Introduction

The 2023 ESC Guidelines offer comprehensive recommendations for managing acute coronary syndromes (ACS) [1]. They put a strong emphasis on early diagnosis, thorough risk stratification, and personalized treatment approaches [1]. These strategies include critical elements like revascularization, various antithrombotic therapies, and essential secondary prevention measures [1]. The overarching aim of these guidelines is to establish standardized care, thereby significantly improving patient outcomes [1]. A detailed review provides insights into contemporary antithrombotic therapy tailored for ACS patients who undergo percutaneous coronary intervention [2]. This therapy involves the optimal application of antiplatelet agents and anticoagulants [2]. The challenge is balancing their efficacy in preventing ischemic events with the inherent risk of bleeding complications [2]. It is important to implement personalized approaches based on individual patient characteristics and their specific clinical presentation [2]. Advanced multimodality imaging techniques are indispensable in ACS management [3]. These techniques are vital for accurate diagnosis, precise risk stratification, and guiding therapeutic decisions effectively [3]. The review highlights the significant utility of tools such as echocardiography, cardiac Magnetic Resonance Imaging (MRI), Computed Tomography (CT) angiography, and nuclear imaging [3]. These imaging modalities are crucial for assessing myocardial damage, pinpointing culprit lesions, and evaluating overall prognosis, all of which contribute to enhanced patient management [3]. Emerging biomarkers present promising avenues for earlier and more precise diagnosis and risk stratification in ACS cases [4]. This particular review delves into novel markers that extend beyond conventional troponins [4]. The focus is on those specific indicators of myocardial injury and ischemia [4]. Such advancements are expected to significantly enhance clinical decision-making and enable highly personalized treatment strategies for patients [4]. A narrative review sheds light on recent advancements in secondary prevention strategies following an ACS event [5]. It strongly emphasizes the optimization of pharmacotherapy, implementation of crucial lifestyle modifications, and engagement in cardiac rehabilitation programs [5]. These measures are designed to effectively reduce recurrent cardiovascular events and improve long-term prognosis [5]. The review consistently underscores the critical importance of a holistic and truly personalized approach to patient care [5]. Sex differences markedly influence the pathophysiology, clinical presentation, and ultimate outcomes of ACS [6]. This comprehensive paper explores how distinct biological factors, an individual's hormonal status, and broader societal influences contribute to varied diagnostic and therapeutic approaches [6]. The work strongly advocates for the integration of sex-specific considerations into patient care [6]. This is essential to optimize treatment and improve prognosis for both men and women experiencing ACS [6]. Artificial Intelligence (AI) holds immense potential to revolutionize ACS management [7]. AI applications range from significantly enhancing diagnostic accuracy and predicting patient risk more effectively to optimizing various treatment strategies [7]. This review specifically discusses the current applications and future directions of AI, including advanced machine learning algorithms [7]. These technologies are poised to play a pivotal role in improving patient care and overall outcomes within the complex landscape of ACS [7]. A deep understanding of the long-term prognosis after an ACS event is absolutely vital for patient care planning [8]. A comprehensive population-based study offers critical insights into the enduring risks and the various factors that influence outcomes years after an initial ACS event [8]. This study highlights the paramount importance of sustained secondary prevention efforts and ongoing surveillance [8]. These measures are necessary to mitigate future cardiovascular complications effectively [8]. Managing ACS in older adults poses unique and multifaceted challenges [9]. These difficulties arise from prevalent comorbidities, the complexities of polypharmacy, and altered physiological responses characteristic of this vulnerable population [9]. This article meticulously reviews current evidence and discusses tailored approaches for accurate diagnosis, appropriate revascularization, and pharmacotherapy [9]. The aim is to improve outcomes in this group while diligently minimizing associated risks [9]. Inflammation plays a critical and intricate role in the pathophysiology of ACS [10]. Its involvement spans from the initial plaque rupture that triggers the event, through subsequent myocardial injury, and into the complex mechanisms of tissue repair [10]. This review meticulously explores the fundamental underlying inflammatory mechanisms at play [10]. It also discusses novel biomarkers and innovative therapeutic strategies specifically designed to target inflammation [10]. These advancements offer promising new avenues for significantly improving prognosis and reducing adverse events in ACS patients [10].

