Parameter adds predictive information regarding CVS risk stratification | AIIMS Entrance MCQ

Which parameter adds predictive information regarding CVS risk stratification & measurement of serum cholesterol?
A. Anti-chlamydia pneumoniae antibodies 
B. CRP 
C. Homocysteine
D. Plasminogen activator inhibitor 1

Ans. B. C-reactive protein
Recent studies have demonstrated that markers of inflammation correlate with coronary risk and that inflammation plays a role in atheromatous plaque instability. 
Elevations of C-reactive protein, CRP identify patients at increased risk of myocardial infarction MI and poor outcome of acute coronary syndromes. Measurement of CRP adds information regarding risk stratification to standard risk factor such as hypertension, diabetes, smoking, and lipids.
Elevations in homocysteine, lipoprotein A, and plasminogen activator factor I have all been associated with an increased risk at cardiovascular events; however, at thi~ time none have been shown to be useful in populations to improve risk stratification.
Recent studies have suggested that infection with agents such as pneumoniae and cytomegalovirus may playa role in the development of atherosclerosis.

To date no studies have demonstrated a conclusive association, and early studies looking at the utility of antibiotic treatment in coronary artery disease have shown no benefit.
