Summary: Hematopoiesis is the process of blood production, but the susceptibility of hematopoietic stem cells to mutations can lead to clonal hematopoietic disorders. Clonal hematopoiesis is associated with aging, where mutant stem cells produce a small portion of mature immune cells. People with clonal hematopoiesis have an increased risk of mortality due to cardiovascular disease.

Summary: This review provides a comprehensive examination of existing evidence on mCA disease and mortality associations, utilizing genotype array intensity data from large populations. A framework for interpreting these associations in the context of biases specific to mCA studies is presented. The goal is to motivate well-designed mCA studies that can enhance understanding of aging effects and accelerate translational applications for public health improvement.

Summary: Recent studies have highlighted the important roles of telomere, CHIP, and atherosclerosis in cardiovascular disease. Telomere attrition is associated with CHIP, commonly observed in elderly patients. Telomeres, CHIP, and atherosclerosis contribute to chronic inflammation and proinflammatory cytokine expression.

Summary: Age-related clonal expansion of cells with chromosomal alterations is an important aspect of clonal haematopoiesis. This study investigated the association between widely measured serum biomarkers and clonal expansion of cells with chromosomal alterations, providing new insights into the molecular changes that promote acquisition and expansion of these cells. The results showed that commonly measured serum biomarkers related to lipid levels, sex hormones, blood sugar homeostasis, inflammation and immune function, vitamins and minerals, kidney function, and liver function were associated with clonal expansion. The findings suggest that the mechanisms underlying these diseases may be related to clonal cell proliferation and expansion.

Summary: Mosaic chromosomal alterations (mCAs) in blood are predictive markers for human diseases, and their rates vary in genetically diverse populations. Whole-genome sequencing data analysis reveals that individuals of European ancestry have the highest rates of autosomal mCAs and the lowest rates of chromosome X mCAs.

Summary: Clonal hematopoiesis is a prevalent disease associated with all-cause death and has strong associations with cardiovascular disease. This review summarizes the latest research on clonal hematopoiesis, discusses its strong association with accelerated cardiovascular disease, and rationalizes the intervention of clonal hematopoiesis based on existing evidence, which may be beneficial for future treatment.

Summary: Genetic screening in young stroke patients revealed a 3-fold higher prevalence of clonal hematopoiesis compared to the general population. About 4.4% of patients had high-risk clonal hematopoiesis and 1% had covert myeloproliferative neoplasms, requiring specific treatment. These findings highlight the diagnostic and therapeutic value of genetic screening in young stroke patients.

Summary: The emergence of novel immunotherapies for myelodysplastic syndrome (MDS) has led to the need for a comprehensive understanding of the immune system in the bone marrow (BM) and its impact on prognosis. This study found that both healthy donors and MDS patients have high levels of lymphocytes with PD-1 expression and myeloid cells with PD-1L expression, indicating a potential role of checkpoint systems in the BM. Complex alterations in checkpoint pathways were identified in MDS patients, and the checkpoint profile was found to have independent prognostic significance for overall survival.

Summary: This study found that mosaic chromosomal alterations (mCAs) increase with age and play a significant role in aging-related diseases and mortality. The distribution of mCAs in centenarians and individuals with familial longevity was investigated. The results showed that the accumulation of mCAs reaches a plateau at around 102 years, and centenarians and their offspring have fewer mCAs compared to controls. Genetic factors such as APOE E4 allele and gender also influence the occurrence of mCAs. mCAs are associated with increased risk of cancer, dementia, and possibly mortality.

Summary: Clonal hematopoiesis of indeterminate potential (CHIP) is a common bone marrow abnormality caused by age-related DNA mutations, which leads to the production of proinflammatory immune cells. These immune cells aggravate atherosclerotic cardiovascular disease and may contribute to heart failure. The mechanisms involved suggest that proinflammatory macrophages and an inflammasome-dependent immune response play a central role. Intracardiac inflammation can decrease cardiac function and induce cardiac fibrosis, even without the presence of atherosclerotic cardiovascular disease. The pathophysiology and consequences of CHIP can vary depending on the implicated genes and subgroups of heart failure patients.

Summary: The clonal hematopoiesis of indeterminate potential (CHIP) refers to the presence of detectable somatic mutations in genes associated with hematologic cancers in individuals without any apparent evidence of such conditions. Studies have shown that the frequently altered genes in CHIP are also associated with an increased risk of cardiovascular diseases, type 2 diabetes mellitus, myeloid malignancies, and obesity. The shared pathogenetic mechanisms of obesity and CHIP contribute to the development of these conditions.

Summary: This article summarizes the current knowledge about clonal hematopoiesis of indeterminate potential (CHIP), its association with cardiovascular disease (CVD), and other outcomes, pathogenesis, postulated mechanisms of various pathologies, current knowledge gaps, possible targets of intervention, and therapeutic implications. Recently, CHIP has been identified as an independent risk factor for CVD and is associated with various other pathologies. CHIP is a clonal expansion of blood cells with leukemogenic mutations but without evidence of malignancy, and it is known to increase the inflammatory state and risk of CVD.

Summary: This study investigated the relationship between CHIP, LTL, and CAD using data from the Trans-Omics for Precision Medicine (TOPMed) program and UK Biobank. The results showed that genetically imputed longer LTL increased the risk of developing CHIP, which then hastened the shortening of measured LTL. There was also evidence of mediation between CHIP and CAD through LTL.

Summary: Cardiovascular disease is the leading cause of death in women, and women with history of adverse pregnancy outcomes (APOs) have a two-fold risk of future heart failure (HF). Hypertensive disorders of pregnancy (HDPs) and gestational diabetes mellitus (GDM) are associated with increased risk of HF, and further research is needed to understand underlying mechanisms and develop prevention strategies.

Summary: This study examined the associations and clinical utilities of various factors on coronary artery disease (CAD) recurrence, including genetic, sociodemographic, lifestyle, and clinical risk factors. The findings showed that current smoking and age at first CAD diagnosis were the most significant predictors of CAD recurrence. Other factors such as age at enrolment, CAD polygenic risk score, laboratory test results, and HDL cholesterol concentration were also significantly associated with recurrence risk.

Summary: Premature and early menopause are associated with increased risk of cardiovascular disease (CVD). This study found that early menopause is associated with specific biomarkers related to CVD and modifies the association between certain biomarkers and cardiovascular outcomes. The identified biomarkers reflect various biological pathways including inflammation, adiposity, and neurohormonal regulation.

Summary: This study found that clonal haematopoiesis of indeterminate potential (CHIP) is associated with incident arrhythmias, independent of other cardiovascular diseases such as coronary artery disease and heart failure, with the strongest associations observed for cardiac arrest. Gene-stratified analyses revealed an increased risk of arrhythmias across driver genes other than DNMT3A. CHIP may represent a novel risk factor for incident arrhythmias, indicating a potential target for modulation towards arrhythmia prevention and treatment.
