Large arteries in hypertension. Pharmacological and therapeutic aspects
1Hôpital Broussais, Paris, France.
Insights
Pulse pressure, a key component of blood pressure, is often overlooked in hypertension treatment. This review analyzes factors influencing pulse pressure and discusses pharmacological agents for its selective reduction, particularly in elderly systolic hypertension.
Area of Science:
- Cardiovascular Physiology
- Pharmacology
- Geriatric Medicine
Background:
- Blood pressure has two components: steady mean arterial pressure and pulsatile pulse pressure.
- Current hypertension treatments primarily target mean arterial pressure, neglecting pulse pressure.
- Elevated pulse pressure is a hallmark of elderly systolic hypertension and predicts cardiac mortality.
Purpose of the Study:
- To analyze the factors influencing pulse pressure.
- To review pharmacological agents that can selectively reduce pulse pressure.
- To address the therapeutic gap in managing pulse pressure in hypertension.
Main Methods:
- Literature review and analysis of hemodynamic factors.
- Examination of existing pharmacological interventions for hypertension.
- Synthesis of data on agents affecting pulse pressure.
Main Results:
- Identified key determinants of pulse pressure.
- Reviewed various drug classes with potential to lower pulse pressure.
- Highlighted the significance of pulse pressure in cardiovascular risk assessment.
Conclusions:
- Pulse pressure is a critical, yet undertreated, hemodynamic parameter.
- Selective reduction of pulse pressure may improve outcomes in specific hypertensive populations.
- Further research into targeted therapies for pulse pressure is warranted.
Abstract:
The blood pressure curve may be divided into two components: mean arterial pressure, the steady component, and pulse pressure, the pulsatile component. Whereas pharmacological interventions in hypertension have been focused mainly on mean arterial pressure, little has been done to reduce selectively pulse pressure. However, increased pulse pressure with nearly normal mean arterial pressure is the classical hallmark of systolic hypertension in the elderly and a strong independent predictor of cardiac mortality, mainly for myocardial infarction. In this report, after the analysis of the factors influencing pulse pressure, a review of the pharmacological agents susceptible to reduce this hemodynamic factor is performed.
