RESUMO

BACKGROUND: Cardiovascular complications of severe acute respiratory distress syndrome coronavirus 2 (SARS-CoV2) are known to be associated with poor outcome. A small number of case series and reports have described cases of myocarditis and ischaemic events, however, knowledge on the aetiology of acute cardiac failure in SARS-CoV2 remains limited. We describe the occurrence and risk stratification imaging correlates of 'takotsubo' stress cardiomyopathy presenting in a patient with Coronavirus Disease 2019 (COVID-19) in the intensive care unit. An intubated 53-year old patient with COVID19 suffered acute haemodynamic collapse in the intensive care unit, and was thus investigated with transthoracic echocardiography (TTE), 12-lead electrocardiograms (ECG) and serial troponins and blood tests, and eventually coronary angiography due to clinical suspicion of ischaemic aetiology. Echocardiography revealed a reduced ejection fraction, with evident extensive apical akinesia spanning multiple coronary territories. Troponins and NT-proBNP were elevated, and ECG revealed ST elevation: coronary angiography was thus performed. This revealed no significant coronary stenosis. Repeat echocardiography performed within the following week revealed a substantial recovery of ejection fraction and wall motion abnormalities. Despite requirement of a prolonged ICU stay, the patient now remains clinically stable, and is on spontaneous breathing. CONCLUSION: This case report presents a case of takotsubo stress cardiomyopathy occurring in a critically unwell patient with COVID19 in the intensive care setting. Stress cardiomyopathy may be an acute cardiovascular complication of COVID-19 infection. In the COVID19 critical care setting, urgent bedside echocardiography is an important tool for initial clinical assessment of patients suffering haemodynamic compromise.

RESUMO

Takotsubo cardiomyopathy (TTC), a persistently obscure dysfunctional condition of the left ventricle, is uniquely transient but nevertheless dangerous. It features variable ventricular patterns and is predominant in women. For 30 years, pathophysiologic investigations have progressed only slowly and with inadequate focus. It was initially proposed that sudden-onset spastic obliteration of coronary flow induced myocardial ischemia with residual stunning and thus TTC. Later, it was generally accepted without proof that, in the presence of pain or emotional stress, the dominant mechanism for TTC onset was a catecholamine surge that had a direct, toxic myocardial effect. We think that the manifestations of TTC are more dynamic and complex than can be assumed from catecholamine effects alone. In addition, after reviewing the recent medical literature and considering our own clinical observations, especially on spasm, we theorize that atherosclerotic coronary artery disease modulates and physically opposes obstruction during spasm. This phenomenon may explain the midventricular variant of TTC and the lower incidence of TTC in men. We continue to recommend and perform acetylcholine testing to reproduce TTC and to confirm our theory that coronary spasm is its initial pathophysiologic factor. An improved understanding of TTC is especially important because of the condition's markedly increased incidence during the ongoing COVID-19 pandemic.

RESUMO

Electrocardiographic disturbances in Takotsubo syndrome have been previously partially described but their consequences remain mostly unknown. Our aim was to describe the prevalence and prognostic significance of different electrocardiographic features in patients with Takotsubo syndrome. Our data come from the Spanish multicenter REgistry of TAKOtsubo syndrome (RETAKO). All patients with an available 12-lead surface electrocardiogram at admission and 48 hours post-admission were included. A total of 246 patients were studied, mean age was 71.3 ± 11.5 and 215 (87.4%) were women. ST-segment elevation was seen in 143 patients (59.1%) and was present in ≥2 wall leads in 97 (39.8%). Exclusive elevation in inferior leads was infrequent (5% - 2.0%). After 48 hours, 198 patients (88.0%) developed negative T waves in a median of 8 leads with a mean amplitude of 0.7 ± 0.5 mV and 137 (60.9%) had pathological Q waves. The mean corrected QT interval was 520 ± 72 ms. Corrected QT interval was independently associated with the primary endpoint of all-cause death and nonfatal cardiovascular events (P = 0.002) and all-cause death (P = 0.008). A higher heart rate at admission was an independent predictor of the primary endpoint (P = 0.001) and of acute pulmonary edema (P = 0.04). ST-segment elevation with reciprocal depression was an independent predictor of all-cause death (P = 0.04). Absence of ST-segment deviation was a protective factor (P = 0.005) for the primary endpoint. Tachyarrhythmias were independently associated with cardiogenic shock (P< 0.001). Takotsubo syndrome patients present with distinct electrocardiographic features. Prolonged corrected QT interval, tachyarrhythmias, heart rate at admission, and more extensive repolarization alterations are associated with poor outcomes.

