Obesity and overweight conditions, frequently accompanied by hypercholesterolemia, are major risk factors for cardiovascular disease. Lifestyle interventions remain the cornerstone of non-pharmacological treatment; however, their effectiveness in improving lipid profiles is limited. Intermittent hypoxic training (IHT) has recently emerged as a potential strategy to enhance metabolic outcomes. This study aimed to evaluate the effects of a 4-week intensive IHT program combined with a calorie-restricted diet on lipid profile and body composition in men with overweight or obesity and secondary hypercholesterolemia. Twenty physically inactive men (35.3 ± 5.4 years) were randomly assigned to either a hypoxic group (H, n = 10) or a normoxic control group (C, n = 10). Both groups followed the same training protocol and diet, differing only in environmental training conditions. Body composition, resting metabolic rate, and blood lipid parameters (total cholesterol, TC; high-density lipoprotein cholesterol, HDL-C; low-density lipoprotein cholesterol, LDL-C; non-high-density lipoprotein cholesterol, non-HDL-C; Triglycerides, TG) were assessed before and after the intervention. Compared with the C group, participants in the H group achieved significantly greater reductions in body mass (−5.4% vs. −2.6%, p < 0.05) and fat mass (−14.7% vs. −7%, p < 0.01). IHT also induced marked decreases in TC (−22.6%, p < 0.001), LDL-C (−25.8%, p < 0.001), non-HDL-C (−26.5%, p < 0.001), and TG (−31.4%, p < 0.01), along with a significant improvement in the atherogenic index of plasma (AIP, −24.4%, p < 0.05). In contrast, the C group showed only non-significant downward trends. No significant changes in HDL-C were observed in either group. These findings suggest that IHT combined with dietary restriction produces more favorable changes in lipid profile and body composition than normoxic training. IHT may therefore represent a promising adjunct to conventional lifestyle-based interventions in the management of obesity-related hypercholesterolemia. Full article

Background/Objectives: Dyslipidemia is a global health concern. It refers to increased blood levels of LDL-C, triglycerides, and total cholesterol, accompanied by decreased blood HDL-C levels. Many pharmacological and non-pharmacological approaches have been designed to improve dyslipidemia management. However, nutritional therapies have gained more attention due to their antioxidant and anti-inflammatory properties. In this scenario, the carotenoid crocin stands out as a prominent anti-dyslipidemia phytochemical. Its unique structure permits lipid-lowering effects via various mechanisms, including the enhancement of lipid breakdown, reduction in lipid formation, bolstering of antioxidant defenses to diminish lipid toxicity, and decreased absorption of dietary fats. However, no recent systematic review or meta-analysis has addressed its anti-dyslipidemia effects with statistical power. Therefore, we aim to fill this gap with our current meta-analysis, as well as dose and time–response assessments. Methods: PubMed, SpringerLink, ScienceDirect, Cochrane, and Google Scholar databases were searched, and PRISMA guidelines were followed. Ten studies comprising eleven results were included. Results: Crocin did not improve LDL-C (0.2120, 95% CI: −0.0799 to 0.5040), HDL-C (−0.1937, 95% CI: −0.4896 to 0.1022), triglyceride (−0.2063, 95% CI: −0.5764 to 0.1638), or total cholesterol (0.1528, 95% CI: −0.1074 to 0.4129). The dose–response or time–response was also not statistically significant. Conclusions: More clinical studies with robust designs must be conducted to thoroughly assess crocin’s effectiveness in modulating lipid levels with the utmost care. Full article

