[Renal dysfunction and anemia in old patients with diastolic cardiac failure]
Insights
Anemia and reduced kidney function in elderly patients with chronic diastolic cardiac failure (CDCF) worsen symptoms and impact left ventricular diastolic filling. Lower glomerular filtration rate (GFR) prolongs relaxation, while lower hemoglobin increases early filling velocity.
Area of Science:
- Cardiology
- Nephrology
- Geriatrics
Context:
- Chronic diastolic cardiac failure (CDCF) affects elderly individuals.
- Renal insufficiency and anemia are common comorbidities in this population.
- Diastolic dysfunction significantly impacts cardiac function and patient outcomes.
Purpose:
- To investigate the influence of renal functional insufficiency and anemia on clinical presentation and left ventricular diastolic filling in elderly patients with CDCF.
- To determine the relationship between glomerular filtration rate (GFR), hemoglobin levels, and diastolic function parameters.
Summary:
- The study examined 116 elderly patients with CDCF, assessing renal function (GFR) and anemia.
- A significant percentage of patients had reduced GFR (36.2%) and anemia (28.4%), with a notable overlap (18.1%).
- Results indicated a direct correlation between hemoglobin and GFR, and that reduced GFR prolonged isovolumic relaxation time, while lower hemoglobin increased early diastolic filling velocity.
Impact:
- Findings highlight the critical role of renal function and anemia in modulating diastolic function in elderly CDCF patients.
- This underscores the importance of managing these comorbidities to improve clinical outcomes.
- The study provides insights into the complex interplay of factors affecting diastolic filling in this vulnerable group.
Aim:
To study the effects of renal functional insufficiency and anemia on clinical symptoms and diastolic filling of the left ventricle in aged patients with chronic diastolic cardiac failure (CDCF).
Material And Methods:
We examined 116 patients (69 females, 47 males) with CDCF (ejection fraction > 45%) of functional class I-IV aged 65-86 (76.4 +/- 5.2) years. Anemia was diagnosed in men with hemoglobin under 130 g/l, in women--under 120 g/l. Glomerular filtration rate (GFR) was calculated by Cockcroft- Gault formula.
Results:
GFR < 60 ml/min/1.73 m2 was observed in 42 (36.2%) patients; anemia--in 33 (28.4%) patients, combination of anemia with subnormal renal function--in 21 (18.1%). Left ventricular hypertrophy was diagnosed in 101 (87.1) patients. Type of transmitral circulation with impaired relaxation, pseudonormal and restrictive was detected in 80 (69%), 29 (25%) and 7 (6%) patients, respectively. There is a direct correlation between hemoglobin content and GFR (r = 0.33; p < 0.01). Functional class of CDCF in anemic patients and anemia combination with subnormal GFR was higher than in patients free of anemia. It was established that the less GFR rate is the longer is the time of isovolumic relaxation of the left ventricle; the lower hemoglobin the greater is the velocity of early diastolic filling.
Conclusion:
In aged patients with CDCF diastolic filling depends not only on age, heart rate, structural changes of the heart but also on reduced renal function, anemia, systolic arterial pressure.
