RESUMO

The increased use of reperfusion therapy in ST-segment-elevation myocardial infarction (STEMI) patients in the past decades is generally considered the main determinant of improved outcomes. The aim was to assess 20-year trends in profile, management, and one-year outcomes in STEMI patients in relation with use or non-use of reperfusion therapy (primary percutaneous coronary intervention (pPCI) or fibrinolysis). METHODS: We used data from 5 one-month French nationwide registries, conducted 5 years apart from 2005 to 2015, including 8579 STEMI patients (67% with and 33% without reperfusion therapy) admitted to cardiac intensive care units in France. RESULTS: Use of reperfusion therapy increased from 49% in 1995 to 82% in 2015, with a shift from fibrinolysis (37.5% to 6%) to pPCI (12% to 76%). Early use of evidence-based medications gradually increased over the period in both patients with and without reperfusion therapy, although it remained lower at all times in those without reperfusion therapy. One-year mortality decreased in patients with reperfusion therapy (from 11.9% in 1995 to 5.9% in 2010 and 2015, hazard ratio [HR] adjusted on baseline profile 0.40; 95% CI: 0.29-0.54, P < .001) and in those without reperfusion therapy (from 25.0% to 18.2% in 2010 and 8.1% in 2015, HR: 0.33; 95% CI: 0.24-0.47, P < .001). CONCLUSIONS: In STEMI patients, one-year mortality continues to decline, both related to increased use of reperfusion therapy and progress in overall patient management. In patients with reperfusion therapy, mortality has remained stable since 2010, while it has continued to decline in patients without reperfusion therapy.

RESUMO

In patients admitted for acute myocardial infarction, the communication and transition from specialists to primary care physicians is often delayed, and the information imparted to subsequent healthcare providers (HCPs) may be sub-optimal. A French group of cardiologists, lipidologists and diabetologists decided to establish a consensus to optimize the discharge letter after hospitalization for acute myocardial infarction. The aim is to improve both the timeframe and the quality of the content transmitted to subsequent HCPs, including information regarding baseline assessment, procedures during hospitalization, residual risk, discharge treatments, therapeutic targets and follow-up recommendations in compliance with European Society of Cardiology guidelines. A consensus was obtained regarding a template discharge letter, to be released within two days after patient's discharge, and containing the description of the patient's history, risk factors, acute management, risk assessment, discharge treatments and follow-up pathway. Specifically for post acute MI patients, tailored details are necessary regarding the antithrombotic regimen, lipid-lowering and anti-diabetic treatments, including therapeutic targets. Lastly, the follow-up pathway needs to be precisely mentioned in the discharge letter. Additional information such as technical descriptions, imaging, and quality indicators may be provided separately. A template for a standardized discharge letter based on 8 major headings could be useful for implementation in routine practice and help to improve the quality and timing of information transmission between HCPs after acute MI.

RESUMO

OBJECTIVES: Early endothelialization of drug-eluting stent (DES) is a major challenge to reduce the risk of stent thrombosis and the duration of dual-antiplatelet therapy (DAPT) in high bleeding-risk patients. The aim of the present study is to evaluate very early strut coverage with optical coherence tomography (OCT) of the Synergy stent (Boston Scientific) at 1 month in non-ST segment elevation acute coronary syndrome (NSTE-ACS) patients. METHODS: This substudy of the EARLY trial prospectively included NSTE-ACS patients treated with the Synergy DES. OCT analysis of the Synergy stent was performed during a staged PCI of additional lesions at 1 month. The primary endpoint was the percentage of covered struts assessed with OCT at 1 month. RESULTS: Twenty-four patients were included, with a mean stent length of 35.9 ± 10.1 mm per patient. The rate of covered struts was 78.5% out of 3839 struts analyzed. Nineteen patients (79.2%) had at least 70% of their struts covered. The average neointimal thickness was 0.0508 ± 0.016 mm. CONCLUSIONS: In NSTE-ACS patients undergoing culprit percutaneous coronary intervention with the Synergy stent, the rate of covered struts at 1 month was 78.5%. This rapid coverage is in line with the results of clinical trials demonstrating the safety of short-duration DAPT in selected patients who are at high bleeding risk and treated with new-generation DES options.

