Early prediction of cerebral-cardiac syndrome after ischemic stroke: the PANSCAN scale

Stroke-heart syndrome: current progress and future outlook

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.

Post-Ischemic Stroke Cardiovascular Risk Prevention and Management

Cardiac death is the second most common cause of death among patients with acute ischemic stroke (IS), following neurological death resulting directly from acute IS. Risk prediction models and screening tools including electrocardiograms can assess the risk of adverse cardiovascular events after IS. Prolonged heart rate monitoring and early anticoagulation therapy benefit patients with a higher risk of adverse events, especially stroke patients with atrial fibrillation. IS and cardiovascular diseases have similar risk factors which, if optimally managed, may reduce the incidence of recurrent stroke and other major cardiovascular adverse events. Comprehensive risk management emphasizes a healthy lifestyle and medication therapy, especially lipid-lowering, glucose-lowering, and blood pressure-lowering drugs. Although antiplatelet and anticoagulation therapy are preferred to prevent cardiovascular events after IS, a balance between preventing recurrent stroke and secondary bleeding should be maintained. Optimization of early rehabilitation care comprises continuous care across environments thus improving the prognosis of stroke survivors.

S-100β level is closely associated with myocardial work in patients with acute ischemic stroke

BACKGROUND

The more severe the acute stroke is, the more serious myocardial damage is. This study aimed to determine the relationship between myocardial work and S100β, a quantitative biomarker of active cerebral lesions, in patients with acute ischemic stroke (AIS).

METHODS

A total of 63 patients with AIS were examined by myocardial work echocardiography, 4D echocardiography with the measurement of left ventricular (LV) myocardial work, volume and function within 24-48 h of symptom onset, respectively. Their plasma S100β was measured from a peripheral blood sample within 2-6 h of symptom onset.

RESULTS

Patients with elevated S-100β level had significantly increased ratios of peak early diastolic transmitral filling velocity to peak early diastolic lateral mitral annulus tissue velocity(E/e') and global longitudinal strain (GLS), and significantly reduced global work index(GWI) and global constructive work (GCW) compared with those with normal S-100β level (p < 0.05). S-100β positively correlated with E/e'(r = 0.878, p < 0.0001) and GLS (r = 0.511, p = 0.002) but negatively correlated with GWI(r = -0.409, p = 0.034) and GCW(r = -0.353, p = 0.041). S-100β showed an excellent ability to differentiate if a reduced GWI [cut-off value, 120.79 pg/mL; area under receiver operating characteristic curve (AUC), 1.000; sensitivity, 100%; specificity, 100%], GCW (cut-off value, 120.79 pg/mL;AUC,1.000; sensitivity,100%; specificity, 100%) and an increased E/e' (cut-off value, 91.1 pg/mL;AUC,0.913; sensitivity,80%; specificity, 100%) or not, but poor ability to differentiate if an increased GLS(cut-off value, 91.1 pg/mL; AUC,0.576; sensitivity,63.64%; specificity, 83.33%) or not.

CONCLUSION

S-100β level is closely associated with LV function. It is highly competent in determining an impaired myocardial work in patients with AIS.

Relationship between serum HIF-1α and VEGF levels and prognosis in patients with acute cerebral infarction combined with cerebral-cardiac syndrome

Objective

This research was conducted to discuss the recent prognosis of patients with acute cerebral infarction (ACI) combined with cerebral-cardiac syndrome (CCS).

Method

Eighty-seven patients with ACI were selected, which were divided into the ACI group (52 patients) and the CCS group (35 patients) according to whether the CCS was combined, and another 30 health controls were selected as the control group. Serum hypoxia-inducible factor (HIF)-1α and vascular endothelial growth factor (VEGF) levels of subjects in each group at the 1st day, the 3rd day, and the 7th day after admission were measured by enzyme-linked immunosorbent assay. After discharge for 30 days, the National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin Scale (mRS) score were utilized to evaluate the prognosis of patients. The role of serum HIF-1α and VEGF levels in the prognosis of ACI combined with CCS patients was assessed by receiver operating characteristic curve and the binary logistic regression analysis.

