Abstract
Intracerebral hemorrhage (ICH) stands as a prevalent and pivotal clinical condition. The potential cooccurrence of acute kidney injury (AKI) among afflicted individuals can profoundly influence their prognosis. In recent times, there has been a growing focus among clinical practitioners on researching the relationship between ICH and AKI. AKI occurring concurrently with ICH predominantly arises from both hemodynamic and non-hemodynamic mechanisms. The latter encompasses neurohumoral regulation, inflammatory response, oxidative stress, and iatrogenic factors such as contrast agents, dehydrating agents, antibiotics, and diuretics. Moreover, advanced age, hypertension, elevated baseline creatinine levels, chronic kidney disease, and larger hematomas predispose patients to AKI. Additionally, the current utilization of biomarkers and the development of predictive models appear promising in identifying patients at risk of AKI after ICH. This article aims to underscore the potential of the aforementioned insights to inspire novel approaches to early clinical intervention.

Cerebrospinal Fluid and Serum Biomarker Insights in Aneurysmal Subarachnoid Haemorrhage: Navigating the Brain-Heart Interrelationship for Improved Patient Outcomes. Biomedicines 2023; 11:2835. [PMID: 37893210 PMCID: PMC10604203 DOI: 10.3390/biomedicines11102835] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 10/05/2023] [Accepted: 10/17/2023] [Indexed: 10/29/2023] Open
Abstract
The pathophysiological mechanisms underlying severe cardiac dysfunction after aneurysmal subarachnoid haemorrhage (aSAH) remain poorly understood. In the present study, we focused on two categories of contributing factors describing the brain-heart relationship. The first group includes brain-specific cerebrospinal fluid (CSF) and serum biomarkers, as well as cardiac-specific biomarkers. The secondary category encompasses parameters associated with cerebral autoregulation and the autonomic nervous system. A group of 15 aSAH patients were included in the analysis. Severe cardiac complications were diagnosed in seven (47%) of patients. In the whole population, a significant correlation was observed between CSF S100 calcium-binding protein B (S100B) and brain natriuretic peptide (BNP) (rS = 0.62; p = 0.040). Additionally, we identified a significant correlation between CSF neuron-specific enolase (NSE) with cardiac troponin I (rS = 0.57; p = 0.025) and BNP (rS = 0.66; p = 0.029), as well as between CSF tau protein and BNP (rS = 0.78; p = 0.039). Patients experiencing severe cardiac complications exhibited notably higher levels of serum tau protein at day 1 (0.21 ± 0.23 [ng/mL]) compared to those without severe cardiac complications (0.03 ± 0.04 [ng/mL]); p = 0.009. Impaired cerebral autoregulation was noted in patients both with and without severe cardiac complications. Elevated serum NSE at day 1 was related to impaired cerebral autoregulation (rS = 0.90; p = 0.037). On the first day, a substantial, reciprocal correlation between heart rate variability low-to-high frequency ratio (HRV LF/HF) and both GFAP (rS = -0.83; p = 0.004) and S100B (rS = -0.83; p = 0.004) was observed. Cardiac and brain-specific biomarkers hold the potential to assist clinicians in providing timely insights into cardiac complications, and therefore they contribute to the prognosis of outcomes.

Abstract
BACKGROUND Subarachnoid haemorrhage (SAH) is a life-threatening condition with associated brain damage. Moreover, SAH is associated with a massive release of catecholamines, which may promote cardiac injury and dysfunction, possibly leading to haemodynamic instability, which in turn may influence a patient's outcome. OBJECTIVES To study the prevalence of cardiac dysfunction (as assessed by echocardiography) in patients with SAH and its effect on clinical outcomes. DESIGN Systematic review of observational studies. DATA SOURCES We performed a systematic search over the last 20 years on MEDLINE and EMBASE databases. ELIGIBILITY CRITERIA Studies reporting echocardiography findings in adult patients with SAH admitted to intensive care. Primary outcomes were in-hospital mortality and poor neurological outcome according to the presence or absence of cardiac dysfunction. RESULTS We included a total of 23 studies (4 retrospective) enrolling 3511 patients. The cumulative frequency of cardiac dysfunction was 21% (725 patients), reported as regional wall motion abnormality in the vast majority of studies (63%). Due to the heterogeneity of clinical outcome data reporting, a quantitative analysis was carried out only for in-hospital mortality. Cardiac dysfunction was associated with a higher in-hospital mortality [odds ratio 2.69 (1.64 to 4.41); P < 0.001; I2 = 63%]. The GRADE of evidence assessment resulted in very low certainty of evidence. CONCLUSION About one in five patients with SAH develops cardiac dysfunction, which seems to be associated with higher in-hospital mortality. The consistency of cardiac and neurological data reporting is lacking, reducing the comparability of the studies in this field.

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.

