ABSTRACT
Background: Left ventricular outflow tract obstruction (LVOTO) impairs survival and diminishes quality of life in patients with hypertrophic obstructive cardiomyopathy (HOCM). In this study, we aimed to investigate the safety and the efficacy of earlier alcohol septal ablation (ASA) in patients with HOCM. Methods: A total of 47 patients with mildly symptomatic HOCM (NYHA II) and having poor functional capacity despite maximal tolerated medical therapy were included. Results: The mean age of the patients was 55 ± 14, and 57% of the patients were male. All clinical endpoint targets including 30 d mortality (1% vs. 0% p < 0.01), 30 d adverse complications (10% vs. 0% p < 0.01), 30 d complete heart block resulting in need for permanent pacemaker (10% vs. 4.2% p < 0.01), more than moderate residual mitral regurgitation (5% vs. 2.1% p < 0.01), repeat procedure rate (10% vs. 4.2% p < 0.01), improvement of (NYHA) class (90% vs. 95.7% p < 0.01), rest and provoked (LVOT) gradient < 50 mmHg (90% vs. 97.8% p < 0.01) were significantly reached. Conclusions: In patients with mildly symptomatic HOCM (NYHA II), earlier ASA may be performed as an effective and safe procedure in experienced centers.
ABSTRACT
Background: The Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) is a scoring system that is easy to use in outpatient clinics or at the bedside, and was developed to predict the survival of heart failure patients after hospitalization. Objectives: This study aims to evaluate the relationship between the MAGGIC score and cardiorenal syndrome (CRS) in patients with acute decompensated heart failure with reduced ejection fraction (HFrEF). Methods: This retrospective, single-center study, included 706 patients with New York Heart Association II-IV who were hospitalized and discharged for acute decompensated heart failure between 2016 and 2021. CRS type 1 was defined as acute worsening of cardiac function leading to renal dysfunction. Patients were divided into two groups: those with CRS and those without. The MAGGIC score of all patients was determined. The primary outcome was the occurrence of CRS. Results: CRS developed in 132 patients. The MAGGIC score was higher in CRS (+) patients compared to CRS (-) patients (30.70 ± 8.09 vs. 23.96 ± 5.59, p < 0.001). After a multivariable analysis, MAGGIC score [odds ratio (OR): 3.92, p < 0.001], sodium (OR: 0.92, p = 0.003), N terminal pro B type natriuretic peptide (OR: 1.78, p = 0.009), hs troponin (OR: 1.28, p = 0.044), MRA (OR: 0.61, p = 0.019) and furosemide dose (OR: 1.03, p = 0.001) were found to be independent predictors of CRS development. The MAGGIC score was associated with CRS development (area under curve = 0.778). Conclusions: The MAGGIC score may be associated with CRS in HFrEF patients.
