Women taking a calcium channel blocker were 74% MORE likely to die of cardiovascular disease during a 5.9 year follow-up than women taking NO blood pressure drugs even though the average systolic pressure was 10 points LOWER in the drug group than the no drug group (139 mm Hg vs 149 mm Hg) according to a 2004 study.

To say this the other way, women taking NO blood pressure medicines were 43% LESS likely to die of cardiovascular disease during the 5.9 year follow-up than women taking a calcium channel blocker.
