Key result
Angina pectoris during cardiac catheterization was associated with impaired augmentation in systolic ejection rate, subnormal increases in cardiac output, and myocardial excess lactate production.

What are the hemodynamic and metabolic changes during an anginal attack in patients undergoing cardiac catheterization?
Angina pectoris is associated with impaired left ventricular systolic ejection rate, subnormal cardiac output increases, and myocardial lactate production, reflecting inadequate myocardial oxygen supply.
Cohen et al. (1965) conducted an observational in Angina pectoris (n=16). Angina pectoris vs. Normal subjects or subjects with coronary artery disease without angina was evaluated on Hemodynamic and metabolic changes (systolic ejection rate, cardiac output, stroke volume, myocardial lactate). Angina pectoris during cardiac catheterization was associated with impaired augmentation in systolic ejection rate, subnormal increases in cardiac output, and myocardial excess lactate production.
