Abstract 4141446: Sodium Glucose Co-transporter 2 (SGLT2) Inhibitors Promote Resiliency to High Pressure Stress in the Human Microvasculature

Circulation

Circulation, Volume 150, Issue Suppl_1 , Page A4141446-A4141446, November 12, 2024. Emerging evidence suggests that vascular stress from cardiovascular-related co-morbidities promotes microvascular dysfunction, a key component in the development of heart failure with preserved ejection fraction.

The 5-HT7 receptor contributes to increased hindquarter blood flow caused by skeletal muscle contraction.

Journal of Cardiovascular Pharmacology

Serotonin (5-hydroxytryptamine, 5-HT) at low plasma concentrations reduces blood pressure and dilates some skeletal muscle arterioles in the rat. We conclude that 5-HT acting at least in part via the 5-HT7 receptor may have a larger role in (patho)physiological regulation of the circulation than has been heretofore appreciated.