Results

Higher serum HIF-1α and VEGF levels were observed in the CCS and ACI groups versus the control group, and the levels of which were even higher in the CCS group in comparison to the ACI group. According to the prognosis of the NIHSS score, fasting blood glucose (FBG), Acute Physiology and Chronic Health Evaluation II score, creatine kinase-MB (CK-MB), and HIF-1α and VEGF levels at the 7th day of admission were higher while Glasgow coma scale (GCS) score was lower in the poor prognosis group than those in the good prognosis group, and the area under the curve (AUC) of serum HIF-1α and VEGF levels was 0.895 (95% confident interval [CI], 0.786-1.000), and 0.855 (95% CI, 0.731-0.980). According to the prognosis of the mRS score, FBG, CK-MB, and HIF-1α and VEGF levels at the 7th day of admission were higher while GCS score was lower in the poor prognosis group than those in the good prognosis group, and the AUC of serum HIF-1α and VEGF levels was 0.850 (95% CI, 0.722-0.979) and 0.901 (95% CI, 0.798-1.000). The results of the binary logistic regression analysis revealed that HIF-1α and VEGF levels may be independent risk factors influencing the prognosis of ACI combined with CCS.

Conclusion

Serum HIF-1α and VEGF have a good predictive value for assessing the recent prognosis of patients with ACI combined with CCS, which could be independent risk factors influencing the prognosis of disease.

A Novel Approach to Assessing the Severity of Acute Stroke and Neurological Deficits in Patients with Acute Ischemic Stroke Using Myocardial Work Echocardiography

BACKGROUND

We aimed to evaluate the feasibility and performance of myocardial work echocardiography in assessing the severity of acute stroke and neurological deficits in patients with acute ischemic stroke.

METHODS

A total of 176 patients were examined by echocardiography within 24-48 hours of symptom onset with the measurement of global and regional myocardial work. The National Institutes of Health Stroke Scale score of each patient was documented.

RESULTS

With the increase of the National Institutes of Health Stroke Scale score, myocardial constructive work or positive work decreased (P 15 or not. The optimal cutoff value was 3.89, with a sensitivity of 100%, a specificity of 93.0%, a positive predictive value of 84.9%, a negative predictive value of 100%, and an accuracy of 95.7%.

CONCLUSION

Noninvasive myocardial work is highly competent in assessing the severity of acute stroke and neurological deficits, which can be used as a powerful supplement to the conventional scoring system.

OUP accepted manuscript

The management of patients with stroke is often multidisciplinary, involving various specialties and healthcare professionals. Given the common shared risk factors for stroke and cardiovascular disease, input may also be required from the cardiovascular teams, as well as patient caregivers and next-of-kin. Ultimately, the patient is central to all this, requiring a coordinated and uniform approach to the priorities of post-stroke management, which can be consistently implemented by different multidisciplinary healthcare professionals, as part of the patient ‘journey’ or ‘patient pathway,’ supported by appropriate education and tele-medicine approaches. All these aspects would ultimately aid delivery of care and improve patient (and caregiver) engagement and empowerment. Given the need to address the multidisciplinary approach to holistic or integrated care of patients with heart disease and stroke, the European Society of Cardiology Council on Stroke convened a Task Force, with the remit to propose a consensus on Integrated care management for optimizing the management of stroke and associated heart disease. The present position paper summarizes the available evidence and proposes consensus statements that may help to define evidence gaps and simple practical approaches to assist in everyday clinical practice. A post-stroke ABC pathway is proposed, as a more holistic approach to integrated stroke care, would include three pillars of management:

A: Appropriate Antithrombotic therapy.

B: Better functional and psychological status.

C: Cardiovascular risk factors and Comorbidity optimization (including lifestyle changes).

Perfect storm along the neuro-cardiac axis: stroke complicated by acute biventricular dysfunction-Takotsubo syndrome or neurogenic stress cardiomyopathy?

Acute biventricular dysfunction complicating acute ischaemic stroke poses diagnostic and therapeutic challenges with respect to anticoagulation and short-term and long-term prognosis. We present the uncommon case of an elderly patient presenting with this clinical scenario, who made a full recovery on conservative therapy. Management strategies are discussed and the emerging topic of neuro-cardiac syndromes, namely neurogenic stress cardiomyopathy as distinct from Takotsubo syndrome, is explored.
