A related study by Selnes et al. [7] concluded patients with coronary artery bypass grafting did not differ from a comparable nonsurgical control group with coronary artery disease 1 or 3 years after baseline examination. This finding suggests that late cognitive decline after coronary artery bypass grafting previously reported by Newman et al ...
Endomyocardial biopsy (EMB) is an invasive procedure used routinely to obtain small samples of heart muscle, primarily for detecting rejection of a donor heart following heart transplantation. It is also used as a diagnostic tool in some heart diseases .
At 5 years post-transplant, 80% of lung transplants, 60% of heart transplants and 50% of kidney transplants are affected, while liver transplants are only affected 10% of the time. [20] Therefore, chronic rejection explains long-term morbidity in most lung-transplant recipients, [ 23 ] [ 24 ] the median survival roughly 4.7 years, about half ...
A beating heart awaiting transplant. American medical researcher Simon Flexner was one of the first people to mention the possibility of heart transplantation. In 1907, he wrote the paper "Tendencies in Pathology," in which he said that it would be possible one day by surgery to replace diseased human organs – including arteries, stomach, kidneys and heart.
Less commonly, PTLD occurs after hematopoietic stem cell transplantation. The incidence varies by the type of transplantation: the lowest rates are seen with bone marrow transplants and liver transplants. The highest rates of PTLD are seen with lung and heart transplants, which is primarily due to the need for higher levels of immunosuppression.
A sleep study is a test that records the activity of the body during sleep. There are five main types of sleep studies that use different methods to test for different sleep characteristics and disorders. These include simple sleep studies, polysomnography, multiple sleep latency tests (MSLTs), maintenance of wakefulness tests (MWTs), and home ...
Myocardial stunning or transient post-ischemic myocardial dysfunction is a state of mechanical cardiac dysfunction that can occur in a portion of myocardium without necrosis after a brief interruption in perfusion, despite the timely restoration of normal coronary blood flow.
A constant routine protocol is a common method used in human circadian rhythm research to study internally generated, or endogenous, circadian rhythms without the effect of external, or exogenous, influences. In the method, subjects are kept in constant conditions for at least 24 hours. [1]
