High blood pressure with elevated resting heart rate: a high risk "Sympathetic" clinical phenotype

Area of Science:

• Cardiology
• Hypertension Research
• Clinical Physiology

Background:

• Elevated resting heart rate (RHR) is linked to adverse prognosis in hypertensive individuals.
• Recent data reinforce RHR's clinical significance as a specific hypertensive phenotype.
• Resting tachycardia in hypertension is associated with increased cardiovascular event and complication risk.

Purpose of the Study:

• To review existing and new data on the prognostic importance of RHR in hypertensive patients.
• To examine the role of the sympathetic nervous system in resting tachycardia associated with hypertension.
• To discuss therapeutic implications and dynamic assessment methods for RHR in clinical settings.

Main Methods:

• Systematic literature review of epidemiological and clinical studies.
• Analysis of data on resting heart rate, hypertension, and cardiovascular outcomes.
• Exploration of the sympathetic nervous system's involvement and therapeutic interventions.

Main Results:

• Consistent evidence supports the adverse prognostic impact of elevated RHR in hypertension.
• Resting tachycardia is increasingly recognized as a distinct phenotype within hypertension.
• Sympathetic nervous system activity plays a key role in the development of this condition.

Conclusions:

• Elevated RHR is a significant independent predictor of cardiovascular events in hypertensive patients.
• Understanding resting tachycardia as a hypertensive phenotype guides risk stratification and management.
• Further research into therapeutic strategies targeting RHR in hypertension is warranted.
