The effect of risk factors on the global longitudinal strain average was demonstrated by multiple linear regression analysis, and there was statistical significance for the existence of multivessel effects (p = 0.009). Age, sex, hypertension and diabetes mellitus were not predictors for the worsening of global longitudinal strain (Table 5)
