A Comparison of Protocols for Simulating Hemorrhage in Humans: Step vs. Ramp Lower Body Negative Pressure
(2019-03-05)Lower body negative pressure (LBNP) elicits central hypovolemia, and has been used to characterize the cardiovascular and cerebrovascular responses to simulated hemorrhage in humans. LBNP protocols traditionally employ a ... -
Are Spontaneous Low Frequency Oscillations in Arterial Pressure and Cerebral Blood Flow Associated with the Protection of Cerebral Tissue Oxygenation during Simulated Hemorrhage?
(2019-03-05)Introduction: Prior studies have independently demonstrated that subjects with higher tolerance to simulated hemorrhage elicited by lower body negative pressure (LBNP) exhibit maintenance of cerebral tissue oxygenation, ... -
Beyond Magnetic Resonance Angiography in Anomalous Aortic Origin of the Coronary Arteries: Additive Value of Late Gadolinium Enhancement
(2019-03-05)Purpose: Anomalous aortic origin of the coronary arteries (AAOCA) is a common cause of sudden cardiac death (SCD) in young athletes. The prevalence, pathophysiology, and optimal method of risk stratifying AAOCA are unknown. ... -
Contribution of K+/Cl- Cotransporters in AT1aR Dependent GABAa Inhibition in the MnPO Following Chronic Intermittent Hypoxia
(2019-03-05)Purpose: Chronic intermittent hypoxia (CIH) is an animal model that simulates the hypoxemia seen in obstructive sleep apnea (OSA). Rats exposed to CIH exhibit an increase in blood pressure during periods of normoxia, similar ... -
Development of Predictive Model for Detection of Sleep Apnea in Underrepresented Minorities
(2019-03-05)Purpose: Obstructive Sleep Apnea (OSA) is a sleep disorder that is caused by recurrent upper airway closure and is highly associated with hypertension. OSA is also known to be underdiagnosed in the general population. ... -
Does Physical Health Differ by Weight Status in Females Ages 55-79 with Coronary Heart Disease (CHD)?
(2019-03-05)Purpose: There is a higher prevalence of poor physical health and obesity in older adult populations and females, but there is limited research of this relationship. The purpose of this study is to assess the relationship ... -
Identifying Factors That May Affect Mortality of Infants with Hypoplastic Left Heart Syndrome
(2019-03-05)1. Purpose/BackgroundHypoplastic left heart syndrome (HLHS) is a severe congenital heart defect that is fatal without surgical intervention. The CDC states that HLHS make up approximately 3% of all congenital heart defects ... -
Impact of left atrial appendage (LAA) morphology on Outcomes of WATCHMAN device implantation (LMOW study)
(2019-03-05)Purpose: Left atrial appendage occlusion (LAAO) with a WATCHMAN device is approved to be used in atrial fibrillation (AF) patients who are not good candidates for long term oral anticoagulation therapy (OAT) as an alternative ... -
“Posterior STEMI- The solar eclipse of EKG”. How to uncode and not miss it
(2019-03-05)Background/Abstract: The clinical presentation of posterior myocardial infarction (PMI) is not always easy, not even for the cardiologist. True posterior myocardial infarction is difficult to recognise because the leads ... -
Preliminary Findings on Sex Differences in Response to Various Acute Stressors in Male and Female Mice
(2019-03-05)Purpose: Studies in both humans and animals have shown that pre-menopausal females are protected against the hypertensive and sympatho-excitatory effects of stress. Our goal was to identify whether sex difference exists ... -
Prevalence of Metabolic Syndrome Components and other Cardiovascular Risk factors related to Cardiovascular Disease and Cognition: A Comparison between the HABLE and UNAM cohorts.
(2019-03-05)Background: In the United States, the number two cause of death among Latinos in general, and Mexican Americans in particular is cardiovascular disease (CVD). Prevalence of major cardiovascular risk factors (CVRF) is higher ... -
Relationship between Sleep Duration and Hypertension in US Adults using Age- and BMI-Stratified Models
(2019-03-05)Relationship between Sleep Duration and Hypertension in US Adults using Age- and BMI-Stratified Models ABSTRACT Background: Hypertension is a strong risk factor for cardiovascular disease and mortality. Previous research ... -
Renal cortical antioxidant enzymes are not inactivated by cardiac arrest-resuscitation in pigs
(2019-03-05)Purpose: Cardiac arrest interrupts renal blood flow, and cardiopulmonary resuscitation (CPR) and restoration of sinus rhythm and renal perfusion may generate reactive oxygen species (ROS) that damage the kidneys. Cardiac ... -
Risk Factors Associated with Stroke in Pediatric Patients Undergoing Fontan Palliation
(2019-03-05)Risk Factors Associated with Stroke in Pediatric Patients Undergoing Fontan Palliation Puprose: Congenital heart disease is the leading known cause for stroke in childhood. The Fontan operation is performed as the third ... -
Safety and Efficacy Analysis of Balloon Cryoablation vs Radiofrequency Ablation in Atrial Fibrillation: A Retrospective Analysis. (SECARA AFib TRIAL)
(2019-03-05)Background: According to the ACC/AHA/HRS guidelines, Pulmonary-Vein Isolation has become the cornerstone approach in ablation for patients with medication refractory paroxysmal atrial fibrillation. (Class 1). Radiofrequency ... -
Sinus Node Dysfunction in a Young Female Without Identifiable Risk Factors
(2019-03-05)Background: Sinoatrial Node Dysfunction (SND) is a multifactorial disorder leading to symptomatic bradycardia and asystolic pauses. Epidemiological studies estimate the SND annual incidence at 0.8 per 1,000 person-years, ... -
