Lipoprotein (a) [Lp(a)] is a well-established risk factor for cardiovascular disease independent of low-density lipoprotein-cholesterol (LDL-C). The Lp(a) concentrations were inconsistent between the immunoassays. This study aimed to investigate whether harmonization of Lp(a) measurements can be achieved using a serum panel value assigned with the IFCC-endorsed mass spectrometry-based reference measurement procedure (IFCC-MS-RMP).

We examined the association between dairy intake and all-cause, cancer, and cardiovascular disease mortality in a cohort of the general population followed up for 12 years across Japan.

Patients with chronic kidney disease (CKD) have a high incidence of atherosclerotic diseases, such as ischemic heart disease, cerebrovascular disease, and peripheral arterial disease. To prevent the incidence of atherosclerotic cardiovascular disease in patients with CKD, the pathology of arteriosclerosis should be determined. Vascular calcification is a characteristic of arteriosclerosis in patients with CKD. Recent studies have reported that coronary artery calcification is associated with acute coronary syndromes. CKD is frequently associated with heart failure. Furthermore, recent evidence suggests that coronary artery calcification affects asymptomatic myocardial ischemia. Hyperphosphatemia and calciprotein particles may be involved in the pathology of vascular calcification. Controlling the progression of vascular calcification and classical atherosclerotic risk factors is important to prevent the occurrence of atherosclerotic diseases in CKD.

Superficial erosion accounts for approximately one-third of all cases of acute coronary syndrome (ACS). Previously, we found that a nearby bifurcation is independently associated with superficial erosion; however, the effect of long-term oscillatory flow on superficial erosion remains unexplored. Endothelial-to-mesenchymal transition (EndMT) is a dynamic process in which endothelial cells acquire mesenchymal properties and, in turn, give rise to smooth muscle cell (SMC)-like cells and extracellular matrix (ECM) accumulation, similar to the autopsy pathology of superficial erosion. This finding prompted us to suspect that EndMT plays a role in the effect of chronic oscillatory flow on superficial erosion.

It is uncertain if there is a connection between subclavian steal phenomenon (SSP) and atherosclerotic stenosis in the opposite vertebral artery (VA). We aimed to explore the association between SSP and the incidence of contralateral vertebral artery stenosis (VAS) in vivo.

Few studies have investigated the impact of sleep duration at night and daytime napping on mortality from aortic disease. In this study, we examined the associations of sleep duration at night with daytime napping and mortality from aortic disease.

Atherosclerosis, a major contributor to cardiovascular diseases (CVD), remains a leading cause of global mortality and morbidity. The pathogenesis of atherosclerosis involves a complex interplay of endothelial dysfunction, chronic inflammation, lipid accumulation, and arterial stiffness. Among the various preventive strategies, physical activity has emerged as a highly effective, non-pharmacological intervention. This review examines the preventive effects of different types of exercise-specifically aerobic exercise, resistance training, and combined training-on atherosclerosis development. Drawing on evidence from landmark studies, we explore the underlying mechanisms by which these exercise modalities improve endothelial function, reduce systemic inflammation, and enhance lipid profiles, thereby mitigating the progression of atherosclerosis. Additionally, the review discusses the dose-response relationship between physical activity and cardiovascular health, the differential effects of exercise intensities, and the potential risks associated with high-intensity training. The synergistic benefits of combined aerobic and resistance training are highlighted, particularly in populations with metabolic syndrome or other high-risk conditions. Emerging trends in personalized exercise medicine and the use of wearable technology for monitoring physical activity are also addressed, underscoring the potential for tailored exercise prescriptions to maximize cardiovascular health. By integrating current research findings, this review provides insights into effective exercise strategies for reducing cardiometabolic risk and emphasizes the importance of personalized approaches in exercise interventions.

Lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic cardiovascular disease (ASCVD), and its level is genetically determined. Although guidelines and consensuses in various cardiovascular fields have emphasized the importance of Lp(a), screening for Lp(a) in China has not been well studied.

D-dimer, lipoprotein (a) (Lp(a)), and high-sensitivity C-reactive protein (hs-CRP) are known predictors of vascular events; however, their impact on the stroke prognosis is unclear. This study used data from the Third China National Stroke Registry (CNSR-III) to assess their combined effect on functional disability and mortality after acute ischemic stroke (AIS).

The effect of uric acid (UA)-lowering therapy with xanthine oxidoreductase (XOR) inhibitors on the development of cardiovascular disease requires further investigation. This study aimed to evaluate the long-term effects of febuxostat on arterial stiffness, focusing on liver function.

