Supra-Normal Left Ventricular Function
The American Journal of Cardiology, 2023Heart failure (HF) is often categorized by left ventricular (LV) ejection fraction (LVEF). A new category of HF characterized by supra-normal LVEF (>65%), named HF with supra-normal ejection fraction (HFsnEF), has been recently proposed. Some studies reported that patients with supra-normal LVEF might have an increased risk of long-term major adverse ...

Improved Left Ventricular Function After Chronic Left Ventricular Unloading
The Annals of Thoracic Surgery, 1996This study assessed the effect of prolonged left ventricular unloading on native ventricular function.We reviewed data from 31 patients (30 men, 1 woman) supported more than 30 days (mean, 137 days; range, 31 to 505 days) with the HeartMate left ventricular assist system.

Giornale italiano di cardiologia, 1994
TEE is widely used for intraoperative monitoring of global and regional left ventricular function during cardiac surgery. However, caution is necessary in assessing changes in left ventricular function before and after cardiopulmonary bypass because of the unequal loading conditions and the interference of catecholamine administration.

Left ventricular diastolic function
Critical Care Medicine, 2007Cardiovascular morbidity and mortality resulting from congestive heart failure are major concerns for the critical care physician. Although heart failure is commonly associated with impaired systolic function, in up to one half of cases, heart failure occurs exclusively on the basis of an impairment of diastolic function.

Left ventricular function during sepsis
Critical Care Medicine, 1989The prevalence and prognostic significance of left ventricular involvement in septic patients without shock was investigated. Systolic time intervals (STI) and preejection period/left ventricular ejection time ratio (PEP/LVET) were used to assess left ventricular function. Forty-nine patients, 22 of whom ultimately died, were studied.

Left ventricular function in malnutrition
American Journal of Physiology-Heart and Circulatory Physiology, 1987Twenty-one dogs were chronically instrumented with ultrasonic left ventricular dimension transducers and micromanometers to elucidate the effects of acute protein-calorie malnutrition on cardiac function. Ten dogs received a regular diet for 3 wk, whereas 11 dogs received a protein-calorie-deficient diet designed to achieve a mean weight loss of 20-25%

Left Ventricular Aneurysmectomy in Patients with Poor Left Ventricular Function
Scandinavian Journal of Thoracic and Cardiovascular Surgery, 1992Physical performance and left ventricular (LV) function in the resting state were assessed in 22 patients with postinfarction anterior-apical left ventricular aneurysm (LVA) and global ejection fraction less than or equal to 20% who subsequently underwent radical LVA resection.

MRI of left ventricular function
Journal of Nuclear Cardiology, 2007Cardiac magnetic resonance imaging (CMR) is widely recognized as the most accurate noninvasive imaging modality for the assessment of left ventricular (LV) function. By use of state-of-the-art magnetic resonance imaging (MRI) scanners, electrocardiography (ECG)-gated cine images depicting LV function with high contrast and excellent spatial and ...

Global left ventricular (LV) function is an important prognostic parameter and is useful for therapeutic decision-making. Since its introduction, twodimensional (2D) echocardiography has played an important role in the quantitation of LV function. However, the limitations of 2D echocardiography for the accurate determination of cardiac volumes and ...

Left Stellate Ganglion Block Impairs Left Ventricular Function
Anesthesia & Analgesia, 1994Stellate ganglion block (SGB) is an established procedure for the diagnosis and treatment of chronic pain. SGB results in an acute sympathetic denervation of a part of the left ventricular (LV) wall innervated by the blocked ganglion, which may impair regional contractility.
