Abstract
As a result of the widespread use of reperfusion therapies and secondary prevention over the last 30 years, there has been a dramatic reduction in the risk of mortality and development of heart failure (HF) following acute myocardial infarction (MI). Despite this, the development of chronic HF remains a common occurrence in the days, months, and years following MI. Neurohormonal inhibition remains the mainstay of pharmacologic prevention of HF following MI, with recent trials showing an additive benefit of a neprilysin inhibitor or a sodium glucose co-transporter 2 inhibitor in reducing the risk of development of HF but no significant effect on mortality. Novel imaging tools may help refine risk stratification in high-risk patients and allow greater targeting of preventative therapies in patients most likely to benefit. Research is ongoing into novel therapies aiming to minimize the degree of myocardial damage and prevention of progressive adverse remodeling following MI.

Abstract
Coronary artery bypass (CABG) has evolved over the decades, supported by scientific evidence from robust studies. The downgrade of the recommendation for CABG in patients with multivessel coronary artery disease proposed by the 2021 ACC/AHA/SCAI Guideline for Coronary Artery Revascularization and the 2023 ACC/AHA Chronic Coronary Disease Guidelines has brought this discussion to the fore, with prestigious cardiothoracic surgery societies such as AATS and STS not supporting these recommendations. The purpose of this article is to broaden this discussion in light of published studies.

Abstract
The concept of myocardial viability is usually referred to areas of the myocardium, which show contractile dysfunction at rest and in which contractility is expected to improve after revascularization. The traditional paradigm states that an improvement in function after revascularization leads to improved health outcomes and that assessment of myocardial viability in patients with ischaemic left ventricular dysfunction (ILVD) is a prerequisite for clinical decisions regarding treatment. A range of retrospective observational studies supported this 'viability hypothesis'. However, data from prospective trials have diverged from earlier retrospective studies and challenge this hypothesis. Traditional binary viability assessment may oversimplify ILVD's complexity and the nuances of revascularization benefits. A conceptual shift from the traditional paradigm centred on the assessment of viability as a dichotomous variable to a more comprehensive approach encompassing a thorough understanding of ILVD's complex pathophysiology and the salutary effect of revascularization in the prevention of myocardial infarction and ventricular arrhythmias is required.

Abstract
The burden of coronary artery disease (CAD) is large and growing, commonly presenting with comorbidities and older age. Patients may benefit from coronary revascularisation with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG), yet half of patients with CAD who would benefit from revascularisation fall outside the eligibility criteria of trials to date. As such, the choice of revascularisation procedures varies depending on the CAD anatomy and complexity, surgical risk and comorbidities, the patient's preferences and values, and the treating team's expertise. The recent American guidelines on coronary revascularisation are comprehensive in describing recommendations for PCI, CABG, or conservative management in patients with CAD. However, individual challenging patient presentations cannot be fully captured in guidelines. The aim of this narrative review is to summarise common clinical scenarios that are not sufficiently described by contemporary clinical guidelines and trials in order to inform heart team members and trainees about the nuanced considerations and available evidence to manage such cases. We discuss clinical cases that fall beyond the current guidelines and summarise the relevant evidence evaluating coronary revascularisation for these patients. In addition, we highlight gaps in knowledge based on a lack of research (eg, ineligibility of certain patient populations), underrepresentation in research (eg, underenrollment of female and non-White patients), and the surge in newer minimally invasive and hybrid techniques. We argue that ultimately, evidence-based medicine, patient preference, shared decision making, and effective heart team communications are necessary to best manage complex CAD presentations potentially benefitting from revascularisation with CABG or PCI.

Abstract
PURPOSE OF REVIEW We aim to reevaluate how the assessment of myocardial viability can guide optimal treatment strategies for patients with ischemic cardiomyopathy (ICM) based on a more contemporary understanding of the mechanism of benefit of revascularization. RECENT FINDINGS The assessment of viability in left ventricular (LV) segments with diminished contraction has been proposed as key to predict the benefit of revascularization and, therefore, as a requisite for the selection of patients to undergo this form of treatment. However, data from prospective trials have diverged from earlier retrospective studies. Traditional binary viability assessment may oversimplify ICM's complexity and the nuances of revascularization benefits. A conceptual shift from the traditional paradigm centered on the assessment of viability as a dichotomous variable to a more comprehensive approach encompassing a thorough understanding of ICM's complex pathophysiology and the salutary effect of revascularization in the prevention of myocardial infarction and ventricular arrhythmias is required.
