Renal Denervation: A New Therapy for Resistant Hypertension.

The Food and Drug Administration (FDA) recently approved renal denervation to treat resistant hypertension. This procedure is a minimally invasive procedure that starts by placing a catheter in the renal artery. This catheter is used to send either radiofrequency heat or ultrasound waves to burn the superficial nerves surrounding the renal arteries while making certain no damage happens to the renal arteries themselves.

Chelation Therapy in Coronary Artery Disease: Fact or Fiction?

Coronary artery disease (CAD) is responsible for 690,000 deaths a year, a leading cause of mortality worldwide. CAD results from cholesterol plaque buildup in arteries. Chelation therapy, which uses ethylenediaminetetraacetic acid to remove toxic metals from the bloodstream, has been explored as an alternative treatment for atherosclerotic CAD.