RESUMO

BACKGROUND: Conflicting information exists about whether sex differences modulate outcome in patients with coronary artery disease (CAD). Our aim was to analyze baseline characteristics, medical management, risk factor control, and long-term outcome according to gender in patients with stable CAD. METHODS: We analyzed data from the contemporary multicenter CORONOR registry, which included 4184 consecutive outpatients with stable CAD. Follow-up was performed at 5 years with adjudication of clinical events. RESULTS: There were 3252 (77.7%) men and 932 (22.3%) women. Women were older than men, more likely to have hypertension, and less likely to smoke. They had more frequent angina but less frequent multivessel CAD. Evidence-based medications were widely used with only few differences according to gender. Women had a poorer control of cardiovascular risk with higher systolic blood pressure and LDL-cholesterol. The composite endpoint - cardiovascular death, myocardial infarction, or ischemic stroke - occurred in 536 patients. When adjusted for baseline characteristics, five-year outcomes were similar for women and men for the composite endpoint (Hazard ratio [95% confidence interval]: 1.03 [0.81-1.31], p=0.817). CONCLUSIONS: In contemporary practice, women with stable CAD had a poorer control of cardiovascular risk. However, at 5-year follow-up, cardiovascular outcomes were similar for both genders.

RESUMO

BACKGROUND: We lack recent data on the incidence, correlates, and prognosis associated with heart failure (HF) development in patients with stable coronary artery disease (CAD). Here, we analyzed HF development in a contemporary population of outpatients with stable CAD. METHODS AND RESULTS: Of 4184 unselected outpatients with stable CAD (ie, myocardial infarction [MI] and/or coronary revascularization >1 year earlier) included in the multicenter CORONOR registry, we identified 3871 patients with no history of hospitalization for HF at inclusion and followed 3785 (98%) of them for 5 years. During follow-up, 211 patients were hospitalized for HF (5-year cumulative incidence 5.7%) and 163 patients had incident MIs. Independent predictors of hospitalization for HF were older age, lower left ventricular ejection fraction (LVEF), atrial fibrillation, higher body mass index, diabetes mellitus, history of hypertension, angina at inclusion, and multivessel CAD. Most hospitalizations for HF (62.6%) occurred in patients with LVEF ≥50% at inclusion, and most (92.4%) were not preceded by an incident MI. Hospitalization for HF was a powerful predictor of mortality (adjusted hazard ratio 5.97, 95% confidence interval 4.55-7.83; P < .0001). After hospitalization for HF, mortality rates were similar in patients with LVEFs ≥50% and <50% at hospitalization. CONCLUSIONS: Outpatients with stable CAD were frequently hospitalized for HF, and HF was associated with high mortality. Most HF hospitalizations were associated with preserved LVEF at inclusion and were not preceded by an incident MI.

RESUMO

BACKGROUND: The clinical benefit of anti-platelet agents in patients with chronic kidney disease (CKD) is uncertain. In addition, the risk-benefit ratio of potent oral P2Y12-adenosine diphosphate (ADP) receptor antagonists (PPAs), namely, prasugrel and ticagrelor, compared with clopidogrel in CKD patients suffering from acute coronary syndrome (ACS) remains unknown. OBJECTIVE: We performed a meta-analysis of all studies comparing the clinical outcomes of PPA and clopidogrel therapy in CKD patients suffering from ACS. METHODS: We searched PubMed, the Cochrane library, Google Scholar, Clinical trial.org and the abstracts of international cardiology congresses from April 2000 to October 2017. Clinical studies comparing PPA with clopidogrel in ACS patients with CKD were selected. Our literature research identified five studies which were included in the meta-analysis. The primary endpoint was a composite of major adverse cardiovascular events (MACEs) at the latest follow-up available. Secondary endpoint included bleedings. RESULTS: We included data from three sub-group analysis of randomized clinical trials and two prospective observational studies (n = 31,234). Overall, PPAs were associated with lower rates of major cardiovascular events, with a pooled hazard ratio (pHR) of 0.88 (95% confidence interval [CI]: 0.79-0.99; p = 0.03), without increased bleedings (pHR = 1.10) (95% CI: 0.95-1.27; p = 0.18). In a sensitivity analysis restricted to studies enrolling invasively managed patients, the benefit of PPA on MACE was maintained (pHR = 0.85) (95% CI: 0.77-0.93; p < 0.001), including a reduction in mortality (pHR = 0.82) (95% CI: 0.7-0.96; p = 0.016). CONCLUSION: Compared with clopidogrel, PPAs were associated with a reduced rate of MACE without increased bleedings in CKD patients with ACS. Among invasively managed patients, this benefit from PPA included a reduction in mortality.

