Troponin and non-traumatic subarachnoid haemorrhage

Introduction: Subarachnoid haemorrhage (SAH) is a devastating event, with a mortality of up to 50%. Acute cardiac dysfunction is common after such an event, and it is known to have a negative impact on the outcome of these patients. Cardiac troponin release occurs frequently after SAH and represents an early biomarker for neurogenic cardiac dysfunction. Objective: The present study aimed to evaluate the impact of a raised troponin value on the outcome of SAH patients. Methods: This is a prospective observational study held between 2014-2017 at the University Emergency Hospital, Bucharest. Data on clinical admission status, high-sensitivity troponin I, ECG and echocardiographic evaluation results, ICU length of stay and in-hospital mortality rate. Statistical analysis was performed using non-parametrical Mann-Whitney and chi-square tests. The results were considered significant at p
