What type of test is commonly performed to confirm or rule out potential heart disease?

A coronary angiogram is a highly specialized imaging technique used to visualize the inside of coronary arteries. This test is commonly performed to confirm or rule out potential heart disease, particularly in patients who exhibit symptoms such as chest pain, shortness of breath, or other risk factors for coronary artery disease. During the procedure, a contrast dye is injected into the coronary arteries through a catheter, allowing for the assessment of blood flow and identifying any blockages or abnormalities in the arteries. This makes it a critical tool in diagnosing heart conditions and determining the best course of treatment.

The other tests listed are not specifically intended to assess heart disease. Thyroid function tests evaluate thyroid hormone levels and their effects on metabolism but do not provide direct information about heart health. A fasting blood sugar test is primarily used to assess glucose levels and is more relevant to identifying diabetes rather than heart disease. A complete blood count measures various components of blood, like red and white blood cells, but does not specifically diagnose cardiac issues.
