Objective: To find outthe frequency of cardiogenic shock in patients with ACS

Study design: Cross sectional study

Methodology:A calculated sample of 240 patients presented with acute coronary syndrome confirmed clinically and/or on the basis of ECG and cardiac markers was taken. In addition to collecting basic demographic details patients were inquired about the presence of risk factors (smoking status, diabetesand hypertension).The collected data was entered and analyzed by using SPSS version 16. Quantitative variable were presented in the form of mean, range and standard deviation.

Results:Out of 240 patients, 33 patients (13.8%) were having cardiogenic shock and 207 patients (86.2%) were not. In the patients presented with cardiogenic shock, there were 21 (8.8%) with STEMI, 10 (4.2%) with NSTEMI and 2 (0.8%) with unstable angina. In STEMI there were 14 patients (5.8%) with anterior wall MI, 4 patients (1.7%) with inferior wall MI and 3 patients (1.2%) with lateral wall MI.

Conclusion:Frequency of cardiogenic shock in patients presented with ACS was 13.8%. It was more commonin patients presented with ST-segment elevation MI as compared to unstable angina and NSTEMI. In STEMI, anterior wall was more involvement was more predominant.
