Cardiovascular Risk Reduction and Other Co-Morbidities in Type 2 Diabetes

Following this presentation, you will be able to:

• Describe the relationship between major CV risk factors and CVD outcomes

• Select therapeutic modalities available to practitioners to improve CV risk factors

• Discuss other co-morbid/microvascular conditions seen in patients with type 2 diabetes

• Recognize the implications of recent large trials on guiding clinical decisions and targets for blood pressure and lipid abnormalities

• Explain the role of pharmacologic intervention in the treatment of type 2 diabetes

CV = cardiovascular; CVD = cardiovascular disease.

Type 2 Diabetes and CVD

Lewis GF. Can J Cardiol. 11(suppl C):24C-28C, 1995; Norhammar A, et.al. Lancet 359;2140-2144, 2002; NCEP ATP III. Circulation. 2002;106(25):3143; Meigs, et al. Am J Med. 1997;102:38-47.

CAD = coronary artery disease; CHD = coronary heart disease; CVD = cardiovascular disease; MI = myocardial infarction.

• Type 2 diabetes is considered a CHD equivalent

• Atherosclerotic complications are responsible for:

– 80% of mortality among patients with diabetes

– More than 75% of all hospitalizations for diabetic complications

• 50% of patients with type 2 diabetes have preexisting CAD

• One-third of patients presenting with MI have undiagnosed diabetes mellitus

Age-standardized Rates ofDiabetes Complications: 1990-2010

Gregg EW, et al. N Engl J Med 370:1514-1523, 2014.

ESRD = end-stage renal disease.

Rates of diabetes-related complications declined between 1990 and 2010

(relative risk reductions):Myocardial infarction -68.8%, death from hyperglycemic crisis -64.4%,

end-stage renal disease -28.3%, stroke and amputation ~50%

How Is CAD Different in Diabetes?

• > CAD extent• Multi-vessel disease

• Distal disease – more difficult to revascularize

• Silent ischemia/MI

• Younger

• Women

• Worse outcomes despite revascularization• Increased re-stenosis after PCI even with stents

• ACB: worse perioperative and long-term outcomes

ACB = aortocoronary bypass; CAD = coronary artery disease; MI = myocardial infarction; PCI = percutaneous coronary intervention.

• HDL cholesterol raising

Behavior: weight loss, physical activity, smoking cessation

Glycemic control

Intensity of Statin Therapy (Doses in mg/day)

Stone NJ et al. Circulation. 2014;129[suppl 2]:S1-S45

Boldface type indicates specific statins and doses that were evaluated in RCTs included in CQ1, CQ2, and the Cholesterol Treatment Trialists 2010 meta-analysis

included in CQ3. All of these RCTs demonstrated a reduction in major cardiovascular events. Italic type indicates statins and doses that have been approved by the FDA

but were not tested in the RCTs reviewed.

Individual responses to statin therapy varied in the RCTs and should be expected to vary in clinical practice. There might be a biological basis for a less-than-average

response.

†Evidence from 1 RCT only: down-titration if unable to tolerate atorvastatin 80 mg in the IDEAL (Incremental Decrease through Aggressive Lipid Lowering) study.

‡Although simvastatin 80 mg was evaluated in RCTs, initiation of simvastatin 80 mg or titration to 80 mg is not recommended by the FDA because of the increased risk

of myopathy, including rhabdomyolysis.

BID indicates twice daily; CQ, critical question; FDA, Food and Drug Administration; LDL-C, low-density lipoprotein cholesterol; and RCTs,

randomized controlled trials.
