[Modification of coronary sinus in patients with chronic cardiac insufficiency]
Insights
Changes in the cardiac venous system (CVS) are crucial in chronic cardiac insufficiency (CCI). This study reveals significant variations in the coronary sinus (CS) state based on CCI stage, highlighting the need for comprehensive CVS evaluation.
Area of Science:
- Cardiology
- Vascular Biology
- Medical Imaging
Background:
- Morphofunctional changes in both arterial and venous systems occur in cardiovascular diseases.
- The cardiac venous system (CVS) is increasingly recognized for its role in chronic cardiac insufficiency (CCI).
- Limited research has focused on the CVS, despite its potential significance.
Purpose of the Study:
- To investigate the morphofunctional changes in the cardiac venous system (CVS) of patients with chronic cardiac insufficiency (CCI).
- To compare the state of the coronary sinus (CS) in CCI patients across different disease stages with healthy individuals.
- To emphasize the necessity of comprehensive CVS assessment in managing CCI.
Main Methods:
- Doppler echocardiography (echo-CG) was used to examine the CVS in 160 patients.
- Spiral computed tomography (CT) was employed for CVS assessment in 41 patients.
- Patients were stratified into three groups based on CCI stage (IIA, IIB, III) and functional class (III-IV).
Main Results:
- Significant variations in the coronary sinus (CS) state were observed correlating with the stage of chronic cardiac insufficiency (CCI).
- The findings indicate a dynamic relationship between CCI progression and alterations within the cardiac venous system.
- The study provides evidence that the CVS is a key component affected by CCI.
Conclusions:
- The cardiac venous system (CVS) undergoes significant changes in patients with chronic cardiac insufficiency (CCI).
- The state of the coronary sinus (CS) varies considerably depending on the severity of CCI.
- Comprehensive evaluation of the CVS using all available methods is essential for patients with CCI.
Abstract:
Both venous and arterial beds undergo a number of morphofunctional changes in patients with cardiovascular pathology, but they rarely attract attention of researchers. The available data indicate that the cardiac venous system (CVS) plays an important role in the development of chronic cardiac insufficiency (CCI) and dictate the necessity of its in-depth studies. We examined CVS in 160 patients by Doppler echo-CG and in 41 ones by spiral CT. The patients were allocated to 3 groups depending on the stage of CCI (IIA, IIB and III stages, III-IV functional class). The state of their coronary sinus (CS) was compared with that of healthy subjects. The state of CS varied considerably depending on the stage of CCI. It is concluded that patients with CCI need their CVS to be studied by all available methods.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...
