Left ventricular global longitudinal strain rate is influenced by stable coronary artery disease

We have read with great interest the article published by Doğduş et al. (1) about the relationship between subclinical left ventricular dysfunction and body mass index. Three-dimensional left ventricular strain echocardiography assessments have shown that overweight and obese patients have worse left ventricular function than normal controls (1). Left ventricular strain imaging is an important tool to assess subclinical left ventricular dysfunction. Stable coronary artery disease (SCAD) is characterized by ischemic symptoms occurring with exercise or emotional or other stressful conditions and symptoms relief with rest (2). Radwan and Hussein (3) have demonstrated that left ventricular global longitudinal strain rate is worse in patients with SCAD than in those without SCAD. Also, left ventricular global longitudinal strain rate is associated with the severity of coronary artery disease (3). “SCORE” is a cardiovascular disease predicting score and is used to predict the patients who have potential risk to have coronary artery disease. Age and sex are the two parameters assessed in SCORE chart (4).
