A Multi-center Thai University-based Surgical Intensive Care Unit Study (THAI-SICU Study): Incidence of Acute
Introduction:
To describe the incidence, characteristics and outcomes of acute myocardial infarction (AMI) and determine risk factor(s) of AMI in THAI-surgical intensive care unit (SICU).
Material And Method:
This study was multicenter prospective cohorts study that conducted data from 9 university-affiliated SICUs in Thailand between April 2011 and January 2013. We collected and evaluated data of AMI events. The patients were followed-up for up to 28 days after admitted to the SICUs.
Results:
The overall incidence of AMI in SICU was 1.4% (66 of 4,652 patients). Non-ST elevated MI was the most common electrocardiography (ECG) presentation (75%). The common clinical sign and symptom of AMI included ECG changes (53%) and elevation of cardiac enzymes (48.5%). Patients with AMI had significantly higher 28-day mortality rate (28.8% versus 13.6%, p<0.001) than those with non-MI. The Acute Physiologic and Chronic Health Evaluation (APACHE) II scores (RR 1.04, 95% CI 1.01-1.07, p = 0.003) and age >65 year (RR 2.54, 95% CI 1.36-4.75, p = 0.003) were significant risk factors of AMI.
Conclusion:
The incidence of AMI in the SICU was uncommon but led to significantly higher mortality rates. The APACHE II score and age ≥65 year were significant predictors of AMI in SICU.

Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...
