Cardiac catheterization may be used to verify and support data from which type of testing?

• A. Verify and support non-invasive data
• B. Prepare for surgery
• C. Measure lipid levels
• D. Treat infection

Answer: (A)

Cardiac catheterization is used to verify and support data from noninvasive testing by giving direct, quantitative information that imaging and stress tests can only suggest. Through coronary angiography, it directly visualize coronary arteries to confirm the presence and severity of blockages that noninvasive tests hint at. It also measures intracardiac pressures, valve gradients, and cardiac output, validating valvular disease, shunts, or ischemia indicated by echocardiography or other noninvasive studies. This direct view and precise hemodynamic data provide a definitive assessment that helps guide treatment decisions, such as pursuing revascularization or valve intervention. Lipid levels are assessed with blood tests, infections are diagnosed by clinical signs and labs, and prep for surgery involves broader evaluation beyond what cath alone confirms, so those options don’t fit the primary role here.
