Abstract

Aim. To study the morphological and functional heart disorders in patients with different duration of antipsychotic treatment. Material and methods. Medical documents of 78 deceased schizophrenic patients treated with antipsychotic drugs were studied. The patients were split into 4 groups depending on duration of neuroleptic treatment: group 1 — <10 years, group 2 — 11-20 years; group 3 — 21-30 years, group 4 — >30 years. ECG-disorders and left ventricular morphometric data were analyzed. Сorrelation analysis of myocardium morphological changes and electrophysiological disorders was performed. Results. The dependence of morphometric myocardium changes on the treatment duration was found: increase in stromal-parenchymal ratio (from 9.9±4.1% to 80.0±10.1% in groups 1 and 4, respectively), in specific volume of atrophied cardiomyocytes (from 8.0±3.8% to 45.1±12.6% in groups 1 and 4, respectively), in specific volume of degenerative cardiomyocytes (from 5.2±3.1% to 35.2±12.1% in groups 1 and 4, respectively). Increased incidence of extrasystole detection (from 2.2% to 11.2% in groups 1 and 2, respectively), as well as left anterior fascicular block (from 1.1% to 25.9% in groups 1 and 2, respectively) and left ventricle hypertrophy (from 2.2% to 18.5% in groups 1 and 4, respectively) were found. A strong positive correlation (r=0.88–0.99) was revealed between antipsychotic treatment duration and ECG disorders, as well as between morphological myocardium state and ECG disorders. Conclusion. Awareness about the neuroleptic-depended ECG changes is necessary for early diagnosis, secondary prevention and correction of existing heart disorders due to cardiotoxic side effects of antipsychotic drugs.
