ABSTRACT
AIMS:
Although selected autoimmune diseases (AIDs) have been linked to an increased risk of ventricular arrhythmias (VAs), data on the long-term rate of VAs across the spectrum of AIDs are lacking. The aim of our study was to investigate the long-term rate of VAs (a composite of ventricular tachycardia, ventricular fibrillation, ventricular flutter, or cardiac arrest) in individuals with a history of 28 different AIDs.METHODS:
Individuals diagnosed with an AID (2005-2018) were identified through Danish nationwide registries. Each patient with AID was matched with four individuals from the background population by age and sex. Multivariable Cox regression was used to compare the rate of VAs between the AIDs and background population, overall and according to individual AIDs.RESULTS:
In total, 186,733 patients diagnosed with AIDs were matched with 746,932 individuals without AIDs (median age 55 years; 63% female; median follow-up 6.0 years). The 5-year cumulative incidence of VAs was 0.5% for patients with AIDs and 0.3% for matched individuals. Patients with any AIDs had a higher associated rate of VAs than matched individuals (HR 1.39 [95% CI, 1.29-1.49]). The highest HR was observed in patients with systemic sclerosis (3.86 [95% CI, 1.92-7.75]). The higher rate of VAs in patients with AIDs, compared with individuals from the background population, was more pronounced in patients without ischemic heart disease or heart failure/cardiomyopathy compared to those with these conditions (Pinteraction < 0.05).CONCLUSIONS:
Despite a low cumulative incidence, patients with a history of AIDs had a higher relative rate of VAs than matched individuals.
In a large Danish nationwide study, we examined the risk of ventricular arrhythmias, which are serious and potentially life-threatening conditions, in patients with and without a history of autoimmune diseases. Patients with a history of any autoimmune disease had a higher risk of experiencing ventricular arrhythmias compared with age- and sex-matched individuals from the background population. This association was observed for most of the autoimmune diseases when examined individually. The higher rate of ventricular arrhythmias in patients with autoimmune diseases, compared with individuals from the background population, was relatively more pronounced in patients without a history of ischemic heart disease or heart failure/cardiomyopathy compared with individuals with a history of these conditions.
