Abstract
Stroke can lead to cardiac complications such as arrhythmia, myocardial injury, and cardiac dysfunction, collectively termed stroke-heart syndrome (SHS). These cardiac alterations typically peak within 72 h of stroke onset and can have long-term effects on cardiac function. Post-stroke cardiac complications seriously affect prognosis and are the second most frequent cause of death in patients with stroke. Although traditional vascular risk factors contribute to SHS, other potential mechanisms indirectly induced by stroke have also been recognized. Accumulating clinical and experimental evidence has emphasized the role of central autonomic network disorders and inflammation as key pathophysiological mechanisms of SHS. Therefore, an assessment of post-stroke cardiac dysautonomia is necessary. Currently, the development of treatment strategies for SHS is a vital but challenging task. Identifying potential key mediators and signaling pathways of SHS is essential for developing therapeutic targets. Therapies targeting pathophysiological mechanisms may be promising. Remote ischemic conditioning exerts protective effects through humoral, nerve, and immune-inflammatory regulatory mechanisms, potentially preventing the development of SHS. In the future, well-designed trials are required to verify its clinical efficacy. This comprehensive review provides valuable insights for future research.

Abstract
Elevated high-sensitivity cardiac troponin (hs-cTn) levels should be expected in about half of all patients with acute ischemic stroke (AIS). Since those patients are at risk of increased morbidity and mortality, often attributable to cardiac causes, an adequate work-up of the underlying etiology is required. This can only be achieved by a team of cardiologists and neurologists. Since underlying causes of hs-cTn elevation in AIS patients are diverse, often atypical or silent in their clinical presentation and some, such as an accompanying myocardial infarction, can be acutely life-threatening, the work-up should follow a standardized clinical algorithm. The vast majority of hs-cTn elevations are caused by non-ischemic myocardial injury associated with AIS. This work presents a practice-oriented approach to differential diagnosis with the update of the Mannheim clinical algorithm for acute ischemic stroke and troponin elevation.

Abstract
The emergence of acute ischemic stroke (AIS) induced cardiovascular dysfunctions as a bidirectional interaction has gained paramount importance in understanding the intricate relationship between the brain and heart. Post AIS, the ensuing cardiovascular dysfunctions encompass a spectrum of complications, including heart attack, congestive heart failure, systolic or diastolic dysfunction, arrhythmias, electrocardiographic anomalies, hemodynamic instability, cardiac arrest, among others, all of which are correlated with adverse outcomes and mortality. Mounting evidence underscores the intimate crosstalk between the heart and the brain, facilitated by intricate physiological and neurohumoral complex networks. The primary pathophysiological mechanisms contributing to these severe cardiac complications involve the hypothalamic-pituitary-adrenal (HPA) axis, sympathetic and parasympathetic hyperactivity, immune and inflammatory responses, and gut dysbiosis, collectively shaping the stroke-related brain-heart axis. Ongoing research endeavors are concentrated on devising strategies to prevent AIS-induced cardiovascular dysfunctions. Notably, labetalol, nicardipine, and nitroprusside are recommended for hypertension control, while β-blockers are employed to avert chronic remodeling and address arrhythmias. However, despite these therapeutic interventions, therapeutic targets remain elusive, necessitating further investigations into this complex challenge. This review aims to delineate the state-of-the-art pathophysiological mechanisms in AIS through preclinical and clinical research, unraveling their intricate interplay within the brain-heart axis, and offering pragmatic suggestions for managing AIS-induced cardiovascular dysfunctions.

