Abstract

Objective: To study the frequency of cardiogenic shock in patients with non-ST elevation myocardial infarction (Non-STEMI).

Methodology: This descriptive cross-sectional study was conducted from May 2011 to October 2011, at cardiology department of Hayatabad medical complex, Peshawar. Sample size was calculated using WHO sample size as 600 patients. Consecutive non probability sampling technique was used. All patients with diagnosed Non-STEMI, meeting the inclusion criteria were enrolled in the study after taking informed consent. All patients were admitted in the cardiology unit and were evaluated for cardiogenic shock on the basis of operational definitions and were managed as per ward and unit protocols. All relevant information was recorded in a predesigned proforma.

Results: Out of 600 patients, 408(68%) patients were male and 192(32%) patients were female. Mean age of the patients was 60±1.26 years and majority (n=246; 41%) of patients were in age range 61-70 years. Overall 30 (5%) patients with Non-STEMI developed cardiogenic shock. Out of 30 patients, 6 (20%) patients were in age range 51-60 years, 8 (26.7%) patients were in age range 61-70 years and 16 (53.3%) patients were above 70 years of age.  Mean time interval from onset of chest pain and ECG diagnosis of myocardial infarction was 8±2.71 hours. In patients with cardiogenic shock, 16 (53.3%) and 10 (33.3%) patients had time interval of 4-8 hours and >8-16 hours respectively.

Conclusion: Cardiogenic shock occurs in 5% patients with Non-STEMI in our set up and is more common in patients above 70 years of age.
