Coronary artery disease presenting with left upper quadrant pain in a patient with chronic cervical tetraplegia.

Abstract

This single-subject case report aims to describe and discuss a case of a patient with established C5 tetraplegia with acute coronary syndrome presenting with left upper quadrant pain and tenderness. A 65-year-old male with chronic C5 American Spinal Injury Association Impairment Scale (AIS) A tetraplegia presented to the emergency department with severe left upper quadrant pain radiating across the chest to the right upper limb with associated dyspnoea and diaphoresis. Prior to his emergency department admission, he had experienced progressive worsening of left upper quadrant pain and tenderness over several months. He was a non-smoker and swam regularly. He underwent coronary angiography and was found to have significant coronary artery disease. Drug-eluting stents were placed to critical coronary artery lesions followed by an uneventful hospital course with complete symptom resolution and discharge home. Patients with tetraplegia are known to have higher rates of cardiovascular disease compared to ambulatory patients. Their cardiovascular risk profile may include atypical risk factors, for example, sleep disordered breathing, relative immobility and autonomic dysfunction. A high index of suspicion for cardiac pathology is warranted in those with cervical tetraplegia with persistent 'atypical' symptoms, including within the abdomen (especially when no specific abdominal organ dysfunction is evident). Sleep apnoea and significantly impaired mobility are potential cardiac risk factors in this patient group and should alert the emergency physician to cardiac disease (as in this case) irrespective of their complex past medical history and symptomatology.
