Abstract
Background and Aim The prognostic potential of cardiac troponin (cTn) in acute stroke patients has been a subject of ongoing debate. Our objective was to provide a comprehensive evidence for predicting mortality in acute stroke patients by using the elevated troponin levels. Methods We conducted an extensive literature search, including PubMed, EMbase, and Trip Databases, covering studies published up to September 30, 2023. We computed risk ratios (RR) with 95% confidence intervals (CIs), performed sensitivity analysis, and conducted trial sequential analysis (TSA). Results In total, 53 studies were analyzed, with 37 focusing on acute ischemic stroke (AIS), 11 on subarachnoid hemorrhage (SAH), and 7 on Intracerebral hemorrhage (ICH). Elevated cTn levels were significantly showed a higher predictive risk for In-hospital mortality in both AIS (RR=3.80, 95% CI; 2.82 to 5.12) as well as SAH (RR=2.23, 95% CI; 1.64 to 3.02). However, no significant predictive risk between elevated cTn levels and in-hospital mortality for ICH patients (RR=1.13, 95% CI: 0.46 to 2.79). A similar pattern was observed for elevated cTn levels, indicating an increased risk of last follow-up mortality for AIS (RR=2.41, 95% CI: 1.98 to 2.93) and SAH (RR=3.08, 95% CI: 2.25 to 4.21). Conclusion Elevated troponin levels can serve as a promising predictive marker for both in-hospital and last follow-up mortality in AIS and SAH patients but not in ICH patients. Further prospective studies are needed to validate our findings along with exploring the preventive management of mortality in acute stroke settings.

Abstract
INTRODUCTION Subarachnoid hemorrhage (SAH) is caused by a ruptured intracranial aneurysm leading to acute extravasation of blood into the subarachnoid space. SAH has an incidence of 6.3 per 100,000 persons per year in Europe and accounts for 5% of all strokes. SAH occurs at a relatively young age and has poor clinical outcomes and high mortality rates. Cardiac syndromes are regularly seen in patients with acute neurologic disease including SAH. These cardiac complications of SAH are associated with increased morbidity and mortality and present in a large variety and severity. AREAS COVERED The main goal of this review is to describe the SAH-related cardiac syndromes. Secondly, we will provide an overview of the underlying pathophysiology regarding the development of cardiac syndromes. Thirdly, we will describe the impact of cardiac syndromes on patient outcome. EXPERT OPINION Of all neurology patients, SAH patients have the highest risk of developing takotsubo syndrome (TTS), occurring in about 0.8-30% of patients. Both TTS and neurogenic stunned myocardium have many similarities on echocardiographic evaluation. In European Cardiology consensus, SAH is recognized as a primary cause of TTS.

Evaluation of Cardiac Troponin and Adverse Outcomes After Aneurysmal Subarachnoid Hemorrhage: A Systematic Review and Meta-Analysis. Neurocrit Care 2021; 36:650-661. [PMID: 34686997 DOI: 10.1007/s12028-021-01368-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2021] [Accepted: 09/24/2021] [Indexed: 10/20/2022]
Abstract
Several studies have demonstrated the usefulness of cardiac troponin I (cTn) levels in predicting adverse clinical outcomes of patients with anerusmal subarachnoid hemorrhage (aSAH). However, it remains unclear whether cTn levels can be a useful factor in predicting adverse neurologic and cardiovascular outcomes regarding follow-up duration. The study aimed to evaluate the clinical value of cTn elevation among patients with aSAH. A systematic literature search was performed in PubMed and Cochrane to collect original studies that compared the adverse outcomes in patients with aSAH who had elevated cTn levels and those who did not have elevated cTn levels. Data on patient demographics and outcome measurements (mortality, major disability, delayed cerebral ischemia, cardiac dysfunction, and pulmonary edema) were extracted. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were computed by fitting a random effects model. A total of 4,117 patients with aSAH were included in the meta-analysis. Elevated cTn levels was associated with a higher all-cause mortality (OR 3.64; 95% CI 2.68-4.94; I2 = 22.05%), poor major disability (OR 2.27; 95% CI 1.5-3.37; I2 = 52.07%), delayed cerebral ischemia (OR 2.10; 95% CI 1.46-3.03; I2 = 13.80%), cardiac dysfunction (OR 9.20; 95% CI 4.31-19.60; I2 = 39.89), and pulmonary edema (OR 10.32; 95% CI 5.64-18.90; I2 = 0.00%). Additionally, elevated cTn levels was associated with higher mortality in prospective studies (OR 3.66; 95% CI 2.61-5.14) as well as when compared with studies with short-term and long-term follow-up periods. Patients with aSAH who had elevated cTn levels also tended to experience poor short-term major disability (OR 2.36; 95% CI 1.48-3.76). Among patients with aSAH, elevated cTn levels was associated with higher mortality and adverse neurologic and cardiovascular outcomes. Given its clinical value, cardiac troponin levels may be included in the assessment of patients withs aSAH.

