Approximately what percentage of heart attacks are preceded by diagnosed angina?

  1. 5%

  2. 20%

  3. 50%

  4. 75%

The correct answer is: 20%

Diagnosed angina, which refers to chest pain or discomfort due to myocardial ischemia, serves as an important warning sign of potential heart complications. Studies indicate that around 20% of heart attacks are preceded by a diagnosis of angina. This figure underscores the significance of angina as a symptom that can help in identifying individuals at high risk for coronary artery disease and subsequent myocardial infarctions. Recognizing and addressing angina effectively can lead to preventative measures and optimized management, ultimately helping to reduce the incidence of heart attacks among those affected.
