Systolic hypertension in the elderly: controlled or uncontrolled

Area of Science:

• Gerontology
• Cardiovascular Medicine
• Hypertension Research

Background:

• Isolated systolic hypertension (ISH) is defined by systolic blood pressure (SBP) ≥160 mmHg and diastolic blood pressure (DBP) <90 mmHg.
• Its etiology involves reduced arterial elasticity and increased aortic impedance, leading to higher SBP and peripheral resistance.
• ISH prevalence increases with age, affecting approximately 7% of those over 60 and nearly 20% over 80, with higher rates in females and non-whites.

Purpose of the Study:

• To define Isolated Systolic Hypertension (ISH) and its characteristics.
• To outline detection guidelines and management strategies for ISH, particularly in the elderly.
• To discuss the risks associated with ISH and the potential benefits of its control.

Main Methods:

• Review of existing studies on ISH prevalence, etiology, and risk factors.
• Analysis of current guidelines for blood pressure evaluation and ISH detection.
• Discussion of pharmacologic and non-pharmacologic therapeutic approaches for ISH management.

Main Results:

• ISH is associated with a clear risk of stroke, cardiovascular disease (CVD), and premature death, escalating with age and SBP levels.
• Pharmacologic therapies can effectively control ISH, with a target reduction of 20 mmHg in SBP.
• The Systolic Hypertension in the Elderly Program (SHEP) pilot study demonstrated feasibility; the full-scale trial is ongoing.

Conclusions:

• While definitive proof of risk reduction from controlled ISH is pending SHEP trial results, a prudent approach involves non-pharmacologic therapy and pharmacologic agents for high-risk individuals.
• Treatment decisions should be individualized, considering cardiovascular risk burden and symptoms.
• Pharmacologic therapy is generally well-tolerated, with a
