Atypical Antipsychotics Influence on the Safety of the Heart and Monitoring Indicators Model Building

Atypical antipsychotics, also known as new antipsychotics, are a group of drugs that act on the central nervous system to treat schizophrenia, psychotic disorder or bipolar disorder. Compared with typical antipsychotics, atypical antipsychotics have the advantages of good efficacy and fewer side effects. Therefore, currently, atypical antipsychotics are widely used in clinical practice. In recent years, the effects of atypical antipsychotics on metabolism and cardiovascular system have attracted more and more clinical attention. Studies have found that long-term use of atypical antipsychotics can lead to arrhythmias, drug-induced myocarditis, and even cardiac arrest. Since antipsychotics can cause cardiac adverse events in patients with schizophrenia, accompanied by medical complications, resulting in a generally shorter life span of 15-25 years compared with the general population, cardiac safety assessment of drugs for patients with schizophrenia is becoming increasingly important. But the domestic study of antipsychotics in the cardiovascular field, especially about the safety of heart systemic evaluation are few and far between, so this research has focused on patients with schizophrenia in China people use different mechanisms of atypical antipsychotics (Risperidone, Aripiprazole, Ziprasidone, Amisulpride, Quetiapine) on heart safety.

In the first stage, a total of 350 schizophrenia patients were enrolled who were either not on medication for the first time or stopped for more than 2 weeks. They were treated with atypical antipsychotics respectively, follow-up of 12 weeks, evaluating the effects of antipsychotics on cardiac function and structure in patients with schizophrenia from general data, biochemistry, electrocardiogram, etc. In the second stage, 50 patients of adverse cardiac reactions caused by taking antipsychotics were selected from enrolled subjects, and a retrospective analysis(day1, week4, week12, and week24) was conducted to try to build a cardiac safety detection indicator model, so as to understand the impact of antipsychotics on cardiac safety. More rational use of antipsychotics in the context of ensuring clinical efficacy and minimum side effects, and the use of monitoring indicator models to reduce the occurrence of cardiac toxicity, improve the safety of antipsychotics in use.
