[Changes in the cardiac valvular apparatus in patients with end-stage chronic renal failure on long-term programmed...

Area of Science:

• Nephrology
• Cardiology
• Biochemistry

Background:

• Chronic renal failure (CRF) significantly impacts cardiovascular health.
• Programmed hemodialysis is a common treatment for CRF, but its long-term effects on cardiac and bone health require further investigation.
• Understanding the specific sequelae of CRF on heart valves and bone density is crucial for patient management.

Purpose of the Study:

• To investigate the specific features of cardiac valvular diseases in CRF patients undergoing programmed hemodialysis.
• To analyze concurrent biochemical changes in blood composition.
• To assess alterations in bone tissue density in these patients.

Main Methods:

• A study involving 118 patients with CRF, divided into two age groups: 18-40 years (n=69) and 55-73 years (n=49).
• Examination of cardiac valvular status, blood biochemical markers, and bone tissue density.
• Comparative analysis between the younger and older patient cohorts.

Main Results:

• Mitral valvular prolapse/disease was prevalent in younger patients (Group 1), associated with significant phosphorus and calcium metabolic disturbances and elevated parathyroid hormone levels.
• Aortic valvular disease and cardiac tissue calcification were observed in older patients (Group 2).
• These findings highlight age-dependent differences in cardiovascular complications of CRF.

Conclusions:

• The observed patterns of cardiac valvular disease and metabolic changes are characteristic of CRF managed with programmed hemodialysis.
• These conditions represent significant risk factors for developing chronic heart failure, particularly in elderly CRF patients.
• Early identification and management of these risks are essential for improving outcomes in CRF patients.
