[Functional reserves of blood circulation in aged patients]
Insights
This study analyzed central hemodynamics in elderly patients, revealing a prevalent "hypovolemic" type. Careful assessment of circulation is crucial for older individuals, especially before surgery.
Area of Science:
- Cardiology
- Geriatric Medicine
- Hemodynamics
Background:
- Aging is associated with complex changes in cardiovascular function.
- Assessing central hemodynamics (CH) in the elderly is critical for surgical risk stratification.
- Previous studies have not fully elucidated the spectrum of hemodynamic profiles in this population.
Purpose of the Study:
- To investigate and classify central hemodynamic profiles in elderly patients.
- To identify distinct hemodynamic types based on clinical presentation and pulmonary artery pressures.
- To evaluate the utility of oxygen transport parameters in assessing circulatory reserves.
Main Methods:
- Utilized the Swan-Ganz catheter for invasive hemodynamic monitoring in 43 elderly patients (mean age 72.4 years).
- Classified patients into hemodynamic types based on clinical picture, blood flow, and pulmonary artery jamming pressure.
- Incorporated oxygen transport system parameters for supplementary data analysis.
Main Results:
- Identified several distinct hemodynamic types, with the "hypovolemic" variant being most prevalent (n=17).
- Other identified types included eukinetic (n=8), hyperkinetic (n=7), and hypokinetic (n=2).
- Patients with limited circulatory reserves were identified, necessitating preoperative management.
Conclusions:
- The elderly exhibit diverse central hemodynamic profiles, requiring a meticulous approach to assessment.
- Preoperative identification and management of hemodynamic disorders are recommended for this age group.
- A scrupulous evaluation of circulatory condition and reserves is essential in geriatric patients.
Abstract:
Central hemodynamics (CH) were studied in 43 elderly (72.4 years) patients by means of the Swan-Ganz catheter. Analysis according to three main criteria--the clinical picture and the values of volume blood flow and jamming pressure in the pulmonary artery--disclosed several hemodynamic types. The "hypovolemic" CH variant was prevalent (17), the eukinetic type of CH was encountered in 8, the "hyperkinetic" type--in 7, and the "hypokinetic" type--in 2 patients. Some parameters of the system of oxygen transport were used as additional information. Patients with limited reserves of circulation were set apart. Additional preoperative management for correcting CH disorders was recommended for them. It is concluded that the approach to the appraisal of the condition and reserves of circulation in the elderly must be more scrupulous.
