Primary outcome CV death, non-fatal myocardial infarction, or non-fatal stroke

The primary composite outcome in the time-to-event analysis was the first occurrence of death from cardiovascular causes, non-fatal myocardial infarction, or non-fatal stroke. The cumulative incidences were estimated with the use of the Kaplan–Meier method, and the hazard ratios with the use of the Cox proportional-hazard regression model. The data analyses are truncated at 54 months, because less than 10% of the patients had an observation time beyond 54 months. CI: confidence interval; CV: cardiovascular; HR: hazard ratio.

Recommendation 4

4.  In adults with type 2 diabetes with clinical cardiovascular disease in whom glycemic targets are not met, an antihyperglycemic agent with demonstrated cardiovascular outcome benefit should be added to reduce the risk of major cardiovascular events (Grade 1, Level 1A for empagliflozin ; Grade 1, Level 1A for liraglutide if age ≥50 years; Grade D, Consensus for liraglutide if age <50 years).

What should we do?

•  Do NOT use in type 1 diabetes

•  Remember EUGLYCEMIC diabetic ketoacidosis is a rare possibility

•  Be cautious with insulin dose reductions in “insulin deficient” pt

•  Be cautious in acute illness / surgery

•  Do not routinely check for ketonuria

S - sulfonylurea

A – ACE-inhibitor

D – diuretic, DRI

M - metformin

A - ARB

N - NSAIDs

S – SGLT2 inhibitors

Keeping it simple …

Insulin All options available

COULD THE PATIENT BE INSULIN DEFICIENT?

•  Lower BMI •  Lack of glycemic

lowering with other meds •  Duration of T2DM

(sometimes)

•  Higher BMI •  Shorter duration of

T2DM (sometimes)

Boiling it down …

1.  Does this patient have clinical cardiovascular disease? à empa or lira

2.  How high are the sugars? 3.  Is he/she at risk of hypoglycemia? 4.  What is the eGFR? 5.  Is there a drug plan?
