Total serum protein predicted mortality in patients with st-elevation myocardial ınfarction who underwent primary percutaneous coronary ıntervention: Results of 8-year follow-up

Abstract

Objectives: ST-elevation myocardial infarction (STEMI) is globally one of the leading causes of mortality. Determining modifiable mortality predictors to improve outcomes is critical. Total serum protein (TSP) is a composite indicator of immunity, nutrition, and inflammation and it plays a vital role in biological pathways contributing to cardiovascular diseases. TSP level has not been evaluated in patients with STEMI in the prediction of mortality previously. Materials and Methods: The patients diagnosed with STEMI between March 2007 and May 2009 were included in the study. TSP was obtained at admission to the hospital. Follow-up period of the study was 8 years and primary endpoint was all-cause mortality. Participants were separated according to the presence of mortality and clinical parameters compared between these two groups. Results: The mean age of the total 99 patients was 61±12.4 years and 82 (82.8%) of them were male. While left ventricular ejection fraction (LVEF) (p=0.001), serum albumin (p=0.014), and TSP (p<0.001) were lower, serum creatinine was higher (p=0.003) in the mortality group. Diabetes mellitus (p=0.007), increased age (p=0.027), LVEF (p=0.006), serum creatinine level (p=0.023), and TSP (hazard ratio: 0.159, 95% confidence interval: 0.062-0.408, p<0.001) predicted mortality independently. Conclusion: TSP level predicted all-cause mortality independently in STEMI patients who underwent primary percutaneous coronary intervention during 8-year follow-up
