The final stage of a heart attack occurs when the heart muscle is significantly damaged, and the heart cannot function properly. This can result in a full-blown heart attack, which is a medical emergency that requires immediate attention. Symptoms of a heart attack can include chest pain or discomfort, shortness of breath, dizziness, sweating, and nausea. If you or someone you know is experiencing these symptoms, it is important to seek medical attention right away.To get more info on this product, visit Outlook Health.
