Additional Information: Warning Signs, Risk Factors, and Emergency Response
Sudden death can occur at any age, although the risk is generally higher among people with existing cardiovascular diseases, older adults, and individuals with certain inherited medical conditions. However, it is important to understand that sudden death does not always occur without warning. In some cases, the body may show symptoms hours, days, or even weeks before a life-threatening event.
1. Recognizing early warning signs
One of the most important steps in preventing sudden death is recognizing unusual symptoms. Chest discomfort, unexplained shortness of breath, persistent fatigue, heart palpitations, and dizziness may indicate an underlying heart problem. Some people may also experience nausea, cold sweating, or pain spreading to the arms, back, neck, or jaw during a heart attack.
