Right heart dysfunction and readmission risk across left ventricular ejection fraction status in patients with acute heart failure
2021
Abstract Background Right heart dysfunction (RHD) parameters, such as right ventricular to pulmonary artery uncoupling or significant tricuspid regurgitation (TR) are increasingly important in heart failure (HF), especially in patients with preserved ejection fraction. In this study, we aimed to evaluate the association of advanced RHD with the risk of recurrent admissions across the spectrum of left ventricular ejection fraction (LVEF). Methods We included 3,383 consecutive patients discharged for acute HF (AHF). Of them, in 1,435 (42.4%) pulmonary artery systolic pressure (PASP) could not be accurately measured, leaving a final sample size of 1,948 patients. Advanced RHD was defined as th…
Sex-related differences in mortality following an admission for acute heart failure across left ventricular ejection fraction spectrum
2021
Abstract Background Prognosis in heart failure (HF) may differ between women and men. However, data is conflicting and sex-related differences in prognosis may be determined by left ventricular ejection fraction (LVEF) status. We sought to evaluate the prognostic differences between women and men with HF following an admission for acute HF (AHF). Methods We included 4,812 patients consecutively admitted for AHF in a multicenter registry from 3 hospitals in Valencia (Spain). Study endpoints were all-cause, cardiovascular (CV), and HF-related mortality at 6-months follow-up. Multivariable Cox regression models were fitted to investigate sex-related differences across LVEF status. Results 2,24…
0470 : Serum IF1 concentration as a predictor of mortality in coronary heart disease patients
2015
Aim The ecto-F1-ATPase/P2Y13 pathway plays a key role in reverse cholesterol transport. Exogenous IF1, known as the natural mitochondrial specific inhibitor of F1-ATPase activity, inhibits ecto-F1-ATPase activity and decreases HDL-C uptake by hepatocytes. We previously found that IF1 is present in human serum and is negatively associated with coronary heart disease (CHD). Here, we investigated the relationship between serum IF1 concentration and mortality in CHD patients. Methods Serum IF1 was measured in 624 CHD patients aged 45-74 from the GENES (Genetique et ENvironement en Europe du Sud) study. After 9.1 years follow up, mortality rate was 24.5%. Results Patients who had died were older…
Secondary adherence to beta-blockers after ST-elevation myocardial infarction without ventricular dysfunction.
2020
Introduction and objectives: Adequate medication intake affects treatment effectiveness. The aim of this study was to establish the impact of prescription and secondary adherence to beta-blockers on medium-and long-term and long-term cardiovascular outcomes, after a first type 1 ST-elevation myocardial infarction (STEMI) episode without heart failure or left ventricular ejection fraction >= 40%. Methods: A retrospective observational study was conducted in a cohort of patients admitted from 2008 to 2013 to the University Clinical Hospital in Valencia. Competing risk analysis assessed the relationship between cardiovascular mortality or new vascular event with beta-blocker prescription and s…
Long-Term Use of Deferiprone Enhances Significantly the Left Ventricular Ejection Function in Thalassemia Major
2011
Abstract Abstract 5302 Background: A multicentre randomized controlled trial (RCT) was designed to assess the effectiveness of long-term sequential deferiprone-deferoxamine (DFO-DFP) versus DFP alone to treat thalassaemia major (TM) (Maggio et al.,2009). Effectviness, survival, adverse events and costs were comparable between the groups. These findings were confirmed in a further 21-month follow-up (Pantalone et al., 2011). Moreover, deferiprone-alone has been reported to be superior to deferoxamine for the removal of cardiac iron and improvement in left ventricular ejection function (LVEF). However, little is known of its relative effect on LVEF after long-term treatment. Therefore, data f…
Left ventricular non-compaction cardiomyopathy in children: Is segmental fibrosis the cause of tissue Doppler alterations and of EF reduction?
2009
Noncompaction of the ventricular myocardium (LVNC) is a rare congenital cardiomyopathy resulting from an arrest in normal endomyocardial embryogenesis. In 2002 Jenni et al. [Jenni R, Wyss CA, Oechslin EN, Kaufmann PA. Isolated ventricular noncompaction is associated with coronary microcirculatory dysfunction. J Am Coll Cardiol 2002; 39:450-454.] reported a microvascular dysfunction in 12 patients affected by non compaction: areas of restricted myocardial perfusion have been documented by scintigraphy, suggesting a reduction of Coronary flow reserve. McMahon et al reported in a recent article a reduction of TD velocities in children with noncompaction of the left ventricle, compared with nor…
Left ventricular ejection fraction recovery in patients with heart failure treated with intravenous iron: a pilot study
2016
Aims In patients with heart failure with reduced ejection fraction (HFrEF) and iron deficiency, treatment with intravenous iron has shown a clinical improvement regardless of anaemic status. Cardiac magnetic resonance (CMR) T2* sequence has shown a potential utility for evaluating myocardial iron deficiency. We aimed to evaluate whether T2* sequence significantly changes after ferric carboximaltose (FCM) administration, and if such changes correlate with changes in left ventricle ejection fraction (LVEF). Methods and results In this pilot study, we included eight patients with chronic symptomatic (New York Heart Association II–III) HFrEF and iron deficiency. A CMR, including T2* analysis, w…

Glycolysis Metabolites and Risk of Atrial Fibrillation and Heart Failure in the PREDIMED Trial
2021
The increased prevalence of atrial fibrillation (AF) and heart failure (HF) highlights the need to better understand the mechanisms underlying these cardiovascular diseases (CVDs). In the present study, we aimed to evaluate the association between glycolysis-related metabolites and the risk of AF and HF in a Mediterranean population at high risk of CVD. We used two case-control studies nested within the PREDIMED trial. A total of 512 incident AF cases matched to 734 controls, and 334 incident HF cases matched to 508 controls, were included. Plasma metabolites were quantified by using hydrophilic interaction liquid chromatography coupled with high-resolution negative ion mode MS detection. C…
Chronic Kidney Disease, Diabetes, and Risk of Mortality After Acute Myocardial Infarction: Insight From the FAST-MI Program
2020
Diabetes is associated with a substantially increased risk of all-cause death, mainly driven by cardiovascular (CV) mortality. Furthermore, diabetes is associated with poorer outcomes after acute myocardial infarction (AMI) (1). Impaired glomerular filtration rate (GFR) is also associated with an increased risk of CV mortality (2). However, whether diabetes still confers a higher risk of mortality in patients with impaired GFR remains unknown. The aim of this study was to assess the long-term prognostic significance of both diabetes and renal impairment in two prospective nationwide cohorts of AMI patients: FAST-MI (French Registry of Acute ST-Elevation or non-ST-elevation Myocardial Infarc…
