Detection of Left Ventricular Systolic Dysfunction in Cardiac Amyloidosis with Strain Rate Echocardiography .
2006
Background We examined the potential role of Doppler myocardial imaging including tissue velocity imaging, strain imaging, and strain rate imaging for detection of left ventricular systolic dysfunction in cardiac amyloidosis (CA) and determined the minimum dataset required to make the diagnosis. Methods and Results Doppler myocardial imaging was performed in 103 patients with amyloidosis (AL). Peak longitudinal systolic tissue velocity, systolic strain rate (sSR), and systolic strain (sS) were determined for 16 left ventricular segments. Radial and circumferential sSR and sS were also measured. Patients with increased left ventricular wall thickness were classified with advanced-CA, and the…
Differential prognostic effect of systolic blood pressure on mortality according to left-ventricular function in patients with acute heart failure.
2009
Aims To evaluate the relationship between systolic blood pressure (SBP) and long-term mortality in patients with acute heart failure (AHF) stratified by ejection fraction (LVEF): reduced (≤40%) vs. preserved (≥50%). Methods and results We studied 1049 consecutive patients admitted with AHF. Systolic blood pressure was determined in the emergency department. Left-ventricular ejection fraction was categorized as ≤40% (n = 288), 41–49% (n = 174), or ≥50% (n = 587). Cox regression analysis was used for multivariable analysis. Mean age and SBP were 73 ± 11 years and 150 ± 36 mmHg, respectively. During a median follow-up of 18 months, 290 deaths (33.1%) were identified. Higher SBP was associated …
Tricuspid Regurgitation and Mortality Risk Across Left Ventricular Systolic Function in Acute Heart Failure.
2015
BACKGROUND Tricuspid regurgitation (TR) is a common echocardiographic finding that has been related to adverse outcome under various clinical scenarios. Nevertheless, evidence supporting its prognostic value in heart failure (HF) is scarce, and, in most cases, contradictory. We evaluated the association of TR grade with 1-year all-cause mortality in acute HF (AHF). METHODS AND RESULTS: We included 1,842 consecutive patients admitted for AHF. Mean age was 72.8±11.3 years, 51% were female and 45.5% had LVEF <50%. The severity of TR was graded in non-TR, mild (1), moderate (2), moderate-severe (3) and severe (4). At 1-year follow-up, 370 patients (20.1%) had died. In patients with LVEF ≥50%, a…
Length of stay and risk of very early readmission in acute heart failure
2016
In patients admitted for acute heart failure (AHF), optimal length of stay (LOS) remains controversial. Longer hospitalizations are associated with worse prognosis, but little is known about short hospitalizations. The aim of this work was to evaluate the relationship between LOS and the risk of short-term readmission in patients discharged after a hospitalization for AHF.We included 2110 consecutive patients. The independent associations between LOS and unplanned 10, 15 and 30-day readmissions were evaluated by Cox regression analysis adjusted for competing events. LOS was categorized as LOS1: ≤4days, LOS2: 5-7days, LOS3: 8-10days, and LOS4:10days.The mean age was 73±11years and 52.6% exhi…
Differences in blood pressure control and stroke mortality across Spain: the Prevención de Riesgo de Ictus (PREV-ICTUS) study.
