Background Although stress-echo (SE), nuclear myocardial stress perfusion imaging (MPI) and coronary arteriography are used to detect atherosclerosis, they are not well suited for diagnosing inflammatory heart disease. Cardiac MRI (CMR) is uniquely capable of detecting myocardial and pericardial edema, a hallmark of inflammation. As the myocardium and pericardium are contiguous, myocarditis and pericarditis often coexist. This study assessed the prevalence of myocarditis and pericarditis in patients with chest pain and a negative ischemic evaluation, using CMR. Methods An institutional cardiac imaging database was queried for patients with chest pain who underwent CMR after a normal ischemic evaluation. CMR criteria for inflammation included myocardial/pericardial enhancement on T2 STIR, early gadolinium enhancement, increased T1 mapping relaxation time, increased T2 mapping relaxation time, and delayed gadolinium enhancement. At least 2 of these findings were required for a diagnosis of myocarditis or pericarditis. The prevalence of myocarditis/pericarditis was computed for patients with a negative SE, MPI or CMR stress study separately. Results There were 1,476 patients with chest pain and negative ischemic evaluation. Of 149 patients with a normal SE, 10 (6.8%) had evidence of myocarditis. Of these 10 patients, nine (90%) were female. These same 10 patients (100%) also had coexisting pericarditis (10% male, 90% female). Of 403 patients with a normal MPI, 29 (7.2%) had myocarditis. 22 of these 29 (75.9%) also had CMR findings of pericarditis. Of 924 patients with a normal CMR stress perfusion study, 63 (6.8%) had myocarditis on CMR. Of these 63 patients, 48 (76.2%) had CMR evidence of pericarditis as well. Conclusion This study suggests a 7% prevalence of underlying myocarditis in patients presenting with chest pain and a negative ischemic evaluation. Additionally, 78% of these patients had evidence of coexisting pericarditis. Females with normal stress-echo results are more likely to have a missed diagnoses of acute myocarditis and pericarditis. These data emphasize the value of CMR for diagnosing underlying myocarditis and pericarditis, after a negative ischemic evaluation.
