Introduction: Atrial arrhythmia (AA) and left ventricular systolic dysfunction (LVSD) frequently co-exist, which loom as burgeoning public health problems. It is difficult to determine whether a tachycardia is the indicator or consequence of LVSD in patients with tachycardia and LVSD. Tachycardia mediated cardiomyopathy (TCM) raises a “chicken or egg” question. Regardless of the etiology, the patients with severe LVSD are considered as the candidate for the implantation of cardioverter defibrillator as primary prevention. It is well known that the LVSD improves after the successful treatment of AA in TCM population. However, enlarged left ventricular end-diastolic dimension (LVDd) is considered as a parameter of irreversible LVSD. Hypothesis: Enlarged LVDd could not be a predictor for irreversible LVSD in patients with AA. Methods: We assessed patients with persistent AA and heart failure (Ejection Fraction (EF) <45%) who were received aggressive rhythm control therapy and maintained sinus rhythm with catheter ablation, electrical cardioversion and anti arhythmic drugs. Echocardiographic parameters and brain natriuretic peptide (BNP) were evaluated before and after the treatment. Results: Twenty-five patients with persistent AA and LVSD (23 men; mean age 63.8±9.3 years) were enrolled in this study. After restored and maintained SR, EF and left ventricular end-systolic volume (ESV) and BNP were improved in all patients respectively (EF 30.7±10.7 to 54.0±7.3%, ESV; 82.1±32.4 to 50.6±24.1ml, BNP; 379.2±237.9 to 48.0±29.7pg/ml P<0.001). In the other hand, there were no significant improvement of LVDd and left ventricular end-diastolic volume (EDV) (LVDd; 54.7±7.6 to 54.3±5.5mm P=0.68, EDV; 120.1±37.9 to 108.2±38.0ml P=0.16). Enlarged LVDd >60mm were observed in 5 patients (25%) before the treatment. EF was normalized in patients with severe LVSD (EF<35%, n=13; 52%). Conclusions: The unnecessary device implantation could be avoided in patients with AA and severe LVSD with aggressive rhythm control therapy. Even in the patients with severe LVSD and enlarged LVDd, LVSD is reversible when AA exists.

Abstract Chronic obstructive pulmonary disease (COPD) greatly affects the quality of life, significantly limiting the physical capabilities of people suffering from it. The prevalence of COPD worldwide is about 7,6 %, and it is one of the main causes of morbidity and mortality in today’s society. An urgent medical and social problem of our time is the development of pulmonary hypertension (PH) in patients with COPD. Transthoracic echocardiography is important for PH screening. It has the highest sensitivity and specificity among non-invasive examinations, and unlike catheterization of the right heart, it does not require special equipment and centers for dynamic monitoring of patients with PH. When pulmonary hypertension, there is a pronounced remodeling of the heart. At the first stage, it occurs in the right parts of the heart, and in the future, as a consequence, it is accompanied by a violation of systolic inter-ventricular interactions. Purpose of the study. To determine the characteristics of left ventricular systolic function in patients with pulmonary hypertension on the background of COPD. Materials and methods. Results of the study are based on data from a comprehensive survey of 170 COPD patients aged 40 to 65 years, 123 of which had pulmonary hypertension and 47 ones had no pulmonary hypertension. Results and discussion. In the group of patients with PH on the background of COPD, the shock volume was 74,72 cm3 (64,60–83,09) and it was significantly lower compared to the level of 82,04 cm3 (75,20–87,76) of the COPD group without PH (p < 0,05). Such echocardiographic index as left ventricular ejection fraction in groups of patients with COPD with PH and without it, was 57,59% (53,84–62,19) and 59,44% (56,67–61,88), respectively, and it was significantly lower compared to the level of 64,62% (62,86–67,91) of healthy individuals (p < 0,05). There was a straight increase in end-diastolic volume and end-systolic volume in the subgroup of patients with COPD duration > 12 years compared to the subgroup ≤ 12 years, 134,17 cm3 (117,00–150,15) versus 125,52 cm3 (105,20–139,60) and 57,37 cm3 (51,70–65,60) versus 51,40 cm3 (43,08–59,84), respectively (p < 0,05). The impact volume had no significant differences between subgroups depending on the duration of COPD (p > 0,05). The level of LV ejection fraction was significantly lower in the subgroup of COPD duration > 12 years 56,64% (52,65–59,73) against the subgroup ≤ 12 years (p < 0,05). There were no significant differences between the levels of systolic heart function indicators: end-diastolic volume, end-systolic volume, shock volume, and LV EF depending on the stage of COPD (p > 0,05). Correlation analysis revealed significant relationships between the following indicators: duration of COPD and ESV (R = +0,24, p = 0,008); duration of COPD and LV EF (R = –0,25, p = 0,006); MPAP and EDV (R = –0,22, p = 0.02);MPAP and SV (R = –0,26, p = 0,004); MPAP and LV EF (R = –0,21, p = 0,02). Keywords: left ventricular systolic function, pulmonary hypertension, chronic obstructive pulmonary disease, mean pulmonary artery pressure.

