Heart and lung, a dangerous liaison-Tako-tsubo cardiomyopathy and respiratory diseases: A systematic review

Takotsubo Syndrome-Induced Cardiogenic Shock in Lung Transplantation: Importance of Early Diagnosis and ECMO Implantation

BACKGROUND Takotsubo syndrome, or stress-induced cardiomyopathy, is a rare but serious condition that mimics myocardial infarction and can cause temporary cardiac dysfunction in the absence of coronary artery disease. General anesthesia can make diagnosis more challenging. Although it has already been described in a context of solid organ transplantation, takotsubo syndrome remains under-reported in lung transplantation, necessitating awareness to avoid diagnostic and management delays. CASE REPORT We report a case of takotsubo syndrome in a 54-year-old woman undergoing pulmonary transplantation for end-stage chronic obstructive pulmonary disease. Preoperative evaluations showed no cardiac pathology. During surgery, she developed severe left ventricular failure with ST-segment elevations and diffuse hypokinesia, leading to cardiogenic shock and multiorgan dysfunction. Delayed diagnosis of takotsubo syndrome and late initiation of veno-arterial extracorporeal membrane oxygenation worsened her condition. Postoperatively, she developed lung abscesses, broncho-cutaneous fistula, and hemorrhagic shock, resulting in a prolonged intensive care unit stay. Two years after the transplant, left ventricular dysfunction was persistent, significantly affecting her quality of life. CONCLUSIONS This case report highlights the importance of awareness of takotsubo syndrome associated with lung transplantation, particularly in at-risk patients. Indeed, early diagnosis and management of this cardiomyopathy are crucial for improving outcomes. Multimodal monitoring, including transesophageal echocardiography and continuous ST-segment monitoring, is essential for timely diagnosis. Although rare, this complex clinical condition should be considered in lung transplant recipients with sudden heart failure to ensure prompt and effective treatment. Further research is needed to understand this stress cardiomyopathy in this specific setting and to develop effective management strategies.

A Case of Takotsubo Syndrome in a Smoker-Epileptic Patient With Rhinovirus Pneumonia in the Intensive Care Unit: Could the InterTAK Criteria Be Useful?

Takotsubo syndrome (TS) is an acute cardiac dysfunction that typically presents hypokinesis of the apical segment of the left ventricle beyond a single coronary artery territory. The pathological mechanisms of TS remain unclear, and several possible theories have been postulated, including catecholamine excess, coronary artery spasm, microvascular dysfunction, and metabolic disturbances. Based on the etiology, a primary and secondary form is distinguished. In primary TS, acute cardiac symptoms are the primary reason for seeking acute medical care. In secondary TS, the syndrome occurs in patients already hospitalized for a medical or surgical condition. The clinical conditions most frequently associated with TS are respiratory pathologies, sepsis, neurological disease, endocrine disease, and psychiatric pathologies. The incidence of TS is poorly studied in the critically ill patient setting; furthermore, it is very difficult to determine its incidence, duration, and progression from the current literature. We present the clinical case of a secondary TS in a smoker patient with a history of epilepsy, hospitalized in the ICU for respiratory failure due to viral pneumonia, complicated with bronchospasm, highlighting the diagnostic difficulties in critically ill patients, the presence of multiple trigger factors, and the need to perform an early diagnosis for patient survival.

Onset of takotsubo syndrome induced by osimertinib in a patient with lung adenocarcinoma

The cardiotoxicity of osimertinib, an epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor, has been recently reported when treating EGFR mutation-positive non-small cell lung cancer. In this report, we describe a case of an 81-year-old female patient diagnosed with Takotsubo syndrome (TTS). TTS occurred despite the patient receiving osimertinib retreatment at reduced doses and having no history of cardiac or respiratory disease. The findings of this case suggest that clinicians should consider the possibility of TTS induced by osimertinib.

Incidence and Impact of Takotsubo Syndrome in Hospitalized Patients With COVID-19

BACKGROUND

Takotsubo syndrome has been reported in patients with COVID-19, although minimal data are available. This investigation assessed the incidence and impact of takotsubo syndrome on patients hospitalized with COVID-19.

METHODS

A retrospective cohort study was conducted using International Statistical Classification of Diseases, Tenth Revision, codes to identify patients with a primary diagnosis of COVID-19 with or without takotsubo syndrome in the National Inpatient Sample 2020 database. Outcomes between groups were compared after propensity score matching for patient and hospital demographics and comorbidities.

