Cardiac arrest in takotsubo syndrome: results from the InterTAK Registry. Eur Heart J 2020; 40:2142-2151. [PMID: 31098611 PMCID: PMC6612368 DOI: 10.1093/eurheartj/ehz170] [Citation(s) in RCA: 66] [Impact Index Per Article: 16.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2018] [Revised: 09/11/2018] [Accepted: 03/12/2019] [Indexed: 12/27/2022] Open
Abstract
AIMS We aimed to evaluate the frequency, clinical features, and prognostic implications of cardiac arrest (CA) in takotsubo syndrome (TTS). METHODS AND RESULTS We reviewed the records of patients with CA and known heart rhythm from the International Takotsubo Registry. The main outcomes were 60-day and 5-year mortality. In addition, predictors of mortality and predictors of CA during the acute TTS phase were assessed. Of 2098 patients, 103 patients with CA and known heart rhythm during CA were included. Compared with patients without CA, CA patients were more likely to be younger, male, and have apical TTS, atrial fibrillation (AF), neurologic comorbidities, physical triggers, and longer corrected QT-interval and lower left ventricular ejection fraction on admission. In all, 57.1% of patients with CA at admission had ventricular fibrillation/tachycardia, while 73.7% of patients with CA in the acute phase had asystole/pulseless electrical activity. Patients with CA showed higher 60-day (40.3% vs. 4.0%, P < 0.001) and 5-year mortality (68.9% vs. 16.7%, P < 0.001) than patients without CA. T-wave inversion and intracranial haemorrhage were independently associated with higher 60-day mortality after CA, whereas female gender was associated with lower 60-day mortality. In the acute phase, CA occurred less frequently in females and more frequently in patients with AF, ST-segment elevation, and higher C-reactive protein on admission. CONCLUSIONS Cardiac arrest is relatively frequent in TTS and is associated with higher short- and long-term mortality. Clinical and electrocardiographic parameters independently predicted mortality after CA.

Long-Term Prognosis of Patients With Takotsubo Syndrome. J Am Coll Cardiol 2019; 72:874-882.

Abstract
BACKGROUND Prognosis of Takotsubo syndrome (TTS) remains controversial due to scarcity of available data. Additionally, the effect of the triggering factors remains elusive. OBJECTIVES This study compared prognosis between TTS and acute coronary syndrome (ACS) patients and investigated short- and long-term outcomes in TTS based on different triggers. METHODS Patients with TTS were enrolled from the International Takotsubo Registry. Long-term mortality of patients with TTS was compared to an age- and sex-matched cohort of patients with ACS. In addition, short- and long-term outcomes were compared between different groups according to triggering conditions. RESULTS Overall, TTS patients had a comparable long-term mortality risk with ACS patients. Of 1,613 TTS patients, an emotional trigger was detected in 485 patients (30%). Of 630 patients (39%) related to physical triggers, 98 patients (6%) had acute neurologic disorders, while in the other 532 patients (33%), physical activities, medical conditions, or procedures were the triggering conditions. The remaining 498 patients (31%) had no identifiable trigger. TTS patients related to physical stress showed higher mortality rates than ACS patients during long-term follow-up, whereas patients related to emotional stress had better outcomes compared with ACS patients. CONCLUSIONS Overall, TTS patients had long-term outcomes comparable to age- and sex-matched ACS patients. Also, we demonstrated that TTS can either be benign or a life-threating condition depending on the inciting stress factor. We propose a new classification based on triggers, which can serve as a clinical tool to predict short- and long-term outcomes of TTS.

Effect of locally tailored labour management guidelines on intrahospital stillbirths and birth asphyxia at the referral hospital of Zanzibar: a quasi-experimental pre-post study (The PartoMa study). BJOG 2017; 125:235-245.

