Carbon monoxide may cause long-lasting heart damage
01-29-2008 · EurekAlert!Findings of a study by researchers at Rhode Island Hospital suggests that heart damage caused by carbon monoxide may have long-lasting effects even after the toxic gas has been eliminated from the blood.

- Many heart attack patients still not getting emergency clot-busting treatment
08-03-2007 · EurekAlert!
Far more of today's heart attack patients receive emergency angioplasty treatment or clot-busting drugs to reopen their clogged heart arteries than even a decade ago, a new study finds. But 10 percent of patients who could benefit from this urgent treatment -- which is known to save lives and prevent lasting damage to the heart muscle -- don't get it at all, the study shows.

- Faulty cell membrane repair causes heart disease
07-03-2007 · EurekAlert!
During vigorous exercise, heart muscle cells take a beating. In fact, some of those cells rupture and without an efficient repair process those cells would die and cause heart damage (cardiomyopathy). University of Iowa researchers have discovered a specific repair mechanism in heart muscle and identified a protein called dysferlin that is critical for resealing heart muscle cell membranes.

- Cell wall of pneumonia bacteria can cause brain and heart damage
10-23-2006 · EurekAlert!
Investigators at St. Jude Children's Research Hospital have discovered in mouse models how cell walls from certain pneumonia-causing bacteria can cause fatal heart damage; researchers have also shown how antibiotic therapy can contribute to this damage by increasing the number of cell wall pieces shed by dying bacteria.

- Carbon monoxide counteracts one side-effect of an anti-cancer drug
11-21-2007 · EurekAlert!
Doxorubicin (DOX) is a red-colored anti-cancer drug that carries serious side effects for the heart. These cardio-toxic effects are due to inhibition by DOX of mitochondrial biogenesis, a term used to describe cellular energy generation. In a new study, it is now shown that mitochondrial biogenesis can be recovered in DOX-treated rodents by either inhalation of carbon monoxide or overexpression of the protein HO-1.

- Severe heart attack damage limited by hydrogen sulfide
09-18-2007 · EurekAlert!
Heart attacks and even surgery can cause severe heart-tissue and cell damage due to oxygen deprivation. A new study finds that hydrogen sulfide can prevent such damage after blood flow is restored.

- Short-term studies suggest that whole grain oats may reduce risk factors for coronary heart disease
04-17-2007 · EurekAlert!
Trials lasting four to eight weeks indicate that including whole grain oats in your diet may lower total and low-density lipoprotein cholesterol. Coronary heart disease (CHD) is a major cause of death and ill health. One of the risk factors for CHD is elevated blood levels of total cholesterol and of low density lipoprotein cholesterol. Existing observational studies indicate that wholegrain cereals may reduce the risk of CHD, possibly by reducing cholesterol levels.

- Carbon monoxide protects lung cells against oxygen-induced damage
01-18-2007 · EurekAlert!
Researchers at the University of Pittsburgh have demonstrated that low-dose carbon monoxide administered in conjunction with oxygen therapy markedly inhibits oxygen-induced damage to lung cells. These findings, being reported in the January 19 issue of the Journal of Biological Chemistry, have significant implications for the treatment of acute respiratory distress syndrome, or ARDS, according to the study's authors.

11-17-2006 · EurekAlert!
A new study shows that blood flow to the legs is relatively normal in people with diastolic heart failure, suggesting other potential causes of their inability to do everyday activities, according to researchers at Wake Forest University Baptist Medical Center.
