What is the cause of angina? 

The correct answer is 'Insufficient blood reaching the heart muscles.'

Key Points

• Insufficient blood reaching the heart muscles:
  • Angina is a condition marked by severe chest pain, often spreading to the shoulders, arms, and neck, caused by an inadequate blood supply to the heart.
  • This insufficient blood flow is typically due to narrowed or blocked coronary arteries, which reduce the oxygen supply to the heart muscle.
  • Symptoms of angina can include chest pain, discomfort, and pressure that may mimic the sensation of indigestion.
  • It is often triggered by physical exertion, stress, or exposure to cold, which increase the heart's demand for oxygen.
  • Treatment for angina can include lifestyle changes, medications, and in severe cases, surgical procedures like angioplasty or coronary artery bypass grafting.

Additional Information

• Insufficient blood reaching the lungs:
  • This condition is related to lung diseases such as pulmonary embolism or pulmonary hypertension, not angina.
  • It affects the ability to oxygenate blood properly but does not directly cause the chest pain associated with angina.
• Insufficient blood reaching the brain:
  • This condition can lead to strokes or transient ischemic attacks (TIAs), which present with symptoms like sudden numbness, confusion, or difficulty speaking.
  • It is not related to the chest pain characteristic of angina.
  • Insufficient blood reaching the leg muscles:
    • This condition is known as peripheral artery disease (PAD), which causes leg pain, especially during walking or exercise.
    • While PAD indicates poor blood circulation, it is not the cause of angina
