Myocardial infarction: measurement of ejection fraction
Indicator
The proportion of patients with acute myocardial infarction with measurement of left ventricular ejection fraction before discharge.
Indicator type
Network / system level indicator.
The indicator would be appropriate to understand and report on the performance of networks or systems of providers.

Rationale
Assessment of left ventricular function by measurement of left ventricular ejection fraction (LVEF) is an important predictor of outcome in patients after a myocardial infarction. It also allows identification of patients who would benefit from specific treatment such as the use of aldosterone antagonists. LVEF should be assessed before discharge in all people who have had ST-segment elevation myocardial infarction (STEMI) or non-ST segment elevation myocardial infarction (NSTEMI).

Specification
Numerator: The number of patients in the denominator who had LVEF measured before discharge.
Denominator: The number of patients with discharged from hospital following an admission with acute myocardial infarction.
Calculation: (Numerator/denominator)*100
Exclusions: Patients who died in hospital.
Data source: Myocardial Ischaemia National Audit Project (MINAP) dataset.
Minimum population: The indicator would be appropriate to understand and report on the performance of networks or systems of providers.