Abstract
Object: Patients with aneurysmal subarachnoid hemorrhage (aSAH) have an increased incidence of cardiac events and short-term unfavorable neurological outcomes during the acute phase of bleeding. We studied whether troponin I elevation after ictus can predict future major adverse cardiac events (MACEs) and long-term neurological outcomes after 2 years. Methods: Consecutive aSAH patients within 3 days of bleeding were eligible for review from a prospective observational cohort (ClinicalTrials.gov Identifier: NCT04785976). Potential predictors of future MACEs and unfavorable long-term neurological outcomes were calculated by Cox and logistic regression analyses. Additional Kaplan–Meier curves were performed. Results: A total of 213 patients were enrolled with an average follow-up duration of 34.3 months. Individuals were divided into two groups: elevated cTnI group and unelevated cTnI group. By the last available follow-up, 20 patients had died, with an overall all-cause mortality rate of 9.4% and an annual all-cause mortality rate of 3.8%. Patients with elevated cTnI had a significantly higher risk of future MACEs (10.6 vs. 2.1%, p = 0.024, and 95% CI: 1.256–23.875) and unfavorable neurological outcomes at discharge, 3-month, 1-, 2-years, and last follow-up (p = 0.001, p < 0.001, p = 0.001, p < 0.001, and p < 0.001, respectively). In the Cox analysis for future MACE, elevated cTnI was the only independent predictor (HR = 5.980; 95% CI: 1.428–25.407, and p = 0.014). In the multivariable logistic analysis for unfavorable neurological outcomes, peak cTnI was significant (OR = 2.951; 95% CI: 1.376–6.323; p = 0.005). Kaplan–Meier analysis indicated that the elevated cTnI was correlated with future MACE (log-rank test, p = 0.007) and subsequent death (log-rank test, p = 0.004). Conclusion: cTnI elevation after aSAH could predict future MACEs and unfavorable neurological outcomes.

Abstract
Many cardiopulmonary complications occur after aneurysmal subarachnoid hemorrhage. This is due to sympathetic nervous system activation which results in release of norepinephrine from myocardial sympathetic nerves. Cardiac troponin I is a marker for diagnosis of cardiac injury. Elevated levels of troponin in these patients are associated with worse clinical outcomes. PubMed was searched for literature using regular and Medical Subject Heading (MeSH) keywords for data collection. Papers published in English language involving human subjects within the last 20 years focusing on cardiac troponin elevation following subarachnoid hemorrhage were included. Systemic complications that occur after subarachnoid hemorrhage worsen the clinical outcome of patients and have negative effects on the mortality and morbidity of these patients. Cardiac troponin I elevation is significantly associated with the severity of the stroke, poor neurological status, longer ICU stay, and death. Cardiac troponin I should be measured in patients presented with acute stroke. Hemodynamic monitoring and appropriate supportive care can improve clinical outcomes.