Description

The management of acute coronary syndromes (ACS) involves comprehensive strategies, as outlined by the 2023 ESC Guidelines [1]. These guidelines emphasize early diagnosis, thorough risk stratification, and tailored treatment plans [1]. Key therapeutic components include timely revascularization, various antithrombotic therapies, and robust secondary prevention measures [1]. The overarching aim is to standardize care and improve patient outcomes [1]. Specialized attention is given to antithrombotic therapy for ACS patients undergoing percutaneous coronary intervention [2]. This review details the optimal use of antiplatelet agents and anticoagulants, highlighting the careful balance between preventing ischemic events and mitigating bleeding risk [2]. This approach necessitates personalized strategies based on individual patient characteristics and clinical presentation [2].

Accurate diagnosis and precise risk stratification in ACS are significantly bolstered by advanced multimodality imaging techniques [3]. A review highlights the utility of a suite of imaging tools, including echocardiography, cardiac Magnetic Resonance Imaging (MRI), Computed Tomography (CT) angiography, and nuclear imaging [3]. These methods are invaluable for assessing myocardial damage, identifying culprit lesions, and evaluating prognosis, contributing to enhanced patient management [3]. Parallel to imaging advancements, emerging biomarkers present promising avenues for earlier and more refined risk stratification [4]. This research explores novel markers beyond traditional troponins [4]. The focus lies on indicators reflecting myocardial injury and ischemia, with the potential to enhance clinical decision-making and enable personalized treatment strategies [4].

Secondary prevention strategies following an ACS event are critical for improving long-term patient health [5]. A narrative review highlights recent advancements in this area, emphasizing the optimization of pharmacotherapy, vital lifestyle modifications, and active cardiac rehabilitation programs [5]. These efforts are essential for reducing recurrent cardiovascular events and improving long-term prognosis [5]. This approach underscores a holistic and patient-centered personalized care model [5]. Furthermore, understanding long-term prognosis after ACS is vital for effective ongoing patient care [8]. A population-based study offers crucial insights into enduring risks and factors influencing outcomes years after an initial ACS event [8]. This research highlights the necessity for sustained secondary prevention efforts and diligent ongoing surveillance to mitigate future cardiovascular complications [8].

Managing ACS in specific patient populations, such as older adults, presents unique and complex challenges [9]. These difficulties arise from comorbidities, polypharmacy, and altered physiological responses characteristic of this vulnerable demographic [9]. Current evidence reviews discuss tailored approaches to diagnosis, revascularization procedures, and pharmacotherapy specifically for older adults [9]. The objective is to improve outcomes while diligently minimizing associated risks [9]. Beyond age, sex differences significantly influence the pathophysiology, clinical presentation, and outcomes of ACS [6]. This paper explores how distinct biological factors, hormonal status, and societal influences contribute to varied diagnostic and therapeutic approaches [6]. It strongly advocates for sex-specific considerations in patient care, essential to optimize treatment and improve prognosis for both men and women [6].

Inflammation plays a critical and intricate role in the pathophysiology of ACS [10]. Its involvement spans from plaque rupture to myocardial injury and tissue repair [10]. This review meticulously explores underlying inflammatory mechanisms [10]. It also discusses novel biomarkers and innovative therapeutic strategies designed to target inflammation [10]. These advancements offer promising avenues for improving patient prognosis and reducing adverse events [10]. Looking towards the future, Artificial Intelligence (AI) holds immense potential to revolutionize ACS management [7]. AI applications range from enhancing diagnostic accuracy and predicting patient risk to optimizing treatment strategies [7]. This review discusses current applications and future

z directions of AI, including advanced machine learning algorithms, emphasizing their pivotal role in improving patient care and overall outcomes [7].
