Cardiac troponin (cTn) is instrumental in screening and diagnosing myocardial ischemia in adults. However, the role of cTn screening in the pediatric population is less clear. The purpose of this…
The problem of early recognition of atrial fibrillation (AF) is greatly aggravated by the often silent nature of the rhythm disturbance. In about 1/3 of patients with this arrhythmia, patients…
The purpose of applying a high-pass filter is to attenuate low-frequency noise. This type of noise presents as baseline sway, which may hinder proper assessment of the electrocardiogram. Low-frequency noise…
Cardioselective β blockers are considered to have little impact on lung function at rest in patients with chronic obstructive pulmonary disease (COPD). However, their effects on dynamic hyperinflation, an important…
We read with interest the study by Nozue et al, who investigated clinical and lesion-related factors associated with coronary plaque progression versus regression in statin-treated patients. The investigators reported that…
The incremental value of left atrial (LA) deformation analysis by speckle tracking echocardiography compared with LA volume or LA ejection fraction as a cardiovascular risk marker has not been evaluated…
Biventricular device implantation with the insertion of a transvenous left ventricular (LV) lead can be challenging. The aim of this study was to identify predictors of procedural difficulty measured by…
Chronic kidney disease is associated with an increased left ventricular (LV) mass. Few data are available regarding the effect of renal transplantation on LV mass regression or the clinical factors…
Obesity is related to left ventricular hypertrophy (LVH). Whether LVH on electrocardiography (ECG-LVH) is a result of increased cardiac electrical activity or due to increased left ventricular mass (LVM) remains…
There are well-documented changes in thyroid hormone metabolism that accompany heart failure (HF). However, the frequency of thyroid hormone abnormalities in HF with preserved ejection fraction (HFpEF) is unknown, and…
