Abstract

Background and aims: To investigate the significance of 9 amino acids as risk factors for incident cardiovascular disease events in 9584 Finnish men.

Materials and methods: A total of 9584 men (age 57.4 ± 7.0 years, body mass index 27.2 ± 4.2 kg/m2) from the Metabolic Syndrome in Men study without cardiovascular disease and type 1 diabetes at baseline were included in this study. A total of 662 coronary artery disease (CAD) events, 394 ischemic stroke events, and 966 cardiovascular disease (CVD; CAD and stroke combined) events were recorded in a 12.3-year follow-up. Amino acids were measured using nuclear magnetic resonance platform.

Results: In Cox regression analysis, phenylalanine and tyrosine were significantly associated with increased risk of CAD and CVD events, and phenylalanine with increased risk of ischemic stroke after the adjustment for confounding factors. Glutamine was significantly associated with decreased risk of stroke and CVD events and nominally with CAD events. Alanine was nominally associated with CAD events.

Conclusion: We identified alanine as a new amino acid associated with increased risk of CAD and glutamine as a new amino acid associated with decreased risk of ischemic stroke. We also confirmed that phenylalanine and tyrosine were associated with CAD, ischemic stroke, and CVD events.

Keywords: amino acids; cardiovascular disease; coronary artery disease; ischemic stroke.

Hazards ratios (HR) and their 95% CIs for the associations of 9 amino acids with the risk of coronary artery disease (CAD), ischemic stroke, and cardiovascular disease (CVD) events (N = 9584). HR values were adjusted for age, diabetes status, fasting insulin, smoking, body mass index, low-density lipoprotein cholesterol, drug treatment for hypertension, high-sensitivity C-reactive protein, high-density lipoprotein cholesterol, and statin treatment.
