Sometimes patients experience chest pain, but the blood vessels supplying the heart look normal on scans such as CT Coronary Angiogram, or even Catheter Coronary Angiogram. However, this does not automatically exclude the blood vessels as the cause. There is increasing understanding that the small branches of blood vessels may malfunction and constrict, reducing blood flow, oxygen and nutrients to the heart muscle. This is called “Microvascular Ischaemia”. This is common in patients with Diabetes, and Metabolic Syndrome. Treatment does not require surgery, and often medications can relieve the symptoms.
