Abstract
Objective Vitamin A antioxidant role has an important relationship with the metabolic processes of aging and cardiovascular disease (CVD). This study aimed at assessing the liver store of retinol in elderly individuals who died from cardiovascular disease and its relationship with liver weight and body weight. Methods and Results This is a cross-sectional study conducted in necropsied individuals, aged 60 years or over, until 48 hours postmortem. The study assessed 65 elderly individuals who died from ischemic heart diseases (G1), cerebrovascular diseases (G2), other forms of heart disease (G3), or infectious heart diseases (G4). Twenty percent had inadequate liver store of retinol. G1 showed lower median of liver store of retinol when compared to G3 (p < 0.001), and G3 showed the highest median when compared to G2 (p = 0.007). A significant association was observed between inadequate liver store of retinol and death by ischemic CVD (G1) (p = 0.001) with an odds ratio of 10.38. It was observed that individuals with higher body weight and liver weight showed lower liver store of retinol with significant differences (p = 0.027 and p = 0.026). Conclusion Ischemic CVD and increased body weight and liver weight are related to a greater impairment of the liver store of retinol.
