Abstract:
:The introduction of second generation antipsychotics (SGA) represents a major advance in the treatment of schizophrenia. Concerns about the metabolic and cardiovascular adverse effects of the SGA have been widely disseminated. The benefits and risks of these drugs have been studied with a focus on particular organ systems. A basic principle of prevention is that the intensity of risk-reduction therapy should be adjusted to a individual's absolute risk. Hence, the first step is to assess an individual's risk status. The present study was designed to evaluate whether there is an added cardiovascular disease (CVD) risk in switching schizophrenia patients from typical antipsychotics to the SGA olanzapine. Risk status was determined by a 10-year risk assessment as recommended by the USA National Heart, Lung, and Blood Institute. This was carried out with Framingham scoring to identify individuals whose short-term (10-year) risk warrants consideration of intensive treatment. This risk was calculated for schizophrenia patients who were treated by haloperidol for a minimum period of 6 months and again following 6 months of exposure to olanzapine. Forty-three patients fulfilled inclusion criteria. There were 25 male and 18 female patients (mean age 40.7+/-2.4 years). The mean 10-year percentage risk of CVD for the group while on haloperidol treatment was 4.58+/-0.9 and, after 6 months of exposure to olanzapine, this was reduced to 4.12+/-0.9. Changes in the total risk and each evaluated risk variable were not statistically significant, except for a decrease in resting systolic blood pressure. Switching schizophrenia patients from typical antipsychotic treatment to olanzapine is safe and does not increase the long-term risk of cardiovascular disease.
