Left ventricular hypertrophy (LVH) is growth in left ventricular mass caused by increased cardiomyocyte size. LVH can be a physiological adaptation to strenuous physical exercise, as in athletes, or it can be a pathological condition, which is either genetic or secondary to LV overload. Physiological LVH is usually benign and regresses upon reduction/cessation of physical activity. Pathological LVH is a compensatory phenomenon, which eventually may become maladaptive and evolve towards progressive LV dysfunction and heart failure (HF). Both interstitial and replacement fibrosis play a major role in the progressive decompensation of the hypertrophied LV. Coronary microvascular dysfunction (CMD) and myocardial ischemia, which have been demonstrated in most forms of pathological LVH, have an important pathogenetic role in the formation of replacement fibrosis and both contribute to the evolution towards LV dysfunction and HF. Noninvasive imaging allows detection of myocardial fibrosis and CMD, thus providing unique information for the stratification of patients with LVH. (Circ J 2016; 80: 555-564).
