“…This data indicates that LA booster pump dysfunction represents the main correlate of deterioration of the functional capacity. Our finding is in line with a previous study that evaluated LA phasic functions by STE and reported LA booster pump function as the main correlate of functional disability (18). Demonstration of atrial functional failure has a diagnostic utility for distinguishing patients with diastolic HF from those with hypertensive LV hypertrophy (24).…”

“…In accordance with previous studies (3,18), LA volumetric changes and related functions proceeded according to the Frank-Starling mechanism in our HCM population. An inverse relation of the E/E′ ratio with LA phasic functions and the presence of the Frank-Starling mechanism in the LA suggest the existence of a secondary atrial myopathy rather than primary involvement of the atrial tissue in patients with HCM.…”

“…Na forma hipertrófica da doença há um aumento da rigidez atrial, atribuído ao aumento da rigidez e/ou aumento da espessura do miocárdio atrial, responsável pela diminuição da função de reservatório 31,40,65,66 . Nesses pacientes, observou-se que a função atrial esquerda está relacionada à presença e à intensidade dos sintomas de insuficiência cardíaca 66 .…”

“…HCM represents a generalized myopathic process affecting both ventricular and atrial myocardium (14). Most of the patients are in steady condition, although HCM is known as one of the most common cause of sudden death in juvenile patients (13).…”