2007
The objective was to assess the stroke risk and prevalence of the cardiovascular risk factors and to analyze their relationship with the specific stroke rates of mortality in each of the autonomic communities of Spain. We conducted a multicenter, cross-sectional study of population >60 years old in Spanish primary care centers. In all of the subjects, clinical, biochemical, and electrocardiographic data were obtained, and the 10-year stroke risk was calculated using the Framingham score. Mortality rates of stroke, age and sex adjusted, were obtained for each of the autonomic communities from the Ministry of Health. A total of 7343 subjects (mean age: 71.6 years, 53.4% women, 34.4% obese…
Prognostic Value of Strain by Tissue Tracking Cardiac Magnetic Resonance After ST-Segment Elevation Myocardial Infarction
2018
The aim of this study was to evaluate the prognostic value of strain as assessed by tissue tracking (TT) cardiac magnetic resonance (CMR) soon after ST-segment elevation myocardial infarction (STEMI).The prognostic value of myocardial strain as assessed post-STEMI by TT-CMR is unknown.The authors studied the prognostic value of TT-CMR in 323 patients who underwent CMR 1 week post-STEMI. Global (average of peak segmental values [%]) and segmental (number of altered segments) longitudinal (LS), circumferential, and radial strain were assessed using TT-CMR. Global and segmental strain cutoff values were derived from 32 control patients. CMR-derived left ventricular ejection fraction, microvasc…
Abnormal Myocardial Perfusion After Infarction in Patients With Persistent TIMI Grade-3 Flow. Only an Acute Phenomenon?
2007
Introduction and objectives It has been suggested that abnormal perfusion as derived from cardiovascular magnetic resonance imaging (CMR) is a transient dysfunction of microcirculation after myocardial infarction (MI) with TIMI 3 flow. We hypothesized that defects of myocardial perfusion may persist during the following months. Methods Forty-seven patients with MI and sustained TIMI 3 flow underwent intracoronary myocardial contrast echocardiography (MCE) 1 week and 6 months after infarction. Abnormal perfusion by MCE was regarded as >1 hypoperfused segment. Results At one week, 20 patients showed abnormal perfusion as derived from MCE. At six months 10 patients displayed chronic abnormal p…
Effects of inspiratory muscle training in patients with heart failure with preserved ejection fraction
2013
Heart failure with preserved ejection fraction (HFpEF) is remarkably common in elderly people with highly prevalent comorbid conditions. Despite its increasing in prevalence, there is no evidence-based effective therapy for HFpEF. We sought to evaluate whether inspiratory muscle training (IMT) improves exercise capacity, as well as left ventricular diastolic function, biomarker profile and quality of life (QoL) in patients with advanced HFpEF and nonreduced maximal inspiratory pressure (MIP).A total of 26 patients with HFpEF (median (interquartile range) age, peak exercise oxygen uptake (peak VO2) and left ventricular ejection fraction of 73 years (66-76), 10 ml/min/kg (7.6-10.5) and 72% (6…
Comparison of Ivabradine Versus Metoprolol in Early Phases of Reperfused Anterior Myocardial Infarction With Impaired Left Ventricular Function: Prel…
2009
BACKGROUND: beta-blockers in ST-segment elevation myocardial infarction (STEMI) are indicated for patients without a contraindication, particularly in patients with high heart rates (HR) or blood pressures. Epidemiological studies have shown that elevated HR represents a risk factor for cardiovascular morbidity. The study investigates the feasibility, tolerability, and the effects after 30 days of follow-up of ivabradine (IVA) versus metoprolol (METO) in early phases of anterior STEMI reperfused by percutaneous coronary intervention (PCI). METHODS AND RESULTS: Patients with a first anterior STEMI, Killip class I-II, an acceptable echocardiographic window, and admitted within 4hours of the o…
Sex-Specific Ventricular Arrhythmias and Mortality in Cardiac Resynchronization Therapy Recipients
2021
OBJECTIVES The study goal was to examine whether there are sex-related differences in the incidence of ventricular arrhythmias and mortality in CRT-defibrillator (CRT-D) recipients. BACKGROUND Few studies have evaluated sex-related benefits of cardiac resynchronization therapy (CRT). Moreover, data on sex-related differences in the occurrence of ventricular tachyarrhythmias in this population are limited. METHODS A multicenter retrospective study was conducted in 460 patients (355 male subjects and 105 female subjects) from the UMBRELLA (Incidence of Arrhythmia in Spanish Population With a Medtronic Implantable Cardiac Defibrillator Implant) national registry. Patients were followed up thro…
