RESUMO

BACKGROUND: Takotsubo syndrome (TS) is a reversible cause of heart failure; however, a minority of patients can develop serious complications, including cardiac rupture (CR). OBJECTIVES: Analyze case reports of CR related to TS, detailing patient characteristics to uncover risk factors and prognosis for this severe complication. METHODS: We conducted a systematic search of MEDLINE and Embase databases to identify case reports of patients with TS complicated by CR, from inception to October 2023. RESULTS: We included 44 subjects (40 females; 4 males) with a median age of 75 (IQR 71-82) years, of White/Caucasian (61%) or East Asian/Japanese (39%) ethnicity. An emotional trigger was present in 15 (34%) subjects and an apical ballooning pattern was observed in all cases (100%). ST-segment elevation was reported in 39 (93%) of 42 cases, with the anterior myocardial segments (37 [88%]) being the most compromised, followed by lateral (26 [62%]) and inferior (14 [33%]) segments. The median time to cardiac rupture was 48 (5-120) hours since admission, with the left ventricular free wall (25 [57%]) being the most frequent site of perforation. Surgery was attempted in 16 (36%) cases, and 28 (64%) patients did not survive. CONCLUSIONS: CR related to TS is a rare complication associated with high mortality and affecting elderly females, specially from White/Caucasian or East Asian/Japanese descent, presenting with anterior or lateral ST-segment elevation, and an apical ballooning pattern. Although data is limited and additional prospective studies are needed, the awareness of this life-threatening complication is crucial to early identify high-risk patients. CONDENSED ABSTRACT: Cardiac rupture is a rare complication of Takotsubo syndrome. We conducted a systematic review of cases complicated by cardiac rupture, and we identified 44 subjects (40 females and 4 males) with a median age of 75 (IQR 71-82) years, of White/Caucasian (61%) or East Asian/Japanese (39%) ethnicity, all with an apical ballooning pattern (100%). The median time to cardiac rupture was 48 (5-120) hours since admission, with the left ventricular free wall (25 [57%]) being the most frequent site of perforation. Surgery treatment was attempted in 16 (36%) cases, and 28 (64%) patients did not survive.

RESUMO

Takotsubo cardiomyopathy (TTC) is characterized by transient myocardial dysfunction triggered by both negative and positive emotional experiences, known respectively as broken heart syndrome (BHS) and happy heart syndrome (HHS). Despite the scarcity of comparative analyses between HHS and BHS in the literature, our pooled analysis, incorporating two retrospective registry analyses of 1395 TTC patients (57 HHS and 1338 BHS), reveals that while BHS is more prevalent, both conditions exhibit similar clinical presentations and outcomes. Statistical analyses, utilizing binary random effects models, indicate that diabetes mellitus is less common in HHS patients and serves as a predictor for BHS. Furthermore, there are differences in cardiac imaging between the two groups; individuals with HHS have higher odds of experiencing midventricular ballooning, whereas those with BHS are more likely to have apical ballooning. These findings highlight the similarities in clinical features and outcomes between HHS and BHS, while also illustrating distinct imaging profiles. The study emphasizes the need for future prospective studies to delve deeper into the implications of these TTC subtypes, offering valuable insights into their comparative aspects and underlying mechanisms.

RESUMO

Takotsubo syndrome occurs predominantly in women and is usually preceded by acute emotional and/or physical stress. Patients commonly present with chest pain and/or dyspnea. Syncope or out-of-hospital cardiac arrest is a rare presentation. We report an unusual case of takotsubo syndrome in an elderly patient who presented with left facial droop, slurred speech, and syncopal episode. Initial presumed diagnosis was an ischemic stroke/transient ischemic attack. However, the patient was then treated for acute myocardial ischemia/infarction based on abnormal electrocardiogram, elevated cardiac troponin, and unremarkable neurological workup. Eventually diagnosed with takotsubo syndrome. Our case illustrates the importance of prompt identification particularly in the context of atypical presentation and further evaluation to rule out serious causes to mitigate related morbidity and mortality while simultaneously avoiding unnecessary investigations.