This study investigated the effects of eight weeks of aerobic exercise training on body composition, lipid profiles, organokines (leptin, irisin), inflammatory biomarkers (high-sensitivity C-reactive protein [hs-CRP], interleukin-6 [IL-6]), and intestinal barrier permeability markers (zonulin, lipopolysaccharide-binding protein [LBP]) in overweight and obese women of different age groups. We hypothesized that aerobic exercise would improve cardiorespiratory fitness, body composition, lipid metabolism, and reduce pro-inflammatory responses and intestinal permeability, and that these effects would differ between age groups. A total of 32 participants with a body mass index (BMI) ≥ 23 kg/m² were randomly assigned to one of four groups (n = 8 per group): young exercise (YE), young control (YC), middle-aged exercise (ME), and middle-aged control (MC). The intervention consisted of treadmill running for 50 min per session, four times per week, at an intensity corresponding to 65% of the target heart rate (THR), calculated using the Karvonen formula, for a duration of eight weeks. Body composition variables included body weight, BMI, body fat mass (BFM), percentage body fat (PBF), lean body mass (LBM), and maximal oxygen uptake (VO₂max). Blood samples were analyzed for lipid profiles (total cholesterol [TC], triglycerides [TG], low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C]), organokines, inflammatory markers, and intestinal barrier integrity biomarkers. After the intervention, the YE and ME groups exhibited significant reductions (p < 0.05) in body weight, BMI, BFM, PBF, TC, TG, LDL-C, leptin, hs-CRP, IL-6, zonulin, and LBP. In contrast, LBM and VO₂max significantly increased (p < 0.05) in both exercise groups. No significant changes were observed in irisin concentrations or HDL-C levels (p > 0.05). These results suggest that aerobic exercise training, irrespective of age, is effective in improving cardiorespiratory fitness, body composition, and lipid metabolism, while simultaneously reducing systemic inflammation and is associated with favorable changes in circulating biomarkers of intestinal barrier function in overweight and obese women.

Background/Objectives: The effect of nutritional status on the prognosis of Familial Mediterranean Fever (FMF), a hereditary autoinflammatory illness, is unclear. This research aims to investigate whether nutritional status indicators, such as the Controlling Nutritional Status (CONUT) score and the Prognostic Nutritional Index (PNI), differ in kids with FMF compared to healthy kids. It also aims to investigate the possible relation between these indicators and the types of MEFV gene mutations detected in kids with FMF. Methods: The research included 90 kids with FMF and 90 healthy children as controls. The FMF group was further divided into three subgroups based on MEFV gene mutation status. The PNI and CONUT scores of these groups and subgroups were compared. Results: A difference was found in the distribution of CONUT scores in the FMF group compared to the healthy group. However, there was no difference in the distribution of PNI between the two groups. C-reactive protein, triglyceride, and total cholesterol values were higher in the FMF group than in the control group. A difference was also determined between the two groups in the distribution of total cholesterol scores categorized by CONUT score. A negative correlation was found between this categorized score and the number of symptom days. No significant difference was found in the distribution of PNI and CONUT scores among subgroups based on MEFV gene mutation status. Conclusions: In children with FMF, total cholesterol levels should be routinely monitored longitudinally, even if they remain within reference values, to prevent some complications in adulthood.

Adiponectin, an adipokine secreted by adipocytes with anti-inflammatory and insulin-sensitizing properties, circulates in several isoforms, of which total and high-molecular-weight (HMW) adiponectin are the most physiologically relevant. While adiponectin has been inversely associated with obesity and metabolic syndrome (MetS), evidence from Latin American populations remains scarce. To explore its role in this context, we conducted a case–control study in 310 Panamanian adults, including 77 individuals with MetS and 233 controls, diagnosed according to the Latin American Diabetes Association (ALAD) criteria. Serum adiponectin, lipid profile, glucose, HbA1c, and body composition were evaluated, with adiponectin quantified by chemiluminescent immunoassay (CLIA). Correlations with metabolic parameters were analyzed using GraphPad Prism 10.5. Participants with MetS exhibited significantly lower adiponectin concentrations compared with controls (7.75 ± 2.58 µg/mL vs. 9.53 ± 3.31 µg/mL, p = 0.0030). Adiponectin levels were significantly lower in males than in females (p = 0.0083) and showed inverse correlations with visceral fat (r = −0.26, p < 0.001), triglycerides (r = −0.25, p = 0.0062), insulin (r = −0.31, p < 0.0001), and HbA1c (r = −0.11, p = 0.046). Conversely, a positive association was observed with HDL cholesterol (r = 0.37, p < 0.0001). Individuals with HbA1c ≥ 6.5% or insulin ≥ 15 µU/mL exhibited markedly reduced adiponectin concentrations (p = 0.0006 and p < 0.0001, respectively). The ROC analysis yielded an AUC of 0.69, indicating a moderate discriminatory ability of adiponectin for identifying MetS in this population. These findings confirm that adiponectin is inversely associated with several metabolic risk factors, supporting its potential utility as a biomarker for early detection and risk stratification of metabolic syndrome in the Panamanian population.

