1) Evaluate the mechanisms linking diabetes, heart failure, and cardiovascular disease.

2) Examine the evolution of T2D drug development and factors leading to the requirement to evaluate cardiovascular safety for glucose lowering therapies.

3) Appraise new and emerging CVOT data for glucose lowering therapies and compare available CVOT data within the T2D therapeutic classes.

4) Compare and contrast CVOT data with updated guideline recommendations and discuss management and prevention strategies in patients with HF and/or CVD.

5) Using a case-based approach, explore unanswered questions and clinical challenges in applying CVOT data to real-world patient care.

6) Recognize opportunities for cardiologists to collaborate with endocrinologists, primary care providers, and other members of the healthcare team to improve outcomes for patients with T2D, HF, and CVD.

• Pre-prandial PG <130 mg/dL

• Post-prandial PG <180 mg/dL

1. People with diabetes are at increased risk for ASCVD and HF.

2. However, correcting diabetes’ major metabolic defect—hyperglycemia—has had little effect on reducing these complications.

3. Glucose-lowering medications could pose potential benefits and/or potential risks to the CV system.

4. Until recently the impact of older drugs themselves (i.e., beyond glucose-lowering) on actual CV outcomes in T2D patients has been either neutral or inconsistently demonstrated.

5. In 2008, the FDA provided guidance to industry to conduct large CV outcome trials in order ensure that new diabetes therapies would at least safe for the heart.

6. Over the past 3 years, we have seen important new results from these trials….

“The strategies of audit and feedback andeducational outreach visits were generally effective in improving both process of care and clinical outcomes...multifaceted interventions appeared to be more effective. ”

Chan W, et al. Circulation. 2017.

A health-system engagement strategy that will:

• Provide audit/feedbackthrough monthly, live interactions to mentor health teams in design, measurement, and monitoring of local quality improvement action plans

• Provide educational outreach with specialized quality improvement (QI) training

The Cost of Not Taking Your MedicineBy Jane E. Brody

“There is an out-of-control epidemic in theUnited States that costs more and affects morepeople than any disease Americans currentlyworry about. It’s called nonadherence toprescribed medications, and it is—potentially,at least—100 percent preventable by the veryindividuals it afflicts.

“The numbers are staggering. ‘Studies haveconsistently shown that 20 percent to 30 percent

of medication prescriptions are never filled, and that approximately 50 percent of medicationsfor chronic disease are not taken as prescribed,’ according to a review in Annals of InternalMedicine. People who do take prescription medications—whether it’s for a simple infectionor a life-threatening condition—typically take only about half the prescribed doses.”

Brody JE. The New York Times. April 17, 2017.

Each 10% improvement in ACC/AHA heart failure guideline-recommended composite care was associated with a 13% lower odds of 24-month mortality (adjusted OR 0.87; 95% CI, 0.84–0.90; P<0.0001).

• Diabetes is a growing problem with heart failure as an even worse outcome

• Prevention is the key for success

• We need to use systems of care to implement evidence faster than 17 years…our patients deserve it!

• Patients, clinicians, and systems matter

• Opportunities to improve outcomes are in everyone’s hands

• Learn what’s best on how to deliver every day!
