The effectiveness of risk-based nursing interventions in elderly patients with unstable angina pectoris
基于风险分层的护理干预在老年不稳定型心绞痛患者中的应用效果

摘要

目的 本研究基于风险分层的护理干预模式开展，通过采用风险评估量表，将老年不稳定型心绞痛患者区分为不同风险等级，并据此制定差异化的护理方案，观察其在降低不良心血管事件发生率方面的具体成效。方法 选取本院（2025年1月-2026年1月）902例患者，按照双盲法分为两组，对照组（452例）患者接受常规护理干预，观察组（450例）患者接受风险分层护理干预，详细分析不同护理模式的干预效果差异。结果 两组患者护理干预3个月后MAE发生率显示，观察组低于对照组，差异有统计学意义（p<0.05）。结论 临床采用基于风险分层的护理干预，能够根据患者个体的危险等级实施差异化管理，有针对性地优化老年不稳定型心绞痛患者的护理方案，更有效地降低不良心血管事件的发生风险，从而为患者预后带来积极影响。

Abstract

Objective This study was conducted based on a risk-stratified nursing intervention model. Using a risk assessment scale, elderly patients with unstable angina were categorized into different risk levels, and differentiated nursing plans were formulated accordingly to observe their specific effects in reducing the incidence of adverse cardiovascular events.
Methods A total of 902 patients from our hospital (January 2025 to January 2026) were selected and divided into two groups using a double-blind method. The control group (452 cases) received conventional nursing interventions, while the observation group (450 cases) received risk-stratified nursing interventions. The differences in intervention effects between the two nursing models were analyzed in detail.
Results After 3 months of nursing intervention, the MAE incidence in the observation group was lower than that in the control group, with a statistically significant difference (p<0.05).
Conclusion   Clinical implementation of risk-stratified nursing interventions enables differentiated management based on individual patient risk levels, allowing for targeted optimization of nursing plans for elderly patients with unstable angina. This approach more effectively reduces the risk of adverse cardiovascular events, thereby positively impacting patient prognosis.
