What the function of left ventricle in systemic circuit ?
Best insight from top research papers
The left ventricle (LV) functions as a pump to deliver oxygenated blood through the systemic circuit to meet the metabolic needs of the body's tissues . It receives blood from the left atrium and contracts to eject the blood into the large arteries of the systemic arterial tree . The LV is ideally matched to its afterload, which optimizes ventricular/vascular coupling and cardiac efficiency while minimizing myocardial oxygen consumption . The LV's function can be understood by considering its pressure-volume properties, which are influenced by muscle tension-length properties and a time-varying elastance . The LV's systolic properties are characterized by an end-systolic pressure-volume relationship (ESPVR) and contractility, while diastolic properties are influenced by compliance . The LV's function is also influenced by factors such as heart rate and left ventricle shape, which can affect hemodynamic efficiency . Overall, the LV plays a crucial role in maintaining systemic circulation and adapting to changes in activity levels and organ function .

What role does autonominc nervous system have in cardiac function?5 answersThe autonomic nervous system (ANS) plays a crucial role in cardiac function by finely tuning heart rate and contractility. It consists of sympathetic and parasympathetic components, with their combined output reflected in the sympathovagal balance. In conditions like heart failure, there is a shift towards sympathetic predominance and decreased vagal activity, leading to adverse effects on cardiac function. Autonomic activation influences not only heart rate and hemodynamics but also cellular properties of individual myocytes, contributing to cardiac arrhythmogenesis. Neuromodulatory therapies, such as chronic vagus nerve stimulation, show promise in improving heart failure symptoms and status by exerting cardioprotective actions. Overall, the ANS regulates cardiac rhythm through its sympathetic and parasympathetic branches, impacting cardiac, vascular, and visceral functions.
What is the role of the left ventricle?4 answersThe left ventricle is responsible for pumping oxygenated blood throughout the body. It contracts to force blood through the aortic valve and into the systemic arterial tree, supplying oxygen and nutrients to the tissues. The left ventricle's function is crucial for maintaining the metabolic requirements of the body's organs and tissues. It plays a role in maintaining mean arterial blood pressure by altering peripheral resistance through the arterioles. The left ventricle's efficiency and cardiac output are optimized when it is ideally matched to its afterload, resulting in minimal myocardial oxygen consumption. The left ventricle's function can be affected by injury or maladaptive changes, leading to decreased function and symptoms of disease. Left ventricular dysfunction can be evaluated using parameters such as ejection fraction and left ventricle global longitudinal strain (LV GLS).
What is the role of the left ventricular assist system in the treatment of heart failure?5 answersThe left ventricular assist system plays a significant role in the treatment of heart failure. It is used as a last resort for patients who are not eligible for heart transplantation. The system provides mechanical assistance to the failing left ventricle, improving hemodynamic stability and allowing for recovery of secondary organ failure. It can be used as a bridge to transplantation, providing support until a suitable cardiac allograft becomes available. Additionally, left ventricular assist device implantation has shown satisfactory early results in improving cardiac function and increasing the 6-minute walking test distance. However, right heart failure (RHF) can be a complication associated with left ventricular assist device therapy, and its mechanisms and treatments are still being studied. Despite its limitations, the left ventricular assist system offers a valuable treatment option for patients with advanced heart failure, improving survival rates and quality of life.
What is the role of the parasympathetic nervous system in the cardiovascular system?5 answersThe parasympathetic nervous system (PSNS) plays a crucial role in maintaining cardiovascular homeostasis by modulating and down-regulating the responses of the organism to internal and external stimuli. It is responsible for the restorative effects on heart rate, blood pressure, and contractility. Activation of the PSNS promotes safety for patients in the peri-operative period during anesthesia delivery. Chronic psychosocial factors have been shown to be directly linked to the development of hypertension, cardiovascular disease, and stroke, and therapies that attenuate autonomic imbalance via modulation of increased sympathetic outflow have been shown to alleviate clinical symptoms. Dysfunction in the autonomic nervous system (ANS) regulatory role promotes cardiovascular morbidity and mortality, and ANS imbalance may evoke electrophysiological cardiac defects, vascular pathologies, pathogenic myocardial cell signaling, oxidative stress, inflammation, and neural defects throughout the cardiovascular tissue. The role of the PSNS in the cardiovascular system is also relevant in the development and progression of hypertension-related target organ damage, congestive heart failure, cardiac arrhythmias, obesity, metabolic syndrome, obstructive sleep apnea, and chronic renal disease.
What is ventricular taquichardia?3 answersVentricular taquichardia is a cardiac arrhythmia characterized by rapid and irregular heartbeats originating from the ventricles. It can be triggered by stress, physical activity, or emotional factors. Ventricular taquichardia can be associated with conditions such as ventricular noncompaction and catecholaminergic polymorphic ventricular tachycardia (CPVT). CPVT is an inherited heart rhythm disorder that can lead to bi-directional ventricular tachycardia in the presence of catecholamines. It is often diagnosed in children and young adults with a structurally healthy heart. The diagnosis of ventricular taquichardia can be confirmed through stress tests or the infusion of sympathicomimetic drugs, along with genetic analysis to identify mutations in specific genes such as RYR2 and CASQ2. Treatment options for ventricular taquichardia include implantable cardioverter-defibrillator devices and sympathetic cardiac denervation.
How cardiac muscles work?5 answersCardiac muscles work by contracting and relaxing to pump blood throughout the body. The anatomical structure, cellular composition, and conduction pathways of the heart all contribute to its efficient functioning. The cardiac myocyte, which is the muscle cell of the heart, generates and spreads the electrical signals that initiate contractions. Excitation-contraction coupling is the process by which the electrical signals trigger the release of calcium ions, leading to muscle contraction. The heart muscle also relies on metabolism and energetics to sustain its continuous contractions. Additionally, the heart adapts to changes in blood volume and is regulated by the autonomic nervous system, which controls heart rate and the strength of contractions. Overall, the heart muscles play a crucial role in maintaining adequate tissue and organ perfusion throughout the body.