Abstract
BACKGROUND Acute ischemic stroke (AIS) complicating an acute myocardial infarction (AMI) is not uncommon, but can severely worsen the clinical prognosis. This study aimed to investigate whether remote ischemic conditioning (RIC) could provide clinical benefits to patients with AIS complicating AMI. METHODS Subjects with AIS complicating AMI were recruited in this double-blind, randomized, controlled trial; assigned to the RIC and sham groups; and respectively underwent twice daily RIC and sham RIC for 2 weeks. All subjects received standard medical therapy. The primary endpoint was the rate of major adverse cardiac and cerebrovascular events (MACCEs) within 3 months after enrollment. MACCEs comprise of death from all causes, unstable anginas, AMI, acute ischemic strokes, and transient ischemic attacks. RESULTS Eighty subjects were randomly assigned; 37 patients in the RIC group and 40 patients in the sham-RIC group completed the 3-month follow-up and were included in the final analysis. Both RIC and sham RIC procedures were well tolerated. At 3-month follow-up, 11 subjects (29.7%) in the RIC group experienced MACCEs compared to 21 (52.5%) in the sham group (hazard ratio [HR], 0.396; 95% confidence interval, 0.187-0.838; adjusted p < 0.05). Six subjects (16.2%) in the RIC group had died at the 3-month follow up, significantly lower than the 15 (37.5%) deaths in the sham group (adjusted HR 0.333; 95% CI 0.126-0.881; p = 0.027). Seventeen subjects (45.9%) in the RIC group and 6 subjects (15.0%) in the sham group achieved functional independence (mRS score ≤ 2) at 3-month follow-up (adjusted OR 12.75; 95% CI 2.104-77.21; p = 0.006). CONCLUSIONS Among patients with acute ischemic stroke complicating acute myocardial infarction, treatment with remote ischemic conditioning decreased the major adverse cardiac and cerebrovascular events and improved functional outcomes at 90 days.

Abstract
Cardiovascular and cerebrovascular diseases are frequently interconnected due to underlying pathology involving atherosclerosis and thromboembolism. The aim of this study was to investigate the impact of clinical interactions among cardiovascular and cerebrovascular diseases on patient outcomes using a large-scale nationwide claims-based dataset. Cardiovascular diseases were defined as myocardial infarction, heart failure, atrial fibrillation, and aortic dissection. Cerebrovascular diseases were defined as cerebral infarction, intracerebral hemorrhage, and subarachnoid hemorrhage. This retrospective study included 2,736,986 inpatient records (1,800,255 patients) at 911 hospitals from 2015 to 2016 from Japanese registry of all cardiac and vascular disease-diagnostic procedure combination dataset. Interactions among comorbidities and complications, rehospitalization, and clinical outcomes including in-hospital mortality were investigated. Among hospitalization records that involved cardiovascular disease, 5.9% (32,686 records) had cerebrovascular disease as a comorbidity and 2.1% (11,362 records) included an incident cerebrovascular complication after hospitalization. Cerebrovascular disease as a comorbidity or complication was associated with higher in-hospital mortality than no cerebrovascular disease (adjusted odds ratio (OR) [95% confidence interval]: 1.10 [1.06–1.14], 2.02 [1.91–2.13], respectively). Among 367,904 hospitalization records that involved cerebrovascular disease, 17.7% (63,647 records) had cardiovascular disease listed as comorbidity and 3.3% (11,834 records) as a complication. Only cardiovascular disease as a complication was associated with higher in-hospital mortality (adjusted OR [95% confidence interval]: 1.29 [1.22–1.37]). In addition, in-hospital mortality during rehospitalization due to the other disease was significantly higher than mortality during the hospitalization due to the first disease. In conclusion, substantial associations were observed between cardiovascular and cerebrovascular disease in a large-scale nationwide claims-based dataset; these associations had a significant impact on clinical outcomes. More intensive prevention and management of cardiovascular and cerebrovascular disease might be crucial.

