Abstract
We investigated the incidence and characteristics of 14,996 patients with aortic stenosis (AS) who were hospitalized in New Jersey between the years 1995 to 2015. The average age was 72, the majority were Caucasian males and common co-morbidities were hypertension, coronary artery disease and hypercholesterolemia. Hospital admission for AS declined between 1995 to 2007, to 10/100,000 patients, and increased to 15/100,000 patients in 2015 (p for trend <0.001). During the study period, the percentage of patients who received aortic valve replacement (AVR) increased (p <0.001). All-cause and cardiovascular mortality were higher among patients who did not undergo AVR at 1-year (HR 1.98 CI 1.75 to 2.23, p <0.001 and HR 1.82 CI 1.57 to 2.11, p <0.001, respectively) and 3-years (HR 2.16 CI 1.96 to 2.38, p <0.001 and HR 2.16 CI 1.90 to 2.45, p <0.001, respectively). The probability for readmission for AS was higher in patients who did not receive AVR compared to patients who had AVR at 1 year (HR 92.95 CI 57.85 to 149.35, p <0.001) and 3 years (HR 70.36 CI 47.18 to 104.95, p <0.001). These data imply that earlier diagnosis of AS and AVR when indicated will improve outcomes.
