What does hyperdynamic left ventricular systolic function mean?
A hyperdynamic left ventricle (ejection fraction ≥ 70%) seen on stress radionuclide myocardial perfusion imaging bears strong association with diastolic dysfunction and is therefore a marker of heart failure with preserved ejection fraction in appropriate clinical setting.
What does it mean when your heart is Hyperdynamic?
Medical Definition of hyperdynamic : marked by abnormally increased muscular activity especially when of organic origin myocardial infarction, with the remaining left ventricular walls being normal to hyperdynamic— R. A. Nishimura et al.
What is LV Hyperdynamic?
The LV is hyperdynamic to compensate for decreased preload from the RV. Based on clinical findings, including chest pain, shortness of breath, hypoxia, tachycardia, elevated BNP, troponin, and signs of right-sided heart failure on POCUS, a CT scan of the chest was ordered to assess for pulmonary embolism (PE).
What is hyperdynamic left ventricular ejection fraction?
Hyperdynamic left ventricular ejection fraction (HDLVEF) on transthoracic echocardiography (TTE) is a frequent finding in the intensive care unit (ICU). The American College of Cardiology (ACC) defines HDLVEF as a left ventricular ejection fraction >70 % [1].
What is concentric LVH?
LVH is commonly measured by electrocardiography, echocardiography, and magnetic resonance imaging Concentric LVH is an increased left ventricular mass index with a relative wall thickness ≥0.45 (1). Eccentric LVH is an increased left ventricular mass index with a relative wall thickness <0.45 (1).
What causes Hyperdynamic ejection fraction?
Too high EF (more than 70%), which is called a hyperdynamic LVEF, is commonly found in patients with trauma in the intensive care unit [33]. Reduced EF in heart failure is caused by muscle damage that remodels the cells and reduces contractility.
What causes Hyperdynamic?
The hyperdynamic circulation begins in the portal venous bed as a consequence of portal hypertension due to the increased resistance to flow from altered hepatic vascular morphology of chronic liver disease.
How is Hyperdynamic treatment?
The cornerstone of medical therapy for cerebral vasospasm is so-called hyperdynamic therapy. Also referred to as triple-H therapy, this strategy includes the use of hypertension, hypervolemia, and hemodilution to optimize cerebral perfusion.
What is concentric left ventricular hypertrophy?
Concentric left ventricular hypertrophy is an abnormal increase in left ventricular myocardial mass caused by chronically increased workload on the heart, most commonly resulting from pressure overload-induced by arteriolar vasoconstriction as occurs in, chronic hypertension or aortic stenosis.
How serious is concentric LVH?
Once LVH is developed, it puts the patient at significant risk of developing myocardial ischemia and infarction, heart failure, dysrhythmias, or even sudden death. The risk of cardiovascular disease and adverse major cardiac events increases with increasing LVM and decreases with the regression of LVH.
Is concentric LVH normal?
The results are as follows: LV size and systolic functions are normal with EF of 67%. There is mild concentric LV hypertrophy. The diastolic filling pattern is normal of the age of the patient.
What is hyperdynamic LV function?
A hyperdynamic LV influences the assessment of RV function in preterm infants. The presence of a patent ductus arteriosus at 1 week of age is associated with lower values of RV strain and fractional area of change.
What is hyperdynamic LV?
hyperdynamic LV makes the diagnosis of systolic heart failure as the cause of shortness of breath less likely. The more common presentation of systolic heart failure is a hypodynamic LV and RV (Video Set 3, Video 2). In addition, the finding of a hyperdynamic LV with an associated hyperdynamic RV makes the diagnosis
What is hyperdynamic EF?
Hyperdynamic left ventricular ejection fraction (HDLVEF) on transthoracic echocardiography (TTE) is a frequent finding in the intensive care unit (ICU). The American College of Cardiology (ACC) defines HDLVEF as a left ventricular ejection fraction >70 % [1].
