Key Warning Signs of Cardiac Arrest and Other Health Indicators

Health experts highlight several early signs that may indicate serious underlying conditions. Thin hair before age 40, especially when affecting more than half of the scalp in people under 30, can be a warning of diabetes. A red tint in the white of the eyes may signal hypertension, while a yellow tint can point to jaundice or liver problems. Swelling in the front of the neck should prompt evaluation for thyroid disorders, which are common among women aged 20‑50. Cold feet, being the most distant part of the circulatory system, are often linked to cardiovascular disease.

A report from the American Heart Association, published in the journal *Circulation*, outlines subtle symptoms that may precede cardiac arrest, such as shortness of breath, unexplained fatigue, neck swelling, cold feet, and occasional abdominal discomfort. Additional early signs include dizziness, nausea, loss of appetite, and mood disturbances like depression or anxiety. While cardiac arrest is usually fatal, prompt medical attention, lifestyle changes, and appropriate medication can improve survival and quality of life. Risk factors include smoking, excessive alcohol consumption, physical inactivity, poor diet, high blood pressure, obesity, and diabetes.
