Heart disease, especially heart attacks, is the top cause of death in the United States.
Why heart disease leads the mortality list
Every year roughly 735,000 Americans experience a heart attack, and a substantial portion of those are fatal. Cardiovascular problems outpace cancer, accidents, and other illnesses because they develop silently over decades of poor diet, inactivity, high blood pressure, and untreated cholesterol.
How to reduce the risk
Prevention focuses on simple, evidence‑based habits: eating whole foods, staying active, managing stress, and keeping regular appointments to monitor blood pressure, cholesterol, and blood sugar. Knowing these numbers early can make the difference between life and death.
What to watch for
Symptoms aren’t always dramatic. Chest discomfort, shortness of breath, fatigue, or jaw pain can signal a heart attack, even in younger adults. Prompt medical attention is critical.