RESUMO

OBJECTIVE: Takotsubo syndrome following cardiac surgery is a rare occurrence. However, early diagnosis is essential to prevent treatment which could increase the left ventricular outflow tract pressure gradient in patients with Takotsubo syndrome, and lead to cardiogenic shock. Therefore, our study aimed to identify the incidence of Takotsubo syndrome after cardiopulmonary bypass and the associated risk factors and prognosis. METHODS: We retrospectively studied 5773 patients who underwent cardiopulmonary bypass between February 2007 and July 2017. Among these, Takotsubo syndrome was diagnosed in 52 (0.9%). To evaluate the risk factors for Takotsubo syndrome, 104 of the remaining 5721 patient were randomly selected as the control group (1:2 ratio). Univariate and multivariate logistic regression analyses were used for risk factor analysis. RESULTS: Majority of patients (69.2%) in the Takotsubo syndrome group underwent mitral valve surgery, compared with 32.7% in the control group. The following risk factors of Takotsubo syndrome were identified: atrio-ventricular valve surgery (odds ratio (OR) 10.5; 95% confidence interval (CI), 2.6-42.5; p = 0.001); and the immediate postoperative use of epinephrine (OR, 3.3; 95% CI, 1.0-10.7; p = 0.05) and dobutamine (OR, 4.8; 95% CI, 1.72-13.3; p = 0.003). Hypertension was a significant protective factor against Takotsubo syndrome following cardiac surgery (OR, 0.22; 95% CI, 0.06-0.73; p = 0.01). CONCLUSION: Takotsubo syndrome following cardiac surgery is rare. Immediate postoperative use of epinephrine and doputamine, as well as atrio-ventricular valve surgery were factors associated with the development of Takotsubo syndrome.

RESUMO

Coronavirus disease 2019 (COVID-19) is a global pandemic impacting nearly 170 countries/regions and millions of patients worldwide. Patients with acute myocardial infarction (AMI) still need to be treated at percutaneous coronary intervention (PCI) centers with relevant safety measures. This retrospective study was conducted to assess the therapeutic outcomes of PCI performed under the safety measures and normal conditions. AMI patients undergoing PCI between January 24 to April 30, 2020 were performed under safety measures for COVID-19. Patients received pulmonary computed tomography (CT) and underwent PCI in negative pressure ICU. Cardiac catheterization laboratory (CCL) staff and physicians worked with level III personal protection. Demographic and clinical data, such as door-to-balloon (DTB) time, operation time, complications for patients in this period (COVID-19 group) and the same period in 2019 (2019 group) were retrieved and analyzed. COVID-19 and 2019 groups had 37 and 96 patients, respectively. There was no significant difference in age, gender, BMI and comorbidity between the two groups. DTB time and operation time were similar between the two groups (60.0 ± 12.39 vs 58.83 ± 12.85 min, p = 0.636; 61.46 ± 9.91 vs 62.55 ± 10.72 min, p = 0.592). Hospital stay time in COVID-19 group was significantly shorter (6.78 ± 2.14 vs 8.85 ± 2.64 days, p < 0.001). The incidences of malignant arrhythmia and Takotsubo Syndrome in COVID-19 group were higher than 2019 group significantly (16.22% vs 5.21%, p = 0.039; 10.81% vs 1.04% p = 0.008). During hospitalization and 3-month follow-up, the incidence of major adverse cardiovascular events and mortality in the two groups were statistically similar (35.13% vs 14.58%, p = 0.094; 16.22% vs 8.33%, p = 0.184). The risk of major adverse cardiac events (MACE) was associated with cardiogenic shock (OR, 11.53; 95% CI, 2.888-46.036; p = 0.001), malignant arrhythmias (OR, 7.176; 95% CI, 1.893-27.203; p = 0.004) and advanced age (≥ 75 years) (OR, 6.718; 95% CI, 1.738-25.964; p = 0.006). Cardiogenic shock (OR, 17.663; 95% CI, 5.5-56.762; p < 0.001) and malignant arrhythmias (OR, 4.659; 95% CI, 1.481-14.653; p = 0.008) were also associated with death of 3 months. Our analysis showed that safety measures undertaken in this hospital, including screening of COVID-19 infection and use of personal protection equipment for conducting PCI did not compromise the surgical outcome as compared with PCI under normal condition, although there were slight increases in incidence of malignant arrhythmia and Takotsubo Syndrome.

