Introduction: To address cardiovascular (CV) complications and their relationship to clinical outcomes in hospitalized patients with COVID-19. Methods: A total of 196 hospitalized patients with COVID-19 were enrolled in this retrospective single-center cohort study from September 10, 2020, to December 10, 2020, with a median age of 65 years (IQR, 52-77). Follow-up continued for 3 months after hospital discharge. Results: CV complication was observed in 54 (27.6%) patients, with arrhythmia being the most prevalent (14.8%) followed by myocarditis, acute coronary syndromes, ST-elevation myocardial infarction, cerebrovascular accident, and deep vein thrombosis in 15 (7.7%), 12 (6.1%), 10(5.1%), 8 (4.1%), and 4 (2%) patients, respectively. The proportion of patients with elevated high-sensitivity troponin I, N-terminal pro-B-type natriuretic peptide, left ventricular diastolic dysfunction, and heart failure with preserved ejection fraction was greater in the CV complication group. Severe forms of COVID-19 comprised nearly two-thirds (64.3%) of our study population and constituted a significantly higher share of the CV complication group members (75.9%vs 59.9%; P=0.036). Intensive care unit admission (64.8% vs 44.4%; P=0.011) and stay (5.5days vs 0 day; P=0.032) were notably higher in patients with CV complications. Among 196patients, 50 died during hospitalization and 10 died after discharge, yielding all-cause mortality of 30.8%. However, there were no between-group differences concerning mortality. Age, heart failure, cancer/autoimmune disease, disease severity, interferon beta-1a, and arrhythmia were the independent predictors of all-cause mortality during and after hospitalization. Conclusion: CV complications occurred widely among COVID-19 patients. Moreover,arrhythmia, as the most common complication, was associated with increased mortality.

Objectives: We aimed to investigate the prevalence, risk factors and outcome of cardiac dysfunction, and explore the potential value of echocardiographic parameters in hospitalized patients with coronavirus disease 2019 (COVID-19). Background: Cardiac involvement is a prominent features in COVID-19. However, the prevalence and clinical significance of cardiac dysfunction in COVID-19 patients have not yet been well described. Methods: We studied 157 consecutive hospitalized COVID-19 patients, whose Left ventricular (LV) and right ventricular (RV) structure and function were evaluated by echocardiography. Results: RV dysfunction was found in 40 (25.5%) patients, and LV dysfunction in 28 (17.8%) patients consisting of 24 (15.3%) with heart failure with preserved ejection fraction and 4 (2.5%) with heart failure with reduced ejection fraction. Hypertension, acute respiratory distress syndrome (ARDS), high-sensitivity troponin I (hs-TNI) level and mechanical ventilation therapy was associated with cardiac dysfunction, which contributed to higher mortality (LV dysfunction: 28.6% vs 11.6%, P = 0.022; RV dysfunction: 37.5% vs 6.8%, P < 0.001, respectively). Moreover, LV and RV dysfunction were more frequent in patients with elevated hs-TNI than those without (37.5% vs 12.5 %, P = 0.001; 40.0 % vs 22.9%, P = 0.043, respectively). During hospitalization, 23 patients died. The mortality was 3.0% for patients without cardiac dysfunction and normal hs-TNI levels, 6.7% for those with cardiac dysfunction and normal hs-TNI levels, 13.3% for those without cardiac dysfunction but elevated hs-TNI levels, and 64.0% for those with cardiac dysfunction and elevated hs-TNI. In Cox analysis, RV dysfunction was independently predictor of higher mortality (hazard ratio=2.79; 95% CI: 1.10 to 7.06; P=0.031). HF, especially HFpEF, was not predictive of increased mortality. Conclusions: The prevalence of RV dysfunction was higher than that of HF. Moreover, HFpEF was more common than HFrEF. RV dysfunction is an independent predictor of higher mortality. Additionally, patients with cardiac dysfunction and elevated hs-TNI had the highest mortality, which may prompt physicians to pay attention not only to the hs-TNI level but also the cardiac dysfunction.

Left ventricular diastolic dysfunction (LVDD) is any abnormality in the filling of the left ventricle and is conventionally evaluated by analysis of the relaxation driven phase, or early diastole. LVDD has been shown to be a precursor to heart failure and the diagnosis and treatment for diastolic failure is less understood than for systolic failure. Diastole consists of two filling waves, early and late and is primarily dependent on ventricular relaxation and wall stiffness.

