Purpose: The constitutive elements of the metabolic syndrome (MetS) are linked with both non-alcoholic fatty liver disease (NAFLD) and cardiovascular disease. Controlled attenuation parameter (CAP), and vibration controlled transient elastography (VCTE), are able to detect and quantify NAFLD, while conventional and two-dimensional speckle tracking echocardiography (2D-STE) is capable to identify subclinical changes in cardiac function. We wanted to evaluate whether there is any correspondence between left ventricular (LV) diastolic dysfunction and different degrees of liver steatosis and fibrosis in MetS subjects with NAFLD. Patients and Methods: A total of 150 adult subjects having MetS and a normal left ventricular (LV) systolic function were recorded in the study, while 150 age- and sex- matched adults without MetS were enrolled as controls. NAFLD was established by VCTE and CAP. The left heart systolic and diastolic function was evaluated by conventional and 2D-ST echocardiography. Left atrial (LA) stiffness was calculated as the ratio between the E/A ratio and the LA reservoir-strain. Results: In univariate regression analysis, the variables associated with LV diastolic dysfunction in MetS patients were: liver steatosis grade ≥ 2, liver fibrosis grade ≥ 2, the longitudinal LA peak strain during the reservoir phase, the LA strain rate during ventricular contraction and the LA stiffness. In multivariate logistic regression, two variables were selected as independent predictors of LV diastolic dysfunction, namely the liver stiffness (P=0.0003) and the LA stiffness (P< 0.0001). LA stiffness predicted subclinical LV diastolic dysfunction in MetS patients with a sensitivity of 45% and a specificity of 96% when using a cut-off value > 0.38, and was significantly correlated with liver steatosis stage ≥ 2 and liver fibrosis stage ≥ 2. Conclusion: The present study confirms the association between liver stiffness, LA stiffness and LV diastolic dysfunction in MetS patients. Our study suggests that liver elastography and 2D-STE should become habitual assessments in MetS patients.

Background: Sex-related differences in left ventricular (LV) reverse remodeling following ST-segment elevation myocardial infarction (STEMI) remain underexplored. We aimed to investigate predictors of reverse remodeling and its association with clinical outcomes, with a focus on sex-specific differences. Methods: We enrolled 253 STEMI patients (91 women, 28%) and assessed echocardiographic parameters at baseline and six months. LV reverse remodeling was defined as a ≥15% reduction in LV end-diastolic volume (LVEDV). Multivariate logistic regression identified independent predictors of remodeling. Clinical outcomes were evaluated over a median follow-up of 17 months (IQR 14–22 months), including major adverse cardiac events (MACEs). Kaplan–Meier and Cox regression analyses were performed. Results: Reverse remodeling occurred in 43% of patients and was more frequent in men than women (47% vs. 37%, p = 0.04). Male sex (OR 0.30; 95% CI: 0.14–0.65; p < 0.0001) and baseline global work efficiency (GWE) (OR 1.64; 95% CI: 1.45–1.85; p < 0.0001) were independent predictors. Men exhibited greater reductions in LVEDV, greater improvements in LV ejection fraction, and superior myocardial work indices. Over the follow-up, patients with reverse remodeling had significantly lower MACE rates compared to those without (10% vs. 24%, p < 0.01). Cox regression demonstrated that reverse remodeling was associated with a reduced risk of MACEs (HR 0.318; 95% CI: 0.181–0.557; p < 0.0001). Conclusions: LV reverse remodeling after STEMI is associated with improved clinical outcomes and is influenced by sex-specific differences. Baseline myocardial work indices, particularly GWE, are strong predictors of reverse remodeling. Men demonstrated a more favorable remodeling profile and myocardial recovery compared to women.

Hypoglycemic medications are widely used in managing diabetes mellitus, with emerging evidence suggesting their role in cardiac reverse remodeling. This systematic review aims to quantitatively synthesize data regarding the impact of these medications on left ventricular end-diastolic diameter (LVEDD) and end-systolic diameter (LVESD), and to evaluate the clinical relevance of these changes in promoting favorable cardiac outcomes. We conducted a comprehensive search across PubMed, Scopus, and the Web of Science up to 22 April 2024, selecting studies based on inclusion criteria that focused on the impact of hypoglycemic medications on LVEDD and LVESD in patients with diabetes. Studies were selected through a rigorous process, adhering to PRISMA guidelines, and involving various designs including randomized controlled trials and observational studies. The main outcomes were changes in LVEDD and LVESD measured by validated cardiac imaging techniques. A total of ten studies met the inclusion criteria, involving a total of 1180 patients. Treatment durations ranged from 3 to 24 months. Significant improvements in cardiac dimensions were noted with some medications. For instance, Liraglutide treatment over three months significantly improved LVEF from 47.2% to 57.2% and reduced LVEDD and LVESD from 46.5 mm to 45.2 mm and 35.2 mm to 32.7 mm, respectively. In contrast, other medications like Sitagliptin showed minimal impact over 24 months. On average, hypoglycemic medications reduced LVEDD from 58.2 mm to 55.0 mm and LVESD from 48.3 mm to 44.3 mm, with a mean improvement in LVEF from 38.9% to 43.8%. Hypoglycemic medications contribute variably to cardiac reverse remodeling. Medications such as Liraglutide and Dapagliflozin demonstrate significant potential in improving cardiac dimensions and function, indicating their utility beyond glycemic control. This review highlights the need for tailored treatment approaches to maximize cardiac outcomes in patients with diabetes, suggesting a broader therapeutic role for these agents.

