As published in Obesity, a J-shaped association between adiponectin level and heart failure exists. The study involved 787 males with heart failure and 787 healthy controls from the Physicians’ Health Study. The relative risk of heart failure from lowest to highest quintile of adiponectin level was 0.74, 0.67, 0.70, and 0.92.
Read the article summaryAs published in the European Journal of Clinical Investigation, fasting serum apo B-48 levels were elevated in patients with Coronary Artery Disease (n=96; 6.9 µg/mL) compared to patients without CAD (n=67; 3.9 µg/mL). Along with other cardiac risk factors, an apo B-48 level > 4.34 µg/mL was predictive of CAD.
Read the article summaryAs published in Diabetic Medicine, cardiac autonomic neuropathy can be predicted in patients with T2DM and negative exercise echocardiograms based on post-exercise heart rate recovery. Of the 135 study subjects, 27 (20%) had cardiac autonomic neuropathy, the criteria for which included > 2 of 7 autonomic function markers (4 cardiac reflex tests and 3 indices of short-term heart rate variability). The optimal cut-offs for post-exercise heart rate recovery at 1-, 2-, and 3-minutes were < 28, < 50, and < 52 beats per minute, respectively.
