Abstract Aims Myocarditis due to COVID-19 mRNA vaccine is an uncommon side effect and the cases seem to have occurred predominantly in young adults under 30 years old. The estimated incidence is 12.6 cases per one million second dose m-RNA vaccine delivery. Methods and results A 17-years-old male was admitted at our department after 18 days COVID-19 Pfizer-BioNtech vaccine second dose delivery with persistent chest pain without respiratory symptoms and, ST-elevation and PR-depression in V3–V6 at the ECG on 3 August 2021. He had no history of heart disease. Physical examination didn’t show anything relevant except for mildly tachycardic heart sounds. In addition blood test showed increase in C-reactive protein, cardiac troponin and N-terminal-pro-B-type natriuretic peptide. An echocardiography showed widespread hypokinesia with reduced left ventricular ejection fraction and highly echogenic pericardium. During the first day cardiac magnetic resonance (CMR) was performed, which showed mild diffuse myocardial oedema on T2-weighted images and T2 mapping and two thin areas of delayed enhancement with non-ischaemic pattern in the lateral wall with involvement of the pericardial sheets confirming peri-myocarditis diagnosis. After 24 h, the ECG showed spread and deep T-waves with QTc prolongation. We performed multiple ECG during the days after to assess morphology changes and QTc. The patient has been asymptomatic for all the hospitalization and on day 7 was performed an echocardiography which describe a full recovery in terms of kinesia and left ventricular ejection fraction. He was discharged asymptomatic with ‘better’ but still negative T-waves and QTc normalization. Two months after discharge CMR was repeated and showed normal left ventricular function without myocardial oedema and pericardial involvement, but with persistent the areas of delayed enhancement with non-ischaemic pattern in the lateral wall. Conclusions In this case report we describe an uncommon COVID-19 m-RNA Vaccine side effect. The first issue is the timing of presentation. On 19 July 2021, AIFA stated that myocarditis is a very uncommon side effect and it usually presents within 14 days after 2nd dose delivery. Our patient was admitted at our department after that time period, probably because we reported the ending part of the myocarditis presented with symptoms of pericarditis; indeed we didn’t report the cardiac troponin plateau but only the descending cardiac troponin wave and we attend a very quick recovery. The second issue in the unique ECG with a very quick evolution (Tako-Tsubo morphology like) which could be characteristic of this kind of Myocarditis. Third, the good progress of the inflammation and quick recovery. Surely is a serious side effect but it’s still less frequent and with better prognosis than COVID-19 Myocarditis. European Medicines Agency (EMA) and Centers for Disease Control and Prevention (CDC) recently stated authorized COVID-19 vaccines advantages are still above risks in all age groups beyond 12 y/o. Why is myocarditis a side effect, Why are adolescent males affected the most and Why is the onset after second dose of m-RNA vaccine are questions still unanswered.

Hypertensive Disorders

Background: Cardiovascular functions and hemodynamics dramatically change during pregnancy such as cardiac output, expanded blood volume, reduced systematic vascular resistance, and heart chamber enlargement. Hypertensive disorders of pregnancy (HDP) may affect the cardiac load during pregnancy; however, the data about plasma concentration of cardiac troponin in pregnant women with HDP is very limited. Methods: We prospectively collected data of 751 pregnant women between 2012 and 2013 in Japanese general hospital. We analyzed laboratory data and echocardiographic findings after delivery. The elevated cTnI was defined as >0.015 ng/mL because the normal population have serum cTnI of less than 0.015 ng/mL in this assay. Results: The HDP were observed in 32 patients; the elevated cTnI was observed 40 patients. The age of patients with HDP (33.7 ±4.3 years) was not different from that of those without HDP (33.3 ± 5.0 years). The brain natriuretic peptides levels were not different between those with and without HDP. The proportion of elevated cTnI was higher in those with HDP (21.8%) than those without (3.6%, P<0.0001). After adjusting for confounders, the risk of elevated cTnI in those with HDP relative to those without HDP remained significant (odds ratio 4.52, 95% confidence interval 1.45-14.5). There were no women with reduced left ventricular ejection fraction. Conclusions: HDP was associated with elevated cTni, suggesting myocardial microinjury might occur more frequently in those with HDP.

Background: In the diagnosis of acute coronary syndrome, cardiac troponin I is highly reliable and widely available biomarker. Serum level of cardiac troponin I is related to amount of myocardial damage and also closely relates to infarct size. Our aim of the study is to find out the relationship between cardiac troponin I and left ventricular systolic function after acute coronary syndrome. Methods: Total of 132 acute coronary syndrome patients were included in this study after admission in coronary care unit of Sir Salimullah Medical College, Mitford Hospital. Troponin I level was measured at admission and left ventricular ejection fraction (LVEF) was measured by echocardiography between 12-48 hours of onset of chest pain. Results: There was negative correlation between Troponin I at 12 to 48 hours of chest pain with LVEF in these study patients. With a cutoff value of troponin I e”6.8 ng/ml in STEMI patients there is a significant negative relation between 12 to 48 hrs troponin I and LVEF (p<0.001). Sensitivity of troponin I e” 6.8 ng/ml between 12 to 48 hours of chest pain in predicting LVEF <50% in STEMI was 93.75% and specificity was 77.78%. In NSTEMI sensitivity of troponin I e” 4.5 ng/ml between 12 to 48 hours of chest pain in predicting LVEF <50% was 65% and specificity was 54.05%. Conclusion: Serum troponin I level had a strong negative correlation with left ventricular ejection fraction after acute coronary syndrome and hence can be used to predict the LVEF in this setting.

