Summary: Coronary artery calcification is a marker of cardiovascular risk, but its association with different plaque subtypes is unclear. In stable chest pain patients, having a zero CACS does not guarantee a perfect prognosis and cannot rule out obstructive coronary artery disease, non-obstructive plaque, or adverse plaque phenotypes such as low-attenuation plaque.

Summary: A zero coronary calcium score does not definitively exclude coronary artery disease. A significant proportion of patients with zero CCS were found to have CAD. Male gender and older age (>50 years) were independently associated with the presence of noncalcified coronary plaques.

Summary: Coronary artery calcium (CAC) is associated with the risk of incident sudden cardiac death (SCD), particularly among primary prevention patients with low-intermediate risk. Stratification of SCD risk through CAC measurement can identify patients who are most likely to benefit from further downstream testing in the early stages of coronary heart disease (CHD).

Summary: It remains unclear whether a coronary artery calcium (CAC) score alone is sufficient to determine the risk of obstructive and nonobstructive atherosclerotic plaque in symptomatic patients. This study found that the characterization of atherosclerotic disease burden by CAC score is imperfect, but subgroups of CAC scores showed pathogenic patterns of disease progression and stratified long-term prognostic risk.

Summary: Coronary artery calcium (CAC) is a direct measure of an individual's coronary atherosclerotic burden. Higher levels of CAC are strongly associated with an increased risk of cardiovascular disease (CVD) events and individuals with very high CAC levels have a CVD risk similar to stable persons with a prior CVD event. Conversely, the absence of CAC (CAC=0) is associated with a low long-term risk of CVD, even among groups classified as high risk based on traditional risk factors.

Summary: The study revealed that coronary artery calcium (CAC) is prevalent in low-risk young adults, and individuals with any CAC have higher risks of cardiovascular events and myocardial infarction. Severe CAC is associated with increased risks for all outcomes including death. CAC may be useful for clinical decision-making in select young adults.

Summary: This study aimed to investigate the associations between dyslipidemia and coronary artery calcium (CAC) and developed a predictive scoring system for prognostically significant coronary calcification (PSCC). The results showed a significant association between hypertriglyceridemia and prevalent odds of PSCC, suggesting that the proposed predictive model may be a useful screening tool for PSCC.

Summary: This study explored the usage patterns of oral glucose-lowering drugs (OGLDs), particularly sulphonylureas (SUs), in Asian patients with type 2 diabetes (T2D). The findings showed that SUs, often combined with metformin, are a popular class of OGLDs in Asia. They are associated with good glycemic control and safety profiles.

Summary: This study examined the association between cumulative alcohol burden and the risk for stroke in young adults. The findings showed that young adults who engaged in moderate-to-heavy drinking had a higher risk for stroke, particularly hemorrhagic stroke. Therefore, reducing alcohol consumption should be emphasized as an important strategy for stroke prevention in young adults.

Summary: This study compared the efficacy and safety of the novel sodium-glucose cotransporter 2 inhibitor enavogliflozin with dapagliflozin in Korean patients with type 2 diabetes mellitus. The results showed that enavogliflozin and dapagliflozin had similar effects in reducing HbA1c, with no significant difference between the two groups. Additionally, the incidence of treatment-emergent adverse events was comparable between the groups. Therefore, enavogliflozin can be considered an effective treatment option for T2DM.

Summary: The study aimed to investigate the cardiovascular protection and safety of glucose-lowering therapies (GLTs). The results showed that glucagonlike peptide-1 receptor agonists (GLP-1 RAs), sodium-glucose cotransporter-2 inhibitors (SGLT-2is), and thiazolidinedione therapy can reduce the risk of major adverse cardiovascular events (MACEs). GLP-1 RAs had favorable cardiovascular and renal outcomes, SGLT-2is had significant effects on renal outcomes, and thiazolidinedione therapy increased the risk of heart failure and had no benefits on mortality.

Summary: In this study, we propose a semantic segmentation-based method for detecting atrial fibrillation (AF) by learning and classifying the morphological characteristics of fibrillation waves (F-waves). The method outperforms existing methods in localizing the target shape, enabling accurate detection of AF occurrences. Two models were designed and tested: a binary classification model (BCM) for classifying F-waves and a multiclass classification model (MCM) for classifying P, QRS, and T information. The results indicate that the proposed method performs better in AF event detection and localization, with the MCM-based method slightly outperforming the BCM-based method.

Summary: South Korea implemented active epidemiological investigations, strict isolation measures, and extensive lockdowns to control the spread of COVID-19. The situation changed dramatically with the emergence of the Omicron variant in January 2022. Despite a rapid increase in cases, the government gradually eased preventive strategies based on high vaccine coverage. Currently, the COVID-19 situation in South Korea is improving with a low mortality rate and high vaccine coverage.
