Key result
The effect of proximal right coronary artery lesions on right ventricular ejection fraction during exercise was investigated, but results are not reported in the truncated abstract.
Why the study?
Does the location of right coronary artery lesions affect right ventricular ejection fraction during exercise in patients with coronary artery disease?
Observational (n=37)
Does the location of right coronary artery lesions affect right ventricular ejection fraction during exercise in patients with coronary artery disease?
This study evaluates the impact of right coronary artery lesion location on right ventricular ejection fraction during exercise using radionuclide angiography.
Proximal RCA lesions may impair exercise RVEF; hypothesis-generating for RV assessment in CAD.
The effect of the location of right coronary artery (RCA) lesions upon right ventricular ejec- tion fraction (RVEF) during exercise was investigated using first-pass radionuclide angiography. Thirty-seven patients were studied at rest and during upright bicycle exercise: 11 controls (group 1) and 26 patients with significant (>70%) coronary artery stenosis, divided into those without lesions of the RCA proximal to the acute margin (group 2, n = 14) and those with proximal RCA lesions (group 3, n = 12).

Johnson et al. (1979) conducted an observational in Coronary artery disease (n=37). Proximal right coronary artery (RCA) lesions vs. Controls and patients without proximal RCA lesions was evaluated on Right ventricular ejection fraction (RVEF) during exercise. The effect of proximal right coronary artery lesions on right ventricular ejection fraction during exercise was investigated, but results are not reported in the truncated abstract.
