Some heart disease patients could benefit from blood pressure medication, researchers have claimed.
Patients with aortic stenosis - which affects around 5% of people in the developed world - can suffer breathlessness and chest pain during exercise.
The condition sees the narrowing of the main valve between the heart and the rest of the body, causing a partial blockage.
Patients often undergo surgery to have the valve removed and replaced - but many do not notice any symptoms.
The team from the University of Dundee and NHS Tayside said that sufferers not experiencing the symptoms could potentially see their need for an operation delayed through the use of blood pressure drugs.
The study, funded by the charity Tenovus, looked at 20 years of data on patients with aortic stenosis who have had heart scans in that period
The researchers found “significantly lower” death rates and heart troubles among patients taking drugs such as ACE inhibitors and angiotensin blockers. The research is published in the Journal of the American College of Cardiology.
