Abstract
Aim: After acute ischemic cerebrovascular accident (CVA), identification of high-risk patients, appropriate cardiac follow-up and detection of arrhythmias are important to prevent cardiac morbidity and mortality. The aim of our study is to determine the underlying etiology and the frequency of arrhythmia by holter electrocardiography (ECG) in patients referred to the cardiology clinic due to acute ischemic CVA.
Materials and Methods: A total of 135 consecutive patients who had acute ischemic CVA between January 2019 and June 2021 and whose basal ECG was sinus rhythm were included in the study. This study was a retrospective cross-sectional study.
Results: The mean age of the patients was 72.02±11.02 years, the mean systolic arterial blood pressure was 138.84±20.45 mmHg, and the mean heart rate was 81.63±16.18 beats/min. The most common comorbid diseases were HT (n=67, %49.6) and CAD (n=55, %40.7). 5.9% of patients had prosthetic heart valve and 5.2% had permanent pacemaker. Intracardiac thrombus was detected in 5 (3.7%) patients. The mean left ventricular ejection fraction was 54.4±9.1%. In carotid doppler ultrasonography (USG), 27 (20%) patients had unilateral and 17 (12.6%) bilateral severe carotid arterial stenosis. The most common arrhythmias detected on holter ECG were ventricular extrasystole (n=34, 25.2%) and paroxysmal atrial fibrillation (n=31, 23%). In addition, non-sustained ventricular tachycardia was detected in 6 (4.4%) patients.
Conclusion: Determining the underlying etiology in patients with acute ischemic CVA is important for the treatment of the disease. The incidence of arrhythmia that should be treated in this patient group is too high to be ignored.

Cerebellar Stroke in a COVID-19 Infected Patient. a Case Report. ACTA ACUST UNITED AC 2021; 7:130-135. [PMID: 34722914 PMCID: PMC8519368 DOI: 10.2478/jccm-2021-0004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2020] [Accepted: 01/10/2021] [Indexed: 11/30/2022]
Abstract
Background Recent studies have reported that COVID-19 infected patients with stroke, who were often in the older age group, had a higher incidence of vascular risk factors, and more severe infection related respiratory symptoms. These observations provided little evidence to suggest that COVID-19 infection is a potential causative factor for stroke. This report describes a young patient with a cerebellar stroke secondary to COVID-19 infection. Case presentation A 45-year old male presented at a hospital, reporting a two-day history of headache, vertigo, persistent vomiting, and unsteady gait. Physical examination revealed gaze-evoked nystagmus on extraocular movement testing, left-sided dysmetria and dysdiadochokinesia. He was diagnosed with a left cerebellar stroke. An external ventricular drain was inserted, and sub-occipital craniectomy was performed to manage the effects of elevated intracranial pressure due to the extent of oedema secondary to the infarct. He also underwent screening for the COVID-19 infection, which was positive on SARS-COV-2 polymerase chain reaction testing of his endotracheal aspirate. Blood and cerebrospinal fluid samples were negative. After the surgery, the patient developed atrial fibrillation and had prolonged vomiting symptoms, but these resolved eventually with symptomatic treatment. He was started on aspirin and statin therapy, but anticoagulation was withheld due to bleeding concerns. The external ventricular drain was removed nine days after the surgery. He continued with active rehabilitation. Conclusions Young patients with COVID-19 infection may be more susceptible to stroke, even in the absence of risk factors. Standard treatment with aspirin and statins remains essential in the management of COVID-19 related stroke. Anticoagulation for secondary prevention in those with atrial fibrillation should not be routine and has to be carefully evaluated for its benefits compared to the potential harms of increased bleeding associated with COVID-19 infection.

Abstract
Background: Paroxysmal atrial fibrillation (PAF) or flutter is prevalent among patients with cryptogenic stroke. The goal of this study was to investigate the feasibility of incorporating a fast-track, long term continuous heart monitoring (LTCM) program within a stroke clinic. Method: We designed and implemented a fast-track LTCM program in our stroke clinics. The instrument that we used for the study was the ZioXT® device from IRhythm™ Technologies. To implement the program, all clinic support staff received training on the skin preparation and proper placement of the device. We prospectively followed every patient who had a request from one of our inpatient or outpatient stroke or neurology providers to receive LTCM. We recorded patients' demographics, the LTCM indication, as well as related quality measures including same-visit placement, wearing time, analyzable time, LTCM application to the preliminary finding time, as well as patients' out of pocket cost. Results: Out of 501 patients included in the study, 467 (93.2%) patients (mean age 65.9 ± 13; men: 48%) received LTCM; and 92.5% of the patients had the diagnosis of stroke or TIA. 93.7% of patients received their LTCM during the same outpatient visit in the stroke clinic. The mean wearing time for LTCM was 12.1 days (out of 14 days). The average analyzable time among our patients was 95.0%. Eighteen (3.9%, 95%CI: 2.4-6.0) patients had at least one episode of PAF that was sustained for more than 30 s. The rate of PAF was 5.9% (95% CI: 3.5-9.2) among patients with the diagnosis of stroke. Out of 467 patients, 392 (84%) had an out-of-pocket cost of < $100. Conclusion: It is feasible to implement a fast-track cardiac monitoring as part of a stroke clinic with proper training of stroke providers, clinic staff, and support from a cardiology team.

Abstract
Knowledge gaps exist in how we implement aerobic exercise programs during the early phases post-stroke. Therefore, the objective of this review was to provide evidence-based guidelines for pre-participation screening, mobilization, and aerobic exercise training in the hyper-acute and acute phases post-stroke. In reviewing the literature to determine safe timelines of when to initiate exercise and mobilization we considered the following factors: arterial blood pressure dysregulation, cardiac complications, blood-brain barrier disruption, hemorrhagic stroke transformation, and ischemic penumbra viability. These stroke-related impairments could intensify with inappropriate mobilization/aerobic exercise, hence we deemed the integrity of cerebral autoregulation to be an essential physiological consideration to protect the brain when progressing exercise intensity. Pre-participation screening criteria are proposed and countermeasures to protect the brain from potentially adverse circulatory effects before, during, and following mobilization/exercise sessions are introduced. For example, prolonged periods of standing and static postures before and after mobilization/aerobic exercise may elicit blood pooling and/or trigger coagulation cascades and/or cerebral hypoperfusion. Countermeasures such as avoiding prolonged standing or incorporating periodic lower limb movement to activate the venous muscle pump could counteract blood pooling after an exercise session, minimize activation of the coagulation cascade, and mitigate potential cerebral hypoperfusion. We discuss patient safety in light of the complex nature of stroke presentations (i.e., type, severity, and etiology), medical history, comorbidities such as diabetes, cardiac manifestations, medications, and complications such as anemia and dehydration. The guidelines are easily incorporated into the care model, are low-risk, and use minimal resources. These and other strategies represent opportunities for improving the safety of the activity regimen offered to those in the early phases post-stroke. The timeline for initiating and progressing exercise/mobilization parameters are contingent on recovery stages both from neurobiological and cardiovascular perspectives, which to this point have not been specifically considered in practice. This review includes tailored exercise and mobilization prescription strategies and precautions that are not resource intensive and prioritize safety in stroke recovery.
