Angioplasty is considered superior to fibrinolytic therapy in acute myocardial infarction (AMI) if the patient receives it within the therapeutic window. It is unclear if such advantages are available for patients who need to travel from a community hospital to a facility where invasive care is available, since primary thrombolysis often re-establishes coronary artery blood flow in patients with ST elevation acute myocardial infarction (STEMI). At the most severe end of the range of acute coronary syndromes is ST - segment elevation myocardial infarction (STEMI), which generally occurs when a fibrin-rich thrombus fully occludes an epicardial coronary artery. The diagnosis of STEMI is based on clinical features and persistent ST-segment elevation as evidenced by 12 - lead electrocardiography. Patients with STEMI should have a quick reperfusion treatment evaluation and a reperfusion strategy should be performed immediately following contact with the system. All patients with AMI who had chest pain within 12 hours were evaluated. The detailed history of chest pain, character, and radiation, had been taken in terms of duration from the beginning of chest pain in minutes. After 10 minutes, patients were given 10 mg of sublingual isosorbide dinitrate and repeated ECG. Patients were excluded if chest pain or ST elevation was resolved after 10 minutes of nitrate administration. In the analysis only those cases in which chest pain and ST shift were not resolved following sublingual nitrates. Serum CKMB estimates have been performed. All patients were treated with 1.5 million IU streptokinase in 100 ml of normal saline for more than 45 minutes. Clinical assessment for 2 hours every half hour was done to evaluate: 1. Chest pain reduction in a subjective scale percentage and to assess changes in the Killip class. 2. Continuous ECG monitoring of reperfusion rhythm occurrences. Patients are assessed at the end of 2 hours of follow-up for: a. Percentage reduction in subjective chest pain a. A 12 lead ECG to identify changes in the ST height c. Repeat CK-MB estimate. Patients with thrombolysis were classified into two classes on the basis of presence or absence of SCR at the end of two hours of initiation. Those with successful reperfusion were grouped into the SCR Group and into the SCR (negative) Group without successful reperfusion. Coronary prognostic index is a set of questionnaires which prognosticate the outcome in AMI. This review describes the role of Coronary Prognostic Index and thrombolysis in patients of STEMI.