Abstract
OBJECTIVE Cardiopulmonary (CP) complications are well-known phenomena after an isolated traumatic brain injury (iTBI) and they may be associated with an elevated serum troponin I (TnI) value. However, the influence of an elevated TnI level on CP parameters within the first 24 h after an iTBI is still unknown. The current study was conducted to assess the associations between the initial TnI value on admission and CP parameters during the first 24 h of intensive care unit (ICU) treatment in iTBI patients. PATIENTS AND METHODS A total of 288 patients with iTBIs, who were admitted to our emergency department between January 2010 and November 2016 were retrospectively analyzed. Blood samples were taken on admission to determine TnI value. Each patient's demographic data, treatment regime, computed tomography results, and intra-hospital outcomes were evaluated, as well as several CP parameters, within the first 24 h of ICU treatment. The entire study population was stratified into patients with an initial TnI elevation (TnI positive) and without an initial TnI elevation (TnI negative). RESULTS Increased TnI values on admission were found in 59 (20.5%) patients. There were significant correlations between an initially elevated TnI value and a lower Glasgow Coma Scale score (p = 0.003), higher head Abbreviated Injury Scale score (p<0.0001), and higher Acute Physiology and Chronic Health Evaluation II score (p = 0.005) on admission, as well as a lower Glasgow Outcome Scale score (p = 0.0002) and higher modified Rankin Scale score (p = 0.0001) at discharge. In addition, a significantly higher norepinephrine application rate (NAR) (p<0.0001) and inspiratory oxygen fraction (FiO2) (p = 0.028) were needed in the TnI positive group. CONCLUSION Patients with elevated TnI values on admission require more circulation support (NAR and FiO2) within the first 24 h of ICU treatment after an iTBI. Therefore, the TnI may be a useful biomarker to improve ICU treatment of these patients.

Abstract
Objective: To evaluate the prognostic value of high-sensitivity troponin (hsT) in severe aneurysmal subarachnoid hemorrhage (aSAH). Methods: This prospective non-interventional study was performed at a surgical intensive care unit (ICU) from 2012 to 2015. Consecutive patients who had severe aSAH were included. A modified Rankin Scale score ≥ 4 or death within 3 months defined a poor outcome. hsT levels were measured at ICU admission and 72 hours following symptom onset. Results: A total of 137 patients were analyzed. The median hsT level was 29 ng/L (range: 7-4485). The best threshold level of hsT for predicting a poor outcome was 22 ng/L. At this threshold, the sensitivity was 71% (95% confidence interval [CI]: 58%-81%) and the specificity was 58% (95%CI: 46%-70%). The area under the ROC curve was 0.61 (95%CI: 0.52-0.71). Based on a multivariate analysis, the independent factors for a poor neurological prognosis were a World Federation of Neurologic Surgeons (WFNS) score ≥ 4 (odds ratio [OR]: 2.61; 95%CI: 1.04-6.56) and an hsT level > 22 ng/L (OR: 2.80; 95%CI: 1.18-6.64). Conclusion: In patients with severe aSAH, with regard for the severity of disease (assessed by the WFNS score), an hsT level > 22 ng/L at ICU admission was associated with poor outcomes.

Abstract
OBJECTIVE Cardiopulmonary complications/stress are well-known phenomena in patients after aneurysmal subarachnoid hemorrhage (aSAH) and might be associated with an elevated serum troponin I (TNI) level. Since the glucocorticoid hormone cortisol is released during stress situations, the present study was conducted to investigate the influence of serum cortisol (SC) on cardiac and pulmonary parameters in patients after aSAH within the first 24 hours of intensive care unit (ICU) treatment. PATIENTS AND METHODS We retrospectively analyzed a cohort of 104 patients with aSAH admitted to our emergency department between January 2008 and April 2017. Blood samples were taken to determine SC and TNI. Demographics, initial Glasgow Coma Scale (GCS) score, World Federation of Neurosurgical Societies (WFNS) score, and Fisher grade were evaluated retrospectively. Mean norepinephrine application rate (NAR) in µg/kg/min and mean inspiratory oxygen fraction (OF) within the first 24 hours were defined as cardiopulmonary parameters. RESULTS An elevated SC value was found in 44 (42%) patients, and 27 (26%) patients showed an increased TNI value. In patients with initially increased SC value, a significant higher NAR (P = .04) was needed. Furthermore, patients with initially elevated TNI value had a lower GCS score (P = .0013) and a higher WFNS score (P = .003) on admission and required a higher NAR (P = .02) as well as OF (P = .0008) within the first 24 hours of ICU treatment. CONCLUSIONS In the current study, initially elevated SC values were associated with a higher need of NAR within the first 24 hours of ICU treatment after aSAH. Moreover, patients with initially elevated TNI values required an increased NAR and a higher OF so that these biomarkers could be useful to improve ICU treatment.

