The first ischemic changes in the EEG are detected an average of 6.5 seconds after circulatory arrest. With prolongation of the cerebral ischemia, progression to isoelectricity occurs within 10 to 20 (mean 15) seconds from the onset of cardiac arrest.18-21

The ischemic heart disease may be either absolute (e.g., coronary artery disease) or relative (e.g., cardiomyopathy with a greatly enlarged heart). An exam for ischemic heart disease should use the HEART worksheet and the inform in section 7.4. 7.6 What additional information would be useful in a disability examination for arrhythmias?

An ischemic stroke is caused by narrowing of a cerebral blood vessel, the narrowing being the result of a thrombus, an embolism, or hypoperfusion.60,61 The thrombotic causes of ischemic stroke are:60 1) Atherosclerosis; 2) Vascultis; 2) Arterial dissection; 4) Polycythemia; 5) Hypercoaguable states, and; 6) Infections such as HIV and ...

A stroke can be caused by: 1) A blood clot that travels from the peripheral circulation and lodges in a blood vessel in the brain, or; 2) A ruptured blood vessel. The first type of stroke is called an ischemic stroke and it is the more common of the two. The second type is called a hemorrhagic stroke.

One of the most prominent reasons underlying an ischemic event is a thrombus formation in a blood vessel. Insufficient provision with oxygen means that tissues become hypoxic, or, if no oxygen is supplied at all, anoxic, a condition that, if prevailing for too long will cause necrosis (i.e. cell death).

In an ischemic stroke, a blood vessel carrying blood to the brain is blocked by a blood clot. In a hemorrhagic stroke, the blood vessel breaks open and blood leaks into the brain. The causes of stroke include high blood pressure, age, family history, smoking, diabetes, high cholesterol, heart disease, and some medications like birth control pills.

CT may fail to show small ischemic strokes in the posterior fossa because of bone artifact; small infarcts on the cortical surface may also be missed. Contrast-enhanced CT54 scans add specificity by showing contrast enhancement of subacute infarcts and allow visualization of venous structures.
