ABSTRACT
Introduction: As pharmacological treatment of hypertensionhas become a burden worldwide, the study looked into nonpharmacological ways of reducing blood pressure. Theobjective was to determine if music guided, slow and deepbreathing will reduce the blood pressure among patientswith hypertension in eight weeks.Methods: A participant blinded, multi-centre, randomisedcontrolled trial was conducted in which the participants inthe intervention group (IG) practiced deep breathingexercise guided by sound cues and those in the controlgroup (CG) listened to the music. The primary end point wasreduction in blood pressure at eight weeks.Results: 87 patients, 46 males and 41 females with mean ageof 61.1 years were recruited and 93.1% of them successfullycompleted the study. There was significant reduction insystolic and diastolic Blood Pressure from baseline by 8weeks in both groups. The reduction in Mean systolic bloodpressure (SBP) in the control arm was 10.5mmHg comparedto 8.3mmHg (p<0.001) in intervention group. Diastolic bloodpressure (DBP) reduction in control and intervention groupswere 5.2 mmHg (p<0.001) and 5.6 mmHg (p<0.001)respectively. The absolute difference in SBP reduction frombaseline in IG & CG was -2.2 (95%CI: -7.8 to 3.5) and DBPwas -0.4 (95%CI: -2.9 to 3.6). However, blood pressurereduction between the two groups was not significant.Conclusions: Both listening to music and deep breathingexercise were associated with a clinically significantreduction in SBP and DBP. However, deep breathingexercise did not augment the benefit of music in reducingBP.
