Abstract

Coughing is a multifactorial symptom which could be cardiogenic or non-cardiogenic in origin. Cardiac cough is a condition seen in cardiac patients with cardiomegaly where the left atrial enlargement and compression of the main stem bronchus result in cough and subsequently tracheal collapse (TC). Numerous researchers reported cough-induced complications affecting the trachea but the aetiology of TC is poorly understood. Hence, this study aimed to study the impact of coughing on the dynamic changes of the trachea in cardiac patients. Thirteen cardiac patients and three healthy dogs were recruited in this study. Fluoroscopic examination was performed in each patient at cervical to thoracic region in standing position and the fluoroscopic images were evaluated to identify the dynamic changes of the trachea at cervical, thoracic inlet, intrathoracic and carinal regions. The percentage change of the tracheal diameter was calculated and graded. The result showed that a more severe TC was observed in coughing cardiac patients (n=5) compared to non-coughing cardiac patients (n=8). In coughing cardiac patients, the mean grade of TC was Grade IV (98.31%) at carina, Grade II (48.24%) at intrathoracic, Grade II (32.91%) at thoracic inlet and Grade I (8.31%) at cervical region. While in non-coughing cardiac patients, the mean grade of TC was Grade II (26.44%) at carina, Grade I (14.57%) at thoracic inlet, Grade I (6.17%) at intrathoraic, and Grade I (5.96%) at cervical region. Cervical lung herniation (CLH) was observed in 3 coughing patients and 1 non-coughing patient, and tracheobronchomalacia was observed in one patient. In conclusion, the dynamic changes of trachea are influenced by coughing in cardiac patients.
