[PMID: 35685647 PMCID: PMC9171111 DOI: 10.3389/fphar.2022.816059] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Accepted: 02/21/2022] [Indexed: 11/13/2022] Open
Abstract
Background: In stent restenosis (ISR) is one of the major complications after stent implantation. Thus, there is a growing interest in identifying a biomarker for the onset of ISR. High levels of serum homocysteine (Hcy) have been associated with the progression of cardiovascular disease. Therefore, the study was carried out to quantify the correlation between serum Hcy and ISR severity. Compared with coronary angiography (CAG), Hcy levels provided a significantly better clinical detection of ISR severity after PCI. Methods: A total of 155 patients were recruited from Shanxi Bethune hospital, from 6 months to 2 years post PCI. Serum Hcy levels and postoperative angiography results were used to differentiate the patients into two experimental groups: ISR (>50% diametrical stenosis), and non-ISR. The non-ISR included two subgroups: intimal hyperplasia (10–50% diametrical stenosis), and recovery (<10% diametrical stenosis). In addition, a group of 80 healthy individuals was used as a negative control. The correlation between homocysteine level and ISR severity t was analyzed for all groups. In addition, the correlation between serum Hcy level and the severity of ISR in the experimental group was analyzed by the Pearson correlation test. Results: The serum Hcy level in the experimental group and control group was determined to be (20.21 ± 11.42) μmol/L and (15.11 ± 10.25) μmol/L respectively. The level of serum Hcy in the experimental group was significantly higher than in the control group (t-value of 2.385; p-value of 0.019). The serum Hcy level in the restenosis and the intimal hyperplasia group was (25.72 ± 13.71) μmol/L and (17.35 ± 7.70) μmol/L respectively. The serum Hcy level in the restenosis group was significantly higher than in the intimal hyperplasia group (t-value of 2.215; p-value of 0.033). The level of serum Hcy in the group without a plaque in the stent was (16.30 ± 6.08) μmol/L, whereas in the control group was (15.11 ± 10.25) μmol/L. The no plaque group had a slightly higher serum Hcy level than the control group (t-value of 0.634; p-value of 0.528). All included patients were divided into four quartiles based on the serum Hcy concentration: quartile 1 (8.90–13.20 μmol/L), quartile 2 (13.30–16.45 μmol/L), quartile 3 (16.60–24.25 μmol/L) and quartile 4 (24.30-65.30 μ mol/L). The incidence of ISR was 5, 6.25, 7.5 and 15%, in the 1,2,3 and four quartiles respectively. The serum Hcy level in the experimental group was (20.21 ± 11.42) μmol/L, the severity of in-stent restenosis was (0.25 ± 0.31), (R-value was 0.234; p-value was 0.037), indicating a correlation between serum Hcy and the severity of restenosis (p < 0.05). Taking coronary angiography as the gold standard, a ROC curve analysis was performed on the serum Hcy levels for the experimental group. The area under the curve (AUC) was 0.718 (95% CI 0.585-0.854, p < 0.001), indicating that the serum Hcy concentration could predict ISR. On the ROC curve, the best critical value of serum Hcy concentration for predicting ISR was 20.05 μmol/L, with a sensitivity of 45% and specificity of 88.1%. Conclusion: A positive correlation was observed between homocysteine and the severity of restenosis after PCI, The level of Hcy could serve as a predictive biomarker for the severity of ISR.

