Prevalence and Prognostic Features of ECG Abnormalities in Acute Stroke
Conclusions About 4 in 5 acute stroke patients in this African cohort had evidence of a baseline ECG abnormality, but presence of any atrial enlargement was the only independent ECG predictor of death or disability.

Systemic Complications Following Aneurysmal Subarachnoid Hemorrhage
AbstractMany systemic complications follow aneurysmal subarachnoid hemorrhage and are primarily due to sympathetic nervous system activation. These complications play an important role in the overall outcome of patients. The purpose of this review is to provide an update on the diagnosis, pathophysiology, and management of systemic complications specifically associated with aneurysmal subarachnoid hemorrhage. Special focus has been made on systemic complications that occur more frequently in patients with aneurysmal subarachnoid hemorrhage compared to other stroke subtypes and in the neurocritical care patient population. ...

Electrocardiographic differentiation between takotsubo syndrome and acute myocardial infarction
It is crucial to differentiate between acute myocardial infarction (AMI), particularly of the ST-segment elevation (STE) AMI variety, and takotsubo syndrome (TTS), in order as swiftly as possible to implement thrombolytic therapy and/or percutaneous coronary interventions for the former. Also the potential benefits accrued by such an early diagnostic differentiation has a bearing on the urgency and timing of coronary arteriography, and the use of antiplatelet/anticoagulation regimen, particularly in patients “with multiple comorbidities such as those presenting after physical stressors such as subarachnoid hemorrhage or ...

Electrocardiographic Abnormalities Predict Adverse Clinical Outcomes in Patients with Subarachnoid Hemorrhage
We conducted a retrospective cohort study of a large sample to assess whether electrocardiographic (ECG) abnormalities are independently associated with the occurrence of neurogenic pulmonary edema (NPE), delayed cerebral ischemia (DCI), and in-hospital death after nontraumatic subarachnoid hemorrhage (SAH).

The prognostic value of QT dispersion in patients with acute neurological events without known cardiac disease

Validation of a novel index of hemorrhage using a lower body negative pressure shock model.
CONCLUSION: iHAT measures both the reduction in preload and the parabolic heart rate increase due to the linear decrease in stroke volume. iHAT was able to detect a progressive central volume loss in a model of hemorrhage in healthy volunteers undergoing LBNP. A rising trend in iHAT can be a useful marker for progressive volume loss during moderate to severe bleeding. PMID: 26756378 [PubMed - as supplied by publisher]

Cardiac Arrhythmias and Abnormal Electrocardiograms After Acute Stroke.
Abstract Cardiac arrhythmias and electrocardiogram (ECG) abnormalities occur frequently but are often underrecognized after strokes. Acute ischemic and hemorrhagic strokes in some particular area of brain can disrupt central autonomic control of the heart, precipitating cardiac arrhythmias, ECG abnormalities, myocardial injury and sometimes sudden death. Identification of high-risk patients after acute stroke is important to arrange appropriate cardiac monitoring and effective management of arrhythmias, and to prevent cardiac morbidity and mortality. More studies are needed to better clarify pathogenesis, localiza...

Brain-heart axis - Review Article.
Authors: Manea MM, Comsa M, Minca A, Dragos D, Popa C Abstract UNLABELLED: There has been a large confirmation over the last decades that stroke may produce cardiac changes (echocardiographic, electrocardiographic, enzymatic). In ischemic stroke, systolic dysfunction is associated with a high risk of mortality during hospitalization. A recent study demonstrated that cardiac diastolic dysfunction could also accompany acute stroke besides the systolic dysfunction already pointed out by previous studies, being a predictive marker of acute cerebrovascular events. Increased sympathetic activity is contributory, inducing...

Electrocardiograph abnormalities in intracerebral hemorrhage
This study investigated the prevalence and type of electrocardiography (ECG) abnormalities, and their possible association with the clinical/radiological findings in 118 consecutive patients with non-traumatic, non-neoplastic intracerebral hemorrhage (ICH). ECG frequently demonstrates abnormalities in patients with ischemic stroke and subarachnoid hemorrhage, but little is known of ECG changes in ICH patients. Clinical and radiological information was retrospectively reviewed. ECG recordings that were obtained within 24hours of the initial hemorrhage were analyzed. Sixty-six patients (56%) had one or more ECG abnormalities...

Is tree loss associated with cardiovascular-disease risk in the Women's Health Initiative? A natural experiment.
Abstract Data from the Women's Health Initiative were used to quantify the relationship between the loss of trees to an invasive forest pest-the emerald ash borer-and cardiovascular disease. We estimated a semi-parametric Cox proportional hazards model of time to cardiovascular disease, adjusting for confounders. We defined the incidence of cardiovascular disease as acute myocardial infarction requiring overnight hospitalization, silent MI determined from serial electrocardiograms, ischemic or hemorrhagic stroke, or death from coronary heart disease. Women living in a county infested with emerald ash borer had an ...

Intracranial Hemorrhage and Deep T Wave Inversions
A woman in her 70s with a medical history significant for atrial fibrillation and cardioembolic stroke who was receiving long-term anticoagulation therapy with warfarin (international normalized ratio, 2.3) presented to an outside facility with sudden onset of nausea and vertigo. Her mental status declined and she was unable to protect her airway, prompting intubation. Computed tomographic scan (CT) at that time was negative for any intracranial pathologic findings. On arrival to our facility, the patient remained lethargic and unresponsive; therefore, a second noncontrast head CT was performed, which showed no evidence fo...

Electrocardiographic Monitoring for Detecting Atrial Fibrillation After Ischemic Stroke or Transient Ischemic Attack: Systematic Review and Meta-Analysis Original Articles
Conclusions— Longer duration of electrocardiographic monitoring after cryptogenic stroke is associated with a greater detection of AF. Future investigation is needed to determine the optimal duration of long-term monitoring.

Prevalence and impact on outcome of electrocardiographic early repolarization patterns among stroke patients: a prospective observational study
Conclusions ER is frequently found among patients with acute cerebrovascular events and is more prevalent in patients with hemorrhagic compared to ischemic events. Our study yields no evidence that ER is associated with worse outcome or mortality after stroke.

Out-of-Hospital Cardiac Arrest From Brain Cause: Epidemiology, Clinical Features, and Outcome in a Multicenter Cohort*
Conclusions: Presentation of cerebrovascular event complicated with out-of-hospital cardiac arrest may mimic coronary etiology, but several clinical elements may help to identify brain causes. Even if survival is null, the high proportion of brain deaths provides opportunity for organ donation.

P-wave dispersion and left atrial indices as predictors of paroxysmal atrial fibrillation in patients with non hemorrhagic cerebrovascular strokes and transient ischemic attacks
Conclusion PAF is a possible etiology of patients with ischemic cerebrovascular accidents patients even in those who had normal sinus rhythm on admission. Pmax ⩾125mm, Pdis ⩾40mm, and LAVI⩾24 are highly significant predictors of PAF with PPV of 99%, 96% and 78%, respectively, sensitivity of 98%, 94% and 89%, respectively, specificity 96%, 93% and 75%, respectively and AUC of 0.99, 0.98 and 0.87, respectively.
