Background: Variant, or reverse, Takotsubo cardiomyopathy (TTC) is defined by left ventricular basal and/or mid-ventricular systolic dysfunction with preserved apical function. This condition is increasingly recognized, yet there have been few studies comparing variant and typical TTC. This study aims to contrast the demographic features and clinical outcomes of patients with variant and typical TTC. Methods: All patients at a single academic medical center with a discharge diagnosis of Takotsubo syndrome [ICD-9-CM 429.83] from 2010-2014 were identified. Patients who met the Mayo Clinic criteria for TTC were included and were then grouped into typical or variant TTC categories based on wall motion abnormality patterns. Results: The initial query identified 275 patients with a discharge diagnosis of TTC, of which 145 (52.7%) met diagnostic criteria for TTC. Typical TTC was present in 125 patients (86.2%) and variant TTC in 20 patients (13.8%). The demographic and clinical characteristics of these groups are summarized in table 1. Variant TTC patients were more likely to be male and subject to a physically stressful trigger. Typical TTC patients had lower left ventricular ejection fraction, higher left ventricular end-diastolic pressure, and were more likely to be intubated. Cardiac biomarkers were not significantly different between groups. In-hospital mortality, length of hospital stay, TTC recurrence and follow-up LVEF were similar between groups. Conclusions: There are important differences between patients with variant and typical TTC. Variant TTC is not as strongly associated with female sex, it is more frequently preceded by a physical stressor, and it has a more benign presentation. Long term outcomes are favorable in patients with variant and typical TTC.

Background: Immune regulation and inflammation play a role in the pathogenesis and progression of acute and chronic heart failure (HF). While overt inflammatory cardiomyopathy is a well-described clinical entity marked by acute cardiac dysfunction and relatively high rates of recovery, trajectories in cardiac function among people with chronically heightened systemic inflammation are less clear. We hypothesized that there are differences in trajectories of left ventricular ejection fraction among HF patients with different chronic inflammatory diseases (CIDs): human immunodeficiency virus (HIV), systemic lupus erythematosus (SLE), systemic sclerosis (SSc), rheumatoid arthritis (RA), inflammatory bowel disease (IBD), or psoriasis. Methods: We analyzed serial echocardiographic data from people with CIDs and HF who had at least three echocardiograms (n=974) at a large academic medical center. We identified latent trajectories patterns of LVEF using latent class trajectory models, then described clinical differences across the different trajectories. We then used multinomial regression to test if CID type and other baseline variables were associated with different trajectories. Results: We observed three major LVEF trajectories which paralleled known HF subtypes: preserved/intermediate EF (HFp/iEF, 687, 70.5%), reduced EF (HFrEF, 255, 26.2%), and recovered EF (HFrecEF, 32, 3.3%). These trajectories corresponded closely to accepted clinical definitions. For example, 30/32 (94%) patients in the HFrecEF trajectory had LVEF <40% at baseline that increased ≥15% on ≥1 follow-up. We observed significant differences in associations of CID type, age, sex, and diabetes with a specific LVEF trajectory (Figure) that remained even after regression. Conclusions: Among people with HF and CIDs, different trajectories of LVEF are associated with different CIDs and clinical characteristics. This may have implications for therapy and prognosis of HF in CIDs.