[PMID: 33549433 DOI: 10.1016/j.numecd.2020.12.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Revised: 10/03/2020] [Accepted: 12/03/2020] [Indexed: 11/25/2022]
Abstract
BACKGROUND AND AIMS Dual antiplatelet therapy (DAPT) and Renin-angiotensin system inhibitors (RASi) represent the cornerstone in the treatment of patients undergoing percutaneous coronary interventions (PCI), mainly after an acute ischemic event. However, high-on treatment residual platelet reactivity (HRPR), is not infrequent despite optimal medical treatment. Homocysteine (Hcy) is a metabolite of methionine catabolism linked to atherothrombosis. Recently, a potential crosstalk between RAS and Hcy has been suggested, potentially favouring platelet aggregation and cardiovascular disease.Therefore, we aimed to investigate the impact of RASi on Hcy levels and platelet aggregation in patients on DAPT after PCI. METHODS AND RESULTS Patients undergoing PCI on DAPT with ASA plus an ADP-antagonist (clopidogrel, ticagrelor or prasugrel), were included. RASi comprised angiotensin converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB). Aggregation tests were performed by Multiple Electrode Aggregometry. We included 1210 patients, of whom 862 (71.2%) were on treatment with RASi. Overall, DAPT composition was ASA+clopidogrel in 566 (46.8%) patients, ASA+ticagrelor in 428 (35.4%) and ASA+prasugrel in 216 (17.9%). Median values of Hcy were higher in RASi patients (p = 0.006), who displayed a higher percentage of Hcy above the median value (52.4% vs. 44.8%, p = 0.019, adjustedOR [95%CI] = 1.40 [1.04-1.88], p = 0.027). No differences in HRPR rate were found according to RASi use for ASPI test (3.6% vs. 3.3%, p = 0.88) and ADP test (25.6% vs. 24.3%,p = 0.62; adjustedOR [95%CI] = 1.23 [0.89-1.70], p = 0.220) and according to ADP-antagonist type. A direct linear relationship was observed between platelet reactivity and Hcy in both patients receiving RASi and untreated ones, with higher values of platelet aggregation being observed in patients with Hcy above the median, independently from RASi administration and DAPT strategy. CONCLUSION In patients on DAPT after PCI, RASi treatment did not emerge as an independent predictor of HRPR. However, the levels of Hcy were significantly elevated in patients on RASi and related to higher values of platelet reactivity, independently from the DAPT strategy.

Association between vitamin D deficiency and serum Homocysteine levels and its relationship with coronary artery disease. J Thromb Thrombolysis 2021; 52:523-531.

Abstract
Homocysteine (Hcy) elevation and vitamin D deficiency have emerged as potential markers of coronary artery disease (CAD). However, even tough hypovitaminosis D has been suggested to interfere with Hcy catabolism, no study has so far addressed the interaction of vitamin D and Hcy and their impact on CAD, that was the aim of present study. A cohort of consecutive patients undergoing coronary angiography in a single center were included and analyzed within the year 2019. Significant CAD was defined as at least 1 vessel stenosis > 50%, while severe CAD as left main and/or three-vessel disease. Hcy and vitamin D levels were assesssed at admission. We included 3150 patients undergoing coronary angiography at our centre, who were divided according to the quartiles values of vitamin D. Patients with lower levels of Vitamin D displayed a higher cardiovascular risk profile and a higher prevalence of CAD. We observed an inverse linear relationship between lower levels of vitamin D and higher Hcy (r = − 0.092, p < 0.001) and a higher prevalence of hyperhomocysteinemia in patients with lower quartiles values of vitamin D (p < 0.001). By forward conditional regression model, low vitamin D appeared as independent predictors of Homocysteine levels above the median (OR[95%CI] = 1.79[1.37–2.33], p < 0.001). In addition, patients with low vitamin D (below the median) and increased Hcy displayed a non-significantly higher rate of CAD (81% vs 77.7%, p = 0.13, adjusted OR[95%CI] = 1.16[0.88–1.54], p = 0.29) but a significant increase in the rate of severe left main/3-vessel CAD (37.4% vs 30.5%, p = 0.005, adjusted OR[95%CI] = 1.29[1.02–1.67], p = 0.04). Among patients with vitamin D levels above the median, Hcy levels did not impact on the prevalence and extent of CAD (77.7 vs 77.2%, p = 0.81, adjusted OR[95%CI] = 0.94[0.73–1.20], p = 0.60 for CAD and 31.8% vs 27.7%, p = 0.08, adjusted OR[95%CI] = 0.97[0.75–1.25], p = 0.81 for severe left main/3-vessel CAD). No significant interaction between Hcy and vitamin D with CAD or severe CAD was observed. The present study shows an independent inverse linear relationship between vitamin D and Hcy values. Moreover, the association of Hcy with the extent of CAD was significant only among patients with hypovitaminosis D, and not in the cohort of subjects with vitamin D levels above the median, suggesting that a normal vitamin D status can prevent the deleterious effects of hyperhomocysteinemia on coronary atherosclerosis, a hypothesis that certainly needs further confirmation in larger randomized trials.

