MRCP2-3571

An 82-year-old man with a history of congestive cardiac failure presented to accident and emergency with symptoms of an acute ischaemic stroke. He had slurred speech, left sided facial droop, and some loss of fine motor control in the left hand. Upon admission, his blood pressure was 185/70 mmHg and his heart rate was 95 beats per minute in sinus rhythm. The initial CT scan of his brain revealed evidence of chronic small vessel ischaemia but no acute pathology, including no haemorrhage. What combination of investigations should be conducted during his acute admission?