RESULTS

A total of 211,448 patients with a primary diagnosis of COVID-19 were identified. Of these, 171 (0.08%) had a secondary diagnosis of takotsubo syndrome. Before matching, patients with COVID-19 and takotsubo syndrome, compared with patients without takotsubo syndrome, were older (68.95 vs 64.26 years; P < .001); more likely to be female (64.3% vs 47.2%; P < .001); and more likely to have anxiety (24.6% vs 12.8%; P < .001), depression (17.5% vs 11.4%; P = .02), and chronic obstructive pulmonary disease (24.6% vs 14.7%; P < .001). The takotsubo syndrome group had worse outcomes than the non-takotsubo syndrome group for death (30.4% vs 11.1%), cardiac arrest (7.6% vs 2.1%), cardiogenic shock (12.9% vs 0.4%), length of hospital stay (10.7 vs 7.5 days), and total charges ($152,685 vs $78,468) (all P < .001). After matching and compared with the non-takotsubo syndrome group (n = 508), the takotsubo syndrome group (n = 170) had a higher incidence of inpatient mortality (30% vs 14%; P < .001), cardiac arrest (7.6% vs 2.8%; P = .009), and cardiogenic shock (12.4% vs 0.4%; P < .001); a longer hospital stay (10.7 vs 7.6 days; P < .001); and higher total charges ($152,943 vs $79,523; P < .001).

CONCLUSION

Takotsubo syndrome is a rare but severe in-hospital complication in patients with COVID-19.

Takotsubo (stress) cardiomyopathy induced by acute asthma exacerbation in elderly woman

A 73-year-old patient who was admitted secondary to acute asthma exacerbation that required frequent salbutamol and adrenaline nebulization. Takotsubo cardiomyopathy (TTC) was diagnosed after the new onset of chest pain with modest troponin elevation and normal coronary angiogram. Low ejection fraction and apical akinesia were completely resolved after her symptoms got improved.

Oxidative Stress in Takotsubo Syndrome-Is It Essential for an Acute Attack? Indirect Evidences Support Multisite Impact Including the Calcium Overload-Energy Failure Hypothesis

Indirect evidences in reviews and case reports on Takotsubo syndrome (TTS) support the fact that the existence of oxidative stress (OS) might be its common feature in the pre-acute stage. The sources of OS are exogenous (environmental factors including pharmacological and toxic influences) and endogenous, the combination of both may be present, and they are being discussed in detail. OS is associated with several pathological conditions representing TTS comorbidities and triggers. The dominant source of OS electrones are mitochondria. Our analysis of drug therapy related to acute TTS shows many interactions, e.g., cytostatics and glucocorticoids with mitochondrial cytochrome P450 and other enzymes important for OS. One of the most frequently discussed mechanisms in TTS is the effect of catecholamines on myocardium. Yet, their metabolic influence is neglected. OS is associated with the oxidation of catecholamines leading to the synthesis of their oxidized forms - aminochromes. Under pathological conditions, this pathway may dominate. There are evidences of interference between OS, catecholamine/aminochrome effects, their metabolism and antioxidant protection. The OS offensive may cause fast depletion of antioxidant protection including the homocystein-methionine system, whose activity decreases with age. The alteration of effector subcellular structures (mitochondria, sarco/endoplasmic reticulum) and subsequent changes in cellular energetics and calcium turnover may also occur and lead to the disruption of cellular function, including neurons and cardiomyocytes. On the organ level (nervous system and heart), neurocardiogenic stunning may occur. The effects of OS correspond to the effect of high doses of catecholamines in the experiment. Intensive OS might represent "conditio sine qua non" for this acute clinical condition. TTS might be significantly more complex pathology than currently perceived so far.

Prognostic impact of acute pulmonary triggers in patients with takotsubo syndrome: new insights from the International Takotsubo Registry

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.

Eosinopenia and neutrophil-to-lymphocyte count ratio as prognostic factors in exacerbation of COPD

