Biography
Dr Graham Cole is a consultant cardiologist primarily based at Hammersmith Hospital. He has broad expertise in assessing patients with shortness of breath, chest pain, palpitations, dizziness, collapses and ankle swelling. He also has expertise in assessing cardiovascular risk and assessing patients needing surgery to minimise their risk.
He is a sub-specialist in cardiac imaging, being extensively trained and accredited in using modern techniques (echo, cardiac MRI, cardiac CT) to investigate patients painlessly and non-invasively. He has additional expertise in heart failure.
Dr Cole qualified from Gonville & Caius College, University of Cambridge in 2005, achieving a first class honours degree in natural sciences. He went on to achieve distinctions in every area of his final medical examinations at Cambridge. He subsequently completed the Hammersmith medical rotation as a junior doctor followed by a further decade of specialist cardiology training in the prestigious north west Thames rotation. This included a four-year fellowship in cardiac MRI at the world-leading Heart Hospital Imaging Centre under Prof James Moon, the London CT fellowship and a PhD in echocardiography.
Highlights of Dr Cole’s research include developing ways to help patients make individualised decisions about the pros and cons of different treatments, and developing imaging techniques to be able to make precise diagnoses and know when a patient’s condition has changed.
