ABSTRACT
BACKGROUND AND AIMS:
Observational studies have demonstrated that serum branched-chain amino acids (BCAAs) are associated with the risk of various cardiovascular diseases (CVDs) and their risk factors. However, the causal effect is unclear. The aim of this study was to investigate the effect of genetically determined BCAA levels on CVDs and their risk factors using Mendelian randomization (MR). METHODS ANDRESULTS:
We performed univariable and multivariable MR analyses using summary-level data from multiple GWASs and the FinnGen consortium to investigate the association between BCAA levels and the risk of CVDs (myocardial infarction, ischemic stroke, and intracerebral hemorrhage) and their risk factors (atrial fibrillation, hypertension, heart failure, and valvular heart disease). We used the random-effects IVW approach as the primary statistical method and incorporated MR estimates from different data sources using the fixed-effects model. We found genetically determined total and individual BCAA levels and a high risk of hypertension. However, there is no evidence of a causal relationship between BCAA levels and 3 cardiovascular diseases and other their risk factors. The odds of hypertension increased per 1-SD increase in BCAA levels (OR = 1.02 95% CI 1.01, 1.04; P = 0.005), valine (OR = 1.02 95% CI 1.01, 1.03; P<0.0001), leucine (OR = 1.02 95% CI 1.01, 1.04; Pï¼0.01), and isoleucine (OR = 1.02 95% CI 1.01, 1.03; P < 0.0001). This result was also significant in the multivariable MR.CONCLUSIONS:
This MR study suggests that total and individual BCAA levels could be associated with a high risk of hypertension.Palavras-chave
