Simple Electrocardiographic Score Can Predict Left Ventricular Reverse Remodeling in Patients With Non-Ischemic Cardiomyopathy.

Left ventricular reverse remodeling (LVRR) is a favorable response in non-ischemic, non-valvular cardiomyopathy (NICM) patients. Recently, 18-lead body surface electrocardiography (ECG), the standard 12-lead ECG with synthesized right-sided/posterior chest leads, has been developed, but its predictive value for LVRR has not been evaluated. Of 216 consecutive hospitalized NICM patients with LV ejection fraction (LVEF) ≤35%, we studied 125 who received optimization of their heart failure treatment and had 18-lead ECG and echocardiography data available for evaluating LVRR, defined as an absolute increase in LVEF ≥10% concomitant with LVEF ≥35% after 1-year optimized treatment.

Old-Age Onset Progressive Cardiac Contractile Dysfunction in a Patient with Polycystic Kidney Disease Harboring a PKD1 Frameshift Mutation.

A 70-year-old man with dyspnea was admitted to our department and received standard therapy for recurrent heart failure. He was diagnosed with polycystic kidney disease (PKD) in his thirties and received hemodialysis for 4 years before undergoing renal transplantation at age 45. Although his left ventricular ejection fraction (LVEF) was preserved in his 50s, LVEF decreased progressively from 61% to 24%, while left ventricular diastolic dimension (LVDd) increased from 54 mm to 65 mm between 63 and 69 years of age.

A Development of Nucleic Chromatin Measurements as a New Prognostic Marker for Severe Chronic Heart Failure.

Background: Accurate prediction of both mortality and morbidity is of significant importance, but it is challenging in patients with severe heart failure. It is especially difficult to detect the optimal time for implanting mechanical circulatory support devices in such patients. We aimed to analyze the morphometric ultrastructure of nuclear chromatin in cardiomyocytes by developing an original clinical histopathological method.

Usefulness of transient elastography for noninvasive and reliable estimation of right-sided filling pressure in heart failure.

Accurate noninvasive assessment of right atrial pressure (RAP) is important for volume management in patients with heart failure (HF). Transient elastography is a noninvasive and reliable method to assess liver stiffness (LS). We investigated the value of LS for evaluation of RAP in patients with HF without structural liver disease.

Switching from carvedilol to bisoprolol ameliorates adverse effects in heart failure patients with dizziness or hypotension.

Background: Treatment with carvedilol is an established primary therapy for patients with heart failure (HF). However, its most common adverse effects, dizziness and hypotension, often discourage continuation or dosage increase. The aim of this study was to examine whether switching to bisoprolol from carvedilol would help to avoid adverse symptoms and signs related to carvedilol administration.