Từ khóa: Bệnh cơ tim giãn, rối loạn chức năng tâm trương thất trái, khuyến cáo ASE/EACVI 2016 ABSTRACT EVALUATION OF LEFT DYSTOLIC FUNCTION ACCORDING TO THE RECOMMENDATION ASE/EACVI 2016 INPATIENTS WITH DILATED CARDIOMYPAHTIES Background: Dilated cardiomyopathy is a disease of the heart muscle, characterized by dilatation of the heart chamber and a dysfunction of the left or both ventricles. It often leads to progressive heart failure, and is the leading cause of heart transplant among all cardiomyopathy. The annual rate of sudden cardiac death in dilated cardiomyopathy is 2 - 4%, with sudden death accounting for half of all deaths [9]. Echocardiography is an evaluation of a patient with dilated cardiomyopathy. There have been many studies on dilated cardiomyopathy in the world. However, there are still few studies evaluating diastolic function in patients with dilated cardiomyopathy using cardiac Doppler echocardiography. Experts around the world have made many recommendations in assessing left ventricular diastolic function, most recently is the recommendation ASE/EACVI 2016. Comparing with the 2009 EAE/ASE recommendation, the recommendation ASE/EACVI 2016 for assessment of left ventricular diastolic function has fewer parameters, so it is easier to implement and more convenient in clinical practice. Objective: Surveying left ventricular diastolic function according to the recommendation ASE/EACVI 2016 in patients with dilated cardiomyopathy by echocardiography and investigating the relationship between left ventricular diastolic function with left ventricular dilatation, heart failure NYHA, left ventricular ejection fraction, left ventricle fractional shortening. Methods: Research was designed as a cross - sectional descriptive study. Studied on 56 patients with primary dilated cardiomyopathy were hospitalized and treated at Hue Central Hospital. Results: The results showed: The mean end - diastolic and end - systolic left ventricular diameters were 66,11 ± 7,3 mm and 57,7 ± 8,02 mm. The mean left atrial diameter was 40,61 ± 7,65 mm. The mean left ventricular ejection fraction was 24,68 ± 5,97%. The mean fractional shortening of left ventricular contraction was 12,91 ± 4,55%. All patients in the study group had left ventricular diastolic dysfunction. The highest proportion is diastolic dysfunction grade II (44,6%), followed by diastolic dysfunction grade III (35,8%) and diastolic dysfunction grade I is 19,6%. There was no statistically significant relationship between the classification of left ventricular diastolic dysfunction and left ventricular systolic and diastolic diameter (p > 0.05). There is a relationship between left ventricular diastolic dysfunction and parameters of ejection fraction EF and contraction fraction FS (p < 0.005). There is a moderate positive correlation between the classification of left ventricular diastolic dysfunction and the heart failure rating according to NYHA (r = 0,445, p < 0,001). Conclusion: All patients in the study group had left ventricular diastolic dysfunction, mostly grade II and grade III diastolic dysfunction. This disorder is clearly demonstrated by the change in the parameters of the left ventricular diastolic function assessment on echocardiography according to the 2016 ASE/ EACVI recommendations, a new recommendation introduced to approach the assessment of diastolic functionmore convenient and easier way. Key words: Dilated cardiomyopathy, left ventricular diastolic dysfunction, the recommendation ASE / EACVI 2016.

Background The prevalence of undetected left ventricular diastolic dysfunction is high, especially in the elderly with comorbidities. Left ventricular diastolic dysfunction is a prognostic indicator of heart failure, in particularly of heart failure with preserved ejection fraction and of future cardiovascular and all-cause mortality. Therefore we aimed to develop sex-specific diagnostic models to enable the early identification of men and women at high-risk of left ventricular diastolic dysfunction with or without symptoms of heart failure who require more aggressive preventative strategies. Design Individual patient data from four primary care heart failure-screening studies were analysed (1371 participants, excluding patients classified as heart failure and left ventricular ejection fraction <50%). Methods Eleven candidate predictors were entered into logistic regression models to be associated with the presence of left ventricular diastolic dysfunction/heart failure with preserved ejection fraction in men and women separately. Internal-external cross-validation was performed to develop and validate the models. Results Increased age and β-blocker therapy remained as predictors in both the models for men and women. The model for men additionally consisted of increased body mass index, moderate to severe shortness of breath, increased pulse pressure and history of ischaemic heart disease. The models performed moderately and similarly well in men (c-statistics range 0.60–0.75) and women (c-statistics range 0.51–0.76) and the performance improved significantly following the addition of N-terminal pro b-type natriuretic peptide (c-statistics range 0.61–0.80 in women and 0.68–0.80 in men). Conclusions We provide an easy-to-use screening tool for use in the community, which can improve the early detection of left ventricular diastolic dysfunction/heart failure with preserved ejection fraction in high-risk men and women and optimise tailoring of preventive interventions.

