RESUMO
BACKGROUND: The prognostic impact of complete coronary revascularization relative to non-invasive testing methods is unknown. OBJECTIVES: To assess the association between completeness of revascularization defined by CTA-derived fractional flow reserve (FFRCT) and cardiovascular outcomes in patients with stable angina. METHODS: Multicenter 3-year follow-up study of patients with new onset stable angina and ≥ 30% stenosis by CTA. The lesion-specific FFRCT value (two cm-distal-to-stenosis) was registered in all vessels with stenosis and considered abnormal when ≤ 0.80. Patients with FFRCT ≤ 0.80 were categorized as: Completely revascularized (CR-FFRCT), all vessels with FFRCT ≤ 0.80 revascularized; incompletely revascularized (IR-FFRCT), ≥ 1 vessels with FFRCT ≤ 0.80 non-revascularized. Early revascularization (< 90 days from index CTA) categorized vessels as revascularized. The primary endpoint comprised cardiovascular death and non-fatal myocardial infarction; the secondary endpoint vessel-specific late revascularization and non-fatal myocardial infarction. RESULTS: Amongst 900 patients and 1759 vessels, FFRCT was ≤ 0.80 in 377 (42%) patients, 536 (30%) vessels; revascularization was performed in 244 (27%) patients, 340 (19%) vessels. Risk of the primary endpoint was higher for IR-FFRCT (15/210 [7.1%]) compared to CR-FFRCT (4/167 [2.4%]), RR: 2.98; 95% CI: 1.01-8.8, p â= â0.036, and to normal FFRCT (3/523 [0.6%]), RR: 12.45; 95% CI: 3.6-42.6, p â< â0.001. Incidence of the secondary endpoint was higher in non-revascularized vessels with FFRCT ≤ 0.80 (29/250 [12%]) compared to revascularized vessels with FFRCT ≤ 0.80 (5/286 [1.7%]), p â= â0.001, and to vessels with FFRCT > 0.80 (10/1223 [0.8%]), p â< â0.001. CONCLUSION: Incomplete revascularization of patients with lesion-specific FFRCT ≤ 0.80 is associated to unfavorable cardiovascular outcomes compared to those with complete revascularization or FFRCT > 0.80.

ETHNOPHARMACOLOGICAL RELEVANCE: Cardiovascular and cerebrovascular diseases are the leading causes of death worldwide and interact closely with each other. Danhong Injection (DHI) is a widely used preparation for the co-treatment of brain and heart diseases (CTBH). However, the underlying molecular endotype mechanisms of DHI in the CTBH remain unclear. AIM OF THIS STUDY: To elucidate the underlying endotype mechanisms of DHI in the CTBH. MATERIALS AND METHODS: In this study, we proposed a modular-based disease and drug-integrated analysis (MDDIA) strategy for elucidating the systematic CTBH mechanisms of DHI using high-throughput transcriptome-wide sequencing datasets of DHI in the treatment of patients with stable angina pectoris (SAP) and cerebral infarction (CI). First, we identified drug-targeted modules of DHI and disease modules of SAP and CI based on the gene co-expression networks of DHI therapy and the protein-protein interaction networks of diseases. Moreover, module proximity-based topological analyses were applied to screen CTBH co-module pairs and driver genes of DHI. At the same time, the representative driver genes were validated via in vitro experiments on hypoxia/reoxygenation-related cardiomyocytes and neuronal cell lines of H9C2 and HT22. RESULTS: Seven drug-targeted modules of DHI and three disease modules of SAP and CI were identified by co-expression networks. Five modes of modular relationships between the drug and disease modules were distinguished by module proximity-based topological analyses. Moreover, 13 targeted module pairs and 17 driver genes associated with DHI in the CTBH were also screened. Finally, the representative driver genes AKT1, EDN1, and RHO were validated by in vitro experiments. CONCLUSIONS: This study, based on clinical sequencing data and modular topological analyses, integrated diseases and drug targets. The CTBH mechanism of DHI may involve the altered expression of certain driver genes (SRC, STAT3, EDN1, CYP1A1, RHO, RELA) through various enriched pathways, including the Wnt signaling pathway.

