NPPB and aortic stenosis: In the group of asymptomatic patients, those who experienced events (29 patients) during follow-up tended to be older (p = 0.086), had more severe AS (higher aortic peak jet velocity (p<0.001), smaller aortic valve area (p = 0.001)), larger left atrium (p = 0.011), higher BNP (p = 0.013) and sST2 (p = 0.001) levels (Table 3).
