730 Effect of the rate of D dimer level increase on the process of left ventricular myocardial remodeling

Abstract Aims myocardial involvement in the course of Coronavirus disease 2019 (COVID-19) pneumonia has been reported, though not fully characterized yet. Aim of the present study is to undertake a joint evaluation of hs-Troponin and natriuretic peptides (NP) in patients hospitalized for COVID-19 pneumonia. Methods and results in this multicenter observational study, we analyzed data from n = 111 COVID-19 patients admitted to dedicated “COVID-19” medical units. Hs-Troponin was assessed in n = 103 patients and NP in n = 82 patients on admission; subgroups were identified according to values beyond reference range. increased hs-Troponin and NP were found in 38% and 56% of the cases respectively. As compared to those with normal cardiac biomarkers, these patients were older, had higher prevalence of cardiovascular diseases (CVD) and more severe COVID-19 pneumonia by higher CRP and D-dimer and lower PaO2/FIO2. Two-dimensional echocardiography performed in a subset of patients (n = 24) showed significantly reduced left ventricular ejection fraction in patients with elevated NP only (p = 0.02), whereas right ventricular systolic function (tricuspid annular plane systolic excursion) was significantly reduced both in patients with high hs-Troponin and NP (p = 0.022 and p = 0.03 respectively). On multivariable analysis, independent associations were found of hs-Troponin with age, PaO2/FIO2 and D-dimer (B = 0.419, p = 0.001; B=-0.212, p = 0.013 and B = 0.179, p = 0.037 respectively), and of NP with age and previous CVD (B = 0.480, p < 0.001 and B = 0.253, p = 0.001 respectively). In patients with in-hospital mortality (n = 23, 21%) hs-Troponin and NP were both higher (p = 0.001 and p = 0.002 respectively), while increasing hs-troponin and NP were associated with worse in-hospital prognosis [OR 4.88 (95% CI 1.9-12.2), p = 0.001 (adjusted OR 3.1 (95% CI 1.2-8.5), p = 0.025) and OR 4.67 (95% CI 2-10.8), p < 0.001 (adjusted OR 2.89 (95% CI 1.1-7.9), p = 0.04) respectively]. Receiver operator characteristic curves showed good ability of hs-Troponin and NP in predicting in-hospital mortality (AUC = 0.869 p < 0.001 and AUC = 0.810, p < 0.001 respectively). Conclusion myocardial involvement at admission is common in COVID-19 pneumonia and associated to worse prognosis, suggesting a role for cardiac biomarkers assessment in COVID-19 risk stratification. Independent associations of hs-Troponin with markers of disease severity and of NP with underlying CVD might point towards existing different mechanisms leading to their elevation in this setting.

Left ventricular (LV) pressure (PO) or volume (VO) overload is accompanied by myocardial remodeling, but mechanisms that contribute to this progressive remodeling process remain unclear. The matrix metalloproteinases (MMPs) contribute to tissue remodeling in a number of disease states. This study tested the hypothesis that increased MMP expression and activity occur after the induction of an LV overload, which is accompanied by a loss of endogenous MMP inhibitory control. LV MMP zymographic activity and species abundance were measured in dogs under the following conditions: acute PO induced by ascending aortic balloon inflation (6 h, n = 9), prolonged PO by aortic banding (10 days, n = 5), acute VO through mitral regurgitation secondary to chordal rupture (6 h, n = 6), prolonged VO due to mitral regurgitation (14 days, n = 7), and sham controls ( n = 11). MMP zymographic activity in the 92-kDa region, indicative of MMP-9 activity, increased over threefold in acute PO and VO and fell to control levels in prolonged PO and VO. The MMP-9 activity-to-abundance ratio increased by over fourfold with acute VO and twofold in acute PO, suggesting a loss of inhibitory control. Endogenous MMP inhibitor content was unchanged with either PO or VO. Interstitial collagenase (MMP-1) content decreased by 50% with acute VO but not with acute PO. Stromelysin (MMP-3) levels increased by 40% with acute VO and increased by 80% with prolonged PO. Although changes in LV myocardial MMP activity and inhibitory control occurred in both acute and prolonged PO and VO states, these changes were not identical. These results suggest that the type of overload stimulus may selectively influence myocardial MMP activity and expression, which in turn would affect the overall LV myocardial remodeling process in LV overload.

