High blood pressure has become increasingly prevalent and is an important risk factor for cardiovascular disease. The Seventh Report of the Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) has redefined normal blood pressure as less than 120/80 mm Hg and created a new blood pressure category called "prehypertension" for those with a systolic BP of 120 to 139 mm Hg or a diastolic BP of 80 to 89 mm Hg. This new blood pressure category was created to identify adults considered to be at risk for developing hypertension and to alert both patients and healthcare providers of the importance of adopting lifestyle changes. Recognition of prehypertension provides important opportunities to prevent hypertension and cardiovascular disease.

Randomized Controlled Trial Multicenter Study Clinical Trial
Public defibrillation: increased survival from a structured response system.
The Public Access Defibrillation (PAD) trial was a prospective, randomized, controlled study designed to compare the number of persons surviving to hospital discharge after experiencing an out-of-hospital cardiac arrest (OOH-CA) among "community units" randomized to receive cardiopulmonary resuscitation (CPR) only or CPR plus an automated external defibrillator (AED). In 24 centers across the United States and Canada, 993 community units, composed of 1260 individual facilities, trained more than 19,000 layperson responders in CPR-only or CPR+AED. ⋯ Use of an AED within this structured response system can increase the number of survivors to hospital discharge after OOH-CA. Trained nonmedical responders can use AEDs safely and effectively.
