perfusion stress test

A perfusion stress test is a diagnostic procedure that evaluates blood flow to your heart muscle during exercise or medication-induced stress. It helps identify areas with reduced blood supply caused by narrowed or blocked coronary arteries. The test typically involves injecting a special dye and taking imaging scans while you are stressed, either through physical activity or drugs that simulate exercise. This allows doctors to assess how well blood is reaching your heart tissue, guiding diagnosis and treatment for conditions like coronary artery disease.
