According to the U.S. Centers for Disease Control and Prevention, 6.7 million Americans aged 20 and older are living with heart failure, a condition in which the heart cannot pump enough blood to meet the body's needs. After being diagnosed with heart failure, 52.6% of patients die within five years. The leading cause of heart failure is a heart attack, which affects over 800,000 Americans annually. During a heart attack, the heart muscle often becomes damaged due to a lack of oxygen and increased oxidative stress. This damage can result in inflammation and scarring, which ultimately weaken the heart, leading to heart failure. While current treatments can restore blood flow, they do not entirely prevent the long-term damage that causes heart failure over time. Now, scientists have developed a new, potent injectable therapy that can protect the heart from damage following a heart attack.
