Global and regional left ventricular circumferential strain during incremental cycling and isometric knee extension exercise [PDF]
Echocardiography, 2018 BackgroundThe objective of this study was to investigate left ventricular (LV) circumferential strain responses to incremental cycling and isometric knee extension exercises.MethodsTwenty‐six healthy male participants (age = 30 ± 6 years) were used to study LV global (GCS) and regional circumferential strain at the apex (ACS) and base (BCS) during ...

The association of global longitudinal and global circumferential strain with ejection fraction in patients with aortic stenosis and increased left ventricular mass: a feature tracking CMR study [PDF]
Journal of Cardiovascular Magnetic Resonance, 2015 Background Global longitudinal strain (GLS) and global circumferential strain (GCS) have emerged as important new markers of left ventricular (LV) function. Aortic stenosis (AS) creates pressure overload which produces LV hypertrophy and increased mass.

Global Circumferential Strain by Cardiac Magnetic Resonance Tissue Tracking Associated With Ventricular Arrhythmias in Hypertrophic Cardiomyopathy Patients. [PDF]
Front Cardiovasc Med, 2021 Background: Hypertrophic cardiomyopathy (HCM) is prone to myocardial heterogeneity and fibrosis, which are the substrates of ventricular arrhythmias (VAs). Cardiac magnetic resonance tissue tracking (CMR-TT) can quantitatively reflect global and regional left ventricular strain from different directions. It is uncertain whether the change of myocardial

Comparison between conventional and compressed sensing cine cardiovascular magnetic resonance for feature tracking global circumferential strain assessment. [PDF]
J Cardiovasc Magn Reson, 2021 Feature tracking (FT) has become an established tool for cardiovascular magnetic resonance (CMR)-based strain analysis. Recently, the compressed sensing (CS) technique has been applied to cine CMR, which has drastically reduced its acquisition time. However, the effects of CS imaging on FT strain analysis need to be carefully studied.

The prognostic value of global circumferential strain in patients with suspected myocardial disease. [PDF]
JACC Cardiovasc Imaging, 2015 Measurements of cardiac output by indicator or thermodilution techniques were among the first methods developed to assess cardiac function [(1)][1]. It is clear, however, that even when normalized for body size, cardiac output measured at rest is limited as a clinical measure because the heart ...

Standardized assessment of global longitudinal and circumferential strain - a modality independent software approach [PDF]
Journal of Cardiovascular Magnetic Resonance, 2015 Mean GLS values were -16.2±5.3% and -17.3±5.3% for echocardiography and CMR, respectively. GLS did not differ significantly between the two imaging modalities, which showed strong correlation (r=0.86), a small bias (-1.1%) and narrow 95% limits of agreement (LOA, ±5.4%).