RESUMO

We herein report a 49-year-old woman who developed "happy heart syndrome" while watching a family theater performance. She was followed up with cardiac magnetic resonance imaging (CMR). The time course of the CMR findings was similar to that previously reported for Takotsubo cardiomyopathy (TTC), including the form of "broken heart syndrome." CMR findings for "happy heart syndrome" have not been sufficiently investigated. However, the CMR findings in this case suggest that "happy heart syndrome" and other conventional TTC including "broken heart syndrome" are clinically a single disease, at least from an imaging aspect.

RESUMO

The incidence of takotsubo stress cardiomyopathy (TSCM) in males is low compared with females. Gender-based differences in clinical outcomes of TSCM are not well characterized. The aim of this meta-analysis was to analyze whether gender-based differences are observed in TSCM clinical outcomes. A comprehensive literature search of PubMed, Embase, Cochrane Library database, and Web of Science was performed from inception to June 20, 2022, for studies comparing the clinical outcomes between male and female patients with TSCM. The primary outcome of interest was in-hospital all-cause mortality and cardiogenic shock. The secondary outcomes were cardiovascular mortality, receipt of mechanical ventilation, intra-aortic balloon pump, occurrence of ventricular arrhythmia, and left ventricular thrombus. A random-effects model was used to calculate the risk ratios (RR) and confidence intervals (CI). Heterogenicity was assessed using the Higgins I2 index. Twelve observational studies involving 51,213 patients (4,869 males and 46,344 females) were included in the meta-analysis. Male gender was associated with statistically significant higher in-hospital all-cause mortality compared with females in patients with TSCM (RR 2.17, 95% CI 1.77 to 2.67, p <0.001). The rate of cardiogenic shock was significantly higher in males with TSCM compared with females (RR 1.66, 95% CI 1.29 to 2.12, p <0.001). Our meta-analysis showed a difference in the clinical outcomes of TSCM between men and women. Male gender was associated with a two-fold greater in-hospital all-cause mortality risk compared with female gender. The higher mortality risk associated with male gender deserves further study, particularly whether it represents later recognition of the condition and disparities in treatments.

RESUMO

Takotsubo syndrome (TS) describes a transient type of dilated cardiomyopathy that mimics acute coronary syndrome (ACS) on initial presentation. Classic TS presents with marked dilation and ballooning of the left ventricular apex with hyperdynamic basal segments. The most frequent etiology is from emotional and stressful triggers; recently, evidence suggests neurologic and psychiatric involvement. There are increasing reports of TS occurring secondary to migraine abortives. We describe a unique case of TS in a woman after taking sumatriptan to abort her headache.

RESUMO

Background: Recent studies suggested a relationship between Takotsubo syndrome (TTS) and malignancy. However, clinical outcomes of TTS associated with cancer have not been assessed completely. This study was aimed to investigate the outcomes of patients with TTS and cancer. Methods: We performed a systematic review and meta-analysis to evaluate the clinical outcomes of TTS in patients with and without malignancy. We systematically reviewed and analyzed 14 studies (189,210 patients) published in PubMed and Cochrane Library databases until December 2022. The primary outcome was all-cause mortality at the longest follow-up. Results: The prevalence of current or previous malignancy in patients with TTS was 8.7% (16,461 patients). Patients with TTS and malignancy demonstrated a higher risk of mortality at the longest follow-up than those with TTS alone (odds ratio [OR], 2.41; 95% confidence interval [CI]; 1.95-2.98; P < 0.001). Moreover, cancer was significantly associated with an increased risk of in-hospital or 30-day mortality (OR 2.36; 95% CI, 1.67-3.33; P < 0.001), shock (OR 1.42; 95% CI, 1.30-1.55; P < 0.001), mechanical respiratory support (OR 1.68; 95% CI, 1.59-1.77; P < 0.001), arrhythmia (OR 1.27; 95% CI, 1.21-1.34; P < 0.001), and major adverse cardiac events (OR 1.69; 95% CI, 1.18-2.442; P < 0.001). Conclusions: This study revealed significant associations between previous or active cancer and an increased risk of all-cause mortality and in-hospital adverse events in patients with TTS.

