Validity and reliability of the 6-min stepper test in hypertensive individuals.
J Hypertens
March 2025
Hacettepe University, Faculty of Physical Therapy and Rehabilitation, Department of Cardiorespiratory Physiotherapy and Rehabilitation, Ankara, Turkey.
Background: Hypertension is a common public health problem characterized by high blood pressure (BP) and associated with complications such as coronary artery disease, stroke, and renal failure. Physical activity and exercise regulate BP, and assessment of exercise capacity is a cornerstone of exercise training.
Objective: The aims of this study were to evaluate the validity and reliability of the 6-min stepper test (6MST) in hypertensive individuals and compare their physiological responses during the 6MST and 6-min walk test (6MWT).
Coronary Artery Calcium Detection with Dual-Energy Posteroanterior and Lateral Chest Radiography: Imaging Clues and Added Value of the Lateral View.
Radiol Cardiothorac Imaging
April 2025
Department of Radiology, Naval Medical Center San Diego, 34800 Bob Wilson Dr, San Diego, CA 92134-5000.
Purpose To evaluate the accuracy of detection based on level of interpreter experience when reporting coronary artery calcium (CAC) on dual-energy (DE) posteroanterior (PA) and lateral chest radiographs and demonstrate the accuracy of specific imaging clues. Materials and Methods Retrospective review of 45-70-year-old patients who underwent DE PA and lateral chest radiography between March 1, 2021, and June 30, 2021, and also underwent noncontrast chest CT scan within 3 years. Following instruction of DE principles and the appearance of CAC, seven readers interpreted the DE chest radiographs to state if CAC was possibly present, definitely present, or not present; estimate ordinal CAC score; and report imaging clues present.

Catheter Cardiovasc Interv
March 2025
Division of Cardiovascular Medicine, Tsuchiura Kyodo General Hospital, Ibaraki, Japan.
Background: Limited research has explored the prognostic significance of changes in coronary flow velocity reserve (CFVR), as measured by stress-transthoracic Doppler echocardiography (S-TDE), following elective percutaneous coronary intervention (PCI). This study aimed to assess whether post-PCI changes in CFVR are associated with major adverse cardiac events (MACE) and to identify baseline clinical factors that predict improvement of CFVR.
Methods: A retrospective analysis was performed on 184 patients who underwent elective FFR-guided PCI for the left anterior descending (LAD) artery.
Assessing the diagnostic utility of cardiopulmonary exercise testing in evaluating coronary artery disease.
J Int Med Res
March 2025
Department of Cardiology, Chengdu Second People's Hospital, Chengdu, Sichuan, China.
ObjectiveThis retrospective study aimed to investigate the correlation between the cardiopulmonary exercise test (CPET) and the severity of coronary stenosis (SYNTAX score) in patients with stable coronary artery disease (SCAD), thereby assessing CPET's diagnostic value.MethodsWe classified 220 patients who underwent coronary angiography into coronary heart disease (CHD) and non-CHD groups based on stenosis severity. Patients with SCAD were categorized into mild, moderate, and severe groups by the SYNTAX score.

J Int Med Res
March 2025
Division of Cardiology, Qinghai University Affiliated Hospital, Xining, China.
This article outlines a comprehensive analysis of the progress in the study of Wellens syndrome, which starts from a large body of relevant literature and systematically elaborates on the in-depth discussion, including the definition of the Wellens syndrome and the relationship between myocardial ischemia and coronary artery lesions. In terms of clinical manifestations, the characteristic electrocardiographic changes and related symptoms are described in detail. In terms of diagnostic methods, it ranges from the identification of electrocardiographic features to the combined use of myocardial marker testing and imaging.
