True/False Questions

1. Myocardial infarctions (MI) are most commonly due to occlusion (blockage) of a coronary artery caused by atherosclerosis or following the rupture of a vulnerable atherosclerotic plaque.

  1. Myocardial infarctions cause 7.2 million deaths annually in the world population.
  2. Approximately 75% of deaths from MI occur in the populations of developing nations, typically at relatively early ages (median age ≈ 50 years).
  3. Approximately 25% of deaths from MI occur in populations of developed nations, typically at later ages (median age ≈ 65 years).
  4. The global pattern of Disability Adjusted Life Years (DALY) for MI is similar to that for coronary heart disease.
  5. The case fatality rate for MI is highest in developing nations.
  6. Case fatality from MI has declined markedly in developed nations in recent years.
  7. The incidence of MI has declined dramatically in the US population.
  8. The mortality due to MI has declined dramatically in the US population.
  9. Based on results of the INTERHEART Study, the best predictive risk factor for MI is the Apo B / Apo A1 ratio.
