Effect of Heart Failure on Long-Term Clinical Outcomes After Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting in Patients With Severe Coronary Artery Disease

High-risk percutaneous coronary intervention in patients with reduced left ventricular ejection fraction deemed not suitable for surgical revascularisation. A clinical consensus statement from the European Association of Percutaneous Cardiovascular Interventions (EAPCI) in collaboration with the ESC Working Group on Cardiovascular Surgery

This clinical consensus statement of the European Association of Percutaneous Cardiovascular Interventions was developed in association with the European Society of Cardiology Working Group on Cardiovascular Surgery. It aims to define procedural and contemporary technical requirements that may improve the efficacy and safety of percutaneous coronary intervention (PCI), both in the acute phase and at long-term follow-up, in a high-risk cohort of patients on optimal medical therapy when clinical and anatomical high-risk criteria are present that entail unacceptable surgical risks, precluding the feasibility of coronary artery bypass grafting (CABG). This document pertains to patients with surgical contraindication according to the Heart Team, in whom medical therapy has failed (e.g., residual symptoms), and for whom the Heart Team estimates that revascularisation may have a prognostic benefit (e.g., left main, last remaining vessel, multivessel disease with large areas of ischaemia); however, there is a lack of data regarding the size of this patient population. This document aims to guide interventional cardiologists on how to proceed with PCI in such high-risk patients with reduced left ventricular ejection fraction after the decision of the Heart Team is made that CABG - which overall is the guideline-recommended option for revascularisation in these patients - is not an option and that PCI may be beneficial for the patient. Importantly, when a high-risk PCI is planned, a multidisciplinary decision by interventional cardiologists, cardiac surgeons, anaesthetists and non-invasive physicians with expertise in heart failure management and intensive care should be agreed upon after careful consideration of the possible undesirable consequences of PCI, including futility, similar to the approach for structural interventions.

Temporal Trend in Revascularization for Patients With Ischemic Cardiomyopathy and Multivessel Coronary Artery Disease

BACKGROUND

Current guidelines recommend revascularization in patients with ischemic cardiomyopathy (ICM). However, there is limited information about the trends and outcomes of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in ischemic cardiomyopathy patients with multivessel coronary artery disease.

METHODS AND RESULTS

Using New Jersey state mandatory registries, 8083 patients with ischemic cardiomyopathy with CABG or PCI revascularization for multivessel coronary artery disease from 2007 to 2018 were included in the analysis. Joinpoint regression and multivariable logistic regression analyses were performed to assess the annual percentage change in trends and predictors of the 30-day mortality rate, respectively. A decline in CABG procedures was observed from 2007 to 2011 (annual percentage change, -11.5%; P=0.003), followed by stabilization. The PCI trend remained unchanged from 2007 to 2010 and then increased significantly (annual percentage change, 3.2%; P=0.02). In the subsample of patients with proximal left anterior descending artery plus circumflex and right coronary artery, CABG was a predominant procedure until 2011, and the proportion of both procedures did not differ thereafter. In the subsample of patients with left anterior descending artery and any other artery stenosis, PCI remained dominant from 2007 to 2018, while in patients with left main and any other artery stenosis, CABG remained dominant from 2007 to 2018 (P<0.001). The 30-day risk-adjusted mortality rate was higher after PCI versus CABG for each year, but after adjustment for completeness of revascularization, there was no difference between groups.

CONCLUSIONS

The patterns of revascularization procedures for patients with ischemic cardiomyopathy with multivessel coronary artery disease have changed over the years, as evidenced by the changes in CABG and PCI trends. CABG and PCI had comparable 30-day risk-adjusted mortality risks.

Biomarker prognostication across Universal Definition of Heart Failure stages

AIM

The Universal Definition of Heart Failure (UDHF) provides a framework for staging risk for HF events. It is not clear whether prognostic biomarkers have different meaning across UDHF stages. We sought to evaluate performance of biomarkers to predict HF events among high-risk patients undergoing coronary and/or peripheral angiography categorized into UDHF stages.

METHODS

One thousand two hundred thirty-five individuals underwent coronary and/or peripheral angiography were enrolled. Study participants were categorized into UDHF Stage A (at risk), Stage B (pre-HF), and Stage C or D (HF, including end stage) and grouped into Stage A/B and C/D. Biomarkers and clinical variables were used to develop prognostic models. Other measures examined included total HF hospitalizations.

