Blood pressure behaviour in hemodialysis patients treated for 10 years
Insights
Long-term hemodialysis can significantly reduce hypertension in patients. While blood pressure often improves, electrocardiogram abnormalities may increase over time in these dialysis patients.
Area of Science:
- Nephrology
- Cardiology
- Internal Medicine
Background:
- Hypertension is a common comorbidity in patients undergoing hemodialysis.
- Long-term outcomes and the natural history of hypertension in this population require further clarification.
Purpose of the Study:
- To analyze the long-term changes in blood pressure and associated factors in patients undergoing hemodialysis for at least 10 years.
- To understand the prevalence and characteristics of hypertension in long-term hemodialysis survivors.
Main Methods:
- Longitudinal analysis of blood pressure data in 30 patients on hemodialysis for over 10 years.
- Assessment of clinical and metabolic parameters, including body weight, hematocrit, and electrocardiogram (ECG) abnormalities.
Main Results:
- Prevalence of hypertension decreased from 73.3% before dialysis to 16.6% after 10 years.
- Hypertension resolved in younger patients; older patients showed persistent or new-onset systolic hypertension.
- Body weight tended to decrease progressively; hematocrit was the only metabolic parameter with significant differences.
- ECG abnormalities were more frequent after 10 years of dialysis compared to baseline.
Conclusions:
- Hypertension tends to resolve progressively in hemodialysis patients over the long term.
- While blood pressure may improve, increased ECG abnormalities are noted in long-term hemodialysis survivors.
- Age and systolic hypertension characteristics are important factors in long-term dialysis patient outcomes.
Abstract:
A longitudinal analysis of blood pressure was performed in 30 patients on hemodialysis for at least 10 years, in order to clarify the long-term outcome of hypertension in dialysis patients. Before the start of the dialysis treatment 22 (73.3%) patients were hypertensive, while, after 10 years, only 5 (16.6%) were still hypertensive. Body weight tended to decrease progressively throughout the period of observation. Hypertension disappeared in the younger patients while it remained/appeared in those who were order showing the characteristics of systolic hypertension. Except for hematocrit no significant differences in metabolic findings were found between normotensive and hypertensive patients. ECG abnormalities were found to be more frequent after 10 years of dialysis than before the start of treatment. High blood pressure tends to disappear progressively in hemodialysis patients and to be no longer a problem in long-term survivors.
