[Chronic Reno-Cardial Continuum in Glomerulonephritis]

Area of Science:

• Nephrology
• Cardiology
• Internal Medicine

Background:

• Chronic glomerulonephritis (CGN) significantly increases the risk of cardiovascular pathology.
• Cardiovascular complications are a leading cause of morbidity and mortality in predialysis CGN patients.
• Understanding the specific risk factors is essential for timely intervention.

Purpose of the Study:

• To identify the primary risk factors for cardiovascular pathology in patients with predialysis chronic glomerulonephritis.
• To elucidate the relationship between specific clinical and biochemical markers and cardiovascular disease development.

Main Methods:

• A cohort of 173 predialysis CGN patients (mean age 36.8 years) was studied.
• Clinical examinations included blood pressure, anthropometric measurements, and laboratory tests (cholesterol, creatinine, hemoglobin).
• Instrumental investigations comprised ECG and echocardiography.

Main Results:

• Cardiovascular pathology was present in 88 patients.
• Associated factors included higher serum calcium levels (hypercalcemia), anemia (lower hemoglobin, erythrocyte count/volume), higher serum creatinine, and lower estimated glomerular filtration rate (eGFR).
• Significant differences were noted in calcium, creatinine, and GFR between patients with and without cardiovascular pathology (p<0.05).

Conclusions:

• Anemia, hypercalcemia, and declining kidney function (indicated by increased creatinine and decreased GFR) are major contributors to cardiovascular pathology in predialysis CGN.
• These findings highlight the importance of monitoring and managing these specific parameters to mitigate cardiovascular risk in this patient population.
