5.2.12. Heart failure<br />
The association between heart failure and increase in DM 2 risk has been assessed<br />
(42) in 2,616 non-diabetic patients with coronary disease (myocardial infarction<br />
and stable angina).<br />
The subgroup with advanced heart failure (class III from NYHA) had a higher<br />
risk to develop diabetes [RR 1.7 (CI 95%: 1.1- 2.6)]; this was not the case for<br />
class II from NYHA. The study was initially not designed for this target group and<br />
neither did it consider the patients’ physical exercise.<br />

5.2.13. Drugs<br />
Atypical antipsychotic drugs<br />
Some studies (43) suggest that patients with schizophrenia present a higher DM<br />
prevalence than the general population, though its cause has not been fully established.<br />
A review of 17 studies (44) states that the treatment with olanzapine and<br />
clozapine is associated with a higher risk to develop DM, in comparison to those<br />
patients who are not being treated or who receive treatment with classic antipsychotic<br />
drugs. It also concludes that more comparative studies are required among<br />
the different antipsychotic drugs.<br />

Diuretics and beta-blockers<br />
The HTA Clinical Practice Guideline from the National Institute for Clinical<br />
Excellence (NICE) states that there is a higher risk to develop diabetes when a<br />
combination of beta-blockers and thiazidic diuretics (45) is used.<br />
An SR (<strong>46</strong>) assessed the effect of the different types of antihypertensives in<br />
the incidence of DM, including very heterogeneous studies. It concluded that the<br />
ARBII blockers and ACE inhibitors were the antihypertensives less associated<br />
with diabetes, followed by calcium channel blockers and placebo , beta-blockers<br />
and diuretics.<br />

Other drugs (47) involved in the development of diabetes are: glucocorticoids,<br />
oral contraceptives, tacrolimus, cyclosporine, nicotinic acid, protease inhibitor<br />
antiretroviral agents, gonadotropin agonist hormones, clonidine and pentamidine.<br />