Abstract
BACKGROUND This study observed the incidence of in-stent restenosis (ISR) after percutaneous coronary intervention (PCI) and discusses the risk factors of ISR based on clinical data, coronary angiography, and stent features, to provide a theoretical basis for the prevention and treatment of ISR. MATERIAL AND METHODS We selected 1132 cases who received stent implantation at the Shaanxi People's Hospital from June 2014 to June 2016 and were followed up by coronary angiography within 1 year. Based on coronary angiography, the cases were divided into ISR and non-ISR groups. ISR was defined as a reduction in lumen diameter by over 50% after PCI. The ISR group consisted of 93 cases and the non-ISR group consisted of 1039 cases. Medical history, biochemical indicators, features of coronary artery lesions, and stent status were analyzed retrospectively. Risk factors of ISR were identified by univariate and multivariate logistic regression analyses. RESULTS Among 1132 cases, 93 cases had ISR, with the overall incidence of 8.21%. Univariate and multivariate logistic regression analyses indicated that postoperative hypersensitive C-reactive protein (hs-CRP) levels (OR=2.309, 1.579-3.375 mg/L), postoperative homocysteine (HCY) levels (OR=2.202, 1.268-3.826 μmol/L), history of diabetes (OR=1.955,1.272-3.003), coronary bifurcation lesions (OR=3.785, 2.246-6.377), and stent length (OR=1.269, 1.179-1.365 mm) were independent risk factors of ISR after PCI (P<0.05). CONCLUSIONS Elevated hs-CRP and HCY levels after PCI, history of diabetes, coronary bifurcation lesions, and greater stent length were associated with a higher risk of ISR. Patients with a higher risk of ISR should receive routine follow-up and intense medication management after PCI to control the risk factors and to reduce ISR.

Homocysteine is associated with the progression of non-culprit coronary lesions in elderly acute coronary syndrome patients after percutaneous coronary intervention. J Geriatr Cardiol 2016; 13:299-305. [PMID: 27403138 PMCID: PMC4921541 DOI: 10.11909/j.issn.1671-5411.2016.04.010] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2016] [Revised: 02/26/2016] [Accepted: 02/27/2016] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND The influence of homocysteine (Hcy) on the migration and proliferation of vascular smooth muscle cells has been well established. However, the impact of Hcy levels on the progression of non-culprit coronary lesions (NCCLs) is controversial. This study aims to evaluate whether the plasma level of Hcy is related to the progression of NCCLs after percutaneous coronary stent implantation in elderly patients with acute coronary syndrome (ACS). METHODS A total of 223 elderly patients (≥ 65 years old) with ACS undergoing stent implantation and follow-up coronary angiography were enrolled. Laboratory determination comprised of blood sample evaluation for Hcy was carried out before baseline coronary intervention. The patients were classified into two groups according to the blood Hcy tertiles (≥ 15 mmol/L or < 15 mmol/L). Patients were followed up for 12.2 months. NCCL progression was assessed by three-dimensional quantitative coronary angiography. RESULTS A significantly higher ratio of NCCL progression was observed in the group with baseline Hcy concentrations above 15 mmol/L compared to the group with concentrations below 15 mmol/L (41/127, 32.3% vs. 14/96, 14.6%, P = 0.002). Multivariate Cox regression analysis showed that Hcy and diabetes mellitus were independent risk factors for NCCL progression. The crude hazard ratio (HR) of NCCL progression for Hcy level was 1.056 (95% CI: 1.01-1.104, P = 0.015). The adjusted HR of NCCL progression for Hcy level was 1.024 (95% CI: 1.007-1.042, P = 0.007). The adjusted HR of NCCL progression for diabetes mellitus was 1.992 (95% CI: 1.15-3.44, P = 0.013). CONCLUSIONS Hcy is an independent risk factor for NCCL progression after 12 months of follow-up in elderly patients with ACS who has undergone percutaneous coronary stenting.

