In the study, the researchers found that African American center failure sufferers with the genetic variation acquired an all natural protection against loss of life and the necessity for a heart transplant that is the same as the protection supplied by beta-blocker therapy. The experts say their discovery increases the accumulating evidence that genetic differences donate to the way people react to medications, and really should encourage the use of genetic tests in clinical trials to recognize people who can benefit from therapy tailored with their personal genetic make-up.
