What is the clinical evidence from this study?

Study design: Cohort. Population: Ischaemic heart disease (n=5936). Intervention: Type A behaviour (Bortner questionnaire). Primary outcome: Morbidity and mortality from myocardial infarction and sudden cardiac death.

What question did this study set out to answer?

To examine whether Type A coronary-prone behaviour, measured by the Bortner questionnaire, predicts the incidence of major ischaemic heart disease events in middle-aged men.

Key result

Type A behaviour, as measured by the Bortner questionnaire, did not predict major ischaemic heart disease events in middle-aged British men over an average 6.2-year follow-up.

Why the study?

Does Type A behavior predict major ischemic heart disease events in middle-aged British men?

Population

5,936 men aged 40-59 selected at random from one general practice in each of 19 British towns

Comparison

Type A behavior vs Lower scores (less Type A behavior)

Implication

Type A behaviour should not inform IHD risk assessment in middle-aged men; leaves open validity of alternative measures or populations.

Key Points

To examine whether Type A coronary-prone behaviour, measured by the Bortner questionnaire, predicts the incidence of major ischaemic heart disease events in middle-aged men.
Prospective cohort of 5,936 men aged 40–59 randomly sampled from one general practice across each of 19 British towns.
Baseline assessment evaluated Type A behaviour via the Bortner questionnaire alongside clinical checks for pre-existing ischaemic heart disease.
Follow-up extended for a mean duration of 6.2 years to assess morbidity and mortality from myocardial infarction and sudden cardiac death.
Higher Type A scores correlated with higher baseline prevalence of chest pain and angina after adjusting for social class and age, but showed weaker links to electrocardiographic evidence and no relation to recall of a doctor's diagnosis.
Prospective follow-up demonstrated no statistically significant relation between baseline Bortner scores and the attack rate or overall incidence of major ischaemic heart disease events.

Johnston et al. (1987) conducted a cohort in Ischaemic heart disease (n=5,936). Type A behaviour (Bortner questionnaire) was evaluated on Morbidity and mortality from myocardial infarction and sudden cardiac death. Type A behaviour, as measured by the Bortner questionnaire, did not predict major ischaemic heart disease events in middle-aged British men over an average 6.2-year follow-up.
