HF condition, it leads to raised blood pressure, heart muscle cell and fibroblasts hypertrophy, as well as collagen accumulation on interstitial tissues.4 This scenario leads to extracellular matrix protein synthesis,5 remodeling and replace of functional to scarring tissue within the heart. Furthermore, the increased vasoconstriction causes

• The hypertrophy can range from focal segmental hypertrophy to diffuse global hypertrophy. • In approximately 10% of patients the hypertrophy is limited to 1– 2 segments. • As the hypertrophy is often noncontiguous, all LV segments should be carefully examined from base to apex in all available views.

hypertrophy exclusively refers to an increase in the volume of cardiac muscle cells. Although clinically distinct, hypertrophy and HF have many molecular features in common. In addition, hypertrophy of cardiac myocytes and fibrosis are almost universal prerequisites for HF [3,11,15]. Therefore, research into the molecular

Left ventricular hypertrophy (LVH) is usually considered to be a compen satory adjustment of heart muscle to an inreased work load. LVH develops in the course of valvular or congenital heart disease, or when part of the myocardium is damaged by long-standing ischemia or infarction. In the

Left ventricular (LV) hypertrophy may reflect physiological adaptation to an increased work load of the heart following intense physical training. However, LV hypertrophy often represents a pathophysiologic condition, and can develop due to intrinsic stimuli (cardiomyopathy), or secondary to extrinsic stimuli, such as pressure or volume overload
