COVID-HEART study CMR protocol. The full protocol takes approximately an hour, and comprises (in order of acquisition): localisers and axial HASTE stack, cine images of the left ventricle in long-axis views, pre-contrast T1 mapping and T2 mapping, rest myocardial perfusion after injection of 0.05 mmol/kg of gadolinium based contrast agent (GBCA) followed immediately with 0.1 mmol/kg top-up (giving a total dose of 0.15 mmol/kg). Then a ventricular short-axis stack and aortic cine images (aortic distensibility, followed by late gadolinium enhancement (LGE) imaging and post-contrast T1 mapping. The last component (dependent on patient suitability) is stress perfusion imaging, performed after administration of adenosine stress at dose of 140-210mcg/kg/min, utilising a further 0.05 mmol/kg of GBCA