Acute Myocardial Infarction after Intravenous Thrombolysis for Acute Ischemic Stroke: Case Series and Systematic Review. J Stroke Cerebrovasc Dis 2021; 31:106244. [PMID: 34915306 DOI: 10.1016/j.jstrokecerebrovasdis.2021.106244] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Revised: 11/19/2021] [Accepted: 11/23/2021] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND AND OBJECTIVES Intravenous thrombolysis (IV-rtPA) has been suggested as a potential cause of myocardial infarction (MI) after acute ischemic stroke (AIS), with randomized clinical trials showing a higher number of cardiac events within the thrombolysis group. We assessed the prevalence and MI mechanisms after IV-rtPA for AIS. METHODS Retrospective review of consecutive AIS patients admitted to six stroke units and systematic literature review searching for AIS patients who suffered a MI less than 24 h after IV-rtPA. In those with available coronary angiography, MI etiology was defined as atherosclerotic or embolic. Patients' characteristics were compared between groups. RESULTS Fifty-two patients were included. Thirty-two patients (61.5%) derived from hospital cases, after reviewing 6958 patients treated with IV-rtPA [0.5% (95% CI 0.38-0.54) of total hospital cases]. After coronary angiography (n = 25, 48.1%), 14 (54%) patients were considered to have an atherosclerotic MI, and 11 (46%) due to coronary embolism. Patients with an embolic MI more frequently had a cardioembolic AIS (72.7% vs 28.6%; p-value = 0.047) and an intracardiac thrombus (27.3% vs 0.0%; p-value = 0.044). Although not statistically significant, patients with an embolic MI had apparent lower time intervals between starting IV-rtPA infusion and MI occurrence [2 h (0.2-3.0) vs 3 h (1.0-15.0); p-value = 0.134]. CONCLUSIONS MI within the first 24 h after IV-rtPA for AIS is an infrequent event, and more frequently non-embolic. However, the prevalence of embolic MI was superior to what is found in the general population with MI. There was an association between the pathophysiology of AIS and MI. The low number of events and publication bias may have limited our conclusions.

Abstract
Over 1.5 million deaths worldwide are caused by neurocardiogenic syndromes. Furthermore, the consequences of deleterious brain-heart interactions are not limited to fatal complications. Cardiac arrhythmias, heart failure, and nonfatal coronary syndromes are also common. The brain-heart axis is implicated in post-stroke cardiovascular complications known as the stroke-heart syndrome, sudden cardiac death, and Takotsubo syndrome, among other neurocardiogenic syndromes. Multiple pathophysiological mechanisms with the potential to be targeted with novel therapies have been identified in the last decade. In the present state-of-the-art review, we describe recent advances in the understanding of anatomical and functional aspects of the brain-heart axis, cardiovascular complications after stroke, and a comprehensive pathophysiological model of stroke-induced cardiac injury.

Clin Neurol Neurosurg 2020; 198:106159. [PMID: 32829200 DOI: 10.1016/j.clineuro.2020.106159] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Revised: 08/13/2020] [Accepted: 08/13/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND AND AIMS Myocardial infarction complicating acute ischemic stroke (IS) is associated with high mortality, but evidence guiding the acute management is scarce. In particular, data on the risk of intracerebral hemorrhage (ICH) due to early cardiac catheterization including the peri-procedural application of antithrombotic drugs in patients with acute ischemic stroke are limited. Here, we aimed to evaluate the incidence and patient characteristics of ICH after cardiac catheterization in acute stroke patients to help to govern the risk of intracranial bleeding versus the benefits of myocardial reperfusion via cardiac catheterization. METHODS We screened a consecutive cohort of n = 126 patients with acute ischemic stroke (IS) who underwent cardiac catheterization during the same hospital stay at a large German neurovascular center (LMU Munich). Eventually, we identified n = 42 patients with cardiac catheterization after acute stroke. N = 22/42 patients did not receive neuroimaging post cardiac catheterization and were discharged without any new neurological deficits, n = 20/42 had neuroimaging after cardiac catheterization and were included for final analysis. RESULTS Cardiac catheterization was performed within a median of 3,6 days after ischemic stroke (No-ICH 7,3 days (IQR, 3,8-16,2) vs. ICH 1,1 days (IQR, 0,8-74,6), p = 0,40), One patient showed new neurological deficits after cardiac procedures (n = 1/42, 2,4 %). New or progressive ICH was ultimately found in 15 % (3/20) of cases. They were classified as HT1, PH1 and PH2 according to ECASS II criteria, respectively. With regards to the coronary catheterization, 85 % of all patients undergoing catheterization ultimately received percutaneous cardiac intervention. ICH was not significantly associated with any of the independent variables. Intrahospital death due to either ischemic stroke, ICH or cardiovascular events did not occur. CONCLUSION The incidence of ICH in ischemic stroke followed by early cardiac catheterization and application of antithrombotic drugs was comparable to studies reporting on the incidence of ICH in ischemic stroke patients without catheterization. This study's results strengthen the hypothesis that in presence of both, acute myocardial infarction and acute ischemic stroke, the general risk for ICH is not prohibitive of cardiac catheterization.