Abstract
Background Takotsubo cardiomyopathy (TTC) is an important complication of subarachnoid hemorrhage (SAH), that may delay surgical or endovascular treatment and may influence patient outcome. This prospective follow-up study intended to collect data on the prevalence, severity, influencing factors and long-term outcome of TTC in patients suffering from non-traumatic SAH. Methods Consecutive patients admitted with the diagnosis of non-traumatic SAH were included. Intitial assessment consisted of cranial CT, Hunt-Hess, Fisher and WFNS scoring, 12-lead ECG, transthoracic echocardiography (TTE), transcranial duplex sonography and collecting laboratory parameters (CK, CK-MB, cardiac troponin T, NT-proBNP and urine metanephrine and normetanephrine). Diagnosis of TTC was based on modified Mayo criteria. TTC patients were dichotomized to mild and severe forms. Follow-up of TTE, Glasgow Outcome Scale assessment, Barthel’s and Karnofsky scoring occurred on days 30 and 180. Results One hundred thirty six patients were included. The incidence of TTC in the entire cohort was 28.7%; of them, 20.6% and 8.1% were mild and severe, respectively. TTC was more frequent in females (30/39; 77%) than in males (9/39; 23%) and was more severe. The occurrence of TTC was related to mFisher scores and WFNS scores. Although the severity of TTC was related to mFisher score, Hunt-Hess score, WFNS score and GCS, multivariate analysis showed the strongest relationship with mFisher scores. Ejection fraction differences between groups were present on day 30, but disappeared by day 180, whereas wall motion score index was still higher in the severe TTC group at day 180. By the end of the follow-up period (180 days), 70 (74.5%) patients survived in the non-TTC, 22 (81.5%) in the mild TTC and 3 (27%) in the severe TTC group (n = 11) (p = 0.002). At day 180, GOS, Barthel, and Karnofsky outcome scores were higher in patients in the control (non-TTC) and the mild TTC groups than in the severe TTC group. Conclusions Takotsubo cardiomyopathy is a frequent finding in patients with SAH, and severe TTC may be present in 8% of SAH cases. The severity of TTC may be an independent predictor of mortality and outcome at 6 months after disease onset. Therefore, a regular follow-up of ECG and TTE abnormalities is warranted in patients with subrachnoid hemorrhage for early detection of TTC. Trial registration The study was registered at the Clinical Trials Register under the registration number of NCT02659878 (date of registration: January 21, 2016).

Abstract
INTRODUCTION Non-traumatic subarachnoid hemorrhage (SAH) is a type of stroke that still has a high mortality rate. Some patients with SAH have electrocardiography (ECG) abnormalities or asymptomatic left ventricular apical ballooning, and requires intervention by cardiologists. However, the impact of cardiac abnormalities after SAH onset remains unclear. We investigated whether ECG abnormalities, myocardial damage, sympathetic nervous activity or echocardiographic left ventricular wall motion abnormalities (WMA) could provide additional risk stratification in patients with SAH. METHODS We studied 118 SAH patients (78 women, age 63 ± 15) without a history of heart disease. Neurological grade (Hunt and Kosnik Grade) and clinical factors were evaluated. A standard 12-lead ECG, echocardiography and blood samples were obtained within 48 h after SAH onset. ECG abnormalities were defined as abnormal Q wave, ST elevation, giant T-wave inversion or QT prolongation. RESULTS Twenty of 118 patients (17%) died during the follow-up (35 ± 31 months). Death was significantly associated with higher age (p < 0.0001), neurological grade (p < 0.0001), elevated BNP level (p < 0.0001), increased plasma norepinephrine levels (p < 0.0001) and WMA (p = 0.0070), while ECG abnormalities were not significantly associated. Neurological grade (p < 0.0001), age (p = 0.0047) and BNP (p = 0.0014, hazard ratio 1.0255 for each 1 pg/mL increase in BNP, 95%CI 1.0088 to 1.0499) were independently associated with death. Patients with BNP ≥ 96.6 had a higher risk of death (log- rank p < 0.0001). CONCLUSION Plasma BNP might provide an additional risk stratification in patients with non-traumatic SAH that requires intervention by cardiologists for both its prevention management after onset.

Abstract
A number of neurologic disorders can cause cardiac dysfunction by involving the conductive system and contractile apparatus of the heart. This is especially prominent in the neurocritical care setting where the spectrum of cardiac dysfunction due to acute neurologic injury ranges from trivial and isolated electrocardiographic changes to malignant arrhythmias and sudden death (Table 1). The mechanism of these cardiac complications is complex and not fully understood. An understanding of the neuroanatomical structures and pathways is of immense importance to comprehend the underlying pathophysiology that culminates as cardiac damage and dysregulation. Once the process is initiated, it can complicate and adversely affect the outcome of primary neurologic conditions commonly seen in the neurocritical care setting. Not only are these cardiac disorders under-recognized, there is a paucity of data to formulate evidence-based guidelines regarding early detection, acute management, and preventive strategies. However, certain details of clinical features and their course combined with location of primary neurologic lesion on neuroimaging and data obtained from laboratory investigations can be of great value to develop a strategy to appropriately manage these patients and to prevent adverse outcome from these cardiac complications. In this review, we highlight the mechanisms of cardiac dysfunction due to catastrophic neurologic conditions or due to stress of critical illness. We also address various clinical syndromes of cardiac dysfunction that occur as a result of the neurologic illness and in turn may complicate the course of the primary neurologic condition.

Abstract
INTRODUCTION Neurocardiac injury, a type of myocardial dysfunction associated with neurological insult to the brain, occurs in 31-48% of aneurysmal subarachnoid hemorrhage (aSAH) patients. Cardiac troponin I (cTnI) is commonly used to diagnose neurocardiac injury. Brain natriuretic peptide (BNP), another cardiac marker, is more often used to evaluate degree of heart failure. The purpose of this study was to examine the relationships between BNP and (a) neurocardiac injury severity according to cTnI, (b) noninvasive continuous cardiac output (NCCO), and (c) outcomes in aSAH patients. METHOD This descriptive longitudinal study enrolled 30 adult aSAH patients. Data collected included BNP and cTnI levels and NCCO parameters for 14 days and outcomes (modified Rankin Scale [mRS] and mortality) at discharge and 3 months. Generalized estimating equations were used to evaluate associations between BNP and cTnI, NCCO, and outcomes. RESULTS BNP was significantly associated with cTnI. For every 1 unit increase in log BNP, cTnI increased by 0.05 ng/ml ( p = .001). Among NCCO parameters, BNP was significantly associated with thoracic fluid content ( p = .0003). On multivariable analyses, significant associations were found between BNP and poor mRS. For every 1 unit increase in log BNP, patients were 3.16 times more likely to have a poor mRS at discharge ( p = .021) and 5.40 times more likely at 3 months ( p < .0001). CONCLUSION There were significant relationships between BNP and cTnI and poor outcomes after aSAH. BNP may have utility as a marker of neurocardiac injury and outcomes after aSAH.