Objectives: Although the association of Atherogenic index of plasma (AIP) with coronary artery disease (CAD) and atherosclerosis is known, the relationship between AIP and in-stent restenosis (ISR) remains unclear. We aimed to investigate the relationship between AIP and ISR in patients with stable angina pectoris (SAP) treated with drug-eluting stent (DES). Methods: Patients with a history of DES implantation following stable angina were evaluated between January 2015 and November 2019 in this observational and retrospective study. 608 eligible patients were dichotomized into ISR+ (n=241) and ISR- (n=367). ISR was defined as the presence of 50% or greater stenosis. AIP was defined as log [TG/HDL-C]. Results: AIP levels were significantly higher in patients who developed ISR compared with those who did not (0.33 [0.15-0.52] vs 0.06 [-0.08-0.21] respectively, p<0.001). The AUC value of AIP levels for predicting ISR was 0.746 (p<0.001). Multivariate logistic regression analysis revealed that AIP, diabetes mellitus, higher LDL-C levels and lower LVEF values were independently associated with ISR. Conclusion: Multivariate analysis revealed that AIP was strongly independently associated with ISR. Using this novel inexpensive and easily calculable index may provide early recognition of ISR in patients with SAP who were treated with DES.
RESUMO
Multivessel coronary artery disease (MV-CAD) remains a prevalent and serious health concern despite advances in treatment. Early identification and risk stratification are crucial for optimizing treatment. The CRP-to-albumin ratio (CAR) has emerged as a promising biomarker in various inflammatory diseases. This study investigated the potential of CAR as a marker for MV-CAD. We retrospectively analyzed 1360 patients with suspected CAD. Patients were divided into three groups based on CAR tertiles. Logistic regression analyses were carried out to estimate the association between MHR and MV-CAD. Elevated CAR levels were significantly associated with an increased prevalence of CAD (p < 0.001), severe CAD (p < 0.001), and MV-CAD (p < 0.001). Patients with the highest CAR tertile had five times higher odds of MV-CAD compared to the lowest tertile (p < 0.001). CAR demonstrated moderate accuracy in predicting MV-CAD (AUC: 0.644, 95% CI: 0.615-0.674, p < 0.001). CAR holds promise as a tool for the early identification and risk stratification of multivessel CAD. Further research is warranted to validate its clinical utility and explore its potential to guide treatment decisions and improve outcomes in patients with this high-risk condition.
RESUMO
BACKGROUND: Stable angina pectoris (SAP) is a clinical condition characterized by reversible and temporary myocardial ischemia and hypoxia. A majority of SAP patients also experience depressive disorders, which adversely affect their disease prognosis and overall quality of life. However, the clinical utility of existing antidepressants is constrained by their side effects. Ginkgo biloba dropping pill (GBDP), a Chinese patented medication, has demonstrated efficacy in the treatment of both coronary heart disease and mental disorders. This prospective, randomized, double-blind, multicenter clinical trial aimed to assess the effectiveness and safety of GBDP as an adjuvant therapy for SAP complicated by depression. METHODS: Participants were randomly assigned in a 1:1 ratio to receive either GBDP or a placebo (5 pills, three times a day) in addition to standard therapy for a duration of 12 weeks. The Seattle Angina Questionnaire (SAQ) was administered every 4 weeks during the treatment, and angina event frequency was assessed weekly. The 36-item Short-Form (SF-36) and Hamilton Depression Scale (HAMD) scores were measured both before and after the treatment. RESULTS: Out of the 72 patients, 68 (n = 34 per group) completed the entire study. At the first visit (4 weeks ± 3 days), the SAQ-Angina Stability score in the GBDP group was significantly higher than that in the placebo group (p < 0.05). While the average weekly frequency of angina episodes in the placebo group notably increased after 12 weeks of treatment (p < 0.05), it displayed an improving trend in the GBDP group (p > 0.05). By the endpoint, each subcategory score of SF-36 in the GBDP group exhibited significant improvement compared to baseline (p < 0.05). The comparison of score improvement between the two groups revealed that the SF-PCS score of the GBDP group was higher than that of the placebo group (p < 0.05). HAMD scores in both groups significantly increased after treatment (p < 0.05). No discernible difference in the incidence of adverse reactions was observed between the two groups (p > 0.05). CONCLUSION: In patients with SAP complicated by depression, GBDP, when combined with standard treatment, rapidly and safely alleviates angina pectoris symptoms. It demonstrates therapeutic potential in enhancing the quality of life and alleviating depressive symptoms.

