Objective: This study aimed to evaluate the effect of implementing the consensus statement from the Asian Society of Cardiovascular Imaging-Practical Tutorial 2020 (ASCI-PT 2020) on the reliability of cardiac MR with late gadolinium enhancement (CMR-LGE) myocardial viability scoring between observers in the context of ischemic cardiomyopathy. Materials and Methods: A total of 17 cardiovascular imaging experts from five different countries evaluated CMR obtained in 26 patients (male:female, 23:3; median age [interquartile range], 55.5 years [50–61.8]) with ischemic cardiomyopathy. For LGE scoring, based on the 17 segments, the extent of LGE in each segment was graded using a five-point scoring system ranging from 0 to 4 before and after exposure according to the consensus statement. All scoring was performed via webbased review. Scores for slices, vascular territories, and total scores were obtained as the sum of the relevant segmental scores. Interobserver reliability for segment scores was assessed using Fleiss’ kappa, while the intraclass correlation coefficient (ICC) was used for slice score, vascular territory score, and total score. Inter-observer agreement was assessed using the limits of agreement from the mean (LoA). Results: Interobserver reliability (Fleiss’ kappa) in each segment ranged 0.242–0.662 before the consensus and increased to 0.301–0.774 after the consensus. The interobserver reliability (ICC) for each slice, each vascular territory, and total score increased after the consensus (slice, 0.728–0.805 and 0.849–0.884; vascular territory, 0.756–0.902 and 0.852–0.941; total score, 0.847 and 0.913, before and after implementing the consensus statement, respectively. Interobserver agreement in scoring also improved with the implementation of the consensus for all slices, vascular territories, and total score. The LoA for the total score narrowed from ± 10.36 points to ± 7.12 points. Conclusion The interobserver reliability and agreement for CMR-LGE scoring for ischemic cardiomyopathy improved when following guidance from the ASCI-PT 2020 consensus statement.

The Asian Society of Cardiovascular Imaging-Practical Tutorial (ASCI-PT) is an instructional initiative of the ASCI School designed to enhance educational standards. In 2021, the ASCI-PT was convened with the goal of formulating a consensus statement on the assessment of coronary stenosis and coronary plaque using coronary CT angiography (CCTA). Nineteen experts from four countries conducted thorough reviews of current guidelines and deliberated on eight key issues to refine the process and improve the clarity of reporting CCTA findings. The experts engaged in both online and on-site sessions to establish a unified agreement. This document presents a summary of the ASCI-PT 2021 deliberations and offers a comprehensive consensus statement on the evaluation of coronary stenosis and coronary plaque in CCTA.

INTRODUCTIONAtherosclerotic cardiovascular disease is a global health burden. However, there are heterogeneities among countries or regions in the risk factors and clinical manifestations of atherosclerotic diseases as well as management patterns.

METHODSWe collected data from 25 centres in Thailand. Patients with documented coronary artery disease, cerebrovascular disease or peripheral arterial disease, or with at least three atherosclerosis risk factors were enrolled between April 2011 and March 2014. Data on demographics, atherosclerosis risk factors and the management pattern of risk factors, including laboratory findings, were recorded.

RESULTSIn total, 9,390 patients, including 4,861 patients with established atherosclerotic disease and 4,529 patients with multiple risk factors, were enrolled. The modifiable risk factors, other than current smoking habit (5.3%), were common: hypertension (83.8%), dyslipidaemia (85.9%) and diabetes mellitus (57.4%). A majority of patients with hypertension (96.3%), dyslipidaemia (93.8%) and diabetes mellitus (78.5%) received medications for their conditions. Antiplatelet agents were given to 73.9% of patients. The undertreatment rate of cardiovascular risk factors, such as blood pressure, low-density lipoprotein cholesterol, haemoglobin A1c and smoking status, was 35.8%, 59.0%, 45.3% and 5.3%, respectively.

CONCLUSIONConventional atherosclerosis risk factors were common among Thai patients with established atherosclerotic disease. Even though most of the patients received recommended treatments according to established guidelines, a significant proportion of them were undertreated for atherosclerosis risk factors.

INTRODUCTION: Data 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. METHODS: Patients 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. RESULTS: A 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). CONCLUSIONS The 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.

INTRODUCTION: International normalised ratio (INR) control is an important factor in patients with non-valvular atrial fibrillation (NVAF) being treated with warfarin. INR control was previously reported to be poorer among Asians compared to Westerners. We aimed to validate the SAMe-TT2R2 score for prediction of suboptimal INR control (defined as time in therapeutic range [TTR] < 65% in the Thai population) and to investigate TTR among Thai NVAF patients being treated with warfarin. METHODS: INR data from patients enrolled in a multicentre NVAF registry was analysed. Clinical and laboratory data was prospectively collected. TTR was calculated using the Rosendaal method. Baseline data was compared between patients with and without suboptimal INR control. Univariate and multivariate analyses were performed to identify variables independently associated with suboptimal INR control. RESULTS: A total of 1,669 patients from 22 centres located across Thailand were included. The average age was 69.1 ± 10.7 years, and 921 (55.2%) were male. The mean TTR was 50.5% ± 27.5%; 1,125 (67.4%) had TTR < 65%. Univariate analysis showed hypertension, diabetes mellitus, heart failure, renal disease and SAMe-TT2R2 score to be significantly different between patients with and without optimal TTR. The SAMe-TT2R2 score was the only factor that remained statistically significant in multivariate analysis. The C-statistic for the SAMe-TT2R2 score in the prediction of suboptimal TTR was 0.54. CONCLUSION SAMe-TT2R2 score was the only independent predictor of suboptimal TTR in NVAF patients being treated with warfarin. However, due to the low C-statistic, the score may have limited discriminative power.
