This is defined as a left ventricular ejection fraction (LVEF) of 40% or less. About half of heart failure patients have a reduced ejection fraction. [2] Other types of heart failure are heart failure with mildly reduced ejection fraction (LVEF between 40% and 50%) and heart failure with preserved ejection fraction (LVEF 50% or higher). [1] [3]
Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
Heart failure (HF), also known as congestive heart failure (CHF), is a syndrome caused by an impairment in the heart's ability to fill with and pump blood.. Although symptoms vary based on which side of the heart is affected, HF typically presents with shortness of breath, excessive fatigue, and bilateral leg swelling. [3]
The CARE-HF trial showed that patients receiving CRT and optimal medical therapy benefited from a 36% reduction in all-cause mortality and a reduction in cardiovascular-related hospitalization. [35] However, around one third of patients with LVEF of 35% of less have a QRS complex duration of 120 ms or more.
The LVEF criteria used in these trials ranged from less than or equal to 30% in MADIT-II to less than or equal to 40% in MUSTT. [ 76 ] [ 75 ] Alternatively, a wearable cardioverter defibrillator (eg, LifeVest) can be used instead of an implantable defibrillator, and the wearable option can be used as a temporary bridge to an implantable device.
With Left Ventricular Ejection Fraction (LVEF) ≤ 35% due to prior Myocardial Infarction (MI) who are at least 40 days post-MI and are in NYHA Functional Class II or III; With Left Ventricular (LV) dysfunction due to prior MI who are at least 40 days post-MI, have an LVEF ≤ 30%, and are in NYHA Functional Class I
Surgery is recommended for chronic severe mitral regurgitation in symptomatic patients with left ventricular ejection fraction (LVEF) of greater than 30%, and asymptomatic patients with LVEF of 30-60% or left ventricular end diastolic volume (LVEDV) > 40%. [8]
Dapagliflozin is also considered as an option for people with heart failure with reduced ejection fraction with a LVEF <40%. [25] It can be given regardless of current diabetes status, in addition to standard medical therapy.
