Tachycardia: The hidden cardiovascular risk factor in uncomplicated arterial hypertension

Area of Science:

• Cardiology
• Hypertension Research
• Preventive Medicine

Background:

• Elevated blood pressure management is key to reducing cardiovascular disease (CVD) burden.
• European hypertension guidelines emphasize risk assessment and stratification.
• Elevated heart rate (HR) is a significant predictor of various adverse health outcomes, including hypertension, CVD, and mortality.

Purpose of the Study:

• To review the pathophysiology of early hypertension, focusing on sympathetic nervous system activation.
• To discuss the prognostic significance of elevated HR.
• To explore the rationale for HR lowering strategies in managing hypertension.

Main Methods:

• Literature review of hypertension pathophysiology and risk factors.
• Analysis of the role of sympathetic nervous system activation in hypertension.
• Examination of the prognostic value of elevated HR.
• Review of non-pharmacological and pharmacological (beta-blockers) HR-lowering approaches.

Main Results:

• Sympathetic nervous system activation plays a critical role in early hypertension.
• Fast HR is a significant predictor of future cardiovascular events and mortality.
• Resting HR is easily measurable and modifiable through lifestyle or medication.

Conclusions:

• Lowering resting HR is a potential strategy to reduce disease burden and premature mortality.
• Further outcome studies are needed to confirm the benefits of HR lowering in tachycardia-related hypertension.
• Highly long-acting cardioselective beta-blockers, like betaxolol, may be considered for HR management.