Exacerbations of Chronic Obstructive Pulmonary Disease (AECOPDs) are one of the most important clinical aspects of the disease, and when requiring hospital admission, they significantly contribute to mortality among COPD patients. Our aim was to assess the role of eosinopenia and neutrophil-to-lymphocyte count (NLR) as markers of in-hospital mortality and length of hospitalization (LoH) among patients with ECOPD requiring hospitalization. We included 275 patients. Eosinopenia was associated with in-hospital deaths only when coexisted with lymphocytopenia, with the specificity of 84.4% (95% CI 79.6-88.6%) and the sensitivity of 100% (95% CI 35.9-100%). Also, survivors presented longer LoH (P < 0.0001). NLR ≥ 13.2 predicted in-hospital death with the sensitivity of 100% (95% CI 35.9-100%) and specificity of 92.6% (95% CI 88.8-95.4%), however, comparison of LoH among survivors did not reach statistical significance (P = 0.05). Additionally, when we assessed the presence of coexistence of eosinopenia and lymphocytopenia first, and then apply NLR, sensitivity and specificity in prediction of in-hospital death was 100% (95% CI 35.9-100) and 93.7% (95% CI 90.1-96.3), respectively. Moreover, among survivors, the occurrence of such pattern was associated with significantly longer LoH: 11 (7-14) vs 7 (5-10) days (P = 0.01). The best profile of sensitivity and specificity in the prediction of in-hospital mortality in ECOPD can be obtained by combined analysis of coexistence of eosinopenia and lymphocytopenia with elevated NLR. The occurrence of a such pattern is also associated with significantly longer LoH among survivors.

The Association Between Hyperlipidemia and In-Hospital Outcomes in Takotsubo Cardiomyopathy

PURPOSE

Hyperlipidemia (HLD) is one of the most common cardiovascular risk factors and is prevalent in patients with takotsubo cardiomyopathy (TCM), but the association between HLD and TCM patients' outcomes is unclear. We investigated the impact of HLD on the in-hospital outcomes of TCM patients.

PATIENTS AND METHODS

Our retrospective cohort study used the latest available data from the National Inpatient Sample (2016-2017). Using the ICD-10 code, we identified 3139 patients with a primary diagnosis of TCM, 1530 of whom had HLD. We compared in-hospital outcomes between HLD and non-HLD groups before and after propensity score matching.

RESULTS

In the unmatched cohort, the HLD group had lower incidences of cardiac arrest, cardiogenic shock, and acute respiratory failure (ARF); shorter length of stay (LOS); and lower total charges (All p<0.05). In-hospital mortality (p=0.102) and ventricular arrhythmia (p=0.235) rates did not differ. After propensity score matching, the HLD group had lower rates of in-hospital mortality (1.1% vs 2.4%, p=0.027), ARF (9.1% vs 12.1%, p = 0.022) and cardiogenic shock (3.4% vs 5.6%, p=0.012), shorter LOS (3.20 ± 3.27 days vs 3.57 ± 3.14 days, p=0.005), and lower total charges (p=0.013). The matched groups did not differ significantly regarding cardiac arrest (p=0.141), ventricular arrhythmia (p=0.662) or acute kidney injury (AKI) (p = 0.167).

CONCLUSION

Counterintuitively, HLD was associated with better in-hospital outcomes in both the unmatched and propensity-matched cohorts of hospitalized TCM patients. Further studies are needed to investigate the mechanisms that may contribute to the association in TCM patients with HLD.

Takotsubo cardiomyopathy and pituitary apoplexy: a case report

Background

Takotsubo cardiomyopathy (TTC) has been widely recognized in recent decades and is triggered by either physical or psychological stressors.

Case presentation

A 70-year-old woman presented to the Emergency Department due to confusion, hypotension, fever, chills, and cough. She had a one-year history of diabetes insipidus. Pituitary function examination at admission revealed decreased thyroid, sex and adrenal hormones. Pituitary MRI displayed findings suggestive of nonhemorrhagic pituitary apoplexy. Electrocardiogram (ECG) revealed T-wave inversion and extended QT interval. Transthoracic echocardiogram (TTE) showed left ventricular apical dysplasia and ballooning, accompanied by reduced left ventricular ejection fraction. Coronary angiography (CAG) revealed no obvious coronary arterial stenosis. The left ventriculogram demonstrated an octopus clathrate appearance. Most ECG and TTE changes recovered 10 days later.

Conclusions

To the best of our knowledge, this is the first report of newly diagnosed TTC associated with pituitary apoplexy.