Abstract
OBJECTIVE To evaluate effect of locally tailored labour management guidelines (PartoMa guidelines) on intrahospital stillbirths and birth asphyxia. DESIGN Quasi-experimental pre-post study investigating the causal pathway through changes in clinical practice. SETTING Tanzanian low-resource referral hospital, Mnazi Mmoja Hospital. POPULATION Facility deliveries during baseline (1 October 2014 until 31 January 2015) and the 9th to 12th intervention
month (1 October 2015 until 31 January 2016) [corrected]. METHODS Birth outcome was extracted from all cases of labouring women during baseline (n = 3690) and intervention months (n = 3087). Background characteristics and quality of care were assessed in quasi-randomly selected subgroups (n = 283 and n = 264, respectively). MAIN OUTCOME MEASURES Stillbirths and neonates with 5-minute Apgar score ≤5. RESULTS Stillbirth rate fell from 59 to 39 per 1000 total births (RR 0.66, 95% CI 0.53-0.82), and subanalyses suggest that this was primarily due to reduction in intrahospital stillbirths. Apgar scores between 1 and 5 fell from 52 to 28 per 1000 live births (RR 0.53, 95% CI 0.41-0.69). Median time from last fetal heart assessment till delivery (or fetal death diagnosis) fell from 120 minutes (IQR 60-240) to 74 minutes (IQR 30-130) (Mann-Whitney test for difference, P < 0.01). Oxytocin augmentation declined from 22% to 12% (RR 0.54, 95% CI 0.37-0.81) and timely use improved. CONCLUSION Although low human resources and substandard care remain major challenges, PartoMa guidelines were associated with improvements in care, leading to reductions in stillbirths and birth asphyxia. Findings furthermore emphasise the central role of improved fetal surveillance and restricted intrapartum oxytocin use in safety at birth. TWEETABLE ABSTRACT: #PartoMa guidelines aided in reducing stillbirths and birth asphyxia at a Tanzanian low-resource hospital PLAIN LANGUAGE SUMMARY: PartoMa guidelines help birth attendants in Tanzania to save lives Every year, 3 million babies die on the day of birth. The vast majority of these deaths occur in the poorest countries. If their mothers had received better care during birth, most babies would have survived. At Mnazi Mmoja Hospital, an East African referral hospital, the PartoMa study shows that use of locally developed guidelines helps birth attendants to deliver better quality of care, which has led to improved survival at birth. At the hospital studied, resources are scarce. Each birth attendant assists four to six birthing women simultaneously, and many have less than 1 year of professional experience. International guidelines are available, but they are often unachievable and seldom applied. The PartoMa guidelines were developed in close collaboration with the birth attendants and approved by seven international experts. The result is an 8-page pocket booklet providing locally achievable and simple decision support for care during birth. Use of the PartoMa guidelines began in February 2015. As the staff group frequently changes, quarterly seminars are conducted where birth attendants are welcomed after working hours to learn about the guidelines. The guidelines have been positively received, and seminar attendance remains high. Use of the PartoMa guidelines is associated with: A decrease by one-third in stillbirths (59 to 39 per 1000 total births) A nearly halving in the number of babies born in immediate poor medical condition (52 to 28 per 1000 live births) The results presented here derive from a comparison of births before using the PartoMa guidelines and during the 9th-12th month of use. Such a 'before-after' study cannot exclude the possibility of other causes of better survival at birth. However, the improved survival is consistent with improved care during birth, which is in line with the PartoMa guidelines.

Takotsubo Cardiomyopathy: What we have Learned in the Last 25 Years? (A Comparative Literature Review). Curr Cardiol Rev 2016; 12:297-303.

Abstract
We performed a comparative literature review, to elucidate the major features of the Takotsubo (stress) cardiomyopathy (TCM) collected in last 25 years. TCM is characterized by left- or biventricular apical ballooning with a clinical presentation, electrocardiographic abnormalities, and biomarker profils similar to those seen in acute myocardial infarction. Epidemiological studies have shown that TCM is more common in postmenopausal women; however exact figures are not available. The underlying aetiology is still largely undetermined. Elevated catecholamine levels, lack of estrogen, disturbed myocardial fatty acid metabolism and plaque rupture with spontaneous thrombolysis are potentially discussed mechanisms responsible for inducing a prolonged stunned myocardium. Strong emotional or physical stress is the most frequently described trigger in the literature. Therapy recommendations include appropriate antiplatelet treatment, β-blockers and ACE inhibitors. The abnormal kinetics usually resolve or improve within a month and carry a favorable prognosis in most cases. However, all the suspected complications of an acute myocardial infarction, including cardiogenic shock or lethal arrhythmias, may still occur.