Background. Acute myocardial oedema has been documented in experimental models of ischemia-reperfusion injury or sepsis and is usually investigated by magnetic resonance imaging.Purpose. We describe a case of acute ventricular wall thickening documented by echocardiography in a patient developing sepsis and thrombotic microangiopathy.Case Description. A 40-year-old woman, with a history of mixed connective tissue disease, was admitted with laryngeal oedema and fever. She developedStreptococcus pneumoniaesepticaemia and subsequent laboratory abnormalities were consistent with a thrombotic microangiopathy. Echocardiography revealed an impressive diffuse thickening of the whole myocardium (interventricular septum 18 mm; posterior wall 16 mm) with diffuse hypokinesia and markedly reduced left ventricular ejection fraction (31%). There was also a moderate pericardial effusion. Echocardiography was normal two months before. The patient died from acute heart failure. Macroscopic and microscopic examination of the heart suggested that the ventricular wall thickening was induced by oedematous changes, together with an excess of inflammatory cells.Conclusion. Acute ventricular wall thickening that corresponded to myocardial oedema as a first hypothesis was observed at echocardiography during the course of septicaemia complicated by thrombotic microangiopathy.

The nature and kinetics of postexercise cardiac troponin (cTn) appearance is poorly described and understood in most athlete populations. We compared the kinetics of high-sensitivity cTn T (hs-cTnT) after endurance running in training-matched adolescents and adults. Thirteen male adolescent (mean age: 14.1 ± 1.1 yr) and 13 male adult (24.0 ± 3.6 yr) runners performed a 90-min constant-load treadmill run at 95% of ventilatory threshold. Serum hs-cTnT levels were assessed preexercise, immediately postexercise, and at 1, 2, 3, 4, 5, 6, and 24 h postexercise. Serum NH2-terminal pro-brain natriuretic peptide (NT-pro-BNP) levels were recorded preexercise and 3, 6, and 24 h postexercise. Left ventricular function was assessed preexercise, immediately postexercise, and 6 h postexercise. Peak hs-cTnT occurred at 3–4 h postexercise in all subjects, but was substantially higher ( P < 0.05) in adolescents [median (range): 211.0 (11.2–794.5) ng/l] compared with adults [median (range): 19.1 (9.7–305.6) ng/l]. Peak hs-cTnT was followed by a rapid decrease in both groups, although adolescent data had not returned to baseline at 24 h. Substantial interindividual variability was noted in peak hs-cTnT, especially in the adolescents. NT-pro-BNP was significantly elevated postexercise in both adults and adolescents and remained above baseline at 24 h in both groups. In both groups, left ventricular ejection fraction and the ratio of early-to-atrial peak Doppler flow velocities were significantly decreased immediately postexercise. Peak hs-cTnT was not related to changes in ejection fraction, ratio of early-to-atrial peak Doppler flow velocities, or NT-pro-BNP. The present data suggest that postexercise hs-cTnT elevation 1) occurred in all runners, 2) peaked 3–4 h postexercise, and 3) the peak hs-cTnT concentration after prolonged exercise was higher in adolescents than adults.

Introduction/Objective. Numerous anomalies of the cardiac venous system prevent the optimal endovascular implantation of the left ventricular (LV) lead in more than 15% of patients with indication for cardiac resynchronization therapy (CRT). The endovenous approach in these patients can be one of the potential reasons for the large number of nonresponders reported in the literature. The purpose of this study was to analyze the results of an alternative myoepicardial approach to the stimulation of the left ventricle in CRT. Methods. From June 2014 to December 2015 at the Department of Cardiac Surgery of the Clinical Centre of Serbia, 15 myoepicardial LV leads for CRT were implanted. Coronary sinus venography revealed thrombosis of the coronary sinus in nine patients, and unfavorable anatomy of the coronary venous system in six patients. In all patients, limited left thoracotomy was used as an approach to the lateral wall of the heart. Results. There were no major surgical complications and no lethal hospital outcomes. In a six-month follow-up period we registered a significant increase in the length of the six-minute walk test (for an average of 57.9 m), reduction of the QRS complex width (to 26.25 ms), increase in left ventricular ejection fraction (12.2%), and reduction of mitral regurgitation for 1+. Based on all the parameters, it was concluded that all patients responded favorably to the applied CRT. Conclusion. Closer cooperation between cardiologists and cardiac surgeons in identifying patients who would benefit the most from a myoepicardial approach for LV stimulation is necessary in order to attempt to reduce the nonresponder rate.

