Key result
The abstract describes a study assessing the correlation between systolic time intervals and standard variables of contractility in coronary artery disease, but reports no quantitative results.
Why the study?
Do systolic time intervals correlate with standard variables of contractility and performance obtained at cardiac catheterization in patients with coronary artery disease?
Observational
Do systolic time intervals correlate with standard variables of contractility and performance obtained at cardiac catheterization in patients with coronary artery disease?
This study investigates whether systolic time intervals accurately reflect left ventricular function in coronary artery disease by comparing them to invasive catheterization metrics.
Inconclusive without quantitative results; leaves open correlation of systolic time intervals with catheterization metrics in CAD.
Characteristic changes in systolic time intervals have been described in left ventricular failure, and it has been held that patients with coronary artery disease have similar abnormalities in pre-ejection and ejection times as well as in the length of total electromechanical systole. In order to assess the contribution of systolic time intervals to the clinical evaluation of patients with coronary artery disease, correlative studies were made between systolic time intervals and the standard variables of contractility and performance obtained at cardiac catheterization.

Parker et al. (1974) conducted an observational in Coronary artery disease. Systolic time intervals vs. Standard variables of contractility and performance at cardiac catheterization was evaluated on Correlation between systolic time intervals and standard variables of contractility and performance. The abstract describes a study assessing the correlation between systolic time intervals and standard variables of contractility in coronary artery disease, but reports no quantitative results.
