ABSTRACT

INTRODUCTION: This study aimed to evaluate the use and dose of loop diuretics (LDs) across the entire ejection fraction (EF) spectrum in a large, 'real-world' cohort of chronic heart failure (HF) patients. METHODS: A total of 10 366 patients with chronic HF from 34 Dutch outpatient HF clinics were analysed regarding diuretic use and diuretic dose. Data regarding daily diuretic dose were stratified by furosemide dose equivalent (FDE)>80 mg or ≤80 mg. Multivariable logistic regression models were used to assess the association between diuretic dose and clinical features. RESULTS: In this cohort, 8512 (82.1%) patients used diuretics, of which 8179 (96.1%) used LDs. LD use was highest among HF with reduced EF (HFrEF) patients (81.1%) followed by HF with mild-reduced EF (76.1%) and HF with preserved ejection fraction EF (73.8%, p<0.001). Among all LDs users, the median FDE was 40 mg (IQR: 40-80). The results of the multivariable analysis showed that New York Heart Association classes III and IV and diabetes mellitus were one of the strongest determinants of an FDE >80 mg, across all HF categories. Renal impairment was associated with a higher FDE across the entire EF spectrum. CONCLUSION: In this large registry of real-world HF patients, LD use was highest among HFrEF patients. Advanced symptoms, diabetes mellitus and worse renal function were significantly associated with a higher diuretic dose regardless of left ventricular ejection fraction.

ABSTRACT

BACKGROUND: Short-term mechanical circulatory support devices are increasingly used in cardiogenic shock after acute myocardial infarction. As no randomised evidence is available, the choice between high-output Impella or extra-corporeal membrane oxygenation (ECMO) is still a matter of debate. Real-life data are necessary to assess adverse outcomes and to help guide the treatment decision between the different devices. The purpose of this study was to compare characteristics and clinical outcomes of Impella CP/5.0 with ECMO support in patients with cardiogenic shock from myocardial infarction. METHODS: A retrospective, two-centre study was performed on all cardiogenic shock from myocardial infarction patients with Impella CP/5.0 or ECMO support, from 2006 until 2018. The primary outcome was 30-day mortality. Potential baseline imbalance between the groups was adjusted using inverse probability treatment weighting, and survival analysis was performed with an adjusted log-rank test. Secondarily, the occurrence of device-related complications (limb ischaemia, access site-related bleeding, access site-related infection) was evaluated. RESULTS: A total of 128 patients were included (Impella, N=90; ECMO, N=38). The 30-day mortality was similar for both groups (53% vs. 49%, P=0.30), also after adjustment for potential baseline imbalance between the groups (weighted log-rank P=0.16). Patients with Impella support had significantly fewer device-related complications than patients treated with ECMO (respectively, 17% vs. 40%, P<0.01). CONCLUSIONS: Patients treated with Impella CP/5.0 or ECMO for cardiogenic shock after myocardial infarction did not differ in 30-day mortality. More device-related complications occurred with ECMO compared to Impella support.
