Background: Cardiac magnetic resonance (CMR) has emerged as a reference tool for the non-invasive diagnosis of myocarditis. However, its role in follow-up (FU) after the acute event is unclear. The objectives were to assess the evolution of CMR parameters between the acute phase of infarct-like myocarditis and 12 months thereafter and to identify the predictive factors of persistent myocardial scarring at one year. Methods: All patients with infarct-like acute myocarditis confirmed by CMR were included. CMR was performed within 8 days following symptom onset, at 3 months and at one year. One-year FU included ECG, a cardiac stress test, Holter recording, biological assessments, medical history and a quality-of-life questionnaire. Patients were classified according to the presence or absence of complete recovery at one year based on the CMR evaluation. Results: A total of 174 patients were included, and 147 patients had three CMR. At one year, 79 patients (54%) exhibited persistent myocardial scarring on CMR. A multivariate analysis showed that high peak troponin at the acute phase (OR: 3.0—95%CI: 1.16–7.96—p = 0.024) and the initial extent of late gadolinium enhancement (LGE) (OR: 1.1—95%CI: 1.03–1.19—p = 0.006) were independent predictors of persistent myocardial scarring. Moreover, patients with myocardial scarring on the FU CMR were more likely to have premature ventricular contractions during the cardiac stress test (25% versus 9%, p = 0.008). Conclusion: Less than 50% of patients with infarct-like acute myocarditis showed complete recovery at one year. Although major adverse cardiac events were rare, ventricular dysrhythmias at one year were more frequent in patients with persistent myocardial scarring.

Background: Class IC antiarrhythmic drugs (AAD) are a standard treatment of cardiac arrhythmias but are associated with harm in patients with prior myocardial infarction (MI)). Consensus guidelines have advocated that these drugs not be used in patients with coronary artery disease (CAD). However, the risk of Class IC AAD in patients with stable CAD, as demonstrated by an elevated coronary artery calcium (CAC) , but a low-risk cardiac stress test (LRCST), remains unclear. We hypothesized that the risk of future adverse cardiovascular events would not differ according to CAC severity among patients with an LRCST on Class Ic AAD treatment. Methods: We identified 355 patients without CAD and an LRCST (<5% ischemia) on cardiac stress PET before initiation of Class IC AAD. CAC was assessed using quantitative scores when available or qualitative CAC assessment on low-dose attenuation correction CT. Patients were divided into no/low CAC (i.e., quantitative score <100 or qualitative assessment of none/mild) or mod/severe CAC (i.e., quantitative score ≥100 or qualitative assessment of moderate/severe) The composite primary endpoint for this analysis was ventricular tachycardia/fibrillation (VT/VF), cardiac arrest, and all-cause death at one-year follow-up. Results: The majority of patients had no/low CAC (n = 278 [78.3%]) compared to mod/severe CAC (n = 77 [21.7%]). Those with no/low CAC were younger (62 vs 70, p<0.0001) and were more likely to have a higher BMI (33.1 v 30.4, p=0.007) when compared to the mod/severe CAC group. Other cardiovascular risk factors were similar between groups. There was no difference in the one-year primary composite outcome of VT/VF, cardiac arrest, and death between no/low CAC compared to mod/severe CAC (3.6% vs 5.2%, p=0.51). Conclusion: In patients receiving Class IC AAD therapy with an LRCST, an elevated CAC did not increase the risk of future adverse events. These data suggest that using Class IC AAD may be safe in patients with stable CAD (no ischemia/elevated CAC). Future prospective trials are needed to evaluate the safety of Class IC AAD in patients with elevated CAC.

Background. Preoperative anesthetic evaluations of patients before surgery traditionally involves assessment of a patient’s functional capacity to estimate perioperative risk of cardiovascular complications and need for further workup. This is typically done by inquiring about the patient’s physical activity, with the goal of providing an estimate of the metabolic equivalents (METs) that the patient can perform without signs of myocardial ischemia or cardiac failure. We sought to compare estimates of patients’ METs between preoperative assessment by medical history with quantified assessment of METs via the exercise cardiac stress test. Methods. A single-center retrospective chart review from 12/1/2005 to 5/31/2015 was performed on 492 patients who had preoperative evaluations with a cardiac stress test ordered by a perioperative anesthesiologist. Of those, a total of 170 charts were identified as having a preoperative evaluation note and an exercise cardiac stress test. The METs of the patient estimated by history and the METs quantified by the exercise cardiac stress test were compared using a Bland–Altman plot and Cohen’s kappa. Results. Exercise cardiac stress test quantified METs were on average 3.3 METS higher than the METs estimated by the preoperative evaluation history. Only 9% of patients had lower METs quantified by the cardiac stress test than by history. Conclusions. The METs of a patient estimated by preoperative history often underestimates the METs measured by exercise stress testing. This demonstrates that the preoperative assessments of patients’ METs are often conservative which errs on the side of patient safety as it lowers the threshold for deciding to order further cardiac stress testing for screening for ischemia or cardiac failure.

Cardiac Stress Test

Cardiovascular disease is the leading cause of death worldwide. Many cardiovascular diseases are better diagnosed during a cardiac stress test. Current approaches include either exercise or pharmacological stress echocardiography and pharmacological stress magnetic resonance imaging (MRI). MRI is the most accurate noninvasive method of assessing cardiac function. Currently there are very few exercise devices that allow collection of cardiovascular MRI data during exercise. We developed a low-cost exercise device that utilizes adjustable weight resistance and is compatible with magnetic resonance (MR) imaging. It is equipped with electronics that measure power output. Our device allows subjects to exercise with a leg-stepping motion while their torso is in the MR imager. The device is easy to mount on the MRI table and can be adjusted for different body sizes. Pilot tests were conducted with 5 healthy subjects (3 male and 2 female, 29.2 ± 3.9 yr old) showing significant exercise-induced changes in heart rate (+42%), cardiac output (+40%) and mean pulmonary artery (PA) flow (+%49) post exercise. These data demonstrate that our MR compatible stepper exercise device successfully generated a hemodynamically stressed state while allowing for high quality imaging. The adjustable weight resistance allows exercise stress testing of subjects with variable exercise capacities. This low-cost device has the potential to be used in a variety of pathologies that require a cardiac stress test for diagnosis and assessment of disease progression.
