Dual Antiplatelet Therapy with Aspirin and Clopidogrel for Acute High Risk Transient Ischemic Attack and Minor Ischemic Stroke
What is the role of dual antiplatelet therapy after high risk transient ischemic attack or minor stroke? Specifically, does dual antiplatelet therapy with a combination of aspirin and clopidogrel lead to a greater reduction... read more
The Myth of Vasopressors and Ischemia
Despite the widespread clinical use, and their well-documented life-saving properties, vasopressors are often maligned, accused of causing ischemia to fingers, toes, mesentery, kidneys, and so forth. Not only is the evidence... read more
Cerebral Autoregulation in the Prediction of Delayed Cerebral Ischemia and Clinical Outcome in Poor-Grade Aneurysmal Subarachnoid Hemorrhage Patients
High initial pressure reactivity index, presumably reflecting early brain injury, but not oxygen reactivity index, was associated with delayed cerebral ischemia and worse clinical outcome in poor-grade subarachnoid hemorrhage... read more
Cardiovascular Testing and Clinical Outcomes in Emergency Department Patients With Chest Pain
In patients who present to the emergency department with chest pain without evidence of ischemia, is cardiac testing - noninvasive testing or coronary angiography - associated with changes in revascularization or acute myocardial... read more

A 68-year-old female presents to the ED with abdominal pain, bloating, and nausea which she states began this morning upon wakening about 3 hours prior to arrival. She appears moderately uncomfortable and pale. She is urgently... read more
Cellular Mechanisms of Prevention of Ischemia-Reperfusion Injury
Ischemic preconditioning is the phenomenon whereby brief periods of sublethal ischemia protect against a subsequent, more prolonged, ischemic insult.... read more
