Abstract
BACKGROUND: Patients with acute coronary syndrome and impaired renal function have been shown to have high mortality. However, there is scarce literature to date addressing the impact of diabetes mellitus (DM) and renal function on clinical outcomes of ST elevation myocardial infarction (STEMI) in Taiwan. METHOD: This study enrolled 512 STEMI patients who received primary percutaneous coronary intervention. Patients were divided into 4 groups including group 1: patients without DM or CKD (nDM-nCKD); group 2: patients with DM but without CKD (DM-nCKD); group 3: patients with CKD but without DM (nDM-CKD); group 4: patients with DM and CKD (DM-CKD). Patients were also classified into four groups based on their estimated glomerular filtration rates (eGFR): stage 1 (eGFR ≥ 90 ml/min/1.73 m(2), n = 163), stage 2 (eGFR = 89-60 ml/min/1.73 m(2), n = 171), stage 3 (eGFR = 59-30 ml/min/1.73 m(2), n = 136), and stage 4 (eGFR < 30 ml/min/1.73 m(2), n = 42). The complication rates, length of hospital stay, and 30-day outcomes were analyzed. RESULTS: The patients in both the nDM-CKD group and DM-CKD group had higher incidences of hypotension, intra-aortic balloon counterpulsation use, and respiratory failure (p < 0.005). They had significantly longer hospital stay and 30-day mortality rates (p < 0.001). The patients with CKD stage 3 and 4 had longer hospital stay and higher 30-day mortality rates (p < 0.001). However, DM was not an independent factor on the length of hospital stay and 30-day mortality rates. CONCLUSIONS: STEMI patients with impaired renal function, but not DM, had significantly longer hospital stay and higher 30-day mortality rates. KEY WORDS: Chronic kidney disease; Diabetes mellitus; Mortality; Primary percutaneous coronary intervention; ST-segment elevation myocardial infarction.