Diabetes mellitus poses a global health challenge, necessitating natural adjuvants with minimal side effects. The aims of this study were to optimize the concentrations of chromium (Cr), zinc (Zn), and germanium (Ge) in the liquid fermentation media of Pleurotus citrinopileatus and Hericium erinaceus and to evaluate the hypoglycemic efficacy of buccal tablets in diabetic mice. The results showed that the optimal ion concentrations in the liquid fermentation medium were Cr 200 mg/L, Zn 200 mg/L, and Ge 50 mg/L for P. citrinopileatus, and Cr 200 mg/L, Zn 100 mg/L, and Ge 100 mg/L for H. erinaceus. After 3 weeks of administration of high-dose (6 g/kg) P. citrinopileatus and H. erinaceus buccal tablets, a 29.1% reduction in the blood glucose levels of diabetic mice was observed compared with pre-administration. High-dose tablets decreased the levels of total cholesterol, triglyceride, and low-density lipoprotein cholesterol while increasing high-density lipoprotein cholesterol. Compared with negative control, high-dose tablets increased catalase and superoxide dismutase activities by 31.2% and 34.1%, respectively. Moreover, the buccal tablets modulated the diversity and structure of the gut microbiota in mice. Relative abundance of beneficial genera (Lactobacillus, Akkermansia, Bifidobacterium, and Ruminococcus) in the high-dose group were increased, while diabetogenic taxa (Prevotella, Desulfovibrio, and Enterococcus) were inhibited. It is concluded that buccal tablets combining P. citrinopileatus and H. erinaceus treated with Cr, Zn, and Ge significantly ameliorated hyperglycemia, dyslipidemia, and oxidative stress, and reshaped the gut microbiota in diabetic mice, demonstrating the potential of edible mushrooms and trace elements as a natural antidiabetic therapy.

Background/Objectives: The clinical presentation of homozygous familial hypercholesterolemia (HoFH) and severe heterozygous familial hypercholesterolemia (sHeFH) often demonstrates substantial overlap, as low-density lipoprotein cholesterol (LDL-C) levels may fall within similar ranges in both conditions. Methods: In this single-center 10-year retrospective study at the University of Debrecen, Hungary, we present the clinical characteristics of patients with 6 HoFH and 6 sHeFH diagnosed by genetic testing, discuss the diagnostic limitations encountered in clinical practice, and outline the key components of therapeutic management. Results: The mean age at diagnosis was lower in the HoFH group (31.83 ± 19.5 vs. 41.83 ± 15.9 years). The differences in total cholesterol (13.48 ± 7.4 vs. 11.02 ± 3.5 mmol/L) and LDL-C levels (10.89 ± 6.6 vs. 8.58 ± 3.26 mmol/L) between the groups were not statistically significant. Interestingly, vascular complications were more frequent in sHeFH group as well (4 vs. 1 patients). In neither the HoFH nor the sHeFH group were we able to achieve the target LDL-C levels, due in part to the specific features of the reimbursement system, patient and parental preferences, the extremely high baseline LDL-C levels, and certain genetic characteristics. Conclusions: Our findings highlight the importance of genetic testing-based personalized therapy in these specific patient subpopulations. We emphasize that serum LDL-C alone is insufficient to distinguish between HoFH and sHeFH patients, and that therapeutic challenges should be anticipated in both groups arising partly from limited patient adherence as well as from financial constraints.

