Key result
Type A behavior shows no overall mortality link but social isolation is associated with ~305% higher mortality.

Social isolation was associated with higher mortality in Type A men; hypothesis-generating for targeted support interventions, pending prospective confirmation.

Does social isolation predict 10-year mortality in middle-aged male cardiac patients with Type A behavior?
Absolute Event Rate: 24% vs 22%
Social isolation is a strong independent predictor of 10-year mortality in middle-aged male cardiac patients with Type A behavior, suggesting social support may mediate the cardiovascular benefits of Type A modification programs.
Orth‐Gomér et al. (1990) conducted a cohort in Cardiac disease (n=150). Type A behavior vs. Type B behavior was evaluated on 10-year mortality. Type A behavior was not associated with increased 10-year mortality compared to Type B (24% vs 22%), but socially isolated Type A men had significantly higher mortality than socially integrated Type A men (69% vs 17%, p<0.05).
