About this trial
This is an interventional prevention trial for ST Elevation Myocardial Infarction focused on measuring acute myocardial infarction,contrast,coronary intervention

Guideline Hydration
Adequate Hydration
No hydration for patients without chronic kidney disease(CrCl<60ml/min),or Receiving hydration with a 1 mL/kg bolus of intravenous isotonic saline (0.9% sodium chloride) after diagnosis of chronic kidney disease until 24 hours after PCI. Hydration rate was reduced to 0.5 mL/kg per hour in patients with New York Heart Association class III or KillipⅡ/Ⅲ.
Receiving hydration with a 3 mL/kg.hour bolus of intravenous isotonic saline (0.9% sodium chloride) from randomization to the end of the procedure, the measurement of LVEDP was conducted after the procedure, a sliding-scale hydration was employed in the LVEDP-guided hydration arm that was based on LVEDP for 2 hours: 5 ml/kg/hr for LVEDP <13 mmHg, 3 ml/kg/hr for LVEDP 13-18 mmHg, and >1.5 ml/kg/hr for LVEDP >18 mmHg, whereas,0.5 ml/kg/hr for LVEDP >20 mmHg, continue hydration with a 1 mL/kg until 24 hours after procedure. Hydration rate was reduced to 0.5 mL/kg per hour in patients with New York Heart Association class III or KillipⅡ/Ⅲ.
