What is CAD?
Coronary artery disease is a type of atherosclerosis that affects the arteries supplying blood to the heart. When these arteries become clogged with plaque, the heart receives less oxygen-rich blood, increasing the risk of heart attacks.
Surprisingly, CAD can also show symptoms in the feet:
- Swelling (edema): Poor heart function can lead to fluid retention, causing swelling in the feet and ankles.
- Tingling or numbness: Decreased circulation may result in pins and needles sensations in the toes.
- Skin changes: The skin on the feet may become shiny and tight due to fluid buildup and poor circulation.
- Foot pain at rest: Unlike PAD, CAD-related foot pain may persist even when resting, especially at night.
- Brittle toenails: Poor blood supply may weaken toenails, causing them to become thick and brittle.
According to the American Heart Association (AHA), “children and youth are increasingly at risk for CAD. So, preventive measures taken early in life can have greater lifetime benefits.” Healthy lifestyles – managed by good nutrition, weight management and physical activity – “will delay the progression of CAD, and there is hope that it can be improved before it causes further health problems.”
And, AHA warns that if you have PAD or CAD, chances are very high that you have the other.