Background: Fulminant myocarditis (FM) is a fatal disease that causes rapid-onset severe heart failure requiring inotropes or mechanical circulatory support (MCS). Because insufficient myocardial recovery requires durable left ventricular assist device or heart transplantation, the course of myocardial recovery should be predicted. Hypothesis: Cardiac troponins, which elevates due to myocardial damage, may associate with myocardial recovery in FM. Purpose: We aimed to investigate the relationship between cardiac troponin T (TnT) levels and myocardial recovery course in patients with FM. Method: We performed a retrospective medical record review of 19 patients with FM requiring MCS from May 2012 to January 2020. The serial changes of one-week left ventricular ejection fraction (LVEF) after MCS implantation according to TnT levels were evaluated. Results: Median age was 50 years and 10 patients were male. As for initial MCS, veno-arterial extracorporeal membrane oxygenation (VA-ECMO) with intra-aortic balloon pumping (IABP) were used in 13 patients, IABP in 4 patients, VA-ECMO in one patient, and impella 2.5 in one patient. Median peak TnT level within one week after MCS implantation were 4.43 (2.47 - 34.6) ng/mL. The patients were divided into High-TnT group and Low-TnT group according to median peak TnT level. All patients in both groups were alive until 7 days after MCS implantation, and LVEF on day 7 was significantly lower in the High-TnT group (Fig). TnT level was highest on day 1 and gradually decreased in the High-TnT group (Fig). Six patients died during hospitalization in the High-TnT group, in contrast, only one patient died in the Low-TnT group (p=0.020). Peak TnT level in patients with LVEF ≥30% (n=8) on day 7 was significantly lower than in patients with LVEF <30% (2.40 vs 13.5 ng/mL, p=0.012), however, other laboratory parameters showed no significant differences. Conclusion: Higher TnT level showed impaired myocardial recovery in patients with FM.

Despite pathologic evidence of myocardial inflammation, the significance of myocarditis in children with acute rheumatic carditis remains controversial. Elevations in cardiac troponin I have been demonstrated in other forms of myocarditis. The purpose of our study was to determine if levels of cardiac troponin I are elevated, suggesting myocardial injury, in patients with acute rheumatic carditis. We identified all those patients with acute rheumatic fever, presenting between July 1998 and December 2000, who had clinical evidence of carditis, such as a new murmur of mitral or aortic regurgitation, and who had an echocardiogram, measurements of levels of cardiac troponin I, erythrocyte sedimentation rate, and/or C-reactive protein performed at the time of presentation. Their charts were reviewed for demographic and clinical data. Echocardiograms were reviewed for severity of aortic and mitral regurgitation, and measurements made of left ventricular ejection fraction, fractional shortening, and end-diastolic dimension. We found 16 patients with acute rheumatic carditis, ranging in age from 2.0 to 16.1 years, with just over one-third having symptoms of congestive heart failure. All patients had evidence of acute inflammation. There was a significant relationship between symptoms and severity of mitral regurgitation. No patient had elevated levels of cardiac troponin I level. The fact that levels of cardiac troponin I are not elevated in the serum of children with acute rheumatic carditis suggests that there is minimal myocytic necrosis in this setting. This supports the concept that acute valvar regurgitation is the major hemodynamic abnormality in these patients.

Abstract BACKGROUND Quantification and comparison of high-sensitivity (hs) cardiac troponin I (cTnI) and cTnT concentrations in chronic kidney disease (CKD) have not been reported. We examined the associations between hs cTnI and cTnT, cardiovascular disease, and renal function in outpatients with stable CKD. METHODS Outpatients (n = 148; 16.9% with prior myocardial infarction or coronary revascularization) with an estimated glomerular filtration rate (eGFR) of &lt;60 mL · min−1 · (1.73 m2)−1 had serum cTnI (99th percentile of a healthy population = 9.0 ng/L), and cTnT (99th percentile = 14 ng/L) measured with hs assays. Left ventricular ejection fraction (LVEF) and mass were assessed by echocardiography, and coronary artery calcification (CAC) was determined by computed tomography. Renal function was estimated by eGFR and urine albumin/creatinine ratio (UACR). RESULTS The median (interquartile range) concentrations of cTnI and cTnT were 6.3 (3.4–14.4) ng/L and 17.0 (11.2–31.4) ng/L, respectively; 38% and 68% of patients had a cTnI and cTnT above the 99th percentile, respectively. The median CAC score was 80.8 (0.7–308.6), LV mass index was 85 (73–99) g/m2, and LVEF was 58% (57%–61%). The prevalences of prior coronary disease events, CAC score, and LV mass index were higher with increasing concentrations from both hs cardiac troponin assays (P &lt; 0.05 for all). After adjustment for demographics and risk factors, neither cardiac troponin assay was associated with CAC, but both remained associated with LV mass index as well as eGFR and UACR. CONCLUSIONS Increased hs cTnI and cTnT concentrations are common in outpatients with stable CKD and are influenced by both underlying cardiac and renal disease.
