Background: Clinical outcomes of women vs. men following left side heart valve [aortic or mitral] surgery are not well characterized.
Method: Using the 2003-13 National Inpatient Sample data, we compared the gender specific in-hospital outcomes by performing 1:1 propensity score matching and conditional logistic regression.
Results: Of the 284,707 patients who underwent left side heart valve surgery, 47.9% were female. Women were older, had higher prevalence of hypertension, pulmonary hypertension, CHF, and anemia while men had higher prevalence of smoking, hyperlipidemia, renal disease, CAD, prior PCI and CABG [All P <0.0001]. Following propensity score matching, we analyzed the in-hospital clinical outcomes in 43,004 [50% female]. Female patients had higher mortality, bleeding required transfusion, iatrogenic vascular complications, and respiratory failure compared to male counterparts [see table]. The all-cause in-hospital mortality following left heart surgery has improved significantly for both genders (men: 5.2% in 2003 to 2.7% in 2013; women: 7.2% to 3.9% respectively) during the study period [Ptrend: <0.0001].
Conclusions: In this retrospective analysis, women fared worse than men with a significantly higher in—hospital all-cause mortality following left heart surgery. The mortality has improved significantly for both genders over the study period.