RESUMO

BACKGROUND: Takotsubo cardiomyopathy (TC) is a transient cardiac syndrome that manifests with symptoms resembling acute myocardial infarction (MI). It is characterized by temporary wall-motion abnormalities predominantly affecting the apical and mid-portions of the left ventricle, despite the absence of significant obstructive coronary disease. TC poses diagnostic challenges due to its resemblance to ST-segment elevation myocardial infarction. Our study aimed to determine the prevalence of TC and identify the factors associated with its occurrence in patients presenting with acute MI in Palestine. RESULTS: A retrospective analysis was conducted on a cohort of patients diagnosed with TC at Al-Makassed hospital. Women accounted for 90.7% of TC cases (95% CI 88.2-93.2%). The mean age of affected individuals ranged from 62 to 76 years. The most common presenting symptoms were chest pain (83.4%, 95% CI 80.0-86.7%) and dyspnea (20.4%, 95% CI 16.3-24.5%), often following an emotionally or physically stressful event. Electrocardiography (ECG) on admission indicated ST-segment elevations in 71.1% of cases (95% CI 67.2-75.1%), accompanied by mild elevations of Troponins in 85.0% of cases (95% CI 80.8-89.1%). Despite the initial severity, left ventricular ejection fraction (LVEF) improved from 20-49.9 to 59-76% within a mean time of 7-37 days. The in-hospital mortality rate was 1.7% (95% CI 0.5-2.8%), with complete recovery observed in 95.9% of cases (95% CI 93.8-98.1%) and rare recurrence. The underlying etiology is believed to involve exaggerated sympathetic stimulation. CONCLUSIONS: TC should be considered as a significant differential diagnosis in acute coronary syndrome (ACS) cases, particularly among postmenopausal women with a preceding stressful event. Our study provides insights into the prevalence and characteristics of TC in the Palestinian population. While stress has been recognized as a potential trigger for TC, further research is needed to explore if there are specific associations between occupation and other unique stressors in the Palestinian context and the prevalence of TC. The study's results can raise awareness among healthcare professionals in Palestine about the prevalence and characteristics of TC in their patient population.

RESUMO

Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy or "broken heart syndrome," is a reversible cardiac disorder characterized by left ventricular dysfunction without significant obstructive coronary artery disease. It is classically secondary to emotional stress in postmenopausal women but can also be secondary to physical stress. This report presents a unique case of takotsubo cardiomyopathy induced by intracranial hemorrhage in an 80-year-old female who presented with syncope.

RESUMO

Background Takotsubo syndrome is usually triggered by a stressful event. The type of trigger seems to influence the outcome and should therefore be considered separately. Methods and Results Patients included in the GEIST (German-Italian-Spanish Takotsubo) registry were categorized according to physical trigger (PT), emotional trigger (ET), and no trigger (NT) of Takotsubo syndrome. Clinical characteristics as well as outcome predictors were analyzed. Overall, 2482 patients were included. ET was detected in 910 patients (36.7%), PT in 885 patients (34.4%), and NT was observed in 717 patients (28.9%). Compared with patients with PT or NT, patients with ET were younger, less frequently men, and had a lower prevalence of comorbidities. Adverse in-hospital events (NT: 18.8% versus PT: 27.1% versus ET: 12.1%, P<0.001) and long-term mortality rates (NT: 14.4% versus PT: 21.6% versus ET: 8.5%, P<0.001) were significantly lower in patients with ET. Increasing age (P<0.001), male sex (P=0.007), diabetes (P<0.001), malignancy (P=0.002), and a neurological disorder (P<0.001) were associated with a higher risk of long-term mortality, while chest pain (P=0.035) and treatment with angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (P=0.027) were confirmed as independent predictors for a lower risk of long-term mortality. Conclusions Patients with ET have better clinical conditions and a lower mortality rate. Increasing age, male sex, malignancy, a neurological disorder, chest pain, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, and diabetes were confirmed as predictors of long-term mortality.