Abstract
A 36-year-old man was brought to our emergency department after successful resuscitation of out-of-hospital cardiac arrest with the whole spectrum of neurocardiogenic effects in subarachnoid hemorrhage: electrocardiographic changes, regional wall motion abnormalities, and elevations of cardiac enzymes. Coronary angiography revealed normal coronary arteries but showed the midventricular type of Takotsubo cardiomyopathy in the left ventriculography. Subsequently, cerebral computed tomography revealed diffuse subarachnoid hemorrhage and generalized cerebral edema with brain herniation. Brain death was diagnosed. This case highlights the possibility of an acute cerebral illness (especially subarachnoid hemorrhage) as an underlying cause of cardiac abnormalities mimicking myocardial ischemia.

Abstract
"Stunned myocardium," characterized by reversible left ventricular dysfunction, was first described via animal models using transient coronary artery occlusion. However, this phenomenon has also been noted with neurologic pathologies and collectively been labeled "neurogenic stunned myocardium" (NSM). Neurogenic stunned myocardium resulting from subarachnoid hemorrhage (SAH) is a challenging pathology due to its diagnostic uncertainty. Traditional diagnostic criteria for NSM after SAH focus on electrocardiographic and echocardiographic abnormalities and troponemia. However, tremendous heterogeneity still exists. Traditional pathophysiological mechanisms for NSM encompassed hypothalamic and myocardial perivascular lesions. More recently, research on pathophysiology has centered on myocardial microvascular dysfunction and genetic polymorphisms. Catecholamine surging as a mechanism has also gained attention with particular focus placed on the role of adrenergic blockade in both the prehospital and acute settings. Management remains largely supportive with case reports acknowledging the utility of inotropes such as dobutamine and milrinone and intra-aortic balloon pump when NSM is accompanied by cardiogenic shock. Neurogenic stunned myocardium that follows SAH can result in many complications such as arrhythmias, pulmonary edema, and prolonged intubation, which can negatively impact long-term recovery from SAH and increase morbidity and mortality. This necessitates the need to accurately diagnose and treat NSM.

Abstract
BACKGROUND Patients with subarachnoid haemorrhage (SAH) frequently develop cardiac complications in the acute phase after the bleeding. Although a number of studies have shown that increased levels of cardiac biomarkers after SAH are associated with a worse short-term prognosis, no prospective, consecutive study has assessed the association between biomarker release and long-term outcome. We aimed to evaluate whether the cardiac biomarkers, high-sensitive troponin T (hsTnT) and N-terminal pro B-type natriuretic peptide (NTproBNP), were associated with poor 1-year neurological outcome and cerebral infarction due to delayed cerebral ischaemia (CI-DCI). METHODS In this single-centre prospective observational study, all consecutive patients admitted to our neurointensive care unit from January 2012 to December 2013 with suspected/verified SAH with an onset of symptoms <72 hours were enrolled. Blood samples for hsTnT and NTproBNP were collected during three consecutive days following admission. Patients were followed-up after 1 year using the Glasgow Outcome Scale Extended (GOSE). Poor neurological outcome was defined as GOSE ≤ 4. RESULTS One hundred and seventy seven patients with suspected SAH were admitted during the study period; 143 fulfilled inclusion criteria and 126 fulfilled follow-up. Forty-one patients had poor 1-year outcome and 18 had CI-DCI. Levels of hsTnT and NTproBNP were higher in patients with poor outcome and CI-DCI. In multivariable logistic regression modelling age, poor neurological admission status, cerebral infarction of any cause and peak hsTnT were independently associated with poor late outcome. Both peak hsTnT and peak NTproBNP were independently associated with CI-DCI. CONCLUSION Increased serum levels of the myocardial damage biomarker hsTnT, when measured early after onset of SAH, are independently associated with poor 1-year outcome. Furthermore, release of both hsTnT and NTproBNP are independently associated with CI-DCI. These findings render further support to the notion that troponin release after SAH is an ominous finding. Future studies should evaluate whether there is a causal relationship between early release of biomarkers of myocardial injury after SAH and neurological sequelae.

