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. The goal was to determine whether heart failure associated skeletal muscle blood flow abnormalities were affected by loss of a functioning 5-HT7 receptor in skeletal muscle vasculature.
