Repeat recurrence of takotsubo cardiomyopathy related to inhaled beta-2-adrenoceptor agonists

Takotsubo cardiomyopathy following envenomation: An updated review

BACKGROUND

Takotsubo cardiomyopathy (TTC) can be diagnosed in patients presenting with clinical features of acute coronary syndrome (ACS) by using Mayo clinic criteria. Multiple precipitators have been attributed to causing TTC. Rarely it has been reported to occur following an acute envenomation.

AIM

This review describes the various patterns, mechanisms, and outcomes of envenomation induced TTC.

METHODS

In this review, we included all studies on “TTC” and “envenomation “published in the various databases before June 2022. To be included in the review articles had to have a distinct diagnosis of TTC and an envenomation

RESULTS

A total of 20 patients with envenomation induced TTC were identified. Most episodes of envenomation induced TTC were reported following a bee sting, scorpion sting, and snake envenomation. Fear and anxiety related to the sting, direct catecholamine toxicity and administration of exogenous beta-adrenergic agents have been commonly postulated to precipitate TTC in these patients. 95% of these patients presented with a clinical picture of ACS. Most of these patients also fulfill at least 3 out of 4 criteria of Mayo clinic criteria for TTC. Echocardiographic evidence of Apical TTC was noted in 72% of patients. 94% of these patients had clinical improvement following optimal management and 35% of these patients were treated with guideline directed medications for heart failure.

CONCLUSION

Envenomation following multiple insect stings and reptile bites can precipitate TTC. Most reported envenomation related TTC has been due to bee stings and scorpion bites. Common mechanisms causing TTC were fear, anxiety, and stress of envenomation. Most of these patients present with clinical presentation of ACS, ST elevation, and elevated troponin. The most common type of TTC in these patients is Apical, which improved following medical management.

A case report of recurrent takotsubo cardiomyopathy including the rare ‘inverted’ form

Background

Takotsubo cardiomyopathy (TC) is a disease that causes transient left ventricular (LV) dysfunction in multiple vascular territories in the absence of coronary artery disease. Takotsubo cardiomyopathy is typically associated with dilation and dyskinesia of the apical and mid-LV segments induced by acute emotional and/or physical stress. Here, we present a case of recurrent TC including one episode of inverted TC, which is a rare form where dyskinesia occurs in the basal segments with sparing of the apical segments.

Case summary

A 53-year-old female patient with a background history of chronic stress and anxiety was admitted with three episodes of recurrent TC over 4 years. The first episode in 2017 was triggered by an acute stressful event, but no major triggers were identified for the subsequent episodes. Although the first and third episodes displayed the signs of classical TC, the second episode was an inverted TC. Full cardiac function was restored after each episode. She now takes prognostic heart failure medications long term and mental health teams are trying to support her emotional wellbeing.

Discussion

This patient displayed a rare disease course involving three recurrent episodes of TC, including one instance of its inverted form. Although psychiatric conditions and emotional stress are acknowledged as risk factors for TC, further research is needed to assess whether mental health treatment following TC can prevent disease recurrence.

Takotsubo cardiomyopathy in a bedridden patient with dementia and communication difficulties due to Alzheimer’s disease

Takotsubo cardiomyopathy is a transient wall motion abnormality of the left ventricular apex, accompanied by emotional or physical stress. Although Takotsubo cardiomyopathy is generally considered a benign disease, severe clinical complications may occur, and early detection of the disease is important. In this report, we present the case of an 86-year-old bedridden woman with a history of bronchial asthma who was transferred to our hospital because of wheezing. She was diagnosed with Alzheimer’s disease and had communication difficulties. After an asthma attack and improvement, Takotsubo cardiomyopathy was identified via electrocardiography. She was unable to complain of any symptoms but showed serial electrocardiographic changes, elevated myocardial markers, and transient left ventricular apical ballooning. The prevalence of dementia increases dramatically with age. This case indicates that Takotsubo cardiomyopathy may occur even in patients with severe dementia, who are bedridden and show communication difficulties in a clinical setting.

Left Ventricular Ballooning Patterns in Recurrent Takotsubo Cardiomyopathy: A Systematic Review and Meta-analysis of Reported Cases

Recurrent takotsubo cardiomyopathy (TTC) and the clinical profiles and outcomes of patients have not been fully evaluated, nor has the effect of left ventricular ballooning pattern. After searching the medical literature for reports of patients with recurrent TTC, we identified 84 articles with 101 case descriptions. We divided the cases into those with only apical left ventricular ballooning patterns at recurrence (typical, n=60), and those with at least one midventricular or basal ballooning pattern (atypical, n=41). We then compared their clinical profiles and outcomes. The groups were similar in terms of baseline demographic characteristics, presence and types of triggers, use of heart failure medications at TTC recurrence, electrocardiographic changes at presentation, initial left ventricular ejection fractions, timespans between recurrent TTC episodes, and recovery times after each event. However, patients in the atypical group had significantly fewer severe adverse events (cardiogenic shock and cardiac arrest) than did those in the typical group, with an estimated 63% lower odds (adjusted odds ratio=0.37; 95% CI, 0.14-0.97; P=0.039). Survival to hospital discharge was statistically similar but lower in the typical group (n=53; 88.3%) than in the atypical group (n=24; 96%). Our results suggest that left ventricular ballooning patterns influence clinical outcomes, and that outcomes are more favorable in patients with recurrent TTC who have atypical left ventricular ballooning patterns.