RESUMO

BACKGROUND: Coronary artery disease (CAD) is the leading cause of systolic heart failure (HF). Cardiac magnetic resonance imaging (CMR) is a non-invasive technique that detects a myocardial infarction scar as subendocardial or transmural late gadolinium enhancement (st-LGE). AIM: We sought to evaluate whether a lack of st-LGE could rule out CAD in new-onset systolic HF of unknown aetiology. METHODS: We included 232 consecutive patients with new-onset HF and left ventricular ejection fraction ≤35% who underwent both coronary angiography and CMR to assess HF aetiology. CAD was defined as the presence of coronary artery stenosis≥50% on a coronary angiogram. We assessed sensitivity, specificity, and positive and negative likelihood ratios (PLR and NLR) of the presence of st-LGE to detect underlying CAD. A complementary meta-analysis of 11 studies (including ours) was also performed. RESULTS: In our study, 49 (21.1%) patients had CAD. The sensitivity and specificity of the presence of st-LGE to detect CAD were 69 and 92%, respectively. PLR and NLR were 8.47 and 0.33, respectively. In the meta-analysis, 1227 patients were included, and the prevalence of CAD ranged from 19.2 to 68.3%. Sensitivity, specificity, PLR and NLR were 87% (95% confidence interval [CI] 0.80-0.92), 93% (95% CI 0.89-0.96), 12.91 (95% CI 7.70-21.64) and 0.14 (95% CI 0.09-0.22), respectively. Altogether, 55 patients presented CAD with no st-LGE; inversely, 75 patients presented st-LGE with no CAD. CONCLUSION: With a CMR specificity of 93%, the absence of st-LGE rules out significant underlying CAD in patients with systolic HF of unknown aetiology in most cases.

RESUMO

BACKGROUND: Left ventricular remodeling (LVR) after myocardial infarction is associated with an increased risk of heart failure and death. In spite of a modern therapeutic approach, LVR remains relatively frequent and difficult to predict in clinical practice. Our aim was to identify new biomarkers of LVR and understand their involvement in its development. METHODS AND RESULTS: Proteomic analysis of plasma from the REVE-2 study (Remodelage Ventriculaire)-a study dedicated to the analysis of LVR which included 246 patients after a first anterior myocardial infarction-identified increased plasma levels of CLU (clusterin) in patients with high LVR. We used a rat model of myocardial infarction to analyze CLU expression in the LV and found a significant increase that was correlated with LVR parameters. We found increased CLU expression and secretion in primary cultures of rat neonate cardiomyocytes hypertrophied by isoproterenol. Silencing of CLU in hypertrophied neonate cardiomyocytes induced a significant decrease in cell size, ANP (atrial natriuretic peptide), and BNP (B-type natriuretic peptide) expression, associated with a decreased ERK (extracellular signal-regulated kinase) 1/2 activity, suggesting a prohypertrophic role of CLU. We then confirmed a significant increase of both intracellular p-CLU (precursor form of CLU) and m-CLU (mature form of CLU) in failing human hearts. Finally, the circulating levels of CLU (secreted form) were increased in patients with chronic heart failure who died from cardiovascular cause during a 3-year follow-up (n=99) compared with survivors (n=99). CONCLUSIONS: Our results show for the first time that plasma CLU levels are associated with LVR post-myocardial infarction, have in part a cardiac origin, and are a predictor of early death in heart failure patients.