Abstract
BACKGROUND The natural history, management, and outcome of takotsubo (stress) cardiomyopathy are incompletely understood. METHODS The International Takotsubo Registry, a consortium of 26 centers in Europe and the United States, was established to investigate clinical features, prognostic predictors, and outcome of takotsubo cardiomyopathy. Patients were compared with age- and sex-matched patients who had an acute coronary syndrome. RESULTS Of 1750 patients with takotsubo cardiomyopathy, 89.8% were women (mean age, 66.8 years). Emotional triggers were not as common as physical triggers (27.7% vs. 36.0%), and 28.5% of patients had no evident trigger. Among patients with takotsubo cardiomyopathy, as compared with an acute coronary syndrome, rates of neurologic or psychiatric disorders were higher (55.8% vs. 25.7%) and the mean left ventricular ejection fraction was markedly lower (40.7±11.2% vs. 51.5±12.3%) (P<0.001 for both comparisons). Rates of severe in-hospital complications including shock and death were similar in the two groups (P=0.93). Physical triggers, acute neurologic or psychiatric diseases, high troponin levels, and a low ejection fraction on admission were independent predictors for in-hospital complications. During long-term follow-up, the rate of major adverse cardiac and cerebrovascular events was 9.9% per patient-year, and the rate of death was 5.6% per patient-year. CONCLUSIONS Patients with takotsubo cardiomyopathy had a higher prevalence of neurologic or psychiatric disorders than did those with an acute coronary syndrome. This condition represents an acute heart failure syndrome with substantial morbidity and mortality. (Funded by the Mach-Gaensslen Foundation and others; ClinicalTrials.gov number, NCT01947621.).

Abstract
Dronedarone is a relatively new antiarrhythmic drug and is held to be less proarrhythmic than comparable compounds, although its proarrhythmia potential in humans has not been sufficiently evaluated. We describe a so far unreported dronedarone effect, namely a significant alteration of both the morphology and the duration of the QRS complex on the electro cardiogram in a 41-year old patient with symptomatic paroxysmal atrial fibrillation.

Abstract
OBJECTIVES Flail chest results in significant morbidity. Controversies continue regarding the optimal management of flail chest. No clear guidelines exist for surgical stabilization. Our aim was to examine the association of bedside spirometry values with operative stabilization of flail chest. METHODS IRB approval was obtained to identify patients with flail chest who underwent surgical stabilization between August 2009 and May 2011. At our institution, all rib fracture patients underwent routine measurement of their forced vital capacity (FVC) using bedside spirometry. Formal pulmonary function tests were also obtained postoperatively and at three months in patients undergoing stabilization. Both the Synthes and Acute Innovations plating systems were utilized. Data is presented as median (range) or (percentage). RESULTS Twenty patients (13 male: 65 %) with median age of 60 years (30-83) had a median of four ribs (2-9) in the flail segment. The median Injury Severity Score was 17 (9-41) and the median Trauma and Injury Severity Score was 0.96 (0.04-0.99). Preoperative pneumonia was identified in four patients (20 %) and intubation was required in seven (35 %). Median time from injury to stabilization was four days (1-33). The median number of plates inserted was five (3-11). Postoperative median FVC (1.8 L, range 1.3-4 L) improved significantly as compared to preoperative median value (1 L, range 0.5-2.1 L) (p = 0.003). This improvement continued during the follow-up period at three months (0.9 L, range 0.1-3.0) (p = 0.006). There were three deaths (15 %), none of which were related to the procedure. Subsequent tracheostomy was required in three patients (15 %). The mean hospital stay and ventilator days after stabilization were nine days and three days, respectively. Mean follow-up was 5.6 ± 4.6 months. CONCLUSION Operative stabilization of flail chest improved pulmonary function compared with preoperative results. This improvement was sustained at three months follow-up.

