[Microcirculation tolerance for physical loading and homeostatic indices in stenocardia]
Insights
Microcirculatory lesions are common in angina pectoris patients and worsen with chronic coronary insufficiency. These vascular changes impact physical tolerance and blood markers, especially in those lacking typical ECG ischemic shifts.
Area of Science:
- Cardiology
- Microcirculation Research
- Vascular Biology
Background:
- Angina pectoris is associated with significant microcirculatory impairments.
- Conjunctival biomicroscopy reveals widespread vascular lesions in these patients.
Purpose of the Study:
- To investigate the role of microcirculatory lesions in angina pectoris.
- To correlate microcirculatory changes with disease progression and patient outcomes.
Main Methods:
- Utilized conjunctival biomicroscopy to assess microvascular integrity in 80 angina pectoris patients.
- Monitored disease progression, physical strain tolerance, and blood lipid and coagulation parameters.
Main Results:
- Marked extravascular, vascular, and intravascular microcirculatory lesions were observed.
- These lesions progressed with the development of chronic coronary insufficiency.
- Microcirculatory disorders correlated with reduced physical tolerance, elevated cholesterol and triglycerides, and increased blood coagulability.
Conclusions:
- Microcirculatory dysfunction is a key feature of angina pectoris, linked to disease severity and impaired physiological responses.
- In patients without typical ECG ischemic shifts during attacks, microcirculatory disorders play a more significant pathogenetic role.
Abstract:
In 80 patient with angina pectoris marked extravascular, vascular and intravascular microcirculatory lesions have been found through conjunctival biomicroscopy which progressed considerably as chronic coronary insufficiency developed. Disorders in the system of microcirculation in patients with angina pectoris are intimately linked with the decrease of tolerance to physical strain, increase of cholesterol and triglyceride level and the coagulating potential of the blood. In angina pectoris patients who during the anginal attack, caused by physical strain, show no "ischaemic" shift of the S-T segment on the ECG, extra- and intravascular microcirculatory disorders play a relatively greater role in the pathogenesis of the disease than in patients with typical changes on ECG.
