2. The firefighter received a physical examination that is reasonably aligned with the national fire protection association standard on comprehensive occupational medical program for fire departments (NFPA 1582).

3. The firefighter was exposed to a known event and the heart-related, perivascular or pulmonary injury, illness or death occurred within twenty-four hours after the exposure and was reasonably related to the exposure.

2. The nonoccupational condition was diagnosed and documented before the firefighter's employment or qualifying event.

3. The nonoccupational condition was independently sufficient to cause the injury, illness or death without contribution from any of the following firefighter-related duties:

C. e. Subsection A of this section does not apply if there is evidence that the firefighter's exposure to cigarettes or tobacco products outside the scope of the firefighter's official duties is a substantial contributing cause in the development of the heart-related, perivascular or pulmonary injury, illness or death.

1. "heart-related" includes any of the following:

(a) Myocardial infarction.

(b) Acute coronary syndrome.