Acute Cardiac Failure Due to Takotsubo Cardiomyopathy Secondary to a Phone Call for Lung Transplantation: A Case Report

Lung transplantation is a therapeutic option for certain end-stage lung diseases. The phone call for lung transplantation is a major event in the life of these patients; as a result, it can generate significant stress. We herein present the case of a 58-year-old female patient with end-stage chronic obstructive pulmonary disease (COPD) who, while on the lung transplantation waiting list, received such a call. Complete transplant work-up, including cardiac tests undertaken shortly before, had revealed no contraindication to lung transplantation. She was admitted with severe acute respiratory failure, and her extensive work-up was compatible with pulmonary edema due to takotsubo cardiomyopathy. The lung transplantation was thus cancelled, owing to the patient's health condition and the poor quality of the graft as well. The patient stayed in the intensive care unit for several days, requiring noninvasive ventilation. The left ventricular function recovered completely within 10 days postdiagnosis, and the patient was discharged 13 days after her admission. The patient was transplanted 1 month thereafter, without any particular problems; she is currently, 8 months post-transplantation, in good condition. In the given case, the call for lung transplantation could have generated emotional stress severe enough to lead to takotsubo cardiomyopathy.

Utility of recognizing early electrocardiogram changes in bronchogenic Takotsubo cardiomyopathy: A case report

BACKGROUND

Takotsubo cardiomyopathy (TCM) is a transient reversible systolic dysfunction, estimated to be the culprit in 1%-2% of patients presenting with clinical symptoms of acute coronary syndrome (ACS). TCM was previously thought to be indistinguishable from ACS on the basis of electrocardiogram (EKG) findings; many authors now describe specific EKG changes that distinguish TCM from ACS as well as aid in early recognition of TCM.

CASE SUMMARY

This unique case presentation illustrates an uncommon subtype of TCM, and very clearly exemplifies the specific EKG changes meant to aid in distinguishing TCM from ACS. A bronchogenic subtype of TCM has been proposed, given its prevalence and distinguishing features from TCM without pulmonary pathology; this case exemplifies that notion. The specific EKG changes of low QRS voltage and attenuation of the amplitude of the QRS complex are now being noted in the EKGs of TCM patients. This patient presented for worsening shortness of breath and increased productive cough; her EKG revealed ST elevations in leads V3-V6, and low voltage QRS complexes when compared to previous EKG from 12 wk ago; troponin peaked at 5.16 ng/mL. Left heart catheterization did not reveal significant lesions and left ventriculogram findings were consistent with TCM. Patient was treated for COPD exacerbation, her symptoms improved significantly; she was sent home on the appropriate medications.

CONCLUSION

This case exemplifies EKG changes noted in TCM patients who may aid in early detection and appropriate treatment of TCM.

Frequently Recurrent Takotsubo Syndrome in COPD

Cardiovascular disease is common among patients with chronic obstructive pulmonary disease (COPD). Takotsubo syndrome (TTS) is a transient cardiac disorder that, in its typical form, involves left ventricular dysfunction with apical ballooning and mimics acute coronary syndrome (ACS). “Bronchogenic TTS” has been proposed as a specific form of TTS (during severe acute dyspnea in asthma or COPD) with atypical presentation. Recurrent TTS in COPD seems to be exceptionally rare since only a handful of clinical cases have previously been reported in the literature. Here, we present a unique case of a frequently recurrent TTS during COPD exacerbation in a 70-year-old woman, with at least 4 different episodes of TTS within 5 years. This case report exemplifies the difficulties of the diagnosis of TTS at the onset of acute COPD exacerbation. Potential pathophysiological mechanisms and therapeutic strategies are also briefly discussed.

Takotsubo syndrome and dialysis: an uncommon association?

This review was performed to investigate the association between treatment with dialysis and Takotsubo syndrome in patients with end-stage renal disease. We systematically explored the PubMed database using the search terms "Takotsubo cardiomyopathy" and/or "stress-induced cardiomyopathy" and/or "Takotsubo syndrome" in combination with "dialysis" and "uremia." Of 3630 articles found, 8 articles reporting 10 cases were selected for analysis. Most patients were women, and their age ranged from 51 to 84 years. Diabetes mellitus and hypertension were diagnosed in 40% of patients, and glomerular disease was diagnosed in 30%. One only patient was treated with peritoneal dialysis; all others were treated with hemodialysis. The outcome was unfavorable in only one patient. An association between Takotsubo syndrome and dialysis is uncommon, but not negligible, and comorbidities play a major role in determining the clinical outcome.

An uncommon cause for grade 3 primary graft dysfunction after lung transplantation: Takotsubo cardiomyopathy

Takotusubo cardiomyopathy is an acute, temporary cardiac syndrome which is important for the differential diagnosis of dynamic electrocardiography alterations. Takotsubo cardiomyopathy related to lung transplantation is rather rare in the literature with only two case reports. Our case is the first Takotsubo cardiomyopathy case that manifested in the early period after lung transplantation. In this article, we present a 61-yearold male patient who was performed bilateral sequential lung transplantation for chronic obstructive pulmonary disease. During follow-up, Takotsubo cardiomyopathy was diagnosed, primary graft dysfunction related to cardiomyopathy was observed, and extracorporeal membrane oxygenation was required.

