Key result

Patients with schizophrenia had a similar prevalence of abnormal ECGs compared to controls (54%), but antipsychotic use within this group was associated with abnormal ECGs (OR 1.20; 95% CI 1.04-1.39).

Why the study?

Data were limited on electrocardiogram characteristics and their association with psychotropic drugs in patients with schizophrenia.

Do patients with schizophrenia on psychotropic drugs have different ECG characteristics compared to matched controls?

Population

4486 patients with schizophrenia matched with 22 430 controls in Danish primary care

Comparison

Patients with schizophrenia vs matched controls without psychiatric disease

Design

Cross-sectional study

Overview

Antipsychotic use was associated with ECG abnormalities in schizophrenia; leaves open whether targeted monitoring improves outcomes.

Study Design

Type

Cross-Sectional (n=26,916)

Structured PICO

Do patients with schizophrenia on psychotropic drugs have different ECG characteristics compared to matched controls?

P
Population
26,916 Danish primary care patients, including 4,486 with schizophrenia and 22,430 matched controls without psychiatric disease, with a median age of 47 years and 45% female.
E
Exposure
Schizophrenia diagnosis and psychotropic drug use (specifically antipsychotics)
C
Comparator
Matched controls without psychiatric disease (matched 1:5 on age, sex, and ECG recording year)
O
Outcome
Prevalence of abnormal ECGs, heart rate, QTc interval, pathological Q waves, left ventricular hypertrophy, and atrial fibrillation or fluttersurrogate

Main Result

Absolute Event Rate: 54% vs 54%

p-value: p=.536

Patients with schizophrenia, particularly those on antipsychotics, exhibit a distinct cardiovascular risk profile on ECG, including elevated heart rate and QTc prolongation, highlighting the need for integrated care.

Cite This Study

Polcwiartek et al. (2019) conducted a cross-sectional in Schizophrenia (n=26,916). Schizophrenia vs. Controls without psychiatric disease was evaluated on abnormal ECGs (p=.536). Patients with schizophrenia had a similar prevalence of abnormal ECGs compared to controls (54%), but antipsychotic use within this group was associated with abnormal ECGs (OR 1.20; 95% CI 1.04-1.39).