BACKGROUND: The burden of cardiovascular diseases (CVDs) is increasing worldwide with CVD being one of the leading causes of death, including atherosclerosis, myocardial infarction, cardiomyopathy, and heart failure (HF). Fibroblast growth factor 21 (FGF21) is an endocrine hormone that regulates carbohydrate and lipid metabolism. It exerts direct effects on the cardiovascular system and can serve as an early indicator of CVDs. FGF21's therapeutic properties include reducing obesity, dyslipidaemia, and hyperglycemia, which can help treat metabolic disorders, autophagy, and apoptosis. Atherosclerosis is developed due to chronic inflammatory conditions, and the immune system's reaction to oxidized lipoproteins is mainly responsible for the development of atherosclerosis. FGF21's precise role in the pathogenesis of coronary artery disease (CAD) remains elusive. Aim: This study aimed to assess the role of FGF21 in predicting the severity and magnitude of CAD in individuals diagnosed with stable angina pectoris (SAP). MATERIALS AND METHODS: A prospective cross-sectional study was conducted on 110 consecutive patients with SAP reported to the cardiology department of the Indira Gandhi Institute of Medical Sciences (IGIMS), Patna, India. They were divided into two groups based on coronary angiography findings. Control groups included patients not showing any atherosclerotic lesions and case groups with atherosclerotic lesions. The SYNTAX score is a grading system that measures the location and complexity of coronary arteries using anatomical principles. The Gensini score assessment technique was employed to determine the severity of CAD. We compared serum FGF21 levels,left ventricular ejection fraction (LVEF), and inflammatory biomarker C-reactive protein (CRP) levels between the two groups. Moreover, we examined the correlation between the serum FGF21 level and the SYNTAX and Gensini scores. The statistical analysis was done using Version 23.0 of SPSS Statistics. P-values below 0.05 were considered statistically significant. RESULTS: The study found that the case group had a higher average age and a higher proportion of male patients. The case group had considerably higher levels of FGF21 (166.59 ± 94.49791 pg/mL) compared to the control group (54.13 ± 48.467 pg/mL) (p=0.034). The LVEF exhibited a significant difference between the case and control groups, with mean values of 50.3056 ± 7.8242% and 56.078 ± 5.3987%, respectively (p=0.031). CRP levels were comparable in both groups. The case group had mean values of SYNTAX and Gensini scores of 23.19±7.43 and 50.03±27.30, respectively. We found that there was no statistically significant association between the risk assessments for CAD severity and the levels of serum FGF21 (correlation coefficient r=0.14070, p>0.05, and r=0.206415, p>0.05, respectively) Conclusions: FGF21 is gaining recognition as a prospective addition to the FGF family, potentially playing a significant role in cardiovascular disease, particularly atherosclerosis. A statistically significant difference was seen in the serum FGF21 levels between the case and control groups, indicating that it can help in the diagnosis of CAD. However, there was no apparent correlation found between the serum FGF21 levels and the SYNTAX and Gensini scores. The role of FGF21 in the development of atherosclerosis and whether FGF21 could serve as a reliable marker need to be studied further.
RESUMO
Biomarkers are widely used for the diagnosis and monitoring of cardiovascular disease. However, markers for coronary high-risk plaques have not been identified. The aim of this study was to identify proteins specific to coronary high-risk plaques. Fifty-one patients (71.2 ± 11.1 years, male: 66.7%) who underwent intracoronary optical coherence tomography imaging and provided blood specimens for proteomic analysis were prospectively enrolled. A total of 1470 plasma proteins were analyzed per patient using the Olink® Explore 1536 Reagent Kit. In patients with thin-cap fibroatheroma, the protein expression of Calretinin (CALB2), Corticoliberin (CRH) and Alkaline phosphatase, placental type (ALPP) were significantly increased, while the expression of Neuroplastin (NPTN), Folate receptor gamma (FOLR3) and Serpin A12 (SERPINA12) were significantly decreased. In patients with macrophage infiltration, the protein expressions of Fatty acid-binding protein, intestinal (FABP2), and Fibroblast growth factor 21 (FGF21) were significantly decreased. In patients with lipid-rich plaques, the protein expression of Interleukin-17 C (IL17C) was significantly increased, while the expression of Fc receptor-like protein 3 (FCRL3) was significantly decreased. These proteins might be useful markers in identifying patients with coronary high-risk plaques. Clinical Trial Registration: https://www.umin.ac.jp/ctr/ , UMIN000041692.