Aim To study the clinical value of markers for myocardial electrical instability in combination with echocardiographic parameters for predicting the risk of cardiovascular complications (CVC) in the postinfarction period.Material and methods This study included 118 patients with ST segment elevation myocardial infarction (STEMI) and hemodynamically significant stenosis of one coronary artery. A percutaneous coronary intervention (PCI) with stenting of the infarct-related artery was performed for all patients. On day 7-9 and at 24 and 48 weeks after the treatment, ECG Holter monitoring was performed, which included analyses of ventricular late potentials, dispersion of QT interval duration, heart rate turbulence (HRT) and variability (HRV), and heart chronotropic load (HCL). At baseline and during postinfarction week 12, all patients underwent echocardiography with calculation of indexes of end-diastolic volume (iEDV) and end-systolic volume (iESV) to verify the signs of left ventricular (LV) myocardial remodeling. The criteria for LV pathological remodeling included increases in iEDV >20 % and/or iESV >15 % at 12 weeks after STEMI. The group without remodeling, R(-), consisted of 79 (67 %) patients and the group with signs of LV pathological remodeling, R(+), consisted of 39 (33 %) patients. Quality of life and achieved endpoints were evaluated during 144 weeks.Results By week 48 in group R(-), the stabilization of electrical processes in the myocardium was more pronounced as indicated by a decrease in HFLA by 12 % (р=0.004) and by a fourfold increase in RMS (р=0.047). Only in this group, the baroreflex sensitivity restored; pathological ТРС decreased from 20 to 5% (p=0.002) by the end of the active treatment. Stabilization of the repolarization phase duration in various parts of the myocardium was more active in patients without pathological remodeling as shown by decreases in disp QTa (р=0.009), disp QTe (р=0.03), sd QTa (р=0.006), and sd QTe (р=0.009). This was not observed in the group R(+). The recovery of vagosympathetic balance due to leveling the sympathetic component also was more effective in the group R(-), which was reflected in increased spectral and temporal HRV indexes (р<0.05). Both groups showed reduced HCL values at 24 weeks (р=0.047 and р=0.006); however, the HCL regression remained also at 48 weeks only in the group R(-) (р=0.006). Group R(-) patients reported higher quality of life (р=0.03) than group R(+) patients. Endpoints were achieved more frequently in the group R(+): 87.1 % vs. 27.8 % (odds ratio, 11.8; 95 % confidence interval, 4.6–30.8; р=0.00001).Conclusion Pathological myocardial remodeling in early postinfarction period is associated with electrophysiological instability of the myocardium, which results in the development of CVC and low quality of life in patients with STEMI.

Background: Acute coronary syndromes (ACSs) are the primary cause of mortality worldwide. The aim of the study was to assess the as‑sociations of serum fibrinogen and plasma D‑dimer levels with angiographic severity of atherosclerotic lesions as well as the presence of in‑hospital complications and complications at 30‑day follow‑up in patients with ACS. Methods: This was a prospective study including 107 patients with ACS. Severity of CAD was assessed by the Gensini score. Correlations of D‑dimer and fibrinogen levels with complica‑tions such as heart failure, arrhythmia, recurrent angina, and cardiac death were assessed using the Pearson correlation coefficient and the receiver operating characteristic curve analysis. Results: The mean age of patients was 61±10.9 years. Mean serum fibrinogen levels were higher in individuals with severe left ventricular (LV) dysfunction than in those with moderate and mild LV dysfunction (444 mg/dl, 404 mg/dl, and 330 mg/dl, respectively). Similarly, the mean plasma D‑dimer level was higher in individuals with severe ACS (1.03 μg/ml) than in those with moderate (1.88 μg/ml) and mild ACS (3.5 μg/ml). Conclusion: Our study revealed that patients with higher serum fibrinogen levels tend to have more severe ACS, greater LV dysfunction, and a higher rate of complications. Therapies aimed at reducing fibrinogen levels might help reduce mortality and morbidity in patients with ACS.

Data of echocardiographic characteristics of 59 children 10-11 years old, involved in football is presented in article. Depending on the duration of sports activities the children were divided into 3 groups: group 1 - children who play football up to 3 years (24 children), Group 2 - children who play football from 3 to 5 years (23 children), Group 3 - training duration over 5 years (12 children). It was found that the linear sizes of the heart were not significantly different in the groups studied, which may indicate that myocardial remodeling as cardiac adaptation to sporting loads takes more time. It was revealed that more trained children (group 3) have significantly higher left ventricular ejection fraction compared with group 1 (p = 0.05) and Group 2 (p = 0.0051).