RESUMO

AIMS: The aim of the study was to assess the outcomes of balloon aortic valvuloplasty (BAV) as a rescue therapy in patients with cardiogenic shock (CS) related to severe aortic stenosis (AS). METHODS AND RESULTS: Forty-four consecutive patients, n=31 with hypotensive CS (HCS) and n=13 with non-hypotensive CS (NHCS) due to acutely decompensated severe AS, from two centres were treated with urgent BAV. The composite primary endpoint was mortality or recurrent CS at one-year follow-up. These patients (77.3±8.1 years old; 75% male) had a mean EuroSCORE II of 41.6±13.7%. One-month mortality was 47%. Twelve patients (27%) had either a staged TAVR (n=10) or surgical aortic valve replacement (SAVR) (n=2) with a median delay of 79 days after BAV: n=6 (19%) in the HCS subgroup and n=6 (46%) in the NHCS population (p=0.06). At one year, the rate of composite all-cause death or recurrent CS was 75% and significantly higher in the HCS subgroup (83% vs. 53%; p=0.03). Overall one-year mortality was 70% (n=31) with a trend for a better prognosis in NHCS patients (54% vs. 77%; p=0.09). Univariate predictive factors of the primary endpoint included preoperative dose of dobutamine >5 microg/kg/min (100% vs. 57%; p=0.001) and delayed BAV >48 hrs (90% vs. 59%; p=0.01). CONCLUSIONS: Despite the initial success of urgent BAV, morbidity and mortality of CS related to severe AS remain high and directly related to the time of the valvuloplasty. Performing BAV before or within 48 hours of starting inotropic agents appears to be key to survival.

RESUMO

BACKGROUND: The main risk factor for bleeding in patients with continuous-flow mechanical circulatory support (CF-MCS) is the acquired von Willebrand factor (VWF) defect related to the high shear-stress forces developed by these devices. Although a higher bleeding rate has been reported in CF-MCS recipients who had reduced pulsatility, the relation between pulsatility and the VWF defect has never been studied. OBJECTIVES: The purpose of this study was to investigate the relation between pulsatility and VWF under CF-MCS. METHODS: We assessed the effect of 2 CF-MCS on VWF multimer degradation in a mock circulatory loop (model 1). Using these devices, we investigated in a dose-effect model (model 2) 3 levels of pulsatility in 3 groups of swine. In a cross-over model (model 3), we studied the effects of sequential changes of pulsatility on VWF. We reported the evolution of VWF multimerization in a patient undergoing serial CF-MCS and/or pulsatile-MCS. RESULTS: We demonstrated the proteolytic degradation of VWF multimers by high shear CF-MCS in a circulatory loop without pulsatility. We observed both in swine models and in a patient that the magnitude of the VWF degradation is modulated by the pulsatility level in the high shear-stress level condition, and that the restoration of pulsatility is a trigger for the endothelial release of VWF. CONCLUSIONS: We demonstrated that the VWF defect reflects the balance between degradation induced by the shear stress and the endothelial release of new VWF triggered by the pulsatility. This modulation of VWF levels could explain the relationship between pulsatility and bleeding observed in CF-MCS recipients. Preservation of pulsatility may be a new target to improve clinical outcomes of patients.

RESUMO

OBJECTIVES: The authors sought to describe the incidence, determinants, and outcome of elective coronary revascularization (ECR) in patients with stable coronary artery disease (CAD). BACKGROUND: Observational data are lacking regarding the practice of ECR in patients with stable CAD receiving modern secondary prevention. METHODS: The authors analyzed coronary revascularization procedures performed during a 5-year follow-up in 4,094 stable CAD outpatients included in the prospective multicenter CORONOR (Suivi d'une cohorte de patients COROnariens stables en région NORd-Pas-de-Calais) registry. RESULTS: Secondary prevention medications were widely prescribed at inclusion (antiplatelet agents 96.4%, statins 92.2%, renin-angiotensin system antagonists 81.8%). A total of 481 patients underwent ≥1 coronary revascularization procedure (5-year cumulative incidences of 3.6% [0.7% per year] for acute revascularizations and 8.9% [1.8% per year] for ECR); there were 677 deaths during the same period. Seven baseline variables were independently associated with ECR: prior coronary stent implantation (p < 0.0001), absence of prior myocardial infarction (p < 0.0001), higher low-density lipoprotein cholesterol (p < 0.0001), lower age (p < 0.0001), multivessel CAD (p = 0.003), diabetes mellitus (p = 0.005), and absence of treatment with renin-angiotensin system antagonists (p = 0.020). Main indications for ECR were angina associated with a positive stress test (31%), silent ischemia (31%), and angina alone (25%). The use of ECR had no impact on the subsequent risk of death, myocardial infarction, or ischemic stroke (hazard ratio: 1.04; 95% confidence interval: 0.76 to 1.41). CONCLUSIONS: These real-life data show that ECR is performed at a rate of 1.8% per year in stable CAD patients widely treated by secondary medical prevention. ECR procedures performed in patients without noninvasive stress tests are not rare. Having an ECR was not associated with the risk of ischemic adverse events.

