Review Meta AnalysisEffects of blood pressure-lowering treatment on cardiovascular outcomes and mortality: 14 - effects of different classes of antihypertensive drugs in older and younger patients: overview and meta-analysis.
The five major classes of blood pressure (BP)-lowering drugs have all been shown to significantly reduce the risk of major cardiovascular events when compared with placebo, and when directly (head-to-head) compared, no significant differences in their overall effectiveness have been detected, except for minor differences in cause-specific events. It is unknown, however, whether age-related differences exist and if some classes of drugs are differently effective in older or younger individuals. This clinically relevant question has been the object of a systematic search and meta-analysis of all available data. ⋯ Most BP-lowering classes are equally effective in preventing risk of fatal and nonfatal cardiovascular events both in older and younger patients, whereas beta-blockers, though being equally effective as the other agents in patients younger than 65, loose some of their effectiveness at an older age.

Review Meta AnalysisEffects of blood pressure-lowering treatment on cardiovascular outcomes and mortality: 13 - benefits and adverse events in older and younger patients with hypertension: overview, meta-analyses and meta-regression analyses of randomized trials.
There is overwhelming evidence that blood pressure (BP)-lowering treatment can reduce cardiovascular outcomes also in the elderly, but some important aspects influencing medical practice are controversial as sufficient evidence has not been provided by single randomized controlled trials (RCTs), whereas evidence may result from a systematic search and meta-analysis of all available data. ⋯ Antihypertensive treatment should be recommended to all individuals with elevated BP, independent of age. The prudent recommendation to initiate treatment at SBP values 140-159 mmHg is supported at older age defined as greater than 60 years. SBP and DBP values lower than 140 mmHg and, respectively, 80 mmHg can be aimed at with incremental benefits without disproportionate burdens until age 80 years, above which available evidence is for benefits at on-treatment SBP 140-149 mmHg.