Abstract Aims myocardial involvement in the course of Coronavirus disease 2019 (COVID-19) pneumonia has been reported, though not fully characterized yet. Aim of the present study is to undertake a joint evaluation of hs-Troponin and natriuretic peptides (NP) in patients hospitalized for COVID-19 pneumonia. Methods and results in this multicenter observational study, we analyzed data from n = 111 COVID-19 patients admitted to dedicated “COVID-19” medical units. Hs-Troponin was assessed in n = 103 patients and NP in n = 82 patients on admission; subgroups were identified according to values beyond reference range. increased hs-Troponin and NP were found in 38% and 56% of the cases respectively. As compared to those with normal cardiac biomarkers, these patients were older, had higher prevalence of cardiovascular diseases (CVD) and more severe COVID-19 pneumonia by higher CRP and D-dimer and lower PaO2/FIO2. Two-dimensional echocardiography performed in a subset of patients (n = 24) showed significantly reduced left ventricular ejection fraction in patients with elevated NP only (p = 0.02), whereas right ventricular systolic function (tricuspid annular plane systolic excursion) was significantly reduced both in patients with high hs-Troponin and NP (p = 0.022 and p = 0.03 respectively). On multivariable analysis, independent associations were found of hs-Troponin with age, PaO2/FIO2 and D-dimer (B = 0.419, p = 0.001; B=-0.212, p = 0.013 and B = 0.179, p = 0.037 respectively), and of NP with age and previous CVD (B = 0.480, p &lt; 0.001 and B = 0.253, p = 0.001 respectively). In patients with in-hospital mortality (n = 23, 21%) hs-Troponin and NP were both higher (p = 0.001 and p = 0.002 respectively), while increasing hs-troponin and NP were associated with worse in-hospital prognosis [OR 4.88 (95% CI 1.9-12.2), p = 0.001 (adjusted OR 3.1 (95% CI 1.2-8.5), p = 0.025) and OR 4.67 (95% CI 2-10.8), p &lt; 0.001 (adjusted OR 2.89 (95% CI 1.1-7.9), p = 0.04) respectively]. Receiver operator characteristic curves showed good ability of hs-Troponin and NP in predicting in-hospital mortality (AUC = 0.869 p &lt; 0.001 and AUC = 0.810, p &lt; 0.001 respectively). Conclusion myocardial involvement at admission is common in COVID-19 pneumonia and associated to worse prognosis, suggesting a role for cardiac biomarkers assessment in COVID-19 risk stratification. Independent associations of hs-Troponin with markers of disease severity and of NP with underlying CVD might point towards existing different mechanisms leading to their elevation in this setting.

Abstract Funding Acknowledgements Type of funding sources: None. Background Plasma levels and N-terminal pro B-type natriuretic peptide (NT- proBNP), a cardiac neurohormone released in response to increased ventricular stress, represent an important predictor of clinical outcomes and left ventricular (LV) dysfunction; Although, its diagnostic and prognostic role in patients with acute myocarditis is not completely established; Our aim was to evaluate the relationship of BNP levels and LV ejection fraction (LVEF) in patients with myocarditis; Methods Data from patients (pts) discharged with the diagnosis of myocarditis, from 2008 and 2018 were retrospectively analysed. Results 62 pts were included. Mean age was 39.7 17 years and 89% (58 patients) were men. Plasma levels of NT-proBNP measured at admission ranged from 24 to 3110 pg/mL (median 514, IQR 947), and exceeded upper normal levels in 51 pts (82%). This values positively correlated with C- reactive protein (CRP) (p= 0.005, r = 0.36), leucocytes (p = 0.03, r= 0.37) and neutrophil-to-lymphocyte ratio (p= 0.05, r= 0.35), but not with left ventricular ejection fraction (LVEF) (p= 0.829). Higher levels of BNP were associated with higher troponin peak levels but not with increased mortality (p = 0.811), need of inotropic support (p= 0.059) or arrhythmic events (p= 0.130). Inflammatory parameters were significantly increased when BNP&gt; 514 pg/mL vs BNP &lt;514 pg/mL (CRP 7.2 vs 4 mg/dL, p= 0.008). This relationship was maintained at BNP &gt; 900. LVEF was comparable in both groups (p = 0.938); In this population, the magnitude of recovery of the NT- proBNP values (variation between NT-proBNP at admission and discharge) strongly correlated with the magnitude of the inflammatory markers at admission (all p &lt; 0,005) Conclusion In patients with acute myocarditis, there is a significant relationship between NT-proBNP levels and inflammation (as measured by leucocytes, NLR or CRP), but not with LVEF; Despite the limitation of a small sample size, we could hypothesize that NTproBNP in this subset of patients appears to be regulated not only by hemodynamic changes but also by the underlying systemic inflammatory process and, therefore, it interpretation should take that into account;

