27 Case Vignette 2: Jake (continued) History: Type 2 diabetes x 5 years PAD with percutaneous transluminal angioplasty (PTA) and stent of superficial femoral artery 3 years ago Hypertension 45 pack year smoking history: quit after the PTA Minimal exercise, but trying to walk more Physical Exam: BP 128/78 mm Hg BMI 28 kg/m 2 Rest of exam unremarkable Labs: A1C 7.8% (was 7.5% 8 months ago) LDL-C 1.79 mmol/l ACR 4.8 mg/mmol egfr 64 ml/min/1.73 m 2 Current Medications: Metformin 1 g bid Linagliptin 5 mg daily Perindopril 8 mg daily Rosuvastatin 20 mg daily ASA 81 mg daily PAD: peripheral arterial disease;; ACEi: angiotensin-converting-enzyme inhibitor;; BMI: body mass index;; BP: blood pressure;; A1C: glycated hemoglobin;; egfr: estimated glomerular filtration rate;; LDL-C: low-density lipoprotein cholesterol;; ACR: albumin to creatinine ratio;; ASA: acetylsalicylic acid 27

29 Patients with Diabetes are More Likely to be Hospitalized for Many Conditions Prevalence rate ratios of complications among hospitalized individuals aged >20 years, by diabetes status, Canada, 2008/09 22 Rate ratios (with diabetes: without diabetes) COMPLICATION Cerebrovascular disease (stroke) Acute myocardial infarction (heart attack) Ischemic heart disease Heart failure Chronic kidney disease End-stage renal disease Lower limb amputations Rate ratios based on rates age-standardized to the 1991 Canadian population. A person with diabetes hospitalized with more than one complication was counted once in each category, except for cases of acute myocardial infarction, where regardless of multiple counts in the acute myocardial infarction category, the individual was counted only once under the broader ischemic heart disease category.

30 Clinical Approach to Jake Jake has CVD and diabetes and is at high risk of other CV events (e.g., stroke, MI) Review the ABCDs for vascular protection: A: A1C his A1C is above target B: BP his BP is well controlled C: Cholesterol his cholesterol is at target D: Drugs to protect the heart he is on an ACEi, statin and ASA Priorities will be getting Jake to target A1C to reduce risk of microvascular events, particularly given that he has evidence of early kidney disease, and using an antihyperglycemic agent with demonstrated CV benefits CVD: cardiovascular disease;; ACEi: angiotensin-converting-enzyme inhibitor;; BP: blood pressure;; A1C: glycated hemoglobin;; ASA: acetylsalicylic acid 30
