People who have had stroke or transient ischemic attacks require brain imaging to ascertain the extent of the carotid artery narrowing, says the U.K.'s NICE. If symptoms of TIA have subsided in these patients, a specialist should first assess the person to determine the necessity of brain imaging. MRI tests and CT scans for ischemia help to provide evidence for early signs of bleeding, infarction or vessel thrombosis, notes the American Heart Association.
Doctors should carry out complete blood counts on all patients suspected to have ischemic stroke in order to exclude alternative diagnoses such as hypoglycemia. The blood count should include tests such as platelet count, cardiac markers and prothrombin time, says the AHA. Elevated cardiac markers, for instance, signify increased severity of stroke and mortality risk.