Objective: This study aimed to examine the associations between malnutrition and circulating blood markers in older adults. Methods: We conducted a prospective cohort study on octogenarians residing in the mountain community of the Sirente geographic area in Central Italy. Data collection was conducted from December 2023 to September 2024. Malnutrition was defined based on the Global Leadership Initiative on Malnutrition (GLIM) criteria. A panel of blood markers was examined, and principal component analysis (PCA) was used to identify clusters of related molecules. Both unadjusted and adjusted binary logistic regression models were applied to investigate the associations between malnutrition and these molecular clusters. Results: Data from 196 older adults (mean age: 86.2 years) were analyzed. Malnutrition was positively associated with PC 2 (i.e., urea, c-terminal agrin fragment, and potassium) (odds ratio [OR] = 1.647, p-value: 0.039) and negatively associated with PC 3 (i.e., hemoglobin, hematocrit, and red blood cell count) (OR = 0.567, p-value: 0.022) and PC 4 (i.e., calcium, albumin, total protein levels, and HDL cholesterol) (OR = 0.607, p-value: 0.035). Conclusions: Findings of the present study suggest that different clusters of blood markers are associated with malnutrition in older adults. Specifically, malnutrition is associated with clusters related to kidney function, anemia, neuromuscular function, and nutrient availability. These associations likely reflect the underlying biological mechanisms contributing to the development of malnutrition in this population. Full article

Introduction: Polycystic ovary syndrome (PCOS) is associated with obesity, numerous metabolic complications, and an increased risk of cardiovascular disease. Adipokines, secreted by adipose tissue, may contribute to the development of these cardiometabolic disturbances. The aim of this study was to investigate the adipokine levels and their relationship with metabolic status in adolescent girls with PCOS. Patients and Methods: This cross-sectional study included 66 adolescent girls with PCOS (mean age: 16.5 ± 1.08 years; study group, SG) and 30 regularly menstruating girls (mean age: 16.2 ± 1.37 years; control group, CG) recruited between 2012 and 2017. All participants underwent physical examination, body composition assessment, liver ultrasonography, and biochemical and hormonal evaluations. Fasting venous blood samples were collected to determine the adipokine profile, and the leptin-to-adiponectin ratio (L/A) was calculated. Results: Compared with the control group, the PCOS group demonstrated significantly lower adiponectin (p = 0.019) and vaspin (p = 0.037) concentrations, and higher RBP-4 levels (p = 0.048). Positive correlations were observed between adiponectin, apelin, and omentin, while negative correlations were found between leptin and L/A and HDL cholesterol levels in the SG. Omentin showed a negative association, and leptin and L/A a positive association, with triglyceride concentration. In the SG, resistin and visfatin levels were negatively correlated with total cholesterol, and resistin also showed a negative correlation with LDL cholesterol. In patients with PCOS, adverse associations were observed between carbohydrate metabolism parameters and insulin resistance indices, while insulin sensitivity indices correlated positively with adiponectin and omentin concentrations. Visfatin levels in the SG correlated negatively with QUICKI. Conclusions: The adipokine profile of adolescent girls with PCOS differs from that of regularly menstruating peers, particularly in adiponectin, RBP-4, and vaspin concentrations. However, the absence of significant correlations between RBP-4 and vaspin and lipid or carbohydrate metabolism parameters suggests that these adipokines are not reliable markers of metabolic disturbances in adolescent girls with PCOS.

