Insights
Patients undergoing chronic hemodialysis exhibit a high prevalence of cardiovascular risk factors, specifically elevated blood pressure and low HDL cholesterol. These findings highlight critical areas for intervention in this vulnerable population.
Area of Science:
- Nephrology
- Cardiology
- Nutritional Science
Background:
- Patients undergoing chronic hemodialysis face a significant risk of mortality, primarily due to cardiovascular diseases.
- Identifying and managing cardiovascular risk factors is crucial for improving outcomes in this population.
Purpose of the Study:
- To investigate the prevalence of cardiovascular risk factors.
- To assess the nutritional status among patients receiving maintenance hemodialysis.
Main Methods:
- Evaluated 15 patients (8 male) undergoing maintenance hemodialysis.
- Measured body mass index, blood pressure, serum lipid profiles (total cholesterol, HDL cholesterol, triglycerides), and albumin levels.
- Compared findings with data from the general Chilean population.
Main Results:
- A high frequency of hypertension (87%) and low HDL cholesterol (<35 mg/dl in all patients) was observed.
- Prevalence of hypercholesterolemia (total cholesterol >200 mg/dl) was 27%, and elevated triglycerides (>200 mg/dl) was present in three patients.
- Mean body mass index was normal, with albumin levels indicating adequate nutritional status, contrasting sharply with higher population rates of hypertension and smoking.
Conclusions:
- Patients in maintenance hemodialysis demonstrate a high occurrence of hypertension and low HDL cholesterol.
- These cardiovascular risk factors are significantly more prevalent in this group compared to the general population, underscoring the need for targeted management strategies.
Background:
Patients in chronic hemodialysis have a high mortality due to cardiovascular diseases.
Aim:
To study cardiovascular risk factors and nutritional status in a group of patients in maintenance hemodialysis.
Patients And Methods:
Body mass index, blood pressure, serum levels of totals cholesterol, HDL cholesterol, triglycerides and albumin were measured in 15 patients (8 male) in maintenance hemodialysis. Data were compared with available figures for the normal Chilean population.
Results:
Age ranged from 33 to 60 years old in female patients and from 22 to 63 years old in males. Thirteen subjects (87%) had high blood pressure, all had HDL cholesterol levels below 35 mg/dl, four (27%) had a total cholesterol over 200 mg/dl, three had triglyceride levels over 200 m/dl, two (13%) smoked and none were diabetic. Mean body mass index was normal, albumin levels were 4.16 and 4.02 g/dl and serum creatinine was 11.64 and 9.68 mg/dl in males and females respectively. The estimated prevalence of high blood pressure, hypercholesterolemia and smoking in the general Chilean population range from 9 to 22%, from 50 to 52% and from 45 to 51% respectively.
Conclusions:
This group of patients has a high frequency of high blood pressure and low HDL cholesterol levels.
