Your body may be trying to warn you of an impending cardiac episode. Researchers have found that cardiac arrest is not as much of a surprise as people may think. In fact, there may be symptoms you should be paying attention to. “A recent study that analyzed 839 sudden cardiac arrests found that in 430 cases, or 51 percent, patients exhibited warning signs in the four weeks before the arrest. The victims either failed to recognize the symptoms or ignored them—in most cases until it was too late. The missed symptoms included chest pain, shortness of breath, lightheadedness and heart palpitations—classic signs of an impending or actual heart attack.” It is important to see a doctor if you start to have any of these symptoms in order to prevent a dangerous attack or potential death.