BACKGROUND: The association between coronary computed tomography angiography (CTA) derived fractional flow reserve (FFRCT) and risk of recurrent angina in patients with new onset stable angina pectoris (SAP) and stenosis by CTA is uncertain. METHODS: Multicenter 3-year follow-up study of patients presenting with symptoms suggestive of new onset SAP who underwent first-line CTA evaluation and subsequent standard-of-care treatment. All patients had at least one ≥30 â% coronary stenosis. A per-patient lowest FFRCT-value ≤0.80 represented an abnormal test result. Patients with FFRCT ≤0.80 who underwent revascularization were categorized according to completeness of revascularization: 1) Completely revascularized (CR-FFRCT), all vessels with FFRCT ≤0.80 revascularized; or 2) incompletely revascularized (IR-FFRCT) ≥1 vessels with FFRCT ≤0.80 non-revascularized. Recurrent angina was evaluated using the Seattle Angina Questionnaire. RESULTS: Amongst 769 patients (619 [80 â%] stenosis ≥50 â%, 510 [66 â%] FFRCT ≤0.80), 174 (23 â%) reported recurrent angina at follow-up. An FFRCT ≤0.80 vs â> â0.80 associated to increased risk of recurrent angina, relative risk (RR): 1.82; 95 â% CI: 1.31-2.52, p â< â0.001. Risk of recurrent angina in CR-FFRCT (n â= â135) was similar to patients with FFRCT >0.80, 13 â% vs 15 â%, RR: 0.93; 95 â% CI: 0.62-1.40, p â= â0.72, while IR-FFRCT (n â= â90) and non-revascularized patients with FFRCT ≤0.80 (n â= â285) had increased risk, 37 â% vs 15 â% RR: 2.50; 95 â% CI: 1.68-3.73, p â< â0.001 and 30 â% vs 15 â%, RR: 2.03; 95 â% CI: 1.44-2.87, p â< â0.001, respectively. Use of antianginal medication was similar across study groups. CONCLUSION: In patients with SAP and coronary stenosis by CTA undergoing standard-of-care guided treatment, FFRCT provides information regarding risk of recurrent angina.

OBJECTIVE: The aim: To study the risk factors of cardiovascular diseases in patients with coronary heart disease with stable angina pectoris II functional class in combi¬nation with NAFLD. PATIENTS AND METHODS: Materials and methods: The study included 245 patients with a diagnosis of CHD, stable angina pectoris II functional class (FC), who were being treated at the Communal Nonprofit Enterprise «Central City Clinical Hospital¼ of Uzhhorod City Council. We singled out 2 groups of patients: group 1 (n=145) - patients with CHD with stable angina pectoris II FC in combination with NAFLD and group 2 (n=100) - patients with CHD with stable angina pectoris II FC. RESULTS: Results: Analysis of the frequency of occurrence of CVD risk factors in patients with CHD showed that among patients of group 1 there are 50% more people with abdominal obesity, excess body and dyslipidemia. The reliability between the groups in the occurrence of hypertension and type 2 diabetes was not revealed. The obtained results confirm the data that the prevalence of NAFLD increases with increasing body weight and a high degree of obesity increases the risk of its development. CONCLUSION: Conclusions: The most frequent risk factors for CVD in patients with coronary artery disease in combination with NAFLD are hypertension, obesity, and dyslipidemia.

BACKGROUND: Imaging modality-based evidence is limited that compares the extent of coronary arterial repair after percutaneous coronary intervention between patients with stable angina pectoris (SAP) and those with acute coronary syndrome (ACS). METHODS: Between December 2018 and November 2021, a single-center, nonrandomized, observational study was conducted in 92 patients with SAP (n = 42) or ACS (n = 50), who were implanted with Orsiro sirolimus-eluting stent (O-SES) providing a hybrid (active and passive) coating and underwent 1-year follow-up by coronary angioscopy (CAS) after implantation. CAS assessed neointimal coverage (NIC), maximum yellow plaque (YP), and mural thrombus (MT). RESULTS: Baseline clinical characteristics were comparable between the SAP and ACS groups. The follow-up periods were comparable between the two groups (390.1 ± 69.9 vs. 390.6 ± 65.7 days, p = 0.99). The incidences of MT at 1 year after implantation were comparable between the two groups (11.4% vs. 11.1%, p = 0.92). The proportions of "Grade 1" in dominant NIC grades were highest in both groups, and the proportions of maximum YP grades and MT were comparable between the two groups. CONCLUSION: O-SES-induced coronary arterial repair at the site of stent implantation, irrespective of the types of coronary artery disease.

