Review
Coronary artery disease (CAD) and hypertension significantly contribute to cardiovascular morbidity and mortality. MicroRNAs (miRNAs) have recently emerged as promising biomarkers and therapeutic targets for these conditions. This systematic review conducts a thorough analysis of the literature, with a specific focus on investigating miRNA expression patterns in patients with CAD and hypertension. This review encompasses an unspecified number of eligible studies that employed a variety of patient demographics and research methodologies, resulting in diverse miRNA expression profiles. This review highlights the complex involvement of miRNAs in CAD and hypertension and the potential for advances in diagnostic and therapeutic strategies. Future research endeavors are imperative to validate these findings and elucidate the precise roles of miRNAs in disease progression, offering promising avenues for innovative diagnostic tools and targeted interventions.

Meta-Analysis Review
(1) Background: Cardiovascular diseases (CVDs) are the leading cause of mortality worldwide. The aim of the study was to examine the existing published results of the association between elevated serum phosphate concentrations and cardiovascular mortality, along with the CVD incidence and subclinical coronary atherosclerosis, in primary prevention among non-selected samples of the general population. (2) Methods: A systematic review and meta-analysis were carried out using literature obtained from PubMed, SCOPUS, and the Web Of Science until March 2024 and following the PRISMA guidelines. Relevant information was extracted and presented. Random and fixed effects models were used to estimate the pooled odds ratio (OR) and hazard ratio (HR) with their 95% coefficient interval (CI), and I was used to assess heterogeneity. (3) Results: Twenty-five studies met our inclusion criteria and were included in the meta-analysis (11 cross-sectional and 14 cohort studies). For cardiovascular mortality, which included 7 cohort studies and 41,764 adults, the pooled HR was 1.44 (95% CIs 1.28, 1.61; I 0%) when the highest versus the reference level of serum phosphate concentrations were compared. For CVDs, which included 8 cohort studies and 61,723 adults, the pooled HR was 1.12 (95% CIs 0.99, 1.27; I 51%). For subclinical coronary atherosclerosis, which included 11 cross-sectional studies and 24,820 adults, the pooled OR was 1.44 (95% CIs 1.15, 1.79; I 88%). (4) Conclusions: The highest serum phosphate concentrations were positively associated with a 44% increased risk of cardiovascular mortality and subclinical coronary atherosclerosis.

Temporal Trends in the Outcomes of Percutaneous Coronary Intervention With Zotarolimus Eluting Stents Versus Everolimus Eluting Stents: A Meta-Analysis of Randomized Controlled Trials.
INTRODUCTION
Long-term follow-up results of various trials comparing Zotarolimus eluting stents (ZES) with Everolimus eluting stents (EES) have been published recently. Additionally, over the last decade, there have been new trials comparing the ZES with various commercially available EES. We aim to conduct an updated meta-analysis in light of new evidence from randomized controlled trials (RCTs) to provide comprehensive evidence regarding the temporal trends in the clinical outcomes.
METHODS
A comprehensive literature search was conducted across PubMed, Cochrane, and Embase. RCTs comparing ZES with EES for short (<2 years), intermediate (2-3 years), and long-term follow-ups (3-5 years) were included. Relative risk was used to pool the dichotomous outcomes using the random effects model employing the inverse variance method. All statistical analysis was conducted using Revman 5.4.
RESULTS
A total of 18 studies reporting data at different follow-ups for nine trials (n = 14319) were included. At short-term follow-up (<2 years), there were no significant differences between the two types of stents (all-cause death, cardiac death, Major adverse cardiovascular events (MACE), target vessel myocardial infarction, definite or probable stent thrombosis or safety outcomes (target vessel revascularization, target lesion revascularization, target vessel failure, target lesion failure). At intermediate follow-up (2-3 years), EES was superior to ZES for reducing target lesion revascularization (RR = 1.28, 95% CI = 1.05-1.58, p < 0.05). At long-term follow-up (3-5 years), there were no significant differences between the two groups for any of the pooled outcomes (p > 0.05).
CONCLUSION
ZES and EES have similar safety and efficacy at short, intermediate, and long-term follow-ups.