RESUMO

BACKGROUND: Catecholamine excess arising from pheochromocytomas and paragangliomas (PPGLs) can cause a wide spectrum of cardiac manifestations, including acute cardiac complications (ACCs) and subclinical myocardial injuries (SMIs). In this study, we aimed to conduct a comprehensive analysis of ACCs and SMIs in a large cohort of patients with PPGLs. METHODS: We retrospectively analyzed the clinical data of consecutive patients with PPGLs admitted between January 2013 and July 2020 (n = 189). The prevalence of ACCs and SMIs and characteristics of patients identified with ACCs and SMIs were investigated. Moreover, comparisons were performed between patients with and without ACCs. RESULTS: Fourteen patients (7.4%) fulfilled the criteria for ACCs, including nine (4.8%) who presented with Takotsubo-like cardiomyopathy, four (2.1%) with heart failure with preserved ejection fraction, and finally one (0.5%) with catecholamine-induced cardiomyopathy. Compared to those without ACCs (n = 175), patients with ACCs had a higher prevalence of epinephrine-producing PPGLs (81.8% vs 33.9%, P = 0.006) and were more likely to show invasive behavior (61.5% vs 27.3%, P = 0.022) or hemorrhage/necrosis (53.9% vs 17.4%, P = 0.005) on histology. The apical sparing pattern (5/7, 71.4%) was the dominant impairment pattern of longitudinal strain (LS) for patients displaying Takotsubo-like cardiomyopathy. In patients without cardiac symptoms, a fairly high proportion (21/77, 27.3%) of patients who underwent screening for troponin and/or natriuretic peptide and/or echocardiography had SMIs. CONCLUSIONS: One in every fourteen PPGL patients presented with ACCs, and in the patients with Takotsubo-like cardiomyopathy, the apical sparing pattern was the primary impairment pattern of LS. Additionally, nearly one-third of patients without symptoms had SMIs. The diagnosis of PPGLs should be considered in patients with acute reversible cardiomyopathy, especially in those exhibiting an apical sparing pattern of LS.

RESUMO

AIMS: Acute pulmonary disorders are known physical triggers of takotsubo syndrome (TTS). This study aimed to investigate prevalence of acute pulmonary triggers in patients with TTS and their impact on outcomes. METHODS AND RESULTS: Patients with TTS were enrolled from the International Takotsubo Registry and screened for triggering factors and comorbidities. Patients were categorized into three groups (acute pulmonary trigger, chronic lung disease, and no lung disease) to compare clinical characteristics and outcomes. Of the 1670 included patients with TTS, 123 (7%) were identified with an acute pulmonary trigger, and 194 (12%) had a known history of chronic lung disease. The incidence of cardiogenic shock was highest in patients with an acute pulmonary trigger compared with those with chronic lung disease or without lung disease (17% vs. 10% vs. 9%, P = 0.017). In-hospital mortality was also higher in patients with an acute pulmonary trigger than in the other two groups, although not significantly (5.7% vs. 1.5% vs. 4.2%, P = 0.13). Survival analysis demonstrated that patients with an acute pulmonary trigger had the worst long-term outcome (P = 0.002). The presence of an acute pulmonary trigger was independently associated with worse long-term mortality (hazard ratio 2.12, 95% confidence interval 1.33-3.38; P = 0.002). CONCLUSIONS: The present study demonstrates that TTS is related to acute pulmonary triggers in 7% of all TTS patients, which accounts for 21% of patients with physical triggers. The presence of acute pulmonary trigger is associated with a severe in-hospital course and a worse long-term outcome.

RESUMO

AIMS: Takotsubo syndrome (TTS) is a form of acute myocardial inflammation, often triggered by catecholamine release surges, which accounts for approximately 10% of 'myocardial infarctions' in female patients above the age of 50. Its associated substantial risk of in-hospital mortality is mainly driven by the development of hypotension and shock. While hypotension is induced largely by factors other than low cardiac output, its precise cause is unknown, and clinical parameters associated with hypotension have not been identified previously. We therefore sought to identify the incidence and clinical/laboratory correlates of early hypotension in TTS. METHODS AND RESULTS: We analysed the in-hospital data of patients recruited to the South Australian TTS Registry. Associations between the development of hypotension, patient demographics, severity of the acute TTS attack, and key biochemical markers were sought. One hundred thirteen out of 319 patients (35%) were hypotensive (median systolic blood pressure 80 mmHg) during their index hospitalization. Development of hypotension preceded all in-hospital deaths (n = 8). On univariate analyses, patients who developed hypotension had lower left ventricular ejection fraction (P = 0.009), and higher plasma N-terminal pro brain natriuretic peptide and troponin-T concentrations (P = 0.046 and 0.008, respectively), all markers of severity of the TTS attack; hypotension also occurred less commonly in male than in female patients (P = 0.014). On multivariate linear regression analysis, female sex and lower left ventricular ejection fraction were independent correlates of the development of hypotension (P = 0.009 and 0.010, respectively). CONCLUSIONS: Early development of hypotension is very common in TTS, and its presence is associated with a substantial risk of in-hospital mortality. Hypotension is a marker of severe TTS attacks and occurs more commonly in female TTS patients.