BACKGROUND: The safety of administration of tirofiban, a platelet glycoprotein IIb/IIIa inhibitor, followed by a clopidogrel loading dose in clopidogrel-naïve patients undergoing ad-hoc percutaneous coronary intervention (PCI) is not yet clear. METHODS: In a retrospective observational cohort analysis, clopidogrel-naïve patients undergoing ad-hoc PCI who received a high-dose bolus of tirofiban (25⯵g/kg) followed by a 600-mg clopidogrel loading dose (group 1) were compared with patients undergoing elective PCI who were pretreated with clopidogrel (group 2), between September 2014 and October 2021. The primary outcome was major adverse cardiovascular events (MACE) defined as the composite of death, myocardial infarction, stroke, target-lesion revascularisation and bleeding at 30 days. Secondary outcomes were MACE at 7 days and individual components of the primary outcome at 7 and 30 days. RESULTS: A total of 1404 patients were included: 432 (31%) in group 1 and 972 (69%) in group 2. Median age was 69 years, and 28% were female. At 7day follow-up, MACE occurred in 1.4% in group 1 versus 3.0% in group 2 (pâ¯= 0.08). 30-day MACE were observed in 1.9% in group 1 and 4.2% in group 2 (pâ¯= 0.03). Secondary outcomes were comparable between the groups. Cox regression analysis, corrected for baseline differences, revealed no significant difference in the primary outcome (hazard ratio: 1.8; 95% confidence interval: 0.8-3.9). CONCLUSION: Ad-hoc PCI in clopidogrel-naïve patients who were treated with high-dose bolus of tirofiban followed by a clopidogrel loading dose immediately after the procedure appeared to be safe.
RESUMO
Until recently, it has been generally held that stable angina pectoris (SAP) primarily reflects the presence of epicardial coronary artery stenoses due to atheromatous plaque(s), while acute myocardial infarction (AMI) results from thrombus formation on ruptured plaques. This concept is now challenged, especially by results of the ORBITA and ISCHEMIA trials, which showed that angioplasty/stenting does not substantially relieve SAP symptoms or prevent AMI or death in such patients. These disappointing outcomes serve to redirect attention towards anomalies of small coronary physiology. Recent studies suggest that coronary microvasculature is often both structurally and physiologically abnormal irrespective of the presence or absence of large coronary artery stenoses. Structural remodelling of the coronary microvasculature appears to be induced primarily by inflammation initiated by mast cell, platelet, and neutrophil activation, leading to erosion of the endothelial glycocalyx. This leads to the disruption of laminar flow and the facilitation of endothelial platelet interaction. Glycocalyx shedding has been implicated in the pathophysiology of coronary artery spasm, cardiovascular ageing, AMI, and viral vasculitis. Physiological dysfunction is closely linked to structural remodelling and occurs in most patients with myocardial ischemia, irrespective of the presence or absence of large-vessel stenoses. Dysfunction includes the impairment of platelet and vascular responsiveness to autocidal coronary vasodilators, such as nitric oxide, prostacyclin, and hydrogen sulphide, and predisposes both to coronary vasoconstriction and to a propensity for microthrombus formation. These findings emphasise the need for new directions in medical therapeutics for patients with SAP, as well as a wide range of other cardiovascular disorders.