Introduction: Dengue, a vector borne viral infection transmitted by Aedes mosquito has recently become a major public health concern in the tropical regions of the world. In addition to the two major life threatening complications- Dengue Haemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS), a variety of cardiac complications have been recognised, the most common being myocarditis. Aim: To study and compare the quantity of different cardiac biomarkers in patients of Dengue Fever with and without myocarditis. Materials and Methods: This was a hospital-based retrospective observational study done in a Tertiary Care Hospital, Kolkata, West Bengal, India from June 2019 to November 2019. Dengue patients with diagnosed myocarditis on day 7 of fever based on electro and echocardiogram changes of left ventricular ejection fraction less than 50% were considered as cases (n=41). Age and sex matched dengue patients with normal electro and echocardiogram changes were considered as control (n=43). After obtaining Institutional Ethics Committee Clearance, laboratory data were collected from samples coded and assayed for markers of acute cardiac myocyte damage such as total Creatine Kinase (CK), CK-Muscle Brain (CK-MB), Troponin T (Trop T) and cardiac failure biomarker N-Terminal pro Brain Natriuretic Peptide (NT-proBNP). Statistical analysis of the data was performed using Statistical Package for Social Sciences (SPSS 20). Results: Cardiac biomarkers CK, CK-MB, Trop T and NT-proBNP levels in cases were higher compared to controls (p-value <0.05). Trop T and NT-proBNP were positively correlated to each other (r-value: 0.44). Trop T changes could also predict significantly the rise in NT-proBNP in circulation (p<0.05). Conclusion: It reconfirmed the need of routine monitoring of cardiac biomarkers in conjunction with other cardiac function tests in early diagnosis and or management of myocarditis, a severe complication of Dengue Viral Infection (DENV).

The aim of the study was to investigate the features of clinically suspected myocarditis complicated by the left ventricular systolic dysfunction development. 93 patients with clinically suspected myocarditis were examined. The average age was 36.63 ± 1.15 years. In 43.01 % of patients the disease was accompanied by a decrease in left ventricular systolic function. In the group of patients with left ventricular systolic dysfunction in comparison with those with preserved left ventricular ejection fraction, a significantly lower proportion of men (75 % versus 81 %, respectively, χ2 = 9.3, p < 0,01) and a higher average group age (40.7 ± 1.87 versus 33.6 ± 1.3 years, respectively, p <  0,01) were revealed. The course of the disease in patients with left ventricular systolic dysfunction was characterized by a more frequent development of rhythm disturbances (65 % versus 43.3 %, respectively, χ2  = 4.3, p  < 0,05) and a higher heart rate at admission (94.5 (75‒100) and 85 (70‒89) beats per minute, respectively, p = 0.006). The structural and functional state of the heart according to echocardiography in patients with a reduced left ventricular ejection fraction versus comparison group was characterized by larger heart chambers sizes, more pronounced violations of local left ventricular contractility, more frequent involvement of the right ventricle in the pathological process (56.3  % versus 22.2  %, respectively, χ2   =  6.4, p  < 0,05).

Takotsubo cardiomyopathy is a rare syndrome characterized by acute left ventricular dysfunction with regional left ventricular ballooning, mimicking myocardial infarction. This condition is often described in post-menopausal women. Authors present a case in an elderly primi with twin gestation immediately after Cesarean surgery. We discussed her presentation, investigations, diagnosis, management and outcome. 35 year female, a primi with twin pregnancy developed chest pain and shortness of breath immediately after Cesarean surgery. Her Electrocardiograph was abnormal, and Echocardiogram demonstrated abnormal apical ballooning of the left ventricle and severe dysfunction. Cardiac enzymes were elevated and chest skiagram showed pulmonary edema. She was managed in the intensive care unit with oxygen supplementation, diuretics and inotropes. She made an excellent recovery with normalization of left ventricular ejection fraction within 8 days. During the six months follow up, she was asymptomatic and left ventricular function remained normal.

