To evaluate potential disorders of regional myocardial blood flow in patients presenting with chest pain syndromes despite normal coronary arteriograms.
Assessed 21 patients categorized into three clinical groups: classic angina (n=7), mixed typical and atypical pain (n=7), and entirely atypical pain (n=7).
Measured regional myocardial blood flow using intracoronary Xenon-133 injections, re-evaluating 13 patients during glyceryl trinitrate administration (n=6) or contrast agent-induced hyperaemia (n=7).
Resting regional myocardial blood flow showed wide inter-individual variability, ranging from 41 to 128 ml/min per 100 g, with an overall mean of 77 ± 7 ml/min per 100 g (mean ± SEM).
No statistically significant differences in regional myocardial blood flow occurred among the three chest pain groups.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Physiological study finds uniform myocardial blood flow across diverse chest pain syndromes with normal coronary arteriograms, indicating resting blood delivery does not explain pain patterns.
