Background: Despite being the largest minority group, reports on the clinical outcomes in Hispanics undergoing either surgical [SAVR] or transcatheter aortic valve replacement [TAVR] is lacking.
Method: Using the 2011-2013 National Inpatient Sample [NIS] data, we compared the in-hospital adverse outcomes (mortality, strokes, MI, pacemaker implant) in Hispanic patients [HP] vs. non-HP post isolated SAVR and TAVR. In addition, we evaluated the impact of gender on clinical events following SAVR and TAVR in these 2 cohorts.
Results: Of the 71,223 patients [pts] who underwent SAVR, 6.1% were HP and 44.6% were women. HP were younger (74.7 years vs 75.6 years), more often diabetic (41.3% vs 29.2%) but less prior CABG (6.4% vs 8.7%) than Non-HP. For the 21,198 TAVR pts, 4.4% were HP, 51% were men. There were no difference in pt characteristics between HP & non-HP. Post SAVR, clinical outcomes in HP and Non-HP were similar. When stratified by gender, female HP had higher incidence of MI than non-HP. Post TAVR, HP had similar mortality as the non-HP [6.2% vs 4.7% respectively]. However, male HP had higher mortality compared to male non-HP. Multivariate regression analysis identified male HP as an independent predictor for in-hospital mortality (OR 2.38, 95% CI=1.12- 5.09, P=0.02) post TAVR but not SAVR (OR 1.13, 95%CI 0.65-1.97, P=0.66).
Conclusions: HP fared similarly as the non-HP regardless of gender post SAVR. However, post TAVR, male HP experienced >2-fold increase in mortality than non-HP which warrants further study.
