摘要Background Heart failure(HF)is a chronic,impactful condition on individuals and healthcare systems,requir-ing management that goes beyond inpatient care.This study investigated the impact of cardiovascular specialist nurses on long-term health outcomes and patient satisfaction in HF outpatient care.Methods In a year-long obser-vational study from July 2021 to July 2022,230 HF patients at our hospital were divided into an experimental group(n=115)receiving care from cardiovascular specialist nurses and a control group(n=115)managed by general nurs-ing staff.The interventions included comprehensive care such as patient education,medication management,life-style guidance,symptom monitoring,and psychological support.The major adverse cardiovascular events(MAC-Es)and rehospitalization rates were applied as the primary endpoints.Results The experimental group demon-strated significantly fewer MACEs and lower rehospitalization rates compared to the control group(P＜0.001).Higher patient satisfaction was observed in the experimental group,with 81.7％reporting high satisfaction vs.53.9％in the control group(P＜0.001).Differences in incidence of myocardial infarction and death rates between the groups were not statistically significant.Conclusions The involvement of cardiovascular specialist nurses in HF outpatient care significantly enhances clinical outcomes and patient satisfaction.These nurses play a key role in bridging the transition from hospital to home care,improving adherence to treatment regimens,and reducing health-care system burdens.
