Elderly patients diagnosed with acute coronary syndromes (ACS) represent a growing demographic population. These patients typically present more comorbidities and experience poorer outcomes compared to younger patients. Furthermore, they are less frequently subjected to revascularization procedures and are less likely to receive evidence-based medications in both the short and long-term periods. Assessing frailty is crucial in elderly patients with ACS because it can influence management decisions, as well as risk stratification and prognosis. Indeed, treatment decisions should consider geriatric syndromes, frailty, polypharmacy, sarcopenia, nutritional deficits, prevalence of comorbidities, thrombotic risk, and, at the same time, an increased risk of bleeding. Rigorous clinical assessments, clear revascularization criteria, and tailored approaches to antithrombotic therapy are essential for guiding personalized treatment decisions in these individuals. Assessing frailty helps healthcare providers identify patients who may benefit from targeted interventions to improve their outcomes and quality of life. Elderly individuals who experience ACS remain significantly underrepresented and understudied in randomized controlled trials. For this reason, the occurrence of ACS in the elderly continues to be a particularly complex issue in clinical practice, and one that clinicians increasingly have to address, given the general ageing of populations. This review aims to address the complex aspects of elderly patients with ACS to help clinicians make therapeutic decisions when faced with such situations.

Atrial fibrillation (AF) is the most prevalent sustained supraventricular arrhythmia, particularly in older adults, with its incidence increasing dramatically with age. This condition is a significant contributor to morbidity and mortality, being closely linked to an elevated risk of heart failure, ischemic stroke, systemic thromboembolism, and dementia. The complexities of managing AF in the elderly arise from age-related physiological changes, comorbidities, frailty, and the challenges of polypharmacy. Therapeutic strategies must balance efficacy and safety, tailoring interventions to the individual’s health status, life expectancy, and personal preferences. This review explores the latest evidence-based approaches to managing AF in elderly patients, focusing on the nuanced application of rate and rhythm control strategies, anticoagulation, and emerging insights into the relationship between AF and cognitive impairment.

Takotsubo syndrome (TTS) is an acute, reversible form of left ventricular dysfunction, typically triggered by emotional or physical stress. The hallmark feature is reversible regional wall motion abnormality extending beyond a single coronary distribution, most commonly presenting with an apical ballooning pattern. The pathophysiology is multifactorial, encompassing neurohormonal dysregulation, catecholamine-mediated toxicity, microvascular dysfunction, oxidative stress, inflammation, and metabolic disturbances. Nonetheless, despite growing recognition, an evidence gap persists in diagnosing TTS. Meanwhile, TTS is classified within myocardial infarction with non-obstructive coronary arteries (MINOCAs) and frequently treated as a diagnosis of exclusion. Further complicating the diagnostic algorithm, emerging evidence indicates that TTS and coronary artery disease (CAD) may coexist, suggesting a potential bidirectional relationship rather than a bystander phenomenon. Moreover, TTS shares several pathophysiological mechanisms with coronary microvascular dysfunction syndromes: angina with non-obstructive coronary arteries (ANOCAs) and ischemia with non-obstructive coronary arteries (INOCAs). These overlaps underscore the need for rigorous differential diagnosis and careful comprehensive evaluation of hemodynamic significance, plaque morphology, and microvascular phenotyping to enhance clinical recognition and optimize therapeutic decision-making. This review synthesizes current evidence on the diagnosis and management of TTS, emphasizing the intersection between TTS and coronary and microvascular disorders to promote a more targeted, mechanism-based therapeutic approach.
