Clinical trials: Microvascular Obstruction
Microcirculation
Effect of Cupping Therapy on Microcirculation in Healthy Volunteers
Twenty healthy volunteers were included in the study. The NIRS was placed on the thenar region of the hand. The vascular occlusion protocol had been done before and after cupping therapy (CT).

Myocardial Injury, Atherosclerosis Cardiovascular Disease
Multimodal Biomarkers in Coronary Artery Disease Pathogenesis: The Oxford Acute Myocardial Infarction Study (OXAMI Study)
Coronary artery disease is one of the most common causes of illness and death. It develops when fatty deposits, known as plaques, build up in the arteries that supply blood to the heart.

Microcirculatory Dysfunction, Tissue Hypoperfusion
Submental Tissue Oxygenation and Arterial Lactate in Major Surgery
During major surgical procedures performed under general anesthesia, changes in blood flow and oxygen delivery to tissues may occur due to blood loss, hemodynamic fluctuations, and anesthesia-related physiological effects.
