Efficacy Of Eptifibatide Compared To Abciximab In Primary Percutaneous Coronary Intervention (PCI) For Acute ST Elevation Myocardial Infarction (STEMI)

Sum STR was calculated as the difference between baseline (ECG I) and ECG III. The sum STR is the segment elevation resolution from all ECG leads associated with the infarct location. ST resolution, a method used to evaluate myocardial reperfusion, was expressed as a percentage of the baseline value (Complete: ≥ 70% resolution).

Sum STR was calculated as the difference between baseline (ECG I) and ECG III. The sum STR is the segment elevation resolution from all ECG leads associated with the infarct location. ST resolution, a method used to evaluate myocardial reperfusion, was expressed as a percentage of the baseline value (Complete: ≥ 70% resolution).

Sum STR was calculated as the difference between baseline (ECGI) and ECG III. The sum STR is the segment elevation resolution from all ECG leads associated with infarct location. ST resolution, a method used to evaluate myocardial reperfusion, was expressed as a percentage of the baseline (Complete: ≥ 70% resolution; Partial: ≥ 30% and < 70% resolution; None: < 30% resolution).

Single lead STR is calculated as the difference (as a percentage) between baseline (ECG I) and ECG III of either the ST elevation on one of the leads (II, III, aVF, V5, and V6) or the ST depression of one of the precordial leads (V1- V4), whichever lead showed the largest deviation either at baseline or at ECG III, respectively (Complete: ≥ 70%; Partial: ≥ 30% and <70%).

Single lead STR is calculated as the difference between baseline (ECG I) and ECG III of either the ST elevation on one of the leads (II, III, aVF, V5, and V6) or the ST depression of one of the precordial leads (V1 -V4), whichever lead showed the largest deviation either at baseline or at follow-up, respectively. STR was expressed as a percentage from baseline.

Mean sum STR was calculated as the difference between baseline (ECGI) and ECG II: the mean of the sum of ST elevation resolution from all ECG leads associated with infarct location. ST resolution was expressed as a percentage from baseline.

Max STE is measured similarly to single-lead STR, but was not compared with the ST deviation on the baseline ECG I. It was the existing ST deviation on the single ECG lead of maximum ST deviation present at 60 minutes after the PCI (ECG III).

Number of participants with the respective patency of the infarcted vessels was evaluated by TIMI (Thrombolysis In Myocardial Infarction) flow grades (Grade 0 = No perfusion, Grade 1 = Penetration with minimal perfusion, Grade 2 = Partial perfusion, Grade 3 = Complete perfusion), as assessed by core angiography lab.

The number of participants with TIMI grade 3 (complete perfusion) patency of the infarcted vessels following PCI, as assessed by core angiography lab, was measured.

cTIMI frame counts (number of cineframes needed for dye to reach standardized distal landmarks in a coronary vessel; objective index of coronary blood flow) following PCI, as assessed by core angiography lab.

The number of participants with the indicated myocardial blush grade (TMPG), used to assess the myocardial reperfusion in the infarcted myocardium following PCI (as assessed by the core angiography laboratory), was measured. Blush grades: 0 = failure of dye to enter the microvasculature; 1 = dye slowly enters but fails to exit the microvasculature; 2 = delayed entry and exit of dye from the microvasculature; 3: normal entry and exit of dye from the microvasculature. Blush that is of only mild intensity throughout the washout phase but fades minimally is also classified as grade 3.

The number of participants who died, experienced re-MI, or experienced UTVR (necessity of re-PCI of the target vessel or coronary artery bypass graft [CABG] because of recurrent ischaemic angina within 30 days after PCI) within the specified timeframe was measured.

The number of participants who died, and/or experienced re-MI or UTVR (individually counted) within the specified timeframe was measured.

Number of participants who experienced stroke (hemorrhagic, non-hemorrhagic) or major bleedings (TIMI class: intracranial haemorrhage, spontaneous bleeding, bleeding at any instrumented site, retroperitoneal bleeding, or clinically significant overt haemorrhage associated with a drop in haematocrit of ≥ 15% or a drop in haemoglobin of ≥ 5 g/dL).

The number of participants who died and/or experienced re-MI within 6 month after PCI was measured.

The number of participants with heart failure within 6 month after PCI was measured.

Number of participants with major bleedings (according to TIMI classification: intracranial haemorrhage, spontaneous bleeding, bleeding at any instrumented site, retroperitoneal bleeding, or clinically significant overt haemorrhage associated with a drop in haematocrit of ≥ 15% or a drop in haemoglobin of ≥ 5 g/dL) within the specified timeframe was measured.

The number of participants with minor bleedings (according to TIMI classification: clinically overt bleeding [e.g., gross haematuria or haematemesis) associated with a drop in haematocrit of ≥ 9% or a drop in haemoglobin of ≥ 3 g/dL) within the specified timeframe was measured.

Costs were measured as the duration of stay in the ward (outpatient, normal ward, and intensive care unit) within the specified timeframe was measured.
