Predictive biomarkers of cardiovascular disease in adult Canadian population.

BACKGROUND: Elevated levels of the enzymes gamma-glutamyltransferase (GGT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and C-reactive protein (CRP) have been shown to be associated with increased risk of cardiovascular disease (CVD). Objective: To assess cross-sectional relationships between biomarkers GGT, ALT, AST, ALP and CVD in adult Canadian population.
METHODS: The Canadian Health Measures Surveys (CHMSs) are a series of cross-sectional national surveys and collect information on indicators of general health and wellness of Canadians. The CHMS has four components. We used data from the first three components (for Study participants ≥ 20 years) from CHMS cycles 1 through 5.
RESULTS: Multivariable logistic regression revealed: immigration status [Odds ratio (OR)(95% Confidence Interval (95% CI)) = 0.67 (0.53-0.85), reference category (RC)-no-immigrant] education [1.38(1.10-1.75), RC- > secondary education]; smoking status [ex-smokers: 1.16(0.89-1.51); current smokers: 1.41(0.98-2.05), RC-non-smoker]; and income [middle income: 0.69(0.43-1.10); high income: 0.49(0.29-0.83); RC-lower income] were significantly associated with CVD prevalence.
CONCLUSION: The relationship of GGT with CVD prevalence changed among age groups and body mass index categories; was different for males and females; and diabetes was an effect modifier in the relationship between AST and CVD prevalence. Socio-economic factors were significantly associated with CVD prevalence. © Springer Nature Switzerland AG 2021.