Astaxanthin has attracted considerable interest, owing to its potent antioxidant and pigmentation properties. To investigate its effects of astaxanthin on body color variation in Lutjanus erythropterus, fish were divided into a control group and a treatment group fed an astaxanthin-supplemented diet. Body color parameters, growth performance, and liver antioxidant enzyme activities were measured at the end of the experiment. Tissues, including skin, intestine, liver, and blood, were subsequently collected for transcriptome sequencing. The results demonstrate that the astaxanthin-treatment group exhibited significantly enhanced body coloration alongside improved body length, body weight, and specific growth rate compared to the control group (p < 0.05). Specifically regarding the red–green value (a*), the treatment group showed significantly higher values on the ventral skin, dorsal skin, and gill cover (p < 0.05). The yellow–blue (b*) and lightness (L*) values were also significantly elevated in the ventral skin and gill cover (p < 0.05), although no significant differences were observed in the dorsal skin (p > 0.05). The skin was identified as the tissue with the highest total carotenoid content. Astaxanthin supplementation enhanced liver antioxidant capacity, evidenced by significantly elevated total superoxide dismutase (T-SOD) activity and significantly reduced malondialdehyde (MDA) levels in the treatment group (p < 0.05). Catalase (CAT) activity did not differ significantly between groups (p > 0.05). Transcriptomic analysis identified several coloration-associated genes, such as bco1, bco2, gstt1, and gstz1. It also revealed significant enrichment in key metabolic pathways (fatty acid, cholesterol, and retinol metabolism) and signaling pathways (PPAR and PI3K-Akt). Furthermore, the expression of multiple solute-carrier family members and apolipoproteins was detected, with notable enrichment in lipid digestion and absorption, cholesterol metabolism, and several key immune-related signaling pathways. These findings provide a theoretical basis for understanding the molecular mechanisms of carotenoid-mediated pigmentation in L. erythropterus. Full article

This study investigated the effects of vitamin E supplementation on growth performance, antioxidant capacity, and hepatic lipid metabolism in one-year-old juvenile Chinese sturgeon (Acipenser sinensis). A total of 270 fish (initial weight 1.37 ± 0.04 kg) were allocated into 9 fiberglass tanks and fed isonitrogenous and isolipidic diets with graded concentrations of vitamin E (DL-α-tocopherol acetate) including, 0, 1000, and 2000 mg/kg, respectively, for 2 months. Results showed that 1000 mg/kg vitamin E significantly improved growth performance and decreased hepatosomatic index. Dietary vitamin E supplementation significantly reduced the hepatic crude protein and crude lipid levels, withnot significantly affecting moisture and crude ash. Dietary vitamin E led to significant increases in plasma high-density lipoprotein cholesterol and vitamin E levels, while decreasing plasma low-density lipoprotein cholesterol. Additionally, it raised liver vitamin E content and reduced hepatic triglycerides, total cholesterol, crude protein, and crude lipid levels. Vitamin E also significantly downregulated mRNA levels of lipogenesis-related genes (ACC1, acetyl-CoA carboxylase 1; FASN, fatty acid synthase; and PPARγ, peroxisome proliferator activated receptor γ) and inhibited the enzyme activities of ACC1 and FASN, while upregulating lipolysis-related genes (HSL, hormone-sensitive lipase; CPT1, carnitine palmitoyltransferase 1α, and PPARα, peroxisome proliferator activated receptor α) and enhancing the activities of HSL and CPT1α. Furthermore, vitamin E supplementation significantly improved plasma reduced glutathione and superoxide dismutase activities, lowered plasma reactive oxygen species, malondialdehyde levels, and hepatic malondialdehyde contents, and upregulated mRNA levels of hepatic Nrf2 (nuclear factor-erythroid 2 related factor 2), Keap1 (Kelch-like epichlorohydrin associating protein 1), and CuZnSOD (copper/zinc superoxide dismutase). In conclusion, dietary 1000 mg/kg vitamin E supplementation could improve growth performance, enhance antioxidant capacity, and reduce liver fat deposition, indicating its potential as a beneficial dietary additive for promoting health and lipid regulation in juvenile Chinese sturgeon.

