Functional Mitral Regurgitation Predicts Short-Term Adverse Events in Patients With Acute Heart Failure and Reduced Left Ventricular Ejection Fraction
2017
Functional mitral regurgitation (FMR) is a common finding in patients with acute heart failure (AHF) and reduced left ventricular ejection fraction (heart failure and reduced ejection fraction [HFrEF]). However, its clinical impact remains unclear. We aimed to evaluate the association between the severity of FMR after clinical stabilization and short-term adverse outcomes after a hospitalization for AHF. We prospectively included 938 consecutive patients with HFrEF discharged after a hospitalization for AHF, after excluding those with organic valve disease, congenital heart disease, or aortic valve disease. FMR was assessed semiquantitatively by color Doppler analysis of the regurgitant jet…
Inflammatory pathways in patients with heart failure and preserved ejection fraction.
2008
Immune activation is well established in patients with chronic heart failure and reduced ejection fraction (HF and reduced EF) and is associated with an impaired prognosis. Patients with heart failure and preserved ejection fraction (HF and preserved EF) have an impaired prognosis as well. It is not known whether they have signs of immune activation.We studied patients with HF and preserved EF (n=17, NYHA II [n=7]/III [n=10]) and patients with HF and reduced EF (n=17 NYHA II [n=1]/III [n=16]) and 20 controls. Echocardiography demonstrated preserved ejection fraction (LVEF 59+/-9%), but LV hypertrophy in patients with preserved EF as compared with patients with reduced EF (LVEF 23+/-5%). We …
Role of Rate Control and Regularization Through Pacing in Patients With Chronic Atrial Fibrillation and Preserved Ventricular Function: The VRR Study
2006
Aim: High heart rates in chronic atrial fibrillation (CAF) is one of the factors responsible for hemodynamic alterations and may lead to tachycardiomyopathies. The ventricular rate regulation (VRR) study evaluates the effect of ventricular rate regularization in CAF patients with preserved ventricular function, marked ventricular rate variability, and indications for pacemaker (PM) implantation owing to symptomatic pauses. Rate regularization was achieved using VRR algorithm (INSIGNIA® pacemakers, Guidant Corp., St. Paul, MN, USA). Methods: One month after PM implantation, 58 patients followed two 3-month crossover periods (VRR-OFF; VRR-ON) in which the VRR algorithm was randomized and comp…
Impact of routine invasive strategy on outcomes in patients with non-ST-segment elevation myocardial infarction during 2005–2014: A report from the P…
2020
Background: Non-ST-segment elevation myocardial infarction (NSTEMI) has become the most frequently encountered type of myocardial infarction. The patient clinical profile and management has evolved over the past decade. As there is still a scarcity of data on the latest trends in NSTEMI, changes herein were observed and assessed in the treatment and outcomes in Poland between 2005 and 2014. Methods: A total of 197,192 patients with NSTEMI who enrolled in the Polish Registry of Acute Coronary Syndromes (PL-ACS) between 2005 and 2014 were analyzed. In-hospital and 12-month mortality were assessed. Results: Coronary angiography use increased from 35.8% in 2005–2007 to 90.7% in 2012–2014 (p < 0…
Prognostic value of pulmonary vascular resistance estimated by cardiac magnetic resonance in patients with chronic heart failure.
2014
Pulmonary arterial hypertension is known to be related to worse prognosis in patients with heart failure (HF). Quantification of pulmonary vascular resistance (PVR) still requires invasive right heart catheterization. Recent studies have shown an accurate method for non-invasive estimation of PVR by cardiac magnetic resonance (CMR). Our aim was to evaluate the prognostic value of PVR calculated by CMR in patients with congestive HF.We calculated PVR by CMR in 132 patients [age 65.6 ± 13.1 years, left ventricular ejection fraction (LVEF) 35.1 ± 16.4%, ischaemic aetiology 40%] recently admitted for decompensated HF and derived to our cardiac imaging unit for diagnosis. Patients with cardiac e…
Risk score for early risk prediction by cardiac magnetic resonance after acute myocardial infarction.
2022
BACKGROUND: Cardiac magnetic resonance (CMR) performed early after ST-segment elevation myocardial infarction (STEMI) can improve major adverse cardiac event (MACE) risk prediction. We aimed to create a simple clinical-CMR risk score for early MACE risk stratification in STEMI patients.; METHODS: We performed a multicenter prospective registry of reperfused STEMI patients (n=1118) in whom early (1-week) CMR-derived left ventricular ejection fraction (LVEF), infarct size and microvascular obstruction (MVO) were quantified. MACE was defined as a combined clinical endpoint of cardiovascular (CV) death, non-fatal myocardial infarction (NF-MI) or re-admission for acute decompensated heart failur…
EpCAM and microvascular obstruction in patients with STEMI: a cardiac magnetic resonance study
2020
Abstract Introduction and objectives Microvascular obstruction (MVO) is negatively associated with cardiac structure and worse prognosis after ST-segment elevation myocardial infarction (STEMI). Epithelial cell adhesion molecule (EpCAM), involved in epithelium adhesion, is an understudied area in the MVO setting. We aimed to determine whether EpCAM is associated with the appearance of cardiac magnetic resonance (CMR)-derived MVO and long-term systolic function in reperfused STEMI. Methods We prospectively included 106 patients with a first STEMI treated with percutaneous coronary intervention, quantifying serum levels of EpCAM 24 hours postreperfusion. All patients underwent CMR imaging 1 w…
Left ventricular diastolic and systolic function in normotensive obese subjects: influence of degree and duration of obesity.
1992
The present study was carried out to evaluate systolic and diastolic parameters in overweight and moderately obese, but otherwise healthy subjects, and in a lean control group, to determine whether degree and duration of obesity can influence left ventricular function. A total of 27 subjects, 17 overweight or with moderate obesity and 10 lean, healthy subjects were included. Patients were divided into three groups according to their body mass index (BMI) and to Garrow's criteria as follows: lean control group (BMI less than 25 kg.m-2); overweight subjects (BMI from 25 to 30 kg.m-2); moderately obese subjects (BMI greater than 30 less than 40 kg.m-2). Systolic and diastolic parameters were m…
The prognostic role of CMR using global planimetric criteria in patients with excessive left ventricular trabeculation.
2021
Objectives: Although cardiovascular magnetic resonance (CMR) is widely used in the assessment of left ventricular non-compaction (LVNC), there are no universally accepted diagnostic criteria and limited data regarding their prognostic value. We assessed the long-term prognostic role of the planimetric global Grothoff’s criteria and of the CMR findings in predicting adverse cardiovascular events (CE). Methods: We prospectively enrolled 78 patients (46.7 ± 18.7 years, 33.3% females) with documented positive Jenni’s echocardiographic criteria for LVNC. Cine images were used to quantify function parameters and to assess for the presence of all four quantitative Grothoff’s criteria (global Groth…
CA125 outperforms NT-proBNP in acute heart failure with severe tricuspid regurgitation.
2019
In acute heart failure (AHF) with right ventricular dysfunction, the roles of amino-terminal pro-brain natriuretic peptide (NT-proBNP) and carbohydrate antigen 125 (CA125) are poorly understood, and functional tricuspid regurgitation (TR) severity is thought to indicate a poor prognosis. We examined the prognostic abilities of NT-proBNP and CA125 according to TR status among patients with AHF.TR severity was assessed during index hospitalization (108 ± 24 h after admission) and classified as none/trivial, mild, moderate, or severe. Multivariable Cox regression analysis was performed to assess how pre-discharge CA125 and NT-proBNP were associated with long-term all-cause mortality relative t…
