Early percutaneous coronary intervention means performed coronary intervention between 3-24 hours after successful fibrinolytic therapy.

Delay percutaneous coronary intervention means received coronary intervention >24 hours to 2 weeks after successfully fibrinolytic therapy.

We randomized the patients into two groups early (≤ 24 hours) and delay group (> 24 hours) All patients received fibrinolysis, aspirin 300 mg and clopidogrel (300 mg for participants 75 years of age or younger or 75 mg for participants older than 75 years of age). Patients older than 75 years of age did not receive enoxaparin.

Patients will be randomly assigned to either the group that received routine early PCI (hereinafter termed the early-PCI group) or the group that received standard treatment (PCI performed after 24-72 hours of successfully fibrinolysis). Randomized will perform within 24 hours after successful fibrinolytic therapy. PCI will be performed when persistent occlusion or substantial stenosis of the infarct-related artery (either stenosis of 70% or more of the diameter of the artery or stenosis of 50-70% with thrombus, ulceration, or spontaneous dissection) was present. In case of multivessel disease, only culprit lesion will be correct.

Composite outcomes included of death, re-infarction, recurrent ischemia, re-hospitalized with ACS and worsening heart failure at 30 days for short- and 6 months for long-term outcomes.

Death was defined as all cause of death (cardiac and non-cardiac cause). Recurrent MI 'Incident MI' is defined as the individual's first MI. Re-infarction The term of 're-infarction' is used for an acute MI that occurs within 28 days of an incident- or recurrent MI.

Re-hospitalized with ACS was defined as re-admission after discharge from hospital with acute coronary syndrome composed with clinical chest pain, rising of cardiac enzymes and dynamic ST-segment change.

Re-hospitalized with heart failure was defined as re-admission after discharge from hospital with clinical decompensated heart failure.
