RESUMEN
OBJECTIVES: The objective of this study was to assess the prognostic value of the Model for End-stage Liver Disease (MELD)-XI score in patients undergoing PMVR with the MitraClip system. BACKGROUND: MELD-XI score, which was originally developed for prognostic assessment in patients with advanced liver disease, has been reported as a predictor of outcome in heart failure patients. METHODS: A total of 192 consecutive patients undergoing percutaneous mitral valve repair (PMVR) were included into final analysis. MELD-XI score was calculated on the day of the procedure and patients were categorized into three groups based on MELD-XI score and compared with regards to clinical characteristics and outcomes following PMVR. RESULTS: MELD-XI > 12 was associated with male gender, higher logistic EuroSCORE, reduced left ventricular ejection fraction, enlarged right ventricular end-diastolic diameter, degree of mitral regurgitation, increased NT-proBNP serum levels and elevated right atrial pressures. Youden-Index revealed a cutoff of 16 in the MELD-XI score as best predictor of one-year all-cause mortality. Kaplan-Meier analysis and the log-rank test confirmed increased one-year mortality in patients with critically high score above 16 (mortality MELD-XI score > 16 vs 16-12 vs <12:39% vs 9%. vs 15%; P = 0.005). Compared to patients with lower MELD-XI score, these patients exhibited a more than 3-fold increased one-year mortality after PMVR. CONCLUSION: Given the high mortality in patients with a MELD-XI score > 16, these patients require a high-risk preoperative assessment and should undergo a careful discussion within the heart team for the best treatment option given the considerable one-year mortality following PMVR.

Background: Acute myocardial infarction-related cardiogenic shock (AMI-CS) still has high likelihood of in-hospital mortality. The only trial evidence currently available for the intra-aortic balloon pump showed no benefit of its routine use in AMI-CS. While a potential benefit of complete revascularisation has been suggested in urgent revascularisation, the CULPRIT-SHOCK trial demonstrated no benefit of multivessel compared to culprit-lesion only revascularisation in AMI-CS. However, mechanical circulatory support was only used in a minority of patients. Objectives: We hypothesised that more complete revascularisation facilitated by Impella support is related to lower mortality in AMI-CS patients. Methods: We analysed data from 202 consecutive Impella-treated AMI-CS patients at four European high-volume shock centres (age 66 ± 11 years, 83% male). Forty-seven percentage (n = 94) had cardiac arrest before Impella implantation. Revascularisation was categorised as incomplete if residual SYNTAX-score (rS) was >8. Results: Overall 30-day mortality was 47%. Mortality was higher when Impella was implanted post-PCI (Impella-post-PCI: 57%, Impella-pre-PCI: 38%, p = 0.0053) and if revascularisation was incomplete (rS ≤ 8: 37%, rS > 8: 56%, p = 0.0099). Patients with both pre-PCI Impella implantation and complete revascularisation had significantly lower mortality (33%) than those with incomplete revascularisation and implantation post PCI (72%, p < 0.001). Conclusions: Our retrospective analysis suggests that complete revascularisation supported by an Impella microaxial pump implanted prior to PCI is associated with lower mortality than incomplete revascularisation in patients with AMI-CS.
RESUMEN
Limited data exist on the occurrence of acute kidney injury (AKI) associated with percutaneous mitral valve repair (PMVR). The objectives of the present study were (1) to assess the prevalence of AKI after MitraClip (Abbott Vascular, Santa Clara, California) implantation, (2) to analyze the predictive factors of AKI, and (3) to evaluate the prognostic value of AKI after PMVR with a view to optimizing the management of high-risk patients. A total of 206 patients (serum creatinine [SCr] 1.3 ± 0.6 mg/dl, estimated glomerular filtration rate 55 ± 24 ml/min) who underwent PMVR were included. AKI was defined as an increase in SCr by ≥0.3 mg/dl within 48 hours or an increase in SCr by ≥1.5 times baseline. AKI was assessed during the first 5 days after MitraClip implantation. The incidence of AKI after MitraClip was 18% and none of the patients required dialysis. Age, logistic EuroSCORE, baseline renal function, N-terminal pro-B-type natriuretic peptide levels, serum glycated hemoglobin A1c, serum C-reactive protein, diuretic usage, and elevated right atrial pressure were the risk factors of AKI. Incidence of AKI was associated with poor outcome. Short-term mortality was increased (30-day mortality rate AKI vs no AKI: 18% vs 1%; p <0.001). Likewise, Kaplan-Meier analysis and log-rank test confirmed reduced long-term survival of patients with AKI (1-year all-cause mortality of patients with AKI vs patients with no AKI: 34% vs 13 %; p <0.001). In conclusion, every fifth patient experienced AKI after MitraClip implantation, which was associated with increased short-term mortality and a more than threefold increase in the risk of death 1 year after PMVR.

BACKGROUND: Over 50% of patients with symptomatic heart failure (HF) experience HF with preserved ejection fraction (HFpEF). Exercise training (ET) is effective in improving cardiorespiratory fitness and dimensions of quality of life in patients with HFpEF. A systemic pro-inflammatory state induced by comorbidities as the cause of myocardial structural and functional alterations has been proposed in HFpEF. ET modifies myocardial structure and has been related to inflammatory state. We investigated Ghrelin, related adipokines, markers of inflammation, and neuro-hormonal activation in patients undergoing a structured ET vs. usual care are with HFpEF. METHODS AND RESULTS: Ex-DHF-P was a prospective, controlled, randomized multi-centre trial on structured and supervised ET in patients with HFpEF. We performed a post hoc analysis in 62 patients from Ex-DHF-P. Ghrelin, adiponectin, leptin, IL-1ß, IL-6, IL-10, tumour necrosis factor-alpha, MR-proANP, MR-proADM, CT-proET1, and CT-proAVP were assessed to seize the impact of ET on these markers in patients with HFpEF. Thirty-six (58%) patients were female, mean age was 64 years, and median ghrelin was 928 pg/mL (interquartile range 755-1156). When stratified for high versus low ghrelin, groups significantly differed at baseline in presence obesity, waist circumference, and adiponectin levels (P < 0.05, respectively). Overall, ghrelin levels rose significantly to 1013 pg/mL (interquartile range 813-1182) (P < 0.001). Analysis of covariance modelling for change in ghrelin identified ET (P = 0.013) and higher baseline adiponectin levels (P = 0.035) as influencing factors. CONCLUSIONS: Exercise training tended to increase ghrelin levels in Ex-DHF-P. This increase was especially pronounced in patients with higher baseline adiponectin levels. Future trials are needed to investigate the effect of ET on endogenous ghrelin levels in regard to interactions with cardiac structure and clinically meaningful surrogate parameters.
