ABSTRACT
Objective To investigate the clinical features and risk factors on outcomes of patients with cardio-renal syndrome (CRS) in surgical intensive care unit (SICU). Methods The clinical data of the patients admitted to SICU of Peking University People's Hospital from January 1st 2017 to December 31st 2017 were analyzed retrospectively, including gender, age, severity of the disease, underlying diseases, type of CRS, precipitating factors of CRS, cardiac and renal function [cardiac troponin I (cTnI), B-type natriuretic peptide (BNP), serum creatinine (SCr), glomerular filtration rate (eGFR)], outcomes [secondary outcomes, duration of mechanical ventilation, the length of ICU stay, the length of hospital stay, 28-day mortality and hospital mortality]. Patients were grouped according to CRS classification or hospitalization prognosis, the clinical features within different CRS types were analyzed, and risk factors on outcomes of the CRS patients were analysed by Logistic regression. Results 86 (7.3%) of the 1 172 patients during the study period had CRS. ①CRS clinical features CRS 1-5 type patients accounted for 24.4% (21 cases), 1.2% (1 case), 20.9% (18 cases), 1.2% (1 case) and 52.3% (45 cases) respectively, CRS type 1, 3 and 5 were the main types (i.e. acute cardiac and renal dysfunction), while type 5 CRS was the highest (i.e. organ dysfunction caused by simultaneous involvement of cardiac and renal functions secondary to systemic diseases was the most common). Baseline BNP (Z = 11.365, P =0.023), SCr peak (Z = 13.405, P = 0.009) and baseline eGFR (F = 2.648, P = 0.037) were significantly different within the CRS 5 types. The basic cardiac function of type 1 CRS patients was significantly worse than that of type 3 and type 5 CRS patients [baseline BNP (μg/L) 434.2 (187.0, 1 252.0) vs. 154.9 (66.4, 272.5), 268.5 (124.1, 486.6), both P <0.05]. The basic renal function of type 3 CRS patients was significantly worse than that of type 5 CRS patients [baseline eGFR (mL/min) 71.0±30.3 vs. 88.3±29.0, P < 0.05]. The severity of acute kidney injury (AKI) in type 3 CRS patients was significantly higher than that in type 1 and type 5 CRS patients [SCr peak (μmol/L) 285.0 (171.5, 420.6) vs. 143.0 (99.5, 213.5), 189.0 (105.5, 280.5), both P < 0.01]. There were no significant differences in gender, age, department, acute physiology and chronic health evaluationⅡ (APACHEⅡ), intraoperative blood loss, basic cTnI and SCr levels, BNP peak, AKI staging and prognostic indicators among patients with various types of CRS. ② Death risk analysis:
43 (50%) of the 86 CRS patients died during the hospital stay. Compared with the survival patients, CRS death patients were older [years old 72 (57, 80) vs. 62 (50, 73)] and had higher APACHEⅡ score [22 (17, 29) vs. 18 (15, 21)], with higher proportion of cerebrovascular disease (9.3% vs. 0). Regarding to precipitating factors of CRS, sepsis/septic shock (41.9% vs. 18.6%) and surgery stress (9.3% vs. 0) were remarkably increased in death patients. Death patients had higher cTnI and SCr peak [cTnI peak (μg/L) 1.155 (0.192, 5.125) vs. 0.122 (0.045, 0.610), SCr peak (μmol/L) 208 (143, 295) vs. 146 (101, 289)] and also high proportion of AKI stage 3 (41.9% vs. 20.9%), higher rate of secondary infection (67.4% vs. 30.2%), prolonged duration of mechanical ventilation and the length of ICU stay [hours 179 (61, 470) vs. 37 (7, 134);days 10 (4, 24) vs. 5 (2, 11)], with statistically significant differences (all P < 0.05). Logistic regression analysis showed that the elderly [odds ratio (OR) = 1.053, 95% confidence interval (95%CI) = 1.003-1.094, P = 0.010], high APACHE Ⅱscore (OR = 1.165, 95%CI = 1.057-1.285, P = 0.002), sepsis/septic shock (OR = 4.561, 95%CI = 1.351-15.391, P = 0.014) and AKI stage 3 (OR = 5.468, 95%CI = 1.457-20.530, P = 0.012) were independent risk factors for hospital death in CRS patients. Conclusions Surgical ICU patients with CRS are characterized by acute cardiac and renal dysfunction. CRS type 5 is the most common and has a high fatality rate. Age, severity of illness, sepsis/septic shock and AKI stage 3 are independent risk factors of death.
