Subclinical Emotional Distress Predicts 6-month Clinical Outcomes After ST-segment Elevation Myocardial Infarction

Aim: To investigate associations between subclinical distress and 6-month clinical outcomes after ST-segment elevation myocardial infarction (STEMI). Materials & methods: The case–control study involved 144 STEMI patients (72 STEMI having subclinical emotional disturbances were included to the case group and 72 STEMI individuals matched with age, sex and cardiovascular risk factors were enrolled to the control group). The primary end point was the combination of 6-month events including CV death, recurrent angina, newly diagnosed heart failure and re-hospitalization. Results: The emotional distress predicted out-hospital combined end point (odds ratio [OR] = 2.48; 95% CI: 1.12–5.33; p = 0.034). Other independent predictors of out-hospital end point were Type 2 diabetes mellitus (OR = 1.10; 95% CI: 1.02–1.23; p = 0.048), thrombolysis in myocardial infarction score <6 units (OR = 0.86; 95% CI: 0.67–0.92; p = 0.001) and the number of culprit vessels (OR = 1.19; 95% CI: 1.02–1.34; p = 0.002). Conclusion: Premorbid emotional distress independently predicted 6 month combined clinical end point in STEMI patients.