RESUMO

Cardiotoxicity caused by adrenergic receptor agonists overdosing or stress-induced catecholamine release promotes cardiomyopathy, resembling Takotsubo cardiomyopathy (TC). TC is characterized by transient regional systolic dysfunction of the left ventricle. The animal models of TC and modalities for assessing regional wall motion abnormalities in animal models are lacking. We previously reported the protective role of a small noncoding microRNA-204-5p (miR-204) in cardiomyopathies, but its role in TC remains unknown. Here we compared the impact of miR-204 absence on phenylephrine (PE)-induced and transaortic constriction (TAC)-induced changes in cardiac muscle motion in the posterior and anterior apical, mid, and basal segments of the left ventricle using 2-dimensional speckle-tracking echocardiography (2-STE). Wildtype and miR-204-/- mice were subjected to cardiac stress in the form of PE for four weeks or TAC-induced pressure overload for five weeks. PE treatment increased longitudinal and radial motion in the apex of the left ventricle and shortened the peak motion time of all left ventricle segments. The TAC led to decreased longitudinal and radial motion in the left ventricle segments, and there was no difference in the peak motion time. Compared to wildtype mice, PE-induced peak cardiac muscle motion time in the anterior base of the left ventricle was significantly earlier in the miR-204-/- mice. There was no difference in TAC-induced peak cardiac muscle motion time between wildtype and miR-204-/- mice. Our findings demonstrate that PE and TAC induce regional wall motion abnormalities that 2-STE can detect. It also highlights the role of miR-204 in regulating cardiac muscle motion during catecholamine-induced cardiotoxicity.

RESUMO

BACKGROUND: Hypoalbuminemia is common in critically ill patients and is associated with poor outcomes. However, the relationship between serum albumin levels and clinical outcomes in patients with takotsubo syndrome remains unclear. We examined the impact of hypoalbuminemia on in-hospital mortality in patients with takotsubo syndrome. METHODS: Using the multicenter registry of the Tokyo Cardiovascular Care Unit Network between January 2017 and December 2020, we identified 631 eligible patients with takotsubo syndrome (median age, 78 years; male proportion, 22 %) and documented serum albumin levels at admission, which were used to allocate patients to hypoalbuminemia (serum albumin <3.5 g/dL) or normal albumin (serum albumin ≥3.5 g/dL) groups. Patient characteristics and in-hospital mortality were compared between the groups. RESULTS: Hypoalbuminemia was detected in 200 (32 %) patients at admission. The hypoalbuminemia group was older and had a higher proportion of men and preceding physical triggers than the normal albumin group. In-hospital all-cause mortality was greater in the hypoalbuminemia group than in the normal albumin group (9.5 % vs. 1.9 %, p < 0.001). Both cardiac (3.0 % vs. 0.5 %, p = 0.015) and non-cardiac (6.5 % vs. 1.4 %, p = 0.002) mortality was greater in the hypoalbuminemia group. In multivariable logistic regression analysis, hypoalbuminemia was independently associated with increased in-hospital mortality, even after adjusting for confounders, including age, sex, and triggering events (odds ratio, 3.23; 95 % confidence interval, 1.31-7.95; p = 0.011). CONCLUSIONS: In patients with takotsubo syndrome, hypoalbuminemia is a common comorbidity and is associated with a substantial risk of in-hospital death. Close monitoring and comprehensive critical care are required in these patients.

