Diabetes and Cardiovascular Disease: Time To Act!

“With the rising tide of diabetes around the globe, the double jeopardy of diabetes and cardiovascular disease is set to result in an explosion of these and other complications- unless preventive action is taken.”

Prof Sir George Alberti, IDF President.

Page 24: Diabetic  dyslipidemia : The pro- atherogenic  role of CETP and future use of CETP inhibitors

Objective:To characterize IVUS defined coronary atherosclerosis progression in diabetic patients

Methods:Systematic analysis, 2,237 subjects in RCTs ofatherosclerosis progression, Reversal, Camelot, Activate, Asteroid and Illustrate . All patients had CAD, at least one lumen narrowing >20% on diagnostic arteriogram. The pattern of disease progression was compared in subjects with and without diabetes

Diabetic patients had a greater percent atheroma volume 40.2 ± 0.9% vs 37.5 ± 0.8% on multivariate analysis, p<0.0001 at baseline.

How to Increase HDL? Acute: Reconstituted HDL: eg A1 Milano (Arg 173 Cys) (IVUS) Delipidated HDL (IVUS) Apo A1 mimetics (?)Chronic: Diet and lifestyle: Weight reduction, diet, alcohol, exercise, smoking cessation Statins PPAR alpha agonists: fibrates (HHS; VAHIT; BIP; FIELD

ACCORD) PPAR gamma agonists: TZDs (PROactive, CHICAGO,

PERISCOPE) Dual PPAR Agonist aleglitazar Nicotinic acid (ER form; MK0524) (CDP, Numerous

regression trials) CETP inhibitors eg torcetrapib, (ILLUMINATE),

dalcetrapib, anacetrapib

Page 30: Diabetic  dyslipidemia : The pro- atherogenic  role of CETP and future use of CETP inhibitors

• 6661 patients with DM: in torcetrapib/atorvastatin arm vs. atorvastatin arm– significant lower plasma glucose levels: 0.34

ILLUMINATE: Recent Post Hoc Analysis:

Page 31: Diabetic  dyslipidemia : The pro- atherogenic  role of CETP and future use of CETP inhibitors

“If treatment with dalcetrapib and anacetrapib is found to be both antidiabetic and cardioprotective, there will be a compelling case for considering CETP inhibition as a treatment of choice in patients with type 2 diabetes mellitus”.

Background;Several clinical trials have reported inconsistent findings for the effects of fibrates on CVD risk

Methods:Systematic search 1950-2010. Included RCTs assessing the effects of fibrates on CVD outcomes. Summary estimates of relative risk (RR) reductionscalculated with random effects model.18 trials, 45058 participants, 2870 major CVD events, 4552 coronary eventsand 3880 deathsResults:Fibrate therapy associated with 10% RR reduction (95% CI 0-18; p=0.048) major CVD events 13% RR reduction (95% CI 7-19; p<0.0001 Coronary eventsNo impact on all-cause mortality, CVD mortality or sudden death

Objective: Will pioglitazone stabilize carotid artery vulnerable plaque in patients with acute coronary syndromes (ACS) and type 2 diabetes.

Population:61 patients with type 2 diabetes, age 63yrs, approx 70% male and echo lucent carotid plaques within 5 days of ACS. Random allocation to pioglitazone 15-30mg/day or matching placebo.

Methods:Vulnerable carotid plaques were assessed by measuring plaque echolucency using carotid ultrasound with integrated back scatter (IBS)An increase in IBS reflects an increase in plaque echogenicity.Echolucent plaques with low IBS represent identify lipid and macrophage-rich lesions, unstable plaques
