Evidence-Based Application of Natriuretic Peptides in the Evaluation of Chronic Heart Failure With Preserved Ejection Fraction in the Ambulatory Outpatient Setting.
Circulation
January 2025
Department of Cardiovascular Medicine, Mayo Clinic, Rochester, MN (Y.N.V.R., A.T., M.M.R., B.A.B.).
Background: Plasma NT-proBNP (N-terminal pro-B-type natriuretic peptide) is commonly used to diagnose heart failure with preserved ejection fraction (HFpEF), but its diagnostic performance in the ambulatory/outpatient setting is unknown because previous studies lacked objective reference standards.
Methods: Among patients with chronic dyspnea, diagnosis of HFpEF or noncardiac dyspnea was determined conclusively by exercise catheterization in a derivation cohort (n=414), multicenter validation cohort 1 (n=560), validation cohort 2 (n=207), and a nonobese Japanese validation cohort 3 (n=77). Optimal NT-proBNP cut points for HFpEF rule out (optimizing sensitivity) and rule in (optimizing specificity) were derived and tested, stratified by obesity and atrial fibrillation.
The effects of high-intensity interval training and moderate-intensity continuous training on patients underwent Coronary Artery Bypass Graft surgery; a systematic review.
Am J Cardiovasc Dis

Cardiac Primary Prevention Research Center, Tehran Heart Center, Tehran University of Medical Sciences Tehran, Iran.
Objectives: To our knowledge, there is no clear consensus on a definitive cardiac rehabilitation method for patients undergoing Coronary Artery Bypass Graft (CABG). We conducted this systematic review to compare and evaluate the effects of two of the most frequent cardiac rehabilitation modalities, high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT), on cardiopulmonary variables.
Methods: We carried out a systematic search of the databases PubMed, Web of Science, Embase, Scopus, and Google Scholar.
Echocardiographic phenotypes of diabetic myocardial disorder: evolution over 15 months follow-up in the ARISE-HF trial.
Cardiovasc Diabetol
January 2025
Cardiology Division, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA.
Background: Diabetic myocardial disorder (DbMD, evidenced by abnormal echocardiography or cardiac biomarkers) is a form of stage B heart failure (SBHF) at high risk for progression to overt HF. SBHF is defined by abnormal LV morphology and function and/or abnormal cardiac biomarker concentrations.
Objective: To compare the evolution of four DbMD groups based on biomarkers alone, systolic and diastolic dysfunction alone, or their combination.
Predicting Heart Rate at the Anaerobic Threshold Using a Machine Learning Model Based on a Large-Scale Population Dataset.
J Clin Med
December 2024
Department of Cardiovascular Medicine, Sakakibara Heart Institute, Tokyo 183-0003, Japan.
For effective exercise prescription for patients with cardiovascular disease, it is important to determine the target heart rate at the level of the anaerobic threshold (AT-HR). The AT-HR is mainly determined by cardiopulmonary exercise testing (CPET). The aim of this study is to develop a machine learning (ML) model to predict the AT-HR solely from non-exercise clinical features.

Eur J Appl Physiol
January 2025
Department of Medicine, University of Udine, P. le Kolbe 4 - 33100, Udine, Italy.
Purpose: The aim of this study was to investigate the influence of prolonged aerobic exercise on cardiac, muscular and renal inflammatory markers in a group of trained obese men.
Methods: Seventeen men (aged 40 ± 6 years; body mass index [BMI] 31.3 ± 2.
