In the second study, vitamin D supplementation failed to improve various measures of cardiac function and physical performance, although LVEF
was not measured.
In the performed pre-CABG echo and post-rehabilitation echo, LVEF
and diastolic function were determined.
In a comprehensive Cox regression multivariable analysis (age, sex, NYHA functional class, ischemic etiology, LVEF
, HF duration, diabetes, chronic obstructive lung disease, peripheral artery disease, hemoglobin, sodium, beta-blocker, and ACE inhibitor or angiotensin II receptor blocker treatments), eGFR categories according to the National Kidney Foundation calculated with the 4 equations remained significantly associated with mortality only for patients with eGFR between 30 and 59 or <30 mL x [min.
In contrast to other non-ischemic cardiomyopathies in which LVEF
has a strong prognostic impact, electrical and autonomic markers of cardiac abnormality carry a relevant amount of risk in Chagas disease.
was obtained by the modified biplane Simpson's method.
Duzenli et al demonstrated that the mean Sm correlated with LVEF
in HF patients but not in a normal population (10).
The researchers reported that in the 20 patients receiving CSCs, LVEF
increased from 29 percent to 36 percent at four months following infusion.
The following variables were measured: The LVEF
was calculated from apical four chamber view using the modified Simpson's method.
Data from Weikl and Noh (1992) were not included, as their method for assessment of LVEF
(MRI) was different from the one (scintigraphy) used in three other trials.
Cardiac resynchronization therapy (CRT) has become a standard method to treat advanced HF in patients with LVEF
< 35%, class III or IV HF and QRS duration > 120 msec.
All of the trials required sequential evaluation of cardiac function and changes in LVEF
, both symptomatic and asymptomatic, were reported.
After a mean follow-up of close to 2 years, the researchers saw significant absolute increases in LVEF
of 10% in the primary group and 11% improvement in the upgrade group.
