Abstract: | The relationship between disturbances of hemostasis, blood insulin, and type of obesity was studied in nonobese subjects and in obese subjects with different body fat distribution under the conditions of postprandial lipemia (after a single standard fat load). In total, 44 subjects (16 men and 28 women aged 18–58) were divided into three groups according to the presence and type of obesity: a group with normal body weight, a group with abdominal obesity, and a group with gluteofemoral obesity. In abdominal obesity, triglyceride clearance was low and insulin secretion after a fat load was abnormally prolonged over 6 h; consequently, fibrinolysis decreased. Hemostasis disturbances in the obese subjects were aggravated by increased fibrinogen. Thus, a combination of metabolically associated disturbances (hypertriglyceridemia, hyperinsulinemia, and hypofibrinolysis) increases considerably the risk of coronary heart disease (CHD) in obese subjects, especially, in those with abdominal obesity. |
