Quality of Life in the Management of Hypertension Joel Handler MD Director, Kaiser Permanente Orange County Hypertension Program
Quality of Life Issues • What is health related quality of life (QOL)? • Is hypertension an asymptomatic disease? • What are the results of the QOL drug comparison trials? • How can we assess the adverse effects of the specific drug classes (thiazide, beta blocker, ACEI, ARB)? • How can we improve medication compliance?
What is health related quality of life?(HRQOL) Total well being = psychosocial and physical Total impact of an intervention on the biomedical, social and behavioral status of the patient HRQOL measures are a set of response variables beyond biomedical events: capabilities, limitations, perceptions
Quality of Life Components • Physical capabilities • Emotional status • Social interactions • Intellectual functioning • Economic status • Self-perceived health status
Health Related Quality of Life Measures in Chronic Disease • Alzheimer’s • Parkinson’s • Heart failure • HIV • MI recovery • Asthma • Cancer
Percentage of Subjects in NHANES Survey Reporting Symptoms Related to Systolic Blood Pressure Weiss NS NEJM 1972;287:631-633
Case Study 65 year old male with long standing anxiety disorder on paroxetine (Paxil) intolerant to HCTZ due to mouth dryness, also intolerant to atenolol with tremors, and both lisinopril and nifedipine with fatigue was referred to Hypertension Clinic because of refractory hypertension due to medication intolerance.
Case Study His psychiatrist attributed these symptoms to his underlying anxiety disorder. Paroxetine and bupropion (wellbutrin) were nonefficacious, but clonazepam (klonopin) led to a reduction in somatic complaints. HCTZ was successfully reinitiated, and in combination with lisinopril and atenolol led to control of his hypertension.

ACE Inhibitor Cough Incidence 5-40%; not dose related; higher rate in females, blacks, orientals Cough characteristics not helpful in diagnosis (may be productive) Timing: within a week to up to 6 months Resolution: 1-4 days, up to 4 weeks Pathophysiology: Bradykinin accumulation; no pulmonary dysfunction Things that don’t work: iron, NSAIDs, cromolyn Consider rechallenge

Conclusions • Quality of life is improved when blood pressure is under control • All drugs have adverse effect profiles • Quality of life drug comparisons are fairly equal with modern low dose strategies • Compliance strategies are challenging and need to be multileveled; the first 6 months of therapy is a critical period
