ACCORD: Primary Outcome

Page 25: Cardiovascular Disease and the Patient with Diabetes and Metabolic Syndrome Nathan D. Wong, PhD, FACC, FAHA Professor and Director Heart Disease Prevention.

Was Intensive Glycemic Control Harmful? A closer look at ACCORD AND ADVANCE

• ACCORD was discontinued early due to increased total and CVD mortality in the intensive arm. Major hypoglycemia 3-fold higher too.

• And the VA Diabetes Trial did show severe hypoglycemia to be a powerful predictor of CVD events.

• But a more recent analysis of ACCORD just published (Diabetes Care, May 2010) showed deaths to be associated with unsuccessful intensive therapy where A1c remained high.

• However, in both ACCORD AND ADVANCE, the subgroups without macrovascular disease at baseline had an actual benefit in the primary endpoint.

Page 26: Cardiovascular Disease and the Patient with Diabetes and Metabolic Syndrome Nathan D. Wong, PhD, FACC, FAHA Professor and Director Heart Disease Prevention.

2009 ADA/AHA/ACC Statement 2009 ADA/AHA/ACC Statement RecommendationsRecommendations

• Goal of A1c<7% remains reasonable – for uncomplicated patients

• ACC/AHA Class I (A)

– and for those with macrovascular disease • ADA Level B; ACC/AHA Class IIb (A)

• Incremental microvascular benefit may be obtained from even lower goals

• ADA Level B; ACC/AHA Class IIa (C)

• Less stringent goals may be appropriate for those with labile glucose control or with advanced micro- or macrovascular disease

• ADA Level C; ACC/AHA Class IIa (C)

HTN Control Rate Remains Poor in US Adults with MetS and DM from NHANES

2003-2004(Wong ND et al., Arch Intern Med 2007)

• Only 35% of those with DM on treatment for HTN are controlled to a goal of <130/80 mmHg

• Only 47% of those with MetS on treatment for HTN have a blood pressure of <130/85 mmHg

• Thus, JNC-7 recommendations to begin with combination therapy to improve goal attainment should be adhered to, esp. if SBP/DBP exceeds 20/10 mmHg from goal.

ACCORD: Effects of Intensive BP Control (NEJM 2010: 362: 1575-85)

• 4733 participants with type 2 DM randomly assigned to intensive therapy targeting a SBP <120 mmHg vs. standard therapy targeting a SBP<140 mmHg.

• Mean follow-up 4.7 years.• SBP after 1 year was 119 vs. 133 mmHg.• No difference in the primary endpoint of nonfatal MI,

stroke, or CVD death (annual rate): 1.9% vs. 2.1% (HR=0.88), p=0.20.

• Stroke annual rates significantly lower 0.32% vs. 0.53%, HR=0.59, p=0.01. Thus, overall benefit may be greater in populations with higher stroke risk.

Lipid Goals for Persons with Metabolic Syndrome and DM (Grundy et al., 2005)

LDL-C targets, ATP III guidelines

–High Risk: CHD, CHD risk equivalents (incl. DM or >20% 10-year risk): <100 mg/dL (option <70 mg/dl if CVD present)

– Moderately High Risk (10-20%) 2 RF: <130 mg/dL, option <100 mg/dL

– Moderate Risk (2+ RF, <10%) <130 mg/dL

-- Low Risk: 0-1 RF: <160 mg/dL

HDL-C: >40 mg/dL (men)

>50 mg/dL (women)

TG: <150 mg/dL

Page 40: Cardiovascular Disease and the Patient with Diabetes and Metabolic Syndrome Nathan D. Wong, PhD, FACC, FAHA Professor and Director Heart Disease Prevention.

Non-HDL: Secondary Target

• Non-HDL = TC – HDL

• Non-HDL: secondary target of therapy when serum triglycerides are 200 mg/dL (esp. 200-499 mg/dl)

• Non-HDL goal: LDL goal + 30 mg/dL

Specific Dyslipidemias: Specific Dyslipidemias: Elevated Triglycerides Elevated Triglycerides

Page 41: Cardiovascular Disease and the Patient with Diabetes and Metabolic Syndrome Nathan D. Wong, PhD, FACC, FAHA Professor and Director Heart Disease Prevention.

Management of Low HDL

• LDL is primary target of therapy

• Weight reduction and increased physical activity (if the metabolic syndrome is present)

• Non-HDL is secondary target of therapy (if triglycerides 200 mg/dL)

• Consider nicotinic acid or fibrates (for patients with CHD or CHD risk equivalents)

• 5518 patients with type 2 DM treated with open label simvastatin randomly assigned to fenofibrate or placebo and followed for 4.7 years.

• Annual rate of primary outcome of nonfatal MI, stroke or CVD death 2.2% in fenofibrate group vs. 1.6% in placebo group (HR=0.91, p=0.33).

• Pre-specified subgroup analyses showed possible benefit in men vs. women and those with high triglycerides and low HDL-C.

• Results support statin therapy alone to reduce CVD risk in high risk type 2 DM patients.

Smoking CessationSmoking Cessation

• What you do does matter. Physicians who intervene influence cigarette smoking behavior.

• How do you get your patients to quit smoking?– Identify i.e.: in vitals signs

– Interventions as brief as 3 minutes can significantly increase quit rates

– Dose dependent changes in behavior

– 5-10% may quit within 1 year with MD advice alone

• Smoking cessation aids

Conclusions

• Metabolic syndrome and diabetes are associated with increased levels of atherosclerosis and cardiovascular disease event risk

• Lifestyle measures focusing on weight reduction, dietary, and physical activity guidance are crucial in initial management.

Page 63: Cardiovascular Disease and the Patient with Diabetes and Metabolic Syndrome Nathan D. Wong, PhD, FACC, FAHA Professor and Director Heart Disease Prevention.

Conclusions (cont.)

• Clinical management emphasizes achievement of BP and lipid goals, glycemic control, and antiplatelet therapy.

• Multidisciplinary programs including primary care physicians, specialists (endocrinologists and cardiologists), dietitians, and exercise specialists are key for the successful management of these conditions.

Question #3Question #3

Diabetes has been considered a CHD risk equivalent because:

a) Nearly all persons with CHD also have diabetes

b) Persons with diabetes have a similar risk of developing CHD than those who already have CHD (e.g., myocardial infarction)

c) Both a and b

Page 68: Cardiovascular Disease and the Patient with Diabetes and Metabolic Syndrome Nathan D. Wong, PhD, FACC, FAHA Professor and Director Heart Disease Prevention.

Question #4Question #4

Recent large clinical trials such as ACCORD and ADVANCE suggest:

a) Aggressive glycemic control significantly reduces the risk of future CVD events in high risk persons with diabetes

b) The HbA1c target should be set closer to 6% than the conventional target of <7%

c) A less stringent goal than <7% for HbA1c might be considered in more complicated patients with diabetes (e.g., those difficult to control, with known macrovascular disease, or with long-standing diabetes)
