Current Strategies to Guide the Antiplatelet Therapy in Acute Coronary Syndromes.

The role of antiplatelet therapy in patients with acute coronary syndromes is a moving target with considerable novelty in the last few years. The pathophysiological basis of the treatment depends on platelet biology and physiology, and the interplay between these aspects and clinical practice must guide the physician in determining the best therapeutic options for patients with acute coronary syndromes. In the present narrative review, we discuss the latest novelties in the antiplatelet therapy of patients with acute coronary syndromes. We start with a description of platelet biology and the role of the main platelet signal pathways involved in platelet aggregation during an acute coronary syndrome. Then, we present the latest evidence on the evaluation of platelet function, focusing on the strengths and weaknesses of each platelet's function test. We continue our review by describing the role of aspirin and P2Y12 inhibitors in the treatment of acute coronary syndromes, critically appraising the available evidence from clinical trials, and providing current international guidelines and recommendations. Finally, we describe alternative therapeutic regimens to standard dual antiplatelet therapy, in particular for patients at high bleeding risk. The aim of our review is to give a comprehensive representation of current data on antiplatelet therapy in patients with acute coronary syndromes that could be useful both for clinicians and basic science researchers to be up-to-date on this complex topic.

Acute coronary syndrome in very elderly patients-a real-world experience.

Very elderly population constitutes an increasingly larger proportion of patients admitted for acute coronary syndromes (ACS). Notably, age represents both a proxy of frailty and an exclusion criterion in clinical randomized trials, which probably contributes to lack of data and undertreatment of real-world elderly patients. The aim of the study is to describe patterns of treatment and outcome of very elderly patients with ACS. All consecutive patients aged ≥ 80 years old (yo) admitted between January 2017 and December 2019 with ACS were included. The primary endpoint was in-hospital occurrence of major adverse cardiovascular events (MACE), defined as the composite of cardiovascular death, new onset cardiogenic shock, definite/probable stent thrombosis, and ischemic stroke. The secondary endpoints were in-hospital incidence of Thrombolysis in Myocardial Infarction (TIMI) major/minor bleedings, contrast-induced nephropathy (CIN), six-month all-cause mortality, and unplanned readmission. One hundred ninety-three patients (mean age 84.1 ± 3.5 yo, 46% females) were included, of whom 86 (44.6%), 79 (40.9%), and 28 (14.5%) presented with ST elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI), and unstable angina (UA), respectively. The vast majority of patients received an invasive strategy, with 92.7% undergoing coronary angiography and 84.4% to percutaneous coronary intervention (PCI). Aspirin was administered to 180 (93.3%) patients, clopidogrel to 89 (46.1%) patients, and ticagrelor to 85 (44%) patients. In-hospital MACE occurred in 29 patients (15.0%), whereas 3 (1.6%) and 12 patients (7.2%) experienced in-hospital TIMI major and TIMI minor bleeding, respectively. Of the overall population, 177 (91.7%) were discharged alive. After discharge, 11 patients (6.2%) died of all-cause death, whereas 42 patients (23.7%) required a new hospitalization within six months. Invasive strategy of ACS in elderly patients seems safe and effective. Six-month new hospitalization appears inevitably related to age.

Clinical Outcomes of Percutaneous Left-Atrial Appendage Occlusion with Conscious Sedation without an Anesthesiologist on Site: Results from a Multicenter Study.

