Comparison of Health Behavior Change Before and After the Percutaneous Coronary Intervention among Coronary Artery Disease Patients

Q: What are the key findings of this study?

Percutaneous coronary intervention was associated with a significant increase in patients' mean total health behavior score from 65.42±12.99 before PCI to 72.53±10.18 after PCI.

Q: What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Coronary artery disease treated with percutaneous coronary intervention (n=120). Intervention: Percutaneous coronary intervention (post-PCI status) vs. Pre-PCI status (within-subject comparison). Primary outcome: Total cardiac health behavior score (out of 96 points) (p=<.001).

Q: What does this research mean for the field?

Patients undergoing percutaneous coronary intervention demonstrate a significant overall improvement in health behaviors, particularly in health responsibility, smoking, drinking, and diet, while exercise and stress management habits show no significant change. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Q: What question did this study set out to answer?

To evaluate changes in health behaviors before and after percutaneous coronary intervention among patients diagnosed with coronary artery disease.

Key result

PCI is linked to an absolute ~7-point improvement in post-procedure cardiac health behavior scores.

Why the study?

Does undergoing percutaneous coronary intervention improve self-reported health behaviors in patients with coronary artery disease?

Key Points

To evaluate changes in health behaviors before and after percutaneous coronary intervention among patients diagnosed with coronary artery disease.
Conducted a self-administered structured questionnaire survey between May 15 and October 12, 2012, at a single university hospital in Daegu, South Korea.
Enrolled 120 patients aged 40 to 69 years who had undergone percutaneous coronary intervention between 3 months and less than 2 years prior.
Assessed 24 items on a 4-point Likert scale across five domains: health responsibility, exercise, diet habits, stress management, and smoking/drinking habits.
Total health behavior scores increased significantly from 65.42±12.99 before the intervention to 72.53±10.18 after the intervention (p<.001).
Significant improvements were observed in health responsibility (11.75±4.02 to 14.96±2.74, p<.001), diet habits (20.20±4.56 to 21.15±3.72, p=.039), and smoking/drinking habits (11.40±4.21 to 13.76±2.91, p<.001).
No significant changes occurred in exercise scores (13.20±4.21 vs 13.40±3.52, p=.561) or stress management scores (8.86±2.43 vs 9.25±1.75, p=.103).

Structured PICO

Does undergoing percutaneous coronary intervention improve self-reported health behaviors in patients with coronary artery disease?

P

Population

120 coronary artery disease patients aged 40 to 69 years (mean age 56.71, 17.5% female) at a single university hospital in South Korea, surveyed 3 months to 2 years after undergoing percutaneous coronary intervention.

E

Exposure

Post-percutaneous coronary intervention (PCI) status (3 months to <2 years after procedure)

C

Comparator

Pre-percutaneous coronary intervention status (self-reported retrospective baseline in the same patients)

O

Outcome

Total cardiac health behavior score (24 items across 5 domains, 4-point Likert scale, maximum 96 points) assessed via self-administered questionnairepatient reported

Main Result

Absolute Event Rate: 72.53% vs 65.42%

p-value: p=<.001

Although overall health behavior scores improved after PCI—particularly in health responsibility and smoking/drinking habits—practical lifestyle efforts such as exercise and stress management did not significantly change, highlighting the need for structured post-PCI patient education and cardiac rehabilitation counseling.

Limitations

Single-center study at one university hospital limiting generalizability
Detailed alcohol consumption volume was not investigated
Cross-sectional retrospective recall of pre-PCI behaviors (3 months to 2 years post-PCI)
Reduced statistical power when analyzing detailed subgroups
Single university hospital sample limiting generalizability
Did not investigate exact amount of alcohol consumption
Unclear whether behavioral changes were due to medical staff counseling or the procedure itself
Restricted to patients 3 months to 2 years post-PCI relying on recall
Lower statistical power for subgroup analyses

Implication

Observed health behavior gains after PCI are hypothesis-generating; leaves open effects of rehabilitation on exercise and stress management.

Abstract

Objectives: The purpose of this study was to investigate health behaviors of patients before and after percutaneous coronary intervention (PCI). Methods: The subjects of this study were 120 men and women whose age ranged from 40 years to 69 years among the patients who received percutaneous coronary intervention in Y university hospital that was located in Daegu city and who had diagnosed for 3 months or more and less than 2 years. Structured questionnaire was used to conduct self-administered survey from May 15 to October 12 in 2012. Results: Patients's health behavior score was ranged from 46 to 94 points after the PCI intervention. The score was <TEX>65.42±12.99</TEX> points before and significantly increased up to <TEX>72.53±10.18</TEX> points after the PCI intervention (p<.001). According to subcategory of health behavior, significant differences were found in scores of health responsibility (increased interest in health, watching of lecture on health and behavior to be punctual on counseling or medical treatment), diet, smoking, and drinking (p<.001, p=.039, p=<.001). However, no significant change was found in practice efforts such as exercise, eating habits and relaxation for stress management. Conclusions: In conclusion, it is necessary to provide education and counseling that enabling patients to improve smoking, drinking, practicing exercise and healthy eating habits.