RESUMO

In the course of COVID-19 pandemic, many patients with diagnosed or suspected disease do require echocardiography. At the same time, when it comes to the echocardiographers, there is a fear of their being exposed to contamination. At COVID-19-dedicated hospital examinations are bedside, and in some patients hand-held or tablet-based echocardiography should be preferred; the echocardiographer routinely puts on a complete protective uniform. The prevalence of stress-induced takotsubo syndrome (TTS) during the Covid-19 pandemic is higher than previously reported. The authors present the images obtained using tabletbased limited echocardiography in patients with different forms of TTS. The time of the examination of patients and decontamination of the equipment was short (5-7 min and less than 2 min, respectively); the images were of fairly good quality.

RESUMO

Objective The aim of this study was to clarify the circadian and seasonal variations in addition to identify sex-based differences in Japanese patients with Takotsubo syndrome (TTS). Methods The authors conducted a retrospective observational study to analyse the differences between the groups based on sex. Patients The patients were registered out of each institute registry of the acute coronary syndrome (ACS) which contains a total of 10,622 cases in eight academic hospitals in east Japan. Results Data for 344 consecutive TTS (73 male and 271 female) were extracted from each hospital registry. In-hospital mortality was higher in the male group than in the female group (18% vs. 7%; p=0.005). With regard to the circadian variations in all study patients, TTS events occurred most often in the afternoon and least often during the night. Moreover, the patterns of circadian variations in the female and male groups were the same as that of all study patients. TTS events occurred most frequently in the autumn and least often in the spring in the whole study cohort. Moreover, the seasonal variation in the female group showed the same pattern as that of the whole cohort. However, there were no significant seasonal differences in the incidence of TTS in the male group. Conclusion In a multicenter study in Japan, seasonal variation was observed in the female group but not in the male group. Circadian variation was observed in both groups. These results suggested that the pathogenesis and clinical features of TTS might therefore differ according to sex.

RESUMO

The association between anemia and Takotsubo cardiomyopathy (TCM) has not been well studied. To assess the effect of anemia on patients hospitalized with TCM, we identified 4733 patients with a primary diagnosis of TCM from the 2016 to 2018 National Inpatient Sample (NIS) database (the United States) using the International Classification of Diseases, 10th edition, Clinical Modification (ICD-10-CM) code. Of these, 603 (12.7%) patients had a comorbidity of anemia and 4130 did not. After propensity score matching, we compared the in-hospital outcomes between the 2 groups (anemia vs nonanemia, n = 594 vs 1137). Patients with TCM with anemia had significantly higher rates of in-hospital complications, including cardiogenic shock (11.4% vs 4.0%, P < .001), ventricular arrhythmia (6.6% vs 3.6%, P = .008), acute kidney injury (22.7% vs 13.1%, P < .001), acute respiratory failure (22.6% vs 13.1%, P < .001), longer length of hospital stay (5.6 ± 5.8 days vs 3.6 ± 3.6 days, P < .001), and higher total charges (US$79 586 ± 10 2436 vs US$50 711 ± 42 639, P < .001). In conclusion, patients with anemia who were admitted for TCM were associated with a higher incidence of in-hospital complications compared with those without anemia.

