Background: Impella was approved for mechanical circulatory support (MCS) in 2008, but large-scale, real-world data on its use are lacking. Our objective was to describe trends and variations in Impella use, clinical outcomes, and costs across US hospitals in patients undergoing percutaneous coronary intervention (PCI) treated with MCS (Impella or intra-aortic balloon pump). Methods: From the Premier Healthcare Database, we analyzed 48 306 patients undergoing PCI with MCS at 432 hospitals between January 2004 and December 2016. Association analyses were performed at 3 levels: time period, hospital, and patient. Hierarchical models with propensity adjustment were used for association analyses. We examined trends and variations in the proportion of Impella use, and associated clinical outcomes (in-hospital mortality, bleeding requiring transfusion, acute kidney injury, stroke, length of stay, and hospital costs). Results: Among patients undergoing PCI treated with MCS, 4782 (9.9%) received Impella; its use increased over time, reaching 31.9% of MCS in 2016. There was wide variation in Impella use across hospitals (>5-fold variation). Specifically, among patients receiving Impella, there was a wide variation in outcomes of bleeding (>2.5-fold variation), and death, acute kidney injury, and stroke (all ≈1.5-fold variation). Adverse outcomes and costs were higher in the Impella era (years 2008–2016) versus the pre-Impella era (years 2004–2007). Hospitals with higher Impella use had higher rates of adverse outcomes and costs. After adjustment for the propensity score, and accounting for clustering of patients by hospitals, Impella use was associated with death: odds ratio, 1.24 (95% CI, 1.13–1.36); bleeding: odds ratio, 1.10 (95% CI, 1.00–1.21); and stroke: odds ratio, 1.34 (95% CI, 1.18–1.53), although a similar, nonsignificant result was observed for acute kidney injury: odds ratio, 1.08 (95% CI, 1.00–1.17). Conclusions: Impella use is rapidly increasing among patients undergoing PCI treated with MCS, with marked variability in its use and associated outcomes. Although unmeasured confounding cannot be ruled out, when analyzed by time periods, or at the hospital level or the patient level, Impella use was associated with higher rates of adverse events and costs. More data are needed to define the appropriate role of MCS in patients undergoing PCI.

Acute kidney injury (AKI), mostly defined as a rise in serum creatinine concentration of more than 0.5 mg/dl, is a common, serious, and potentially preventable complication of percutaneous coronary intervention and is associated with adverse outcomes including an increased risk of inhospital mortality. Recent data from the National Cardiovascular Data Registry/Cath-PCI registry including 985,737 consecutive patients undergoing percutaneous coronary intervention suggest that approximately 7% experienced AKI with a reported incidence of 3–19%. In patients undergoing primary percutaneous coronary intervention for acute myocardial infarction (AMI), AKI occurs more frequently with rates up to 20% depending on patient and procedural characteristics. However, varying definitions of AKI limit comparisons of AKI rates across different studies. Recently, most studies have adopted the Acute Kidney Injury Network (AKIN) criteria for definition and classification of AKI. Beyond the AKIN criteria for AKI, other classifications such as the risk, injury, failure, loss and end-stage kidney disease (RIFLE) and kidney disease: improving global outcomes (KDIGO) criteria are used to define AKI. Notably, even small increases in serum creatinine beyond AKI may be associated with adverse outcomes including increased hospital length of stay and excess. Acute kidney injury (AKI) is a serious and potentially preventable complication of percutaneous coronary intervention (PCI). Worsening renal function is associated with adverse outcomes including a higher rate of in-hospital mortality. In patients undergoing primary PCI for acute myocardial infarction (AMI), AKI occurs up to 20% of such individuals. Varying definitions of AKI limit comparisons of AKI rates across different studies. Additionally, even small increases in serum creatinine beyond lavels meeting AKI definitions may be associated with adverse outcomes including increased hospital length of stay.

