The benefits of regular exercising for patients with hypertension need more informative clinical studies, claims a new report.

People with increased blood pressure receive much well meant advice, for example, to adopt stress-management strategies, smoke less and drink less alcohol.

The researchers at German Institute for Quality and Efficiency and Health Care (IQWiG) were particularly interested firstly, to know whether people with hypertension, by exercising more, can actually reduce the risk of heart attacks or stroke, and secondly, to determine how more exercise affects their health-related quality of life.

Patients in the intervention group had been advised to exercise more over a longer period of time (e.g. cycling, running, hiking, swimming), while those in the control group had not been given this advice. In addition, only studies lasting 24 weeks or more were considered.

Overall, IQWiG and its external experts included 8 randomised controlled trials lasting 6 to 12 months in the assessment.

As the assessment showed, the studies considered in the report allow no conclusions on patient-relevant aspects of the benefit of increased physical activity in hypertension.

The studies did not provide sufficient results, neither on mortality, disease of the heart and circulatory system (cardiovascular morbidity), and kidney failure (end-stage renal disease), nor on health-related quality of life.
