Methods An instrument was presented based on WHOQOL-BREF and SP-16 questionnaire and exercise testing. 57 normotensive and 76 hypertensive subjects aged 35-65 year-old participated the health survey using this instrument. Based on the exercise testing results of the two groups, a discriminate function was established and used to investigate cardiovascular risk factors for hypertensive population. Results The results showed that persons with hypertension rated significantly lower scores on physical health (i.e. limitation in performing daily activities and problems with work or mobility) than did normotensives (P < 0.01). The discriminant score obtained from the exercise testing results was capable of reflecting the impacts of hypertension on CVFS. Conclusions The method presented in this paper provides a more powerful tool to estimate the effects of health interventions and medical therapy for hypertensive population than just self-rated HRQOL questionnaire.展开更多

Design Multicenter, double-blind, placebo-controlled, parallel-group, randomized clinical trial of 216 sta- ble outpatients with HF, ejection fraction ≥ 50%, elevated N-terminal brain-type natriuretic peptide or elevat- ed invasively measured filling pressures, and reduced exercise capacity. Participants were randomized from October 2008 through February 2012 at 26 centers in North America. Follow-up was through August 30, 2012.展开更多
