Item type:Publication, Utilizing natriuretic peptides for predicting heart failure risk following myocardial infarction(2025-09); ; BACKGROUND: In Mongolia, ischemic heart disease, specifically acute myocardial infarction (AMI), is a significant etiology of chronic heart failure (HF). Therefore, early recognition of the risk of HF following AMI is critically important for improving patient management. This study aimed to assess the N-terminal pro-B-type natriuretic peptide (NT-proBNP) as an early detection and prognosis of asymptomatic left ventricular (LV) dysfunction following AMI. METHODS: Patients diagnosed with AMI and in the absence of symptoms or signs of HF were prospectively included. Clinical and echocardiographic data were collected at baseline, and NT-proBNP levels were measured at admission and discharge. Patients were divided into four distinct groups based on NT-proBNP level quartiles. The study endpoint was de-novo HF at 6 months after AMI. RESULTS: A total of 120 patients with a mean age of 56.0 ± 9.2 years and 80.8% (N = 97) men were included. Higher NT-proBNP levels were associated with elevated GRACE score and diabetes, both at admission and predischarge. Additionally, higher NT-proBNP levels at admission were associated with delayed hospital presentation, whereas higher NT-proBNP levels at predischarge were associated with reduced LV global longitudinal strain. Furthermore, NT-proBNP level at predischarge was significantly associated with the development of HF 6 months after AMI, with a threshold value of 1410 pg/ml. CONCLUSION: Incorporation of NT-proBNP measurement before discharge in AMI patients could enhance risk stratification, thereby supporting its integration into routine clinical evaluation for more efficient patient management.Scopus© Citations 1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The Prevalence and Risk Factors of Chronic Heart Failure in the Mongolian Population(2023-03); ; ; BACKGROUND: The prevalence of heart failure in the Mongolian population is unknown. Thus, in this study, we aimed to define the prevalence of heart failure in the Mongolian population and to identify significant risk factors for heart failure among Mongolian adults. METHODS: This population-based study included individuals 20 years and older from seven provinces as well as six districts of the capital city of Mongolia. The prevalence of heart failure was based on the European Society of Cardiology diagnostic criteria. RESULTS: In total, 3480 participants were enrolled, of which 1345 (38.6%) participants were males, and the median age was 41.0 years (IQR 30-54 years). The overall prevalence of heart failure was 4.94%. Patients with heart failure had significantly higher body mass index, heart rate, oxygen saturation, respiratory rate, and systolic/diastolic blood pressure than patients without heart failure. In the logistic regression analysis, hypertension (OR 4.855, 95% CI 3.127-7.538), previous myocardial infarction (OR 5.117, 95% CI 3.040-9.350), and valvular heart disease (OR 3.872, 95% CI 2.112-7.099) were significantly correlated with heart failure. CONCLUSIONS: This is the first report on the prevalence of heart failure in the Mongolian population. Among the cardiovascular diseases, hypertension, old myocardial infarction, and valvular heart disease were identified as the three foremost risk factors in the development of heart failure.Scopus© Citations 2 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Assessment of global longitudinal strain and plasma natriuretic peptide in patients with asymptomatic left ventricular dysfunction(APO Society of Specialists in Heart Failure, 2021-10); ; Objective The purpose of this study was to investigate the association between global longitudinal strain (GLS) and plasma NT-proBNP for predicting left ventricular (LV) performance in asymptomatic patients after acute myocardial infarction (AMI).Material and methods We prospectively included patients with diagnosis of AMI without clinical signs and symptoms of heart failure (HF) and followed these patients for 6 mos. Baseline echocardiography was performed at admission, and follow-up echocardiography was performed after 6 mos. A normal GLS was defined as having an absolute value of ≥16 %. According to the baseline GLS, participants were divided into two groups and compared. In all participants, blood samples of plasma NT-proBNP were obtained at admission, before discharge, and 6 mo after discharge.Results The study population was consisted of 98 participants, of which 80 (81.6 %) were males, and the mean age was 56.0±9.3 years. Baseline echocardiography showed that most of the participants (60, 61.2 %) had abnormal GLS<16 %, whereas 38 (38.8 %) participants had normal or borderline GLS ≥16 %. Compared with the normal GLS group, participants with abnormal GLS had higher GRACE score, higher troponin I concentration, lower systolic blood pressure, lower mean LV ejection fraction, and decreased LV diastolic function. At 6‑mo follow-up, only LV systolic function remained significantly different between the two groups. Compared to baseline, there was a significant improvement of GLS in the abnormal GLS group at 6‑mo follow-up (p=0.04). Prevalence of complications after AMI was significantly higher in this group. There were significant differences between baseline and discharge NT-proBNP concentrations between the two groups (p<0.05). In the abnormal GLS group, there were significant correlations between baseline and discharge NT-proBNP concentrations with baseline LV systolic function. Discharge NT-proBNP concentration also correlated significantly with 6‑mo follow-up GLS. For determining the effect of baseline GLS abnormality, the areas under the ROC curve for baseline and discharge NT-proBNP concentrations were 0.73 (95 % CI 0.60-0.85, p=0.001) and 0.77 (95 % CI 0.66-0.87, p<0.001), respectively. Regarding early prediction of follow-up GLS abnormality, the area under the ROC curve for discharge NT-proBNP concentration was significantly higher 0.70 (95 % CI 0.55-0.84, p=0.016). The optimum cut-off value of discharge NT-pro-BNP was 688.5 pg / ml, with 72.4 % sensitivity and 65.4 % specificity to predict 6‑mon GLS abnormality following acute myocardial infarction.Conclusion The main finding of this study is that impaired LV GLS is associated with elevated plasma concentrations of NT-proBNP in post-AMI patients. Pre-discharge NT-proBNP concentration combined with impaired initial GLS could predict worsening LV systolic function over time in asymptomatic post-AMI patients.Scopus© Citations 1
