Abstract

Antipsychotics are associated with cardiovascular risk, but the relationship between their anticholinergic properties and cardiac function is not clear. We hypothesize that antipsychotics with a high muscarinic affinity (HMA) may reduce parasympathetic modulation, which should be observable by means of heart rate variability (HRV) measurement. We also assume that anticholinergics, which are commonly used in patients with schizophrenia to treat drug-induced parkinsonism, interact with antipsychotics, and this may also affect HRV. Fifty-five patients with schizophrenia were recruited into this study. Twenty-eight subjects used antipsychotics with an HMA and 27 subjects used antipsychotics with a low muscarinic affinity (LMA). Heart rate variability values between the patients on antipsychotics with HMA and those on antipsychotics with LMA were compared. Correlation and regression analysis were then performed to clarify the relationship between HMA, LMA, and HRV. The influence of anticholinergics was also assessed by correlation analysis. The HMA group showed significantly reduced low-frequency (LF) power, high-frequency (HF) power, total power (TP), and normalized LF (LF%) than the LMA group. Regression analysis supported the hypothesis that muscarinic affinity was related to LF (β = -0.447; P < 0.001), HF (β = -0.390; P = 0.002), and TP (β = -0.399; P = 0.001). The interaction between LMA and anticholinergic use also influenced LF% (β = 0.326; P = 0.006). In the LMA group, the use of anticholinergics was positively correlated with LF% and LF/HF. In the HMA group, after exclusion of the patients using anticholinergics, the equivalent dose of antipsychotics showed a negative correlation with HF. Our results suggest that the muscarinic affinity of antipsychotics affects both sympathetic and parasympathetic modulation and that anticholinergics interact with antipsychotics to influence HRV.

  • There is a negative correlation between neurocardiac control and the degree of antipsychotic affinity and antagonism of muscarinic receptors, with high muscarinic affinity antipsychotics clozapine, olanzapine and quetiapine showing greater reductions in heart rate variability than low muscarinic affinity antipsychotics risperidone and aripiprazole.

    “There appears to be a negative correlation between neurocardiac control and the degree of AP affinity and antagonism of muscarinic receptors (M1-M5), with high muscarinic affinity APs (clozapine, olanzapine and quetiapine) showing greater reductions in HRV than low muscarinic affinity APs (risperidone and aripiprazole)48–50.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
