A patient presents with angina pectoris due to inadequate blood supply. Which diagnosis best describes this condition?

The diagnosis that best describes a patient presenting with angina pectoris due to inadequate blood supply is coronary artery disease (CAD). CAD occurs when the blood vessels that supply oxygen-rich blood to the heart muscle become narrowed or blocked by a buildup of plaque in the walls of the arteries. This results in reduced blood flow to the heart, leading to symptoms such as chest pain or discomfort, also known as angina.

To arrive at this diagnosis, a healthcare professional will typically consider the patient's symptoms, medical history, and may perform various diagnostic tests. These tests may include an electrocardiogram (ECG) to evaluate the electrical activity of the heart, stress tests to assess heart function during physical activity, and/or cardiac catheterization to visualize the blockages in the coronary arteries. These evaluations help in confirming the presence of CAD and determining the most appropriate treatment plan. It is important for individuals experiencing symptoms of angina to seek medical attention for proper evaluation and management of their condition.
