Hypertension Management in Elderly Women

Recommended Treatment Approach

The American College of Cardiology recommends starting with a thiazide-like diuretic, such as chlorthalidone 12.5 mg daily, or a dihydropyridine calcium channel blocker, such as amlodipine 5 mg daily, as first-line therapy for elderly women with stage 1 hypertension, with a slight preference for the thiazide-like diuretic based on the strongest mortality and stroke reduction data in elderly women 1
The European Society of Cardiology recommends calcium channel blockers for patients ≥55 years as first-line therapy, particularly for those with isolated systolic hypertension 3
Chlorthalidone 12.5-25 mg daily is the preferred first-line agent based on proven cardiovascular outcomes and mortality reduction in elderly patients, particularly women, with a significant reduction in coronary heart disease, stroke, cardiovascular events, and all-cause mortality 1
The SHEP trial demonstrated significant stroke reduction when treating to SBP <140 mmHg in elderly women with a mean age of 72 years 2

The American College of Cardiology recommends targeting BP <140/90 mmHg as the primary goal for elderly patients with stage 1 hypertension, with a consideration for targeting <130/80 mmHg in those with high cardiovascular risk 2, 4, 6
Treating to SBP <140 mmHg provides greater public health protection against cardiovascular disease in older women with little evidence of serious harm 2

The European Society of Cardiology recommends starting with monotherapy and titrating gradually to achieve target blood pressure control within 3 months of initiating therapy 3, 7
The American College of Cardiology recommends checking blood pressure in both sitting and standing positions due to increased orthostatic hypotension risk in elderly patients, and monitoring potassium and creatinine at baseline and 1-2 weeks after starting thiazide diuretics 4, 6

The European Society of Cardiology recommends monitoring blood pressure every 4-6 months once BP is controlled and stable, and checking electrolytes and renal function regularly in patients taking thiazide diuretics 1, 3
Hypokalemia below 3.5 mEq/L eliminates cardiovascular protection and increases sudden death risk, making electrolyte monitoring essential 3

The European Society of Cardiology recommends reserving ACE inhibitors or ARBs for patients with specific compelling indications such as diabetes, chronic kidney disease with albuminuria, or heart failure 5, 6, 8
Beta-blockers are inferior to thiazides and calcium channel blockers for stroke prevention and cardiovascular events in elderly patients without specific indications (prior MI, heart failure, active angina) 4, 5

The American College of Cardiology recommends avoiding high-dose thiazides (>25 mg chlorthalidone) as they provide minimal additional BP reduction but substantially increase adverse effects, particularly hypokalemia requiring hospitalization 3
The European Society of Cardiology recommends avoiding starting with combination therapy in patients with BP 140/84 mmHg; single-agent therapy is appropriate for BP between 130/80 and 160/100 mmHg 8
