Abstract PDF: Cardiovascular disease is a leading cause of global mortality, necessitating effective strategies for prevention and treatment. The cardiovascular disease continuum concept highlights the progression from risk factors such as hypertension and diabetes mellitus to advanced stages, including heart failure (HF) and death. Sodium-glucose cotransporter 2 (SGLT2) inhibitors, initially developed to manage diabetes, have emerged as effective therapies across all stages of the cardiovascular disease continuum. Numerous cardiovascular outcome trials demonstrate that SGLT2 inhibitors significantly reduce major adverse cardiovascular events and hospitalizations for HF in patients with and without established atherosclerotic cardiovascular disease. Notably, SGLT2 inhibitors have shown remarkable benefits in reducing HF risk, even in patients without diabetes, including those with HF and preserved ejection fraction. Furthermore, recent studies in post–myocardial infarction patients suggest potential benefits in reducing hospitalizations for HF. Despite their widespread use, the precise mechanisms by which SGLT2 inhibitors confer cardiovascular protection remain unclear, suggesting the need for further investigation. In conclusion, SGLT2 inhibitors have revolutionized cardiovascular disease management, offering significant therapeutic potential across a broad spectrum of patients, and are expected to play an increasingly prominent role in both the prevention and treatment of cardiovascular disease.

Moyamoya disease: insights into the clinical implications of the RNF213 gene: Taedong Ok; Cardiovasc Prev Pharmacother. 2024;6(4):109-115. Published online October 31, 2024; DOI: https://doi.org/10.36011/cpp.2024.6.e14

Abstract PDF: Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by progressive stenosis of the terminal internal carotid arteries and the formation of compensatory collateral vessels, which appear as a “puff of smoke” on cerebral angiography. It is a significant cause of stroke in East Asia, with an incidence of 0.5 to 1.5 cases per 100,000 people annually. The etiology of MMD remains unclear; however, the identification of the RNF213 gene, particularly the R4810K variant, as a major susceptibility factor among the East Asian population, has provided crucial insights into the disease's pathophysiology and clinical manifestations. MMD typically presents with transient ischemic attacks, ischemic and hemorrhagic strokes, seizures, headaches, and cognitive deficits. Diagnostic criteria have evolved to emphasize advanced imaging techniques. Pathological features include fibrocellular intimal thickening, irregular undulation of the elastic lamina, and the formation of moyamoya vessels. The mutation in the RNF213 gene impairs the degradation of proteins involved in vessel development, leading to abnormal angiogenesis. Genotype-phenotype studies indicate that the RNF213 variant is associated with an earlier onset, transient ischemic attacks, infarctions, and involvement of the posterior cerebral artery, although its effects vary between regions. Additionally, the homozygous RNF213 variant consistently correlates with an earlier age of onset and a higher risk of cerebral infarction. However, further research is necessary to fully understand its long-term impacts and its relationship with revascularization outcomes. Ongoing research is crucial to fully comprehend the pathophysiology and genetics of MMD, improve prognostic predictions, and develop novel therapies.

Abstract PDF: The UK Prospective Diabetes Study was the first study to investigate the effectiveness of glycemic control in patients with type 2 diabetes. Since then, many studies have evaluated the impact of intensive glycemic control on diabetes-related morbidities and mortality. The results of these studies were intended to change the paradigm for controlling glycated hemoglobin and preventing diabetes-related complications, but the beneficial outcomes were limited to microvascular diseases rather than diabetes-related cardiorenal diseases and deaths. This has emphasized the need for comprehensive management of other risk factors (hypertension, dyslipidemia, renal failure, etc.) in addition to hyperglycemia to prevent atherosclerotic cardiovascular diseases and end-stage renal disease in type 2 diabetes. Since 2008, clinical trials to demonstrate cardiovascular safety have shown a beneficial effect of sodium-glucose transporter 2 inhibitors or glucagon-like peptide-1 receptor agonists on macrovascular or renal complications in patients with type 2 diabetes. Recently, major societies around the world including the Korean Diabetes Association, have shifted the goals of diabetes management from the typical glucocentric view to cardiorenal outcome-oriented (organ protection) care, which has been widely accepted and is gradually applied to primary care.

Relationship between autonomic and peripheral neuropathies and cardiovascular outcomes in diabetes: Jae-Seung Yun; Cardiovasc Prev Pharmacother. 2024;6(4):123-127. Published online October 31, 2024; DOI: https://doi.org/10.36011/cpp.2024.6.e17

Abstract PDF: This review explores the complex relationship between diabetic neuropathy and cardiovascular disease (CVD). Neuropathy, a common complication of type 1 and type 2 diabetes, is divided into autonomic and peripheral types, each impacting cardiovascular health. Cardiovascular autonomic neuropathy, a form of autonomic neuropathy, is associated with various CVD complications, including arrhythmias, impaired nocturnal blood pressure regulation, and increased mortality. The prevalence of cardiovascular autonomic neuropathy varies depending on the type and duration of diabetes and is influenced by factors like glycemic control and metabolic stress. Peripheral polyneuropathy, which is often linked to diabetic foot disease, is also correlated with elevated CVD risk; research suggests shared pathophysiological mechanisms between peripheral neuropathy and cardiovascular conditions. Screening for neuropathies using tools like the Michigan Neuropathy Screening Instrument and heart rate variability analyses can facilitate early detection of CVD risk. Additionally, emerging technologies, like deep learning models, have demonstrated promise in detecting early cardiovascular patterns associated with autonomic neuropathy through electrocardiogram analysis. These findings underscore the value of integrating novel diagnostic approaches for early intervention. As CVD represents a leading cause of death among patients with diabetes, this article emphasizes the need for thorough assessment and proactive management of neuropathy to mitigate cardiovascular risk. The review recommends a multidisciplinary approach to diabetes care, including early screening, accurate risk stratification, and targeted therapeutic strategies to prevent or slow the progression of CVD in patients with autonomic and peripheral neuropathies. Further research is warranted to clarify the optimal intervention strategies for reducing CVD risk in these populations.

Use of dual-energy x-ray absorptiometry for body composition in chronic disease management: Tae Nyun Kim; Cardiovasc Prev Pharmacother. 2024;6(4):128-134. Published online October 31, 2024; DOI: https://doi.org/10.36011/cpp.2024.6.e13

Abstract PDF: As individuals age or contend with chronic diseases, shifts in body composition often emerge, characterized by a loss of muscle mass and an increase in fat mass, even among those with stable body weight. Both obesity and sarcopenia are key drivers of frailty, disability, and heightened morbidity and mortality. The simultaneous decline in skeletal muscle and accumulation of visceral fat can work synergistically, magnifying their detrimental effects on physical function and metabolic health. Today, dual-energy x-ray absorptiometry (DEXA) is widely recognized as one of the most versatile imaging techniques for assessing not only osteoporosis but also sarcopenia and obesity. Whole-body DEXA facilitates comprehensive analysis, offering detailed insights into fat mass, non-bone lean mass, and bone mineral content at both total and regional levels. DEXA is highly valued for its accuracy, reproducibility, speed, affordability, and low radiation exposure. Furthermore, advancements in DEXA technology and software now allow for precise estimation of visceral adipose tissue. This review underscores the clinical applications of whole-body DEXA, focusing on the use of muscle and fat mass indices in diagnosing low muscle mass, sarcopenia, and sarcopenic obesity, aligned with the latest research and guidelines.
