Abstract
Objective
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that increases the risk of cardiovascular disease, but the causal relationship has remained unknown in the East Asian population. We aim to determine the causal relationship between SLE and congestive heart failure (CHF) in the East Asian population.
Methods
We conducted a two-sample Mendelian randomization MR study to examine the potential causal association of SLE with CHF, using the East Asian genome-wide association study datasets for SLE (4222 cases, 8431 controls) and CHF (9413 cases, 203,040 controls).
Results
The MR analysis showed that genetic susceptibility to SLE was associated with the increased risk of CHF (odds ratio [OR] 1.032, 95% confidence interval [CI] 1.004–1.061, p = .023). After excluding the human leukocyte antigen (HLA) regions, SLE was also associated with a higher risk of CHF (OR 1.034, 95% CI 1.007–1.062, p = .015). The multiple MR sensitivity analyses confirmed that this potential causal association was unlikely to be biased by horizontal pleiotropy.
Conclusions
The findings of this MR study suggest that SLE potentially increases the risk of CHF in the East Asian population. Genetic predisposition to SLE may play a significant role in developing CHF in the East Asian population.
