About

The goal of this observational study is to analyze the acute effects of meteorological factors and air pollution on cardiovascular system. The main question it aims to answer is:

1. How do meteorological factors and air pollution affect cardiovascular system?
2. What is the interaction between meteorological factors and air pollution on cardiovascular system?

Participants will:

1. Provide their health data obtained in physical examination, including but not limited to blood pressure, blood routine, urine routine and B-ultrasound.
2. agree that the research team will use their personal identification number, gender, age, education level and other information for statistical analysis of the data.

Full description

The collected data include: ID number (or unique identification code similar to ID number), physical examination date, work unit, occupation, gender, age, systolic blood pressure, diastolic blood pressure, height, weight, blood routine, urine routine and blood biochemical examination results,Color Doppler (or B-ultrasound) examination results (thyroid color Doppler, abdominal color Doppler, urinary color Doppler, cardiac color Doppler, cervical vascular color Doppler, etc.), electrocardiogram, cardiac CTA, carbon 13 breath test, and written diagnosis results of liver fibrosis.
