Can a heart attack happen without chest pain?

Published: 2026-08-10

Key Takeaways

  • Up to 45% of heart attacks may be 'silent' or present with atypical mild symptoms.
  • Diabetic patients are at higher risk due to autonomic neuropathy reducing pain perception.
  • Unexplained extreme exhaustion or sudden cold sweating should never be ignored.
  • Routine Lipid Profile screening identifies silent coronary artery disease early.

Silent myocardial infarction presents without severe chest pain, presenting instead as sudden weakness, severe shortness of breath, unexplained indigestion, or jaw pain.


A "silent" heart attack is a myocardial infarction that occurs with minimal, mild, or unrecognized symptoms. Patients may mistake the discomfort for heartburn, muscle strain, or a flu-like fatigue.