Abstract
OBJECTIVE The elevation of serum cardiac troponin I (TNI) in patients with nontraumatic subarachnoid hemorrhage (ntSAH) is a well-known phenomenon. However, the relation between elevated TNI and different cardiopulmonary parameters (CPs) within the first 24 hours after ntSAH is unknown. The present study was conducted to investigate the association between TNI and different CP in patients with ntSAH within the first 24 hours of intensive care unit (ICU) treatment. PATIENTS AND METHODS We retrospectively analyzed a consecutive group of 117 patients with ntSAH admitted to our emergency department between January 2008 and February 2017. Blood samples were taken to determine TNI values on admission. Demographic data, baseline Glasgow Coma Scale (GCS) score, World Federation of Neurosurgical Societies (WFNS) score, baseline Fisher grade (FG), norepinephrine application rate (NAR) in µg/kg/min, and inspiratory oxygen fraction (OF) were recorded within the first 24 hours. RESULTS An increased TNI value was found in 32 (27.4%) of 117 patients. There was a significant correlation between initial elevated TNI and a low WFNS score (P = .007), a low GCS score (P = .003) as well as a high OF (P = <.001). The FG (P = .27) and NAR (P = .08) within the first 24 hours of ICU treatment did not show any significant correlation. CONCLUSIONS In the present study, an increased TNI value was significantly associated with a low WFNS score and GCS score on admission. The TNI was a predictor of the need for a higher OF within the first 24 hours after ntSAH so that TNI could be an informative biomarker to improve ICU therapy.

Abstract
OBJECTIVE The association between brain injury and elevated serum cardiac troponin (cTn) remains poorly understood. We conducted a systematic review and meta-analysis to evaluate whether elevated cTn increases the risk of mortality in patients with traumatic (TBI) or non-traumatic brain injury (NT-BI). METHODS Cochrane Library, MEDLINE, PubMed, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), WHO International Clinical Trials Registry Platform, and Google scholar databases, and clinicaltrials.gov were searched for a retrospective, prospective and randomized clinical trials (RCT) or quasi-RCT studies that assessed the effect of elevated cTn (conventional or high sensitive assay) on the outcomes of brain injury patients. The main outcome of interest was mortality. Two authors independently abstracted the data using a data collection form. Results from different studies were pooled for analysis, whenever appropriate. The total number of patients pooled was 2435, of which 916 had elevated cTn and 1519 were in control group. RESULTS Out of 691 references identified through the search, 8 analytical studies met inclusion criteria. Among both types of brain injuries, an elevated cTn was associated with a higher mortality with an overall pooled odd ratio (OR) of 3.37 (95% CI 2.13-5.36). The pooled OR for mortality was 3.31 (95% CI 1.99-5.53) among patients with TBI and 3.36 (95% CI 1.32-8.6) among patients with NT-BI. CONCLUSIONS Pooled analysis indicates that elevated cTn is significantly associated with a high mortality in patients with TBI and NT-BI. Prospective clinical trials are needed to support these findings and to inform a biomarker risk stratification regardless of the mechanism of injury.

