Objective:

To assess the effects of nursing cardiac rehabilitation on cardiac function and quality of life in individuals with coronary heart disease following PCI.

Key Findings:

• The observation group showed reduced left ventricular end-systolic and end-diastolic diameters and increased left ventricular ejection fraction post-nursing (P < 0.05).
• The observation group had a greater 6-minute walking distance compared to the control group (P < 0.05).
• Adverse cardiovascular events were less frequent in the observation group (P = 0.025).
• The observation group achieved higher WHOQOL-BREF scores across all domains (P < 0.05).
• Nursing satisfaction levels were higher in the observation group (P = 0.014).

Interpretation:

Nursing cardiac rehabilitation significantly improves cardiac performance and quality of life in CHD patients post-PCI, indicating its clinical importance.

Limitations:

• The study was conducted at a single center, which may limit generalizability.
• The sample size was relatively small with only 100 participants.

Conclusion:

Nursing cardiac rehabilitation enhances cardiac function and quality of life in CHD patients after PCI, supporting its implementation in clinical practice.