Abstract
Based on an analysis of the Magdeburg Dronedarone Registry data we sought to determine which patients could benefit from dronedarone therapy regarding rhythm control. The study included 191 patients (85 women) aged 63 ± 10 years with a history of paroxysmal or persistent AF and a follow-up of 14 ± 5 months. The total AF recurrence rate was 67% and lone AF was significantly more often associated with AF recurrences than non-lone AF (84% vs. 62%, P = .01). Arterial hypertension, treated coronary artery disease, and diabetes mellitus were not significantly related to AF recurrences (64%, 67%, 58% resp. P = .3). Response rate to dronedarone in patients with slightly increased left atrial size was significantly greater than in patients with normal or markedly increased left atrial size (47%, 16%, 27% resp., P = .001). The rate of adverse effects was 32% in the study sample, and was significantly lower in patients with lone AF as compared to those with non-lone AF (11% vs. 37%, P = .002). The body mass index was a predictor neither of response rate nor adverse effects. The results suggest that dronedarone is more effective in patients with non-lone AF and slightly increased left atrial size.

Abstract
BACKGROUND Dronedarone is a new antiarrhythmic agent that has only recently been approved for the therapy of atrial fibrillation (AF). Results regarding a broader spectrum of patients and experience accumulated in clinical practice are still very scarce. Therefore, we prospectively investigated the efficacy and tolerance of dronedarone in a real life setting. METHODS AND RESULTS The study included 191 patients (85 women) aged 63 ± 9.9 years with a history of paroxysmal or persistent AF. Follow-up time was 14.3 ± 4.9 months. In patients with persistent AF, sinus rhythm was restored using electrical cardioversion prior to dronedarone administration. Each patient underwent standard ECG on a daily basis during the first 4 days of treatment, and on days 7, 30 and 90, resp. After that, the patients had a follow-up visit every three months. Creatinine, creatine kinase, and hepatic enzymes were closely monitored. Clinical history was meticulously taken at multiple follow-up visits. Dronedarone maintained sinus rhythm in 33.5% (95% CI: 27%-40%), and AF recurrence rate was high: 66.5% (95% CI: 60%-73%). Adverse effects occurred in 31.9% (95% CI: 27%-38%) of the patients and necessitated permanent discontinuation of dronedarone in 22% (95% CI: 17%-27%). CONCLUSIONS The results suggest that dronedarone may not be superior to available antiarrhythmic agents and caution against its use as a first line therapy in AF.

Abstract
Thrombin injection is frequently used to occlude iatrogenic pseudoaneurysms in larger vessels, but has never successfully been used in the radial artery location. Here we report the use of this treatment in a patient with radial artery pseudoaneurysm following coronary intervention. After Doppler sonographic visualization of the pseudoaneurysm cavity and its neck, an ultrasound-guided transcutaneous injection of thrombin was carried out. Immediately after the injection, the pseudoaneurysm was completely clotted and Doppler measurement confirmed the stop of blood flow. The result suggests that ultrasound-guided injection of thrombin into a radial artery pseudoaneurysm following coronary intervention is a feasible alternative to surgical intervention.

Abstract
Thrombocytopenia in patients with percutanous coronary intervention is a known complication of glycoprotein IIb/IIIa inhibitors. This can limit the application of these agents. Platelet count monitoring 2, 6, 12 and 24 hours after starting the treatment reveals most cases of acute thrombocytopenia. Side effects can be avoided by the early discontinuation of the glycoprotein IIb/IIIa antagonist treatment. A selective diagnostic approach by laboratory measures should exclude any confusion with heparin-induced thrombocytopenia and pseudo thrombocytopenia.