Abstract
The cardiovascular manifestations associated with nontraumatic head disorders are commonly known. Similar manifestations have been reported in patients with traumatic brain injury (TBI); however, the underlying mechanisms and impact on the patient's clinical outcomes are not well explored. The neurocardiac axis theory and neurogenic stunned myocardium phenomenon could partly explain the brain-heart link and interactions and can thus pave the way to a better understanding and management of TBI. Several observational retrospective studies have shown a promising role for beta-adrenergic blockers in patients with TBI in reducing the overall TBI-related mortality. However, several questions remain to be answered in clinical randomized-controlled trials, including population selection, beta blocker type, dosage, timing, and duration of therapy, while maintaining the optimal mean arterial pressure and cerebral perfusion pressure in patients with TBI.

Zhang L, Zhang B, Qi S. Impact of echocardiographic wall motion abnormality and cardiac biomarker elevation on outcome after subarachnoid hemorrhage: a meta-analysis. Neurosurg Rev 2018; 43:59-68. [PMID: 29804158 DOI: 10.1007/s10143-018-0985-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2018] [Revised: 04/30/2018] [Accepted: 05/15/2018] [Indexed: 11/24/2022]
Abstract
Cardiac abnormalities (echocardiographic wall motion abnormality (WMA), biomarker elevation of cardiac troponin (cTn), B-type natriuretic peptide (BNP), or N-terminal prohormone of B-type natriuretic peptide (NT-proBNP)) frequently occur after subarachnoid hemorrhage (SAH). The clinical significance of cardiac abnormalities after SAH remains controversial. This meta-analysis was performed to assess the association between cardiac abnormalities and patient outcomes, including delayed cerebral ischemia (DCI), poor outcome, and death in SAH patients. PubMed and Embase were searched for observational studies reporting an association between cardiac abnormalities and outcome after SAH that were published before 31 December 2017. We extracted data regarding patient characteristics, cardiac abnormalities, and outcome measurements (DCI, poor outcome, or death). Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using a random-effects model. Twenty-six studies involving 3917 patients were included in our data analysis. WMA showed significant associations with higher rates of DCI (RR, 2.03; 95% CI, 0.99-4.15), poor outcome (RR, 1.45; 95% CI, 1.08-1.93), and death (RR, 2.54; 95% CI, 1.59-4.05). cTn elevation was associated with an increased risk of DCI (RR, 1.48; 95% CI, 1.23-1.79), poor outcome (RR, 1.85; 95% CI, 1.49-2.30), and death (RR, 2.68; 95% CI, 2.19-3.27). Elevation of BNP or NT-proBNT was significantly associated with higher rates of DCI (RR, 1.87; 95% CI, 1.16-3.02). WMA and elevation of cTn, BNP, and NT-proBNP in SAH patients are associated with an increased risk of DCI, poor outcome, and death after SAH.

Abstract
Neurocardiology refers to the interplay between the nervous system and the cardiovascular system. Stress-related cardiomyopathy exemplifies the brain-heart connection and occurs in several conditions with acute brain injury that share oversympathetic activation. The brain's influences on the heart can include elevated cardiac markers, arrhythmias, repolarization abnormalities on electrocardiogram, myocardial necrosis, and autonomic dysfunction. The neurogenic stunned myocardium in aneurysmal subarachnoid hemorrhage represents one end of the spectrum, and is associated with an explosive rise in intracranial pressure that results in excess catecholamine state and possibly CBN. A brain-heart link is more known to cardiologists than neurologists. This chapter provides some insight into the pathophysiology of these pathologic neurocardiac states and their most appropriate management relevant to neurologists.

