In the case of a STEMI (ST-Elevation Myocardial Infarction), timely intervention is crucial to restore blood flow to the heart muscle. If treatment is delayed or not provided, the heart muscle continues to be deprived of oxygen, leading to significant damage. This can precipitate various complications, with sudden cardiac arrest being one of the most severe outcomes.

Sudden cardiac arrest occurs when the heart stops beating effectively, often as a result of the electrical system of the heart failing due to severe ischemia or ventricular fibrillation. The risk of this catastrophic event rises significantly when immediate reperfusion therapies, like percutaneous coronary intervention or thrombolysis, are not administered promptly. Thus, the likelihood of sudden cardiac arrest increases dramatically if interventions are delayed in STEMI cases, underscoring the critical nature of immediate care in minimizing the risks associated with myocardial infarctions.

Other outcomes, such as complete recovery, hospitalization for additional treatments, or long-term medication management, can still occur under various circumstances but typically follow the successful intervention of a STEMI rather than being the direct result of a lack of intervention. In a scenario where care is not provided in a timely manner, sudden cardiac arrest becomes the predominant risk.