Background/Objectives: Non-high-density lipoprotein (non-HDL) cholesterol provides a practical alternative for assessing dyslipidemia, with the advantage of not requiring fasting. The aim of this study was to evaluate the utility of non-HDL cholesterol measured in random (non-fasting) samples for screening dyslipidemia in children and adolescents with overweight or obesity. Methods: We retrospectively analyzed 751 children and adolescents (268 boys and 483 girls) aged 2 to 19 years with overweight or obesity. They underwent lipid profile evaluation without fasting. Dyslipidemia was defined as the presence of one or more of the following: total cholesterol ≥ 200 mg/dL, triglycerides ≥ 100 mg/dL (ages 0–9) or ≥130 mg/dL (ages 10–19), low-density lipoprotein (LDL) cholesterol ≥ 130 mg/dL, and HDL cholesterol < 40 mg/dL. A cutoff value of ≥145 mg/dL was used for non-HDL cholesterol. The sensitivity and specificity of non-HDL cholesterol were compared with those of fasting-state data from the Korean National Health and Nutrition Examination Survey. Results: Dyslipidemia was identified in 52.6% of children and adolescents with overweight or obesity. Non-HDL cholesterol ≥ 145 mg/dL was observed in 18.7% of boys and 17.0% of girls, and dyslipidemia was observed in 94.0% and 85.4% of boys and girls with high non-HDL cholesterol, respectively. Non-HDL cholesterol demonstrated excellent performance in detecting elevated measured LDL cholesterol, with a sensitivity and specificity of 100% and 92.0%, respectively, for boys and 97.8% and 91.3%, respectively, for girls. When stratified by age, non-HDL cholesterol showed sensitivity comparable to or higher than that of total cholesterol for both boys and girls. The sensitivity of non-HDL cholesterol in random samples was significantly higher than that of non-HDL cholesterol in fasting-state samples from boys (100% vs. 94.3%, p = 0.010), with a similar trend shown by girls (92.9% vs. 92.3%, p = 0.510). Conclusions: Non-HDL cholesterol measurement may be a reliable and practical tool for dyslipidemia screening in children and adolescents with overweight or obesity. Its applicability in non-fasting conditions makes it a convenient tool for routine clinical use. Full article

Background: Coronary artery bypass grafting (CABG) remains a standard revascularization strategy for patients with advanced coronary artery disease (CAD). However, a considerable proportion of patients experience recurrent ischemia requiring repeat revascularization. Residual platelet reactivity (RPR) and dyslipidemia are recognized as key factors contributing to graft failure and disease progression. Methods: This observational study was conducted at a tertiary cardiology center in Kazakhstan. A total of 195 post-CABG patients who underwent repeat coronary angiography between 2023 and 2024 recruitment period for recurrent ischemic symptoms within 6–36 months after surgery were included. Clinical characteristics, comorbidities, lipid profiles, and antiplatelet response were analyzed. RPR was measured using the VerifyNow P2Y12 assay when available. Dyslipidemia was defined according to the 2019 and 2021 European guidelines. Results: Elevated RPR was identified in 45% of patients (n = 90) despite dual antiplatelet therapy (p < 0.01). Poor lipid control was frequent among those who underwent repeat percutaneous coronary intervention (PCI), particularly elevated levels of low-density lipoprotein cholesterol (LDL-C) and total cholesterol (p < 0.05). Both elevated RPR and dyslipidemia were independently associated with native coronary disease progression and graft failure (RPR: OR = 2.8; 95% CI 1.4–5.6; p = 0.003; dyslipidemia: OR = 2.2; 95% CI 1.1–4.3; p = 0.02). The use of ezetimibe was independently associated with a significantly lower risk of repeat stenting (OR = 0.12; 95% CI 0.02–0.75; p = 0.023). Smokers were younger, had lower blood pressure, and less frequently presented with diabetes or chronic kidney disease, demonstrating a pattern consistent with the “smoker’s paradox.” Conclusions: Residual platelet reactivity and dyslipidemia are common and clinically relevant predictors of repeat revascularization after CABG. Optimization of antiplatelet and lipid-lowering therapy should be prioritized in secondary prevention for this high-risk population. These findings are particularly important in Kazakhstan, where post-CABG management strategies warrant further improvement. Full article