Abstract
INTRODUCTION Patients with spontaneous sub-arachnoid hemorrhage (SAH) might develop various cardiac abnormalities, however; the prognostic implications of these cardiac abnormalities are not well known. This study aimed to detect the cardiac abnormality that correlates best with in-hospital all-cause mortality in patients with SAH. METHODS In this retrospective study, all patients admitted to our institution with a primary diagnosis of SAH, and underwent a transthoracic echocardiogram (TTE) from July 2011 until May 2014, were enrolled. Data gathered included patients' demographics, Hunt and Hess clinical grading, computed tomography SAH Fisher grading, troponin T level, electrocardiographic (ECG) changes, TTE, and in-hospital all-cause mortality. Multivariate logistic regression of the cardiac abnormalities and in-hospital all-cause mortality was performed. RESULTS A total of 247 patients were included in our analysis. In-hospital all-cause mortality was 15.6% (38 patients). The presence of elevated troponin T levels, resting segmental wall motion abnormalities, reduced ejection fraction (<35%), and prolonged corrected QT interval (QTc) on ECG were associated with increased in-hospital all-cause mortality on univariate analysis. On multivariable regression, QTc prolongation was the only independent predictor for in-hospital all-cause mortality (p = 0.04). CONCLUSIONS Prolonged QTc interval on ECG was independently associated with in-hospital all-cause mortality in patients presenting with spontaneous SAH. Whether this is a causative association or a marker of underlying severe clinical presentation of SAH remains unknown.

Quintard H, Leduc S, Ferrari P, Petit I, Ichai C. Early and persistent high level of PS 100β is associated with increased poor neurological outcome in patients with SAH: is there a PS 100β threshold for SAH prognosis? CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2016; 20:33. [PMID: 26843206 PMCID: PMC4738799 DOI: 10.1186/s13054-016-1200-1] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/20/2015] [Accepted: 01/16/2016] [Indexed: 01/15/2023]
Abstract
BACKGROUND Protein S100β (PS100 β) and neuron specific enolase (NSE) have been described as biological markers of neuronal damage. The purpose of our study was to assess the prognosis thresholds of these biomarkers in subarachnoid aneurysmal hemorrhage (SAH). METHODS Forty eight patients admitted following SAH were treated by endovascular coiling. Initial neurologic severity was assessed using the World Federation Neurologic Surgeons (WFNS), Fisher grades, initial Glasgow coma scale (GCS) and SAPS II. PS100β and NSE plasma concentration were measured daily within the first week. The primary endpoint of the study was the 6-month Glasgow Outcome Score (GOS) dichotomized as poor (GOS 1-3) or good (GOS 4-5). RESULTS A poor outcome at 6-months was associated with significant higher levels of S100β value from day 1 to day 7, whereas NSE values were significantly higher from day 5 to day 7. Best threshold value, for prognosis, was obtained at day 5 for PS100β >0.13 μg/L (specificity 0.95 95% confidence interval (CI) 0.74-1; sensitivity 0.83 95% CI 0.65-0.93) and day 7 for NSE >14.5 μg/L (specificity 0.90 95% CI 0.67-0.98); sensitivity (0.69 95% CI 0.51-0.83)). After multivariate logistic analysis, only PS100β at day 5 and SAPS II enabled to predict neurological outcome at 6 months (p<0.05). CONCLUSION PS100β >0.13 μg/L at day 5 is an independent predicting factor of poor neurological outcome at 6 months following SAH. This result could support the use of this biomarker at the acute phase of SAH to help physician determine the prognosis.

Abstract
Cardiac manifestations are recognized complications of subarachnoid hemorrhage. Neurogenic stress cardiomyopathy is one complication that is seen in acute subarachnoid hemorrhage. It can present as transient diffuse left ventricular dysfunction or as transient regional wall motion abnormalities. It occurs more frequently with neurologically severe-grade subarachnoid hemorrhage and is associated with increased morbidity and poor clinical outcomes. Managing this subset of patients is challenging. Early identification followed by a multidisciplinary team approach can potentially improve outcomes.

