THURSDAY, May 15 (HealthDay News) -- New guidelines for implanted heart devices such as pacemakers and defibrillators emphasize that they're just one aspect of cardiac care.
In dogs with damaged hearts, implanted pacemakers triggered fast improvements in tissue levels and the activity of a number of proteins crucial to heart health, says a Johns Hopkins study.
The researchers said their findings are believed to be the first detailed chemical analysis of the biological effects a pacemaker has on the heart. This new information could lead to improvements in the use of combined pacemaker/drug treatments for congestive heart failure patients.
