...doctors talk about a "golden hour" after someone suffers a heart attack or stroke, during which prompt medical attention can lead to complete or nearly complete recovery. But when it comes to cardiac arrest, in which the heart's electrical signals become so disorganized that it can no longer pump blood, that precious window is reduced to just a minute or two. For each minute that the heart is not shocked, or defibrillated, back to normal, a person's chance of survival drops 10%. After 10 minutes, the chances of survival--not to mention recovery--shrink to nearly zero...
...there are cases in which homocysteine levels may prove vitally important. People with kidney disease or diabetes, for example, or those who have a family history of heart disease are much more likely to suffer a heart attack. For them, even a modest decrease in cardiac risk can pay big dividends. Moreover, some people have a genetic mutation that reduces levels of a homocysteine-eating enzyme. A second meta-analysis, out of the Netherlands and also reported in last week's JAMA, shows that the mutation raises heart-disease rates 16%--and thus makes the impact of homocysteine reduction correspondingly...
...itself. Anew study of 40,000 men finds that while "moderate" is good, "intense" is better. Men who ran an hour or more weekly were 42% less likely to develop heart disease--more than twice the benefit of walking 30 min. a day. Men who lifted weights cut their cardiac risk 23%. It may be best to pick up the pace and pump iron, but doing anything is always better than doing nothing. --By David Bjerklie...
