Blood flow to the heart muscle is normally regulated by microscopic arteries in the heart. To control
the blood flow, these microscopic arteries are able to change their size, thus either increasing or
reducing blood flow to meet the demands of the heart. In many people these microscopic arteries
are dysfunctional, called “microvascular dysfunction”, leading to symptoms and worse heart
outcomes. In patients it is possible to estimate the function of these microscopic heart arteries
during an angiogram procedure using specialised wires inserted into the heart. However, this does
not give any information about the underlying cause of dysfunction. Indeed, very little is known
about the mechanisms that leading to microvascular dysfunction despite this being a common
condition.
This research study is designed to investigate the causes of microvascular dysfunction. It is
possible to isolate microscopic heart arteries from excess heart muscle left over after open heart
surgery, and then directly measure their function in a laboratory. In this way we can better
understand how their function is related to factors such as co-existing medical conditions or
biomarkers in the blood. A better understanding of how microscopic heart arteries function and
what causes them to dysfunction will enable us to develop new therapies and tests to diagnose and
treat patients with microvascular dysfunction.

You can take part if:



You may not be able to take part if:


Severe epicardial coronary artery disease which prevents accurate assessment of microvascular function Pregnancy confirmed in medical records or detected as part of routine screening before surgery or as part of Ionising Radiation (Medical Exposure) Regulations (IRMER). HIV, Hepatitis A, B or C infection confirmed in the patient’s available medical records. Patients who have a history / current diagnosis of cancer or who have received / are receiving chemotherapy or radiotherapy. Any impediment to communication which, in the opinion of the investigator, might prevent the investigator communicating effectively with the patient during the study (including inability to speak English).