Abstract
BACKGROUND Among the causes of death, cancer ranks second after cardiovascular diseases. If a cancer patient dies before the tumor is diagnosed the malignancy may be unreported among post-mortem findings and thus is often not included in cancer and cause of death statistics. METHOD All 8844 autopsies carried out at the Institute of Forensic Medicine for the City of Hamburg from 1994 to 2001 were analysed and those cases with malignant tumor identified. The cases were then included in the cancer registry if this had not been done previously. The postmortem diagnosis of malignancy was made histologically on formalin-fixed tissue. In these cases attempts were made to find out if the initial diagnosis of malignancy had been made before death. RESULTS A malignancy was found in 519 autopsies (5.9 %). In 67.3 % of these (349/519) the patients had been aware of the disease. 27.2 % of all malignant tumors (141/519) were discovered during the post-mortem examination. In 5.6 % of cases (29/519) the question of whether the tumor had been diagnosed before death could not be answered because of lack of data or an incomplete case history. In 52.2 % (271/519) of the autopsies the tumor had definitely been the cause of death. Of these 271 tumors 17 % (46/271) were discovered only during the forensic post-mortem examination. The Hamburg Cancer Registry had been notified of only 58 cases of the 519. As a result of this study 451 new cancer cases (86.9 %) were notified to the Hamburg cancer registry. CONCLUSIONS The registration of cancer deaths in Hamburg is incomplete and the notification of cancer to the Cancer Registry is inadequate. The estimated number of unreported cases is probably greater and cancer as the cause of death is higher than reported in the statistics.

Abstract
Thrombocyte glycoprotein IIb/IIIa inhibitors prevent fibrinogen binding and thereby thrombocyte aggregation. The inhibition of thrombocyte activation at the damaged coronary plaque is the target of the new therapeutic strategies in treating acute coronary syndrome. This reduces the ischemic complications associated with the non-STelevation myocardial infarction (NSTEMI) and percutaneous coronary intervention (PCI). Thrombocytopenia is a known complication of glycoprotein (GP) IIb/IIIa inhibitors. Although, in general, GP IIb/IIIa inhibitor-induced thrombocytopenia is a harmless side effect which responds readily to thrombocyte transfusion, it can occasionally be a very serious complication associated with serious bleeding. In addition patients developing thrombocytopenia have unfavorable outcome (e.g., death, myocardial infarction, bypass surgery or additional PCI) in comparison to patients without thrombocytopenia. Advanced age (> 65 years), low BMI and a low initial thrombocyte count (<180,000/microl) are independent risk factors of thrombocytopenia. The risk of bleeding is higher with this form of thrombocytopenia not only due to the low thrombocyte count but also to the impaired function of the remaining thrombocytes. It is important to closely monitor platelet count during GP IIb/IIIa antagonist treatment. Platelet count monitoring two, six, twelve and 24 hour after starting the treatment reveals most cases of acute thrombocytopenia. Side effects can be avoided by the early discontinuation of the GP IIb/IIIa antagonist treatment. This article reviews the diagnosis and treatment of glycoprotein IIb/IIIa inhibitor-induced thrombocytopenia and summarizes the differential diagnosis from heparin-induced thrombocytopenia and laboratory-related pseudothrombocytopenia.

Abstract
Volumes of cerebral gray and white matter were measured in 22 children with neurofibromatosis type 1 (NF1) and in 20 controls. Judgment of Line Orientation (JLO) and the Developmental Test of Visual-Motor Integration (DTVMI) were administered to 16 of the NF1 patients. General linear models analysis of covariance revealed significantly larger brain volumes in NF1 children than in controls, particularly in white matter, and particularly in girls. JLO and DTVMI performance were positively related to right-hemisphere gray-matter volume. The results implicate a failure of growth control in NF1, leading to aberrant neurodevelopment. Our findings also suggest a basis for refined understanding of learning disabilities, which are a prominent feature of NF1.

Abstract
Seventy patients, aged 1-20 years, were seen at Jordan University Hospital with high blood pressure (BP) over a 3-year period. BP values ranged from 140 to 230 mmHg for systolic pressure and from 90 to 130 mmHg for diastolic pressure. Essential hypertension was seen in only 6 patients (8.6%); secondary hypertension (n = 64 or 91.4%) was due to renal parenchymal diseases (RPD) in 46 patients (65.7%), reno-vascular lesions in 8 (11.4%), renal transplantation in 5 (7.2%), teenage pregnancy in 4 (5.7%), and phaeochromocytoma in 1 patient (1.4%). The aetiologies of RPD were as follows: end-stage renal disease requiring dialysis in 14 patients, acute glomerulonephritis in 14, idiopathic nephrotic syndrome in 10, chronic renal insufficiency in 5, and polycystic kidney in 3 patients. Surgical cure of hypertension was achieved in 5 of the children with reno-vascular lesions and in the patient with phaeochromocytoma.