Abstract
IMPORTANCE Studies of acute myocardial infarction (AMI) occurring outside the hospital have informed approaches to addressing risk, treatment, and patient outcomes. Similar insights for in-hospital AMI are lacking. OBJECTIVE To determine the incidence, risk factors, and outcomes associated with in-hospital AMI. DESIGN, SETTING, AND PARTICIPANTS Cohort, nested case-control, and matched cohort study of patients hospitalized in US Veterans Health Administration facilities between July 2007 and September 2009. The incidence of in-hospital AMI was determined from a complete cohort of in-hospital AMI relative to the total number of inpatient admissions. From the in-hospital AMI cohort, detailed medical record review was performed on 687 cases and 687 individually matched controls. Risk factors and outcomes associated with in-hospital AMI were determined from matched comparison of in-hospital AMI cases to hospitalized controls. EXPOSURES Candidate risk factors for in-hospital AMI included characteristics at the time of admission and in-hospital variables prior to the index date. MAIN OUTCOMES AND MEASURES In the determination of the incidence and risk factors associated with in-hospital AMI, the outcome of interest was in-hospital AMI. All-cause mortality was the main outcome of interest following in-hospital AMI. RESULTS A total of 5556 patients with in-hospital AMI (mean [SD] age, 73 [10] years; 5456 [98.2%] male) were identified among 1.3 million admissions, with an incidence of 4.27 in-hospital AMI events per 1000 admissions. Independent risk factors associated with in-hospital AMI included intensive care unit setting, history of coronary artery disease, heart rate greater than 100 beats/min, hemoglobin level less than 8 g/dL, and white blood cell count 14 000/μL or greater. Compared with the matched control group, mortality was significantly higher for patients with in-hospital AMI (in-hospital mortality, 26.4% vs 4.2%; 30-day mortality, 33.0% vs 10.0%; 1-year mortality, 59.2% vs 34.4%). CONCLUSIONS AND RELEVANCE In-hospital AMI was common and associated with common cardiovascular risk factors and markers of acute illness. Patient outcomes following in-hospital AMI were poor, with 1-year mortality approaching 60%. Further study of in-hospital AMI may yield opportunities to reduce in-hospital AMI risk and improve patient outcomes.

Abstract
INTRODUCTION Controversies remain on whether post-stroke complications represent an independent predictor of poor outcome or just a reflection of stroke severity. We aimed to identify which post-stroke complications have the highest impact on in-hospital mortality by using machine learning techniques. Secondary aim was identification of patient's subgroups in which complications have the highest impact. PATIENTS AND METHODS Registro Nacional de Ictus de la Sociedad Española de Neurología is a stroke registry from 42 centers from the Spanish Neurological Society. Data from ischemic stroke patients were used to build a random forest by combining 500 classification and regression trees, to weight up the impact of baseline characteristics and post-stroke complications on in-hospital mortality. With the selected variables, a logistic regression analysis was performed to test for interactions. RESULTS 12,227 ischemic stroke patients were included. In-hospital mortality was 5.9% and median hospital stay was 7(4-10) days. Stroke severity [National Institutes of Health Stroke Scale > 10, OR = 5.54(4.55-6.99)], brain edema [OR = 18.93(14.65-24.46)], respiratory infections [OR = 3.67(3.02-4.45)] and age [OR = 2.50(2.07-3.03) for >77 years] had the highest impact on in-hospital mortality in random forest, being independently associated with in-hospital mortality. Complications have higher odds ratios in patients with baseline National Institutes of Health Stroke Scale <10. DISCUSSION Our study identified brain edema and respiratory infections as independent predictors of in-hospital mortality, rather than just markers of more severe strokes. Moreover, its impact was higher in less severe strokes, despite lower frequency. CONCLUSION Brain edema and respiratory infections were the complications with a greater impact on in-hospital mortality, with the highest impact in patients with mild strokes. Further efforts on the prediction of these complications could improve stroke outcome.

