Assessment of sacubitril/valsartan effects on left ventricular dynamics using 3D echocardiography and 3D strain in heart failure with reduced ejection fraction patients.

BACKGROUND: Three-dimensional (3D) echocardiography and 3D strain parameters have been used for a comprehensive quantitative assessment of left ventricular (LV) myocardial dynamics. So far, there are no data on sacubitril/valsartan effects on cardiac functions and LV reverse remodeling using 3D echocardiography. This study aimed to evaluate the effects of sacubitril/valsartan on the LV functions using two-dimensional (2D) echocardiography, 3D echocardiography, and the 3D strain parameters. METHODS: A single-center prospective cohort study which included 100 heart failure with reduced ejection fraction (HFrEF) patients with guidelines-approved indications for sacubitril/valsartan treatment. Patients received a short course (3-month) of sacubitril/valsartan. 3-month follow-up 2D, 3D echocardiographic parameters, and 3D strain were compared to baseline parameters. RESULTS: The results of the study revealed a significant improvement in left ventricular dynamic functions at 3-month follow-up with an improvement in left ventricular systolic function (mean left ventricular ejection fraction (LVEF) increased from 27.65±4.98% to 32.89±6.03%, P<0.001). Comparison of HFrEF patients with ischemic and non-ischemic etiologies showed that echocardiographic parameters significantly improved in both groups after 3 months of sacubitril/valsartan treatment. There was no statistically significant difference between both groups regarding echocardiographic parameters at baseline and 3-month follow-up. CONCLUSIONS: In a single-center prospective observational cohort study evaluating the effects of short-term (3-month course) sacubitril/valsartan treatment on LV dynamics assessed by 3D echocardiography and 3D strain, sacubitril/valsartan was associated with a significant improvement of LV systolic functions and reverse remodeling effects in both ischemic and non-ischemic HFrEF patients.

THE EFFECTS OF ETANERCEPT AND CABERGOLINE ON ENDOMETRIOTIC IMPLANTS, UTERUS AND OVARIES IN RAT ENDOMETRIOSIS MODEL.

The pathophysiology of endometriosis is still unknown and treatment options remain controversial. Searches focus on angiogenesis, stem cells, immunologic and inflammatory factors. This study investigated the effects of etanercept and cabergoline on ovaries, ectopic, and eutopic endometrium in an endometriosis rat model. This randomized, placebo-controlled, blinded study included 50 rats, Co(control), Sh(Sham), Cb(cabergoline), E(etanercept), and E + Cb(etanercept + cabergoline) groups. After surgical induction of endometriosis, 2nd operation was performed for endometriotic volume and AMH level. After 15 days of treatment: AMH level, flow cytometry, implant volume, histologic scores, immunohistochemical staining of ectopic, eutopic endometrium, and ovary were evaluated at 3rd operation. All groups had significantly reduced volume, TNF-α, VEGF, and CD 146/PDGF-Rß staining of endometriotic implants comparing to the Sh group (p < 0.05).TNF-α staining of eutopic endometrium in all treatment groups was similar to Sh and Co groups (p > 0.05). E and E + Cb groups significantly decreased TNF-α staining in the ovary comparing to Sh, Co, and Cb groups (p < 0.05). All treatment groups had significantly higher AFC compared to the Sh group. CD25+ Cells' median percentage was significantly increased in the E + Cb group compared to Co, Sh, Cb, and E group. E + Cb group had a significantly higher CD5+ Cells' level than the Co group (p = 0.035). In conclusion; Etanercept and/or Cabergoline decreased volume, TNF-α, VEGF, and CD 146/PDGF-Rß staining of the ectopic endometrial implant. E and E + Cb treatment decreased TNF-α levels in the ovary. E + Cb also increased peripheral blood CD25+ & CD5+ Cell's.
