Pretty bold to try to gauge this individuals ability as a physician based on this comment.

“Cardiac arrest” simply means the heart stopped. Literally everyone who has ever died has died because their heart stopped. This is why we write the CAUSE of cardiac arrest on the death certificate: i.e. cardiac arrest secondary to myocardial infarction, hypoxia in the setting of pneumonia, acidosis and multi organ failure in the setting of sepsis.

2 of those stressors don’t result in cardiac arrest without some significant associated pathology. Stepping on a Lego block with severe coronary artery disease could potentially be the tipping point to cause a heart attack. Falling off a horse resulting in blunt cardiac injury causing a fatal arrhythmia. Autoerotic asphyxiation would cause hypoxic respiratory failure which unless reversed would result in cardiac arrest.

Dude is right. “Bronchitis” by itself would not typically cause a myocardial infarction, not unless there was severe underlying coronary disease. What would be much more likely in this case is a viral syndrome/upper respiratory infection that progressed to myocarditis which could certainly result in cardiac arrhythmia/arrest.
