This study has the following objective:

To identify related factors to hospital mortality in patients with ST-segment elevation acute myocardial infarction submitted to pharmacoinvasive strategy within a structured healthcare network.

Primary percutaneous coronary intervention is the main therapy for patients with ST-segment elevation acute myocardial infarction. However, a significant portion of these patients won't receive optimal treatment due to the small number of tertiary centers with interventional laboratories available for 24 hours a day, 7 days a week.

Specially in large urban centers and rural areas, where tertiary care hospitals are restricted to a specific region, alternative approaches must be developed. The pharmacoinvasive strategy has emerged as an alternative for patients admitted to primary care centers. It is based in up-front intravenous thrombolytic therapy and transfer to a tertiary center where early, systematic, coronary intervention will be performed between 3 to 24 hours after the administration of thrombolytic drugs, even in cases in which successful reperfusion was obtained.

Inclusion Criteria:

• Clinical diagnosis of ST-segment elevation acute myocardial infarction submitted to pharmacoinvasive strategy with tenecteplase.

Exclusion Criteria:

• Absence of obstructive coronary disease
• Surgical reference
• Did not undergo catheterization

The patients will be selected from primary care clinic.
