Why Care

Risk reduction of CVD in diabetics

?

Can we prevent CVD risk in diabetics

Risk reduction of CVD in diabetics Primary prevention of diabetes

Why Doesn’t Glucose

Reduction Lower the Risk of

Macrovascular Disease?

Would more intensive glucose control (targeting

6-6.5%) or longer follow-up result in decreased CV complications?

Would longer follow-up

result in decreased CV complications?

THANK YOU FOR TRYING TO STAY AWAKE

has confused me as to the

relationship of glucose control

and heart disease

The ACCORD study

• Drug-drug interaction

• Imperfect glucose- lowering drugs

• Weight gain

• Hypoglycemia

Potential causes of increased mortality during intensified therapy

ACCORD: putting the results into perspective

One size fits all

Was Mao correct?

One size fits all

One size fits all

With different sizes

One size doesn’t fit all

There has been recent change from “standerdized” to “personalized” approaches

One size doesn’t fit all

Big change from one size fits all

Subgroup analysis

Paradise and small details

The good physician treats the disease; the great physician treats the patient who has the disease. William Osler

12 July 1849 – 29 December 1919

1. Different subgroups may need different goals

2. Randomized controlled trial subgroup analysis

3. It may be rational to treat specific patients at specific times

Subgroup approach

Blood Pressure, Lipids and Glucose in Type 2 Diabetes

How Low Should We Go

European Heart Journal. Sep 2011

Re-Discovering Personalized Care

Recent clinical trials have suggested that

some patient subgroups might respond differently to aggressive risk

factor management. Our challenge is how to identify these patients and deliver truly personalized diabetes care that maximizes benefit and minimizes harm

VADT: CVD martality predictors

- Patients had longest duration since diabetes diagnosis at baseline (>10 years)

- Had highest baseline HbA1c concentrations

- Greater risk of hypoglycemia

Can we make sense of recent

What did we learn from the recent megatrials?

● timing: short disease duration

● baseline HbA1c value: 7.5- 8.0%

● age of patient: young/middle aged

● speed and degree of glycemic control: gradual lowering

of HbA1c, and a target HbA1c between 6.5– 7.0%

● co-morbidity: absence of overt CVD of multiple CVD risk factors.

● patient-specific conditions: education, finance and family support.
