Based on the information given in the table above, the most likely explanation for the differences in rates of ASHD between the initial examination and the yearly follow-up examination in men is:
The prevalence and incidence of ASHD increase with age in men
Case-fatality rates of ASHD are higher at younger ages in men
A classic cohort effect explains these results
The case-fatality rate in ASHD is highest in the first 24 hours following a heart attack
The initial examination measures the prevalence of ASHD, whereas the subsequent examinations primarily measure the incidence of ASHD
