Carnosine, a natural dipeptide notably abundant in muscle tissue and recognized for its antioxidant attributes, may offer protective benefits against the deleterious effects of IR injury. <b>Methods:</b> A total of 24 rats were randomly allocated into four distinct groups: control, carnosine control, IR, and Carnosine + IR. The IR and Carnosine + IR groups underwent a simulated blood flow blockage lasting 120 min, followed by 120 min of reperfusion. Animals in the carnosine-treated groups received 250 mg/kg of carnosine via intraperitoneal injection prior to the experimental procedure. Muscle tissue samples were subsequently analyzed to quantify markers indicative of oxidative stress, inflammation, and cellular demise. <b>Results:</b> Our findings demonstrated that, when compared to control groups, the IR group exhibited a significant elevation in key markers of oxidative stress (total oxidant status [TOS], Oxidative Stress Index [OSI]), inflammation (myeloperoxidase [MPO]), and cell death (TUNEL, Necrosis, Edema). Specifically, the IR group presented with a TOS of 8.72 ± 0.97 μmol/L, an OSI of 2.03 ± 0.18, and an MPO level of 75.93 ± 5.72 U/L, contrasting with control values of 4.23 ± 0.56 μmol/L, 1.01 ± 0.13, and 43.26 ± 5.7 U/L, respectively. Histopathological assessments corroborated these findings, revealing severe necrosis (2.50 ± 0.55), edema (2.00 ± 0.63), and notable inflammatory cell infiltration (2.67 ± 0.52) within the IR group. Furthermore, apoptosis (quantified by TUNEL assay) was significantly increased to 18.83 ± 1.47% in the IR group. Carnosine administration in the Carnosine + IR group led to a substantial reduction in all these adverse markers, bringing their levels closer to those observed in the control groups. For instance, in the Carnosine + IR group, TOS decreased to 5.63 ± 0.87 μmol/L, OSI to 1.24 ± 0.25, and MPO to 55.91 ± 3.45 U/L. Similarly, histopathological scores for necrosis, edema, and inflammatory cell infiltration were markedly lower in the Carnosine + IR group. <b>Conclusion:</b> Our experimental findings strongly suggest that exogenously administered carnosine significantly reduces oxidative stress, suppresses inflammation, and attenuates cell death in skeletal muscle subjected to IR injury. These results highlight carnosine's promising therapeutic potential as a pharmacological agent for mitigating tissue damage in ischemic conditions.</p>","PeriodicalId":9494,"journal":{"name":"Cardiology Research and Practice","volume":"2025 ","pages":"2496873"},"PeriodicalIF":1.8,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12404830/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144991711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exercise-based cardiac rehabilitation (CR) is a cornerstone of post-MI treatment and management, yet its mechanistic effects on myocardial repair remain incompletely elucidated. This study aimed to the effect of exercise-based CR on the left ventricular dysfunction, mitophagy, and oxidative stress post-MI. <b>Methods:</b> Mendelian randomization analysis elucidated causal relationship between six physical activities and MI. Subsequently, 70 MI patients were randomized to control or exercise-based CR groups (moderate-to-vigorous physical activity intensity, 3 days/week, 10-50 min/day, 12 weeks); left ventricular function, cardiopulmonary function, and SF-36 quality of life scale were assessed pre-/postintervention using standardized protocols. Additionally, 21 rats were allocated to Sham, MI, or MI + treadmill running groups (high-intensity interval exercise training, 5 days/week, 30-50 min/day, 10-25 m/min, 4 weeks); left ventricular function, mitophagy, and oxidative stress were detected postintervention. <b>Results:</b> Genetically predicted moderate-to-vigorous intensity physical activity was significantly associated with lower risk of MI (IVW OR = 0.66, 95% CI: 0.54-0.81), with no causal links for other activities. Critically, clinical and animal studies demonstrated that exercise-based CR improved left ventricular systolic function (LVEF) after MI. Four-week exercise in MI rats enhanced mitophagy levels (LC3, FUNDC1, PINK1, and Parkin) and attenuated oxidative injury (MDA, GSH, SOD2, and GPX4) post-MI. Additionally, exercise-based CR also improved cardiopulmonary function (peak VO₂/kg, peakVO₂/pred%, and MET) in patients with MI and ameliorated mitochondrial damage in MI rats. However, GLS, secondary cardiopulmonary parameters (Wmax, HRR1min, peakVO₂/HR, and peakVO₂/HRpred%), and SF-36 (PCS and MCS) showed no significant changes, which may be associated with shorter duration of exercise intervention. <b>Conclusion:</b> Exercise-based CR significantly ameliorated left ventricular dysfunction, enhanced mitophagy levels, and attenuated oxidative stress post-MI, establishing its role in critical pathological mechanisms.
