Cardiac dysfunctions following spinal cord injury

摘要: The aim of this article is to analyze cardiac dysfunctions occurring after spinal cord injury (SCI). Cardiac are common complications following SCI. Cardiovascular disturbances the leading causes morbidity and mortality in both acute chronic stages We reviewed epidemiology SCI, neuroanatomy pathophysiology autonomic nervous system, sympathetic parasympathetic. SCI disruption descendent pathways from central control centers neurons, originating into intermediolateral nuclei T1-L2 segments. Loss supraspinal over system results reduced overall activity below level unopposed parasympathetic outflow through intact vagal nerve. associates significant dysfunction. Impairment mostly patients with cervical or high thoracic dysrrhythmias, especially bradycardia and, rarely, arrest, tachyarrhytmias hypotension. Specific complication dependent on period time trauma like shock dysreflexia also reviewed. Spinal occurs during phase a transitory suspension function reflexes injury. Neurogenic shock, part consists severe Autonomic appears phase, resolution, it life-threatening syndrome massive imbalanced reflex discharge above splanchnic (T5-T6). Besides all this, additional complications, such as deconditioning coronary heart disease may occur. Proper prophylaxis, including nonpharmacologic pharmacological strategies rehabilitation diminish occurrence dysfunction Each type disturbance requires specific treatment.