RESUMO

BACKGROUND AND AIMS: Takotsubo syndrome (TTS) is a conundrum without consensus about the cause. In a murine model of coronary microvascular dysfunction (CMD), abnormalities in myocardial perfusion played a key role in the development of TTS. METHODS AND RESULTS: Vascular Kv1.5 channels connect coronary blood flow to myocardial metabolism and their deletion mimics the phenotype of CMD. To determine if TTS is related to CMD, wild-type (WT), Kv1.5-/-, and TgKv1.5-/- (Kv1.5-/- with smooth muscle-specific expression Kv1.5 channels) mice were studied following transaortic constriction (TAC). Measurements of left ventricular (LV) fractional shortening (FS) in base and apex, and myocardial blood flow (MBF) were completed with standard and contrast echocardiography. Ribonucleic Acid deep sequencing was performed on LV apex and base from WT and Kv1.5-/- (control and TAC). Changes in gene expression were confirmed by real-time-polymerase chain reaction. MBF was increased with chromonar or by smooth muscle expression of Kv1.5 channels in the TgKv1.5-/-. TAC-induced systolic apical ballooning in Kv1.5-/-, shown as negative FS (P < 0.05 vs. base), which was not observed in WT, Kv1.5-/- with chromonar, or TgKv1.5-/-. Following TAC in Kv1.5-/-, MBF was lower in LV apex than in base. Increasing MBF with either chromonar or in TgKv1.5-/- normalized perfusion and function between LV apex and base (P = NS). Some genetic changes during TTS were reversed by chromonar, suggesting these were independent of TAC and more related to TTS. CONCLUSION: Abnormalities in flow regulation between the LV apex and base cause TTS. When perfusion is normalized between the two regions, normal ventricular function is restored.

RESUMO

BACKGROUND: There are emerging reports of Takotsubo syndrome (TTS) in cancer patients treated with immune checkpoint inhibitors (ICIs); however, the association of the two remains uncertain. METHODS: A systematic literature review was performed in the PubMed database and web sources (Google Scholar) according to the Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) guidelines. Case reports/series or studies including cancer patients treated with ICIs and presenting with TTS were considered. RESULTS: Seventeen cases were included in the systematic review. Most patients were males (59%) with median age of 70 years (30-83). Most common tumor types were lung cancer (35%) and melanoma (29%). Most patients were on first-line immunotherapy (35%) and after the first cycle (54%) of treatment. The median time on immunotherapy at the time of TTS presentation was 77 days (1-450). The most used agents were pembrolizumab and the combination of nivolumab-ipilimumab (35%, respectively). Potential stressors were recognized in 12 cases (80%). Six patients (35%) presented with concurrent cardiac complications. Corticosteroids were used in the management of eight patients (50%). Fifteen patients (88%) recovered from TTS, two patients (12%) relapsed, and one patient died. Immunotherapy was reintroduced in five cases (50%). CONCLUSION: TTS may be associated with immunotherapy for cancer. Physicians should be alert for TTS diagnosis in any patient with myocardial infarction-like presentation under treatment with ICIs.

RESUMO

Takotsubo cardiomyopathy, also known as stress cardiomyopathy (SCM) or broken heart syndrome, is characterized by transient systolic dysfunction of the left ventricle (LV). It typically affects the apical segment, but several rare variants exist. This report represents a rare variant of atypical stress cardiomyopathy that mimics territorial regional wall motion abnormalities of a blocked epicardial vessel.

RESUMO

BACKGROUND: Takotsubo syndrome (TS) is a life-threatening acute heart failure syndrome without any evidence-based treatment options. No treatment for TS has been examined in a randomized trial. STUDY DESIGN AND OBJECTIVES: BROKEN-SWEDEHEART is a multicenter, randomized, open-label, registry-based 2 × 2 factorial clinical trial in patients with TS designed to test whether treatment with adenosine and dipyridamole accelerates cardiac recovery and improves clinical outcomes compared to standard care (study 1); and apixaban reduces the risk of thromboembolic events compared to no treatment with antithrombotic drugs (study 2). The trial will enroll 1,000 patients. Study 1 (adenosine hypothesis) will evaluate 2 coprimary end points: (1) wall motion score index at 48 to 96 hours (evaluated in the first 200 patients); and (2) the composite of death, cardiac arrest, need for mechanical assist device or heart failure hospitalization within 30 days or left ventricular ejection fraction <50% at 48 to 96 hours (evaluated in 1,000 patients). The primary end point in study 2 (apixaban hypothesis) is the composite of death or thromboembolic events within 30 days or the presence of intraventricular thrombus on echocardiography at 48 to 96 hours. CONCLUSIONS: BROKEN-SWEDEHEART will be the first prospective randomized multicenter trial in patients with TS. It is designed as 2 parallel studies to evaluate whether adenosine accelerates cardiac recovery and improves cardiac function in the acute phase and the efficacy of anticoagulation therapy for preventing thromboembolic complications in TS. If either of its component studies is successful, the trial will provide the first evidence-based treatment recommendation in TS. CLINICAL TRIALS IDENTIFIER: The trial has been approved by the Swedish Medicinal Product Agency and the Swedish Ethical Board and is registered at ClinicalTrials.gov (NCT04666454).

