The aimwas to study the clinical course of CHF decompensation and the structural and functional state of the left ventricle in patients with ischemic CHF with systolic dysfunction and myocardial inflammation.Material and Methods.This study is open, non-randomized, prospective, registered on the ClinicalTrials.gov website, identification number: NCT02649517. The analysis included 25 patients (84% men, LVEF 29.17±9.4%) with ADHF of ischemic etiology. The average age of the patients was 60.12±9.3 years. All the patients underwent an echocardiography including 2D-speckle tracking technique to assess LV deformation. All patients underwent invasive coronary angiography to exclude the progression of coronary atherosclerosis, as a cause of CHC decompensation. An endomyocardial biopsy was performed to diagnose the presence of myocardial inflammation. We performed a comparative analysis of clinical, laboratory, instrumental indicators depending on the fact of diagnosis of inflammation in the myocardium.Results.There were no specific features of the clinical course of decompensation of ischemic CHF with systolic LV dysfunction depending on the inflammation in the myocardial tissue. However, in patients with inflammation, aortocoronary bypass surgery was more often performed (p=0.00650). In addition, in patients with inflammation, there was a decrease in apical rotation (p=0.0313), its systolic velocity (p=0.0157 with decompensation of CHF. A year later, improvement in LV biomechanics, but a continuing decrease in the absolute modulus of global longitudinal LV deformation (p=0.0431) after the anti-inflammatory treatment. Also a year later, in both groups there was an increase in the LV end-diastolic volume index (p=0.0180 and p=0.0280, respectively), a decrease in the interventricular septum of the LV (p=0.0491) in the group with inflammation, and an increase in the myocardial mass index of the LV (p=0.04995) in patients with inflammation.Conclusion.Decreased apical LV rotation and its systolic velocity in patients with ischemic CHF and LV systolic dysfunction, in view of the lack of clinical improvement after optimal myocardial revascularization, may be an additional criterion of concomitant inflammation in the myocardium. Among patients with ischemic CHF and LV systolic dysfunction, more pronounced cardiac remodeling, manifested by LV dilatation and thinning of LV wall, was observed in the group with inflammation.

Aim. To identify the features of the structural-functional state of the cardiovascular system in patients with pulmonary embolism (PE) in the presence of chronic heart failure (CHF) syndrome.Material and Methods. The study included 231 patients diagnosed with PE at admission to the hospital. Patients were further divided into subgroups depending on the verification of the diagnosis by computed tomography and the presence of CHF syndrome.Results and discussion. An increase in pressure in the pulmonary artery system contributed to the formation and aggravation of right ventricular systolic dysfunction, which acquired a greater prevalence and severity in the presence of CHF. This was confirmed by the echocardiographic signs of dysfunction of the right heart including increased linear dimensions of right cardiac chambers, right atrium volume index of 32.3 (29.4–37.9) mL/m2 versus 29.1 (26.6–32.3) mL/m2 (U = 1583.00, p < 0.001); greater prevalence of hemodynamic instability (proportion of patients with fainting or presyncope at hospital admission was 32% in the presence of CHF versus 16.7% without CHF; χ2 = 4,49, p < 0.05); and more significant increases in the laboratory markers of right ventricular dysfunction and injury included in the prediction model of adverse PE outcome [brain natriuretic peptide of 395 (204–789) pg/mL versus 104.2 (38.9–212) pg/mL (U = 1162.00, p < 0.001), high-sensitive troponin of 212 (194.5–297.6) ng/mL versus 184.8 (168.0–194.8) ng/mL (U = 279.50, p < 0.01), myocardial fatty acid-binding protein of 0.37 (0.18–1.2) ng/mL versus 0.2 (0.08–0.3) ng/mL (U = 530.00, p < 0.001), copeptin of 0.2 (0.05–0.92) ng/mL versus 0.09 (0.04–0.15) ng/mL (U = 563.00, p < 0.01), and reduced renal function].

How moxibustion improves chronic heart failure is extremely complex and still unclear. This study aimed to explore whether moxibustion inhibits autophagy and reduces inflammation by regulating mTOR expression to induce myocardial protective effects and alleviate symptoms associated with chronic heart failure. Echocardiography was used to detect cardiac function and cardiac structure of rats, including heart rate (HR), left atrium diameter (LA), left ventricular diameter (LV), left ventricular posterior wall (LVPW), interventricular septum (IVS), ejection fraction (EF), and fractional shortening (FS). BNP and NT-pro BNP levels were measured by enzyme-linked immunosorbent assay (ELISA). Autophagy-associated protein (ATG) genes and mTOR were detected by PCR. The expression of mTOR and phosphorylated-mTOR was detected through western blotting of proteins from myocardial tissue samples. The left ventricular inflammatory response was detected by immunohistochemistry and included ICAM-1, VCAM-1, MMP-2, and MMP-9 expression. The relationship between autophagy and inflammation was analyzed by correlation analysis. The results from echocardiography and ELISA showed that moxibustion could significantly improve heart function and structure. Western blot and PCR results showed that moxibustion treatment elevated mTOR expression. Further, moxibustion could inhibit autophagy and regulate the expression of key autophagy-related genes, including Vps34, ATG3, ATG5, ATG7, ATG12, and ATG13. By contrast, rapamycin could partially reduce the effects of moxibustion. Immunohistochemistry results indicated that moxibustion could reduce myocardial inflammation. Moreover, there was a positive correlation between autophagy and inflammation. Moxibustion can protect cardiac function in rats with heart failure, possibly inhibiting excessive autophagy of cardiomyocytes and reducing inflammatory reactions through the elevation of mTOR expression.

Background: Although natriuretic peptides are increasingly used for the management of chronic heart failure (CHF), there are sparse comparative data. Therefore, we compared the importance of influencing factors, the ability to detect left ventricular systolic dysfunction, and the prognostic power of midregional pro-atrial natriuretic peptide (MR-proANP), B-type natriuretic peptide (BNP), and aminoterminal pro-B-type natriuretic peptide (NT-proBNP) in patients with chronic heart failure. Methods and Results: MR-proANP, using a new assay directed at the midregion of aminoterminal-proANP, was compared with BNP and NT-proBNP, using conventional assays, in 797 patients with CHF. All three natriuretic peptides were independently influenced by left ventricular ejection fraction (LVEF), glomerular filtration rate (GFR), and the presence of ankle edema. Area under receiver-operator characteristic curves for detection of an LVEF <40% were similar between MR-proANP (0.799 [0.753– 0.844]) and BNP (0.803 [0.757– 0.849]), and NT-proBNP (0.730 [0.681– 0.778]. During a median observation time of 68 months, 492 patients died. In multiple Cox regression analysis each natriuretic peptide was the strongest prognostic parameter among various clinical variables, but proportion of explained variation showed that NT-proANP was a significantly stronger predictor of death than NT-proBNP and BNP (Figure ). Conclusions: Despite similarities in influencing factors and detection of reduced LVEF, MR-proANP outperformed BNP and NT-proBNP in the prediction of death. A new assay technology and the high biological stability of MR-proANP are potential explanations for these findings.
