Prognostic value of left ventricular diastolic function and association with heart rate variability after a first acute myocardial infarction
Why the study?
Does a restrictive left ventricular filling pattern predict cardiac death and heart failure readmission in patients after a first acute myocardial infarction?
Population
64 consecutive patients with first acute myocardial infarction and 31 control subjects
Comparison
Restrictive left ventricular filling… vs Non-restrictive left ventricular filling…
Design
Cohort

Implication
May aid post-MI risk stratification via echocardiography; leaves open whether targeting restrictive filling improves outcomes.
Structured PICO
Does a restrictive left ventricular filling pattern predict cardiac death and heart failure readmission in patients after a first acute myocardial infarction?
P
Population
64 consecutive patients with first acute myocardial infarction and 31 control subjects
I
Intervention
Restrictive left ventricular filling characteristics (deceleration time ≤ 140 ms)
C
Comparator
Non-restrictive left ventricular filling characteristics (deceleration time > 140 ms) and control subjects
O
Outcome
Composite of cardiac death and readmission to hospital with congestive heart failurecomposite
A restrictive left ventricular filling pattern assessed by echocardiography is a strong independent predictor of adverse outcomes after a first acute myocardial infarction.
