Cardiac amyloidosis, increasingly recognized for its significant impact on global heart health and patient survival, demands a thorough review to understand its complexity and the urgency of improved management strategies. As a cause of cardiomyopathy and heart failure, particularly in patients with aortic stenosis and atrial fibrillation, this condition also relates to higher incidences of dementia in the affected populations. The objective of this review was to integrate and discuss the latest advancements in diagnostics and therapeutics for cardiac amyloidosis, emphasizing the implications for patient prognosis. We evaluated the latest literature from major medical databases such as PubMed and Scopus, focusing on research from 2020 to 2024, to gather comprehensive insights into the current landscape of this condition. Insights from our review highlight the complex pathophysiology of cardiac amyloidosis and the diagnostic challenges it presents. We detail the effectiveness of emerging treatments, notably gene silencing therapies like patisiran and vutrisiran, which offer transformative potential by targeting the production of amyloidogenic proteins. Additionally, the stabilization therapy acoramidis shows promise in modifying disease progression and improving clinical outcomes. This review underscores the critical need for updated clinical guidelines and further research to expand access to groundbreaking therapies and enhance disease management. Advocating for continued research and policy support, we emphasize the importance of advancing diagnostic precision and treatment effectiveness, which are vital for improving patient outcomes and addressing this debilitating disease globally., Competing Interests: The authors declare no conflict of interest to ensure the impartiality of the review., (Copyright 2024, Llerena-Velastegui.)

Shifts from deep to moderate hypothermic circulatory arrest (HCA) in aortic arch surgery necessitate an examination of their differential impacts on neurocognitive functions, especially structured verbal memory, given its significance for patient recovery and quality of life. This study evaluates and synthesizes evidence on the effects of deep (≤20.0 °C), low-moderate (20.1-24.0 °C), and high-moderate (24.1-28.0 °C) hypothermic temperatures on structured verbal memory preservation and overall cognitive health in patients undergoing aortic arch surgery. We evaluated the latest literature from major medical databases such as PubMed and Scopus, focusing on research from 2020 to 2024, to gather comprehensive insights into the current landscape of temperature management during HCA. This comparative analysis highlights the viability of moderate hypothermia (20.1-28.0 °C), supported by recent trials and observational studies, as a method to achieve comparable neuroprotection with fewer complications than traditional deep hypothermia. Notably, low-moderate and high-moderate temperatures have been shown to support substantial survival rates, with impacts on structured verbal memory preservation that necessitate careful selection based on individual surgical risks and patient profiles. The findings advocate for a nuanced approach to selecting hypothermic protocols in aortic arch surgeries, emphasizing the importance of tailoring temperature management to optimize neurocognitive outcomes and patient recovery. This study fills a critical gap in the literature by providing evidence-based recommendations for temperature ranges during HCA, calling for ongoing updates to clinical guidelines and further research to refine these recommendations. The implications of temperature on survival rates, complications, and success rates underpin the necessity for evolving cardiopulmonary bypass techniques and cerebral perfusion strategies to enhance patient outcomes in complex cardiovascular procedures.

Background: Ischemic heart disease (IHD) is a major global health issue and a leading cause of death. This study compares the effectiveness of percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in the management of IHD, focusing on their impact on revascularization, myocardial infarction (MI), and post-procedural stroke. This study aimed to evaluate and compare the effectiveness of PCI and CABG in treating IHD based on an exhaustive literature review of the past 5 years, emphasizing recent advancements and outcomes in IHD management., Methods: A comprehensive literature review analyzed 32 randomized controlled trials (RCTs) retrieved from databases such as PubMed, Cochrane Library, and Google Scholar. The study specifically assessed the incidences of revascularization, stroke, and MI in patients treated with either PCI or CABG. The comparison between CABG and PCI exclusively focused on lesions with a SYNTAX score exceeding 32., Results: Our findings highlight CABG's significant efficacy over PCI in reducing revascularization and MI. The aggregated Mantel-Haenszel (M-H) value for revascularization was 1.85 (95% confidence interval (CI): 1.65 - 2.07), signifying CABG's advantage. Additionally, CABG demonstrated superior performance in diminishing MI occurrences (M-H = 2.71, 95% CI: 1.13 - 6.53). In contrast, PCI was more effective in reducing stroke (M-H = 0.80, 95% CI: 0.60 - 1.10)., Conclusion: The study confirms CABG's superiority in reducing revascularization and MI in IHD patients, highlighting PCI's effectiveness in reducing stroke risk. These findings underscore the importance of personalized treatment strategies in IHD management and emphasize the need for ongoing research and evidence-based guidelines to aid in treatment selection for IHD patients., Competing Interests: The authors declare no conflict of interest to ensure the impartiality of the review., (Copyright 2024, Llerena-Velastegui et al.)