Abstract- Patients with heart failure (HF) are frequently admitted for episodes of decompensation. Cardiac troponins are easily accessible biomarkers role of which for risk stratification of re-hospitalization among HF patients is less certain. We aimed to evaluate high-sensitive cardiac troponin I (hs-cTnI) levels among re-hospitalized patients with decompensated heart failure (D-HF). Consecutive subjects admitted with D-HF to 2 hospitals in Tehran, during the year 2014 were recruited. Excluded ones were patients with a suspected acute coronary syndrome or myocarditis/pericarditis, those with cardiopulmonary resuscitation/DC shock delivery, or major complications during or after hospitalization. Along with echocardiography parameters, level of hs-cTnI was checked at the first hour of hospitalization and 3 months after discharge. The patients were then categorized according to having or not having re-hospitalization during 3 months post discharge. A total of 97 patients were finally recruited. Among re-hospitalized patients, Left ventricular (LV) ejection fraction was significantly lower (38±14 % vs. 50 ± 12%; P=0.001), and LV end-systolic dimension was significantly higher (44±9 mm vs. 38±11 mm; P=0.012) compared to the other group. Moreover, levels of hs-cTnI were significantly higher among the re-hospitalized patients, both at initial visit (0.66±0.43 ng/ml vs 0.51±0.14 ng/ml, respectively; P=0.017) and at 3 months (0.59±0.48 ng/ml vs 0.48±0.23 ng/ml, respectively; P=0.030). This prospective study demonstrated that levels of hs-cTnI (both at the base and at follow up) are higher among patients who readmitted during 3 months of hospitalization for D-HF.

The beat-to-beat dynamic Starling mechanism (DSM), the dynamic modulation of stroke volume (SV) because of breath-by-breath changes in left-ventricular end-diastolic pressure (LVEDP), reflects ventricular-arterial coupling. The purpose of this study was to test whether the LVEDP-SV relationship remained impaired in heart failure with preserved ejection fraction (HFpEF) patients after normalization of LVEDP. Right heart catheterization and model-flow analysis of the arterial pressure waveform were performed while preload was manipulated using lower-body negative pressure to alter LVEDP. The DSM was compared at similar levels of LVEDP between HFpEF patients ( n = 10) and age-matched healthy controls ( n = 12) (HFpEF vs. controls: 10.9 ± 3.8 vs. 11.2 ± 1.3 mmHg, P = 1.00). Transfer function analysis between diastolic pulmonary artery pressure (PAD) representing dynamic changes in LVEDP vs. SV index was applied to obtain gain and coherence of the DSM. The DSM gain was significantly lower in HFpEF patients than in the controls, even at a similar level of LVEDP (0.46 ± 0.19 vs. 0.99 ± 0.39 ml·m−2·mmHg−1, P = 0.0018). Moreover, the power spectral density of PAD, the input variability, was greater in the HFpEF group than the controls (0.75 ± 0.38 vs. 0.28 ± 0.26 mmHg2, P = 0.01). Conversely, the power spectral density of SV index, the output variability, was not different between the groups ( P = 0.97). There was no difference in the coherence, which confirms the reliability of the linear transfer function between the two groups (0.71 ± 0.13 vs. 0.77 ± 0.19, P = 0.87). The DSM gain in HFpEF patients is impaired compared with age-matched controls even at a similar level of LVEDP, which may reflect intrinsic LV diastolic dysfunction and incompetence of ventricular-arterial coupling. NEW & NOTEWORTHY The beat-to-beat dynamic Starling mechanism (DSM), the dynamic modulation of stroke volume because of breath-by-breath changes in left-ventricular end-diastolic pressure (LVEDP), reflects ventricular-arterial coupling. Although the DSM gain is impaired in heart failure with preserved ejection fraction (HFpEF) patients, it is not clear whether this is because of higher LVEDP or left-ventricular diastolic dysfunction. The DSM gain in HFpEF patients is severely impaired, even at a similar level of LVEDP, which may reflect intrinsic left-ventricular diastolic dysfunction.

The Relationship

Left ventricular diastolic dysfunction (LVDD) and diastolic heart failure are conditions that affect the filling dynamics of the heart and affect 36% of patients diagnosed with congestive heart failure [1]. Although this condition is very prevalent, it currently remains difficult to diagnose due to inherent atrio-ventricular compensatory mechanisms including increased heart rate, increased left ventricular (LV) contractility, and increased left atrial pressure (LA). A greater comprehension of the governing flow physics in the left ventricle throughout the introduction of the heart’s compensatory mechanisms has great potential to substantially increase the understanding of the progression of diastolic dysfunction and in turn advance the diagnostic techniques.