RESUMO

BACKGROUND: A rare presentation of pheochromocytoma (PCC) is catecholamine-induced-cardiomyopathy, or Takotsubo cardiomyopathy (TCM). PCC-induced TCM(PCC-TCM) can present as a typical or atypical type, based on the location of cardiac wall motion abnormalities. In this review, we sought to assess features and outcomes for PCC-TCM, and to compare typical and atypical subtypes. METHODS: A search was conducted on two databases (PubMed and Embase) for case series or reports on PCC-TCM from 2006 to 2020. RESULTS: One-hundred-and-two papers with a total of 104 cases of PCC-TCM were retrieved: 67(64.4%) typical and 37(35.6%) atypical subtypes. Overall median age was 50[range:23-86] years, the atypical group about a decade younger(p < 0.001). A female preponderance was seen for either subtype (∼75%). The most common presentations were chest pain(n = 60;58%), dyspnoea(n = 46;44%), and headache(n = 41;39.4%). Those with atypical subtype more often presented with fluid overload (typical:3% versus atypical:60%); acute pulmonary oedema (35% versus 60%); and cardiogenic shock (22% versus 43%) (all p < 0.05). Six patients (6%) died pre-operatively (typical:8% versus atypical:3%; p = 0.32). Non-fatal pre-operative complications occurred more among those with atypical TCM(p < 0.001), specifically cardiac arrest (typical:5% versus atypical:32%) and respiratory failure (9% versus 24%; both p < 0.05). Overall, 98 underwent surgery, majority undergoing laparoscopic adrenalectomy (81%); similar among the subtypes(p = 0.71). No robust data was provided on short-term outcomes, although two patients suffered from post-operative complications. CONCLUSION: Although quite similar in presentation to either standalone TCM or PCC, PCC-TCM seems to be associated with a higher degree of morbidity and mortality. The atypical PCC-TCM subgroup seems to have a more severe course with possibly a poorer outcome. Further research is needed to make more reliable inferences.

RESUMO

Background and Objective: Takotsubo syndrome (TTS) is a condition characterized by transient ventricular regional wall motion abnormalities, without causative coronary artery disease, typically triggered by emotional or physical stress. TTS is more common in post-menopausal women, closely resembling acute coronary syndrome (ACS) in its clinical presentation, with multiple proposed underlying pathophysiological mechanisms and no evidence-based treatments. This review aims to provide a comprehensive summary of the latest research, encompassing the pathophysiology, diagnostic findings, prognosis, and treatment options for TTS patients. Methods: Relevant literature from 1990 to June 2023 on TTS epidemiology, physiopathology, diagnosis, clinical manifestations, treatment, and prognosis was retrieved through PubMed research. Only English publications were included. Key Content and Findings: TTS is an increasingly recognized cardiovascular disorder, a significant release of catecholamines is thought to be a key contributing element, yet its exact mechanism remains unclear. Notably, TTS poses significant short and long-term risks akin to ACS. Initial treatment should focus on ruling out ACS and providing standard care for subsequent left ventricular dysfunction and complications. Research hints at a potential role for Angiotensin-converting enzyme inhibitors and Angiotensin II receptor blockers in improving long-term prognosis in TTS patients. Conclusions: Significant knowledge gaps still exist in our understanding of the pathophysiology, treatment options, and areas for improvement in diagnosing and prognosticating this intriguing condition. Further research is therefore needed.
