Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Atherosclerosis is looked upon as an inflammatory disease. The production of proinflammatory markers may indicate activity in this inflammatory state.', 'We prospectively evaluated a range of proinflammatory serum parameters in 136 cardiac patients who had previously undergone percutaneous coronary intervention (PCI).', 'By means of myocardial scintigraphy, an ischemia group (A; n=49) and a group with stable cardiovascular disease without exercise induced ischemia (B; n=87) were distinguished. Risk factors and lipoprotein profile of both groups were comparable. Serum levels of serum C-reactive protein (CRP), IL-6, sTNF-RI, IGF-I, neopterin, serotonin and prolactin did not present any significant difference between the two groups.
Do proinflammatory parameters as CRP and IL-6 discriminate between post-PCI cardiac patients with and without exercise-induced ischemia as indicated by Tl-201 myocardial scintigraphy?
