Abstract

Diabetes is accompanied by abdominal obesity, which produces various metabolic abnormalities. While metabolic factors have been considered to promote the development of coronary atherosclerosis in the early-stage of diabetes, it remains unknown whether the presence of obesity in early-stage diabetics affects the natural history of coronary atherosclerosis. We herein investigated the characteristics of the disease substrate in obese early-stage diabetics. The DIANA (DIAbetes and diffuse coronary NArrowing) study was a serial evaluation of angiographic disease progression in early-stage diabetics with coronary artery disease. A total of 252 study subjects were stratified into non-obese (n=168) and obese groups (n=84). Obesity in Japanese subjects was defined as a body mass index ≥25 kg/m(2) according to the statement about Japanese obesity from the Japan Society for the Study of Obesity. Coronary atherosclerotic changes were evaluated by a quantitative computed analysis. The total lesion length (TLL=total length of all atherosclerotic lesions) was compared between the groups. The obese patients were younger (p=0.0002) and had higher levels of fasting (p=0.002) and postprandial insulin (p=0.01), and higher triglyceride levels (p=0...Continue Reading

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