Lipoprotein(a) [Lp(a)] is a highly heritable apoB-containing lipoprotein and a causal contributor to atherosclerotic cardiovascular disease that may contribute to residual cardiovascular risk after myocardial infarction (MI), while the clinical benefit of selective pharmacological Lp(a) lowering remains unresolved. This narrative review examines Lp(a) as a determinant of residual and recurrent cardiovascular risk after MI, integrating molecular biology, human genetics, coronary imaging, post-MI observational studies, measurement considerations, current management, and emerging therapies. Elevated Lp(a) has been associated with coronary plaque progression, high-risk plaque features, oxidized-phospholipid-related inflammatory pathways, recurrent ischemic events, and repeat revascularization, although prognostic associations vary across populations and endpoints. Because concentrations measured during acute MI may underestimate the stable Lp(a) phenotype in some patients, selective repeat measurement after clinical stabilization may be appropriate when classification could influence management or trial eligibility. Contemporary treatment remains centered on intensive control of LDL-C and other modifiable risk factors, while antisense oligonucleotides, small interfering RNAs, and oral particle-assembly inhibitors can produce profound Lp(a) reductions. According to sponsor-reported topline data released in September 2026, pelacarsen lowered Lp(a) but did not significantly reduce the prespecified primary cardiovascular endpoint in the overall Lp(a)HORIZON population; complete peer-reviewed results are not yet available. The sponsor-reported neutral HORIZON topline result raises unresolved questions regarding baseline Lp(a) and absolute reduction, timing of intervention and disease stage, and endpoint composition. Full peer-reviewed HORIZON data and ongoing cardiovascular outcome trials will be required to determine whether and under what conditions selective Lp(a) lowering translates into cardiovascular benefit.

Background/Objectives: Heart failure with preserved ejection fraction (HFpEF) is increasingly recognized as a systemic inflammatory syndrome with limited diagnostic and prognostic tools applicable in routine practice. Hematological indices derived from complete blood count, including neutrophil-to-lymphocyte ratio (NLR), red cell distribution width (RDW), and platelet-to-lymphocyte ratio (PLR), have emerged as potential markers of systemic inflammation and cardiovascular risk. This study aimed to compare these indices between patients with HFpEF and individuals without heart failure and to examine their associations with disease severity and 12-month clinical outcomes. Methods: In this retrospective observational study, 221 patients with confirmed HFpEF were compared with 143 control subjects without heart failure. NLR, RDW, and PLR were calculated from routine laboratory tests. Associations with echocardiographic parameters, NT-proBNP levels, and clinical outcomes were analyzed. Patients were followed for 12 months to assess major adverse cardiovascular events (MACEs), all-cause mortality, and heart failure-related rehospitalization. Multivariable Cox regression models were used to evaluate independent prognostic value. Results: Patients with HFpEF exhibited significantly higher NLR (3.98 ± 0.98 vs. 2.72 ± 0.81), RDW (14.62 ± 1.09% vs. 13.48 ± 0.92%), and PLR (152.4 ± 38.7 vs. 131.9 ± 29.6) compared with controls (all p < 0.001). NLR and RDW correlated with NT-proBNP, E/e′ ratio, left atrial volume index, and NYHA class. Higher tertiles of NLR and RDW were associated with progressively increased rates of MACEs and all-cause mortality, with statistically significant trends across tertiles (all p-trend ≤ 0.008). In multivariable analysis, NLR (HR 1.28, p = 0.001) and RDW (HR 1.32, p < 0.001) remained independently associated with 12-month MACEs, while PLR showed borderline significance. However, ROC analysis demonstrated limited discrimination, with AUC values ranging from approximately 0.55 to 0.61, indicating that none of the three indices reliably discriminated between patients with and without MACEs when considered individually. Conclusions: NLR and RDW were elevated in patients with HFpEF and were independently associated with disease severity and 12-month MACEs. However, all three indices showed limited individual discrimination and should not be considered standalone prognostic tools. Their potential clinical value, if any, requires evaluation as part of validated multivariable prediction models.

Background: Patients with type 2 diabetes mellitus (T2DM) who present with ST-segment elevation myocardial infarction (STEMI) remain at high risk of adverse remodeling after reperfusion. This observational study examined whether pre-admission glucose-lowering therapy class was associated with six-month left ventricular (LV) reverse remodeling and myocardial work recovery. Methods: We analyzed 253 patients with STEMI, baseline LV ejection fraction ≤ 50%, successful primary PCI, and complete baseline and six-month echocardiography. The primary inferential analyses focused on 75 patients with T2DM, grouped according to pre-admission therapy with SGLT-2 inhibitors, GLP-1 receptor agonists, DPP-4 inhibitors, or conventional therapy; non-diabetic patients were retained as a descriptive reference group. Clinical outcome, propensity-score, subgroup, and mediation analyses were considered exploratory because of small subgroup and event counts. Results: SGLT-2 inhibitor and GLP-1 receptor agonist exposure was associated with larger improvements in LVEF, LV volumes, and global work efficiency than DPP-4 inhibitors or conventional therapy. Crude MACE rates were highest in the conventional-therapy group, but event estimates were imprecise and confounded by baseline risk, revascularization status, and discharge therapy. Conclusions: In patients with T2DM recovering from STEMI, pre-admission exposure to SGLT-2 inhibitors and, to a lesser extent, GLP-1 receptor agonists was associated with more favorable structural and myocardial work recovery. These hypothesis-generating findings should be interpreted as associations and require confirmation in adequately powered prospective studies.