An observational study of the association between microalbuminuria and increased N-terminal pro-B-type natriuretic peptide in patients with subarachnoid hemorrhage. J Intensive Care 2015; 3:42. [PMID: 26473035 PMCID: PMC4606477 DOI: 10.1186/s40560-015-0108-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2015] [Accepted: 10/06/2015] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The urinary albumin/creatinine ratio (ACR) is a significant neurologic prognostic predictor in patients with aneurysmal subarachnoid hemorrhage (SAH). B-type natriuretic peptide (BNP) plays an important role in body fluid regulation in patients with SAH. The present study was performed to determine whether ACR was independent predictor for unfavorable neurological outcome and ACR was associated with increased N-terminal pro-BNP (NT-pro-BNP) after SAH. METHODS We studied 61 patients undergoing surgery who were admitted within 48 h after aneurysmal SAH onset between July 2008 and June 2010. Hunt and Hess grade and Fisher grade were recorded at admission. The Glasgow Coma Scale (GCS) score was calculated at admission and daily for seven postoperative days. Arterial blood was sampled at admission and for seven postoperative days to determine the PaO2/FIO2 ratio, C-reactive protein level, troponin I level, and NT-pro-BNP level. Urine was sampled at admission and daily for seven postoperative days to determine ACR and vanillylmandelic acid/creatinine ratio (VMACR). Neurological outcomes were assessed at hospital discharge by using the Glasgow Outcome Scale. Receiver operating characteristic curves were constructed for the predictive variables of unfavorable neurological outcomes, and the area under the curve (AUC) was determined. Multivariate logistic regression analyses were performed for the significant predictors of unfavorable neurological outcomes after SAH. Associations with NT-pro-BNP were evaluated by using the Spearman rank correlation test. RESULTS Of the 61 patients, 24 had unfavorable outcomes. The prevalence rate of microalbuminuria was 85 % (52/61). The highest NT-pro-BNP levels were above the normal range in 57 of 61 patients (93 %). According to the AUC, the Hunt and Hess grade, GCS score, the highest ACR, and highest VMACR were significant predictors of neurological outcome. Multivariate logistic regression analyses showed that the highest ACR and Hunt and Hess grade are independent prognostic predictors of unfavorable neurological outcomes. The highest NT-pro-BNP significantly correlated with the highest troponin I, highest ACR, and VMACR on admission. CONCLUSIONS The highest ACR is an independent prognostic predictor of unfavorable neurological outcomes after SAH. Moreover, plasma NT-pro-BNP elevation may be associated with the development of microalbuminuria.

Abstract
INTRODUCTION Sympathetic nervous system hyperactivity is common after subarachnoid hemorrhage (SAH). We sought to determine whether uncontrolled prolonged heart rate elevation is a risk factor for adverse cardiopulmonary events and poor outcome after SAH. METHODS We prospectively studied 447 SAH patients between March 2006 and April 2012. Prior studies define prolonged elevated heart rate (PEHR) as heart rate >95 beats/min for >12 h. Major adverse cardiopulmonary events were documented according to the predefined criteria. Global outcome at 3 months was assessed with the modified Rankin Scale (mRS). RESULTS 175 (39 %) patients experienced PEHR. Nonwhite race/ethnicity, admission Hunt-Hess grade ≥4, elevated APACHE-2 physiological subscore, and modified Fisher score were significant admission predictors of PEHR, whereas documented pre-hospital beta-blocker use was protective. After controlling for admission Hunt-Hess grade, Cox regression using time-lagged covariates revealed that PEHR onset in the previous 48 h was associated with an increased hazard for delayed cerebral ischemia, myocardial injury, and pulmonary edema. PEHR was associated with 3-month poor outcome (mRS 4-6) after controlling for known predictors. CONCLUSIONS PEHR is associated with major adverse cardiopulmonary events and poor outcome after SAH. Further study is warranted to determine if early sympatholytic therapy targeted at sustained heart rate control can improve outcome after SAH.

Abstract
BACKGROUND Intracranial hemorrhage (ICH) is often associated with cardiac events. Twelve-lead electrocardiography (ECG) and transthoracic echocardiography are essential diagnostic tools for preoperative risk assessment. B-type natriuretic peptide (BNP) is a well-known predictor of cardiac outcome in various clinical settings. This study examined whether BNP levels on admission are associated with in-hospital cardiac events among ICH patients. METHOD This prospective study enrolled 77 ICH patients who were admitted to this hospital for emergency neurosurgery. On admission, BNP levels, 12-lead ECG and transthoracic echocardiography were carried out for all patients. These patients were divided into two groups: Group I included 19 patients (10 men and 9 women) having 24 in-hospital cardiac events (mean age of 57 ± 15 years); Group II included 57 patients (29 men, mean age of 71 ± 11 years) without cardiac events. RESULTS Admission BNP levels of Group I patients were significantly higher than those of Group II patients (683.8 ± 1,043.8 pg/ml vs 168.5 ± 173.5 pg/ml, p = 0.001). In multivariate analysis, BNP levels and T-wave inversion are independent predictors of in-hospital cardiac events. A cutoff value of BNP levels (156.6 pg/ml) predicted in-hospital cardiac events in ICH patients with 80 % sensitivity and 66 % specificity. CONCLUSIONS Serum BNP levels and electrocardiographic T-wave inversion on admission are independent predictors of in-hospital cardiac events in patients with ICH who undergo emergency neurosurgery.

Abstract
Introduction Although aneurysmal subarachnoid hemorrhage (SAH) is often complicated by myocardial injury, whether this neurogenic cardiomyopathy is associated with the modification of cardiac metabolism is unknown. This study sought to explore, by positron emission tomography/computed tomography, the presence of altered cardiac glucose metabolism after SAH. Methods During a 16-month period, 30 SAH acute phase patients underwent myocardial 18 F- fluorodesoxyglucose positron emission tomography (18F-FDGPET), 99mTc-tetrofosmin and 123I-meta-iodobenzylguanidine (123I-mIBG) scintigraphy, respectively, assessing glucose metabolism, cardiac perfusion, and sympathetic innervation. Patients with initial abnormalities were followed monthly for two months for 18F-FDG, and six months later for 123I-mIBG. Results In this SAH population, acute cardiac metabolic disturbance was observed in 83% of patients (n = 25), and sympathetic innervation disturbance affected 90% (n = 27). Myocardial perfusion was normal for all patients. The topography and extent of metabolic defects and innervation abnormalities largely overlapped. Follow-up showed rapid improvement of glucose metabolism in one or two months. Normalization of sympathetic innervation was slower; only 27% of patients (n = 8) exhibited normal 123I-mIBG scintigraphy after six months. Presence of initial altered cardiac metabolism was not associated with more unfavorable cardiac or neurological outcomes. Conclusions These findings support the hypothesis of neurogenic myocardial stunning after SAH. In hemodynamically stable acute phase SAH patients, cardiomyopathy is characterized by diffuse and heterogeneous 18F-FDG and 123I-mIBG uptake defect.

