Eating raw walnuts alongside your high-fat meal may help protect arteries from short-term damage. Olive oil did not offer the same benefits as walnuts did for the vascular structure. Researchers from the University of Barcelona’s Hospital Clínico first reported this study in the Oct. 17, 2006 edition of the Journal of the American College of Cardiology.

"People would get the wrong message if they think that they can continue eating unhealthy fats provided they add walnuts to their meals," said Emilio Ros, MD, PhD, director of the Lipid Clinic at Hospital Clínico in Barcelona, Spain, the primary location where the study was completed. "Instead, they should consider making walnuts part of a healthy diet that limits saturated fats.

Plavix Sales To Soar Due To Faulty Heart Stents

Plavix Sales To Soar Due To Faulty Heart Stents

Recent studies have shown the new generation of drug-eluting heart stents to be associated with an increased risk of late stent thrombosis, cardiac mortality, myocardial infarction, and all cause mortality. And at the same time, they have proven to be little more effective, if any, than the older bare-metal stents that sell for a fraction of the cost.

Due to the discovery of all of these increased risks, experts are now predicting that patients who received the drug eluding stents will be required to take the expensive blood-thinning drug Plavix for life.

In a few short years, these new stents have become one of the best selling devices in medical history. In 2005, about 1.5 million patients were implanted with drug-eluting stents in the US alone, with the market dominated by the Taxus stent from Boston Scientific, and the Cypher from Cordis, a Johnson & Johnson company. Cypher received FDA approval in 2003, and Taxus was approved a year later.

Pepcid May Benefit Heart Failure Patients – Same Chemical Released in Stomach Causes Heart Damage

Preliminary reports from Japan indicate that the heartburn medicine, Pepcid, may help prevent or treat heart failure. The same chemical reaction that allows stomach acid to cause heartburn and create ulcers also appears to damage and weaken diseased hearts.

By blocking the chemical reaction, Pepcid also slows the progression of chronic heart failure (CHF). Masafumi Kitakaze, MD, PhD, said “We performed the present prospective study with only 50 CHF patients. Now we need to conduct a large-scale trial to confirm the present findings.” Kitakaze is director of the Cardiovascular Division and vice president of the Research and Clinical Center at the National Cardiovascular Center.

It Is Harder To Quit Smoking Menthol Cigarettes – African Americans Less Likely to Smoke non-Menthol Cigarettes

It is harder to quit smoking menthol cigarettes than non-menthol cigarettes, according to a study published in the September 25th issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Both are equally dangerous, according to the report, but menthol smokers may either by less likely to attempt or succeed at quitting.

The study says that African Americans are more likely to smoke menthol cigarettes. The researchers point out that they also suffer disproportionately higher rates of cancer, cardiovascular disease and other smoking-related illnesses. In fact, they found that African smokers are more likely to smoke menthol cigarettes than European Americans (70 percent compared to 30 percent).

Stem Cells Used To Heal Heart Show Mixed Results – Two Studies Showed Improvement in Attack Patients

Three studies using stem cells to treat damaged hearts have shown mixed results. Scientists are still looking for the right stem cells to achieve the optimum results and some say that this demonstrates the need to lift political limits on using cells from embryos. Embryonic stem cells may yield more promising results.

Rush University Medical Center cardiologist, Dr. Gary Schaer said "A person who has had a single, severe heart attack may survive but can be left with substantial damage to the heart muscle as a result of the blood supply to the heart muscle being cut off during the heart attack. The damaged muscle inhibits the heart's overall ability to pump blood, leading to heart failure."
