Optimising drug management of individuals with cryptogenic hypertension
1Department of Medicine, National University Hospital, Singapore.
Insights
Treating mild hypertension with sequential monotherapy or drug combinations lowers vascular event deaths. Tailoring treatment to individual patient profiles and conditions ensures optimal outcomes and adherence.
Area of Science:
- Cardiology
- Pharmacology
- Public Health
Background:
- Mild hypertension (diastolic blood pressure 90-104 mm Hg) management is crucial for reducing mortality from stroke and non-coronary vascular events.
- Sequential monotherapy with the lowest effective dose is the optimal initial strategy, with drug combinations available as an alternative.
Purpose of the Study:
- To outline evidence-based strategies for drug treatment in mild hypertension.
- To provide guidance on selecting antihypertensive medications based on patient characteristics and comorbidities.
Main Methods:
- Review of existing literature and clinical guidelines on hypertension management.
- Analysis of drug efficacy and safety profiles for different patient subgroups.
Main Results:
- Beta-adrenoceptor blockers or low-dose thiazides are cost-effective options for many patients.
- Specific patient groups benefit from particular drug classes: beta-blockers for young men, post-MI patients, and renal failure; thiazides or calcium channel blockers for older adults, women, smokers, stroke victims, and liver disease patients.
- Diuretics should be avoided in pregnant women and those with untreated gout. Calcium channel blockers and ACE inhibitors are preferred for diabetes and renal failure; angiotensin manipulators or thiazides for heart failure and peripheral vascular disease.
Conclusions:
- Individualized drug treatment selection is paramount, considering patient's overall condition, age, and concurrent diseases or medications.
- The target diastolic pressure is 85-89 mm Hg, with necessary compromises for specific populations like the elderly or poorly motivated young men.
- Adherence to treatment is vital for achieving therapeutic goals and preventing adverse outcomes.
Abstract:
Regular drug treatment in mild hypertension (diastolic blood pressure 90-104 mm Hg) reduces death from stroke, and other non-coronary vascular events. The optimum strategy remains sequential monotherapy with the lowest effective dose, with drug combinations as an option. A beta-adrenoceptor blocker or low-dose thiazide is good value treatment for many patients. beta-Blockers are good for young (under 50 years), anxious non-smoking men, men after myocardial infarction, and renal failure patients. Older persons over about 65 years, women, smokers, stroke victims, and liver disease patients should generally take a thiazide or calcium ion-channel blocker. Pregnant women and untreated gouty patients should avoid diuretics. Calcium blockers and angiotensin-converting enzyme inhibitors are preferable in severe or insulin-dependent diabetes and renal failure, and angiotensin manipulators or thiazides in heart failure or peripheral vessel disease. Hyperlipidaemia should not generally exclude thiazides or beta-blockers. Some hypertensive stroke patients without encephalopathy may not need antihypertensive drug treatment for the first 24-48 hours. Drug treatment should be tailored to individuals according to their general condition, physiological age, and any concurrent disease or medication. Unwanted drug reactions should not deter patients from fulfilling social and economic goals. The desired treatment end-point is a diastolic pressure of 85-89 mm Hg, but a compromise is usual in poorly motivated young men, and the elderly.
