Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
If this is successful and cost-effective such technology and interventions could be utilized on large scale to improve the care and proportion of hypertensive patients achieving goal blood pressure in the United States.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This barrier to effective hypertension treatment achieves further significance as data from several clinical trials clearly demonstrate that reduction of blood pressure by even a few millimeters of mercury can significantly decrease an individual risk for mortality from cardiovascular disease8.
Although hypertension remains the most common reason for patient visit to a physician office in the United States, the lack of patient-health care provider connectivity outside the office setting may play an important factor in the disappointing proportion of patients achieving blood pressure control in the US for the past 30 years.
Recent home blood pressure monitoring guidelines published by the American Heart Association and other professional societies have emphasized the importance of home blood pressure monitoring in the management of hypertension9. In addition, a recent study by Green et al extended this concept a step further by utilizing a web based intervention utilized by a pharmacist to control blood pressure10. Results from this study they demonstrated a significant reduction in blood pressure in the intervention group when compared to usual care (-14.2 mmHg Vs -5.3 mmHg p \<0.001).
One of the potential draw backs of a web based intervention for blood pressure control could be the lack of access to internet in the general population. According to a recent USDA report, almost 40% Americans in urban areas and 60% in rural areas do not have internet access (http://arstechnica.com/tech-policy/news/2009/03/the-many-blessing-of-rural.ars ). This in essence would deprive a large number of those with hypertension from access to the web based newer models of blood pressure control as tested in the recent study by Green et al.
The Stabil-o-Graph is a validated home blood pressure device (http://www.dableducational.org/dabl\_library/library2\_sbpm.html#upper\_arm) that relays blood pressure readings to a designated health care provider using blue tooth technology and a telephone connection
The current model of health care in the US for the management of hypertension employs direct patient-physician encounters in an office setting to control blood pressure. This existing healthcare model has failed to keep abreast with current national guidelines and consensus among experts in hypertension that promote home blood pressure monitoring and application of newer technology with the potential to seamlessly connect a patient with his health care provider with the goal of improved blood pressure control.
Our proposed study aims to address this gap in patient-healthcare provider connectivity utilizing newer technology and home blood pressure monitoring to achieve goal blood pressure foe an individual.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Virtual Hypertension Clinic Group
In the VHC group, patients will be ask to regularly measure blood pressure with the Stabil-o-Graph so that these readings are transmitted to Virtual Hypertension Clinic. The data will be reviewed weekly and the patient will receive feedback and intervention if needed at every 2 week interval to achieve blood pressure goal. Once they reach goal, the feedback will be less intense and given at four week intervals till the end of the study.

The data will be reviewed weekly and the patient will receive feedback and intervention if needed at every 2 week interval to achieve blood pressure goal. Once they reach goal, the feedback will be less intense and given at four week intervals until the end of the study.
Usual Care Group
The Usual Care Group (UCG) patients will be told their BP is not in control and encouraged to work with their physician to improve it. There will be no further structured intervention during the rest of the study.
No interventions assigned to this group
