Q. Assessment of Diastdlic Function?

Myocardial ischemia Clters diastolic function of left ventricle. The earliest abnormality to appear with prolonged ischemia is delayed myocardial relaxation i.e. A > E., increased deceleration time. Diastolic function after myocardial infarction (MI) depends upon the interaction of various factors:

  •  Ventricular compliance
  •  LA pressure
  •  Loading conditioos
  •  Heart rate
  • a ' Medications

Patients with severe LV dysfunction after MI demonstrate restrictive filling pattern i.e. E >>> A and decreased deceleration time. Patients with restrictive transmitral filling pattlern most likely experience heart failure.
