FDA Approves Barostim Neo System for Advanced Heart Failure Patients. Similar to a pacemaker, the Barostim Neo System uses a pulse generator implanted below the collar bone with a lead that attaches to the carotid artery in the neck. It delivers electrical impulses to baroreceptors in the neck, which sense how blood is flowing through the carotid arteries and relays information to the brain. The brain, in turn, sends signals to the heart and blood vessels that relax the blood vessels.

Similar to a pacemaker, the Barostim Neo System uses a pulse generator implanted below the collar bone with a lead that attaches to the carotid artery in the neck. It delivers electrical impulses to baroreceptors in the neck, which sense how blood is flowing through the carotid arteries and relays information to the brain. The brain, in turn, sends signals to the heart and blood vessels that relax the blood vessels and inhibit the production of stress-related hormones to reduce heart failure symptoms.

Hormone Therapy Linked to Heart Fat, Hard Arteries

Not all heart fat is equal. Buildup in the pericardium is more strongly associated with heart disease, and seems to increase as estrogen levels drop during menopause. This new study shows that a certain type of hormone replacement therapy could exacerbate the problem, while others may be protective. Image courtesy of Rick Sciullo/UPMC.
