BACKGROUND Patients eligible for cardiac resynchronisation therapy (CRT) have an indication for primary prophylactic implantable cardioverter defibrillator (ICD) therapy. However, response to CRT might influence processes involved in arrhythmogenesis and therefore change the necessity of ICD therapy in certain patients. METHOD In 202 CRT-defibrillator patients, the association between baselin...

AIMS To investigate the combination of heart rate turbulence (HRT) and deceleration capacity (DC) as risk predictors in post-infarction patients with left ventricular ejection fraction (LVEF) > 30%. METHODS AND RESULTS We enrolled 2343 consecutive survivors of acute myocardial infarction (MI) (<76 years) in sinus rhythm. HRT and DC were obtained from 24 h Holter recordings. Patients with both...

BACKGROUND Patients with chronic kidney disease (CKD) are associated with increased cardiovascular morbidity and mortality. An increase in the ratio of pre-ejection period (PEP) to ejection time (ET) is correlated with an increase in left ventricular mass index (LVMI) and a decrease in left ventricular ejection fraction (LVEF). Brachial PEP (bPEP) and brachial ET (bET) can be automatically dete...

Patients who have experienced a myocardial infarction (MI) are at increased risk of sudden cardiac death (SCD). With the advent of implantable cardioverter-defibrillators (ICDs), accurate risk stratification has become very relevant. Numerous investigations have proven that a reduced left ventricular ejection fraction (LVEF) significantly increases the SCD risk. Furthermore, ICD implantation in...

Utilizing a dynamic radionuclide method, the right and left ventricular ejection fractions were measured in 96 men with arteriographically defined coronary arterial disease and in 14 normal subjects. The radionuclidically estimated right ventricular ejection fraction (RVEF) correlated with the RVEF measured with biplane cineventriculographic studies (r = 0.80; n = 43), and the left ventricular ...

Left ventricular (LV) function is an important predictor of morbidity and mortality after myocardial infarction (MI). Changes in LV function have been examined during the early and late phases after MI, but serial measurements of LV function during the subacute period have not been performed. To assess sequential changes in LV function during the subacute period after MI, we used quantitative t...

T he European Society of Cardiology (ESC) recently published new guidelines for the diagnosis and treatment of acute and chronic heart failure (HF). 1 The new nomenclature includes separating patients with HF into 3 distinct groups depending on the left ventricular ejection fraction (LVEF): preserved LVEF (≥50%), mid-range LVEF (40–49%), and reduced LVEF (≤40%). Although there have been several...

To assess left ventricular ejection fraction (LVEF) accurately, cardiac magnetic resonance (CMR) can be indicated and lays on the evaluation of multiple slices of the left ventricle in short axis (CMRSAX). The objective of this study was to assess another method consisting of the evaluation of 2 long-axis slices (CMRLAX) for LVEF determination in acute myocardial infarction.One hundred patients...

There are limited data regarding factors affecting outcomes among acute coronary syndrome (ACS) patients presenting with varying degrees of left ventricle (LV) dysfunction. We aimed to identify factors associated with mortality according to LV ejection fraction (LVEF) at 1st admission in ACS patients.A total of 8983 ACS patients prospectively enrolled in the Acute Coronary Syndrome Israeli Surv...

OBJECTIVE To observe the effect and safety of cardiac rehabilitation (CR) exercise in ischemic cardiomyopathy and to compare the results between patients with preserved left ventricular ejection fraction (LVEF) and reduced LVEF. METHODS Patients with ischemic cardiomyopathy with LVEF <50% were included as subjects. The patients were classified into the preserved LVEF (pLVEF; LVEF 41%-49%) gro...
