Cardiovascular research scientist Dr. James DiNicolantonio has shared three often-missed early warning signs of heart disease, stressing that these subtle symptoms can appear years before a major cardiac event.
Dr. DiNicolantonio, the Chief Nutrition Officer at im8health, highlighted these signs in a recent Instagram post, urging people to recognize them for early intervention.
The 3 Early Warning Signs
| Sign | Description and Warning |
| 1. Erectile Dysfunction (ED) | About half of people with heart disease experience ED, and it can precede the heart condition by up to five years. It’s caused by reduced blood flow and plaque buildup in the penile arteries, acting as an early indicator of wider cardiovascular system issues. |
| 2. Shortness of Breath During Mild Activity | Feeling unusually winded while performing light activities like climbing stairs or light exercise. If accompanied by chest discomfort or angina, it signals the heart may be struggling due to reduced efficiency or early-stage coronary artery disease. |
| 3. Swelling in Feet and Ankles | Persistent swelling or fluid retention in the lower legs, feet, or ankles. This can be a sign of heart failure or kidney dysfunction and is a commonly overlooked symptom of cardiovascular trouble. |
Dr. DiNicolantonio stresses that recognizing these symptoms early is critical for preventing severe cardiovascular events. If you notice any of these signs, prompt consultation with a doctor is necessary for early intervention, lifestyle modifications, and medical guidance.
