The correlation between visceral fat area, lipid level and coronary heart disease in the elderly

Objective To investigate the correlation between visceral fat area, blood lipid level and coronary heart disease. Methods A total of 139 old people(aged ≥ 60 years) participated in physical examination in rural areas of Guangde, Anhui province in April 2018 were selected. Combined with the careful inquiry of the history of coronary heart disease in the local primary medical records, 57 physical examinee diagnosed with coronary heart disease were enrolled into coronary heart disease group(CHD), and the remaining 82 physical examinee were enrolled into the non-coronary heart disease group(NC). Venous blood was drawn on an empty stomach in the morning to determine the levels of total cholesterol, triglyceride, low density lipoprotein cholesterol and high density lipoprotein cholesterol. Ask client to remove crown, shoes, fasting, wearing only single clothing to measure height and weight. The obesity related indexes, visceral fat area, body fat rate, body fat content, body fat, body mass index were measured using Inbody S10 body composition analyzer based on the principle of bioelectrical impedance. The correlation between visceral fat area, lipid level and coronary heart disease were analyzed. Results The levels of visceral fat area, other obesity-related indicators and blood low density lipoprotein cholesterol in the CHD group were higher than those in the NC group. Regression analysis showed that those with increased visceral fat area and those with high low-density lipoprotein cholesterol blood level had an increased risk of coronary heart disease, which was 4.052 times and 2.348 times of that of the NC group, respectively. Correlation analysis showed that visceral fat area was positively correlated with serum triglyceride level. Conclusion Visceral fat area and low density lipoprotein cholesterol are closely related to coronary heart disease. Visceral fat area and other obesity indicators are significantly higher in elderly coronary heart disease individuals than in non-coronary heart disease individuals. When visceral fat area is increased or low density lipoprotein cholesterol is high, the risk of coronary heart disease in the elderly is significantly higher. With the increase of visceral fat area, blood triglyceride level increases. Therefore, the principle of bioelectrical impedance can be used to analyze the related indicators of obesity in the elderly and dynamically monitor the prevention and prognosis of coronary heart disease in combination with the level of blood lipid.
