[Myocardial infarct promoting type A behavior--an attempt to modify stress-inducing behavior]

Area of Science:

• Behavioral Medicine
• Cardiology
• Psychology

Background:

• Type A behavior pattern is a key factor in coronary-prone behavior and stress reactions.
• Modifying Type A behavior is crucial for cardiac patient rehabilitation and risk factor reduction.

Purpose of the Study:

• To investigate the effectiveness of behavior therapy in modifying Type A behavior patterns in cardiac patients.
• To assess the impact of psychological training on stress reactions in post-MI patients and smokers.

Main Methods:

• An experimental study involving 91 participants: 49 recent myocardial infarction (MI) patients and 42 smokers.
• Type A/B behavior patterns were assessed. A trial group received psychological training (stress management, relaxation, self-control) during rehabilitation.
• Control groups (MI patients and smokers) did not receive training. Psychological and physiological parameters were measured at multiple time points.

Main Results:

• The MI group had a significantly higher prevalence of Type A individuals (80%) compared to the smoker control group (48%).
• The trial group demonstrated significant reductions in mental and psychovegetative stress reactions compared to control groups.
• These improvements were sustained for at least 3 months post-intervention.

Conclusions:

• Behavior therapy is effective in modifying Type A behavior and reducing stress in cardiac patients.
• Psychological interventions can lead to lasting positive changes in stress responses for cardiovascular health.
• Targeting Type A behavior through therapy is a valuable component of cardiac rehabilitation programs.
