Background: Patients with spinal cord injuries (SCIs) are at a greater risk for the development of cardiovascular diseases (CVDs) than able-bodied individuals due to the high risk of endothelial dysfunction. Summary: For instance, patients with SCIs lose autonomic control of the heart and vasculature, which results in severe fluctuations in blood pressure. These oscillations between hypotension and hypertension have been shown to damage blood vessel endothelial cells and may contribute to the development of atherosclerosis. Furthermore, the loss of skeletal muscle control results in skeletal muscle atrophy and inward remodeling of the conduit arteries. It has been shown that blood vessels in the legs are chronically exposed to high shear, while the aorta experiences chronically low shear. These alterations to shear forces may adversely impact endothelial vasodilatory capacity and promote inflammatory signaling and leukocyte adherence. Additionally, microvascular endothelial vasodilatory capacity is impaired in patients with an SCI, and this may precede changes in conduit artery endothelial function. Finally, due to immobility and a loss of skeletal muscle mass, patients with SCIs have a higher risk of metabolic disorders, inflammation, and oxidative stress. Key Messages: Collectively, these factors may impair endothelium-dependent vasodilatory capacity, promote leukocyte adhesion and infiltration, promote the peroxidation of lipids, and ultimately support the development of atherosclerosis. Therefore, future interventions to prevent CVDs in patients with SCIs should focus on the management of endothelial health to prevent endothelial dysfunction and atherosclerosis.

Background: In part one of this two-part series, we performed a detailed analysis of the hemodynamic signature produced during resistance exercise (RE) and discussed the subacute effects on short-term modulation of…
Background: The cardioprotective benefits and prognostic significance of regular moderate-to-vigorous physical activity (PA), increased cardiorespiratory fitness (CRF), or both are often underappreciated by the medical…
Background: Engaging in habitual resistance exercise training (RET; also known as strength training) causes systemic health effects beyond those caused by aerobic/endurance exercise training alone. Despite the…
Aortic stiffness increases with age and is a robust predictor of cerebrovascular events and cognitive decline including Alzheimer's disease and other forms of dementia. Recent clinical studies have investigated the…
Introduction: The cardio-ankle vascular index (CAVI) is a well-known index to evaluate arterial stiffness and predict cardiovascular risk. Methods: We investigated whether CAVI can predict severity and extent of…
The doctor-patient relationship is central to the practice of medicine and is essential for the delivery of high-quality health care in the diagnosis and treatment of diseases. The patients must have confidence in the…
Diabetes may induce multiple organ damage; therefore, early detection of individuals at high-risk of incident diabetes is important for timely risk assessment and intervention. Arterial stiffness (AS) occurs as a result…
Carotid stiffening is considered an important element in the pathogenesis of cerebrovascular diseases. These include stroke as well as vascular dementia and depression. However, results of individual studies evaluating…
