IHSA is proud to have the following clinicians working with and supporting us.

“The International Heart Spasm Alliance has an important role in the management of coronary vasospasms and microvascular angina by providing helpful information to affected patients. Moreover, their activities increase community awareness of these disabling disorders, since they are more common than currently realized.”

- Prof. John Beltrame

“I support education and research to improve the wellbeing of patients with ischaemic heart disease. Coronary spasm is under-recognised and an important cause of angina and sometimes heart attack. The International Heart Spasms Alliance is a welcome development.”
