(LOS ANGELES) – Every year, about 805,000 Americans have a heart attack and of these about 1 in 5 is a silent heart attack where the person is not even aware of it. During a heart attack, there is a period in which the heart is without a sufficient supply of oxygen. As a result, there may be damage to some cardiac tissues. Following the event, there may be enough damage in the heart to show long-term symptoms as chest pains, arrhythmia and a weakened ability of the heart to pump blood. In severe cases, there may be significant blood pressure changes or the heart can fail completely.
