Risk Factors of Haager et al for Mortality After Percutaneous Transluminal Coronary Angioplasty for Acute Myocardial Infarction

Description

Haager et al reported risk factors for cumulative mortality after percutaneous transluminal coronary angioplasty (PTCA) performed for acute myocardial infarction. These can help to identify a patient who may benefit from more aggressive management. The authors are from University Hospital RWTH in Aachen.

Patient selection: percutaneous transluminal coronary angioplasty (PTCA)

Outcome: cumulative mortality (30-day and long-term)

Parameters:

(1) age in years

(2) heart rate prior to PTCA in beats per minute

(3) left bundle branch block (LBBB)

(4) number of ECG leads with ST-segment elevation after PTCA (persistent)

(5) myocardial blush grade (MBG, indicative of poor perfusion)

Parameter	Finding	Odds Ratio for Mortality
age in years	<= 7 years	1
	> 7 years	3.87
heart rate	<= 100 beats per minute	1
	> 100 beats per minute	4.68
LBBB	no	1
	yes	3.36
ST-segment elevation	0 to 2	1
	3 or more	3.61
MBG	0 or 1	2.17
	2 to 3	1

The risk of mortality increases with the number of risk factors present.
