Abstract

OBJECTIVE:

To determine the outcomes of primary percutaneous coronary intervention for ST elevation myocardial infarction complicated by cardiogenic shock.

METHODS:

The retrospective study was conducted at the Tabba Heart Institute, a private-sector facility in Karachi. It reviewed the medical records of 56 consecutive patients between January 2009 and June 2011 with acute ST elevation myocardial infarction complicated by cardiogenic shock and subjected to primary percutaneous coronary intervention. The primary end point was in-hospital mortality and its predictors. SPSS 14 was used for statistical analysis.

RESULTS:

The mean age of the study patients was 63 +/- 11.7 years; 38 (68%) were male; 32 (57%) were hypertensive; and 39 (69%) were diabetic. Most infarcts were anterior in location (n = 36; 64%). Besides, 33 (59%) required ventilatory support. Intra-aortic balloon pump was placed in 30 (54%), and 33 (59%) patients had multivessel coronary artery disease. In-hospital mortality occurred in 26 (46%). Multivariate logistic regression analysis showed that age > 60 years (p < 0.05), diabetes (p < 0.01) and left ventricular ejection fraction < 40% (p < 0.01) were independent predictors of in-hospital mortality.

CONCLUSIONS:

Results emphasise the need of aggressive management of patients with cardiogenic shock utilising primary percutaneous coronary intervention as a reperfusion strategy to improve clinical outcomes.
