BACKGROUND: Randomized data comparing outcomes of transcatheter aortic valve replacement (TAVR) with surgery in low-surgical risk patients at time points beyond 2 years is limited. This presents an unknown for physicians striving to educate patients as part of a shared decision-making process.
OBJECTIVES: The authors evaluated 3-year clinical and echocardiographic outcomes from the Evolut Low Risk trial.
METHODS: Low-risk patients were randomized to TAVR with a self-expanding, supra-annular valve or surgery. The primary endpoint of all-cause mortality or disabling stroke and several secondary endpoints were assessed at 3 years.
RESULTS: There were 1,414 attempted implantations (730 TAVR; 684 surgery). Patients …
Targeting Metabolic Alterations Associated With Smooth Muscle Α-Actin Pathogenic Variant Attenuates Moyamoya-Like Cerebrovascular Disease, Anita Kaw
Dissertations and Theses (Open Access)
Heterozygous pathogenic variants in ACTA2, encoding smooth muscle α-actin (α-SMA), predispose to thoracic aortic aneurysms and dissections. De novo missense variants disrupting ACTA2 arginine 179 (p.Arg179) cause a multisystemic disease termed smooth muscle dysfunction syndrome (SMDS), which is characterized by early onset thoracic aortic disease and moyamoya disease-like (MMD) cerebrovascular disease. The MMD-like cerebrovascular disease in SMDS patients is marked by bilateral steno-occlusive lesions in the distal internal carotid arteries (ICAs) and their branches. To study the molecular mechanisms that underlie the ACTA2 p.Arg179 variants, a smooth muscle-specific Cre-lox knock-in mouse model of the heterozygous Acta2 R179C variant, termed …

BACKGROUND: The occurrence of atrial fibrillation, circadian fluctuation in blood pressure, and oxygen desaturation at night is likely associated with the pathophysiology of wake-up stroke. Whether patients who experience wake-up strokes are candidates for thrombolysis treatment is a serious dilemma. The aim is to investigate the association between risk factors and wake-up stroke and to determine variations that are associated with the pathophysiology of wake-up stroke.
METHODS: Five major electronic databases were searched using a fitted search strategy to identify relevant studies. Odds ratios with 95% CIs were used to calculate estimates, and the Quality Assessment for Diagnostic Accuracy Studies-2 …

BACKGROUND: Most vascular events after stroke may be prevented by modifying vascular risk factors through medical and behavioral interventions. Stroke literacy-an understanding of stroke symptoms, risk factors, and treatment-likely contributes to vascular risk factor control and in turn stroke recurrence risk. Stroke literacy is the lowest among adults belonging to racial and ethnic minority populations in the United States. Video-based interventions targeting stroke literacy may help acute stroke survivors understand stroke and subsequently reduce the risk of stroke recurrence. However, the failure of prior stroke literacy interventions may be due in part to the fact that the interventions were not …

OBJECTIVE: Stroke is a global public health burden, and therefore it is critical to identify modifiable risk factors to reduce stroke incidence and improve outcomes. Depression is such a risk factor; however, the association between preexisting depression and stroke outcomes, such as independent ambulation, is not well studied, especially among racial-ethnic minority groups. To address this gap in the literature, effects of preexisting depression on ambulatory status at hospital discharge after stroke were evaluated among individuals participating in the racially and ethnically diverse Florida-Puerto Rico Collaboration to Reduce Stroke Disparities project.
METHODS: Data were analyzed from a total of 42,031 …

Stroke is the second leading cause of death and a major cause of disability worldwide, and biological sex is an important determining factor in stroke incidence and pathology. From childhood through adulthood, men have a higher incidence of stroke compared with women. Abundant research has confirmed the beneficial effects of estrogen in experimental ischemic stroke but genetic factors such as the X-chromosome complement can also play an important role in determining sex differences in stroke. Autophagy is a self-degrading cellular process orchestrated by multiple core proteins, which leads to the engulfment of cytoplasmic material and degradation of cargo after autophagy …

The impact of sex on pathophysiological processes, clinical presentation, treatment options, as well as outcomes of degenerative aortic stenosis remain poorly understood. Female patients are well represented in transfemoral aortic valve implantation (TAVI) trials and appear to derive favorable outcomes with TAVI. However, higher incidences of major bleeding, vascular complications, and stroke have been reported in women following TAVI. The anatomical characteristics and pathophysiological features of aortic stenosis in women might guide a tailored planning of the percutaneous approach. We highlight whether a sex-based TAVI management strategy might impact on clinical outcomes. This review aimed to evaluate the impact of …

Background
Recent genetic discoveries in stroke have unleashed the potential of using genetic information for risk prediction and health interventions aimed at disease prevention. We sought to estimate the lifetime risk of stroke (LTRS) by levels of genetic risk and to investigate whether optimal cardiovascular health can offset the negative impact of high genetic risk on lifetime risk of stroke.
Methods and Results
Study participants were 11 568 middle‐aged adults (56% women, 23% Black adults), who were free of stroke at baseline and were followed up for a median of 28 years. The remaining LTRS was estimated according to levels …

