“…230,234–237 In one of these
meta-analyses evaluating different classes of agents used as first-line therapy
in subjects with a baseline BP >140/90 mm Hg, thiazide diuretics (RR,
0.63; 95% CI, 0.57–0.71), β-blockers (RR, 0.83;
95% CI, 0.72–0.97), ACEIs (RR, 0.65; 95% CI,
0.52–0.82), and calcium channel blockers (RR, 0.58; 95% CI,
0.41–0.84) each reduced the risk of stroke compared with placebo or no
treatment. 236
Compared with thiazides, β-blockers, ACEIs, and ARBs, calcium channel
blockers appear to have a slightly greater effect on reducing the risk of
stroke, although the effect is not seen for other cardiovascular outcomes and
was of small magnitude (8% relative reduction in risk). 235 One meta-analysis found that
diuretic therapy was superior to ACEI therapy, 230 and another found that calcium channel
blockers were superior to ACEIs.…”
