[Interrelationship between the basic parameters of hemo- and cardiodynamics in hypertension patients]
Insights
This study identified four hemodynamic types in hypertensive patients: hyperkinetic, hypokinetic, mixed, and normokinetic. The mixed and hypokinetic variants showed the most significant cardiac and blood supply impairments compared to normal parameters.
Area of Science:
- Cardiology
- Physiology
- Medical Diagnostics
Background:
- Hypertensive disease affects hemodynamics.
- Understanding hemodynamic variations is crucial for patient management.
Purpose of the Study:
- To classify hemodynamic patterns in hypertensive patients.
- To identify characteristic signs for each hemodynamic type.
- To compare hemodynamic alterations across different variants and with normal parameters.
Main Methods:
- Mechanocardiography
- Aorta and lung rheography
- Rheovasography, hepatography, and encephalography
- Polycardiography
- Examination of 541 hypertensive patients and 98 healthy individuals.
Main Results:
- Four distinct hemodynamic types were identified: hyperkinetic, hypokinetic, mixed, and normokinetic.
- Each type exhibited unique clinical signs.
- Mixed and hypokinetic variants showed the most pronounced changes in myocardial contractility and blood supply to organs (liver, brain, limbs) compared to normal age parameters.
Conclusions:
- The classification of hemodynamic variants provides a framework for understanding hypertensive disease.
- Hemodynamic profiling can aid in assessing the severity of cardiac and circulatory dysfunction in hypertension.
- Specific hemodynamic patterns correlate with distinct patterns of organ blood supply impairment.
Abstract:
In examination of 541 patients with hypertensive disease and 98 practically healthy persons by means of mechanocardiography, rheography of the aorta and lung, rheovaso-, hepato-, and encephalography, and encephalography, and polycardiography, 4 types of disturbed hemodynamics were distinguished: hyperkinetic, hypokinetic, mixed, and normokinetic. Each type has characteristic signs distinguishing it from the other types and from the normal age parameters. Compared to the normal age parameters the changes in the parameters of the contractive function of the right and left ventricular myocardium and the disorders of blood supply to the liver, brain, and limbs are the most marked in the mixed and hypokinetic hemodynamic variant and less in the normokinetic hemodynamic variant.