BACKGROUND
Stent restenosis is a relatively common phenomenon among patients with coronary heart disease undergoing percutaneous coronary intervention (PCI). It seems that a set of clinical, laboratory, and even genetic factors make people susceptible to such a phenomenon and in fact, this is multi-factorial. We aimed to first determine the underlying clinical and laboratory risk factors for the occurrence of stent re-stenosis after PCI based on a systematic review study, and after that, through a bioinformatics study, to evaluate the related genes and microRNAs with the occurrence of stent re-stenosis.
MAIN TEXT
In the first step, the manuscript databases including Medline, Web of Knowledge, Google Scholar, Scopus, and Cochrane were deeply searched by the two blinded investigators for all eligible studies based on the considered keywords to introduce clinical and laboratory determinants of stent re-stenosis. In the bioinformatic phase, and following a review of the literature to identify genes and microRNAs involved in restenosis, the interaction of each gene with other genes associated with stent re-stenosis was determined by GeneMANIA network analysis and Cytoscape software. Overall, 67 articles (including 40,789 patients) on clinical and biochemical predictors for stent restenosis and 25 articles on genetic determinants of this event were eligible for the final analysis. The predictors for this event were categorized into four subgroups patient-based parameters including traditional cardiovascular risk profiles, stent-based parameters including type and diametric characteristics of the stents used, coronary lesion-based parameters including several two target lesions and coronary involvement severity and laboratory-based parameters particularly related to activation of inflammatory processes. In the bioinformatic phase, we uncovered 42 genes that have been described to be involved in such a phenomenon considering a special position for genes encoding inflammatory cytokines. Also, 12 microRNAs have been pointed to be involved in targeting genes involved in stent re-stenosis.
CONCLUSIONS
The incidence of stent re-stenosis will be the result of a complex interaction of clinical risk factors, laboratory factors mostly related to the activation of inflammatory processes, and a complex network of gene-to-gene interactions.

Meta-Analysis
Red wine alleviates atherosclerosis-related inflammatory markers in healthy subjects rather than in high cardiovascular risk subjects: A systematic review and meta-analysis.
BACKGROUND
Moderate red wine (RW) consumption is associated with a low risk of cardiovascular disease (CVD). However, few studies have evaluated the effects of RW and white wine (WW) on inflammatory markers related to atherosclerosis in healthy individuals and high-risk subjects for CVD. This study aimed to assess the effect of RW on inflammatory markers in healthy individuals and high-risk subjects for CVD compared with moderate alcohol consumption.
METHODS
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 (PRISMA) was followed in this study. The PubMed, Embase, Cochrane, Web of Science, SinoMed, EbscoHost, and ScienceDirect databases were searched. The risk of bias and quality of the included trials were assessed using the Cochrane Handbook. The main results are summarized in Stata 12.
RESULTS
Twelve studies were included in the meta-analysis. The results demonstrated that RW significantly decreased circulating intercellular cell adhesion molecule-1, vascular cell adhesion molecule-1 (VCAM-1), tumor necrosis factor-alpha (TNF-α), lymphocyte function-associated antigen-1, and Sialyl-Lewis X expression on the surface of monocytes in healthy subjects, but not in patients with CVD. Additionally, RW significantly decreased Sialyl-Lewis X but increased clusters of differentiation 40 (CD40) expressed on the surface of T lymphocytes and significantly decreased C-C chemokine receptor type 2 (CCR2) and very late activation antigen 4 (VLA-4) expressed on the surface of monocytes. Interestingly, subgroup analysis also found that RW significantly decreased circulating interleukin-6 (IL-6) in Spain but not in other countries, and significantly increased αMβ2 (Mac-1) in the group that had an intervention duration of less than 3 weeks.
CONCLUSIONS
Moderate consumption of RW is more effective than WW in alleviating atherosclerosis-related inflammatory markers in healthy people rather than high-risk subjects for CVD, but this needs to be further confirmed by studies with larger sample sizes.

