Impact of Age, Gender, and Body Mass Index on Short-Term Outcomes of Patients With Cardiogenic Shock on Mechanical Circulatory Support

This single-center, observational study assessed the impact of age, gender, and body mass index (BMI) in patients with cardiogenic shock (CS) on temporary mechanical circulatory support. All adult patients admitted to the Cleveland Clinic main campus Cardiac Intensive Care Unit (CICU) between December 1, 2015, to December 31, 2019, CICU with CS necessitating mechanical circulatory support (MCS) with intra-aortic balloon pump, Impella, or venous arterial-extra corporeal membrane oxygenation were retrospectively analyzed for this study. Baseline characteristics and 30-day outcomes were collected through physician-directed chart review. The impact of age, gender, and BMI on 30-day mortality was assessed using multivariable logistic regression. Kaplan-Meier survival curves were used to analyze the survival difference in specific subsets. A total of 393 patients with CS on temporary MCS were admitted to our CICU during the study period. The median age of our cohort was 63 years (interquartile range 54 to 70 years), median BMI was 28.50 kg/m2 (interquartile range 24.62 to 29.72) and 70% (n = 276) were men. In total, 22 patients >80 years had received MCS compared with 372 patients <80 years. Patients >80 years on MCS had significantly higher 30-day mortality compared with those <80 years (81.8% vs 49.3%, p = 0.006). Upon stratifying patients by BMI, 161 (41%) patients were found to have BMI ≥30 kg/m2 whereas 232 (59%) patients had BMI <30 kg/m2. Comparison of 30-day mortality revealed that patients with BMI ≥30 did significantly worse than patients with BMI <30 (59.6% vs 45.3%, p = 0.007). There was no difference in 30-day mortality between men and women. On multivariable logistic regression, both age and BMI had a positive linear relation with adjusted 30-day mortality whereas gender did not have a major effect. Advanced age and higher BMI are independently associated with worse outcomes in patients with CS on MCS. Utilizing a strict selection criterion for patients in CS is pertinent to derive the maximum benefit from advanced mechanical support.
