According to a study by researchers at Johns Hopkins, heart transplant patients are considerably more likely to survive at least a decade after their operation if they underwent the procedure before the age of 55 at a hospital that performs at least 9 heart transplants per year. The study is published in the March issue of The Annals of Thoracic Surgery. The researchers analyzed data collected by the United Network of Organ Sharing (UNOS) from over 22, 000 adults in the U.S. who underwent heart transplant between 1987 and 1999. They found that 10 years after transplantation, approximately half of all patients were still alive. In addition further examination identified factors that seem to predict at least 10 years of life following the procedures. Arman Kilic, M.D., a surgical resident at The Johns Hopkins Hospital and leader of the study explained: "There are 2, 000 to 2, 500 heart transplants a year in the U.
Scientists modified a protein in the heart which dramatically reduced cell damage after heart attacks, according to new research published the American Heart Association journal Arteriosclerosis, Thrombosis and Vascular Biology. The modified protein reduced cell damage by 50 percent in mice without causing harmful inflammation, the researchers found. Those results came during research looking at ways to prevent heart failure induced by heart attack. The protein is called focal adhesion kinase, or FAK. It organizes cell structure by activating various processes that help the cells stay alive. "FAK is important for basic processes in all cells, and it appears to be important for cell survival, growth and migration in a number of cell types, but is especially critical in the heart, " said Joan Taylor, Ph.
Blood and urine markers can indicate which patients with an abrupt kidney injury following heart surgery will experience progressive kidney problems, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN). Testing for these markers soon after surgery could help doctors protect the health of patients' kidneys. Acute kidney injury (AKI), an abrupt or rapid decline in kidney function, is an increasingly prevalent condition. Sometimes AKI arises following heart surgery because the kidneys are deprived of normal blood flow for extended periods of time during the procedure. In most cases, AKI after heart surgery resolves quickly, but some cases worsen and can seriously affect patients' health and survival. Until now, doctors have not been able to determine which cases of AKI that develop after heart surgery will worsen.
About 350, 000 Canadians suffer from atrial fibrillation, according to estimates of the Canadian Heart and Stroke Foundation. A new study, in the current issue of the Canadian Medical Association Journal (CMAJ), shows a strong link between an irregular heartbeat or atrial fibrillation (AF), and a higher risk of dementia. The new study supports previous evidence that AF increases the risk of dementia amongst stroke survivors; however, it discovered that the link also applies to those with AF who have not suffered a stroke. According to the researchers of the Population Health Research Institute (PHRI) at McMaster University, the study offers prospective evidence that atrial fibrillation raises the chances of cognitive decline and dementia, regardless of clinically overt stroke and baseline cognitive function.
An initial genetic analysis of a 5, 000-year-old mummy that has become known as Oetzi the Tyrolean Iceman, reveals he was predisposed to cardiovascular diseases. The finding appears to be confirmed by the fact scientists also found that Oetzi, the world's oldest glacier mummy, had arteriosclerosis, or hardening of the arteries. You can read the latest findings on Oetzi's physiognomy, ethnic origin and predisposition towards illness in the 28 February issue of Nature Communications. Oetzi, described as a "5, 300-year-old Copper age individual", was found on the Tisenjoch Pass in the Italian part of the Oetztal Alps in 1991, by tourists. His well-preserved, mummified remains are now at the South Tyrol Museum of Archaeology in Bolzano, South Tyrol, Italy. Estimates suggest that at the time of his abrupt death, this Neolithic man was 45 years old, stood about 1.