RESUMO

BACKGROUND: The relation between diabetes mellitus, glycemic control, and ischemic and bleeding events is poorly described in outpatients with stable coronary artery disease receiving modern secondary prevention. METHODS AND RESULTS: The multicenter CORONOR (Suivi d'une cohorte de patients Coronariens stables en région Nord-pas-de-Calais) registry enrolled 4184 outpatients with stable coronary artery disease, including 1297 patients (31%) with diabetes mellitus. A recent glycosylated hemoglobin (HbA1c) was available for 1146 diabetic patients, and 48% had HbA1c ≥7%. We analyzed 5-year ischemic (cardiovascular death, myocardial infarction, and stroke) and bleeding (Bleeding Academic Research Consortium ≥3) outcomes, according to diabetic status and glycemic control. When compared with nondiabetic patients, the ischemic risk was higher in diabetic patients with HbA1c ≥7% (hazard ratio [HR], 1.57; 95% confidence interval [CI], 1.25-1.93) but not in diabetic patients with HbA1c <7% (HR, 1.06; 95% CI, 0.83-1.36). Diabetic patients with HbA1c ≥7% were at higher risk than diabetic patients with HbA1c <7% (HR, 1.47; 95% CI, 1.09-1.98). When compared with nondiabetic patients, the bleeding risk was higher in diabetic patients, with HbA1c <7% (HR, 1.66; 95% CI, 1.04-2.67) and in those with HbA1c ≥7% (HR, 1.75; 95% CI, 1.07-2.86). No difference in bleeding risk was observed between diabetic patients with HbA1c ≥7% versus those with HbA1c <7%. Similar results were obtained when adjusted for baseline characteristics. CONCLUSIONS: The 5-year increased risk of ischemic events in patients with stable coronary artery disease with diabetes mellitus was restricted to those with HbA1c ≥7%. By contrast, the increase in bleeding risk associated with diabetes mellitus was observed in patients with HbA1c ≥7% and in patients with HbA1c <7%. The level of HbA1c should be taken into account for future research and may help physicians to manage prolonged antithrombotic therapies in this high-risk subgroup.

RESUMO

BACKGROUND: Cardiogenic shock (CS) complicating acute myocardial infarction (AMI) occurs more frequently in women, but little is known about its potential specificities according to sex. AIMS: To analyse the incidence, management and 1-year mortality of CS according to sex using the FAST-MI programme. METHODS: The FAST-MI programme consists of four nationwide French surveys carried out 5 years apart from 1995 to 2010, including consecutive patients with AMI over a 1-month period, and with a 1-year follow-up. RESULTS: Among the 10,610 patients included in the surveys, the incidence of CS was 4.8% in men and 8.2% in women (P<0.001). Absolute incidence of CS decreased from 1995 to 2010 in both sexes. Mean age in patients with CS tended to decrease in men (from 72±12 to 69±13 years) and to increase in women (from 78±10 to 80±9 years). One-year mortality decreased significantly in men (from 70% in 1995 to 48% in 2010) and in women (from 81% to 54%). Using Cox multivariable analysis, female sex was not an independent correlate of 1-year mortality [hazard ratio (HR): 0.98, 95% confidence interval (CI): 0.78-1.22]. Early use of percutaneous coronary intervention was, however, an independent predictor of 1-year survival in women (HR: 0.55, 95% CI: 0.37-0.81), but showed only a non-significant trend in men (HR: 0.85, 95% CI: 0.61-1.19). CONCLUSIONS: The incidence of CS-AMI has decreased in both men and women, but remains higher in women. One-year mortality has significantly decreased for both men and women, and the role of early percutaneous coronary intervention as a potential mediator of decreased mortality seems greater in women than in men.

