Key result
Cigarette smoking in patients without heart disease resulted in a significant rise in coronary blood flow and heart rate, and a significant decline in coronary vascular resistance.

Indicates no acute coronary constriction from smoking; leaves open translation to outcomes and metabolism in larger studies.
Observational
Does cigarette smoking alter coronary blood flow and myocardial metabolism in patients without heart disease?
Acute cigarette smoking in patients without heart disease increases coronary blood flow and decreases coronary vascular resistance, showing no evidence of acute coronary constriction.
Bargeron et al. (1957) conducted an observational in Without heart disease. Cigarette smoking was evaluated on Coronary blood flow, heart rate, coronary vascular resistance, and myocardial extraction of oxygen and glucose. Cigarette smoking in patients without heart disease resulted in a significant rise in coronary blood flow and heart rate, and a significant decline in coronary vascular resistance.