Background and Objectives: Percutaneous left-atrial appendage (LAA) occlusion is an important therapeutic option for preventing cardioembolic stroke in patients with non-valvular atrial fibrillation (AF) at high risk of thromboembolic events and with contraindications for oral anticoagulation (OAC). It is usually performed with transesophageal echocardiography (TOE) guidance under general anesthesia (GA). In this retrospective study, we present a multicenter experience of LAA occlusion performed with conscious sedation (CS) without an anesthesiologist on site. Materials and Methods: All the patients on the waiting list for LAA occlusion procedure at Infermi Hospital, Rivoli, and San Luigi Gonzaga University Hospital, Orbassano, from October 2018 to October 2022 were analyzed. All the procedures were performed with a Watchman/FLX LAA closure device under TOE and fluoroscopic guidance without an anesthesiologist on site. CS was performed with a combination of midazolam and fentanyl as needed. Results: One-hundred fifteen patients were included (age 76.4 ± 7.6 years, median CHA2DS2Vasc 4.4 ± 1.4). CS was performed using midazolam (mean dose 5.9 ± 2.1 mg), adding fentanyl for thirty-nine (33.9%) patients in case of poor tolerance for the procedure despite midazolam. The acute procedural success rate was 99.1%. We observed seven acute severe complications. No patients needed anesthesiological assistance during the procedure, and no cases of respiratory failure necessitating ventilation were reported. In a follow-up after 10 ± 9 months, one case of stroke (0.9%) and one case (0.9%) of transient ischemic attack (TIA) occurred. Conclusions: LAA occlusion performed under CS and without the presence of an anesthesiologist on site appears to be safe and effective. It can be an attractive alternative to general anesthesia (GA), as fewer resources are required.

Left Ventricular Thrombus Management After Acute Myocardial Infarction in Clinical Practice: Results from LEVITATION Survey and Narrative Review.

PURPOSE: Left ventricular thrombus (LVT) after ST-elevation myocardial infarction still presents diagnostic and therapeutic challenges. The LEVITATION survey was designed to take a picture of LVT management in current clinical practice. METHODS: The survey covered diagnostic, therapeutic, and prophylactic issues and was completed by 104 European cardiac centers. Most of them (59%) were university or tertiary centers. RESULTS: The survey showed anterior apical a-/dyskinesia, large MI, spontaneous echo-contrast, late presentation with delayed PCI, and TIMI flow 0-1 as the most important perceived risk factors for LVT formation. Serial ultrasound imaging is the most used tool to diagnose LVT (88% of the centers), with contrast-enhanced ultrasound and cardiac MR performed in case of poor apex visualization or spontaneous echo-contrast. One third (34%) of the centers uses prophylactic anticoagulation to prevent LVT formation. In the presence of LVT, low molecular weight heparin is the most used in-hospital therapy. At discharge, vitamin K antagonist and direct oral anticoagulants are used in 67 and 32% of the cases, respectively. Triple antithrombotic therapy with aspirin plus clopidogrel and VKA is the most used strategy at discharge (55%), whereas a single antiplatelet therapy is preferred only in the case of moderate-to-high risk of bleeding. To assess LVT total regression, half of the centers use contrast-enhanced ultrasound and/or cardiac-MR. The duration of anticoagulation is usually 3-6 months (55%), with long-term prolongation in case of LVT persistence or recurrence. CONCLUSION: The survey has depicted for the first time the current real-world management of this neglected topic and has highlighted several grey zones that are still present and not supported by evidence.

Epilepsy and syncope - A case report and narrative review of arrhythmias connected to temporal lobe epilepsy.

We present the case of a 28-years-old male presenting to the Emergency Department for relapsing episodes of "déjà vu" and syncope. After a diagnostic workup by a multidisciplinary team, the simultaneous EEG and ECG monitoring showed an asystole associated with EEG anomalies in right fronto-temporal region of the brain. The brain MRI revealed an ischemic lesion concordant with EEG anomalies. In the suspicion of an ictal asystole, we decided not to implant a permanent pacemaker as the first line therapy but started a targeted anti-epileptic therapy. No more syncopal episodes nor dysrhythmias occurred during recovery and almost two years follow-up.

Antiplatelet therapy in patients with conservatively managed spontaneous coronary artery dissection from the multicentre DISCO registry.

