Background: Cardiovascular autonomic neuropathy is a major complication in patients with diabetes mellitus (DM). However, the relationship between cardiovascular autonomic neuropathy and the incidence of cardiovascular events has been poorly investigated in type 2 DM. The present study aimed to assess the long-term cardiovascular predictive value of baroreflex sensitivity (BRS) in Japanese patients with type 2 DM without structural heart disease. Methods and Results: BRS was evaluated using the phenylephrine method in 210 patients with type 2 DM who did not have structural heart disease or other severe complications. BRS was considered depressed if <6 ms/mmHg. Accurate follow-up information for 3-10 years (mean 4.7 years) was obtained in 184 patients (90 females, 94 males; mean age 58±12 years). The initial onset of a major adverse cardiovascular event (MACE) was investigated. During follow-up, 19 patients presented with a MACE (4 cardiovascular deaths, 3 nonfatal myocardial infarctions, 4 coronary revascularizations, 5 strokes, 2 congestive heart failures). Cox proportional hazards regression analysis revealed that depressed BRS was independently associated with the incidence of MACE (hazard ratio 1.93, 95% confidence interval 1.09-3.82, P=0.0236). Conclusions: Depressed BRS at baseline has long-term cardiovascular predictive value in Japanese patients with type 2 DM without structural heart disease. (Circ J 2010; 74: 1379 - 1383)

It has been demonstrated the involvement of branched-chain amino acids (BCAA) on obesity and related metabolic disorder. We investigated the effects of branched-chain amino acids (BCAA) on obesity and on glucose/fat homeostasis in mice fed on a high-fat (45%) diet. BCAA was dissolved in 0.5% methylcellulose and added to the drinking water (BCAA-treated group). A high-fat diet was provided for 6 weeks and BCAA was given for 2 weeks. The BCAA-treated group gained almost 7% less body weight and had less epididymal adipose tissue (WAT) mass than the control group (ppp<0.05). These results demonstrate that the liver and muscle TG concentration are less in BCAA-treated group. BCAA affects PPAR-alpha and UCP expression in muscle and liver tissue.
