Abstract
Coronary heart disease (CHD) remains a prevalent and chronic cardiovascular disorder with a persistently rising global incidence and mortality rate. This study evaluates the clinical outcomes of an internet-based continuous nursing intervention for CHD patients following percutaneous coronary intervention. A cohort of 60 CHD patients admitted to our hospital between June 2023 and April 2024 were enrolled as study subjects. Using a randomized number table method, they were allocated into a control group and an observation group, with 30 patients in each. The control group received standard care, whereas the observation group underwent an integrated dual-medical model combining internet-based support with structured continuous nursing. Comparison metrics included anxiety scores (e.g., Hospital Anxiety and Depression Scale), depression scores, SF-36 quality-of-life assessments, medication adherence, cardiac function parameters (left ventricular ejection fraction, left ventricular diastolic dysfunction), and rates of cardiovascular adverse events. Post-intervention, exhibited significant reductions in anxiety and depression scores, with the observation group demonstrating markedly lower scores than the control group (P < .05). The observation group also achieved superior SF-36 scores across all domains: physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health (P < .05). While medication adherence at 1 month showed no statistical difference between groups (P > .05), the observation group displayed significantly higher compliance at 2 and 4 months (P < .05). Cardiac function improved in both groups, with the observation group achieving greater enhancements in left ventricular ejection fraction and left ventricular diastolic dysfunction (P < .05). The dual-medical model integrating internet-based continuous nursing significantly enhances cardiac rehabilitation, optimizes medication adherence, elevates quality of life, alleviates psychological distress, and reduces cardiovascular complications in post-percutaneous coronary intervention patients.