Meta-Analysis
Murray's law has been viewed as a fundamental law of physiology. Relating blood flow ([Formula: see text]) to vessel diameter () ([Formula: see text]·∝·), it dictates minimum lumen area (MLA) targets for coronary bifurcation percutaneous coronary intervention (PCI). The cubic exponent (3.0), however, has long been disputed, with alternative theoretical derivations, arguing this should be closer to 2.33 (7/3). The aim of this meta-analysis was to quantify the optimum flow-diameter exponent in human and mammalian coronary arteries. We conducted a systematic review and meta-analysis of all articles quantifying an optimum flow-diameter exponent for mammalian coronary arteries within the Cochrane library, PubMed Medline, Scopus, and Embase databases on 20 March 2023. A random-effects meta-analysis was used to determine a pooled flow-diameter exponent. Risk of bias was assessed with the National Institutes of Health (NIH) quality assessment tool, funnel plots, and Egger regression. From a total of 4,772 articles, 18 were suitable for meta-analysis. Studies included data from 1,070 unique coronary trees, taken from 372 humans and 112 animals. The pooled flow diameter exponent across both epicardial and transmural arteries was 2.39 (95% confidence interval: 2.24-2.54; I = 99%). The pooled exponent of 2.39 showed very close agreement with the theoretical exponent of 2.33 (7/3) reported by Kassab and colleagues. This exponent may provide a more accurate description of coronary morphometric scaling in human and mammalian coronary arteries, as compared with Murray's original law. This has important implications for the assessment, diagnosis, and interventional treatment of coronary artery disease.

Meta-Analysis
BACKGROUND
Optical coherence tomography (OCT) guidance in percutaneous coronary intervention (PCI) has been shown to improve procedural outcomes. However, evidence supporting its superiority over angiography-guided PCI in terms of clinical outcomes is still emerging and limited. This study aimed to compare the efficacy and safety of OCT-guided PCI versus angiography-guided PCI in patients with coronary artery disease (CAD).
METHODS
A systematic search of electronic databases was conducted to identify randomized control trials (RCTs) comparing the clinical outcomes of OCT-guided and angiography-guided PCI in patients with CAD. Clinical endpoints including all-cause mortality, myocardial infarction (MI), target lesion revascularization (TLR), stent thrombosis and major adverse cardiac events (MACE) were assessed.
RESULTS
Eleven RCTs, comprising 2,699 patients in the OCT-guided group and 2,968 patients in the angiography-guided group met inclusion criteria. OCT-guided PCI was associated with significantly lower rates of cardiovascular death(RR 0.56; 95%CI: 0.32-0.98; p = 0.04; I = 0%), stent thrombosis(RR 0.56; 95%CI: 0.33-0.95; p = 0.03; I = 0%), and MACE (RR 0.79; 95%CI: 0.66-0.95; p = 0.01; I = 5%). The incidence of all-cause death (RR 0.71; 95%CI: 0.49-1.02; p = 0.06; I = 0%), myocardial infarction (RR 0.86; 95%CI: 0.67-1.10; p = 0.22; I = 0%) and TLR (RR 0.98; 95%CI: 0.73-1.33; p = 0.91; I = 0%) was non-significantly lower in the OCT-guided group.
CONCLUSIONS
Among patients undergoing PCI, OCT-guided PCI was associated with lower incidences of cardiovascular death, stent thrombosis and MACE compared to angiography-guided PCI.