RESULTS

Over a median of 3.67 years of follow-up, 155 cardiovascular (CV) deaths occurred, and 299 patients were hospitalized with acute HF. In patients with Stage A/B, galectin-3 (HR = 1.52, P = 0.03), endothelin-1 (HR = 2.16, P = 0.001), and N-terminal pro-B-type natriuretic peptide (NT-proBNP; HR = 1.43, P < 0.001) were associated with incident CV death/HF hospitalization. In Stage C/D, NT-proBNP (HR = 1.26, P = 0.006), soluble urokinase-type plasminogen activator receptor (suPAR; HR = 1.57, P = 0.007) and high-sensitivity C-reactive protein (hs-CRP; HR = 1.15, P = 0.01) were associated with these outcomes. Higher biomarker concentrations were associated with greater total burden of HF events in Stages A/B and C/D.

CONCLUSIONS

Among higher risk individuals undergoing angiographic procedures, different biomarkers improve risk stratification in different UDHF stages of HF. More precise prognostication may offer a window of opportunity to initiate targeted preventive measures.

Prognostic Value of High-Sensitivity C-Reactive Protein in In-Stent Restenosis: A Meta-Analysis of Clinical Trials

Background: A risk assessment of in-stent restenosis (ISR) patients is critical for providing adequate treatment. Nevertheless, the prognostic value of high-sensitivity CRP (hs-CRP) levels on ISR has not been consistently demonstrated in clinical studies. In the current meta-analysis, we aim to assess the predictive role of hs-CRP in patients treated with stenting. Methods: We searched PubMed, Web of Science, Embase, and the Cochrane Registry through May 2022. We selected random control trials that compared the effects of different interventions, and that revealed the effects of hs-CRP. Two reviewers independently screened the articles, extracted the data, and assessed the quality of the studies according to the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). The data were pooled using a random-effects meta-analysis. Results: Nine articles were included in the meta-analysis. A total of 1.049 patients received stent implantation, and 185 ISR events were recorded during the 1–12-month follow-up period. Baseline hs-CRP levels were not associated with the prediction of ISR among patients receiving stent implantation. The OR of hs-CRP for ISR was 1.81 (0.92–2.69). In the subgroup analysis, 6–12-month hs-CRP levels, diabetes mellitus (DM), and age ≥60(years)were associated with a higher risk of ISR. Conclusions: This meta-analysis shows that higher levels of baseline hs-CRP are not associated with an increased risk of ISR in stented patients. However, an increased risk of ISR was associated with hs-CRP levels at 6 to 12 months of follow-up, which is higher in studies with diabetes mellitus patients and the elderly.

Triglyceride-glucose index in the prediction of major adverse cardiovascular events in patients with type 2 diabetes mellitus after coronary artery bypass surgery: A retrospective cohort study

BACKGROUND

Insulin resistance (IR) is a significant risk factor for cardiometabolic diseases and a defining feature of type 2 diabetes mellitus (T2DM). This study aimed to examine the potential value of triglyceride-glucose (TyG) index as a predictor of prognosis in coronary heart disease (CHD) patients with T2DM after coronary artery bypass grafting (CABG) surgery and to facilitate the identification of those at high risk of major adverse cardiovascular events (MACEs) for closer monitoring or possible early intervention.

METHODS

This study enrolled 386 T2DM patients who underwent CABG surgery at Nanjing Drum Tower Hospital. Patients were separated into two groups according to the median preoperative TyG Index. The Kaplan-Meier plot was used to compare the rate of MACEs-free survival in T2DM patients after CABG. The independent risk factors for the occurrence of MACEs were investigated using multivariate analysis. Nomogram was used to depict the predictive model.

RESULTS

Significantly more MACEs occurred in individuals with higher medians of the TyG index (65 (33.7%) vs. 39 (20.2%), p=0.003). TyG index [hazard ratio (HR) 12.926], LVEF [hazard ratio (HR) 0.916], and NYHA functional class III/IV [hazard ratio (HR) 4.331] were identified as independent predictors of MACEs incidence in post-CABG T2DM patients by multivariate analysis. The area under the curve (AUC) for predicting MACEs using the TyG index was 0.89 at five years. Combining the TyG index, LVEF, and NYHA functional class III/IV to build a novel risk assessment model for postoperative MACEs, the AUC climbed to 0.93 at five years. With AUCs, the nomogram comprised of the TyG index, LVEF, and NYHA functional class III/IV demonstrated strong specificity in the training and test sets.

CONCLUSIONS

The incidence of MACEs is high among post-CABG T2DM patients with a high TyG index. TyG index improves the diagnostic accuracy of MACEs, especially at long-term follow-up. A high TyG index may serve as an early warning signal for individuals to undertake lifestyle adjustments that can reduce the progression or incidence of MACEs.