Abstract
BACKGROUND Cardiac abnormalities attributed to adrenergic surge are common after aneurysmal subarachnoid hemorrhage. Prescribed medications that block adrenergic stimulation may suppress the onset of cardiopulmonary compromise in patients after aneurysmal subarachnoid hemorrhage. OBJECTIVES To compare the incidence of early cardiac complications between patients who reported prescribed use of β-blockers and/or angiotensin-converting enzyme inhibitors before aneurysmal subarachnoid hemorrhage and patients who did not. METHODS A retrospective review of 254 adult patients after acute aneurysmal subarachnoid hemorrhage who were enrolled in an existing R01 study. Demographic data and history were obtained from patients'/proxies' reports and charts. Cardiac enzyme levels, 12-lead electrocardiograms, and chest radiographs were obtained on admission. Holter monitoring and echocardiograms were completed as a part of the R01 study. RESULTS Patients reporting prescribed use of angiotensin-converting enzyme inhibitors or β-blockers before aneurysmal subarachnoid hemorrhage had more ventricular and supraventricular ectopy on a Holter report than did patients who did not (P < .05). When age, race, sex, and injury (Fisher grade) were controlled for, patients reporting use of β-blockers were 8 times more likely than others to have occasional to frequent ventricular ectopy (P = .02). CONCLUSION No concrete evidence was found that exposure to adrenergic blockade before aneurysmal subarachnoid hemorrhage provides protection from neurocardiac injury.

Abstract
Abstract
BACKGROUND:
Cardiac dysfunction is a well-known complication of aneurysmal subarachnoid hemorrhage (aSAH). However, the clinical significance of cardiac complications is largely unknown.
OBJECTIVE:
To determine whether cardiac complications are independently related to outcomes and to identify potential predictors associated with these complications.
METHODS:
We extracted all hospitalizations for aSAH from the National Inpatient Sample database for years 2002 to 2009. We used generalized estimating equations to determine whether cardiac complications were associated with the patient outcomes and to evaluate potential predictors of cardiac complications.
RESULTS:
Among 53 713 cases of aSAH, there were 3609 (6.72%) and 151 (0.28%) incidences of cardiac failure (CF) and myocardial infarction (MI), respectively. The overall in-hospital mortality rate was 24.8%, whereas the mortality rate for patients with CF was 34.4% and the mortality rate for patients with MI was 29.8%. Patients who experienced CF were significantly more likely than other patients to die in the hospital (odds ratio: 1.6, 95% confidence interval: 1.47-1.68; P < .001). The difference in mortality rates between MI patients and other patients, however, was not statistically significant. The generalized estimating equation model identified 7 factors that were predictive of CF: age, sex, race, primary payer, diabetes, smoker, and cardiac disease. For MI, the model identified age, race, and primary payer as significant predictors of MI.
CONCLUSION:
Our results suggest that an important association exists between cardiac complications and mortality/morbidity in aSAH patients. aSAH patients with CF appear to have a higher mortality rate, longer hospital length of stay, and higher hospitalization costs compared with those without CF.

Abstract
BACKGROUND AND PURPOSE Cardiac injury is common after subarachnoid hemorrhage (SAH) and is associated with adverse early outcomes, but long-term effects are unknown. The first aim of this study was to compare the long-term rates of death, stroke, and cardiac events in SAH survivors versus a matched population without SAH. The second aim was to quantify the effects of cardiac injury on the outcome rates. METHODS This was a retrospective cohort study of patients with and without non-traumatic SAH. For aim #1, the predictor variable was SAH and the outcome variables were all-cause and cerebrovascular mortality, stroke, cardiac mortality, acute coronary syndrome (ACS), and heart failure (HF) admission. A multivariable Cox proportional hazards analysis was performed. For aim #2, the predictor variables were cardiac injury (elevated serum cardiac enzymes or a diagnosis code for ACS) and dysfunction (pulmonary edema on X-Ray or a diagnosis code for HF). RESULTS Compared with 4,695 members without SAH, the 910 SAH patients had higher rates of all-cause mortality (hazard ratio [HR 2.6], 95% confidence intervals [CI] 2.0-3.4), cerebrovascular mortality (HR 30.6, CI 13.5-69.4), and stroke (HR 10.2, CI 7.5-13.8). Compared with the non-SAH group, the SAH patients with cardiac injury had increased rates of all-cause mortality (HR 5.3, CI 3.0-9.3), cardiac mortality (HR 7.3, CI 1.7-31.6), and heart failure (HR 4.3, CI 1.53-11.88). CONCLUSIONS SAH survivors have increased long-term mortality and stroke rates compared with a matched non-SAH population. SAH-induced cardiac injury is associated with an increased risk of death and heart failure hospitalization.