Objective: We aimed to evaluate the effects of integrated Chinese and Western medical therapeutic modalities on clinical prognosis in a population with stable angina pectoris (SAP) of coronary heart disease (CHD). Methods: In a prospective cohort study, 732 patients with SAP of CHD hospitalized in the Integrated Cardiology Unit of the China-Japan Friendship Hospital From October 2020 to October 2021 were included. The patients were divided into integrated treatment and conventional treatment groups according to whether they had been taking Chinese medicine for more than 6 months per year. The occurrence of composite cardiovascular events (CVEs), including cardiac death, non-fatal myocardial infarction, revascularization, stroke, all-cause death, and readmission due to angina attack, heart failure, or malignant arrhythmia, was recorded during follow-up. The effects of different treatment modalities on prognosis were evaluated using univariate and multifactorial logistic regression. Logistic regression models were evaluated using receiver operating characteristic (ROC) curves. In sensitivity analysis, the correlation between treatment modality and outcome events was corrected by rematching the two groups of patients using the propensity score matching (PSM) method. Results: The data from 690 patients were included in the analysis, with 327 patients in the integrated treatment group and 363 patients in the conventional treatment group. CVEs occurred in 19 patients (5.8%) in the integrated treatment group and 37 patients (10.2%) in the conventional treatment group. The proportion of outcome events was significantly lower in the combination treatment group than in the conventional treatment group (P = 0.037). Covariate correction by multimodal multifactorial logistic regression revealed a lower risk of CVEs in patients receiving integrated therapy compared with conventional therapy (OR = 0.246, 95% CI = 0.097-0.622, P = 0.003). Moreover, a history of renal insufficiency (OR = 3.991, 95% CI = 1.164-13.684, P = 0.028) and a higher Gensini score (OR = 1.039, 95% CI = 1.028-1.050, P < 0.001) were risk factors for the development of CVEs. Model evaluation showed that C-statistic = 0.955 and area under the ROC curve (AUC) = 0.955. After PSM correction, the results still showed that integrated Chinese and Western medical treatment reduced the occurrence of CVEs in patients compared with Western treatment alone (OR = 0.339, 95% CI = 0.131-0.874, P = 0.025). Conclusion: Integrated treatment based on Chinese and Western medicine might improve the prognosis and reduce the risk of CVEs in this disease population.

RESUMO
Background: Long-term use of nitrates for treating stable angina pectoris (SAP) may lead to patients' tolerance to nitrates. As a traditional Chinese medicine, Compound danshen dropping pills (CDDP) is beneficial for patients with SAP. This study aimed to critically assess the efficacy and safety of CDDP vs. nitrates for SAP. Methods: PubMed, Embase, Web of Science, Cochrane library, CNKI, Wanfang Digital Periodicals, and Chinese Science and Technology Periodicals database were searched from inception to April 2023. Randomized controlled trials (RCTs) comparing CDDP with nitrates for SAP were included. The meta-analysis was conducted to estimate the pooled effect. Results: Twenty-nine studies were included for the statistical analysis. The meta-analyses with the random-effect model indicated that CDDP could significantly increase the effective rate in symptom improvement compared with nitrates (Pooled 9 RCTs, OR = 1.95, 95% CI: 1.25-3.05, P = 0.003, duration of 4 weeks; Pooled 4 RCTs, OR = 3.45, 95% CI: 1.84-6.48, P = 0.0001, duration of 6 weeks; Pooled 13 RCTs, OR = 4.02, 95% CI: 2.14-7.57, P < 0.0001, duration of 8 weeks). The meta-analyses with the random-effect model indicated that CDDP could significantly increase the effective rate in electrocardiogram improvement compared with nitrates (Pooled 5 RCTs, OR = 1.60, 95% CI: 1.02-2.52, P = 0.04, duration of 4 weeks; Pooled 3 RCTs, OR = 2.47, 95% CI: 1.60-3.82, P < 0.0001, duration of 6 weeks; Pooled 11 RCTs, OR = 3.43, 95% CI: 2.68-4.38, P < 0.00001, duration of 8 weeks). The incidence of adverse drug reactions in the CDDP group was lower than that in the nitrates group (Pooled 23 RCTs, OR = 0.15, 95% CI: 0.1-0.21, P < 0.00001). The results of the meta-analyses with fixed-effect model were similar with above results. The levels of the evidence ranged from very low to low. Conclusion: The present study suggests that CDDP with the duration of at least 4 weeks can be considered as an alternative to nitrates for treating SAP. However, more high-quality RCTs are still needed to confirm these findings.

