Which test assesses the risk of coronary artery disease (CAD)?

• A. Lipid profile
• B. Cardiac C-reactive protein
• C. Troponin
• D. BNP

Answer: (B)

The assessment of risk for coronary artery disease (CAD) is effectively evaluated through the measurement of cardiac C-reactive protein (CRP). This test measures inflammation in the body, and elevated levels of CRP have been associated with an increased risk of cardiovascular conditions, including CAD. This connection stems from the understanding that chronic inflammation plays a significant role in atherogenesis—the formation of plaque in the arteries—which can lead to heart disease and related complications.

While other tests listed, such as the lipid profile, are common in evaluating lipid levels and potential risk factors for CAD, they do not specifically address the inflammatory aspect as prominently as CRP. Troponin is primarily used to detect myocardial injury and cannot be used to assess chronic risk for CAD. Similarly, BNP (B-type Natriuretic Peptide) is utilized mainly for diagnosing and managing heart failure rather than directly assessing the risk for coronary artery disease. Thus, the focus on inflammation provided by the cardiac CRP test makes it a valuable tool in understanding and predicting the risk of CAD.
