CRP and infection: Other inflammatory markers, such as lactate, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and procalcitonin, are elevated in myocarditis, but these markers were not followed as they are often raised in the presence of infection [7]. ECG changes were found to be vague but included sinus tachycardia and nonspecific ST-segment and T-wave abnormalities, and may be used in conjunction with other studies [9].