RESUMO
Cardiac troponin is a useful test for diagnosing cardiogenic causes in patients with chest pain. However, cardiac troponin levels are often elevated in patients with chest pain due to non-cardiac causes other than coronary artery disease. The purpose of this study was to investigate the prevalence of coronary artery disease (CAD) and its associated factors in patients with chest pain and elevated cardiac troponin I (cTnI). 104 patients (mean age, 65 ± 11 years; 60 [58%] men) who underwent coronary angiography (CAG) for chest pain and elevated cTnI levels were enrolled in this study. All patients had a normal CK-MB range and did not show any ischemic changes on electrocardiography or echocardiography. Patients were classified into two groups according to the presence of CAD (Group 1, n = 62) and the absence of CAD (Group 2, n = 42). Patients were classified into subgroups according to the presence (Group 2a, microvascular angina [MVA], n = 18) and absence (Group 2b, non-angina [NA], n = 25) of angina. CAD was diagnosed in 62 (60%) patients and MVA was suspected in 18 (17%) patients without CAD. Patients with CAD showed elevated blood pressure and slightly decreased heart rate. Diabetes mellitus was more prevalent in patients with CAD and patients without CAD (esp. with MVA) were more likely to be common drinkers. Increased relative wall thickness (RWT) and reduced E' velocity were associated with CAD. High-density lipoprotein (HDL) levels were reduced in patients with CAD and MVA but were higher in patients with NA. Lower HDL level was found to be independently associated with the presence of CAD. Elevated cTn1 levels without other evidence of myocardial ischemia are sufficient for performing CAG in patients with stable chest pain.
RESUMO
BACKGROUND: Currently, in the majority of patients with stable angina pectoris (SAP) treatment consists of optimal medical treatment, potentially followed by coronary angiography and subsequent coronary revascularisation if necessary". Recent work questioned the effectiveness of these invasive procedures in reducing re-events and improving prognosis. The potential of exercise-based cardiac rehabilitation on clinical outcomes in patients with coronary artery disease is well-known. However, in the modern era, no studies compared the effects of cardiac rehabilitation versus coronary revascularisation in patients with SAP. METHODS: In this multicentre randomised controlled trial, 216 patients with stable angina pectoris and residual anginal complaints under optimal medical treatment will be randomised to: 1) usual care (i.e., coronary revascularisation), or 2) a 12-month cardiac rehabilitation (CR) programme. CR consists of a multidisciplinary intervention, including education, exercise training, lifestyle coaching and a dietary intervention with a stepped decline in supervision. The primary outcome will be anginal complaints (Seattle Angina Questionnaire-7) following the 12-month intervention. Secondary outcomes include cost-effectiveness, ischemic threshold during exercise, cardiovascular events, exercise capacity, quality of life and psychosocial wellbeing. DISCUSSION: In this study, we will examine the hypothesis that multidisciplinary CR is at least equally effective in reducing anginal complaints as the contemporary invasive approach at 12-months follow-up for patients with SAP. If proven successful, this study will have significant impact on the treatment of patients with SAP as multidisciplinary CR is a less invasive and potentially less costly and better sustainable treatment than coronary revascularisations.

BACKGROUND: Coronary healed plaques (HPs) reportedly have high vulnerability or show advanced atherosclerosis and a risk of rapid plaque progression. However, the prognosis of stable angina pectoris (SAP) patients with HPs undergoing percutaneous coronary intervention (PCI) remains under-investigated.MethodsâandâResults: We analyzed 417 consecutive lesions from SAP patients undergoing pre- and post-intervention optical coherence tomography (OCT) for which HPs were defined as having a layered appearance. We investigated the differences in clinical and lesion characteristics, and post-PCI outcomes between HPs and non-HPs. To account for differences in clinical characteristics, propensity score matching was performed between the groups. HPs were observed in 216 lesions (51.8%) in the total cohort. In the propensity-matched cohort (n=294), HPs had higher rates of angiographic-B2/C lesions (77.6% vs. 59.2%, P<0.001), OCT-lipid-rich plaques (40.8% vs. 25.9%, P=0.007), macrophages (78.2% vs. 44.2%, P<0.001), greater luminal area stenosis (73.5±11.0% vs. 71.5±10.3%, P=0.002), and a higher prevalence of post-stenting irregular tissue protrusion (45.1% vs. 14.7%, P<0.001) than non-HPs. In the total cohort, target lesion revascularization (TLR)-free survival was poorer for HPs (log-rank test 7.66; P=0.006), and Cox proportional hazards analysis showed HP as an independent predictor of TLR (hazard ratio, 5.98; 95% confidence interval, 1.72-20.82; P=0.005). CONCLUSIONS: In SAP patients, HPs had greater complexity of lesions and higher vulnerability, which may have contributed to the poorer post-PCI outcomes.

