Key result
The first-third ejection fraction at rest is of limited value for detecting patients with coronary artery disease, identifying only 2 of 25 patients with severe CAD.
Why the study?
Does the first-third ejection fraction (1/3 EF) accurately detect patients with coronary artery disease?
Observational (n=47)
Does the first-third ejection fraction (1/3 EF) accurately detect patients with coronary artery disease?
p-value: p=<0.02
The ejection fraction during the first third of systole at rest has limited clinical value for detecting patients with coronary artery disease.
No takes yet. Share an insight, caveat, or question.
1/3 EF at rest should not guide CAD detection; leaves open its adjunctive value in prospective or multimodal protocols.
Kemper et al. (1982) conducted an observational in Coronary artery disease (n=47). First-third ejection fraction (1/3 EF) vs. Normal controls was evaluated on Depressed first-third ejection fraction (1/3 EF) (p=<0.02). The first-third ejection fraction at rest is of limited value for detecting patients with coronary artery disease, identifying only 2 of 25 patients with severe CAD.
