Effects of erythritol on endothelial function in patients with type 2 diabetes mellitus: a pilot study.

Sugar substitutes are important in the dietary management of diabetes mellitus. Erythritol is a non-caloric dietary bulk sweetener that reverses endothelial dysfunction in diabetic rats. We completed a pilot study to examine the effects of erythritol on vascular function in patients with type 2 diabetes mellitus.

Peripheral artery disease is associated with severe impairment of vascular function.

Patients with peripheral artery disease (PAD) have higher cardiovascular event rates than patients with established coronary artery disease (CAD) and abnormal endothelial function predicts cardiovascular risk in PAD and CAD. We investigated the hypothesis that PAD is associated with a greater degree of impairment in vascular function than CAD. We used several non-invasive tests to evaluate endothelial function in 1320 men and women with combined PAD and CAD (n = 198), PAD alone (n = 179), CAD alone (n = 466), or controls aged > 45 years without CAD or PAD (n = 477).

Effects of labetalol on hemodynamic parameters and soluble biomarkers of inflammation in acute coronary syndrome in patients with active cocaine use.

Cocaine use is associated with increased cardiovascular mortality and can promote acute coronary syndrome (ACS). Use of beta-blockers is controversial in patients who use cocaine, and the safety and efficacy of these medications in ACS in patients actively using cocaine is unknown. We enrolled 90 patients with ACS and positive urine drug screen for cocaine.

Usefulness of elevations in serum choline and free F2)-isoprostane to predict 30-day cardiovascular outcomes in patients with acute coronary syndrome.

Our objectives were to evaluate the prognostic value of several biomarkers in patients with acute coronary syndrome (ACS) through an evaluation of the 30-day clinical outcomes. Multiple biomarkers have emerged as potentially useful in risk stratification of ACS. Specifically, markers of vascular inflammation and oxidative stress might be helpful in the determination of clinical outcomes.

MRSA-associated bacterial myocarditis causing ruptured ventricle and tamponade.

We report a case of an 81-year-old man with bacterial myocarditis presenting with elevated troponins and sepsis, who succumbed due to a ruptured ventricle. The infecting organism was found to be methicillin-resistant Staphylococcus aureus. Bacterial myocarditis is a rare occurrence when independent of infective endocarditis.