Stress cardiomyopathy (Takotsubo syndrome) in patients who received adrenergic agonist drugs: A pharmacovigilance study using the Japanese Adverse Drug Event Report (JADER) database

INTRODUCTION

Stress cardiomyopathy, or Takotsubo syndrome (TTS), is an acute and reversible syndrome developing in strong association with psychological or physiological stressors. While a surge in the circulating catecholamine level is suspected as one of its pathophysiologies, the contribution of treatment with sympathomimetic drugs to the development of TTS remains uncertain.

METHODS

We conducted a disproportionality analysis using the Japanese Adverse Drug Event Report (JADER) database containing more than 500,000 patient cases recorded between April 2004 and March 2019, to detect TTS ('stress cardiomyopathy') as adverse event signals associated with adrenergic agonist drugs usage by calculating reporting odds ratio (ROR).

RESULTS

Among 306 TTS cases reported to JADER, we identified 58 TTS cases with exposure to adrenergic agonist drugs, predominantly of women (52/58, 89.7%) and those in the median age-decades of the 70s. After adjusting for age in decades and sex, most of the intravenous catecholamines showed significantly higher reporting (lower 95% ROR > 1) for TTS, including adrenaline, noradrenaline, dobutamine, dopamine, phenylephrine, and ephedrine. In addition, peroral midodrine, transdermal tulobuterol, inhaled salbutamol, and inhaled procaterol also showed significantly higher ROR for TTS. We also identified a small number of TTS cases with Parkinson's disease taking midodrine or droxidopa, but not receiving other adrenergic agonists.

CONCLUSION

The current pharmacovigilance study showed significantly higher RORs for TTS following the use of some of the adrenergic drugs, being mostly consistent with the TTS-related adrenergic drugs reported in earlier literature. A potential association of taking midodrine or droxidopa with the development of TTS was also suggested.

Ventricular arrhythmias in Takotsubo Syndrome: incidence, predictors and clinical outcomes

AIMS

To investigate predictors of the occurrence of subacute ventricular arrhythmias (VAs), defined as any VAs presenting after 48 h from admission in patients with Takotsubo Syndrome (TTS), and to evaluate the related in-hospital mortality.

METHODS

This is a retrospective single-center study enrolling patients admitted between 2012 and 2017 with TTS according to International Takotsubo diagnostic criteria. Data collection included ECG on admission and at 48 h, telemetry monitoring and transthoracic echocardiogram.

RESULTS

We enrolled 93 patients; during in-hospital stay (mean 14 ± 16 days) subacute VAs occurred in 25% of patients (VAs group). Life-threatening VAs occurred in 6% of patients (3 sustained ventricular tachycardia, 1 torsade de pointes, 1 ventricular fibrillation) and not life-threatening VAs in 19% (6 non-sustained ventricular tachycardia and 12 premature ventricular contractions > 2000 in 24 h). Mortality was higher in the VAs than in the non-VAs group (P = 0.03), without differences in terms of life-threatening and not life-threatening subacute VAs (P = 0.65) and VAs on admission (P = 0.25). Logistic regression identified the following independent predictors of subacute VAs occurrence: VAs on admission {odds ratio [OR] 22.5 (3.9-131.8), P = 0.001]}, New York Heart Association (NYHA) class III-IV on admission [OR 6.7 (1.3- 34.0), P = 0.021] and QTc at 48 h [OR 1.01 (1.00-1.03), P = 0.046].

CONCLUSION

TTS patients with VAs and NYHA class III-IV on admission and higher QTc at 48 h are at increased risk of subacute VAs occurrence, associated with higher in-hospital mortality. Awareness of this potential complication is critical for proper patients management.

International Expert Consensus Document on Takotsubo Syndrome (Part I): Clinical Characteristics, Diagnostic Criteria, and Pathophysiology

Takotsubo syndrome (TTS) is a poorly recognized heart disease that was initially regarded as a benign condition. Recently, it has been shown that TTS may be associated with severe clinical complications including death and that its prevalence is probably underestimated. Since current guidelines on TTS are lacking, it appears timely and important to provide an expert consensus statement on TTS. The clinical expert consensus document part I summarizes the current state of knowledge on clinical presentation and characteristics of TTS and agrees on controversies surrounding TTS such as nomenclature, different TTS types, role of coronary artery disease, and etiology. This consensus also proposes new diagnostic criteria based on current knowledge to improve diagnostic accuracy.

