Heart disease is the No. 1 killer of men and women in America today. The American Heart Association defines ideal cardiovascular health based on seven health factors: smoking status, weight, physical activity, healthy diet, cholesterol, blood pressure and fasting glucose levels, as well as the absence of a diagnosis of heart or blood vessel disease.Based on that definition, new data shows 94 percent of U.S. adults have at least one and 38 percent have at least three of the seven factors at “poor” levels.That’s why River Park Hospital is holding its 2012 Heart Healthy Fair this Saturday, Feb. 25.
