Prognostic Score of De Luca et al for a Patient with an ST Segment Elevation Myocardial Infarction (STEMI) Treated with Primary Angioplasty (Zwolle Score)

Purpose: To evaluate a patient undergoing a primary angioplasty following an ST-segment elevation myocardial infarction (STEMI) using the Zwolle score.

Description

De Luca et al developed a prognostic score for evaluating a patient undergoing primary angioplasty after an ST-segment elevation myocardial infarction (STEMI). This can help identify a patient at increased risk for mortality within 30 days of the procedure. The authors are from Hospital De Weezenlanden in Zwolle, the Netherlands.


Outcome: death within 30 days

 

Parameters:

(1) Killip Class

(2) TIMI flow

(3) age of the patient in years

(4) number of vessels involved

(5) anterior infarction

(6) ischemic time in hours

= SUM(points for all 6 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 16

• The higher the score the greater the risk of death by 30 days.
