 5 [1.03-1.07] (all p<0.05). Conclusion: Among hospitalizations, Asian/Pacific Islanders, patients from the lowermost income quartile with co-existent hypertension, diabetes, hyperlipidemia, CKD, and cardiovascular comorbidities independently revealed the highest MACCE rates. Special emphasis needs to be laid on socio-demographics, comorbidities, and racial differences for CVD disease prevention, and risk factor modification in postmenopausal women.
