Reflex increase in blood pressure during the intracoronary administration of adenosine in man. However, potential mechanisms underlying these effects are unclear.
Part of this complexity is that long term caffeine may tend to lower sodium and therefore water in a diuretic effect that would be expected to lower blood pressure.