Introduction: Reductions in left ventricular ejection fraction (LVEF) may occur after the administration of anthracycline-based chemotherapeutic regimens. Oxidative stress at the myocellular level has been implicated in these reductions, and as a consequence, we hypothesized that bilirubin, an effective endogenous anti-oxidant, would ameliorate some of the reductions in LVEF associated with anthracyline administration. Methods: From 1/1/2002 to 12/31/2012, we identified 751 consecutive individuals who were treated with anthracyclines at Wake Forest Baptist Medical Center, received serial LVEF measures, and exhibited basal serum bilirubin levels < 2mg/dl prior to their treatment for cancer. The correlation between pre-chemotherapy bilirubin levels and serial pre- to post-chemotherapy changes in LVEF was analyzed using linear regression models. For dose response analysis, the participants were divided into 3 groups based on their bilirubin levels. ANOVA was used to test for the difference in the mean LVEF change across groups. Tukey’s Studentized Range test was used in pairwise comparisons. Chi-square test was used for categorical variables. Results: There were 65 (35%), 86 (30%) and 68 (24%) participants whose LVEF decreased by more than 15% in Group 1 (bilirubin ≤0.5mg/dl), Group2 (bilirubin 0.6 - 0.8mg/dl) and Group 3 (bilirubin 0.9 - 1.9mg/dl) respectively (Table 1). On pairwise comparison, there was a significant decrease in LVEF between Group 1 and Group 3 (2.9, 95% CI: 0.15 - 5.7). After adjusting for age, BMI, race, CAD/MI, diabetes, hematocrit and medications; increased bilirubin and reduced BMI were associated with LVEF preservation (p = 0.028 and 0.033 respectively). Conclusions: In patients treated with anthracyclines, bilirubin level was negatively correlated with reduction in LVEF. These results have potential therapeutic implications for preserving left ventricular function in patients treated with anthracyclines.

Abstract Introduction The CARISMA trial was the first study to use continuous monitoring for documentation of long-term arrhythmias in post-infarction patients with left ventricular dysfunction. During the study duration (2000–2005), primary PCI (pPCI) as treatment of acute myocardial infarction was introduced approximately midway (2002) on the enrolling centres. Purpose The aim of this study was to describe the influence of mode of revascularization after myocardial infarction (AMI) on long-term risk of risk of new onset atrial fibrillation, ventricular tachyarrhythmias and brady arrhythmias. Methods The study is a sub-study on the CARISMA study population that consisted of patients with AMI and left ventricular ejection fraction ≤40%, which received an implantable loop recorder and was followed for 2 years. After exclusion of 15 patients who refused device implantation and 26 with pre-existing arrhythmias, 268 of the 312 patients were included. Choice of revascularization was made by the treating team independently of the trial and was retrospectively divided into primary percutaneous intervention (pPCI), subacute PCI (24 hours to 2 weeks after AMI), primary thrombolysis or no revascularization. Endpoints were new-onset of arrhythmias and major cardiovascular events (MACE). The Kaplan-Meier (figure 1) and Mantel-Byar methods were used for time to first event risk analysis. Results A total of 77 patients received no revascularization, whereas 49 received thrombolysis only and 142 received PCI. At two-years follow up patients treated with any PCI had a significant lower risk (0.40, n=63) of any arrhythmia compared to patients treated with trombolysis (0.60, n=30) or no revascularization (0.68, n=16) (p<0.001, unadjusted) (figure 1). Risk of MACE was significant higher in patients with any arrhythmia (0.25, n=76) compared to no arrhythmia (0.11, n=93) at two years follow-up (p=0.004, unadjusted). Figure 1 Conclusion(s) The long-term risk of new onset arrhythmias after AMI was significantly lower in patients treated with any PCI compared to patients not revascularized or treated with thrombolysis. Risk of MACE was significantly higher in patients with new onset arrhythmias compared to patients with no arrhythmias.