Background: Cardiomyopathies (CMPs) due to myocytes involvement are among the leading causes of sudden adolescent death and heart failure. During the COVID-19 pandemic, there are limited data available on cardiac complications in patients with COVID-19, leading to severe outcomes.Methods: We conducted a systematic search in Pubmed/Medline, Web of Science, and Embase databases up to August 2020, for all relevant studies about COVID-19 and CMPs.Results: A total of 29 articles with a total number of 1460 patients were included. Hypertension, diabetes, obesity, hyperlipidemia, and ischemic heart disease were the most reported comorbidities among patients with COVID-19 and cardiomyopathy. In the laboratory findings, 21.47% of patients had increased levels of troponin. Raised D-dimer levels were also reported in all of the patients. Echocardiographic results revealed mild, moderate, and severe Left Ventricular (LV) dysfunction present in 17.13, 11.87, and 10% of patients, respectively.Conclusions: Cardiac injury and CMPs were common conditions in patients with COVID-19. Therefore, it is suggested that cardiac damage be considered in managing patients with COVID-19.

Background: D-dimer is a sensitive biomarker for cancer-associated thrombosis, but little is known about its significance on cancer therapeutics-related cardiac dysfunction (CTRCD). Methods and Results: Consequtive 202 patients planned for cardiotoxic chemotherapy (anthracyclines, monoclonal antibodies, tyrosine kinase inhibitors, and proteasome inhibitors) were enrolled and followed up for 12 months. Cancer types were as follows: breast cancer (n=112), lymphoma (n=37), ovarian or uterine cancer (n=18), leukemia (n=13), multiple myeloma (n=6), bone cancer (n=4), and others (n=12). All patients underwent echocardiography and blood test at baseline, 3-month, 6-month, and 12-month. The patients were divided into 2 groups based on the value of D-dimer (>1.5 μg/ml or ≦1.5 μg/ml) at baseline before chemotherapy: High D-dimer group (n=52) and Low D-dimer group (n=150). At baseline, left ventricular ejection fraction (LVEF), left ventricular end-systolic volume index, and B-type natriuretic peptide levels were similar between two groups. Time-dependent decrease in LVEF was observed after chemotherapy in high D-dimer group (baseline, 66±5%; 3-month, 63±7%; 6-month, 62±7%; 12-month 62±6%; P=0.005, figure), but not in low D-dimer group. Time-dependent increase in troponin I was similarly observed after chemotherapy in both groups. The occurrence of CTRCD was higher in high D-dimer group than in low D-dimer group (11.5% vs. 4.0%, P=0.048). When we set the cut-off value of baseline D-dimer at 1.65 μg/ml from ROC analysis, sensitivity, specificity, and area under the curve to predict CTRCD were 50%, 77%, and 0.679, respectively. Multivariable logistic analysis revealed that baseline D-dimer was an independent factor to predict the decrease in LVEF more than 10% after cardiotoxic chemotherapy (odds ratio 1.210, 95% confidence interval [1.020-1.440], P=0.025). Conclusion: Baseline D-dimer is a pivotal parameter to predict CTRCD.

Background: Acute kidney injury (AKI) detected after admission to coronary care unit (CCU) is associated with very poor outcomes. We prospectively investigated the prognostic value of a combination of AKI and high plasma D-dimer levels for 1-year mortality in patients hospitalized to CCUs. Methods: D-dimer, N-terminal pro-B-type natriuretic peptide (NT-proBNP), and high-sensitive C-reactive protein (hsCRP) levels were measured in 1228 patients on admission to CCUs, of whom 56% had decompensated heart failure and 38% had acute coronary syndrome. AKI was defined as an increase of >25% in creatinine from baseline or an absolute increase of ≥0.5 mg/dL within 48 h after admission. Left ventricular ejection fraction (LVEF) and E/e’ ratio were estimated using echocardiography with tissue Doppler imaging. Results: AKI was detected in 163 (13%) patients. During 1-year follow-up period, there were 149 (12%) deaths. The patients who died were older (median: 77 vs. 73 years; p < 0.0001) and exhibited higher D-dimer (2.7 vs. 1.3 μg/mL; p < 0.0001), NT-proBNP (5495 vs. 1525 pg/mL; p < 0.0001), and hsCRP levels (0.92 vs, 0.26 mg/L; p < 0.0001) and E/e’ ratio (15.0 vs. 13.2; p = 0.006). They also had a higher incidence of AKI (26% vs. 12%; p < 0.0001) and lower LVEF (39% vs. 49%; p < 0.0001) and estimated glomerular filtration rate (45 vs. 62 mL/min/1.73 m 2 ; p < 0.0001) than patients who survived. Multivariate Cox regression analysis, including 12 clinical, biochemical, and echocardiographic variables, identified AKI (relative risk: 1.79; p = 0.008) and increased D-dimer level (relative risk: 1.83 per 10-fold increment; p = 0.002) as independent predictors of 1-yeart mortality. The combined assessment of AKI and D-dimer quartiles was significantly associated with 1-year mortality rates (Figure). Conclusions: The combined assessment of AKI and high D-dimer levels may be useful for evaluating the risk of 1-year mortality in patients admitted to CCUs.
