Self-monitoring of blood pressure with self-titration antihypertensives (self-management) results in lower patients hypertension, but there are no data about high-risk groups.To determine the effect self-monitoring antihypertensive medication compared usual care on systolic among cardiovascular disease, diabetes, or chronic kidney disease.A primary care, unblinded, randomized clinical trial involving 552 who were aged at least 35 years a history stroke, coronary heart disease and baseline...

Masked hypertension (MH) is defined as normal office blood pressure (OBP) and elevated ambulatory (ABP) or home (HBP). This study assessed MH identified by each of these two methods.A retrospective analysis cross-sectional data in treated untreated adults from Greece, Finland UK who had OBP, HBP 24-h ABP measurements was performed.

Home blood pressure (HBP) monitoring has become a primary method for hypertension diagnosis and management. This analysis aimed to investigate the optimal minimum schedule HBP monitoring.A retrospective of cross-sectional data was performed, which involved 24-h ambulatory (ABP) in adults performed within context clinical studies Finland, Greece UK. Participants with six seven days at least 12 readings were included. The stability assessed by evaluating average value an increasing number its...

Self-monitoring of hypertension is associated with lower systolic blood pressure (SBP). However, evidence for the use self-monitoring to titrate antihypertensive medication by physicians equivocal. Furthermore, there some efficacy telemonitoring in management but it not clear what this adds over and above self-monitoring. This trial aims evaluate whether GP led titration using results SBP compared usual care anything alone. will be a pragmatic primary based, unblinded, randomised controlled...

Abstract Background Self-monitoring of hypertension with self-titration antihypertensives (self-management) results in lower systolic blood pressure for at least one year. However, few people high risk groups have been evaluated to date and previous work suggests a smaller effect size these groups. This trial therefore aims assess the added value self-management over above usual care. Methods/Design The targets control stroke (TASMIN-SR) will be pragmatic primary care based, unblinded,...

Introduction People of South Asian, African-Caribbean and Irish ethnicity are known to have worse cardiovascular outcomes than those from the white British group. While reasons underpinning this complex, effect hypertension is both significant modifiable. In recent years, there has been increasing interest in uptake ‘out-of-office’ methods for blood pressure (BP) monitoring. However, guidance area largely based on research among population. This study aims answer following questions: (1) How...

Self-management of hypertension can reduce and control blood pressure (BP) compared with clinic monitoring. However, self-management relies on patients following an algorithm, which may be variably adhered to. This study reports fidelity high-risk to the algorithm set by TASMIN-SR trial.Patients hypertension, above target BP one or more stroke, diabetes, coronary heart disease chronic kidney disease, were invited self-monitor individualized self-titration algorithm.