Objective. To investigate the correlation between TREM-1 and LPS-induced left ventricular systolic dysfunction in BALB/c mice.Methods. Male BALB/c mice were randomly divided into 3 groups: LPS, LPS/TREM-1, and control groups which were injected intraperitoneally with 25 mg/kg LPS, 5 μg TREM-1mAb 1 h after LPS challenge, and sterilized normal saline, respectively. Left ventricular systolic function was monitored by echocardiography at 6 h, 12 h, and 24 h. Meanwhile, TNF-α, IL-1β, and sTREM-1 in serum and myocardium were determined by ELISA or real-time PCR; at last left ventricles were taken for light microscopy examination.Results. FS and EF in LPS/mAbTREM-1 group, significantly declined compared with LPS and control group at 12 h, were accompanied with a markedly increase in serum IL-1β(at 6 h) and sTREM-1 (at 12 h and 24 h) expression. Myocardium TNF-α(at 6 h and 24 h) and sTREM-1 (at 6 h) were significantly higher in LPS/mAbTrem-1-treated mice than in time-matched LPS-treated mice; meanwhile myocardium TNF-αmRNA were markedly increased in comparison with LPS-treated or saline-treated mice at 24 h. Besides, mAbTREM-1 aggravated LPS-induced myocardial damage was observed.Conclusions. Our results suggest that TREM-1 is significantly associated with LPS-induced left ventricular systolic dysfunction in BALB/c mice.

Abstract Background This study aims to evaluate the early and mid-term outcomes of mitral valve repair for degenerative mitral regurgitation (MR) in patients with left ventricular systolic dysfunction. Methods From January 2005 to December 2016, the profiles of patients with degenerative MR who underwent mitral valve repair at our institution were analyzed. Left ventricular systolic dysfunction was defined as an ejection fraction < 60% or left ventricular end-systolic dimension > 40 mm. Finally, 322 patients with left ventricular systolic dysfunction were included in this study. The prognosis of left ventricular function during follow-up was evaluated and preoperative factors associated with deteriorated left ventricular systolic function during follow-up were analyzed. Results The in-hospital mortality rate was 1.6%. The rate of eight-year overall survival, freedom from reoperation for mitral valve and freedom from recurrent MR were 96.9, 91.2 and 73.4%, respectively. Intraoperative residual mild MR (hazard ratio 4.82) and an isolated anterior leaflet lesion (hazard ratio 2.48) were independent predictive factors for recurrent MR. During follow-up, 212 patients underwent echocardiography examinations at our institution. Among them, 132 patients had improved left ventricular systolic function, and 80 patients had deteriorated left ventricular systolic. Freedom from recurrent MR was found in 75.9% of the improved left ventricular systolic function group and 56.2% of the deteriorated left ventricular systolic function group (P = 0.047). An age > 50 years (odds ratio 2.40), ejection fraction≤52% (odds ratio 2.79) and left ventricular end-systolic dimension≥45 mm (odds ratio 2.31) were independent risk factors for deteriorated left ventricular systolic function during follow-up. Conclusions Mitral valve repair could be safely performed for degenerative MR in patients with left ventricular systolic dysfunction. Intraoperative residual mild MR and an isolated anterior leaflet lesion were independent predictive factors for recurrent MR. An age > 50 years, ejection fraction≤52% and left ventricular end-systolic dimension≥45 mm were independent risk factors for deteriorated left ventricular systolic function during follow-up.

