Key result
Chronic kidney disease increased the 3-year risk of cardiac death and cardiovascular readmission in NSTE-ACS patients managed invasively (49.3% vs 28.2%; HR 1.94; 95% CI 1.12-3.27; p=0.012).

In patients with NSTE-ACS treated with an invasive strategy, the presence of chronic kidney disease is an independent predictor of long-term adverse cardiovascular outcomes.
Identifies chronic kidney disease as a major prognostic red flag in invasively managed NSTE-ACS.
Patients with chronic kidney disease (CKD) have an increased risk of adverse cardiovascular outcomes after non-ST elevation acute coronary syndrome (NSTE-ACS). However, the information available on this specific population is scarce. We evaluate the impact of CKD on long-term prognosis in patients with NSTE-ACS managed with invasive strategy. We conduct a prospective registry of patients with NSTE-ACS and coronary angiography. CKD was defined as a glomerular filtration rate <60 ml/min/1.73 m 2 . The composite primary end-point was cardiac death and non-fatal cardiovascular readmission. We estimated the cumulative probability and hazard rate (HR) of combined primary end-point at 3 years according to the presence or absence of CKD. We included 248 patients with mean age of 66.9 years, 25% women. CKD was present at baseline in 67 patients (27%). Patients with CKD were older (74.9 vs. 63.9 years; p < 0.0001) with more prevalence of hypertension (89.6 vs. 66.3%; p < 0.0001), diabetes (53.7 vs. 35.9%; p = 0.011), history of heart failure (13.4 vs. 3.9%; p = 0.006) and anemia (47.8 vs. 16%; p < 0.0001). No differences in the extent of coronary artery disease. CKD was associated with higher cumulative probability (49.3 vs. 28.2%; log-rank p = 0.001) and HR of the primary combined end-point (HR: 1.94; 95% CI: 1.12–3.27; p = 0.012). CKD was an independent predictor of adverse cardiovascular outcomes at 3 years (HR: 1.66; 95% CI: 1.05–2.61; p = 0.03). In NSTE-ACS patients treated with invasive strategy, CKD is associated independently with an increased risk of adverse cardiovascular outcomes at 3 years. Los pacientes con enfermedad renal crónica (ERC) presentan mayor riesgo de eventos adversos cardiovasculares tras un síndrome coronario agudo sin elevación del segmento ST (SCASEST). Sin embargo, la información disponible en esta población específica es escasa. Evaluamos el efecto de la ERC en el pronóstico a largo plazo de pacientes con SCASEST tratados con estrategia invasiva. Registro prospectivo de pacientes con SCASEST y coronariografía. Definimos ERC como una tasa de filtrado glomerular < 60 ml/min/1,73m 2 . La variable de valoración final fue el combinado de muerte y reingreso cardiovasculares (nuevo síndrome coronario agudo, insuficiencia cardíaca e ictus no fatales). Estimamos la probabilidad acumulada, estratificada por ERC, y la relación entre esta y la tasa de riesgo del evento combinado a 3 años. Incluimos a 248 pacientes, con media de edad de 66,9 años; el 25% eran mujeres. Los 67 casos (27%) con ERC fueron mayores (74,9 vs. 63,9 años; p < 0,0001) y con más prevalencia de hipertensión (89,6 vs. 66,3%; p < 0,0001), diabetes (53,7 vs. 35,9%; p = 0,01), historia de insuficiencia cardíaca (13,4 vs. 3,9%; p = 0,006) y anemia (47,8 vs. 16%; p < 0,0001). Sin diferencias en la extensión de la enfermedad coronaria. La ERC se asoció a mayor probabilidad (49,3 vs. 28,2%; log-rank p = 0,001) y tasa de riesgo del evento combinado (HR ajustada: 1,94; IC 95%: 1,12-3,27; p = 0,012). La ERC fue predictor independiente de eventos (HR: 1,66; IC 95%: 1,05-2,61; p = 0,03). En pacientes con SCASEST tratados con estrategia invasiva, la ERC se asocia de manera independiente a mayor riesgo de eventos cardiovasculares a 3 años.

Torres et al. (2017) conducted a cohort in Non-ST elevation acute coronary syndrome (NSTE-ACS) (n=248). Chronic kidney disease vs. Absence of chronic kidney disease was evaluated on Cardiac death and non-fatal cardiovascular readmission (HR 1.94, 95% CI 1.12-3.27, p=0.012). Chronic kidney disease increased the 3-year risk of cardiac death and cardiovascular readmission in NSTE-ACS patients managed invasively (49.3% vs 28.2%; HR 1.94; 95% CI 1.12-3.27; p=0.012).
