Calorie, Fat Consumption Up Among Statin Users

Calorie and fat consumption increased significantly from 1999 to 2010 among statin users — but not among nonusers — according to a JAMA Internal Medicine study. The researchers conclude that “the importance of dietary composition may need to be reemphasized for statin users.” The researchers evaluated 24-hour dietary recall data from nearly 28,000 adults participating in […]

Study Details Cardiovascular Events in Cannabis Users

One quarter of cardiovascular events among young cannabis users might be fatal, according to a small study in the Journal of the American Heart Association. Researchers examined 35 cardiovascular events (1.8% of roughly 2000 adverse events) in cannabis users reported to the French Addictovigilance Network from 2006 to 2010. Nearly half the patients reported using cannabis […]

Azithromycin, Levofloxacin Linked to Increased Risks for Arrhythmia and Mortality Compared with Amoxicillin

Azithromycin and levofloxacin carry higher arrhythmia and mortality risks than amoxicillin, according to an observational study in the Annals of Family Medicine. The FDA issued a cardiac warning on azithromycin in March 2013. Researchers studied nearly 1.8 million U.S. veterans (mean age, 57) who received outpatient prescriptions for one of the three antibiotics from 1999 to […]
