A growing body of research demonstrates that these vessels are protective and reduce mortality in patients with blocked coronary arteries. We should find means to promote these natural bypass vessels in order to improve outcomes for patients with heart disease.

Higher Heart Attack Risk Associated With Increased Pollution Levels
Research published on bmj.com today revealed that high levels of pollution could increase the risk of having a heart attack for up to six hours after exposure, however, the risk diminishes after a six hour time frame. Researchers speculate that the heart attack would have happened regardless and was merely pulled forward by a few hours. They base their assumption on the transient nature of the increased risk known as a short-term displacement (or "harvesting") effect of pollution. Although research has proven that high pollution levels are linked to premature death from heart disease, according to the authors, the association with an increased risk of heart attack is less clear. Krishnan Bhaskaran, an epidemiologist from the London School of Hygiene and Tropical Medicine, and his team conducted a study in which they evaluated 79,288 heart attack cases from 2003 to 2006 and hourly exposure to pollution levels. By using the UK National Air Quality Archive they investigated the levels of specific pollutants in the atmosphere, including pollutant particles (PM10), carbon monoxide (CO), nitrogen dioxide (NO2), sulphur dioxide (SO2) and ozone. Bhaskaran stated that higher levels of PM10 and NO2 are well-known markers of traffic related pollution.
Seeing that there was no net increase in heart attack risk over a broader timescale, the authors argue that there may be: "limited potential for reducing the overall burden of myocardial infarction through reductions in pollution alone, but that should not undermine calls for action on air pollution, which has well established associations with broader health outcomes including overall, respiratory and cardiovascular mortality."
Professor Richard Edwards and Dr Simon Hales from the University of Otago in New Zealand say in an accompanying editorial that: "despite the strengths of the study, it is possible that a true effect was missed because of imprecise measurements and inadequate statistical power. Given other evidence that exposure to air pollution increases overall mortality and morbidity, the case for stringent controls on pollutant levels remains strong."

Fish protected against stroke
The results of the meta-analysis shows that at least three servings of fish per week was 6 percent lower relative risk of stroke than those who ate fish less often. The researchers used data from 15 prospective studies with 9360 stroke cases among a total of over 380 000 people. They also looked at nine studies with results for different types of stroke, and found that the relative risk of stroke as well as a blood clot in the brain was 10 percent lower in those who ate three servings of fish per week. The researchers' conclusion is that there is a weak correlation between fish consumption and reduced stroke risk. High fish consumption results in a lower risk of stroke. It argues Swedish researchers in an analysis of previous studies. The study is published in the journal Stroke and made by, among others, Susanna C Larsson, a researcher at the Institute of Environmental Medicine at Karolinska Institute. http://www.dagensmedicin.se/nyheter/2011/09/12/fisk-skyddade-mot-stroke/

Hammock enjoyment explained
It's not just small children who like to be rocked to sleep - even adults fall asleep faster and sleep better if rocked gently when they sleep. The conclusion drawn by researchers at the University of Geneva in Switzerland, which had 10 men taking a nap in one of their labs. Half of the men had beds that easily swayed, half received regular beds. Those who were rocking fell asleep about 30 percent faster, and was longer in the deepest sleep stage, according to the study. Scientists believe that rocking may help to synchronize signals between a part of the brain called the hypothalamus, and cortex.

Shaquille O’Neal announces retirement from the NBA: Fan reaction
After 19 exciting years in the NBA, former Los Angeles Laker and current Boston Celtic big manShaquille O'Neal(notes) has decided to hang up his sneakers. On June 1, Shaq announced his retirement via Twitter, telling his fans/followers that he wanted them to hear it directly from him first. Despite the bumpy road full of detours that Shaq has gone down since he first entered the league in 1992, he has my utmost respect for all of the historic moments and gut-wrenching games that he was a part of. Drafted with the first overall pick in the 1992 NBA Draft by the Orlando Magic, Shaq immediately became a dominant force in the paint. Standing at 7'1'' and weighing over 300 pounds, Shaq could never be taken lightly. Despite his early impact for the Magic, it was nothing compared to the shockwaves that he would end up sending through the Lakers' organization after signing with them as a free agent in 1996.