Abstract Background: Several studies have reported left ventricular systolic dysfunction as measured by the global longitudinal strain (GLS) in patients with mitral stenosis. This study aims to determine left ventricular systolic function changes using global longitudinal strain early after balloon mitral valvuloplasty (BMV) and on long-term observation.Methods: Baseline echocardiography data and GLS were taken before BMV, followed up early after (2 to 7 days), and in the long-term (6 months to 1 year) after BMV.Result: Among 36 patients, the mean age was 43.41±10.04 y.o, female dominant (72%); the majority have atrial fibrillation (56%), with a median mitral valve area (MVA) before BMV of 0.6 (0.2-1.3) cm2 and mean mitral valve gradient before BMV of 12.95 ± 5.29 mmHg. GLS increased from -14.34 ± 3.05% to 15.84 ±3.11% and increased further to -17.29 ± 2.80% (p<0.05), at pre-BMV- early post-BMV, and long-term follow up, respectively. Conclusions: There is a significant improvement in LV GLS early after BMV compare to baseline. The GLS improved further at long-term evaluation (six months until one year) after BMV.

The Relationship

Aim. To study the relationship of mechanisms of microcirculation regulation and intracardiac hemodynamics in patients with heart failure (HF).Material and methods. In eighty patients with NYHA class II-IV HF, microcirculation was assessed by laser Doppler flowmetry and intracardiac hemodynamics — by echocardiography.Results. The patients were divided into 3 groups depending on HF type: with preserved ejection fraction (CHpEF) (>50%) — 27 patients, mid-range EF (CHmrEF) (40-50%) — 25 patients, reduced EF (CHrEF) (<40%)  — 28 patients. Comparative analysis revealed a significant decrease in the coefficient of variation (CV) in all groups without microcirculation differences. The greatest number of significant correlations was found between the myogenic component of microcirculation frequency range and the following echocardiographic parameters: left ventricular EF (r=0,351, p<0,05); end-diastolic dimension (r=-0,492, p<0,05), end-systolic dimension (r=-0,474, p<0,05), end-diastolic volume (r=-0,544, p<0,05), end-systolic volume (r=-0,449, p<0,05), etc.Conclusion. In patients, regardless of left ventricular EF, satisfactory perfusion was obtained, which is achieved due to inhibition of active mechanisms and compensatory activation of passive mechanisms of microcirculation regulation. The relationship between the development of myocardial remodeling and microcirculatory dysfunction is noted.

Heart failure is a common debilitating illness, associated with significant morbidity and mortality, rehospitalisation and societal costs. Current guidelines and position statements emphasise the management of patients with overt symptomatic disease, but the increasing prevalence of congestive heart failure underscores the need to identify and manage patients with early left ventricular dysfunction prior to symptom onset. Asymptomatic left ventricular systolic dysfunction (ALVSD), classified as stage B heart failure, is defined as depressed left ventricular systolic function in the absence of clinical heart failure. Early initiation of therapies in patients with presumed ALVSD has been shown to lead to better outcomes. In this article, the authors clarify issues surrounding the definition and natural history of ALVSD, outline clinical tools that may be of value in identifying patients with ALVSD and highlight potential opportunities for future investigations to better address aspects of our understanding of this complex syndrome.

Abstract Background Central apneas (CA) and obstructive apneas (OA) are highly prevalent in heart failure (HF) both with reduced and preserved systolic function. However, a comprehensive evaluation of apnea prevalence across HF according to ejection fraction (i.e HF with patients with reduced, mid-range and preserved ejection fraction- HFrEf, HFmrEF and HFpEF, respectively) throughout the 24 hours has never been done before. Materials and methods 700 HF patients were prospectively enrolled and then divided according to left ventricular EF (408 HFrEF, 117 HFmrEF, 175 HFpEF). All patients underwent a thorough evaluation including: 2D echocardiography; 24-h Holter-ECG monitoring; cardiopulmonary exercise testing; neuro-hormonal assessment and 24-h cardiorespiratory monitoring. Results In the whole population, prevalence of normal breathing (NB), CA and OA at daytime was 40%, 51%, and 9%, respectively, while at nighttime 15%, 55%, and 30%, respectively. When stratified according to left ventricular EF, CA prevalence decreased from HFrEF to HFmrEF and HFpEF: (daytime CA: 57% vs. 43% vs. 42%, respectively, p=0.001; nighttime CA: 66% vs. 48% vs. 34%, respectively, p&lt;0.0001), while OA prevalence increased (daytime OA: 5% vs. 8% vs. 18%, respectively, p&lt;0.0001; nighttime OA: 20 vs. 29 vs. 53%, respectively, p&lt;0.0001). When assessing moderte-severe apneas, defined with an apnea/hypopnea index &gt;15 events/hour, prevalence of CA was again higher in HFrEF than HFmrEF and HFpEF both at daytime (daytime moderate-severe CA: 28% vs. 19% and 23%, respectively, p&lt;0.05) and at nighttime (nighttime moderate-severe CA: 50% vs. 39% and 28%, respectively, p&lt;0.05). Conversely, moderate-severe OA decreased from HFrEF to HFmrEF to HFpEF both at daytime (daytime moderate-severe OA: 1% vs. 3% and 8%, respectively, p&lt;0.05) and nighttime (noghttime moderate-severe OA: 10% vs. 11% and 30%, respectively, p&lt;0.05). Conclusions Daytime and nighttime apneas, both central and obstructive in nature, are highly prevalent in HF regardless of EF. Across the whole spectrum of HF, CA prevalence increases and OA decreases as left ventricular systolic dysfunction progresses, both during daytime and nighttime.

