Regimen compliance two years after myocardial infarction

Area of Science:

• Cardiovascular Nursing
• Health Psychology
• Patient Adherence Research

Background:

• Myocardial infarction (MI) patients require long-term adherence to complex regimens for optimal recovery and secondary prevention.
• Understanding factors influencing long-term regimen compliance, including psychosocial elements and nursing interventions, is crucial for improving patient outcomes.
• Previous research indicates variable success in improving MI patient adherence through interventions.

Purpose of the Study:

• To investigate the long-term effects of a nursing intervention initiated 30 days post-MI on regimen compliance.
• To examine the influence of patients' intentions, attitudes, and perceived beliefs of others on regimen compliance at two years post-MI.
• To identify predictors of long-term adherence to activity, stress, medication, diet, and smoking cessation regimens.

Main Methods:

• A five-phase, two-year study involving 51 myocardial infarction patients (29 experimental, 22 control).
• Comparison of regimen compliance (activity, stress, medication, diet, smoking cessation) between an experimental group receiving a nursing intervention and a control group.
• Statistical analysis to determine the predictive power of intentions, attitudes, and perceived beliefs of others on regimen compliance.

Main Results:

• No significant differences in compliance to activity, stress, or medication regimens between groups.
• The experimental group showed significantly higher compliance with the diet prescription compared to the control group.
• The control group demonstrated significantly greater compliance with smoking cessation than the experimental group.
• Perceived beliefs of others significantly predicted compliance across all regimen types at two years post-MI.
• Patient attitude was a significant predictor of compliance with diet, smoking, and stress regimens.

Conclusions:

• A nursing intervention initiated at 30 days post-MI had limited impact on overall long-term regimen compliance.
• Psychosocial factors, specifically perceived beliefs of others and personal attitudes, are strong predictors of sustained adherence in myocardial infarction patients.
• Future interventions should consider targeting social influences and modifying patient attitudes to enhance long-term regimen compliance.
