Background: Speckle tracking echocardiography (STE) may be useful in early detection of contractile dysfunction in severe aortic stenosis (AS) patients. Aims and Objectives: The present study aims to evaluate the global longitudinal strain (GLS), global circumferential strain (GCS), and strain rates in patients with severe AS and the role of STE in predicting the development of symptoms or left ventricular (LV) dysfunction in them. Methods and Results: This was a single-centered, prospective, observational study, done at a tertiary care hospital in north India. The study recruited 30 patients with severe AS and 10 healthy controls. Patients underwent two-dimensional echocardiography and STE at baseline and 6 months. Baseline characteristics were similar between the cases and controls. Majority of severe AS patients were symptomatic (n = 24; 80%). LV ejection fraction (LVEF) was similar between cases and controls at baseline and 6 months. Cases had a significantly worse GLS (−-19.3 ± 5.66 vs. -30.4 ± 3.63), GCS (−-29.6 ± 8.48 vs. −-33.6 ± 2.55), and strain rate parameters than the controls at baseline and had a significant decline in these parameters at 6 months. Among 6 asymptomatic patients, 3 developed symptoms and these patients had a significantly greater decline in GLS at 6 months as compared to asymptomatic patients. Conclusions: The present study revealed that patients with severe AS had an abnormal GLS and GCS to begin with, which was not picked by LVEF. Further, there was a significant worsening of these STE parameters at 6 months and those who had a greater decline were more likely to develop new symptoms.
