Is Knee Pain a Sign of a Heart Attack?

While knee pain is a common concern, it is generally not a direct symptom of a heart attack. This article clarifies typical heart attack symptoms and common causes of knee pain.

Understanding Heart Attack Symptoms

Heart attacks occur when blood flow to a part of the heart muscle is blocked, often due to plaque buildup in the arteries. The most recognized symptom is chest pain, which can feel like pressure, tightness, squeezing, or aching across the chest. This discomfort may last for more than 15 minutes, or it can come and go.

Pain can also spread to other areas of the upper body, including one or both arms (commonly the left), the jaw, neck, back, teeth, or even the upper belly. Other accompanying symptoms include shortness of breath, a cold sweat, nausea or vomiting, lightheadedness or sudden dizziness, and an overwhelming feeling of anxiety. Heart attack symptoms can vary significantly between individuals and may be more subtle in women, sometimes presenting as unusual fatigue, sleep problems, or pain in the back, neck, or jaw without prominent chest pain.

Common Causes of Knee Pain

Knee pain is a widespread complaint that can stem from various sources, typically unrelated to heart health. One frequent cause is osteoarthritis, a “wear-and-tear” condition where the cartilage cushioning the knee joint gradually deteriorates, leading to pain, stiffness, and sometimes a grating sensation. The pain often worsens with activity and can be felt around the entire knee.

Other common knee issues include:

  • Tendinitis: Inflammation of knee tendons, often from repetitive activities.
  • Sprains and strains: Result from overstretching or tearing ligaments or muscles/tendons due to sudden twists or impacts.
  • Bursitis: Inflammation of the fluid-filled sacs (bursae) cushioning the knee joint, causing warmth, tenderness, and swelling, particularly over the kneecap.
  • Meniscal tears: Involve the C-shaped cartilage that acts as a shock absorber, causing pain, swelling, stiffness, or a feeling of the knee locking or giving way.

When to Seek Medical Attention

For knee pain, it is advisable to seek medical attention if the pain is persistent, severe, or affects your daily activities or ability to bear weight. Swelling, warmth, redness, or a significant change in the knee’s appearance, such as deformity or inability to move it, also warrant a medical evaluation. If you experienced a “popping” sound at the time of injury or if your knee feels unstable and prone to buckling, consulting a healthcare professional is important.

In contrast, any symptoms suggestive of a heart attack require immediate emergency medical care. If you or someone around you experiences chest pain, especially if it spreads to other areas like the arm, jaw, or back, or is accompanied by shortness of breath, cold sweat, or nausea, call emergency services (like 911) right away. Prompt action is crucial in a heart attack, as emergency medical personnel can begin treatment en route to the hospital, which can significantly improve outcomes.
