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.