Forme Fruste in Recurring Mid-Ventricular Variant of Takotsubo Cardiomyopathy

BACKGROUND Takotsubo cardiomyopathy (TC) is characterized as acute left ventricular dysfunction precipitated by intense emotional or physiological stress. The mid-ventricular variant of TC usually has akinesis, with or without ballooning of the mid-ventricular segment, and a hyperdynamic base and apex. Recurrence of the typical and atypical (reversed and mid-ventricular type) forms has been reported in only a very small number of cases. We report a forme fruste presentation of mid-ventricular variant of TC. CASE REPORT A 69-year-old woman with a prior history of stress-induced cardiomyopathy presented with complaint of moderate intensity, persistent, sub-sternal chest discomfort. She reported that her symptoms were similar to those she had during a previous hospitalization in 2015, and this time cited the death of her mother as an inciting stressor. No significant obstructive flow-limiting coronary artery disease was found on cardiac catheterization. However, the left ventriculogram was suggestive of mid-ventricular pattern of TC. Her first symptomatic episode of apparent TC did not reveal completion of the mid-ventricular pattern of the TC variant. The subsequent episode, during this hospitalization, manifested as a completed version of her initial apparent forme fruste of mid-ventricular variant of TC. CONCLUSIONS TC may present in a myriad of clinical forms that must be considered in the evaluation of patients with suspected acute coronary syndromes or cardiomyopathy. Treatment is mainly supportive, and recurrence rates range from 7.7% to 11.4%. To the best of our knowledge, this forme fruste presentation has not been previously reported in recurrent variants of TC.

Inverted Variant of Takotsubo Syndrome Caused by Inhaled Adrenergic Beta-2 agonists

Takotsubo syndrome (TS) is an acute and reversible clinical syndrome characterized by transient hypokinesis of the left ventricular (LV) apex. Variant forms of LV dysfunction have been reported, including inverted Takotsubo syndrome (ITS), which represents only 5% of cases and has previously been linked to excessive use of inhaled adrenergic beta-2 agonists. The authors describe the case of a 60-year-old female patient who was diagnosed with ITS after the excessive use of inhaled adrenergic beta-2 agonists. This case highlights an uncommon variant of this syndrome that may not be obvious and must be suspected in this particular context.

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.

Drug-Induced Takotsubo Cardiomyopathy

BACKGROUND

The most plausible hypothesis for takotsubo cardiomyopathy (TCM) is a catecholamine surge. Direct administration of catecholamines or medications causing catecholamine surge is frequently used in clinical practice.

METHODS

A Medline/PubMed database search was conducted for case reports or series of drug-induced TCM. All reported cases of drug-induced TCM were systemically identified and analyzed.

RESULTS

We identified 157 cases of drug-induced TCM. Fifty-seven (36.3%) cases were related to the administration of exogenous catecholamines. In 50 (31.9%) other cases, there was potential adrenergic effect. This included drugs with adrenergic vasoconstriction properties (3.2%), hyperadrenergic state due to alcohol or opioid withdrawal (7.7%), inhibitors of catecholamine reuptake (14.7%), anaphylactic reaction that is accompanied by catecholamine release (3.2%), and psychological or somatic stress coinciding with the administration of a drug that was thought to be the culprit (3.2%). Overall, 68.2% of these drug-induced TCM cases were catecholamine related. In 14 (8.9%) cases, the likely etiology of cardiomyopathy was chemotherapy-induced coronary vasospasm.

CONCLUSION

Our systematic review showed that over two-thirds of drug-induced TCM cases were due to direct or indirect catecholamine stimulation. The lowest effective dose and shortest duration of catecholamines should be utilized, and alternative therapies should be considered if feasible.

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 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.

Takotsubo Cardiomyopathy: A New Perspective in Asthma

Takotsubo cardiomyopathy (TCM) is an entity of reversible cardiomyopathy known for its association with physical or emotional stress and may mimic myocardial infarction. We report an exceedingly rare case of albuterol-induced TCM with moderate asthma exacerbation. An interesting association that may help in understanding the etiology of TCM in the asthmatic population. Although the prognosis of TCM is excellent, it is crucial to recognize beta agonists as a potential stressor.

