Relation of Nocturnal Melatonin Levels to C-Reactive Protein Concentration in Patients With ST-Segment Elevation Myocardial Infarction

C-reactive protein, a marker of inflammation, is increasingly measured to stratify risk for coronary artery disease and guide clinical management. Likewise, a relation has been suggested between decreased nocturnal melatonin levels and coronary artery disease. However, little is known about the association between melatonin and C-reactive protein in patients with ischemic heart disease.
