Which of the following is a symptom of coronary artery disease?

Chest pain is a classic symptom of coronary artery disease (CAD) and is specifically indicative of the condition due to the reduced blood flow to the heart muscle caused by narrowed or blocked coronary arteries. This pain, often referred to as angina, can present as a feeling of pressure, squeezing, fullness, or pain in the center or left side of the chest. It may also radiate to the shoulders, neck, arms, back, teeth, or jaw, which aligns with how CAD manifests in patients experiencing myocardial ischemia.

In contrast, rash, joint pain, and constipation are not associated with coronary artery disease. While these symptoms may indicate other medical conditions, they do not reflect the primary characteristics of CAD, thereby making chest pain the only relevant symptom in this context. Understanding the specific symptoms associated with coronary artery disease is crucial for timely diagnosis and treatment.
