Association of vascular endothelial function and quality of life in patients with ischemia and non-obstructive coronary artery disease.

Improvements are required in the quality of life (QoL) of patients with ischemia and non-obstructive coronary artery disease (INOCA). Several patients with INOCA experience vascular endothelial dysfunction. However, the relationship between endothelial function and QoL remains unelucidated.