Abstract
Stroke remains one of the main causes of death and disability worldwide. The challenge of predicting stroke outcome has been traditionally assessed from a general point of view, where baseline non-modifiable factors such as age or stroke severity are considered the most relevant factors. However, after stroke occurrence, some specific complications such as hemorrhagic transformations or post stroke infections, which lead to a poor outcome, could be developed. An early prediction or identification of these circumstances, based on predictive models including clinical information, could be useful for physicians to individualize and improve stroke care. Furthermore, the addition of biological information such as blood biomarkers or genetic polymorphisms over these predictive models could improve their prognostic value. In this review, we focus on describing the different post-stroke complications that have an impact in short and long-term outcome across different time points in its natural history and on the clinical-biological information that might be useful in their prediction.

Abstract
OBJECTIVE Following an acute stroke, there is a high risk of recurrence. However, the leading cause of mortality following a stroke is due to coronary artery disease (CAD) and myocardial infarction (MI) but that risk has not been robustly quantified. We sought to reliably quantify the risk of ischaemic heart disease (IHD) in patients presenting with acute ischaemic stroke (AIS) in the absence of a known cardiac history. SETTING A meta-analysis study. PubMed, MEDLINE, EMBASE and Google Scholar were searched for potential studies up to October 2015. Included studies reported an acute cerebral ischaemic event and followed for CAD or MI within 1 year in patients without known IHD. Using arcsine transformed proportions for meta-analysis, studies were combined using a generic inverse variance random-effects model to calculate the pooled standardised mean difference and 95% CIs. These were interpreted as the percentage prevalence of CAD or incidence of MI following AIS. RESULTS 17 studies with 4869 patients with AIS demonstrated a mean average of asymptomatic CAD in 52%. Anatomical methods of CAD detection revealed a prevalence of asymptomatic ≥ 50% coronary stenosis in 32% (95% CI 19% to 47%; p<0.00001). 8 studies with 47229 patients with ischaemic stroke revealed an overall risk of MI in the year following stroke of 3% (95% CI 1% to 5%; p<0.00001) despite the absence of any cardiac history. CONCLUSIONS One-third of patients with ischaemic stroke with no cardiac history have more than 50% coronary stenosis and 3% are at risk of developing MI within a year. Our findings provide a reliable quantitative measure of the risk of IHD following AIS in patients with no cardiac history.

Abstract
BACKGROUND Cardiac events in patients with acute stroke are frequent. Urgent PCI in myocardial infarction is crucial to improve outcome. However, the situation is complex as intracranial hemorrhage is a frequent complication of stroke but antithrombotic medication is indispensable during and after PCI. Therefore in this study, we aimed to investigate the safety of percutaneous coronary intervention (PCI) in patients hospitalized with acute ischemic stroke and concomitant acute coronary syndrome (ACS). METHODS AND RESULTS In a single-center, case-series study we investigated 80 patients hospitalized with acute stroke/transient ischemic attack (TIA) and concomitant ACS undergoing coronary angiography. Patients with subsequent PCI were compared to patients with medical treatment alone. The primary end point was the composite of death, recurrent MI, coronary re-intervention, recurrent stroke or bleeding during 1-year follow-up. The secondary end point consisted of the components of the primary end point. Age, gender and cardiovascular risk factors did not differ between groups. However, severity of initial stroke and coronary artery disease was higher in the PCI group. Accordingly, antiplatelet medication with aspirin and clopidogrel was prescribed more frequently in the PCI group. Nevertheless, during 1-year follow-up, the primary end point did not differ between groups [38 vs. 50 %, odds ratio (OR) 1.7, CI 0.69-4.07, P = 0.23]. Intracranial hemorrhage was even numerically lower in patients undergoing PCI (5 vs. 3 %, OR 0.4, CI 0.04-5.6, P = 0.46). CONCLUSIONS The primary and secondary end points were not enhanced in patients undergoing PCI. Therefore PCI is safe in patients with stroke/TIA and concomitant ACS.

