- 基于第一个COPD恶化或资格日期的定义指数日期.
- 通过链接医院数据识别心血管事件 (急性冠状动脉综合征,心律失常,心力衰竭,缺血性中风,肺高血压),采用调整后的考克斯回归模型.
主要成果:
- 这项研究包括213,466名患者;146,448人经历了恶化 (119,124人中度,27,324人严重).
- 在任何恶化后 (1-14天;aHR 3.19) 立即观察到心血管相对比率的显著增加,持续超过一年 (aHR 1.84).
- 严重恶化的风险在事件发生后1-14天是最高的 (aHR 14.5),而中度恶化的风险在14-30天后达到顶峰 (aHR 1.94);在严重恶化后,心律失常和心力衰竭的直接影响最大.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

2.8K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
