WebWhile glucose itself contains a carbonyl group that is involved in the initial glycation reaction, the most important and reactive carbonyls are formed by free radical-oxidation reactions damaging either carbohydrates (including glucose itself) or lipids. WebAfter multivariable adjustments for covariates, serum protein carbonyls remained statistically significant as a prognostic factor for eccentric LVH type, including greater LVEDD and LVEDV (β = 0.32 and β = 0.28, p < 0.001 for both) ( Table 2 ). TAC negatively correlated with both concentric and eccentric LVH phenotypes ( p < 0.05 in both cases).
