Effect of Information/Knowledge/Attitude/Practice Theory-Based Progressive Rehabilitation Care on the Risk of Lower Extremity Deep Venous Thrombosis and Nutritional Status of Patients Undergoing Percutaneous Coronary Intervention for Coronary Heart Disease

Coronary heart disease is one of the cardiovascular disorders with a high risk of morbidity and mortality among older adults. Percutaneous coronary intervention is the most effective treatment for coronary heart disease. However, there are substantial safety concerns for postoperative lower -extremity deep venous thrombosis and nutrient loss. Herein, we randomly divided 112 patients with coronary heart disease into an experimental group who received progressive rehabilitation nursing care based on the information/knowledge/attitude/practice theory and a control group who received conventional nursing care. We found that the experimental group had a lower incidence of deep venous thrombosis, better cardiac function, enhanced physical fitness, and nutritional status than the control group after nursing care. Moreover, we observed better self -care ability, quality of life, and higher nursing satisfaction in the experimental group than in the control group. We demonstrated the importance of information/knowledge/attitude/practice theory -based progressive rehabilitation care in providing a more reliable safety guarantee for deep venous thrombosis and nutritional status for patients with coronary heart disease after percutaneous coronary intervention, as recommended in clinical practice.
