Caffeine gets the blame for raising blood pressure, but the disparity between espresso and pure caffeine suggests there is more to the story.

The decaffeinated espresso proved the point. It did not raise blood caffeine levels, but it boosted the average systolic blood pressure of the nondrinkers by 12 mm Hg, virtually as much as the high-test brew. The study helps explain why earlier investigations produced such variable results.

Coffee does raise blood pressure in people who are not used to it but not in regular coffee drinkers; youngsters appear more sensitive to coffee.

And the hypertensive effects of coffee seem to depend on ingredients other than caffeine. Habitual coffee drinkers become acclimated to these ingredients so their pressures don't rise more than a point or two, but people who are not used to coffee can expect a temporary rise in their pressures after drinking regular or decaf.

Blood pressure is an important predictor of heart attack and stroke. Even if coffee doesn't raise blood pressure in regular drinkers, does it live up to its reputation as a cause of heart disease?

In a two-year study of 45, men between the ages of 40 and 75, Harvard scientists found no link between coffee consumption and the risk of coronary artery disease or stroke, even in heavy drinkers.

But while regular coffee proved harmless, decaf was associated with a slightly increased risk of heart disease, though the link was weak.

The Scottish Heart Health Study was even more reassuring, reporting a reduced risk of heart disease in coffee drinkers, with heavy drinkers getting the most benefit. And although some coffee drinkers are annoyed by a feeling of rapid pulse, coffee does not seem to cause serious disorders of the heart's rhythm, even in recent heart attack patients.

Coffee is a complex brew, and it has many effects beyond the cardiovascular system. Some people benefit from increased alertness, but for others the neurological actions of coffee include insomnia, anxiety, or tremors.