AIMS: The role of antiplatelet therapy in patients with spontaneous coronary artery dissection (SCAD) undergoing initial conservative management is still a matter of debate, with theoretical arguments in favour and against its use. The aims of this article are to assess the use of antiplatelet drugs in medically treated SCAD patients and to investigate the relationship between single (SAPT) and dual (DAPT) antiplatelet regimens and 1-year patient outcomes. METHODS AND RESULTS: We investigated the 1-year outcome of patients with SCAD managed with initial conservative treatment included in the DIssezioni Spontanee COronariche (DISCO) multicentre international registry. Patients were divided into two groups according to SAPT or DAPT prescription. Primary endpoint was 12-month incidence of major adverse cardiovascular events (MACE) defined as the composite of all-cause death, non-fatal myocardial infarction (MI), and any unplanned percutaneous coronary intervention (PCI). Out of 314 patients included in the DISCO registry, we investigated 199 patients in whom SCAD was managed conservatively. Most patients were female (89%), presented with acute coronary syndrome (92%) and mean age was 52.3 ± 9.3 years. Sixty-seven (33.7%) were given SAPT whereas 132 (66.3%) with DAPT. Aspirin plus either clopidogrel or ticagrelor were prescribed in 62.9% and 36.4% of DAPT patients, respectively. Overall, a 14.6% MACE rate was observed at 12 months of follow-up. Patients treated with DAPT had a significantly higher MACE rate than those with SAPT [18.9% vs. 6.0% hazard ratios (HR) 2.62; 95% confidence intervals (CI) 1.22-5.61; P = 0.013], driven by an early excess of non-fatal MI or unplanned PCI. At multiple regression analysis, type 2a SCAD (OR: 3.69; 95% CI 1.41-9.61; P = 0.007) and DAPT regimen (OR: 4.54; 95% CI 1.31-14.28; P = 0.016) resulted independently associated with a higher risk of 12-month MACE. CONCLUSIONS: In this European registry, most patients with SCAD undergoing initial conservative management received DAPT. Yet, at 1-year follow-up, DAPT, as compared with SAPT, was independently associated with a higher rate of adverse cardiovascular events (ClinicalTrial.gov id: NCT04415762).

A Psychoanalytic-Derived Brief Psychotherapeutic Approach in the Treatment of Major Depression: Monotherapy Studies.

Over the years, short term psychodynamic therapy (STPP) has been broadly researched in order to evaluate its efficacy in the treatment of major psychiatric disorders. In particular, a consistent number of studies focused on assessing clinical outcomes of the principal psychodynamic techniques in treating depressive disorders. We conducted a narrative review in which we aimed to evaluate the efficacy of STPP in monotherapy in major depressive disorder and to assess possible features that may correlate with its clinical use. Databases searched were PubMed, Ovid, Scopus, PsycINFO and Cochrane Libraries from inception to July 2022. Our research underlined that STPP in monotherapy is particularly effective in moderately severe depression and in preventing depressive relapses. Moreover, a case-by-case evaluation of its efficacy should be performed when considering STPP for the treatment of major depression with other comorbid psychiatric conditions. Although such key points emerged from scientific evidence, STPP should be better studied in the long-term perspective; further research is needed to define the clinical scenarios in which STPP can be considered a first-line approach as monotherapy in major depressive disorder compared to medications or other types of psychotherapy.

Antithrombotic strategies in patients needing oral anticoagulation undergoing percutaneous coronary intervention: A network meta-analysis.