RESUMO

BACKGROUND: Previous small-scale studies have reported conflicting findings regarding the prevalence of diabetes mellitus (DM) and its association with outcomes in patients with takotsubo syndrome (TTS) OBJECTIVE: We sought to assess the prevalence of DM and its association with outcomes in TTS patients. METHODS: Nationwide inpatient sample (NIS) was queried to extract patient information from January 1, 2009 to September 30, 2015. Propensity score matching (PSM) was done to compare mortality and other in-hospital outcomes. RESULTS: A total of 40,327 hospitalizations for TTS were included. The prevalence of DM in TTS was 19.3% vs 23.1% (p-value < 0.01) in patients without TTS in the NIS from 2009 to 2015. In the PSM cohort, there was no difference in in-hospital mortality (1.1% vs 1.4%; p = 0.76), stroke (1.2% vs 0.9%; p = 0.09), cardiogenic shock (3.7% vs 3.9%; p = 0.61), cardiac arrest (1.2% vs 1.2%; p = 0.94), ventricular arrhythmias (3.7% vs 3.3%; p = 0.23), circulatory support (2.1% vs 1.8%; p = 0.17), and invasive mechanical ventilation (4.9% vs 4.7%; p = 0.54) in TTS patients with versus without diabetes. In sub-group analysis, diabetes with chronic complications patients were found to have lower mortality (0.7% vs 2.0%; p = 0.04) compared to patients without diabetes and those with uncomplicated diabetes (0.6% vs 2.6%; p = 0.002). CONCLUSIONS: Prevalence of DM was lower in TTS in comparison to patients without TTS. In addition, complicated DM patients were found to have lower in-hospital mortality. Further studies are needed to assess the mid and long-term outcomes of DM with and without chronic complications in TTS.

RESUMO

AIMS: The risk of life-threatening ventricular arrhythmias (LTVA) has been reported to be lower in Takotsubo syndrome (TS) compared with ST-elevation myocardial infarction (STEMI). However, the extent to which these differences relate to the fact that most patients with TS are women (who have a lower risk of LTVA) and a relatively larger proportion of patients with STEMI are men is incompletely understood. We aimed to investigate the risk of LTVA or death in sex-matched and age-matched patients with TS, anterior STEMI, and non-anterior STEMI. METHODS AND RESULTS: We systematically reviewed the charts of all patients with TS who were treated at Sahlgrenska University Hospital (Gothenburg, Sweden) between 2008 and 2019. A total of 155 patients with confirmed TS (according to the European Society of Cardiology diagnostic criteria for TS) were sex-matched and age-matched 1:1:1 to patients with anterior and non-anterior STEMI. Baseline characteristics and in-hospital outcomes were recorded directly from the patient charts for all patients, and all admission electrocardiographs were analysed. The primary outcome was the composite of death or LTVA [defined as sustained ventricular tachycardia (>30 s) or ventricular fibrillation] within 72 h. The risk of LTVA or death within 72 h after admission was considerably lower in TS (2.6%) vs. anterior STEMI (14%; P = 0.002) and non-anterior STEMI (9.0%; P = 0.02), despite similar or greater risks of acute heart failure, and similar risks of cardiogenic shock. Compared with STEMI, TS was associated with a lower risk of sustained and non-sustained ventricular tachycardia and ventricular fibrillation. CONCLUSIONS: In a predominantly female age-matched and sex-matched cohort of patients with TS, anterior STEMI, and non-anterior STEMI, the adjusted risk of in-hospital LTVA or death was considerably lower in TS compared with STEMI, despite similar or greater risk of acute heart failure and similar risk of cardiogenic shock.

RESUMO

PURPOSE: Takotsubo cardiomyopathy, also called apical ballooning syndrome, is characterized by regional left ventricular systolic dysfunction that resembles myocardial infarction in its initial presentation; however, it lacks angiographic evidence of coronary artery disease. We evaluated the incidence of takotsubo cardiomyopathy following liver transplant at a diverse urban transplant program. METHODS: This is a retrospective review of patients transplanted at a single center between 2017 and 2019. Here we report 2 cases of takotsubo cardiomyopathy that developed after liver transplantation. RESULTS: A 65-year-old woman diagnosed with alcoholic cirrhosis underwent a brain-dead donor liver transplant. The postoperative course was complicated by stroke, pulmonary hypertension, and a left internal jugular thrombus. Six months following transplant, the patient developed takotsubo cardiomyopathy with congestive hepatopathy and died of heart failure complications despite maximal medical care. The second case was a 65-year-old woman with alcoholic cirrhosis admitted for a living donor liver transplant. The postoperative period involved recurrent seizures and elevated troponins with markedly reduced ejection fraction, which were appropriately managed. The patient recovered well with supportive care and was discharged to a rehabilitation facility shortly after. CONCLUSION: We present a series of patients with takotsubo cardiomyopathy after liver transplantation. The diagnosis depends on the clinical presentation and findings on electrocardiography, echocardiography, and cardiac enzymes. Our patients met the Mayo Clinic diagnostic criteria and were appropriately managed according to guidelines. Our report highlights the possibility of pulmonary hypertension contributing to the development of takotsubo cardiomyopathy. Additional studies are needed to establish a definite correlation.
