Why the study?
Does diving cause a more powerful coronary vasoconstriction compared to the cold pressor test in subjects with mild and severe left coronary artery disease?
Population
22 subjects with angiographically documented mild or severe left anterior descending coronary artery stenosis
Comparison
Diving stimulus (45 seconds) vs Cold pressor test (2 minutes)
Design
Cross-sectional

May support diving as vasoconstrictor stimulus in CAD research; leaves open its diagnostic superiority pending prospective validation.
Does diving cause a more powerful coronary vasoconstriction compared to the cold pressor test in subjects with mild and severe left coronary artery disease?
Diving is a more powerful coronary vasoconstrictor stimulus than the cold pressor test and may be a superior diagnostic maneuver for investigating coronary vascular regulation.
Saino et al. (1992) studied this question.
