[Central hemodynamics and microcirculation and their interrelation in hypertension]

Area of Science:

• Cardiovascular Medicine
• Hypertension Research
• Hemodynamics

Background:

• Hypertensive disease is a significant global health concern.
• Understanding central and microcirculatory haemodynamics is crucial for managing hypertension.
• Previous research has explored various haemodynamic parameters in hypertensive patients.

Purpose of the Study:

• To examine central haemodynamics and microcirculation in patients with hypertensive disease.
• To identify haemodynamic variants and their frequency across different stages of hypertension.
• To investigate the correlation between peripheral resistance and microcirculatory vascular changes.

Main Methods:

• Mechanocardiography for assessing central haemodynamics.
• Conjunctival biomicroscopy for evaluating microcirculation.
• Study included 237 patients diagnosed with hypertensive disease.

Main Results:

• A high level of peripheral resistance was observed in relation to minute blood volume in patients with hypertensive disease.
• The primary haemodynamic variants occurred with similar frequency across all stages of the disease.
• A direct correlation was found between peripheral resistance values and vascular microcirculatory changes.

Conclusions:

• Elevated peripheral resistance is a key feature in hypertensive disease, irrespective of disease stage.
• Microcirculatory vascular changes are directly associated with peripheral resistance levels in hypertension.
• These findings highlight the interconnectedness of central and microcirculatory haemodynamics in hypertension management.