Abstract
Background Whether acupuncture protects stroke patients from acute myocardial infarction (AMI) has not been studied previously. The purpose of this study was to investigate the risk of AMI among stroke patients receiving acupuncture treatment. Methods Taiwan’s National Health Insurance Research Database was used to conduct a retrospective cohort study of 23475 stroke patients aged 40–79 years receiving acupuncture treatment and 46950 propensity score-matched stroke patients not receiving acupuncture treatment who served as controls from 2000 to 2004. Both stroke cohorts were followed until the end of 2009 and were adjusted for immortal time to measure the incidence and adjusted hazard ratios (HRs) with 95 % confidence intervals (CIs) for new-onset AMI in multivariate Cox proportional hazard models. Results Stroke patients who received acupuncture treatment (9.2 per 1000 person-years) exhibited a lower incidence of AMI compared with those who did not receive acupuncture treatment (10.8 per 1000 person-years), with an HR of 0.86 (95 % CI, 0.80–0.93) after adjusting for age, sex, low income, coexisting medical conditions and medications. The relationship between acupuncture treatment and AMI risk was investigated in female stroke patients (HR, 0.85; 95 % CI, 0.76–0.95), male stroke patients (HR, 0.87; 95 % CI, 0.80–0.95), patients from 50 to 59 years of age (HR, 0.75; 95 % CI, 0.63–0.90), patients from 60 to 69 years of age (HR, 0.85; 95 % CI, 0.75–0.95), patients suffering from ischemic stroke (HR, 0.87; 95 % CI, 0.79–0.95), and patients suffering from hemorrhagic stroke (HR, 0.62; 95 % CI, 0.44–0.88). Conclusions We raised the possibility that acupuncture may be effective in lowering the risk of AMI in stroke patients aged 50–69 in this study, which was limited by a lack of information regarding stroke severity and acupuncture points. Our results suggest that prospective randomized trials are needed to establish the efficacy of acupuncture in preventing AMI.

Abstract
PURPOSE To investigate the risk of stroke and acute myocardial infarction (AMI) in patients with incident central retinal artery occlusion (CRAO). DESIGN A self-controlled case series (SCCS) study. PARTICIPANTS Patients with incident CRAO from the entire Korean population of 48 million individuals. METHODS We used the Korean national claim database (2007-2011) for analyses. After identifying patients with incident CRAO, the relative incidence rate ratios (IRRs) for stroke and AMI in risk periods were measured in these patients using a SCCS method. MAIN OUTCOME MEASURES The IRRs of stroke and AMI by risk periods. RESULTS Of 1655 patients with incident CRAO in 2009-2010, 165 had stroke/AMI (ischemic stroke in 139, hemorrhagic stroke in 13, and AMI in 15) in the observation period spanning 365 days before and after the occurrence of CRAO. The IRR of stroke/AMI 1 to 30 days after CRAO occurrence significantly increased (14.0; 95% confidence interval [CI], 8.90-22.00); the IRR peaked during the 1 to 7 days after CRAO occurrence (44.51; 95% CI, 27.07-73.20), and the increased risk was present for the first 30 days. The IRR of stroke/AMI also significantly increased 1 to 30 days (6.82; 95% CI, 4.01-11.60) and 31 to 90 days (2.86; 95% CI, 1.66-4.93) before CRAO occurrence. Subanalysis for only ischemic stroke showed similar, magnified IRRs in the risk periods compared with all events. The IRRs were not significantly different between sexes or age groups (<65 vs. ≥65 years). CONCLUSIONS Patients with incident CRAO are at increased risk of ischemic stroke just after CRAO occurrence, and the risk is particularly increased during the first week immediately after the CRAO occurrence. The results suggest that patients with incident CRAO require immediate neurologic evaluation and preventive treatment to reduce mortality and morbidity.

Abstract
Stroke and especially its complications are a leading cause of death. Despite reduced morbidity in some developed countries, mortality in stroke patients is still high worldwide. In the past decades, treatment of acute stroke has focused on early intervention, such as revascularization and cerebral edema prevention. However, long-term clinical observations indicate that poststroke pneumonia, cardiovascular complications, and vascular embolism are the major reasons for the increased death rate after stroke. Few evidence-based data are available currently to guide the management of these complications. Thus, systematic studies of these adverse events are essential and urgent to improve survival after stroke.