Hypercoagulable disorders are often the culprit for repeated strokes in young patients, with or without other comorbidities
Medications typically used for stroke prophylaxis:
- Warfarin
- Aspirin
- Direct Oral Anticoagulants (DOACs)
Warfarin is the preferred method of anticoagulation for stroke prophylaxis in patients with hypercoagulable disorders
A deficiency of protein S increases the risk of pro coagulation due to a relative deficiency of anticoagulants.
Patients with protein S deficiency tend to have recurrent venous thromboses and pulmonary emboli

Stroke is the second leading cause of mortality globally with higher burden and younger age in low-middle income countries (LMICs) than high-income countries (HICs). However, it is unclear to what extent differences in healthcare access and quality (HAQ) and prevalence of risk factors between LMICs and HICs contribute to younger age of stroke in LMICs. In this systematic review, we conducted meta-analysis of 67 articles and compared the mean age of stroke between LMICs and HICs, before and after adjusting for HAQ index. We also compared the prevalence of main stroke risk factors between HICs and LMICs. The unadjusted mean …

Stroke Prevention In Patients With Non-Valvular Atrial Fibrillation: The Watchman Device Versus Warfarin, Emma Delaney
Stroke Prevention In Patients With Non-Valvular Atrial Fibrillation: The Watchman Device Versus Warfarin, Emma Delaney
Theses and Graduate Projects
Atrial fibrillation is a common heart arrhythmia that leads to an increased risk of stroke. Warfarin was the original anticoagulant that would be used as the treatment for atrial fibrillation. However, there are people who have contraindications to anticoagulation or are a high fall risk and shouldn’t be on Warfarin. The Watchman Device was originally designed in 2005 as a way to close the left atrial appendage where clots are usually present with atrial fibrillation. The watchman may be a superior way to help reduce the risk of stroke compared to the traditional use of Warfarin. Purpose: Literature review …

In stroke care, the extent of irreversible brain injury, termed infarct core, plays a key role in determining eligibility for acute treatments, such as intravenous thrombolysis and endovascular reperfusion therapies. Many of the pivotal randomized clinical trials testing those therapies used MRI Diffusion-Weighted Imaging (DWI) or CT Perfusion (CTP) to define infarct core. Unfortunately, these modalities are not available 24/7 outside of large stroke centers. As such, there is a need for accurate infarct core determination using faster and more widely available imaging modalities including Non-Contrast CT (NCCT) and CT Angiography (CTA). Prior studies have suggested that CTA provides improved …

Journal of the Saudi Heart Association
Atrial fibrillation (AF) is a common and prevalent form of arrhythmia. It is associated with various morbidities with stroke being the major hazard. Since AF is often reported to be asymptomatic, many individuals remain unaware of their condition and may not receive the requisite treatment. Hence, screening for AF has gained substantial attention recently. Growing advancement in technology has paved way for numerous approaches for AF screening using medical-prescribed devices as well as consumer electronic devices. However, there still lies scope for large-scale randomized trials which would explore additional aspects associated with AF. This review very concisely summarizes AF, screening, …

In the United States, approximately 800,000 individuals experience a stroke every year
Nearly 25% of strokes are recurrent
Cryptogenic strokes, or those with unknown causes after testing, make up a significant portion of ischemic strokes, as many as 32%
Retrograde thromboembolic events originating from the proximal descending thoracic aorta should be considered as a potential etiology in cryptogenic strokes
The appropriate management of embolic events from aortic atheroma needs further research
Here, we present a case of a 55-year-old male who had recurrent cryptogenic strokes whose origin was discovered to stem from retrograde embolic phenomena from atheroma located within the …

BACKGROUND: The association between systemic hypertension and cerebrovascular disease is well documented. However, the impact of pulmonary hypertension (PH) on acute ischemic stroke outcomes is unknown despite PH being recognized as a risk factor for acute ischemic stroke. We aimed to determine the association between PH and adverse in-hospital outcomes after acute ischemic stroke, as well as whether there are sex differences in this association. METHODS AND RESULTS: Acute ischemic stroke admissions from the US National Inpatient Sample between October 2015 and December 2017 were included. The relationship between PH and outcomes (mortality, prolonged hospitalization >4 days, and routine home …

Physician Assistant Capstones, 2020-current
Objective: To determine if the WATCHMAN device is as efficacious as warfarin for stroke prevention in patients with non-valvular atrial fibrillation (NVAF) using a systematic review. Methods: Pubmed and Google Scholar databases were used to evaluate clinical trials using the search terms atrial fibrillation, watchman, warfarin, and stroke prevention. Results: Three studies met inclusion criteria, with 2 being randomized control trials (RCT), and 1 being a prospective cohort study. Reddy et al found that after 3.8 years of follow-up, patients with percutaneous closure of Left atrial appendage (LAA) met criteria for both non-inferiority and superiority, compared with warfarin for preventing …

Cardiovascular disease remains a major contributor to morbidity and mortality in the US and elsewhere, and stroke is a leading cause of disability worldwide. Despite recent success in diminishing stroke incidence in the general US population, in parallel there is now a concerning propensity for strokes to happen at younger ages. Specifically, the incidence of stroke for US adults 20-44 years of age increased from 17 per 100,000 US adults in 1993 to 28 per 100,000 in 2015. Occurrence of strokes in young adults is particularly problematic as these patients are often affected by physical disability, depression, cognitive impairment and …
