VOCs in Patients With Acute Cardiogenic Chest Pain

Application of Emergency Rapid Detection of Expiratory Volatile Organic Compounds (VOCs) in Patients With Acute Cardiogenic Chest Pain

The goal of this observation study is to compare VOCs in cardiogenic chest pain population/health conditions, to answer：Establishment and promotion of the application system of emergency rapid detection of expiratory Volatile Organic Compounds (VOCs) in patients with acute cardiogenic chest pain

1. VOCs levels were measured at baseline in healthy people, and markers of VOCs that could be used to identify acute cardiogenic chest pain were sought.
2. The relationship between abnormal VOCs (mainly aldehydes) and prognosis of patients and the correlation with Super-score for early warning of acute heart failure.
