Patients were grouped into those with normal post-stress left ventricular function (Group I) and those with impaired function (EF Results Between the Group I and II, cardiac events as well as chest pain symptoms, smoking, diabetic complications were significantly different (P P = 0.016). In ...
A. About half of patients with new diagnoses of heart failure have normal or near normal global ejection fractions (EF). These patients are diagnosed with diastolic heart failure or heart failure with preserved/normal EF(HFnlEF). Page %P Close Plain text Look Inside Citations Within this...
EF and FS did not change significantly by time. Early (E) flow velocity and early myocardial (Em) velocity were higher than late (A) flow velocity and atrial systolic (Am) velocity for LV, while A and Am velocities were higher than E and Em velocities for RV, respectively during the ...
The role of right and left ventricular function in the ventilatory response to exercise in chronic heart failure. Right ventricular function may be an important determinant of exercise capacity, peak oxygen consumption (VO2), and the ventilatory response to carbon diox... AL Clark,JW Swan,R Lane...
The LV volume and ejection fraction (EF) were measured with the modified biplane Simpson's method from the apical 4- and 2-chamber views (20). LV mass was calculated according to Devereux formula (21). Left atrial volume was calculated with the biplane area-length method from the apical 4...
diastolic and end-systolic volumes (EDVandESV, respectively) and yielded standard cardiac function metrics, such as stroke volume\(SV=EDV-ESV\), ejection fraction\(EF = SV/EDV\), and cardiac output\(CO=SV*HR\). We defined stroke work as the area inside the PV loop and identified ...

Effect of somatic growth, strain, and sex on double-chamber plethysmographic respiratory function values in healthy mice Double-chamber plethysmography has been recognized since 1979 as a reference technique to measure pulmonary function values in guinea pigs, but it has not ... TD Flandre,PL ...
The majority (50% to 70%) of patients with severe aortic stenosis (AS) develop left ventricular (LV) hypertrophy with normal LV cavity size and ejection fraction (EF), which allows maintenance of normal LV pump function. These patients with severe AS and normal transvalvular flow rate exhibit...
To diagnose heart failure with preserved ejection fraction (HFpEF), the following three criteria have to be fulfilled [1–8]: 1. Signs and symptoms generally present in heart failure, and 2. Preserved left ventricular ejection fraction, defined as LV-EF ≥ 50%, in the presence of a nor...
