The document summarizes the key recommendations from the 2003 Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) guidelines. The guidelines simplified the blood pressure classification system to 4 categories and provided treatment algorithms. For prehypertension, lifestyle modifications were recommended, while for Stage I and II hypertension, lifestyle modifications combined with single or combination drug therapy were recommended. The guidelines emphasized lifestyle modifications like weight loss, following the DASH diet, reducing sodium intake, regular exercise, and moderate alcohol consumption. Common antihypertensive drug classes and their uses were also outlined.
