INTRODUCTIONData on the long-term outcomes of Asian patients admitted for acute decompensated heart failure is scarce. The objectives of this study were to determine short-term, intermediate-term and long-term survival among patients admitted for acute decompensated heart failure in Thailand, and to identify factors independently associated with increased mortality.METHODSPatients who were admitted with a primary diagnosis of heart failure were enrolled in the Thai Acute Decompensated Heart Failure Registry (ADHERE) from 18 hospitals located across Thailand during 2006. Medical record data was collected according to ADHERE protocol. Mortality data was collected from death certificates on file at the Thailand Bureau of Registration Administration.RESULTSA total of 1,451 patients were included. The mean age of the patients was 63.7 ± 14.4 years, and 49.7% were male. One-year, five-year and ten-year mortality rates in Thai patients admitted for acute decompensated heart failure were 28.0%, 58.2% and 73.3%, respectively. Independent predictors of increased mortality were identified. There were more cardiovascular-related deaths than non-cardiovascular-related deaths (54.6% vs. 45.4%, respectively).CONCLUSIONSThe ten-year mortality rate in Thai patients admitted for acute decompensated heart failure was 73.3%. Many factors were found to be independently associated with increased mortality, including left ventricular ejection fraction. 相似文献

BACKGROUND: Data available on the correlation of N-terminal probrain natriuretic peptide (NT-proBNP) levels and right ventricular (RV) function in patients with coronary artery disease (CAD) are limited. OBJECTIVE: To determine the relation between plasma NT-proBNP and RV function in patients with CAD and abnormal left ventricular (LV) wall motion. METHODS: This is a cross-sectional study. We studied 176 patients with CAD and abnormal LV wall motion. All patients underwent cardiac magnetic resonance imaging for the assessment of LV and RV function and plasma NT-proBNP analysis on the same day. Multivariable analysis was performed to evaluate the independent factors associated with RV dysfunction. Receiver-operating characteristic analysis was used to assess the use of NT-proBNP levels for the diagnosis of LV and RV dysfunction. RESULTS: Average LV ejection fraction (LVEF) and RV ejection fraction were 37.6 and 52.0%, respectively. Median levels of NT-proBNP were 978 pg/ml. Log NT-proBNP levels had a positive correlation with age, LV and RV volume, LV and RV mass, and had a negative correlation with body size, creatinine clearance, LVEF, and RV ejection fraction. From a multivariable analysis, log NT-proBNP levels and LVEF were independently associated with RV dysfunction. From receiver-operating characteristic analysis, NT-proBNP at the levels of 1706 and 378 pg/ml was shown to detect RV dysfunction and LV dysfunction at an accuracy of 80.7 and 77.8% and area under the curve of 0.837 and 0.765, respectively. CONCLUSION: NT-proBNP levels can be used to diagnose RV dysfunction in patients with CAD and abnormal LV wall motion. 相似文献

Domestic ducks and H5N1 influenza epidemic, Thailand 总被引:3,自引:0,他引:3

In addition to causing 12 human deaths and 17 cases of human infection, the 2004 outbreak of H5N1 influenza virus in Thailand resulted in the death or slaughter of 60 million domestic fowl and the disruption of poultry production and trade. After domestic ducks were recognized as silent carriers of H5N1 influenza virus, government teams went into every village to cull flocks in which virus was detected; these team efforts markedly reduced H5N1 infection. Here we examine the pathobiology and epidemiology of H5N1 influenza virus in the 4 systems of duck raising used in Thailand in 2004. No influenza viruses were detected in ducks raised in "closed" houses with high biosecurity. However, H5N1 influenza virus was prevalent among ducks raised in "open" houses, free-ranging (grazing) ducks, and backyard ducks. 相似文献

BACKGROUND: Recent reports have shown abnormalities on cardiac magnetic resonance imaging (MRI) in patients with right ventricular outflow tract (RVOT) tachycardia. Objectives: Objectives of this study were to demonstrate abnormalities on MRI and signal-averaged ECG (SAECG) in patients with RVOT tachycardia and their correlation with the outcome of radiofrequency (RF) ablation. METHODS: We studied 41 patients with symptomatic RVOT tachycardia and 15 controls. SAECG and cardiac MRI were performed on every subject. An evaluation of structural abnormality, chamber size, function, and wall motion abnormality of the left and right ventricle was performed by MRI. Focal wall thinning was evaluated by the black blood technique and fatty infiltration was evaluated by the T1 image with and without fat suppression. RESULTS: MRI abnormalities were demonstrated in 24 (58.5%) patients with RVOT tachycardia. The abnormalities included localized wall bulging in 22 (53.7%), focal wall thinning in 10 (24.4%), and fatty replacement in 9 (22%) patients. MRI abnormality was found in only one patient in the control group (P < 0.001). Late potentials from SAECG were demonstrated in six (10.7%) patients but none in the controls (P = 0.117). Among 29 patients who underwent RF ablation, 3 patients had a failed procedure and 3 having arrhythmia recurrence needed repeated ablation. MRI abnormalities and late potentials were associated with an unfavorable outcome of RF ablation. CONCLUSIONS: MRI abnormalities were frequently found in patients with RVOT tachycardia. MRI abnormalities and late potentials can predict outcomes of RF ablation. 相似文献

Derived 12-lead electrocardiogram in the assessment of ST-segment deviation and cardiac rhythm 总被引:5,自引:0,他引:5
BACKGROUND: There are little data on the validation of 12-lead electrocardiogram (ECG) derived by the EASI lead system used for continuous monitoring in critical care settings. OBJECTIVE: The objectives of this study were to determine the accuracy of 12-lead ECG derived by the EASI lead system in the detection of ST-segment deviation and cardiac rhythm compared with the standard 12-lead ECG. METHODS: All patients admitted to the coronary care unit were studied. Kappa statistics was used to calculate the agreement between both ECG systems in the determination of cardiac rhythm and premature ventricular complex morphology. ST-segment analysis was performed in patients with acute coronary syndromes. Pearson correlation was used to correlate the ST-segment deviation between both techniques. The sensitivity and specificity of the determination of significant ST-segment deviation by the EASI lead system were calculated. RESULTS: There were a total of 282 patients enrolled in this study. There was a complete agreement in the interpretation of cardiac rhythm between the 2 methods (kappa = 1). Analysis of ST-segment deviation of 12-lead ECG also showed a significant correlation (correlation coefficient varied from 0.62 in lead I to 0.823 in lead aVF with a P value of <.001 in all leads) between the 2 methods with very high sensitivity and specificity in the detection of significant ST-segment elevation and depression. CONCLUSION: The 12-lead ECG derived by the EASI lead system is an accurate and reliable information for the assessment of ST-segment deviation and cardiac rhythm in critically ill patients. 相似文献
