AIMS: Complications from catheter ablation for atrial fibrillation (AF) are well described. Changing aspects of AF ablation including patient populations referred, institutional experience, and emerging catheter and pharmacological options may impact complication rates. We assessed procedural complication trends in AF ablation patients from 2003-2015 to identify what factors affect adverse event rates. METHODS AND RESULTS: We evaluated consecutively enrolled patients undergoing initial AF ablation from 2003 through 2015...

Characterization of carotid plaque composition, more specifically the amount of lipid core, fibrous tissue, and calcified tissue, is an important task for the identification of plaques that are prone to rupture, and thus for early risk estima-tion of cardiovascular and cerebrovascular events. Due to its low costs and wide availability, carotid ultrasound has the potential to become the modality of choice for plaque characterization in clinical practice. However, its significant image noise, coupled with the small size of the plaques and their complex appearance, makes it difficult for automated techniques to discriminate be-tween the different plaque constituents...

BACKGROUND: Emergency ambulance dispatches (EAD) are a novel outcome for evaluating the public health impacts of air pollution. We assessed the relationships between ambient particulate matter (PM) from all sources, PM from landscape fire smoke (LFS), and EADs likely to be associated with cardiorespiratory problems in the Sydney greater metropolitan region for an 11-year period from 2004 to 2015. METHODS: EAD codes are assigned at the time of the call to emergency services using standard computer assisted algorithms...

Hypertension (HTN) is one of the most common emerging disease in developing countries. It alters endothelial cell structure and function, resulting in several diseases, such as cardiovascular disease, peripheral vasculopathy, cerebrovascular disease and nephropathy. Although much progress has been made in researching HTN in recent years, early diagnosis and treatment of HTN are not yet satisfactory, and progression control/treatment is still poor. MicroRNAs are well-known regulators of the physiological and developmental processes of HTN...

OBJECTIVE: To test the hypothesis that more cardiovascular emergencies occur at low rather than at high temperatures under moderate climatic conditions. METHODS: This was a prospective observational study performed in a prehospital setting. Data from the Emergency Medical Service in Hamburg (Germany) and from the local weather station were evaluated over a 5-year period. Temperature data were matched with the associated rescue mission data. Lowess-Regression analysis was performed to assess the relationship between the temperature and the frequency of individual cardiovascular emergencies...

Stroke and related cerebrovascular diseases are a major cause of mortality and disability. Even at standard-field-strengths (1.5T), MRI is by far the most sensitive imaging technique to detect acute brain infarctions and to characterize incidental cerebrovascular lesions, such as white matter hyperintensities, lacunes and microbleeds. Arterial time-of-flight (TOF) MR angiography (MRA) can depict luminal narrowing or occlusion of the major brain feeding arteries, and this without the need for contrast administration...

Fast-track surgery has been widely implemented and allows such immediate extubation as in the operating room(OR). We retrospectively investigated the effect of routine ultra-fast-track(UFT) surgery extubating in the OR in patients undergoing cardiovascular operations. Among 333 consecutive patients, 224 (67.3%)were extubated in the OR. Five patients were re-intubated, but none were because of heart or respiratory failure. Independent predictors for failure of OR extubation were preoperative renal failure, pre-existent cerebrovascular disease, emergency surgery, and prolonged operation and/or cardiopulmonary bypass times...

OBJECTIVES: The use of short-term mechanical circulatory support (MCS) has increased in the treatment of refractory cardiogenic shock (RCS). Percutaneous short-term MCS technology has emerged rapidly; however, limitations in flow and durability remain. We therefore investigated a minimally invasive surgical approach using an external ventricular assist device (VAD) and extracorporeal membrane oxygenation (ECMO) in patients with RCS. METHODS: Twenty-five patients underwent minimally invasive external VAD insertion with a magnetically levitated centrifugal pump for various causes of cardiogenic shock between April 2010 and May 2016...

COL4A1 and COL4A2 are extracellular matrix proteins that form heterotrimers and are present in nearly all basement membranes in every organ. In the past decade, COL4A1 and COL4A2 mutations have been identified to cause a multi-system disorder for which penetrance and severity of constituent phenotypes can greatly vary. Here, we compare the outcomes of more than 100 mutations identified in patients and data from a murine allelic series to explore the presence of genotype-phenotype correlations - many of which are shared among other types of collagen...

White matter disease in the brain increases with age and cardiovascular disease, emerging in midlife, and these associations may be influenced by both genetic and environmental factors. We examined the frequency, distribution, and heritability of abnormal white matter and its association with hypertension in 395 middle-aged male twins (61.9 ± 2.6 years) from the Vietnam Era Twin Study of Aging, 67% of whom were hypertensive. A multi-channel segmentation approach estimated abnormal regions within the white matter...

Cerebrovascular (CV) dysfunction is emerging as a critical component of Alzheimer's disease (AD), including altered CV coverage. Angiogenic growth factors (AGFs) are key for controlling CV coverage, especially during disease pathology. Therefore, evaluating the effects of AGFs in vivo can provide important information on the role of CV coverage in AD. We recently demonstrated that epidermal growth factor (EGF) prevents amyloid-beta (Aβ)-induced damage to brain endothelial cells in vitro. Here, our goal was to assess the protective effects of EGF on cognition, CV coverage and Aβ levels using an AD-Tg model that incorporates CV relevant AD risk factors...

Off-pump coronary artery bypass grafting (OPCAB) in patients with acute myocardial infarction (AMI) is difficult because of circulatory deterioration during displacement of the heart. At our institution, we performed minimally circulatory-assisted on-pump beating coronary artery bypass grafting (MICAB) in these patients. During MICAB, support flow was controlled at a minimal level to maintain a systemic blood pressure of approximately 100 mm Hg and a pulmonary arterial systolic pressure of <30 mm Hg, providing optimal pulsatile circulation for end-organ perfusion and prevention of heart congestion...

INTRODUCTION: The treatment of giant intracranial aneurysms is one of the most challenging cerebrovascular problems of neurosurgery. We report the rupture of a giant, lobulated, and almost completely thrombosed middle cerebral artery (MCA) aneurysm that is the ninth such report in the literature. We also investigated additional solutions used in the treatment of this patient. CASE PRESENTATION: A 58-year-old man had been admitted with headache 8 years previously (in 2005), and a giant MCA aneurysm was detected...

Alzheimer's disease (AD) is a neurodegenerative disease, in which an accumulation of toxic amyloid beta in the brain precedes the emergence of clinical symptoms. AD spectrum consists of presymptomatic, early symptomatic, and symptomatic phase of dementia. At present, no pharmacotherapy exists to modify or reverse a course of AD, and only symptomatic treatments are available. Many elderly patients, diagnosed with multiple medical conditions (such as cardiovascular diseases, Type 2 diabetes mellitus, and cerebrovascular diseases) are at increased risk of the development of mild cognitive impairment (MCI), AD, and vascular dementia...

Arterial spin labeling (ASL) is a magnetic resonance (MR) imaging technique used to assess cerebral blood flow noninvasively by magnetically labeling inflowing blood. In this article, the main labeling techniques, notably pulsed and pseudocontinuous ASL, as well as emerging clinical applications will be reviewed. In dementia, the pattern of hypoperfusion on ASL images closely matches the established patterns of hypometabolism on fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET) images due to the close coupling of perfusion and metabolism in the brain...
