Overview
Invasive Coronary AngiographyInvasive coronary angiography (ICA) defines the pres-ence and severity of a luminal obstruction of an epicar-dial coronary artery, including its location, length, and diameter, as well as coronary blood flow.1,2 For ICA, the primary goal is the characterization and detection of a high-grade obstructive stenosis to define feasibility and necessity of percutaneous or surgical revascularization. The use of physiologic indices (IFR and FFR) provides complementary functional information.1 Radiation expo-sure to the patient during an interventional procedure averages 4 to 10 mSv and is dependent on procedural duration and complexity.3,4ICA has a spatial resolution of 0.3 mm; as such, it is impossible to visualize arterioles (diameter of 0.1 mm) that regulate myocardial blood flow.5 Coronary vascular functional studies can be performed during coronary angiography. Normal angiography does not exclude abnormal coronary vascular function, and it is possible to assess coronary microcirculation and coronary vaso-motion. Coronary function testing may assist in
Other Diagnostic Studies
- Patients who are suspected to have coronary artery disease may require stress testing or angiography to visualize their coronary arteries.
- Peak flow studies and pulmonary function tests may be indicated for patients requiring further evaluation of lung function.
