概括
堪萨斯城心肌病问卷-12 (KCCQ-12) 有效预测心力衰竭住院和门诊病例中的死亡率. 较低的KCCQ-12分数和未完成表明更高的风险,验证其作为预后工具的使用.
科学领域:
- 心脏病学 心脏病学
- 临床结果研究研究
- 医疗保健服务研究 医疗服务研究
背景情况:
- 堪萨斯城心肌病问卷-12 (KCCQ-12) 是患者报告的心力衰竭的结果指标.
- 它在现实世界临床实践中对住院和死亡率的预测实用性并不成熟,与临床试验不同.
研究的目的:
- 评估KCCQ-12对接受门诊心力衰竭护理的患者住院和死亡率的预测价值.
- 评估KCCQ-12总体总结 (KCCQ-OS) 评分作为预后指标的表现.
主要方法:
- 一项队列研究,涉及从2019年7月到2024年3月的心力衰竭诊所的4,406名患者.
- 主要暴露:KCCQ-OS得分.主要暴露:KCCQ-OS得分. 主要结局:住院90天和累积死亡率.
- 统计分析包括后勤回归,Cox比例危险模型和机器学习 (XGBoost,随机生存森林).
主要成果:
- 在完成KCCQ-12的2888名 (66%) 患者中,观察到KCCQ-OS的中位数为59.4.
- 评分<25与90天住院 (OR:3.49) 和累积死亡率 (HR:3.09) 的调整后风险显著增加有关.
- 对于这两种结果,KCCQ-OS是机器学习模型中最重要的预测因素. 不完成也预测了更糟糕的结果.
结论:
- 在门诊心力衰竭护理中,较低的KCCQ-OS得分与住院治疗和死亡率的增加密切相关.
- 包括其未完成状态在内的KCCQ-12在常规临床实践中作为一种有价值的预后工具.
- 在关键不良事件的机器学习分析中,KCCQ-OS得分显示出占主导地位的预测能力.

Pathophysiology of Heart Failure
1.5K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Assessment of the Cardiovascular System I: Subjective Data
282
A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities

Kaplan-Meier Approach
107
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...
