Special Issue Information

Dear Colleagues,

Cardiovascular disease is still the leading cause of morbidity and mortality worldwide despite the great diagnostic and therapeutic progress made in recent decades. Intervention using cardiovascular risk factors is seen as the best long-term solution to improve the outcome of these patients. Therefore, their identification and appropriate therapeutic approach are of the utmost importance.

Some of them are behavioral risk factors, such as unhealthy diet, physical inactivity, tobacco use, and excessive alcohol consumption. Although it is not difficult to correct them, their prevalence remains high because the population is not fully aware of their harmful effect on health. The continuous and long-term action of behavioral risk factors is associated with overweight and obesity, atherogenic dyslipidemia, diabetes, and hypertension, all of which are strong risk factors for cardiovascular disease. The risk of stroke, ischemic heart disease, peripheral artery disease, heart failure, and death that an individual has increases exponentially as risk factors accumulate because they potentiate each other and accelerate target organ damage.

Although there are many different risk factors that increase the likelihood of developing cardiovascular disease, they are largely preventable. By implementing a healthy lifestyle and appropriate pharmacological intervention, we can improve the longevity and quality of life of millions of people around the world.

We invite you to share your knowledge and experience by contributing to this Special Issue. Original and review papers that address cardiovascular risk factors in all aspects, from cellular and molecular mechanisms, and pathophysiological links to problems of diagnosis, treatment, and monitoring, are welcome. We look forward to receiving your contributions.

Background/Objectives: Long-term hospitalization in cardiac patients is associated with significant metabolic and microbial alterations that may influence disease progression and prognosis. Although lipid imbalances, metabolomic shifts, and gut microbiome dysbiosis have each been linked individually to cardiovascular outcomes, their integrated evaluation in long-term-hospitalized patients remains underexplored. Methods: We conducted a retrospective observational study including 51 cardiac patients hospitalized for more than 25 days, compared with a control group of 41 patients hospitalized for short and intermediate durations (3–24 days). Clinical and demographic data were collected, alongside lipid profiling, metabolomic assessment through liquid chromatography–mass spectrometry (LC-MS), and gut microbiome analysis using GI360™ sequencing. Ethical approval was obtained, and all data were anonymized. Lipid-related findings are exploratory due to the small number of complete measurements. Results: Preliminary lipid trends were characterized by higher levels of LDL, triglycerides, and Lp(a), and lower HDL, in the long-term group. Metabolomic analyses revealed decreased energy-related metabolites (ATP, phosphocreatine ratio), altered amino acid patterns, and increased ketone utilization. Gut microbiome evaluation demonstrated a significant increase in dysbiosis index, with reduced diversity and dominance of potentially pathogenic taxa. These findings were correlated with clinical severity scores. Cross-domain relationships are exploratory and based on associative profiling rather than deep integrative modelling. Conclusions: Long-term hospitalization in cardiac patients is associated with distinct lipid, metabolomic, and gut microbiome profiles that may serve as predictive biomarkers of adverse outcomes. Future studies should validate these findings in larger cohorts and explore their integration into personalized management strategies. Full article

Background/Objectives: Although systematic reviews and meta-analyses have examined immune-inflammatory indices in cardiovascular disease (CVD), the evidence remains scattered and inconsistent. This umbrella review aims to synthesize findings and evaluate the overall predictive value of these indices for clinical outcomes. Methods: We systematically searched PubMed, Cochrane Library, Web of Science, Embase, Scopus, and Medline for systematic reviews with meta-analyses assessing neutrophil-to-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), platelet-to-lymphocyte ratio (PLR), and systemic inflammation response index (SIRI) in patients with CVD. Study quality and certainty of evidence were appraised using AMSTAR-2 and GRADE, respectively. Results: A total of 35 meta-analyses covering 106 unique outcomes were included, of which 87 showed significant associations. Elevated NLR and SII were consistently linked to higher risks of CVD mortality, major adverse cardiovascular events, myocardial infarction, heart failure, and stroke. PLR and SIRI were primarily associated with poor recovery from stroke and increased mortality in ST-elevation myocardial infarction. Specifically, the methodological quality of the included reviews was generally moderate to high according to AMSTAR-2, whereas none of the associations reached high certainty based on GRADE, with most rated as low or very low and about one-quarter as moderate certainty. Conclusions: The overall certainty of evidence remains limited according to GRADE, alongside methodological heterogeneity, population variability, and inconsistent thresholds that further restrict the direct applicability of these findings in clinical practice. Nevertheless, available evidence indicates that elevated immune-inflammatory indices are likely associated with worse clinical outcomes in patients with CVD. Future research should prioritize establishing standardized cutoffs, improving methodological consistency, and validating these indices across diverse populations to support their integration into clinical risk-stratification frameworks.
