Data are given as median (interquartile range) unless otherwise indicated. A p-value of <0.05 is considered statistically significant.
DBP, diastolic blood pressure; SBP, systolic blood pressure; QTcBAz, QT interval corrected for heart rate; NYHA, New York Heart Association; 6MWT, 6-min walk test; KCCQ, Kansas City Cardiomyopathy Questionnaire. Bold values are statistically significant data.
