- BACKGROUND: Patients with type 2 diabetes are at high risk of fatal and non-fatal myocardial infarction and stroke. There is indirect evidence that agonists of peroxisome proliferator-activated receptor gamma (PPAR gamma) could reduce macrovascular complications. Our aim, therefore, was to ascertain whether pioglitazone reduces macrovascular morbidity and mortality in high-risk patients with type 2 diabetes. METHODS: We did a prospective, randomised controlled trial in 5238 patients with type 2 diabetes who had evidence of macrovascular disease. We recruited patients from primary-care practices and hospitals. We assigned patients to oral pioglitazone titrated from 15 mg to 45 mg (n=2605) or matching placebo (n=2633), to be taken in addition to their glucose-lowering drugs and other medications. Our primary endpoint was the composite of all-cause mortality, non fatal myocardial infarction (including silent myocardial infarction), stroke, acute coronary syndrome, endovascular or surgical intervention in the coronary or leg arteries, and amputation above the ankle. Analysis was by intention to treat. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN NCT00174993. FINDINGS: Two patients were lost to follow-up, but were included in analyses. The average time of observation was 34.5 months. 514 of 2605 patients in the pioglitazone group and 572 of 2633 patients in the placebo group had at least one event in the primary composite endpoint (HR 0.90, 95% CI 0.80-1.02, p=0.095). The main secondary endpoint was the composite of all-cause mortality, non-fatal myocardial infarction, and stroke. 301 patients in the pioglitazone group and 358 in the placebo group reached this endpoint (0.84, 0.72-0.98, p=0.027). Overall safety and tolerability was good with no change in the safety profile of pioglitazone identified. 6% (149 of 2065) and 4% (108 of 2633) of those in the pioglitazone and placebo groups, respectively, were admitted to hospital with heart failure; mortality rates from heart failure did not differ between groups. INTERPRETATION: Pioglitazone reduces the composite of all-cause mortality, non-fatal myocardial infarction, and stroke in patients with type 2 diabetes who have a high risk of macrovascular events.

- The combination of clopidogrel plus ASA did not improve limb or systemic outcomes in the overall population of PAD patients requiring below-knee bypass grafting. Subgroup analysis suggests that clopidogrel plus ASA confers benefit in patients receiving prosthetic grafts without significantly increasing major bleeding risk.

- We compared cardiovascular disease outcomes according to the presence of peripheral arterial disease (PAD) at baseline in a post hoc analysis from the PROactive study. Of the 5238 patients in PROactive (a study of pioglitazone versus placebo in patients with type 2 diabetes and macrovascular disease; mean follow-up=34.5 months), 1274 had PAD at baseline (619=pioglitazone; 655=placebo). Patients with PAD at baseline showed significantly higher rates of the primary endpoint, main secondary endpoint, all-cause mortality (all P<0.0001), and stroke (P=0.0175) than those with no PAD at baseline. The risk of PAD alone was similar to that of myocardial infarction alone. In patients with no PAD at baseline, the event rates of the primary endpoint (P=0.0160), main secondary endpoint (P=0.0453), and acute coronary syndrome (P=0.0287) were significantly lower with pioglitazone than with placebo. This beneficial effect of pioglitazone was not seen in patients with PAD at baseline. In the total population, there was a higher frequency of leg revascularizations with pioglitazone than placebo-this was wholly due to first events that occurred within the initial 12 months of treatment. The presence of PAD increased the risk of all major cardiovascular events. Those without PAD at baseline seemed to benefit more from pioglitazone treatment than the overall PROactive population.