RESUMO

According to recent literature, pretreatment with a P2Y12 ADP receptor antagonist before coronary angiography appears no longer suitable in non-ST-segment elevation acute coronary syndrome (NSTE-ACS) due to an unfavorable risk-benefit ratio. Optimal delay of the invasive strategy in this specific context is unknown. We hypothesize that without P2Y12 ADP receptor antagonist pretreatment, a very early invasive strategy may be beneficial. The EARLY trial (Early or Delayed Revascularization for Intermediate- and High-Risk Non-ST-Segment Elevation Acute Coronary Syndromes?) is a prospective, multicenter, randomized, controlled, open-label, 2-parallel-group study that plans to enroll 740 patients. Patients are eligible if the diagnosis of intermediate- or high-risk NSTE-ACS is made and an invasive strategy intended. Patients are randomized in a 1:1 ratio. In the control group, a delayed strategy is adopted, with the coronary angiography taking place between 12 and 72 hours after randomization. In the experimental group, a very early invasive strategy is performed within 2 hours. A loading dose of a P2Y12 ADP receptor antagonist is given at the time of intervention in both groups. Recruitment began in September 2016 (n = 558 patients as of October 2017). The primary endpoint is the composite of cardiovascular death and recurrent ischemic events at 1 month. The EARLY trial aims to demonstrate the superiority of a very early invasive strategy compared with a delayed strategy in intermediate- and high-risk NSTE-ACS patients managed without P2Y12 ADP receptor antagonist pretreatment.

RESUMO

Cardiogenic Shock (CS) is a major challenge in current cardiology. Over the last decade, cardiogenic shock mortality has decreased somewhat, but it still remains high, particularly when associated with ischaemic heart disease. The challenges are numerous and include prevention, accurate diagnosis, prompt management and effective therapies to support a failing heart and prevent multi-organ failure. Despite improvements in the care of Acute Coronary Syndrome (ACS), it remains the most common cause of CS. In addition to existing medical therapy, mechanical circulatory support has been proposed for the management of ventricular failure. The intra-aortic balloon pump was amongst the first widely used percutaneous mechanical support devices, and more recently, systems providing a higher level of support have been developed. Although the evidence supporting their use is limited, they have the potential to significantly reduce CS-associated mortality. In this narrative review, we summarize the available evidence and discuss the future directions regarding percutaneous mechanical circulatory support in patients with left ventricular dysfunction and CS complicating ACS.

RESUMO

BACKGROUND: Low-density lipoprotein cholesterol (LDL-C) reduction is an integral part of the management of patients with coronary artery disease (CAD). AIMS: To assess attainment of LDL-C goals during long-term treatment of patients with stable CAD, and to determine predictors of goal attainment and the prognostic impact of reaching LDL-C<70mg/dL (1.8mmol/L) in a real-life setting. METHODS: Data were obtained for 4080 outpatients with stable CAD included in the multicentre CORONOR study. Five-year follow-up was achieved for 3991 (97.8%) patients. RESULTS: At inclusion, a recent (<1 year) measurement of LDL-C was available in 3757 (92.1%) patients. LDL-C<70mg/dL was reached by 885 (23.6%) patients. Independent predictors of LDL-C<70mg/dL were diabetes mellitus, statin treatment, treatment with renin-angiotensin system inhibitors, previous myocardial infarction and short time since last coronary event. The adjusted hazard ratio (HR) for the composite endpoint (cardiovascular death, myocardial infarction, ischemic stroke or coronary revascularization) during the 5-year follow-up was 1.31 (95% confidence interval [CI]: 1.09-1.58; P=0.004) for LDL-C≥70mg/dL versus<70mg/dL. When compared with patients with LDL-C<70mg/dL, the adjusted HRs for LDL-C 70-99mg/dL and ≥100mg/dL (2.6mmol/L) were 1.27 (95% CI: 1.05-1.55; P=0.016) and 1.38 (95% CI: 1.12-1.70; P=0.003), respectively. When LDL-C was used as a continuous variable, the adjusted HRs for increases of 10mg/dL (0.3mmol/L) and 1mmol/L were 1.05 (95% CI: 1.03-1.08) and 1.21 (95% CI: 1.10-1.33), respectively. CONCLUSIONS: In this observational study, only a minority of stable CAD patients had LDL-C<70mg/dL. The patients who reached their LDL-C goal had the lowest risk of cardiovascular events.