BACKGROUND: The optimal antithrombotic regimen in patients with a concomitant indication for oral anticoagulation (OAT) presenting with acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI) remains unclear. OBJECTIVES: To perform a network meta-analysis of all randomized controlled trials (RCTs) evaluating different antithrombotic regimens among patients with ACS or undergoing PCI requiring OAT. METHODS: Network meta-analysis was performed in a frequentist framework. Antithrombotic regimens were categorized by OAC type (vitamin K antagonist-based [VKA]; non-VKA OAT [NOAC]) and antiplatelet agents (P2Y inhibitor only: dual therapy [DAT]; P2Y plus aspirin: triple therapy [TAT]). Safety outcomes were Thrombolysis in Myocardial Infarction (TIMI) major bleeding and intracranial hemorrhage (ICH). Efficacy outcomes were cardiovascular death, myocardial infarction, stroke and stent-thrombosis (ST). RESULTS: Five RCTs were included, encompassing 10,797 patients (atrial fibrillation 69-100%, ACS 28-62%, PCI 77-100%). Both VKA and NOAC-based DAT regimens reduced the occurrence of TIMI major bleeding compared to VKA TAT (VKA DAT: RR 0.62, 95% CI 0.39-0.98; NOAC DAT: RR 0.52, 95% CI 0.39-0.70). Nevertheless, only NOAC DAT significantly reduced the occurrence of ICH compared to VKA TAT (RR 0.33, 95% CI 0.17-0.64). Ischemic outcomes were similar among the four treatment regimens. However, numerical, potentially clinically important, higher ST occurrence was observed for NOAC DAT as compared to both VKA TAT (1.50, 95% confidence interval [CI] 0.96-2.33) and NOAC TAT (1.86, 95% CI 0.93-3.73). CONCLUSION: DAT regimens present the highest safety profile among antithrombotic strategies, with a NOAC-specific impact on ICH reduction. NOAC DAT might entail clinically important higher ST occurrence, warranting a case-by-case comprehensive evaluation that integrates patient- and procedure-related residual ischemic risk with the patient-specific bleeding risk.

The prevalence of TTR cardiac amyloidosis among patients undergoing bone scintigraphy.

BACKGROUND: Radiolabeled bisphosphonates bone scintigraphy is highly sensitive in detecting transthyretin (TTR) cardiac amyloidosis; data on the true prevalence of cardiac involvement in TTR amyloidosis are lacking. METHODS AND RESULTS: This retrospective observational, monocentric study aims to estimate the prevalence of positive bone scan suspect for TTR cardiac amyloidosis among an all-comers population who underwent a bone scintigraphy. ECG, echocardiography and clinical status of patients with unexpected cardiac uptake (Perugini score 2-3) who underwent bone scintigraphy with [99mTc]-HDP or [99mTc]-DPD at San Luigi Gonzaga University Hospital between January 2015 and May 2020 have been collected. The prevalence of bone scintigraphy suspect for cardiac involvement was 0.54% (23/4,228). The bone scintigraphy was mainly performed using [99mTc]-HDP (82.9%) and the dominant indication for the test was oncology in the 47.9% of cases. 8 Subjects had a history of neuropathy (34.8%) and 5 of carpal tunnel syndrome (21.7%). 11 Patients suffered a previous episode of heart failure (48%) while 5 patients (21.7%) were totally asymptomatic, without any sign or symptom before the bone scintigraphy making the nuclear examination crucial for an early diagnosis of TTR amyloidosis. CONCLUSION: Bone scintigraphy allows suspecting TTR amyloidosis in a pre-clinical stage of the disease in an all-comers population of patients undergoing bone scintigraphy mainly for oncology reasons.

Ticagrelor or Clopidogrel After an Acute Coronary Syndrome in the Elderly: A Propensity Score Matching Analysis from 16,653 Patients Treated with PCI Included in Two Large Multinational Registries.

