Abstract Background Recently, sclerostin, a bone-derived protein, has been shown to play a key role in atherosclerosis progression. However, few studies have investigated the influence of sclerostin on cardiovascular disease prognosis. We investigated the relationship between serum sclerostin levels and adverse outcomes in elderly patients with stable coronary artery disease (SCAD) who were undergoing percutaneous coronary intervention (PCI). Methods We enrolled 310 elderly SCAD patients who underwent PCI in this study and followed them 3 years. According to the median serum sclerostin levels, subjects were stratified into a low sclerostin (low scl) group (n = 144) and a high sclerostin (high scl) group (n = 166). Time-to-event analyses were performed with the Kaplan–Meier method. Associations between sclerostin levels and main adverse cardiovascular and cerebrovascular events (MACCEs) and mortality were evaluated by Cox multivariate regression analysis. The prognostic power of predictive models was verified by the concordance index and receiver operating characteristic curve analysis. Results The high scl group had a significantly higher MACCE-free rate and better survival than the low scl group. Serum sclerostin was an independent predictor and could improve the prognostic power for adverse outcomes. In addition, serum sclerostin levels were significantly associated with bone turnover markers, a lower presence of multivessel disease and a lower CCS angina class. Conclusions Serum sclerostin is a prognostic parameter for predicting and intervening in the adverse outcomes of elderly SCAD patients undergoing PCI, which may be explained by its potential role in the bone–vascular axis.

Coronary artery disease (CAD) is a systemic chronic inflammatory disease, and serum fibrinogen and albumin are 2 important factors in systemic inflammation. We aimed to investigate the relationship between the fibrinogen–albumin ratio (FAR) and outcomes in patients with CAD who underwent percutaneous coronary intervention (PCI). All patients were from the Clinical Outcomes and Risk Factors of Patients with Coronary Heart Disease after PCI (CORFCHD-PCI) study, which is a retrospective cohort study (Identifier: ChiCTR-ORC-16010153) that includes a total of 6050 patients with CAD after PCI from January 2008 to December 2016. A total of 5829 patients with CAD after PCI were recruited in the present study. They were divided into 2 groups according to the FAR cutoff value, which was calculated using a receiver operating characteristic curve, a low group (FAR < 0.095, n = 3811), and a high group (FAR ≥ 0.095, n = 2018). The average follow-up time was 35.9 ± 22.6 months. The multivariate Cox proportional hazards model showed that FAR was independently correlated with all-cause mortality (adjusted hazard ratio [HR] = 1.432 [1.134-1.808], P = .003), cardiac mortality (adjusted HR = 1.579 [1.218-2.047], P = .001), major adverse cardiac and cerebrovascular events (adjusted HR = 1.296 [1.125-1.494], P < .001), major adverse cardiac events (adjusted HR = 1.357 [1.170-1.572], P < .001), and heart failure (adjusted HR = 1.540 [1.135-2.091], P = .006). The present study indicated that the FAR was associated with adverse outcomes in patients with CAD who underwent PCI.

Гены тромбообразования и фолатного обмена играют важную роль в развитии и прогрессии ишемической болезни сердца (ИБС). Однако о возможной роли полиморфных маркеров в рецидиве ИБС после чрескожного коронарного вмешательства (ЧКВ) известно недостаточно. Цель исследования: Оценить роль генетических факторов системы тромбообразования и фолатного обмена (полиморфных маркеров генов F5, F2, F13A1, PAI1, HPA1, MTHFR, FGB ), в возобновление клиники ИБС после ЧКВ. Методика: Исследование проводили с использованием выборки из 90 больных ИБС в возрасте от 40 до 75 лет: 75 пациентов после планового ЧКВ (60 мужчин и 15 женщин) и 15 лиц после экстренного ЧКВ (12 мужчин и 3 женщины). Молекулярно-генетическое исследование было выполнено с помощью комплекта реагентов «Сердечно-сосудистые заболевания СтрипМетод»® (ViennaLab Diagnostics GmbH, Австрия), выявляющие следующие варианты: F5, F2, F13A1, PAI1, HPA1, MTHFR, FGB . Результаты: В результате исследования была показана ассоциация полиморфного маркера G103T ( Val34Leu ) гена F13A1 (фактор свертываемости крови 13, субъединица A1) с развитием рецидивирующего состояния ИБС после ЧКВ. Выявлены статистически значимые различия в распределении частот генотипов полиморфного маркера Val34Leu гена F13A1 . Показано, что частота генотипа Val/Val у пациентов с осложнениями была выше, чем у пациентов без таковых: 0,700 и 0,400 соответственно (c = 7,78; p = 0,020), при этом генотип Val/Val проявил себя как фактор риска развития осложнений: ОШ = 3,50 (95%ДИ 1,37-8,93). При сравнении аллелей выявили, что частота аллеля L у больных с осложнениями была ниже, чем у лиц без таковых: 0,167 и 0,375 соответственно (p = 0,004), и носительство аллеля L уменьшало вероятность развития осложнений: ОШ = 0,33 (95%ДИ 0,15-0,72). Заключение: Носительство варианта 34V гена F13A1 , кодирующего A-субъединицу фактора свёртывания 13, предрасполагает к возобновлению клинических проявлений ИБС после ЧКВ. Genes of thrombosis and folate metabolism play an important role in development and progression of coronary artery disease (CAD). However, a possible role of polymorphic markers in CAD relapse following percutaneous coronary intervention (PCI) is not sufficiently understood. Background. Reports have indicated an association of genetic factors generally related with thrombophilia and recurrence of symptoms for coronary artery disease (CAD) following a percutaneous coronary intervention (PCI) due to restenosis and in-stent thrombosis. However, the relapse can also be caused by progression of atherosclerosis and endothelial dysfunction in unoperated blood vessels. Aim: To assess the role of genetic risk factors involved in thrombosis and folate metabolism (polymorphic markers of F5, F2, F13A1, PAI1, HPA1, MTHFR, and FGB genes) in recurrence of CAD symptoms after PCI. Methods: The study included 90 patients with CAD aged 40-75; 75 of these patients had undergone elective PCI (60 men and 15 women) and 15 patients - emergency PCI (12 men and 3 women). Molecular genetic tests were performed using a CVD StripAssays® reagent kit (ViennaLab Diagnostics GmbH, Austria) to identify the following genetic variations: F5, F2, F13A1, PAI1, HPA1, MTHFR, and FGB . Results: The study results showed a significant association of the G103T ( Val34Leu ) polymorphism in the F13A1 gene with relapses of IHD after PCI. Significant differences were found in genotype distribution frequencies of the Val34Leu polymorphism in the F13A1 gene. The frequency of Val / Val genotype was higher in patients with complications than without complications, 0.700 and 0.400, respectively (c = 7.78, p = 0.020). Furthermore, the Val/Val genotype can be classified as a risk factor for complications (OR = 3.50; 95% CI, 1.37-8.93). The L allele frequency was lower in patients with complications than in those without complications (0.167 and 0.375, respectively, p = 0.004), and carriage of the L allele reduced the likelihood of complications (OR = 0.33; 95% CI 0.15-0.72). Conclusion: Carriage of the 34V variant in the F13A1 gene that encodes the coagulation factor XIII A subunit predisposes to a relapse of CAD symptoms after PCI.

