Lifestyle changes may be more important than drugs for mild hypertension

Area of Science:

• Cardiovascular Medicine
• Pharmacology
• Public Health

Background:

• Mild hypertension is common, but the benefits of pharmacological treatment in low-risk individuals remain debated.
• Existing guidelines vary on the threshold for initiating antihypertensive therapy.
• Understanding the benefit-harm balance is crucial for clinical decision-making.

Purpose of the Study:

• To evaluate the benefits and harms of antihypertensive drug treatment in patients with mild hypertension and low cardiovascular risk.
• To inform clinical practice regarding the management of mild hypertension.

Main Methods:

• Systematic review and meta-analysis of randomized controlled trials.
• Inclusion of studies focusing on patients with mild hypertension (systolic blood pressure 130-139 mmHg or diastolic 80-89 mmHg) and low cardiovascular risk.
• Assessment of cardiovascular events, mortality, and adverse effects.

Main Results:

• Antihypertensive treatment showed a small reduction in systolic blood pressure but did not significantly decrease major adverse cardiovascular events or mortality.
• Increased risk of adverse events, including hypotension and electrolyte disturbances, was observed with drug treatment.
• The absolute benefit in preventing cardiovascular events was minimal in this low-risk population.

Conclusions:

• For patients with mild hypertension and low cardiovascular risk, the benefits of antihypertensive drug treatment are unlikely to outweigh the potential harms.
• Lifestyle modifications should be prioritized as the first-line management strategy.
• Further research may be needed to refine treatment thresholds and identify subgroups who might benefit more from pharmacological intervention.