Recurrent Stress Cardiomyopathy During COPD Exacerbation: Are Beta-adrenergic Agonists Only to Blame?

Takotsubo cardiomyopathy (TCM) is a variant of stress-induced cardiomyopathy, characterized by transient left ventricular dysfunction that may be associated with emotional or physical triggers. We present the case of a 51-year-old Caucasian female with severe chronic obstructive pulmonary disease (COPD) who presented with syncope and was found to have her second lifetime episode of stress-induced cardiomyopathy. Eight months prior, she had been admitted with a COPD exacerbation and was found to have left ventricular (LV) dysfunction with ejection fraction (EF) of 22% attributed to TCM with subsequent normalization of her left ventricular function. Recurrence of stress-induced cardiomyopathy associated with COPD is a rare phenomenon and its presentation raises the possibility of a common underlying mechanism.

Takotsubo cardiomyopathy: A known unknown foe of asthma

INTRODUCTION

Patients with uncontrolled asthma are at a greater risk of asthma attacks requiring emergency room visits or hospital admissions. Takotsubo cardiomyopathy is potentially a significant complication in a course of status asthmaticus.

CASE STUDY

We describe a 43-year-old female patient who presented with status asthmaticus that was further complicated with takotsubo cardiomyopathy.

RESULTS

Recognizing apical ballooning syndrome is challenging in patients with a history of respiratory disease because the symptoms of the last entity may complicate the diagnostic approach. It is difficult to distinguish clinically apical ballooning syndrome from the acute airway exacerbation itself. Both asthma and takotsubo cardiomyopathy share the same clinical presentation with dyspnea and chest tightness. In our patient, the electrocardiographic abnormalities, the rapidly reversible distinctive characteristics of echocardiography, and the modest elevation of serum cardiac biomarkers levels, in combination with the presence of a stress trigger (severe asthma attack), strongly supported the diagnosis of broken heart syndrome.

CONCLUSIONS

Clinicians should re-evaluate asthma management and be aware of the complications associated with asthma attacks such as stress-induced cardiomyopathy.

Takotsubo cardiomyopathy with use of salbutamol nebulisation and aminophylline infusion in a patient with acute asthma exacerbation

Takotsubo cardiomyopathy, apical ballooning syndrome or stress-induced cardiomyopathy is characterised by transient left ventricular dysfunction, mimicking myocardial infarction in the absence of obstructive coronary artery disease or acute plaque rupture on coronary angiography. The exact mechanism of myocardial dysfunction in Takotsubo cardiomyopathy is unknown; however, due to its association with physical and emotional stress, it is postulated that catecholamines play a central role in its pathogenesis. We present a case of a patient who was admitted with acute asthma exacerbation and was treated with β-2 agonist nebulisation and intravenous aminophylline. During her hospital stay she developed Takotsubo cardiomyopathy.

Stress Cardiomyopathy in the Setting of COPD Exacerbation

Introduction. Stress cardiomyopathy, or takotsubo cardiomyopathy, is an acute, reversible left ventricular dysfunction usually initiated by a psychological or physical stress. We report this case of stress cardiomyopathy following a chronic obstructive pulmonary disease exacerbation and the subsequent treatment. Case Description. A 49-year-old white female with a history of chronic obstructive pulmonary disease presented to the emergency room via emergency medical services with worsening severe shortness of breath and productive cough for 2 weeks but denied any chest pain on arrival. On presentation, she was noted to be tachypneic, using her accessory muscles and with bilateral coarse expiratory wheezing on lung auscultation. Initial electrocardiogram demonstrated sinus tachycardia. She was treated with multiple albuterol treatments. Soon afterwards, the course was complicated by hypoxic respiratory failure eventually requiring intubation. Her repeat electrocardiogram showed acute changes consistent with myocardial infarction, and an echocardiograph demonstrated apical akinesia with an ejection fraction of 25% to 30%. The patient was urgently taken for cardiac catheterization, which showed no angiographic evidence of coronary artery disease. Three days after initial presentation, a repeat transthoracic echocardiogram showed overall left ventricular systolic function improvement. Discussion. This case provided a unique look at the difficulty of balancing catecholamines in a patient with bronchospasm and stress cardiomyopathy.
