Abstract Purpose The Glasgow Prognostic Score (GPS), combination of C-reactive protein (CRP) and serum albumin concentration, provides predictions of prognosis in patients with heart failure. We evaluated the GPS of patients with acute myocardial infarction (MI). Methods We investigated the prognosis of 1182 patients with acute MI in our institution. These patients were classified into three groups by GPS at admission. GPS was defined as follows: patients with both elevated CRP (>1.0mg/dL) and hypoalbuminemia (<3.5 g/dL) were allocated a score of 2, patients with only one of these biochemical abnormalities were allocated a score of 1, and patients with neither of these abnormalities were allocated a score of 0. Results Of the patients, 70.3% (n=831), 19.2% (n=227), and 10.5% (n=124) had GPS of 0, 1, and 2, respectively. In-hospital mortality of GPS 0, GPS 1, and GPS 2 were 4.7%, 18.1%, and 31.5%, respectively (p<0.0001). Relative to a GPS of 0, the hazard ratios for the readmission caused by acute decompensated heart failure (ADHF) were 3.27 (95% CI: 2.04–5.18) for a GPS of 1 and 3.62 (95% CI: 1.93–6.42) for a GPS of 2 in the age- and sex- adjusted Cox proportional hazard model. After propensity score matching, baseline characteristics were balanced, and 250 paired patients constituted GPS 0 group and GPS 1–2 group. Patients with GPS1 or 2 had a higher risk of the development of ADHF compared with patients with GPS 0 (Hazard ratio: 1.96, 95% confidence interval: 1.13–3.47, p=0.017). Conclusions The GPS, which is based on systemic inflammation, is useful for predicting the development of acute decompensated heart failure after myocardial infarction.