Coronary artery disease (CAD) remains the leading cause of cardiovascular death in octogenarians. This group of patients represents nearly a fifth of all patients treated with percutaneous coronary intervention (PCI) in real-world practice. Octogenarians have multiple risk factors for CAD and often greater myocardial ischemia than younger counterparts, with a potential of an increased benefit from myocardial revascularization. Despite this, octogenarians are routinely under-treated and belittled in clinical trials. Age does make a difference to PCI outcomes in older people, but it is never the sole arbiter of any clinical decision, whether in relation to the heart or any other aspect of health. The decision when to perform revascularization in elderly patients and especially in octogenarians is complex and should consider the patient on an individual basis, with clarification of the goals of the therapy and the relative risks and benefits of performing the procedure. In ST-segment elevation myocardial infarction (MI), there is no upper age limit regarding urgent reperfusion and primary PCI must be the standard of care. In non-ST-segment elevation acute coronary syndromes, a strict conservative strategy must be avoided; whereas the use of a routine invasive strategy may reduce the occurrence of MI and need for revascularization at follow-up, with no established benefit in terms of mortality. In stable CAD patients, invasive therapy on top of the optimal medical therapy seems better in symptom relief and quality of life. This review summarizes the available data on percutaneous revascularization in the elderly patients and particularly in octogenarians, including practical considerations on PCI risk secondary to ageing physiology. We also analyse technical difficulties met when considering PCI in this cohort and the ongoing need for further studies to ameliorate risk stratification and eventually outcomes in these challenging patients.

Abstract Purpose Wire-based coronary physiology pullback performed before percutaneous coronary intervention (PCI) discriminates coronary artery disease (CAD) distribution and extent, and is able to predict functional PCI result. No research investigated if quantitative flow ratio (QFR)–based physiology assessment is able to provide similar information. Methods In 111 patients (120 vessels) treated with PCI, QFR was measured both before and after PCI. Pre-PCI QFR trace was used to discriminate functional patterns of CAD (focal, serial lesions, diffuse disease, combination). Functional CAD patterns were identified analyzing changes in the QFR virtual pullback trace (qualitative method) or after computation of the QFR virtual pullback index (QVPindex) (quantitative method). QVPindex calculation was based on the maximal QFR drop over 20 mm and the length of epicardial coronary segment with QFR most relevant drop. Then, the ability of the different functional patterns of CAD to predict post-PCI QFR value was tested. Results By qualitative method, 51 (43%), 20 (17%), 15 (12%), and 34 (28%) vessels were classified as focal, serial focal lesions, diffuse disease, and combination, respectively. QVPindex values >0.71 and ≤0.51 predicted focal and diffuse patterns, respectively. Suboptimal PCI result (post-PCI QFR value ≤0.89) was present in 22 (18%) vessels. Its occurrence differed across functional patterns of CAD (focal 8% vs. serial lesions 15% vs. diffuse disease 33% vs. combination 29%, p=0.03). Similarly, QVPindex was correlated with post-PCI QFR value (r=0.62, 95% CI 0.50–0.72). Conclusion Our results suggest that functional patterns of CAD based on pre-PCI QFR trace can predict the functional outcome after PCI.
