Background: Type 2 MI is caused by an imbalance in oxygen supply/demand. Little is known about the patient characteristics associated with Type 2 MI.

Objective: This study aimed to define patient characteristics of Type 2 MI.

Methods: We retrospectively studied patients older than 18 years presented to our health care facilities between 9/2011-12/2015. All patients determined to have Type 2 MI (i.e., if the patient had an elevated troponin greater than or equal to 0.05 ng/mL or diagnosis of demand ischemia) were included. We excluded those with troponin greater than 20.0 ng/mL, ST-elevation MI diagnosis, cardiogenic shock, or non-ST-elevation MI with percutaneous coronary intervention, stent placement, or coronary artery bypass surgery. Hospice discharges were also excluded. Cox proportional hazards model, Chi-squared and Fishers exact tests were used for statistical analysis for one-year mortality. Hazard ratios (HR) and associated 95% confidence intervals (CI) were also computed.

Results:A total of 21,139 patients [mean age 71+/- 16 years, females 10,565(49.9%)] fulfilled the study cohort. Univariate analysis showed that one-year mortality (28.5%) was high and associated with older age and White race (P’s

Conclusion: Patients with Type 2 MI have several common characteristics which increases their likelihood of one-year mortality and a history of CAD is somewhat protective.