Abstract
BACKGROUND AND PURPOSE Acute cocaine use has been temporally associated with aneurysmal subarachnoid hemorrhage (aSAH). This study analyzes the impact of cocaine use on patient presentation, complications, and outcomes. METHODS Data of patients admitted with aSAH between 1991 and 2009 were reviewed to determine impact of acute cocaine use (C). These patients were compared with aSAH patients without recent cocaine exposure (NC) in relation to their presentation, complications such as aneurysmal rerupture and delayed cerebral ischemia, and outcomes including hospital mortality and functional outcome. RESULTS Data of 1134 aSAH patients were reviewed; 142 patients (12.5%) had associated cocaine use. Cocaine users were more likely to be younger (mean age: C, 49±11; NC, 53±14; P<0.001). There were no differences in rates of poor-grade Hunt and Hess (4-5); (C, 21%; NC, 26%; P>0.05), associated intraventricular hemorrhage (C, 56%; NC, 51%; P>0.05), or hydrocephalus on admission Head CT (C, 49%; NC, 52%; P>0.05). Aneurysm rerupture incidence was higher among cocaine users (C, 7.7%; NC, 2.7%; P<0.05). The association of cocaine use with higher risk of delayed cerebral ischemia (C, 22%; NC, 16%; P<0.05) was not significant after correcting for other factors. Cocaine users were less likely to survive hospitalization compared with nonusers (mortality: C, 26%; NC, 17%; P<0.05); the adjusted odds of hospital mortality were 2.9 times higher among cocaine users (P<0.001). There were no differences in functional outcomes between the 2 groups. CONCLUSIONS Acute cocaine use was associated with a higher risk of aneurysm rerupture and hospital mortality after aSAH.

Abstract
BACKGROUND Although neurogenic stunned myocardium (NSM) after aneurysmal subarachnoid hemorrhage (SAH) is well described, its clinical significance remains poorly defined. We investigated the influence of left ventricular (LV) dysfunction and cerebral vasospasm on cerebral infarction, serious cardiovascular events, and functional outcome after SAH. METHODS Of the 481 patients enrolled in the University Columbia SAH Outcomes Project between 10/96 and 05/02, we analyzed a subset of 119 patients with at least one echocardiogram, serial transcranial Doppler (TCD) data, and with no prior history of cardiac disease. LV dysfunction was defined as an ejection fraction <40% on echocardiography. Infarction from vasospasm was adjudicated by the study team after comprehensive review of all clinical and imaging data. Functional outcome was assessed at 15 and 90 days with the modified Rankin Scale (mRS). RESULTS Eleven percent of patients had LV dysfunction (N = 13). Younger age, hydrocephalus, and complete filling of the quadrigeminal and fourth ventricles were associated with LV dysfunction (all P < 0.05). Despite a similar frequency of pre-existing hypertension, 0% of patients with LV dysfunction reported taking antihypertensive medication, compared to 35% of those without (P = 0.009). There was a significant association between LV dysfunction and infarction from vasospasm after adjusting for clinical grade, age, and peak TCD flow velocity (P = 0.03). Patients with LV dysfunction also had higher rates of hypotension requiring vasopressors (P = 0.001) and pulmonary edema (P = 0.002). However, there was no association between LV dysfunction and outcome at 14 days after adjustment for established prognostic variables. CONCLUSIONS LV dysfunction after SAH increases the risk of cerebral infarction from vasospasm, hypotension, and pulmonary edema, but with aggressive ICU support does not affect short-term survival or functional outcome. Antihypertensive medication may confer cardioprotection and reduce the risk of catecholamine-mediated injury after SAH.

Abstract
BACKGROUND Myocardial injury after aneurysmal subarachnoid hemorrhage (aSAH) is associated with poor outcomes. Delayed cerebral ischemia (DCI) is also a complication of aSAH. We sought to determine whether (1) DCI could be predicted by demographics, aSAH severity/aneurysm location, or aSAH-associated myocardial injury (SAHMI), and (2) DCI is associated with increased mortality after aSAH. METHODS Prospective longitudinal study of 149 aSAH subjects with definitive DCI evaluation, age 18-75 years, Hunt and Hess (HH) ≥ 3, and/or Fisher ≥ 2, and admitted to the Neurovascular ICU. DCI was defined by the presence of neurological deterioration accompanied by evidence of abnormal cerebral blood flow. RESULTS Subjects were 48% DCI(+) and 52% DCI(-). DCI(+) subjects had more severe aSAH [HH (P = 0.002), Fisher (P = 0.004), admission Glasgow Coma Scale (P = 0.018)]. More DCI(+) subjects had pulmonary congestion than DCI(-) subjects (63 vs. 39%, P = 0.003). On echocardiogram, cardiac output (CO, liters per minute [LPM]) was significantly higher in DCI(+) than in DCI(-) subjects (6 ± 2 vs. 5 ± 1 LPM; P = 0.015). Multivariate analysis identified CO and Fisher grade as independent predictors of DCI (P = 0.02, 0.019). For each 1 LPM increase in CO, the odds of DCI increased by 1.5 (95% CI: 1.1-2.1). Fisher grade 4 increased the odds of DCI by 6.5 compared to Fisher grade 2 (95% CI: 1.6-25.8). After controlling for Fisher grade, CO remained an independent predictor of DCI (P = 0.02). Three-month mortality rate was not significantly different between DCI groups, P = 0.786. CONCLUSION Elevated CO and Fisher grade are predictors of DCI after aSAH. However, prevention of DCI may not decrease mortality.

