Collaboration between dyspnea clinic and primary care physicians to identify heart failure with preserved ejection fraction in the community: Results from the Maebashi City HF project.
J Cardiol
January 2025
Department of Cardiovascular Medicine, Gunma University Graduate School of Medicine, Maebashi, Japan. Electronic address:
Background: Despite increasing awareness in general practice, heart failure with preserved ejection fraction (HFpEF) remains under-diagnosed in the community due to diagnostic difficulties. Dedicated dyspnea clinics are responsible for diagnosing HFpEF and efficient referral from primary care physicians is the key to enhance its role.
Methods: This retrospective analysis was performed to assess the effectiveness of a one-year collaborative project between our dyspnea clinic and the Maebashi Medical Association.
Left ventricular elastance with resting volumetric transthoracic echocardiography identifies different phenotypes in heart failure with preserved ejection fraction: A retrospective analysis of a multicenter prospective observational study.

Cardiology Clinic, University Center Serbia, Medical School, University Clinical Center Serbia, University of Belgrade, Serbia.
Background: Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous entity including patients with different phenotypes of near normal, normal, and supernormal left ventricular (LV) function.
Objectives: To assess the value of resting LV elastance (also known as force) with transthoracic echocardiography (TTE) to identify HFpEF phenotypes.
Methods: In a prospective, observational, multicenter study, 2380 HFpEF patients were recruited from July 2016 to May 2024.
Cathepsin-D and outcomes in peripartum cardiomyopathy: Results from IPAC.
Am Heart J Plus
January 2025
University of Pittsburgh Medical Center, Pittsburgh, PA, United States of America.
Objective: Evaluate the relationship of cathepsin-D (CD) on disease severity and clinical outcomes for women with peripartum cardiomyopathy.
Background: Cathepsin-D is a protease released during oxidative stress that cleaves prolactin (PRL) generating a 16 kDa fragment that is pro-apoptotic, anti-angiogenic, and has been implicated in the pathogenesis of peripartum cardiomyopathy (PPCM).
Methods: In 99 women with newly diagnosed PPCM enrolled in the Investigation in Pregnancy Associated Cardiomyopathy (IPAC) study, CD levels were assessed by ELISA from serum obtained at study entry.

Spinal Muscular Atrophy is an autosomal dominant disease caused by mutations and deletions within the SMN1 gene, with predominantly childhood onset. Although primarily a motor neuron disease, defects in non-neuronal tissues are described in both patients and mouse models. Here, we have undertaken a detailed study of the heart in the Smn2B/- mouse models of SMA, and reveal a thinning of the ventriclar walls as previously described in more severe mouse models of SMA.

Stress echocardiography has evolved from the sole assessment of regional wall motion abnormalities (RWMAs) to the ABCDE protocol, as recommended by the recent clinical consensus statement from the European Association of Cardiovascular Imaging, reflecting the need for a more systematic patient assessment. Steps A, B, C, D, and E assess RWMAs, lung B-lines, left ventricular contractile reserve, coronary flow velocity reserve (CFVR) in mid-distal left anterior descending artery, and heart rate reserve, respectively. Impairment of CFVR is considered as the earliest abnormality in the ischaemic cascade.
