Diagnostic coronary arteriography causes a temporary depression of left ventricular function, which is compensated by the Frank-Starling mechanism to maintain adequate cardiac output.

Does diagnostic coronary arteriography alter cardiac performance in patients with heart disease?
Diagnostic coronary arteriography causes a temporary depression of left ventricular function, which is compensated by the Frank-Starling mechanism to maintain adequate cardiac output.
Rahimtoola et al. (1970) conducted an observational in Heart disease (n=19). Diagnostic coronary arteriography vs. Baseline (before arteriography) was evaluated on Cardiac performance (including cardiac output, heart rate, stroke volume, and left ventricular filling pressure). Diagnostic coronary arteriography in patients with heart disease caused a temporary increase in left ventricular filling pressure, with no significant change in cardiac output or stroke volume.