Background Chronic severe anemia is a connnon disease. Cardiac output may increase when the hemoglobin (Hb) level decreases to < 7 g/dL for 3 months or more. Alteration of left ventricular (LV) function occurs frequently in children 'With chronic severe anemia, in the {onn of concentric LV hypertrophy, LV dilatation with or v.ithout LV hypertrophy, or systolic dysfunction. Objective To examine the correlation between Hb level and alteration of LV systolic function in children with chronic severe anemia. Methods We conducted a cross-sectional study in Adam Malik Hospital from October to December 2009. Subjects were chronic severely anemic children. Left ventricular systolic function (ejection fraction/EF, fractional shortening/FS) and dimensions (left ventricular end diastolic diameter/LVEDD and left ventricular end systolic diameter/LVESD) were measured using Hitachi EUB 5500 echocardiography unit. Univariate analysis  and Pearson correlation were performed.Results Thirty children were enrolled in the study. The mean of age was 113.5 months (SD 53.24). Hb values ranged from 2.1 to 6.9 g/dL with mean value of 4.6 g/dL (SD 1.44). Mean duration of anemia was 3.9 months (SD 0.70). Chronic severe anemia was not associated \\lith decreased LV systolic function [EF 62.2% (SD 9.16), r =0.296, P=0.112; FS 33.8% (SD 7.26), r =0.115, P=0.545], nor LV dimension changes [LVEDD 40.2 mm (SD 6.85), r = -0.192, P=0.308; LVESD 26.2 mm (SD 4.98), r=-0.266, P=0.156]. Conclusion There was no correlation between Hb level in chronically anemic children and changes in LV systolic function or dimension.

Ventricular Remodelling

The glycoprotein 130 (gp130) signalling pathway is important in the development of heart failure. Cardiotrophin-1 (CT-1), a cytokine acting via the gp130 pathway, is involved in the process of ventricular remodelling following acute myocardial infarction (AMI) in animals. The aims of the present study were to examine the profile of plasma CT-1 following AMI in humans, and its relationship with echocardiographic parameters of left ventricular (LV) systolic function. Serial measurements of plasma CT-1 levels were made in 60 patients at 14-48h, 49-72h, 73-120h and 121-192h following AMI and at a later clinic visit. LV function was assessed using a LV wall motion index (WMI) score on admission (WMI-1) and at the clinic visit (WMI-2). Compared with values in control subjects (29.5±3.6fmol/ml), the plasma CT-1 concentration was elevated in AMI patients at 14-48h (108.1±15.1fmol/ml), 49-72h (105.2±19.7fmol/ml), 73-120h (91.2±14.9fmol/ml) and 121-192h (118.8±22.6fmol/ml), and at the clinic visit (174.9±30.9 fmol/ml) (P < 0.0001). Levels were higher following anterior compared with inferior AMI. For patients with anterior AMI, CT-1 levels were higher at the clinic visit than at earlier times. WMI-1 correlated with CT-1 at all times prior to hospital discharge (P < 0.05). On best subsets analysis, the strongest correlate with WMI-1 was CT-1 level at 49-72h (R2 = 20%, P < 0.05). In conclusion, plasma levels of CT-1 are elevated soon after AMI in humans and rise further in the subsequent weeks in patients after anterior infarction. CT-1 measured soon after AMI is indicative of LV dysfunction, and this cytokine may have a role in the development of ventricular remodelling and heart failure after AMI.