This review introduces "space prescribing," an innovative healthcare approach that incorporates the physical environment's role in promoting health beyond traditional clinical settings. Recognizing that individuals spend a significant amount of time outside clinical environments, this approach explores the therapeutic potential of natural and built environments in improving well-being and managing diseases, particularly cardiovascular and mental health conditions.Traditional healthcare models focus on treatments in hospital and clinic settings. However, evidence suggests that environmental factors profoundly influence health outcomes. Space prescribing recommends specific environments that encourage healthier lifestyles and enhance wellbeing. This concept includes social prescribing, in which healthcare professionals direct patients to community-based, non-medical activities such as art classes and sports, acknowledging that well-being transcends biological factors.This review also highlights "Cultural Ecosystem Services" (CES) in health through stress reduction, social connections, and physical activity. For cardiovascular health, elements such as green spaces and urban design are vital for managing conditions, such as hypertension and heart disease. Similarly, the configuration of indoor and outdoor spaces plays a crucial role in mental health. Therapeutic landscapes, including community gardens and culturally enriched urban areas, support mental health recovery, foster community engagement and reduce isolation.In conclusion, space prescribing advocates an integrated approach that considers the physical and social environments as fundamental components of health promotion. This strategy aims to mitigate health disparities and enhance the quality of life, while making health-enhancing activities accessible in urban and rural settings. Through this holistic approach, space prescribing has the potential to transform public health by strategically utilizing environmental designs to support health outcomes.

Efficacy, safety, and pharmacokinetics of the selective PPARα modulator pemafibrate as once-daily extended-release (XR) tablets were compared with those of twice-daily immediate-release (IR) tablets in patients with hypertriglyceridemia.

Stroke is a leading cause of death and disability in Japan, necessitating standardized treatment guidelines. The Japan Stroke Society (JSS) periodically revises its guidelines to incorporate new research. This review provides a short overview of acute stroke management based on JSS Guideline 2021 (revised 2023) and the Japan Stroke Data Bank (JSDB), and discusses future directions in stroke management. Acute stroke management emphasizes systemic support and complication management. Risk factor control during acute hospitalization is also crucial for preventing recurrent strokes in the chronic phase.In ischemic stroke, super-acute recanalization therapies, including intravenous thrombolysis and mechanical thrombectomy, are the most important and effective. Antiplatelet therapy, particularly aspirin and clopidogrel, is recommended for noncardiogenic stroke and high-risk transient ischemic attack. In cardioembolic stroke, early initiation of direct oral anticoagulants might be considered according to stroke severity.For brain hemorrhage, early blood pressure management is recommended. Specific reversal agents are advised for patients on anticoagulant therapy. Minimally invasive hematoma removal may improve outcomes for intracerebral hemorrhage.Subarachnoid hemorrhage treatments reported from Japan include intravenous drugs to prevent vasospasm.The JSDB revealed improvements in functional outcomes in patients with ischemic stroke over the past 20 years, although patients with hemorrhagic stroke showed no clear improvement. The evolving guidelines and research underscore the importance of stratified and timely intervention in stroke care.

In this subanalysis of the EXPAND study, we evaluated the risks and benefits of rivaroxaban plus antiplatelet therapy (APT) for patients with non-valvular atrial fibrillation (NVAF) complicated by stable coronary artery disease (CAD), ischemic stroke, or peripheral artery disease (PAD).

Cryptogenic stroke (CS) accounts for approximately one-fourth of acute ischemic strokes, with most cases derived from embolic etiologies. In 2014, embolic stroke of undetermined source (ESUS) was advocated and the efficacy of anticoagulant therapy was anticipated. However, 3 large-scale clinical trials failed to demonstrate the superiority of direct oral anticoagulants (DOACs) over aspirin, potentially due to the heterogeneous and diverse pathologies of ESUS, including paroxysmal atrial fibrillation (AF), arteriogenic sources such as nonstenotic carotid plaque and aortic complicated lesion (ACL), patent foramen oval (PFO), and nonbacterial thrombotic endocarditis (NBTE) related to active cancer.Transesophageal echocardiography (TEE) is one of the most effective imaging modalities for assessing embolic sources in ESUS and CS. The Mechanisms of Embolic Stroke Clarified by Transesophageal Echocardiography for Embolic Stroke of Undetermined Source/Cryptogenic Stroke (CHALLENGE ESUS/CS) registry is a multicenter registry that enrolled consecutive patients with CS who underwent TEE at 8 hospitals in Japan between April 2014 and December 2016. Their mean age was 68.7±12.8 years, and 455 patients (67.2%) were male. The median National Institutes of Health Stroke Scale (NIHSS) score was 2. Since 7 analyses have been conducted from each institution to date, novel and significant insights regarding embolic origins and pathophysiologies of ESUS and CS were elucidated from this multicenter registry. This review discusses the diagnosis and treatment of ESUS and CS, tracing their past and future directions. Meaningful insights from the CHALLENGE ESUS/CS registry are also referenced and analyzed.