Background and Objectives: Coronary slow flow (CSF) is an angiographic phenomenon characterized by the slow progression of an injected contrast agent during diagnostic coronary angiography in the absence of significant stenosis. Although CSF is a common angiographic finding, the long-term outcomes and mortality rates are still unknown. This study aimed to investigate the underlying causes of mortality over a 10-year period in patients diagnosed with stable angina pectoris (SAP) and CSF. Materials and Methods: This study included patients with SAP who underwent coronary angiography from 1 January 2012 to 31 December 2012. All patients displayed CSF despite having angiographically normal coronary arteries. Hypertension (HT), diabetes mellitus (DM), hyperlipidaemia, medication compliance, comorbidities, and laboratory data were recorded at the time of angiography. Thrombolysis in myocardial infarction (TIMI) frame count (TFC) was calculated for each patient. The cardiovascular (CV) and non-CV causes of long-term mortality were assessed. Results: A total of 137 patients with CSF (93 males; mean age: 52.2 ± 9.36 years) were included in this study. Twenty-one patients (15.3%) died within 10 years of follow-up. Nine (7.2%) and 12 (9.4%) patients died of non-CV and CV causes, respectively. Total mortality in patients with CSF was associated with age, HT, discontinuation of medications, and high-density lipoprotein cholesterol (HDL-C) levels. The mean TFC was associated with CV mortality. Conclusion: Patients with CSF exhibited a notable increase in cardiovascular-related and overall mortality rates after 10 years of follow-up. HT, discontinuation of medications, HDL-C levels, and mean TFC were associated with mortality in patients with CSF.

This study aimed to systematically evaluate the efficacy and safety of different Chinese medicine injections combined with conventional western medicine for stable angina pectoris. PubMed, Cochrane Library, EMbase, Web of Science, CNKI, Wanfang, VIP, and SinoMed were searched to collect randomized controlled trial(RCT) of Chinese medicine injection combined with conventio-nal western medicine in the treatment of stable angina pectoris from the inception of the databases to July 8, 2022. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias of the included studies. Stata 15.1 was used for network Meta-analysis. A total of 52 RCTs were included, involving 4 828 patients treated by 9 Chinese medicine injections(Danhong Injection, Salvia Miltiorrhiza Polyphenol Hydrochloride Injection, Tanshinone Sodium â ¡_A Sulfonate Injection, Salvia Miltiorrhiza Ligustrazine Injection, Dazhu Hongjingtian Injection, Puerarin Injection, Safflower Yellow Pigment Injection, Shenmai Injection and Xuesaitong Injection). The network Meta-analysis showed that:(1)in terms of improving the efficacy of angina pectoris, the surface under the cumulative ranking curve(SUCRA) followed the order of conventional western medicine combined with Salvia Miltiorrhiza Ligustrazine Injection>Tanshinone Sodium â ¡_A Sulfonate Injection>Danhong Injection>Salvia Miltiorrhiza Polyphenol Hydrochloride Injection>Xuesaitong Injection>Shenmai Injection>Puerarin Injection>Safflower Yellow Pigment Injection>Dazhu Hongjingtian Injection;(2)in terms of improving the efficacy of electrocardiogram(ECG), SUCRA followed the order of conventional western medicine combined with Salvia Miltiorrhiza Ligustrazine Injection>Puerarin Injection>Danhong Injection>Salvia Miltiorrhiza Polyphenol Hydrochloride Injection>Shenmai Injection>Xuesaitong Injection>Safflower Yellow Pigment Injection>Tanshinone Sodium â ¡_A Sulfonate Injection>Dazhu Hongjingtian Injection;(3)in terms of increasing high-density lipoprotein cholesterol(HDL-C), SUCRA followed the order of conventional western medicine combined with Danhong Injection>Shenmai Injection>Safflower Yellow Pigment Injection>Xuesaitong Injection>Tanshinone Sodium â ¡_A Sulfonate Injection>Dazhu Hongjingtian Injection;(4)in terms of lowering low-density lipoprotein cholesterol(LDL-C), SUCRA followed the order of conventional western medicine combined with Safflower Yellow Pigment Injection>Danhong Injection>Shenmai Injection>Tanshinone Sodium â ¡_A Sulfonate Injection>Dazhu Hongjingtian Injection>Xuesaitong Injection;(5)in terms of safety, the overall adverse reactions of Chinese medicine injection combined with conventional western medicine were less than those of the control group. Current evidence indicated that Chinese medicine injection combined with conventional western medicine could improve the curative effect of stable angina pectoris with higher safety. Limited by the number and quality of included studies, the above conclusion needed to be verified by more high-quality studies.
