Image: PD 1. Low serum 25-hydroxy vitamin D (25(OH)D) levels were associated with coronary heart disease events in Caucasians and Chinese participants.  2. Low serum 25-hydroxy vitamin D (25(OH)D) levels were not associated with coronary heart disease events in Black or Hispanic participants.  Evidence Rating Level: 2 (Good)  Study Rundown: Previous studies have...
Image: PD 1. Intensive lifestyle intervention in overweight and obese patients with type II diabetes reduced weight, hemoglobin A1c levels, and improved many risk factors for cardiovascular disease.  2. Intensive lifestyle intervention in overweight and obese patient did not significantly affect a cardiovascular events.   Evidence Rating Level: 1 (Excellent)  Study Rundown: This is the...
Image: PD 1. The EVAR I trial compared the safety and efficacy of endovascular and open abdominal aortic aneurysm repair 2. There were no significant differences in all-cause mortality between the two groups. 3. The endovascular group experienced significantly higher rates of graft-related complications and reinterventions. Original Date of Publication: May 20, 2010 The...
Image: PD 1. Rates of mental stress-induced myocardial ischemia (MSIMI) were significantly lower in patients taking escitalopram (Lexapro) vs. placebo at the end of 6 weeks. 2. Rates of exercise-induced myocardial ischemia (ESIMI) were not significantly reduced in patients taking escitalopram vs. placebo at the end of 6 weeks. Evidence Rating Level:...
Image: PD 1. Dual-chamber implantable cardioverter-defibrillators (ICDs) do not offer better outcomes with regard to mortality or readmission in the year following transplant.  2. Dual-chamber ICDs are associated with higher complication rates relative to single-chamber ICDs including increasing risk of complications requiring surgical revision.  Evidence Rating Level: 2 (Good)  Study Rundown: More complex...
Image: PD 1. Patients with heart failure, chronic kidney disease, and hypertension demonstrate increased chemosensitivity in the carotid body, contributing to increased sympathetic activation. 2. Degree of autonomic dysregulation correlated with functional status and mortality. 3. In animal and human models, removal of the carotid body “reset” the sympathetic activation and improved vascular tone. Primer: The carotid body, a highly...
