Acute necrotizing eosinophilic myocarditis in a patient taking Garcinia cambogia extract successfully treated with high-dose corticosteroids.

A previously healthy 48-year-old woman was evaluated for lightheadedness and chest heaviness 2 weeks after starting the herbal supplement Garcinia cambogia. She was found to be hypotensive and had an elevated serum troponin level. The patient had a progressive clinical decline, ultimately experiencing fulminant heart failure and sustained ventricular arrhythmias, which required extracorporeal membrane oxygenation support.

A comparison of the use of traditional hand injection versus automated contrast injectors during cardiac catheterization.

Objective: To compare the incidence of contrast-induced nephropathy (CIN) and vascular complications in patients undergoing cardiac catheterization using traditional manual contrast injection techniques with those in which an automated contrast injector device was used.

Background: It has been suggested that use of automated contrast injectors in coronary interventions could reduce complications by reducing contrast volume usage and allowing the use of smaller sheaths.

Methods: This was a retrospective cohort study with review of patient's electronic medical charts and the Heartbase registry.