Abstract
BACKGROUND Coronary artery disease (CAD) still represents the major cause of mortality in developed countries. Large research programs have been focused on the identification of new risk factors to prevent CAD, with special attention to homocysteine (Hcy), due to the known associated increased thrombogenicity, oxidative stress status and endothelial dysfunction. However, controversy still exists on the association between Hcy and CAD. Therefore, aim of the current study was to investigate the association of Hcy with the prevalence and extent of CAD in a large consecutive cohort of patients undergoing coronary angiography. METHODS Our population is represented by a total of 3056 consecutive patients undergoing coronary angiography between at the Azienda Ospedaliera "Maggiore della Carità", Novara, Italy. Fasting samples were collected for homocysteine levels assessment. Coronary disease was defined for at least 1 vessel stenosis>50% as evaluated by QCA. RESULTS Study population was divided according to Hcy tertiles (<13,3, 13,3-18.2, >18.2nmol/ml). High plasmatic level of homocysteine was related with age (p<0.001), male gender (p<0.001), hypertension (p<0.001) renal failure (p<0.001), family history of CAD (p<0.001), previous cerebrovascular accident (p<0.001), previous MI (p=0.002), previous CABG (p=0.003), ejection fraction (p<0.001), higher baseline creatinine (p<0.001), in treatment with nitrates (p<0.001), calcium antagonists (p<0.001), diuretics (p<0.001), Ace inhibitors (ACE-I) (p=0.006), Clopidogrel (p=0.05), haemoglobin (p=0.001), white blood cells (WBC) count (p=0.008), total cholesterol (p=0.04), Low-Density Lipoproteins (LDL) (p=0.01). A significant relationship was found between Hcy levels and the extent of coronary artery disease (71.8% vs 77.8% vs 77.4%, OR[95%CI]=1.18[1.11-1.252.], p<0.001 and severe CAD (23.6% vs 29.5% vs 32.1%, OR [95%CI]=1.275 [1.209-1.344], p<0.001). Elevated Hcy was significantly associated with increased risk of CAD (adjusted OR[95%CI]=1.087[1.009-1.171], p=0.02 and severe CAD (adjusted OR [95%CI]=1.07 [1.01-1.16, P=0.04]). The results were confirmed in the majority of high risk subsets of patients. CONCLUSIONS This study showed that high levels of plasmatic Hcy are independently associated with CAD. Further large studies are certainly needed to explore the adjunctive benefits from vitamin administration in patients with elevated Hcy to prevent the occurrence and progression of CAD.

Abstract
Contrast-induced nephropathy (CIN) is a common complication in patients with impaired kidney function undergoing coronary angiography/angioplasty. We evaluated whether elevated homocysteine (known to be associated with free radical generation and oxidative stress) increases the risk of CIN. Patients (n = 876) with creatinine clearance <60 mL/min undergoing coronary angiography or percutaneous coronary intervention (PCI) were divided into tertiles of homocysteine levels. Contrast-induced nephropathy was defined as ≥0.5 mg/dL or ≥25% creatinine increase 24 to 48 hours post-PCI. A significant relationship was observed between homocysteine levels and the risk of CIN ( P = .033), confirmed after correction for baseline confounding factors, adjusted odds ratio, OR (95% confidence interval, [CI]) = 1.68 (1.09-2.59), P = .019. This association was also significant applying the new definition of contrast-induced acute kidney injury (11.9% in group 1, 10.4% in group 2, and 22.8% in group 3; P < .001), adjusted OR (95% CI) = 1.96 (1.3-2.95), P = .001. Future studies are needed to confirm our findings and to define the role of homocysteine in CIN.

