Dalcetrapib Reduces Risk of New-Onset Diabetes in Patients With Coronary Heart Disease

OBJECTIVE

Incident type 2 diabetes is common among patients with recent acute coronary syndrome and is associated with an adverse prognosis. Some data suggest that cholesteryl ester transfer protein (CETP) inhibitors reduce incident type 2 diabetes. We compared the effect of treatment with the CETP inhibitor dalcetrapib or placebo on incident diabetes in patients with recent acute coronary syndrome.

RESEARCH DESIGN AND METHODS

In the dal-OUTCOMES trial, 15,871 patients were randomly assigned to treatment with dalcetrapib 600 mg daily or placebo, beginning 4–12 weeks after an acute coronary syndrome. Absence of diabetes at baseline was based on medical history, no use of antihyperglycemic medication, and hemoglobin A1c and serum glucose levels below diagnostic thresholds. Among these patients, incident diabetes after randomization was defined by any diabetes-related adverse event, new use of antihyperglycemic medication, hemoglobin A1c ≥6.5%, or a combination of at least two measurements of serum glucose ≥7.0 mmol/L (fasting) or ≥11.1 mmol/L (random).

RESULTS

At baseline, 10,645 patients (67% of the trial cohort) did not have diabetes. During a median follow-up of 30 months, incident diabetes was identified in 403 of 5,326 patients (7.6%) assigned to dalcetrapib and in 516 of 5,319 (9.7%) assigned to placebo, corresponding to absolute risk reduction of 2.1%, hazard ratio of 0.77 (95% CI 0.68–0.88; P < 0.001), and a need to treat 40 patients for 3 years to prevent 1 incident case of diabetes. Considering only those with prediabetes at baseline, the number needed to treat for 3 years to prevent 1 incident case of diabetes was 25. Dalcetrapib also decreased the number of patients who progressed from normoglycemia to prediabetes and increased the number who regressed from diabetes to no diabetes.

CONCLUSIONS

In patients with a recent acute coronary syndrome, incident diabetes is common and is reduced substantially by treatment with dalcetrapib.

Dogs born in summers more likely to suffer heart disease

Representational Image

Owing to a higher level of outdoor air pollution during summers, dogs born during this time are more likely to be at higher risk of heart disease, according to a study.

For both dogs and humans, outside air pollution during pregnancy and at the time of birth appears to play a role in later development of heart disease.

Overall, dogs have a 0.3 to 2 per cent risk of developing heart disease depending on breed, but among those that are genetically predisposed to the heart disease, the birth month difference in risk was found to be marginal.

However, breeds not genetically predisposed to the disease, such as Norfolk terrier, Berger Picard, American Staffordshire terrier, English toy spaniel, Bouvier des flandres, Border terrier and Havanese were also found to be at highest risk.

This suggests that the effect supports an environmental mechanism, the researchers said, in a paper published in the journal Scientific Reports.

The study, published in the journal Scientific Reports, also supports earlier findings in humans pointing to the role of early gestational exposure to fine air particulates and increased risk of heart disease later in life.

"It's important to study dogs because the canine heart is a remarkably similar model to the human cardiovascular system," said Mary Regina Boland, Assistant Professor at the University of Pennsylvania in the US.

"Also, humans and dogs share their lives together and are exposed to similar environmental effects, so seeing this birth season-cardiovascular disease relationship in both species illuminates mechanisms behind this birth-season disease relationship," Boland added.

Because dogs' pregnancies are shorter than humans (lasting only 2 months), pollution as a possible mechanism is still thought to be through the mother's inhalation of air pollution effecting the uterine environment, which in turn affects the developing cardiovascular system of the baby or puppy, the study showed.

For the new study, the team examined 129,778 canines encompassing 253 different breeds.

The research team found that risk climbs to the greatest level in dogs born in July, who have a 74 per cent greater risk of heart disease than would typically be expected.

Researchers flouting clinical reporting rules, and linking gut microbes to heart disease and diabetes

Though a law requiring clinical trial results reporting has been on the books for decades, many researchers have been slow to comply. Now, 2 years after the law was sharpened with higher penalties for noncompliance, investigative correspondent Charles Piller took a look at the results. He talks with host Sarah Crespi about the investigation and a surprising lack of compliance and enforcement. Also this week, Sarah talks with Brett Finlay, a microbiologist at the University Of British Columbia, Vancouver, about an Insight in this week’s issue that aims to connect the dots between noncommunicable diseases like heart disease, diabetes, and cancer and the microbes that live in our guts. Could these diseases actually spread through our microbiomes? This week’s episode was edited by Podigy. Listen to previous podcasts. About the Science Podcast Download a transcript (PDF).
