According to researchers is stretched heart muscle and scar tissue, known as ventricular dilation, a common consequence of heart attack. The heart dilates, or thins out, in response to increasing pressure within the heart, forcing it to work harder and less efficiently to pump blood through the body. Heart valve leaks commonly result, the demand also, surgical repair.
The most recent estimates by the American Heart Association in 2004 showed that over 5 million Americans currently suffer from heart failure, hree-quarters of high blood pressure ahead. All have a higher risk of obesity and heart attack.‘the general rule, more complex organisms, as people, have bigger genomes of than less complex, ‘said J. Todd Streelman, assistant editor professor at School of Biology at Georgia Institute of Technology and co-author the study. ‘might think means this mean that the Pets with the greatest genomes of the tasks are com. And mostly the right thing But there is are not always true There some of species of frogs and some of amoebae which has much greater genomes than man. ‘.
They also found that types did of smaller effective population size major genomes.
We see a very serious adverse linear relationship between genome of size and the effective population size , Soojin Yi, said Assistant Professor of into the Faculty of Biology and lead author of degree. This observation indicates that the mutations that tilt to raise genome slightly damaging, because population genetic theories predict such a relationship. – The interesting thing is has of biological complex may developing pasive, said Yi. We will show that the origin, is do not adaptive mutations but somewhat poor of making the the genome larger.