PURPOSE: Higher risk of bleeding with ticagrelor over clopidogrel in elderly patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI) has been suggested. We assessed the incidence of major bleedings (MB), reinfarction (re-MI), and all-cause death to evaluate safety and efficacy of ticagrelor versus clopidogrel in such population. METHODS: Real-world registries RENAMI and BleeMACS were merged. The pooled cohort was divided into two groups, clopidogrel versus ticagrelor. Statistical analysis considered patients <75 versus ≥75 years old. Endpoints were BARC 3-5 MB, re-MI, and all-cause death at 1-year follow-up. The study included 16,653 patients (13,153 < 75 and 3500 ≥ 75 years). Ticagrelor was underused in elderly patients (16.3% versus 20.8%, P < 0.001). Using propensity score matching (PSM), two treatment groups of 1566 patients were included in the final analysis. RESULTS: Ticagrelor was able to prevent re-MI (hazard ratio [HR], 0.31; 95% confidence interval [CI], 0.2-0.6; P < 0.001) and all-cause death (HR, 0.60; 95% CI, 0.4-0.9; P = 0.026) irrespective of age. In patients ≥75 years, ticagrelor reduced all-cause death (HR, 0.32; 95% CI, 0.1-0.8; P = 0.012) and re-MI (HR, 0.25; 95% CI, 0.1-1.1, P = 0.072). Moreover, even with the limit of the low number of events, ticagrelor did not significantly increase the incidence of MB (HR, 1.49; 95% CI, 0.70-3.0; P = 0.257). At multiple Cox regression, age (HR, 1.03; 95% CI, 1.02-1.05; P < 0.001) resulted an independent risk factor for bleeding. CONCLUSION: In our study, reflecting the results from two large retrospective, real-world registries, Ticagrelor did not significantly increase MB compared with clopidogrel in elderly patients with ACS treated with PCI, while significantly improving 1-year survival. Further studies on elderly patients are suggested.

Role of Invasive and Non-invasive Imaging Tools in the Diagnosis and Optimal Treatment of Patients with Spontaneous Coronary Artery Dissection.

PURPOSE OF REVIEW: Spontaneous coronary artery dissection (SCAD) is a serious non-atherosclerotic disease, most frequently presenting as an acute coronary syndrome and affecting female patients. Considering that diagnosis of SCAD is often elusive, and its interventional treatment is associated to a higher rate of complications than obstructive atherosclerotic disease, we aim to review all the imaging tools currently available for the optimal diagnosis and treatment of this condition. RECENT FINDINGS: The developments in both invasive and non-invasive imaging alternatives to coronary angiography, such as intravascular ultrasound, optical coherence tomography, and computed coronary angiography, have largely contributed to appraise the epidemiology of SCAD, understand its causative pathophysiological mechanisms, and improve our ability to confirm doubtful cases of SCAD. Intracoronary imaging is also a valuable in deciding the best therapeutic approach and in guiding interventions in those patients requiring percutaneous treatment. Furthermore, non-invasive imaging is a key tool in ruling out significant extracoronary vascular abnormalities which frequently occur in patients with underlying conditions like fibromuscular dysplasia who develop SCAD. Main imaging tools employed in SCAD cases could have advantages and drawbacks. Focusing on different types of SCAD, operators should be able to choose the best imaging technique for diagnosis, management, and follow-up.

Management of acute coronary syndromes requiring coronary angiography in patients with drug reaction with eosinophilia and systemic symptoms syndrome induced by iodinated contrast media: two case reports and narrative review.

Background: Hypersensitivity reactions to iodinated contrast media (ICM) are frequently encountered in clinical practice. Severe manifestations, despite being infrequent, can be life-threatening and represent an issue when re-administration of ICM is required. Clear recommendations on prevention and management of relapses are still lacking. Case summary: We present the cases of two patients presenting with acute coronary syndrome requiring urgent coronary angiography, with an anamnesis of ICM-induced drug reaction with eosinophilia and systemic symptoms syndrome. Both patients safely underwent a coronary angiography with the use of a different ICM (iobitridol) to the one linked to hypersensitivity manifestations, after premedication with corticosteroids and H1 antagonists. Discussion: Our experience highlights that in clinical situations in which the use of ICM is urgently needed, premedication with corticosteroids and H1 antagonists together with the choice of an alternative contrast agent (when the culprit is known) represents an effective strategy to perform a potentially life-saving procedure while avoiding serious systemic allergic reactions.

[The IN-HF Registry: the history and the scientific production for the Italian cardiology community]. / Il programma IN-HF: la storia e la produzione scientifica a favore della comunità cardiologica italiana.

The Italian Network on Congestive Heart Failure (IN-CHF) project, later known as IN-HF Online, was launched in 1995 to provide the Italian cardiology community with a digital tool, standardized across the country, for managing outpatients with heart failure (HF), that enabled the creation of a database for clinical, educational and scientific purposes. During its almost three decades of activity, this observational research program has achieved highly positive scientific results. Indeed, IN-HF fostered professional relationships among individuals working in different centers, established a cultural network for the care of HF patients, periodically updated on the scientific advances, and allowed the assessment of several clinical, epidemiological, and prognostic features. These findings have been published in numerous national and international journals, as summarized in the present overview.

