Advances in medical treatment over recent decades have reduced mortality, yet morbidity remains high. Many patients now survive into adulthood but continue to have chronic heart disease and often develop complications such as heart failure, arrhythmias, pulmonary hypertension, and acquired cardiac and non-cardiac comorbidities, all of which require ongoing specialized care. Additionally, many adults with CHD (ACHD) lead a sedentary lifestyle, are overweight, and experience mental health issues, further affecting their well-being and quality of life. In this context, preventive, prehabilitative, and rehabilitative measures play an important role in reducing cardiovascular risks and enhancing overall quality of life. Preventive strategies aim to improve physical fitness, address health risks early, and support long-term well-being. Prehabilitation involves a structured, multimodal approach designed to strengthen physical and psychological resilience before planned medical interventions, thereby reducing complications and recovery times. Rehabilitation, on the other hand, facilitates recovery after treatment and promotes sustained health improvements over time. The German Pension Insurance provides programs aimed at enhancing physical fitness, promoting mental well-being, and improving quality of life, with a focus on maintaining employability and supporting occupational reintegration. However, available offerings are often not tailored to the specific needs of the heterogenous group of ACHD, limiting their potential effectiveness.

Further investigation into the role of ANXA7 in coronary atherosclerosis is crucial for elucidating its pathogenic mechanisms and exploring potential clinical applications.</p>","PeriodicalId":9592,"journal":{"name":"Cardiovascular diagnosis and therapy","volume":"15 3","pages":"653-664"},"PeriodicalIF":2.1,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12246990/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the accuracy of miRNA-29b in diagnosing acute myocardial infarction (AMI) and its association with postinfarction cardiac function.</p><p><strong>Methods: </strong>A total of 106 patients with AMI admitted to the Department of Cardiology of Hebei General Hospital between January 2023 and July 2024 were prospectively enrolled within 24 hours of symptom onset. Indicators including circulating miRNA-29b levels [detected via real-time quantitative polymerase chain reaction (RT-qPCR)], myocardial enzymes, vascular endothelial growth factor (VEGF), and tumor necrosis factor-α (TNF-α) were assessed at baseline. Cardiac function was assessed by echocardiography. Left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), left ventricular end-diastolic diameter (LVEDd), left ventricular end-systolic diameter (LVEDs), and left ventricular posterior wall thickness at end-diastole (LVPWd) and end-systole (LVPWs) were also measured. Based on echocardiography, patients with AMI (n=106) were divided into an abnormal cardiac function (ACF) group (LVEF <50%; n=50) or a normal cardiac function (NCF) group (LVEF ≥50%; n=56). Thirty healthy participants were selected as the control group. Variables were compared with independent samples t-tests. Correlation and receiver operating characteristic (ROC) curve analyses were also conducted.</p><p><strong>Results: </strong>There was no significant differences in baseline demographic or clinical characteristics between the AMI and control groups; however, the control group, compared with the AMI group, had lower levels of low-density lipoprotein cholesterol (2.72±0.58 <i>vs.</i> 3.53±0.77 mmol/L; P<0.001) and fasting blood glucose (7.00±1.61 <i>vs.</i> 8.77±2.37 mmol/L; P<0.001). Moreover, the relative blood miRNA-29b expression was significantly lower in the AMI group than in the control group (0.31±0.16 <i>vs.</i> 0.73±0.40; P<0.01), and the expression was lower in the ACF group than in the NCF group (0.24±0.15 <i>vs.</i> 0.39±0.14; P<0.01). Correlation analysis showed that miRNA-29b was positively correlated with LVEF [r=0.608; P<0.001; 95% confidence interval (CI): 0.494-0.701] and LVFS (r=0.583; P<0.001; 95% CI: 0.448-0.702). Conversely, it was negatively correlated with cardiac troponin T (cTnT) level (r=-0.687; P<0.001; 95% CI: -0.769 to -0.610), creatine kinase-MB (r=-0.626; P<0.001; 95% CI: -0.744 to -0.488), VEGF (r=-0.581; P<0.001, 95% CI: -0.708 to -0.422), TNF-α (r=-0.527; P<0.001; 95% CI: -0.658 to -0.369), LVEDd (r=-0.451; P<0.001; 95% CI: -0.578 to -0.284), and LVEDs (r=-0.462; P<0.001; 95% CI: -0.593 to -0.330).
