[Arterial hypertension, aging and cardiac decompensation]

Area of Science:

• Cardiology
• Gerontology
• Vascular Medicine

Background:

• Hypertensive patients often exhibit normal or enhanced cardiac function despite hypertrophy.
• The transition from compensated to decompensated hypertensive heart failure is poorly understood.
• Cardiovascular aging may independently trigger decompensation through specific hemodynamic effects.

Purpose of the Study:

• To explore the mechanisms of decompensation in hypertensive heart failure.
• To investigate the role of cardiovascular aging in hypertensive heart failure.
• To highlight the importance of arterial function evaluation in cardiac failure.

Main Methods:

• Review of existing arguments and data on cardiovascular aging and hypertension.
• Analysis of cardiac fibrosis and its impact on diastolic function and arrhythmias.
• Examination of aortic rigidity and its dissociation of cardiac and vascular functions.

Main Results:

• Cardiac fibrosis can impair diastolic expansion and promote arrhythmias.
• Increased aortic rigidity shifts pressure wave reflections to systole, affecting cardiac function.
• These age-related vascular changes contribute to hypertensive heart failure decompensation.

Conclusions:

• Cardiovascular aging plays a significant role in hypertensive heart failure decompensation.
• Arterial function assessment, using noninvasive techniques, is essential for evaluating cardiac failure.
• Understanding these mechanisms can improve clinical management of hypertensive heart disease.
