The Early Signs and Symptoms of Coronary Artery Disease

Coronary artery disease (CAD), also known as coronary atherosclerotic heart disease, occurs when the arteries that supply blood to the heart muscle become narrowed due to the buildup of plaque. This process, known as atherosclerosis, restricts blood flow and can lead to inadequate oxygen supply to the heart, causing a range of symptoms.

Typical Early Symptoms of CAD

One of the most common early indicators of coronary artery disease is chest pain, medically referred to as angina. This discomfort often occurs during physical exertion, such as climbing stairs or exercising, because the heart requires more oxygen-rich blood during these times. In the early stages of CAD, the body may still manage blood flow adequately at rest, but during activity, the narrowed arteries can't supply enough blood to meet the heart's increased demands. As a result, individuals may experience pressure, tightness, or pain in the chest.

Atypical Symptoms to Watch For

In addition to the classic signs, there are several atypical symptoms associated with coronary artery disease. These may include shortness of breath, fatigue, and a general feeling of unease. Some people experience pain or discomfort that radiates to the left shoulder, arm, or even up to the jaw. Others may feel a choking sensation in the throat or unexplained tooth pain, which can be misleading and cause individuals to overlook the cardiac origin of these symptoms.

Why Early Detection Matters

Recognizing these early signs is crucial for timely diagnosis and treatment. Many people dismiss these symptoms as unrelated or stress-related, which can delay necessary medical intervention. If you experience any of these symptoms regularly, especially during physical activity, it's important to consult with a healthcare professional to assess your heart health and determine if further testing is needed.