Abstract
BACKGROUND Patients with aneurysmal subarachnoid hemorrhage experience myocardial injury at the time of rupture, but its effect on functional recovery and disability is unclear. OBJECTIVE To describe the prevalence of myocardial injury, as indicated by high serum levels of cardiac troponin I (≥0.3 ng/mL), within the first 5 days after aneurysmal subarachnoid hemorrhage and the effect of the injury on 3-month functional recovery and disability. METHODS In a prospective longitudinal study, 239 patients with Hunt/Hess grade 3 or greater and/or Fisher grade 2 or greater at admission had serum level of troponin I measured on days 0 to 5. Patients were interviewed at 3 months to evaluate functional recovery (Glasgow Outcome Scale) and functional disability (Modified Rankin Scale). Statistics included χ² analysis, t tests, and binary logistic regression. RESULTS Troponin values were elevated in 33.5% of the patients, and few patients in either group had a history of coronary artery disease (7.4% with troponin levels ≥0.3 ng/mL vs 2.7% with levels <0.3 ng/mL, P = .12). Higher troponin levels were significantly related to age and Hunt/Hess and Fisher grades, but not race, and were significantly associated with poorer functional recovery (P < .001) and more functional disability (P < .001). Even after controls for age, race, and more severe Hunt/Hess grades, higher levels remained a significant predictor of poorer functional recovery (P = .04) and disability (P = .01). CONCLUSION Elevated levels of cardiac troponin I after aneurysmal subarachnoid hemorrhage are common in patients with no cardiac history, are associated with severity of the hemorrhage, and are independently predictive of poorer functional recovery and increased disability.

Abstract
Aneurysmal subarachnoid hemorrhage (aSAH) is a type of hemorrhagic stroke that can cause significant morbidity and mortality. Although guidelines have been published to help direct the care of these patients, there is insufficient quality literature regarding the medical and pharmacological management of patients with aSAH. Treatment is divided into 3 categories: supportive therapy, prevention of complications, and treatment of complications. There are numerous pharmacological therapies that are targeted at prevention and treatment of the neurological and medical complications that may arise. Rebleeding, hydrocephalus, cerebral vasospasm, and seizures are the most common neurological complications while the most common medical complications include hyponatremia, pulmonary edema, cardiac arrhythmias, neurogenic stunned myocardium, fever, anemia, infection, hyperglycemia, and venous thromboembolism. Risk factors, clinical presentation, diagnosis, pathophysiology, as well as initial management, prevention, and treatment of complications will be the focus of this discussion.

Abstract
OBJECTIVE Patients with subarachnoid hemorrhage (SAH) are younger than typical stroke patients. Poor psychosocial outcome after SAH therefore leads to a disproportionately high impact on patients, relatives, and society. Addressing this problem requires an understanding of what causes poor psychosocial outcome. Numerous studies have examined potential predictors but produced conflicting results. We aim to resolve this uncertainty about the potential value of individual predictors by conducting a meta-analysis. This approach allows us to quantitatively combine the findings from all relevant studies to identify promising predictors of psychosocial outcome and determine the strength with which those predictors are associated with measures of psychosocial health. METHODS Psychosocial health was measured by health-related quality of life (HRQOL). We included in our analysis those predictors that were most frequently examined in this context, namely patient age, sex, neurologic state at the time of hospital admission, bleed severity, physical disability, cognitive impairment, and time between ictus and psychosocial assessment. RESULTS Only 1 of the traditional variables, physical disability, had any notable affect on HRQOL. Therefore, the cause of most HRQOL impairment after SAH remains unknown. The situation is even worse for mental HRQOL, an area that is often significantly affected in SAH patients. Here, 90% of the variance remains unexplained by traditional predictors. CONCLUSION Studies need to turn to new factors to account for poor patient outcome.

Abstract
Patients with acute aneurysmal subarachnoid hemorrhage (SAH) often present with more than just neurological compromise. A wide spectrum of complicating cardiopulmonary abnormalities have been documented in patients with acute SAH, presenting additional challenges to the healthcare providers who attempt to treat and stabilize these patients. The patients described in this article presented with both acute aneurysmal SAH and cardiopulmonary compromise. Education and further research on this connection is needed to provide optimal care and outcomes for this vulnerable population. Nurses play a key role in balancing the critical and diverse needs of patients presenting with these symptoms.

Abstract
Left ventricular (LV) dysfunction generally occurs early in the course of subarachnoid hemorrhage (SAH). We evaluated the prognostic value of electrocardiographic (ECG) abnormalities and echocardiographic LV dysfunction evaluated shortly after SAH. We prospectively enrolled 47 SAH patients (62 +/- 14 years, mean +/- SD) who were admitted to the neurosurgical care unit of our institute. Neurological status was rated on the day of admission. Twelve-lead ECG and 2-dimensional echocardiography were recorded 2 +/- 1 day after onset of SAH. ECG abnormalities (pathological Q-wave, ST-segment deviation, T-wave inversion, and QT prolongation) were evaluated and the incidences of global (LV ejection fraction < 50%) and segmental (regional wall motion abnormality [RWMA]) LV dysfunction were measured. During a follow-up period of 44 +/- 23 days, 17 (36%) patients died. ECG abnormalities, LV ejection fraction < 50%, and RWMA were observed in 62%, 11%, and 28% of patients, respectively. Univariate Cox proportional hazards regression analysis revealed that neurological status, rate-corrected QT interval, LV ejection fraction, and RWMA were significant predictors of death. After adjustment for these significant clinical variables, and age and sex, independent predictors of mortality were neurological status and RWMA. RWMA may provide significant prognostic information in patients with SAH.

