Evaluating the effectiveness and acceptability of Bluetooth remote home blood pressure (BP) monitoring in patients following a transient ischaemic attack (TIA) or stroke.
High blood pressure (hypertension) is one of the most prevalent diseases worldwide and is a major modifiable risk factor for recurrent stroke and vascular disease. However rates of control in practice are low, and are often partly due to reliance on single BP readings taken in clinic.
Home BP monitoring is becoming increasingly important in the diagnosis and management of hypertension and has been recommended in international guidelines. It is useful as it negates the effect of “white coat hypertension”, allows for multiple BP readings to be collected, giving better prognostic accuracy than clinic measurements alone and helps detect BP variability allowing more appropriately-informed titration of treatment. In addition patients are also able to see the direct effect of antihypertensive medication on their BP which in turn may aid long term compliance.
The project involves giving Bluetooth enabled home blood pressure monitoring kits to patients following a TIA or stroke. The benefit of this system, supplied by a local company OBS Medical Ltd, is the BP readings are transmitted automatically at the time the measurement is taken, so clinicians can see up-to-date readings and adjust treatment if necessary.
The main aims of the project are to evaluate whether home Blue-tooth monitoring of blood pressure will help us identifying patients after a TIA or stroke with variable blood pressure, enable us to refine our understanding of the causes and consequences of BP variability and hopefully lead to more effective treatment of hypertension with existing medication in the future.
