Assessment of cardiac function using the modified ejection fraction as an indicator of myocardial circumferential strain

open access: yesJournal of Biomechanical Science and Engineering, 2022
Although cardiac strain has been used as a practical mechanical indicator to estimate cardiac functions, measurement of strain is still difficult due to the need for operator proficiency and special equipment to perform echocardiography and magnetic ...

Left ventricular functional recovery of infarcted and remote myocardium after ST-segment elevation myocardial infarction (METOCARD-CNIC randomized clinical trial substudy)

open access: yesJournal of Cardiovascular Magnetic Resonance, 2020
Background We aimed to evaluate the effect of early intravenous metoprolol treatment, microvascular obstruction (MVO), intramyocardial hemorrhage (IMH) and adverse left ventricular (LV) remodeling on the evolution of infarct and remote zone ...

Impaired Elastic Properties of the Ascending Aorta in Fetuses With Coarctation of the Aorta

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Abnormal aortic elastic properties are major notable vasculopathy involved in coarctation of the aorta (CoA). However, there are no reports on aortic wall elastic characteristics in fetuses with CoA.

Global circumferential and radial strain among patients with immune checkpoint inhibitor myocarditis

open access: yesJACC Cardiovascular Imaging, 2022
Background: GCS and GRS are reduced with cytotoxic chemotherapy. There are limited data on the effect of ICI myocarditis on GCS and GRS. Objectives: To detail the role of global circumferential (GCS) and radial strain (GRS) in immune checkpoint inhibitor

Ventricular strain analysis in patients with no structural heart disease using a vendor-independent speckle-tracking software

open access: yesBMC Cardiovascular Disorders, 2020
Background Ventricular strain measurements vary depending on cardiac chamber (left ventricle [LV] or right ventricle [RV]), type of strain (longitudinal, circumferential, or radial), ventricular level (basal, mid, or apical), myocardial layer ...

Cardiac magnetic resonance feature tracking global and segmental strain in acute and chronic ST-elevation myocardial infarction

open access: yesScientific Reports, 2022
Strain is an important imaging parameter to determine myocardial deformation. This study sought to 1) assess changes in left ventricular strain and ejection fraction (LVEF) from acute to chronic ST-elevation myocardial infarction (STEMI) and 2) analyze ...

Left ventricular circumferential strain and coronary microvascular dysfunction: A report from the Women’s Ischemia Syndrome Evaluation Coronary Vascular Dysfunction (WISE-CVD) Project

open access: yesInternational Journal of Cardiology, 2020
Aims: Women with ischemia but no obstructive coronary artery disease (INOCA) often have coronary microvascular dysfunction (CMD). Left ventricular (LV) circumferential strain (CS) is often lower in INOCA compared to healthy controls; however, it remains ...
