Artificial intelligence (AI) offers new opportunities in cardio-oncology for early detection, risk stratification, and personalized management of cardiovascular complications in cancer patients. By leveraging data from electronic health records, blood biomarkers, imaging tests such as echocardiography, electrocardiograms, and wearables, AI models can facilitate prediction, detection and response to treatment of cardiovascular disease entities, pre-existing and developing as a consequence of cancer therapy. Specific to the latter, referred to as cardiotoxicity, widespread adoption has been hindered by the limited availability of large datasets for model training, insufficient external validation, and challenges in integrating AI tools into routine clinical workflows. Future progress will depend on advancements in AI technologies, rigorous multi-center validation, development of explainable models, and seamless integration into clinical practice. Barriers, not only from a systems perspective, but also from a provider and most importantly from a patient perspective will need to be addressed for successful implementation. With a broad multidisciplinary perspective and patient focus, AI can advance cardio-oncology care and improve outcomes for patients with cancer.

Atrial fibrillation (AF) increases the risk of stroke and cognitive decline. While anticoagulation with vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs) prevents stroke, their role in reducing dementia risk in patients with AF remains unclear. To evaluate the effect of anticoagulation therapy on dementia incidence in patients with AF, comparing DOACs versus VKAs. We systematically reviewed PubMed, Scopus, Web of Science, Embase, and Cochrane. Systematic reviews and meta-analyses evaluating the effects of anticoagulation therapies on dementia were included. A total of 11 systematic reviews and meta-analyses were included in this umbrella review. Findings from 6 systematic reviews showed that OAC use was associated with a reduced risk of incident dementia in patients with AF, with effect estimates (RR/HR) ranging from 0.46 [0.28-0.78] to 0.79 [0.67-0.93]. For DOACs versus VKAs, most studies found a lower risk of dementia with DOACs, with effect sizes ranging from HR: 0.51 [0.37-0.71] to RR: 0.88 [0.82-0.94]. However, two studies found no significant difference between DOACs and warfarin in dementia risk (OR: 0.65 [0.34-1.25] and RR: 0.91 [0.75-1.12], respectively). Anticoagulation therapy, particularly with DOACs, may help reduce the risk of dementia in AF patients. The evidence remains of moderate to low certainty, and further high-quality, long-term randomized controlled trials are needed to confirm these findings and explore the neuroprotective mechanisms of OACs.

Parkinson's disease (PD) is a synucleinopathy best known for its motor symptoms, but emerging research shows it also impacts the cardiovascular system. In this paper, we explore the association between PD and cardiovascular disease (CVD), reviewing six key categories: cardiac dysautonomia, coronary artery disease, arrhythmias, cardiomyopathy, heart valve disease, and heart failure. We also discuss risk factors, epidemiology, and overlapping pathophysiology. Cardiac dysautonomia is the most frequently reported cardiovascular issue in PD and includes orthostatic hypotension, postprandial hypotension, supine hypertension, and nocturnal non-dipping blood pressure. PD also appears to be positively associated with coronary artery disease. Early-stage PD is linked to atrial fibrillation, but overall, there is no consistent increase in arrhythmias outside of certain PD medications. Structural and functional cardiac changes such as left ventricular hypertrophy and diastolic dysfunction have also been reported in PD, which may predispose to heart failure and cardiomyopathy. Dopamine agonists pergolide and cabergoline are associated with valve regurgitation, but this seems to be drug-related rather than caused by PD. Shared risk factors like aging, male sex, diabetes, and inflammation help explain the PD-CVD connection. However, some CVD risk factors like high LDL and smoking are associated with lower PD risk. Autonomic dysfunction, impaired lipid and glucose metabolism, and chronic inflammation may all contribute to disease overlap. Our review consolidates existing research to highlight the importance of recognizing cardiovascular manifestations in PD, which may present before motor symptoms. This has important implications for earlier diagnosis, better screening, and more effective management of PD.

The 2025 European Society of Cardiology (ESC) guidelines and the 2024-2025 American College of Cardiology (ACC) consensus documents redefine the management of myocarditis and pericarditis, with notable convergence, yet key differences. Both emphasize early, accurate diagnosis, particularly through cardiac magnetic resonance (CMR), which now often supersedes immediate biopsy in stable, uncomplicated cases of acute myocarditis. The ESC introduces a unified "inflammatory myopericardial syndrome" (IMPS) framework encompassing myocarditis, pericarditis, and overlap syndromes, while the ACC provides separate pathways, including a novel four-stage clinical classification of myocarditis. Therapeutically, both endorse non-steroidal anti-inflammatory drugs (NSAIDs) and colchicine for pericarditis and myopericarditis, and heart failure-directed therapy for myocarditis, while reserving immunosuppression for select cases. Importantly, interleukin-1 (IL-1) blockade has emerged as a pivotal therapy in recurrent pericarditis, receiving a Class I recommendation in ESC guidelines and strong endorsement in ACC guidance. Prognostic assessment focuses on identifying high-risk features and structured follow-up with imaging and biomarkers. Divergences in terminology, staging, and diagnostic thresholds underscore opportunities for further harmonization. The ESC and ACC documents align in a patient-tailored, evidence-informed approach to management.
