.
Conclusion: Isolated DiaD is associated with altered breathing pattern and gas exchange similar to systolic dysfunction. Elevated left atrial volume, higher
early mitral inflow velocity to early mitral annular velocity ratio, or both are predictive of exercise capacity and elevated ventilatory responses in patients
with DiaD suggesting a role for dysfunctional ventricular relaxation.

Estudo comprova o comprometimento da performance para o exercício em pacientes com disfunção diastólica isolada.
.
Queixa frequente desse tipo de paciente, agora comprovada como verdadeira.
.
Quem aparece como sempre, é o volume atrial esquerdo. Sendo preditivo da capacidade física!
