The Atherogenic Index of Plasma（AIP） in Patients With Atrial Fibrillation

Study Overview
=================
Brief Summary
-----------------
The goal of this observational study is to learn about The Atherogenic Index of Plasma(AIP) in patients with atrial fibrillation(AF). The main questions it aims to answer are: (1)To investigate the correlation between AIP and the occurrence rate of AF. (2) To investigate the correlation between AIP and the occurrence rate of cardiovascular outcome events (MACE events, heart failure, embolism events) in patients with AF. Patients's clinical data including medical history, laboratory tests, and imageological examination will be collected and further analysed.

Detailed Description
-----------------
Baseline demographic data: age, gender, height, weight, systolic blood pressure, diastolic blood pressure, smoking habit, drinking habit, physical activity, fasting blood glucose, medication use (statins, ACEI/ARB, anticoagulant related drugs), basic medical history (hypertension, diabetes mellitus, coronary heart disease).

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| atrial fibrillation (AF) | AF diagnoses were ascertained by 3 different sources in our study: ECGs performed at study visits, hospital discharge codes, and death certificates. All ECGs automatically coded as AF were visually checked by a trained cardiologist to confirm AF diagnosis. | 10 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| major adverse cardiovascular events (MACEs) | Follow up main adverse cardiovascular and cerebrovascular events such as death, myocardial infarction, stroke, and repeated revascularization. | 10 years | 
| heart failure | Patients who required intravenous medications for heart failure after admission (including diuretics, vasodilators, or inotropic agents) or a significant increase in the dose of oral diuretics (i.e., an increase in furosemide of ≥40mg or equivalent or the addition of a thiazide to a loop diuretic) were considered to have heart failure readmission. Pulmonary rales and/or the third heart sound, chest X-ray, dyspnea, peripheral edema, and NYHA grade were evaluated to further confirm the occurrence of heart failure. | 10 years |