Abstract
Objectives To determine the association between myocardial infarction (AMI) and clinical outcome in patients with primary admissions diagnosis of acute cerebral ischemia (ACI) in the US. Methods Data from Nationwide Inpatient Sample (NIS) was queried from 2002–2011 for inpatient admissions of patients with a primary diagnosis of ACI with and without AMI using International Classification of Diseases, Ninth Revision, Clinical Modification coding (ICD-9). A multivariate stepwise regression analysis was performed to assess the correlation between identifiable risk factors and clinical outcomes. Results During 10 years the NIS recorded 886,094 ACI admissions with 17,526 diagnoses of AMI (1.98%). The overall cumulative mortality of cohort was 5.65%. In-hospital mortality was associated with AMI (aOR 3.68; 95% CI 3.49–3.88, p≤0.0001), rTPA administration (aOR 2.39 CI, 2.11–2.71, p<0.0001), older age (aOR 1.03, 95% CI, 1.03–1.03, P<0.0001) and women (aOR 1.06, 95% CI 1.03–1.08, P<0.0001). Overall, mortality risk declined over the course of study; from 20.46% in 2002 to 11.8% in 2011 (OR 0.96, 95% CI 0.95–0.96, P<0.0001). Survival analysis demonstrated divergence between the AMI and non-AMI sub-groups over the course of study (log-rank p<0.0001). Conclusion Our study demonstrates that although the prevalence of AMI in patients hospitalized with primary diagnosis of ACI is low, it negatively impacts survival. Considering the high clinical burden of AMI on mortality of ACI patients, a high quality monitoring in the event of cardiac events should be maintained in this patient cohort. Whether prompt diagnosis and treatment of associated cardiovascular diseases may improve outcome, deserves further study.

Abstract
BACKGROUND Patients with transient ischemic attack (TIA) and stroke have an increased risk for subsequent cardiac events including myocardial infarction (MI), which might be associated with a worse clinical outcome. Rapid identification of stroke patients at higher risk for MI might foster intensified cardiac monitoring or certain therapeutic strategies. However, information regarding acute MI as a complication of stroke in the very acute phase is limited. Moreover, there are no systematic data on the occurrence of MI following intracerebral hematoma. We thus aimed to assess the frequency, clinical characteristics and short-term outcome of patients suffering from acute MI in the stroke unit setting. METHODS We analyzed 46,603 patients from 32 Austrian stroke units enrolled in the prospective Austrian Stroke Unit Registry because of TIA/acute stroke over a 6-year period (January 1, 2007 to January 13, 2013). A total of 41,619 patients (89.3%) had been treated for TIA/ischemic stroke and 4,984 (10.7%) for primary intracerebral hemorrhage (ICH). Acute MI was defined according to clinical evaluation, ECG findings and laboratory assessments. Patients with evidence for MI preceding the cerebrovascular event were not considered. RESULTS Overall, 421 patients (1%) with TIA/ischemic stroke and 17 patients (0.3%) with ICH suffered from MI during stroke unit treatment for a median duration of 3 days. Patients with TIA/ischemic stroke and MI were significantly older, clinically more severely affected and had more frequently vascular risk factors, atrial fibrillation and previous MI. Total anterior circulation and left hemispheric stroke syndromes were more often observed in MI patients. Patients with MI not only suffered from worse short-term outcome including a higher mortality (14.5 vs. 2%; p < 0.001) at stroke unit discharge, but also acquired more stroke complications like progressive stroke and pneumonia. Multivariate analyses identified previous MI and stroke severity at admission (according to the National Institutes of Health and Stroke Scale score) as factors independently associated with the occurrence of MI on the stroke unit. CONCLUSIONS While quite rare in the acute phase after stroke, MI is associated with a poor short-term outcome including a higher mortality. Patients with previous MI and severe stroke syndromes appear to be at particular risk for MI as an early complication in the stroke unit setting. Further studies are needed to determine whether increased vigilance and prolonged (cardiac) monitoring or certain therapeutic approaches could improve the outcome in these high-risk patients.

Abstract
Cardiac disease, in particular coronary artery disease, is the leading cause of mortality in developed nations. Strokes can complicate cardiac disease - either as result of left ventricular dysfunction and associated thrombus formation or of therapy for the cardiac disease. Antiplatelet drugs and anticoagulants routinely used to treat cardiac disease increase the risk for hemorrhagic stroke.

