PATHOLOGY

Detailed explanation-1: -Systole is when the heart muscle contracts. When the heart contracts, it pushes the blood out of the heart and into the large blood vessels of the circulatory system. From here, the blood goes to all of the organs and tissues of the body. During systole, a person’s blood pressure increases.

Detailed explanation-2: -GLS describes the relative length change of the LV myocardium between end diastole and end systole. Mathematically, it can be calculated by the following formula: GLS % = (MLs − MLd)/MLd. MLs is myocardial length at end systole, MLd is myocardial length at end diastole.
