About This Presentation

Description : Check out this medical PowerPoint presentation titled "Blood Pressure Control Evidence and Guidelines" by Prof. J. Hanacek.

This medical PowerPoint presentation talks about Blood Pressure Control Evidence and Guidelines. High blood pressure, also known as hypertension, is a common medical condition that affects a large number of people worldwide. It is a major risk factor for cardiovascular disease, stroke, and kidney failure, among other conditions. The management of hypertension involves controlling blood pressure to reduce the risk of these complications.

The presentation talks about evidence-based guidelines and recommendations for blood pressure control.

Classification of Recommendations and Levels of Evidence *Data available from clinical trials or registries about the usefulness/efficacy in different subpopulations, such as gender, age, history of diabetes, history of prior myocardial infarction, history of heart failure, and prior aspirin use. A recommendation with Level of Evidence B or C does not imply that the recommendation is weak. Many important clinical questions addressed in the guidelines do not lend themselves to clinical trials. Even though randomized trials are not available, there may be a very clear clinical consensus that a particular test or therapy is useful or effective. †In 2003, the ACC/AHA Task Force on Practice Guidelines developed a list of suggested phrases to use when writing recommendations. All guideline recommendations have been written in full sentences that express a complete thought, such that a recommendation, even if separated and presented apart from the rest of the document (including headings above sets of recommendations), would still convey the full intent of the recommendation. It is hoped that this will increase readers’ comprehension of the guidelines and will allow queries at the individual recommendation level.

BP should be measured at every routine DM visit. Patients found to have a SBP >130 mm Hg or a DBP >80 mm Hg should have BP confirmed on a separate day. A repeat SBP >130 mm Hg or a repeat DBP >80 mm Hg confirms a diagnosis of hypertension. Patients with DM should be treated to a SBP <130 mm Hg. Patients with DM should be treated to a DBP <80 mm Hg. Patients with a SBP 130-139 mm Hg or a DBP 80-89 mm Hg may be given lifestyle therapy alone for a maximum of 3 months, and then if targets are not achieved, patients should have pharmacologic agents added.

Patients with more severe hypertension (SBP >140 mm Hg or DBP >90 mm Hg) at diagnosis or follow-up should receive pharmacologic therapy in addition to lifestyle therapy.

Pharmacologic therapy for patients with DM and hypertension should be paired with a regimen that includes either an ACE inhibitor or an ARB. If one class is not tolerated, the other should be substituted. If needed to achieve BP targets, a thiazide diuretic should be added to those with an estimated GFR >30 ml/min and a loop diuretic with an estimated GFR <30 ml/min. Multiple drug therapy (two or more agents at maximal doses) is generally required to achieve BP targets. Source: American Diabetes Association.
