In a new study out of University of California San Diego School of Medicine, researchers found a drug used for heart failure improves symptoms associated with postural orthostatic tachycardia syndrome, otherwise known as POTS. This complex, debilitating disorder affects the body’s autonomic nervous system, causing a high heart rate, usually when standing.
Writing in the February 15, 2021 online issue of the Journal of the American College of Cardiology, study authors investigated the drug ivabradine and its effects on heart rate, quality of life and plasma norepinephrine levels in persons living with POTS. Norepinephrine is a stress hormone and neurotransmitter. In blood plasma, it is used as a measure of sympathetic nervous system activity. Trial participants experienced a reduction in heart rate, improvement in their symptoms and overall quality of life one month after taking the drug.
Still progressing, but a little setback.