Akkermansia muciniphila—a mucus-resident commensal—has emerged as a promising target at the interface of metabolism, barrier function, and immunity. Observational human studies link higher intestinal abundance of A. muciniphila with healthier adiposity and glycemic profiles, while preclinical experiments demonstrate causal benefits on adiposity, insulin resistance, gut-barrier integrity, and inflammatory tone. These effects are attributed to mucus-layer reinforcement, reduced intestinal permeability and endotoxemia, production of short-chain fatty acids, and host signaling by defined bacterial components. In a randomized proof-of-concept trial in overweight/obese insulin-resistant adults, pasteurized A. muciniphila was safe and well-tolerated and improved insulin sensitivity and total cholesterol versus placebo; live cells showed directionally favorable but non-significant trends. A separate multicenter randomized trial of a five-strain consortium that included A. muciniphila improved post-prandial glucose and HbA1c in type 2 diabetes, supporting translational potential while underscoring the need for strain-resolved studies. Evidence for liver and cardiovascular benefits is strong in animals (e.g., MASLD and atherosclerosis models) but remains preliminary in humans. Inter-individual response heterogeneity—potentially influenced by baseline Akkermansia levels and gut-barrier status—highlights the value of personalized, microbiome-guided approaches. Larger, longer clinical studies are now warranted to define optimal dosing and formulation (live vs. pasteurized), durability, safety across populations, and impacts on hard outcomes (clinically meaningful weight change, glycemic endpoints, and cardiometabolic events). Overall, A. muciniphila represents a promising microbial adjunct for metabolic health with a plausible path from postbiotic concepts to clinical application, pending confirmatory trials.

Background: A decreased level of adiponectin is known as a predictor of adverse left ventricular remodeling and major adverse cardiac events (MACEs). We evaluated long-term MACEs following ST-segment elevation myocardial infarction (STEMI) in relation to adiponectin levels. Methods: This prospective study included a total of 73 consecutive STEMI patients. Adiponectin, CK, CK-MB, cTnI, CRP, HDL cholesterol, LDL cholesterol, triglycerides, and other routine laboratory parameters were considered, and myocardial revascularization and two-dimensional echocardiography were performed. Subjects were divided into two groups according to their serum adiponectin concentrations. Results: In total, 24 (32.87%) patients suffered from MACEs, 19 (26.02%) with adiponectin value ≤ 1.8 ng/mL (group 1) and 5 (6.84%) with adiponectin value > 1.8 ng/mL (group 2) (p < 0.013). Heart failure (Killip >1) was present in 14 cases (19.17%) in group 1 and in 3 cases (4.1%) in group 2 (p < 0.001). Kaplan–Meier analysis was used to depict the occurrence of MACEs according to the adiponectin threshold identified during hospitalization (1.8 ng/mL). The log-rank test revealed a statistically significant difference in survival between groups (p = 0.013), and the AUC value for adiponectin was 0.77 (95% CI, 0.66–0.89), p = 0.01. Based on univariate logistic regression analysis, adiponectin and BMI were significantly associated with MACEs (p = 0.018, p = 0.034). Multivariate logistic regression analysis shows that serum adiponectin predicts MACEs after STEMI (p = 0.011). Conclusions: We found significant associations between adiponectin levels and MACEs in patients who survived STEMI. The established cut-off value of 1.8 ng/mL for adiponectin during hospitalization identified patients at risk for MACEs. Full article
