   Abstract 


We report a case of a young woman with no cardiac history who presented with out-of-hospital cardiac arrest and ST-segment elevation on the electrocardiogram. The cardiac arrest initially was suspected to be secondary to coronary artery disease. Further history was taken from a relative who said that the patient had a severe headache before the cardiac arrest. It was subsequenly found on computed tomography of the head that the patient had infratentorial subarachnoid hemorrhage and diffurse brain edema. The management of course was totally different from what was contemplated initially.
This case illustrates that ST-segment elevation can be caused by other conditions besides on occlusive thrombus in the coronary arteries.

   Introduction Top


Patients who survive out-of-hospital cardiac arrest (OHCA) usually have ischemic electrocardiogram (ECG) changes. ST-segment elevation (STE) in these patients usually indicates acute coronary syndrome as a likely cause. Acute ST-segment changes have been associated with other noncardiac causes including acute brain attack. Moreover, the associated acute ECG changes in case of acute subarachnoid hemorrhage could range from 27% to 100% of the cases.[1],[2]


   Case Presentation Top


We report a case of a 42-year-old married woman who was normally quite fit and well. She was an intermittent smoker with no other cardiovascular risk factors. While she was in a meeting, she collapsed to the floor, and bystanders started cardiopulmonary resuscitation (CPR) for 4–5 min.

On arrival of the ambulance, she was in cardiac arrest with pulseless electrical activity (PEA) rhythm. She was immediately intubated, and a mechanical chest compression device (LUCAS™ device) was commenced. She had return of spontaneous circulation (ROSC) after 15 min. A 12-lead ECG in the ambulance showed ST elevation [Figure 1]. Therefore, she was transferred directly to our heart institute for possible primary percutaneous coronary intervention (PPCI).

On arrival to the hospital, she had further PEA arrest and CPR was commenced. There was no further detailed history of the event available at that time. After a brief CPR, she had ROSC, and the ECG confirmed ST-segment elevation in lateral leads with reciprocal changes in inferior leads [Figure 2].

Based on the available information including ECGs and cardiac arrest, a provisional diagnosis of acute STE myocardial infarction was made, and we started preparation for the PPCI procedure.

While a nasogastric tube was being inserted for medications, the husband and other family members arrived to the hospital. On discussion with the family and a brief relevant history, we found that the patient had asked for two tablets of pain killer for headache (acetaminophen) and then she collapsed.

Since the new information became available, we decided to do an urgent computed tomography (CT) head before the PPCI and withholding loading dose of antiplatelets. The CT head was arranged urgently, and the result came with an extensive supra- and infratentorial subarachnoid hemorrhage and diffuse brain edema [Figure 3]. Hence, the cardiac procedure was canceled, and the patient was immediately transferred to neurosurgical intensive care unit. The prognosis was grave and she did not survive this catastrophic event.

   Discussion Top


OHCA and ST-segment elevation on ECG is usually attributed to acute coronary syndrome and warrants urgent intervention. Usually, these patients are rushed to cath lab for urgent intervention and receive anticoagulation.

Hemorrhagic stroke can mimic morphological ECG changes in ACS with STE and can present with cardiac arrest. However, it has a totally different management and intervention. Antiplatelets and anticoagulation are absolute contraindications. Therefore, all additional information should be collected as much as possible, and a CT of brain should be considered before coronary intervention despite ST-segment elevation to avoid misdiagnosing another fatal disease with totally different management.


   Conclusion Top


The collection of all possible and relevant data is a must for proper diagnosis and management even if the initial diagnosis seemed clear at first glance. History and physical examination are musts despite advanced technology.
