Diastolic Dysfunction in Hypertension: A Comprehensive Review of Pathophysiology, Diagnosis, and Treatment.

Diastolic dysfunction refers to impaired relaxation or filling of the ventricles during the diastolic phase of the cardiac cycle. Left ventricular diastolic dysfunction (LVDD) is common in hypertensive individuals and is associated with increased morbidity and mortality. LVDD serves as a critical precursor to heart failure (HF), particularly heart failure with preserved ejection fraction (HFpEF). The pathophysiology of LVDD in hypertension is complex, involving alterations in cardiac structure and function, neurohormonal activation, and vascular stiffness. While the diagnosis of LVDD relies primarily on echocardiography, management remains challenging due to a lack of specific treatment guidelines for LVDD. This review offers an overview of the pathophysiological mechanisms underlying LVDD in hypertension, diagnostic methods, clinical manifestations, strategies for managing LVDD, and prospects for future research.

Cardiac Amyloidosis: A Comprehensive Review of Pathophysiology, Diagnostic Approach, Applications of Artificial Intelligence, and Management Strategies.

Cardiac amyloidosis (CA) is a serious and often fatal condition caused by the accumulation of amyloid fibrils in the heart, leading to progressive heart failure. It involves the misfolding of normally soluble proteins into insoluble amyloid fibrils, with transthyretin and light-chain amyloidosis being the most common forms affecting the heart. Advances in diagnostics, especially cardiac magnetic resonance imaging and non-invasive techniques, have improved early detection and disease management. Artificial intelligence has emerged as a diagnostic tool for cardiac amyloidosis, improving accuracy and enabling earlier intervention through advanced imaging analysis and pattern recognition. Management strategies include volume control, specific pharmacotherapies like tafamidis, and addressing arrhythmias and advanced heart failure. However, further research is needed for novel therapeutic approaches, the long-term effectiveness of emerging treatments, and the optimization of artificial intelligence applications in clinical practice for better patient outcomes.The article aims to provide an overview of CA, outlining its pathophysiology, diagnostic advancements, the role of artificial intelligence, management strategies, and the need for further research.

Spontaneous Coronary Artery Dissection and Tear Repair: A Comprehensive Review of Pathophysiology, Diagnosis, and Therapeutic Interventions

Spontaneous Coronary Artery Dissection (SCAD) represents a rare but significant cause of acute coronary syndrome, predominantly affecting young to middle-aged women without traditional cardiovascular risk factors. The pathophysiology of SCAD involves the spontaneous development of an intimal tear or the formation of an intramural hematoma, leading to coronary artery obstruction and myocardial ischemia. Diagnosing SCAD is challenging due to its varied presentation and the need for high-resolution imaging techniques. Management strategies for SCAD are diverse, ranging from conservative medical therapy to percutaneous coronary intervention (PCI) and, in severe cases, surgical repair. This review aims to provide a detailed analysis of the pathophysiological mechanisms, diagnostic criteria, and therapeutic approaches for the repair of SCAD, highlighting recent advancements in interventional cardiology and surgical techniques.

Diabetic foot ulcer: A comprehensive review of pathophysiology and management modalities.

Diabetic foot ulcer (DFU) is a debilitating and severe manifestation of uncontrolled and prolonged diabetes that presents as ulceration, usually located on the plantar aspect of the foot. Approximately 15% of individuals with diabetes will eventually develop DFU, and 14%-24% of them will require amputation of the ulcerated foot due to bone infection or other ulcer-related complications. The pathologic mechanisms underlying DFU are comprise a triad: Neuropathy, vascular insufficiency, and secondary infection due to trauma of the foot. Standard local and invasive care along with novel approaches like stem cell therapy pave the way to reduce morbidity, decrease amputations, and prevent mortality from DFU. In this manuscript, we review the current literature with focus on the pathophysiology, preventive options, and definitive management of DFU.

Idiopathic vitreomacular traction and macular hole: a comprehensive review of pathophysiology, diagnosis, and treatment

Posterior vitreous detachment (PVD) is a common phenomenon in the aging eye. However, this may be complicated by persistent symptomatic vitreomacular adhesions that exert tractional forces on the macula (vitreomacular traction; VMT). VMT itself may be associated with epiretinal membrane formation and the development of idiopathic macular holes (IMH). Such pathologies may cause visual disturbances, including metamorphopsia, photopsia, blurred vision, and decreased visual acuity, which impact an individual's quality of life. Technologies such as optical coherence tomography allow an increasingly more accurate visualisation of the macular anatomy, including quantification of macular hole characteristics, and this facilitates treatment decision-making. Pars plana vitrectomy remains the primary treatment option for many patients with VMT or IMH; for the latter, peeling of the inner limiting membrane (ILM) of the retina has shown improved outcomes when compared with no ILM peeling. The development of narrow-gauge transconjunctival vitrectomy systems has improved the rate of visual recovery following surgery. Ocriplasmin, by degrading laminin and fibronectin at the vitreoretinal interface, may allow induction of PVD in a non-invasive manner. Indeed, clinical studies have supported its use as an alternative to surgery in certain patient populations. However, further research is still needed with respect to greater understanding of the pathophysiology underlying the development of VMT and IMH.