Gender differences in the development of heart failure after acute coronary syndrome: Insight from the CORALYS registry.

BACKGROUND: Impact of gender on heart remodeling after acute coronary syndrome (ACS) and consequently on development of heart failure (HF) remains to be elucidated. METHODS: CORALYS is a multicenter, retrospective, observational registry enrolling consecutive patients admitted for ACS and treated with percutaneous coronary intervention. HF hospitalization was the primary endpoint while all-cause mortality and the composite endpoint of incidence of first HF hospitalization and cardiovascular mortality were the secondary ones. RESULTS: Among 14,699 patients enrolled in CORALYS registry, 4578 (31%) were women and 10,121 (69%) males. Women were older, had more frequently hypertension and diabetes and less frequently smoking habit. History of myocardial infarction (MI), STEMI at admission and multivessel disease were less common in women. After median follow up of 2.9 ± 1.8 years, women had higher incidence of primary and secondary endpoints and female sex was an independent predictor of HF hospitalization (HR 1.26;1.05-1.50; p = 0.011) and cardiovascular death/HF hospitalization (HR 1.18;1.02-1.37; p = 0.022). At multivariable analysis women and men share as predictors of HF diabetes, history of cancer, chronic kidney disease, atrial fibrillation, complete revascularization and left ventricular ejection fraction. Chronic obstructive pulmonary disease (HR 2.34;1.70-3.22, p < 0.001) and diuretics treatment (HR 1.61;1.27-2.04, p < 0.001) were predictor of HF in men, while history of previous MI (HR 1.46;1.08-1.97, p = 0.015) and treatment with inhibitors of renin-angiotensin system (HR 0.69;0,49-0.96 all 95% CI, p = 0.030) in women. CONCLUSIONS: Women are at increased risk of HF after ACS and gender seems to be an outcome-modifier of the relationship between a variable and primary outcome.

Association between hormone therapy and short-term cardiovascular events in women with spontaneous coronary artery dissection.

INTRODUCTION AND OBJECTIVES: Changes in sex hormone levels are a known triggering factor for spontaneous coronary artery dissection (SCAD) in women. However, it is unknown whether exposure to exogenous hormone therapy (HT) at the time of SCAD presentation modifies the clinical course of this condition. We investigated the association between HT in female patients presenting with SCAD and short-term clinical outcomes. METHODS: We enrolled consecutive patients presenting with SCAD from the DISCO-IT/SPA (dissezioni spontanee coronariche Italian-Spanish) registry. Women on HT (estrogens, progestagens, or gonadotropins) at the time of presentation were identified, and their clinical characteristics and short-term outcomes were compared with those not receiving active HT. The outcome measure was nonfatal myocardial infarction and/or unplanned percutaneous coronary intervention during the first 28 days after the index catheterization. RESULTS: Of 224 women presenting with SCAD (mean age 52.0±10.0 years), 39 (17.4%) were currently using HT while 185 (82.6%) were not. No significant differences were noted in the baseline demographics, clinical presentation, angiographic features, or initial treatment received between the 2 groups. All patients on systemic HT (n=36, 92%) discontinued it at the time of diagnosis. The composite outcome occurred in 7 (17.9%) patients with prior HT compared with 14 (7.6%) without (P=.039). After multivariable adjustment, HT remained associated with the composite outcome recorded in the first 28 days of follow-up (HR, 3.53; 95%CI, 1.30-9.61; P=.013). CONCLUSIONS: In women with SCAD, exposure to HT at the time of clinical presentation was associated with short-term recurrent cardiovascular events such as nonfatal myocardial infarction and/or unplanned percutaneous revascularization.

