Left ventricular hypertrophy and myocardial work in amateur marathon runners.

ABSTRACT:

Aims

To investigate the left ventricular hypertrophy (LVH) and myocardial work, and their association in amateur marathon runners.

Methods

Amateur marathon runners were categorized into LVH and non-LVH groups according to international guidelines and further classified by gender. Healthy individuals without established exercise habits served as the control group. The global work index (GWI), global constructive work (GCW), global work efficiency (GWE), and global wasted work (GWW) were calculated using the pressure-strain loop methodology. The Firth logistic regression model was used to analyze the factors influencing LVH. Spearman correlation analysis was utilized to examine the relationship between running characteristics and myocardial work parameters.