Bronchogenic Stress Cardiomyopathy: A Case Series

Despite a growing awareness of stress (takotsubo) cardiomyopathy, the diversity in precipitants beyond emotional distress remains under-appreciated. Emerging data implicate a differential influence of precipitant type on the variable presentations of stress cardiomyopathy. We outline 5 cases of stress cardiomyopathy where the precipitant was an acute exacerbation of chronic obstructive pulmonary disease treated with high-dose bronchodilator therapy. In this setting, an atypical and insidious presentation of the stress cardiomyopathy was consistently observed that was difficult to distinguish from the acute airway exacerbation itself, with an absence of chest pain in particular. Scrutiny of published single-case reports reveals a similar atypical presentation; this supports the existence of a novel bronchogenic subgroup of stress cardiomyopathy. A key role of repeat ECG evaluation in distinguishing protracted but uncomplicated bronchospasm from bronchogenic stress cardiomyopathy is highlighted. Further data are now required to examine whether high-dose β-agonist therapy is implicated in this association.

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

AIM: To investigate the possible association between Tako-tsubo cardiomyopathy (TTC)-a reversible clinical condition mimicking an acute myocardial infarction characterized by multifactorial pathophysiologic mechanisms- and respiratory system diseases.

METHODS: We systematically searched PubMed and EMBASE medical information sources, to identify the different triggering causes, limiting our search to articles in English. The search keywords were: “tako-tsubo cardiomyopathy”, “takotsubo”, “takotsubo cardiomyopathy”, “broken heart syndrome”, “stress-induced cardiomyopathy”, “apical ballooning syndrome”, and “ampulla cardiomyopathy in combination with respiratory diseases, lung, pulmonary disease. For each kind of disease, we registered: author, year and country of study, patient sex, age, concurring situation, and outcome.

RESULTS: Out of a total of 1725 articles found, we selected 37 papers reporting a total of 38 patients. As expected, most patients were women (81.6%), mean age was 65 ± 10 years. Outcome was favorable in 100% of cases, and all the patients have been discharged uneventfully in a few days.

CONCLUSION: An association between respiratory diseases and TTC is likely to exist. Patients with severe respiratory diseases, due to the high dosages of β₂-agonists used or to the need of invasive procedures, are highly exposed to the risk of developing TTC.

Lack of efficacy of drug therapy in preventing takotsubo cardiomyopathy recurrence: a meta-analysis

BACKGROUND

Efficacy of chronic drug therapy in prevention of stress-induced cardiomyopathy recurrences is not well established. We therefore aimed to evaluate in this meta-analysis whether pharmacological treatment can effectively prevent takotsubo cardiomyopathy (TTC) recurrences, according to available studies.

HYPOTHESIS

There is no evidence for preventing TTC recurrence by drug therapy.

METHODS

After a PubMed search, we conducted a meta-analysis of available studies (clinical nonrandomized registries) on efficacy of drug therapy in preventing recurrence of TTC.

RESULTS

A total of 23 (4.5%) TTC recurrences occurred in the 511 patients included in the analysis. Seven studies on the effects of β-blockers on prevention of TTC recurrence were evaluated; the odds ratio (OR) was 0.44 and the 95% confidence interval (CI) was 0.15-1.31. In 5 studies on the effects of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, the OR was 0.42 and the 95% CI was 0.08-2.36; in 3 studies on statins, the OR was 0.74 and the 95% CI was 0.07-7.3; and in 4 studies on aspirin, the OR was 0.33 with a 95% CI of 0.05-2.17 (P value not significant in all cases).

CONCLUSIONS

A meta-analysis of the efficacy of different medications through the clinical TTC registries available showed no clinical evidence for a standard drug treatment in the chronic management of TTC. β-Blockers, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, statins, and aspirin do not seem to significantly reduce recurrences of TTC. Randomized, adequately powered studies are needed to further assess this issue.

A case of apical ballooning syndrome in a male with status asthmaticus; highlighting the role of B2 agonists in the pathophysiology of a reversible cardiomyopathy

Apical ballooning syndrome (ABS), also known as Takotsubo cardiomyopathy, was first reported by Dote and colleagues in Japanese literature in 1991 in a review of five cases. Case series have highlighted the association of severe psychological stressors as the major precipitating factors of this syndrome. Status Epilepticus and Sub-Arachnoid hemorrhage are also now established independent etiologies for this phenomenon in patients without coronary artery disease. We report a case of reversible apical ventricular dysfunction in a 50-year-old male presenting with status asthmaticus who quickly underwent intubation. Following this, he had ST elevations in precordial leads with mild cardiac enzyme leak. Subsequent cardiac catheterization revealed a left ventricular ejection fraction of 25–30% with apical aneurismal segment. No obstructive disease was observed. Three days later there was marked clinical improvement; the patient was extubated and repeat echocardiography revealed a remarkable return to normal ventricular size and systolic function. Our case demonstrates that excess use of beta-agonists may be a potential risk factor for ABS and raises the possibility of cathecholamine cardiotoxicity being mediated via beta-receptors. Furthermore, it also negates the propensity of apical ballooning so far reported only in women with respiratory distress without confounding emotional stressors.