Meta-Analysis
BACKGROUND
Coronary pressure indices to assess coronary artery disease are currently underused in patients with aortic stenosis due to many potential physiological effects that might hinder their interpretation. Studies with varying sample sizes have provided us with conflicting results on the effect of transcatheter aortic valve replacement (TAVR) on these indices. The aim of this meta-analysis was to study immediate and long-term effects of TAVR on fractional flow reserve (FFR) and nonhyperemic pressure ratios (NHPRs).
METHODS AND RESULTS
Lesion-specific coronary pressure data were extracted from 6 studies, resulting in 147 lesions for immediate change in FFR analysis and 105 for NHPR analysis. To investigate the long-term changes, 93 lesions for FFR analysis and 68 for NHPR analysis were found. Lesion data were pooled and compared with paired tests. Immediately after TAVR, FFR decreased significantly (-0.0130±0.0406 SD, : 0.0002) while NHPR remained stable (0.0003±0.0675, : 0.9675). Long-term after TAVR, FFR decreased significantly (-0.0230±0.0747, : 0.0038) while NHPR increased nonsignificantly (0.0166±0.0699, : 0.0543). When only borderline NHPR lesions were considered, this increase became significant (0.0249±0.0441, : 0.0015). Sensitivity analysis confirmed our results in borderline lesions.
CONCLUSIONS
TAVR resulted in small significant, but opposite, changes in FFR and NHPR. Using the standard cut-offs in patients with severe aortic stenosis, FFR might underestimate the physiological significance of a coronary lesion while NHPRs might overestimate its significance. The described changes only play a clinically relevant role in borderline lesions. Therefore, even in patients with aortic stenosis, an overtly positive or negative physiological assessment can be trusted.

Meta-Analysis Review
BACKGROUND
Debates persist regarding the optimal duration of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) in coronary artery disease (CAD). Recent trials have introduced a novel approach involving P2Y12 inhibitor monotherapy with ticagrelor or clopidogrel, after a short DAPT. However, the effectiveness and safety of this strategy remains to be established. We aimed to perform a meta-analysis comparing monotherapy with P2Y12 inhibitors versus standard DAPT in patients undergoing PCI at 12 months.
METHODS
Multiple databases were searched. Six RCTs with a total of 24877 patients were included. The primary endpoint was all-cause mortality at 12 months of follow-up. The secondary endpoints were cardiovascular mortality, myocardial infarction, probable or definite stent thrombosis, stroke events, and major bleeding. The study is registered with PROSPERO (CRD42024499529).
RESULTS
Monotherapy with P2Y12 inhibitor ticagrelor significantly reduced both allcause mortality (HR 0.71, 95 CI [0.55-0.91], P = 0.007) and cardiovascular mortality (HR 0.66, 95% CI [0.49-0.89], P = 0.006) compared to standard DAPT. In contrast, clopidogrel monotherapy did not demonstrate a similar reduction. The decrease in mortality associated with ticagrelor was primarily due to a lower risk of major bleeding (HR 0.56, 95% CI [0.43-0.72], P < 0.001), while the risk of myocardial infarction (MI) remained unchanged (HR 0.90, 95% CI [0.73-1.11], P = 0.32). The risk of stroke was found to be similar across treatments.
CONCLUSIONS
In comparison to standard DAPT, P2Y12 inhibitor monotherapy with ticagrelor may lead to a reduced mortality. The clinical benefits are driven by a reduction of bleeding risk without ischemic risk trade-off.

Meta-Analysis Comparative Study Review
Despite recent advancements, challenges persist in determining the optimal stenting strategy for LM bifurcation disease. Hence, this systematic review aims to compare single provisional and systematic dual stenting for managing LM bifurcation disease. A systematic search was performed until January 14, 2024. For the effect measure, risk ratios (RRs) was calculated. This study included 22 studies with 10776 participants. The all-cause mortality and cardiovascular mortality revealed comparable outcomes between provisional and dual-systematic stenting (RR 1.13, CI95 %: 0.87-1.47, p 0.36, I 59 %; RR 1.16, CI95 %: 0.73-1.84, p 0.63, I 80 %). In addition, MACE, MI, TLR, TVR, and in stent thrombosis also showed similar findings. Subgroup analysis revealed that cohort studies was the source of heterogeneity in all-cause mortality, stent thrombosis, and TLR. This meta-analysis suggests comparable outcomes between provisional and dual-systematic stenting in managing LM bifurcation disease. Further study is needed to validate the outcomes of novel techniques.