AbstractAcute kidney injury (AKI) is a common complication post-PCI. Here, in a single-center observational registry, we compared the frequency of AKI in patients at elevated risk for AKI (based on Mehran risk stratification scoring) who underwent VA-ECMO- or Impella-supported high-risk PCI. A total of 28 patients scheduled for elective high-risk PCI with mechanical circulatory support were studied prospectively. All patients were turned down for surgery due to exceedingly high risk. Allocation to VA-ECMO (n=11) or Impella (n=17) was performed according to site-specific restrictions on the daily availability of the VA-ECMO platform as a prospective enrollment and performed prior to initiation of PCI. We analyzed AKI incidence as our primary endpoint, as well as PCI success, duration, and peripheral complications. All patients were successfully revascularized and had MCS weaned at the end of the procedure. Baseline GFR and procedural contrast media were similar. Despite similar risks for AKI as calculated by the Mehran score (35 ± 18.9 vs. 31 ± 16.6 %; p=0.55), patients supported by Impella during PCI demonstrated a reduced incidence of AKI (55 vs. 12 %; p=0.03). MCS-assisted high-risk PCI with VA-ECMO or Impella is feasible. However, Impella is associated with a shorter procedure time and a lower incidence of AKI.

Background: Acute kidney injury is associated with adverse outcomes after acute ST elevation myocardial infarction (STEMI). It remains unclear, however, whether subclinical increase in serum creatinine that does not reach the consensus criteria for acute kidney injury is also related to adverse outcomes in STEMI patients undergoing primary percutaneous coronary intervention. Methods: We conducted a retrospective study of 1897 consecutive STEMI patients between January 2008 and May 2016 who underwent primary percutaneous coronary intervention, and in whom acute kidney injury was not diagnosed throughout hospitalization. We investigated the incidence of subclinical acute kidney injury (defined as serum creatinine increase of ≥ 0.1 and < 0.3 mg/dl) and its relation to a composite end point of adverse in hospital outcomes. Results: Subclinical acute kidney injury was detected in 321 patients (17%). Patients with subclinical acute kidney injury had increased rate of the composite end point of adverse in-hospital events (20.3% vs. 9.7%, p<0.001), a finding which was independent of baseline renal function. Individual components of this end point (occurrence of heart failure, atrial fibrillation, need for mechanical ventilation and in-hospital mortality) were all significantly higher among patients with subclinical acute kidney injury ( p< 0.05 for all). In a multivariable regression model subclinical acute kidney injury was independently associated with higher risk for adverse in-hospital events (odds ratio 1.92.6, 95% confidence interval: 1.23–2.97, p=0.004). Conclusions: Among STEMI patients treated with primary percutaneous coronary intervention, small, subclinical elevations of serum creatinine, while not fulfilling the consensus criteria for acute kidney injury, may serve as a significant biomarker for adverse outcomes.

Abstract Background This study aimed to investigate the connection between malnutrition evaluated by the Controlling Nutritional Status (CONUT) score and the risk of contrast-associated acute kidney injury (CA-AKI) in elderly patients who underwent percutaneous coronary intervention (PCI). Methods A total of 1308 patients aged over 75 years undergoing PCI was included. Based on the CONUT score, patients were assigned to normal (0–1), mild malnutrition (2–4), moderate-severe malnutrition group (≥ 5). The primary outcome was CA-AKI (an absolute increase in ≥ 0.3 mg/dL or ≥ 50% relative serum creatinine increase 48 h after contrast medium exposure). Results Overall, the incidence of CA-AKI in normal, mild, moderate-severe malnutrition group was 10.8%, 11.0%, and 27.2%, respectively (p < 0.01). Compared with moderate-severe malnutrition group, the normal group and the mild malnutrition group showed significant lower risk of CA-AKI in models adjusting for risk factors for CA-AKI and variables in univariate analysis (odds ratio [OR] = 0.48, 95% confidence interval [CI]: 0.26–0.89, p = 0.02; OR = 0.46, 95%CI: 0.26–0.82, p = 0.009, respectively). Furthermore, the relationship were consistent across the subgroups classified by risk factors for CA-AKI except anemia. The risk of CA-AKI related with CONUT score was stronger in patients with anemia. (overall interaction p by CONUT score = 0.012). Conclusion Moderate-severe malnutrition is associated with higher risk of CA-AKI in elderly patients undergoing PCI.