Impact of Complete Revascularization on Development of Heart Failure in Patients With Acute Coronary Syndrome and Multivessel Disease: A Subanalysis of the CORALYS Registry.

Background The impact of complete revascularization (CR) on the development of heart failure (HF) in patients with acute coronary syndrome and multivessel coronary artery disease undergoing percutaneous coronary intervention remains to be elucidated. Methods and Results Consecutive patients with acute coronary syndrome with multivessel coronary artery disease from the CORALYS (Incidence and Predictors of Heart Failure After Acute Coronary Syndrome) registry were included. Incidence of first hospitalization for HF or cardiovascular death was the primary end point. Patients were stratified according to completeness of coronary revascularization. Of 14 699 patients in the CORALYS registry, 5054 presented with multivessel disease. One thousand four hundred seventy-three (29.2%) underwent CR, while 3581 (70.8%) did not. Over 5 years follow-up, CR was associated with a reduced incidence of the primary end point (adjusted hazard ratio [HR], 0.66 [95% CI, 0.51-0.85]), first HF hospitalization (adjusted HR, 0.67 [95% CI, 0.49-0.90]) along with all-cause death and cardiovascular death alone (adjusted HR, 0.74 [95% CI, 0.56-0.97] and HR, 0.56 [95% CI, 0.38-0.84], respectively). The results were consistent in the propensity-score matching population and in inverse probability treatment weighting analysis. The benefit of CR was consistent across acute coronary syndrome presentations (HR, 0.59 [95% CI, 0.39-0.89] for ST-segment elevation myocardial infarction and HR, 0.71 [95% CI, 0.50-0.99] for non-ST-elevation acute coronary syndrome) and in patients with left ventricular ejection fraction >40% (HR, 0.52 [95% CI, 0.37-0.72]), while no benefit was observed in patients with left ventricular ejection fraction ≤40% (HR, 0.77 [95% CI, 0.37-1.10], P for interaction 0.04). Conclusions CR after acute coronary syndrome reduced the risk of first hospitalization for HF and cardiovascular death, as well as first HF hospitalization, and cardiovascular and overall death both in patients with ST-segment elevation myocardial infarction and non-ST-elevation acute coronary syndrome.

IncidenCe and predictOrs of heaRt fAiLure after acute coronarY Syndrome: The CORALYS registry.

BACKGROUND: Previous studies investigating predictors of Heart Failure (HF) after acute coronary syndrome (ACS) were mostly conducted during fibrinolytic era or restricted to baseline characteristics and diagnoses prior to admission. We assessed the incidence and predictors of HF hospitalizations among patients treated with percutaneous coronary intervention (PCI) for ACS. METHODS AND RESULTS: CORALYS is a multicenter, retrospective, observational registry including consecutive patients treated with PCI for ACS. Patients with known history of HF or reduced left ventricular ejection fraction (LVEF) were excluded. Incidence of HF hospitalizations was the primary endpoint. The composite of HF hospitalization or cardiovascular death, and cardiovascular and all-cause death were the secondary endpoints. Predictors of HF hospitalizations and the impact of HF hospitalization on cardiovascular and all-cause death were assessed by means of multivariable Cox proportional hazards model.14699 patients were included. After 2.9 ± 1.8 years, the incidence of HF hospitalizations was 12.7%. Multivariable analysis identified age, diabetes, chronic kidney disease, previous myocardial infarction, atrial fibrillation, pulmonary disease, GRACE risk-score ≥ 141, peripheral artery disease, cardiogenic shock at admission and LVEF ≤40% as independently associated with HF hospitalizations. Complete revascularization was associated with a lower risk of HF (HR 0.46,95%CI 0.39-0.55). HF hospitalization was associated with higher risk of CV and all-cause death (HR 1.89,95%CI 1.5-2.39 and HR 1.85,95%CI 1.6-2.14, respectively). CONCLUSIONS: Incidence of HF hospitalizations among patients treated with PCI for ACS is not negligible and is associated with detrimental impact on patients' prognosis. Several variables may help to assess the risk of HF after ACS.
