Filter by:Heart failure is a special clinical syndrome such as difficulty breathing, fatigue, and swollen legs characterized by increased JVP, crackle lung sounds, and peripheral edema caused by heart disorders both structural and/or functional, resulting in decreased cardiac output and increased intracardiac pressure at rest and activity. Body positioning has been shown to affect stroke volume and parasympathetic modulating activity. The right lateral 30" semifowler position is a very safe position in heart failure patients admitted to the ICU. Although body positioning can affect stroke volume, and parasympathetic modulation, it is not yet clear what effect it has on cardiac output
Arrhythmias early in the recovery period after cardio thoracic surgery are common they develop in 11 to 40 percent of patients after coronary-artery bypass grafting. The right chose of sedative agent could decrease the level of arrhythmia incidence.
Patients scheduled for cardiac surgery are fragile. Hemodynamic fluctuation might be associated with adverse outcomes. Therefore, it is essential to keep hemodynamics stable during and after the induction period. Previous studies have shown that topical anesthesia can provide excellent superior supraglottic and subglottic local anesthetic effects and can significantly reduce the dosage of intravenous anesthetics. Therefore, we designed this study to explore whether the combination of topical anesthesia and intravenous anesthetics could decrease the stress response of endotracheal intubation and keep hemodynamics stable during and after the induction period.
Depersonalized multi-centered registry initiated to analyze dynamics of non-infectious diseases after SARS-CoV-2 infection in population of Eurasian adult patients.
MindMics earbuds is a new technology designed enhance an individual's quality of life by continuously monitoring the heart rate, stress, and blood pressure allowing patients to make decisions regarding their health. MindMics has a working prototype of the ear buds which will perform all the conventional tasks of earbuds (listen to music, etc.), but, in addition, will measure heart rate, stress, blood pressure. The earbuds capture the sounds made by the various cardiac structures pulsing and moving blood. The sound is caused by the acceleration and deceleration of blood and the turbulence developed during rapid blood flow.
In this patient engagement study, patients and partners will attend a presentation, group meeting and responding to the survey to help the research team gage the acceptability of using a biological therapy to prevent cardiac arrhythmia. Patient Partners will also help to clarify which outcomes are important to patients, to ensure the selected outcomes align with patient interests.
The aim of this study is to evaluate if internet- delivered cognitive behavior therapy (CBT), based on exposure principles and behavioral activation, improves QoL and symptom burden in patients with symptomatic atrial fibrillation (AF), controlling for expectancy of improvement and attention from a caregiver, using an active control group (stress management). The study will include 260 patients with symptomatic AF despite optimal medical treatment in accordance with current guidelines.
During Laparoscopic cholecystectomy, carbon dioxide (CO2) pneumoperitoneal laparoscopic surgery, CO2-pneumoperitoneum activates the sympathoadrenomedullary system to increase the release of catecholamines such as epinephrine (E) norepinephrine (NE) and dopamine (DA). During stress, E and NE are secreted by the adrenal medulla into blood circulation to promote glycogenolysis to increase blood glucose, speed up lipolysis and accelerate heartbeats. Stellate g anglion block (SGB) reters to the blockade of sympathetic nerves including the large area covered by middle cervical, vertebral arterial. stellate ganglions and ther pre- and post- ganglions. SGB affects both peripheral and central nervous systems. In the peripheral system. the sympathetic pre- and post-ganglionic fibers in the innervated areas of stellate ganglion are affected. Therefore, the control of vascular dilatation and constriction, muscular movement, bronchial smooth muscle relaxation and contraction, and pain conduction, by sympathetic nerves is inhibited. In the central nervous system, the hypothalamus is mainly involved in the regulation of systemic autonomic nervous, immune and endocrine systems, and to maintain homeostasis. CO2-pneumoperitoneum causes severe stress-related homeostatic disorders including arrhythmia and blood pressure changes. This study will examine the effects of stellate ganglion block (SGB) on hemodynamics and stress response in patients undergoing CO-pneumoperitoneal surgery.
Catheter ablation in patients with ventricular tachycardia using a new mapping algorithm called, parallel mapping, that is aimed to increase the specificity of mapping and the outcome of ablation.
The purpose of the study is to see if monthly telemedicine computer visits (visits using the computer) improve the time it takes to identify and treat an arrhythmia. The second purpose is to see if monthly telemedicine computer visits improves the participant's understanding of the arrhythmia and improves how the participant feels with daily activities.
