Does Lowering the Blood Pressure Improve the Mood? Quality-of-Life Results from the Hypertension Optimal Treatment (HOT) Study

Wiklund I, Halling K, Rydén-Bergsten T, Fletcher A on behalf of the HOT Study Group. Does lowering the blood pressure improve the mood? Quality-of-life results from the Hypertension Optimal Treatment (HOT) Study.

Nine-hundred-and-twenty-two hypertensive patients were included in a substudy to the Hypertension Optimal Treatment study, which aimed to investigate the impact on quality of life of lowering the pressure and of intensified therapy. Seven-hundred-and-eighty-one patients completed both baseline and follow-up questionnaires (intention-to-treat population), while 610 patients were included in a per protocol analysis. Patients were randomized to three diastolic BP levels (DBPs), i.e. ≤90mmHg, ≤85 mmHg and ≤80mmHg. Two self-administered validated questionnaires, the Psychological General Well-Being index and the Subjective Symptoms Assessment Profile (SSA-P) were completed at baseline and after 6 months. The lower the DBP achieved, the greater the improvement in well-being (p < 0.05). The increase in well-being from baseline to 6 months was significant in target groups 580 mmHg (p < 0.01) and 585 mmHg (p < 0.05). The SSA-P domains, cardiac symptoms and dizziness improved in all groups but the sex life score deteriorated in the 580 and 585 mmHg groups in male patients. In all target groups, headaches were reduced (p < 0.001), while swollen ankles (p < 0.001) and dry cough in the 180mmHg group (p < 0.001) increased. Although more intensive antihypertensive therapy is associated with a slight increase in subjective symptoms, it is nonetheless still associated with improvements in patients' well-being.
