The document discusses guidelines for the treatment of hypertension. It provides a history of changes to major hypertension guidelines over time, including changes in target blood pressure levels and recommendations for first-line treatment options. It also reviews compelling indications for specific antihypertensive drug classes based on concomitant diseases or conditions. The guidelines emphasize lifestyle modifications and use of diuretics, ACE inhibitors, angiotensin receptor blockers, or calcium channel blockers as preferred initial treatment options for most patients with hypertension.
2. WHY DO WE NEED GUIDELINES ?
Physicians are continuously flooded with studies.
Guidelines should help to find the right way through this jungle of information.
Experts should review existing data to provide clear recommendations based on evidence.
Guidelines are increasingly used by healthcare providers and politicians to assess the “appropriate use” and develop disease management programs.

33. Summary of evidence in patients with diabetes and hypertension
•SBP lowering below 140 mmHg appears beneficial with respect to all cause mortality and stroke
•SBP lowering below 135mmHg or 130 mmHg appears to confer significant benefit with respect to stroke
•As SBP decreases below 140 mmHg, the risk of SAEs increasesbut the absolute number of these events is low

54. MDs have not been aggressive enough in controlling hypertension in their patients
Patients w/ DM & CKD require more aggressive BP control
Most patients with hypertension will require two or more antihypertensive medications to control blood pressure
The use of combination therapy is appropriate as initial treatment
Sustained antihypertensive efficacy may protect against the early morning rise in blood pressure that leads to heightened risk of cardiovascular events
