Angry Cognitive Decline in Heart Bypass Patients

This study is too advanced for those like Bev who do not understand the circulation of the blood and those like her who have not read the thread. The surgeries in this paper were rather minor like the one that caused Fred to have serious mental problems.

None of these surgeries were for ruptured aneurysms where the aorta was cut on rather than merely being pierced for the heart lung machine. This kind of surgery is hundreds of times more likely to cause brain damage. Steele was violent when he woke up from the respirator. He demanded that his wife come to the hospital immediately or he would divorce her. This is a predictor of permanent brain damage.

Here again are Bev's curious beliefs about the circulation of the blood.

I don't know if you know what the aorta does but it carries blood from the heart and down to the stomach before pumping it round the body.

Longitudinal Assessment of Neurocognitive Function after Coronary-Artery Bypass Surgery
.........
(Coronary Artery Bypass Graft)

Our data demonstrate a significant association between cognitive decline immediately after CABG surgery and both the incidence and the severity of cognitive decline five years later. This association indicates that because of perioperative injury, increased susceptibility to such injury, or decreased ability to recover from it, patients with perioperative decline are at increased risk for long-term cognitive decline. Determining how this decline compares with any changes in cognitive function that occur in a population of similar age and state of health who have not undergone CABG would require a prospective longitudinal study that included the latter group. Studies of elderly subjects have demonstrated a gradual decline in neurocognitive function with age.15,20-22 In most investigations, genetic and environmental factors have been shown to interact to affect the progression of cognitive decline related to aging. Our data indicate that cardiac surgery with cardiopulmonary bypass is an additional factor that can alter this progression.
