2. Messerli FH, Grossman E, Goldbourt U: Are beta-blockers efficacious as first-line therapy for hypertension in the elderly? A systematic review. JAMA 1998, 279:1903–1907. Meta-analysis of prospective randomized studies in the elderly showed that diuretic therapy was superior to β-blockade with regard to all endpoints, and was effective in preventing cerebrovascular events, fatal stroke, coronary heart disease, cardiovascular mortality, and all-cause mortality. In contrast, β-blocker therapy only reduced the odds for cerebrovascular events, but was ineffective in preventing coronary heart disease, cardiovascular mortality, and all-cause mortality.

3. Medical Research Council trial of treatment of hypertension in older adults: principal results. MRC Working Party. BMJ 1992, 304:405–412. Elderly hypertensive patients were randomized to receive a diuretic, β-blocker, or placebo. The diuretic-treated group had significantly reduced risks of stroke, coronary events, and all cardiovascular events compared with the placebo group. The β-blocker group showed no significant reductions in these endpoints.

Lancet 2002, 359:995–1003. This is a report of the double-masked, randomized, parallel-group trial of 9193 participants aged 55 to 80 years with essential hypertension and LVH ascertained by ECG. Participants were assigned once daily losartan-based or atenolol-based antihypertensive treatment for at least 4 years. Losartan prevented more cardiovascular morbidity and death than atenolol for a similar reduction in blood pressure and was better tolerated.