Abstract
Background and purpose Data on cardiac complications and their precipitants after intracerebral hemorrhage are scarce. We examined the frequency and risk factors for serious in-hospital cardiac events in a large cohort of consecutive intracerebral hemorrhage patients. Methods A retrospective chart review of 1013 consecutive patients with nontraumatic intracerebral hemorrhage treated at the Helsinki University Central Hospital (2005–2010). We excluded patients with intraparenchymal hematoma related to sub-arachnoid hemorrhage or intracerebral hemorrhage because of fibrinolytic therapies for acute ischemic stroke or myocardial infarction. Serious in-hospital cardiac event was defined as any of in-hospital poststroke acute myocardial infarction, ventricular fibrillation or tachycardia, moderate to serious acute heart failure, or cardiac death. Results Among the 948 patients included, ≥1 serious in-hospital cardiac event occurred in 39 (4·1%) patients after a median delay of two-days from stroke onset (acute myocardial infarction in three patients, ventricular fibrillation or tachycardia in three patients, acute heart failure in 36 patients, and cardiac death in three patients). Hospital stay was longer in patients with serious in-hospital cardiac event than in those without (median 12, interquartile range 7–19 vs. 8, 3–14; P = 0·001), with no difference in in-hospital mortality (23·1% vs. 24·3%; P = 0·86). In multivariable logistic regression analysis adjusted for age, gender, and diabetes, atrial fibrillation during hospitalization (odds ratio 6·68 for new-onset atrial fibrillation, 95% confidence interval 2·11–21·18; 4·46 for old atrial fibrillation, 2·08–9·56), and history of myocardial infarction (3·20, 1·18–8·66) were independently associated with serious in-hospital cardiac events. Conclusions After intracerebral hemorrhage, 4% of patients suffer an acute serious cardiac complication. Those with history of myocardial infarction or in-hospital atrial fibrillation are at greater risk for such events.

Abstract
The clinical importance of cardiovascular consequences resulting from cerebral injury has long been recognized. However, interactions between the brain and the cardiovascular system remain poorly defined and their importance for the management of patients suffering from acute brain injury is largely underestimated. This should have profound consequences on treatment strategies during anaesthesia and intensive cares of these patients, taking into account not only brain perfusion, but also cardiovascular optimisation. This report summarizes the main data available regarding the cardiovascular consequences of brain death, traumatic brain injury, stroke and epilepsy.

Abstract
Background and Purpose—
The common medical complications after ischemic stroke are associated with increased mortality and resource use.
Method—
The study population consisted of 1 150 336 adult hospitalizations with ischemic stroke as a primary diagnosis included in the 1998 to 2007 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project. Multiple logistic regression analyses were used to examine changes between 1998 to 1999 and 2006 to 2007 in the prevalence of acute myocardial infarction, pneumonia, deep venous thrombosis, pulmonary embolism, or urinary tract infection, in-hospital mortality, and length of stay.
Results—
In 2006 to 2007, the prevalence of hospitalizations with a secondary diagnosis of acute myocardial infarction, pneumonia, deep venous thrombosis, pulmonary embolism, and urinary tract infection was 1.6%, 2.9%, 0.8%, 0.3%, and 10.1%, respectively. The adjusted ORs for a hospitalization in 2006 to 2007 complicated by acute myocardial infarction, deep venous thrombosis, pulmonary embolism, or urinary tract infection, using 1998 to 1999 as the referent, were 1.39, 1.68, 2.39, and 1.18, respectively. The odds of pneumonia did not change significantly between 1998 to 1999 and 2006 to 2007. In-hospital mortality was significantly lower in 2006 to 2007 than in 1998 to 1999. Despite the overall length of stay decreasing significantly from 1998 to 1999 to 2006 to 2007, it remained the same for hospitalizations with acute myocardial infarction, pneumonia, deep vein thrombosis, and pulmonary embolism.
Conclusion—
Although in-hospital mortality decreased over the study period, 4 of the 5 complications were more common in 2006 to 2007 than they were 8 years earlier with the largest increase observed for deep venous thrombosis and pulmonary embolism.
