Treatment and Management Interpretation
Though modern medicine offers women a powerful arsenal of proven life-saving treatments after a heart attack, from aspirin to surgery, a persistent gap in timely care, appropriate application, and consistent follow-through means we are too often arming them for a battle they must then fight with one hand tied behind their back.
