2. Rev. Stephen Hales (1677-1761) BP = 8 feet 3 inches of water 3. April 12, 1945 4. PROFILE OF THE DISEASE 5. How Common is this Duo? HTN is twice as common in DMHTN is twice as common in DM New onset DM is 2.5 times in HTN 20 to 40% of IGT pts have HTN20 to 40% of IGT pts have HTN 40 to 50% of Type 2 DM have HTN40 to 50% of Type 2 DM have HTN Only 1/4 of HTN in DM is controlledOnly 1/4 of HTN in DM is controlled DM + HTN CV Risk 3 foldDM + HTN CV Risk 3 fold 6.

UKPDS: Tight blood control and risk of macrovascular and microvascular complications in T2DM 1148 patients randomized to right control or less tight control Tight control defined as < 150/85 mm Hg Less tight control defined as < 180/105 mm Hg Half of tight control to ACE inhibitors (captopril) and half to beta blockers (atenolol) Mean follow-up of 8.4 years Part of larger UKPDS with follow-up every 3-4 months 10.

HOT: Hypertension Optimal Treatment 18,790 patients from 26 countries, age 50 -80, and diastolic blood pressure 100-115 mm Hg were recruited Patients were randomized to 3 groups based on diastolic pressure goal (< 90, < 85, and < 80 mm Hg) Primary endpoint was composite macrovascular outcome of non-fatal MI, non-fatal stroke, or CV death Major finding was that patients with diabetes had a 51% reduction in primary endpoint No increase in side effects.

ADVANCE 215 centers in 20 countries with 11,140 patients with type 2 diabetes randomized to fixed combination of perindopril and indapamide or matching placebo, Primary endpoints were composites of major macro- and microvascular events Death from CV disease, non-fatal stroke or non-fatal MI New or worsening renal or diabetic eye disease 19. ADVANCE: a factorial randomised trial of blood pressure lowering and intensive glucose control in 11,140 patients with type 2 diabetes Effects of a fixed combination of the ACE inhibitor, perindopril, and the diuretic, indapamide on major vascular events Lancet 2007 Sept 8;370:829-40 Presented at European society of Cardiology, Vienna, 9/2/07 20. ADVANCE RESULTS 4.3 years of follow-up Compared to placebo, there was a drop in pressure of 5.6/2.2 mm Hg There was not a significant decrease in macrovasular (p = 0.16) events or microvascular events (p = 0.16) separately There was a 9% decrease in combination(p=0.04) There was a decrease in CV death (p = 0.03) and death from any cause (p = 0.03) Lancet 370:829, 2007 21.