Abstract
BACKGROUND AND AIM Pro-thrombotic status and platelet hyperreactivity still represent an important challenge for periprocedural myocardial infarction (PMI) after coronary stenting. Hyperhomocysteinemia has been suggested to increase the risk of cardiovascular events. The genetic variant of methylenetetrahydrofolate reductase (MTHFR) 677 C > T has been associated to reduced function of the enzyme, thus inducing hyperhomocysteinemia. In our study we investigated whether MTHFR 677 C > T polymorphism is associated with increased risk of periprocedural MI in patients undergoing coronary stenting. METHODS AND RESULTS We included 778 patients undergoing PCI. Homocysteinemia and genetic status were assessed at admission for all patients. Myonecrosis biomarkers were dosed at intervals from 6 to 48 h, PMI was defined as CKMB increase by 3 times the ULN or 50% of pre-PCI value, periprocedural myonecrosis for troponin I increase by 3 times the ULN or by 50% of the baseline. As many as 521 patients carried the MTHFR-T allele. No difference was found for main demographical and clinical features nor for biochemistry parameters, but for higher rate of statins treatment (p = 0.03) in T-carriers. Polymorphic patients displayed significantly higher levels of homocysteine (p = 0.005), with additive effect of the mutated T-alleles. Angiographic and procedural features were similar according to genetic status. MTHFR677T was not associated with periprocedural myocardial infarction (adjusted OR = 0.97[0.67-1.4], p = 0.87) or myonecrosis (adjusted OR = 1.03[0.83-1.36], p = 0.82). Same results were found at subgroup analysis in higher-risk subsets of patients. CONCLUSION Our study showed that among patients undergoing PCI, MTHFR 677 C > T polymorphism is associated to higher homocysteine levels, but does not influence the risk of periprocedural myocardial infarction.

Abstract
Chronic venous ulceration (CVU) is the major cause of chronic wounds of lower extremities, and is a part of the complex of chronic venous disease. Previous studies have hypothesised that several thrombophilic factors, such as hyperhomocysteinaemia (HHcy), may be associated with chronic venous ulcers. In this study, we evaluated the prevalence of HHcy in patients with venous leg ulcers and the effect of folic acid therapy on wound healing. Eighty-seven patients with venous leg ulcers were enrolled in this study to calculate the prevalence of HHcy in this population. All patients underwent basic treatment for venous ulcer (compression therapy ± surgical procedures). Patients with HHcy (group A) received basic treatment and administered folic acid (1·2 mg/day for 12 months) and patients without HHcy (group B) received only basic treatment. Healing was assessed by means of computerised planimetry analysis. The prevalence of HHcy among patients with chronic venous ulcer enrolled in this study was 62·06%. Healing rate was significantly higher (P < 0·05) in group A patients (78·75%) compared with group B patients (63·33%). This study suggests a close association, statistically significant, between HHcy and CVU. Homocysteine-lowering therapy with folic acid seems to expedite wound healing. Despite these aspects, the exact molecular mechanisms between homocysteine and CVU have not been clearly defined and further studies are needed.

Abstract
Homocysteine has been implicated in promoting atherosclerotic and thrombotic vascular disease. During the last decade, the utility of homocysteine in predicting risk for atherothrombotic vascular disease has been evaluated in several observational studies in a large number of patients. These studies show that the overall risk for vascular disease is small, with prospective, longitudinal studies reporting a weaker association between homocysteine and atherothrombotic vascular disease compared to retrospective case-control and cross-sectional studies. Furthermore, randomized controlled trials of homocysteine-lowering therapy have failed to prove a causal relationship. On the basis of these results, there is currently insufficient evidence to recommend routine screening and treatment of elevated homocysteine concentrations with folic acid and other vitamins to prevent atherothrombotic vascular disease. This review outlines the metabolism and pathophysiology of homocysteine, highlights the results of homocysteine observational and interventional trials, and presents areas of uncertainty and potential future work.