Abstract
Aneurysmal subarachnoid hemorrhage (SAH) is a dramatic, frequently fatal event. With the incidence of 10 to 15 in 100 000 and a total mortality which even today is 40-50%, it represents a significant problem. Early surgical care for the hemorrhaging aneurysms has, without doubt, an importance in prevention of the rupture, however different series show different results as regards surgical timing and they are very different as regards giving advantage to the early or delayed time of the operation. Our aim was to perceive the results of the treatment in our group of 197 consequently operated patients for ruptured aneurysms with a special attention to the time of operation. This was a prospective clinical study and it was carried out at the Institute for Neurosurgery in Belgrade. Mortality of the operative treatment was a total of 15.74% in the entire group. According to operative intervals from the early to the delayed mortality the range is 35.71%, 22.22%, 11.63% and 8.88% respectively. The results of the treatment are in direct connection with the seriousness of the clinical picture. Being in the group graded from 1-3 decreases the probability of a fatal outcome, and graded from 1-2 decreases probability of morbidity. Early operated patients who in our group included also the most serious cases, life endangered ones, although with higher mortality do not have higher morbidity.

Abstract
BACKGROUND AND PURPOSE Whether cardiac dysfunction contributes to morbidity and mortality after subarachnoid hemorrhage (SAH) remains controversial. The objective of this study was to test the hypothesis that cardiovascular abnormalities are independently related to in-patient mortality after SAH. METHODS This was a prospective cohort study of patients with aneurysmal SAH. Heart rate and blood pressure were measured, a blood sample was obtained, and echocardiography was performed on three study days, starting as soon after admission as possible. The cardiovascular predictor variables were heart rate, systolic blood pressure (SBP), cardiac troponin I (cTi) level, B-type natriuretic peptide (BNP) level, and left ventricular ejection fraction. The primary outcome measure was in-patient mortality. The association between each predictor variable and mortality was quantified by multivariate logistic regression, including relevant covariates and reporting odds ratios (OR) and 95% confidence intervals (CI). RESULTS The study included 300 patients. An initial BNP level greater than 600 pg/mL was markedly associated with death (OR 37.7, p < 0.001). On the third study day (9.1 +/- 4.1 days after SAH symptom onset), a cTi level greater than 0.3 mg/L (OR 7.6, p = 0.002), a heart rate of 100 bpm or greater (OR 4.9, p = 0.009), and a SBP less than 130 mmHg (OR 6.7, p = 0.007) were significantly associated with death. CONCLUSIONS Cardiovascular abnormalities are independent predictors of in-patient mortality after SAH. Though these effects may be explained by a reduction in cerebral perfusion pressure or other mechanisms, further research is required to determine whether or not they are causal in nature.

Abstract
OBJECTIVE To determine the prevalence and the prognostic significance of microalbuminuria in patients after aneurysmal subarachnoid hemorrhage (SAH). DESIGN Prospective and observational clinical study. SETTING Multidisciplinary intensive care unit. PATIENTS Fifty-one consecutive patients who underwent aneurysm clipping or endovascular surgery after SAH; 8 patients who underwent surgical clipping for unruptured intracerebral aneurysm served as control. INTERVENTION None. MEASUREMENTS AND RESULTS General clinical and neurological data were recorded on admission. Urine was collected preoperatively and daily for up to 7 days postoperatively for measuring the urinary microalbumin/creatinine ratio. The Glasgow Coma Scale (GCS) score was also determined on admission and daily for up to 7 days after operation. Neurological outcome was assessed using the Glasgow Outcome Scale (GOS) at 3 months after stroke. The prevalence rates of microalbuminuria were 74.5% in SAH and 37.5% in the control. Among the 51 patients, 25 had unfavorable neurological outcome (GOS 1-3). The areas under the receiver operator characteristic curves showed that the highest urinary microalbumin/creatinine ratio and the lowest GCS score during the first 8 days were the significant predictors of unfavorable neurological outcome. The threshold value, sensitivity, specificity, and likelihood ratio for the highest urinary microalbumin/creatinine ratio were 200 mg/g, 60% [95% confidence interval (CI) 41-79], 96% (95% CI 88-100), and 15.6 (95% CI 9.1-26.7), respectively. CONCLUSIONS This study confirms a high prevalence of microalbuminuria in the SAH patients, and it suggests that the highest urinary microalbumin/creatinine ratio > 200 mg/g during the first 8 days is a significant predictor of unfavorable neurological outcome.

Abstract
BACKGROUND Cardiac complications are frequently encountered by neurointensivists caring for patients with SAH. Our aim was to better characterize the natural history of various cardiac abnormalities in this population. We sought to determine the risk factors for cardiac abnormalities, patient outcome, and impact of treatment type on cardiac abnormalities. METHODS We performed a single center retrospective review of admissions of patients with aneurysmal SAH to the neurosurgical ICU in a large university hospital. Patient demographics, pertinent history, cardiac tests, hospital LOS, intervention type, and discharge outcome were collected. RESULTS Data from 266 patients were available for analysis. Of these patients, 50% (n = 133) demonstrated cardiac abnormalities as indicated by abnormal EKG, ECHO, or troponin I. Only age was determined to be an independent statistically significant predictor of cardiac abnormality (P = .01). There was no difference in mortality between the cardiac abnormality and control groups (P = .33). However, there was increased morbidity in the cardiac abnormality group as demonstrated by worse discharge disposition, in addition to increased length of hospital stay (22.6 vs 17.1 days, P < .01). The incidence of cardiac abnormalities was the same among surgical and endovascular treatment groups. CONCLUSIONS Cardiac abnormalities, including those that meet ACC criteria for MI, are common among patients with SAH. However, in contrast to cardiac events outside the context of SAH, these abnormalities do not increase mortality. They do, however, adversely affect discharge disposition and prolong hospital LOS. The type of aneurysm treatment does not affect the incidence or outcome of cardiac abnormalities.