Abstract
BACKGROUND Cardiac abnormalities frequently occur after subarachnoid hemorrhage (SAH). Cardiac troponin (cTn) is a preferred biomarker for the diagnosis of cardiac damage, and the clinical significance of cTn elevation after SAH remains controversial. This meta-analysis was performed to assess the association between cTn elevation and patient outcomes, including delayed cerebral ischemia (DCI), poor outcome (death or dependency), and death in SAH patients. METHODS PubMed, Embase, and the Cochrane Library were searched for observational studies reporting an association between cTn elevation and outcome after SAH that were published before December 31, 2014. We extracted data regarding patient characteristics, cTn elevation, and outcome measurements (DCI, poor outcome, or death). Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using a random-effects model. RESULTS Twelve studies involving 2214 patients were included in data analysis. Elevation of cTn was observed in 30% of the patients. The cTn elevation was associated with an increased risk of DCI (RR, 1.48; 95% CI, 1.23-1.79), poor outcome (RR, 1.91; 95% CI, 1.51-2.40), and death (RR, 2.53; 95% CI, 2.04-3.12). At the 3- and 12- month follow-ups, cTn elevation was associated with higher rates of DCI (RR, 1.51; 95% CI, 1.11-2.07), poor outcome (RR, 1.91; 95% CI, 1.51-2.40), and death (RR, 2.78; 95% CI, 1.80-4.29). At in-hospital follow-ups, cTn elevation was also associated with the higher rate of death (RR, 2.33; 95% CI, 1.76-3.07). CONCLUSIONS cTn elevation in SAH patients is associated with an increased risk of DCI, poor outcome, and death after SAH.

Abstract
OBJECTIVES Reversible stress-induced cardiac dysfunction is frequently seen as a complication of a multitude of acute stress states, in particular neurologic injuries. This dysfunction may be difficult to distinguish between that caused by myocardial ischemia and may impact both the treatment strategies and prognosis of the underlying condition. Critical care practitioners should have an understanding of the epidemiology, pathophysiology, clinical characteristics, precipitating conditions, differential diagnosis, and proposed treatments for stress-induced cardiomyopathy. DATA SOURCES MEDLINE database search conducted from inception to August 2014, including the search terms "tako-tsubo," "stress-induced cardiomyopathy," "neurogenic cardiomyopathy," "neurogenic stress cardiomyopathy," and "transient left ventricular apical ballooning syndrome". In addition, references from pertinent articles were used for a secondary search. STUDY SELECTION AND DATA EXTRACTION After review of peer-reviewed original scientific articles, guidelines, and reviews resulting from the literature search described above, we made final selections for included references and data based on relevance and author consensus. DATA SYNTHESIS Stress-induced cardiomyopathy occurs most commonly in postmenopausal women. It can be precipitated by emotional stress, neurologic injury, and numerous other stress states. Patients may present with symptoms indistinguishable from acute coronary syndrome or with electrocardiogram changes and wall motion abnormalities on echocardiogram following neurologic injury. Nearly all patients will have an elevated cardiac troponin. The underlying etiology is likely related to release of catecholamines, both locally in the myocardium and in the circulation. Differential diagnosis includes myocardial infarction, myocarditis, neurogenic pulmonary edema, and nonischemic cardiomyopathy. Although the natural course of stress-induced cardiomyopathy is resolution, treatment strategies include sympathetic blockade and supportive care. CONCLUSIONS Stress-induced cardiomyopathy may mimic myocardial infarction and is an important condition to recognize in patients with underlying stress states, particularly neurologic injuries.

Abstract
Nontraumatic subarachnoid hemorrhage from intracranial aneurysm rupture presents with sudden severe headache. Initial treatment focuses on airway management, blood pressure control, and extraventricular drain for hydrocephalus. After identifying the aneurysm, they may be clipped surgically or endovascularly coiled. Nimodipine is administered to maintain a euvolemic state and prevent delayed cerebral ischemia (DCI). Patients may receive anticonvulsants. Monitoring includes serial neurologic assessments, transcranial Doppler ultrasonography, computed tomography perfusion, and angiographic studies. Treatment includes augmentation of blood pressure and cardiac output, cerebral angioplasty, and intra-arterial infusions of vasodilators. Although early mortality is high, about one half of survivors recover with little disability.
