Background

Left ventricular hypertrophy (LVH) is a common condition among patients with end-stage kidney failure, with a prevalence of more than 80% in patients undergoing dialysis. The process of hypertrophy is not only influenced by hemodynamic factors, but also non-hemodynamic factors. One condition that is often found in kidney failure patients is dyslipidemia, which is related to lipid metabolic problems. In general populations, dyslipidemia, including abnormal lipid levels, can be associated with LVH. However, the relationship between dyslipidemia and LVH in patients undergoing hemodialysis is still not completely clear.

Understanding the Complexity of Left Ventricular Hypertrophy

Left ventricular hypertrophy (LVH) is a condition where the muscle wall of the left ventricle becomes thickened, which can lead to heart failure and other complications. In patients with end-stage kidney failure, LVH is a common condition, affecting more than 80% of patients undergoing dialysis. The process of hypertrophy is influenced by both hemodynamic and non-hemodynamic factors. Hemodynamic factors, such as high blood pressure, can contribute to the development of LVH. Non-hemodynamic factors, such as dyslipidemia, can also play a role in the development of LVH.

The Role of Dyslipidemia in Left Ventricular Hypertrophy

Dyslipidemia, or abnormal lipid levels, is a common condition in patients with kidney failure. In general populations, dyslipidemia has been associated with an increased risk of cardiovascular disease, including LVH. However, the relationship between dyslipidemia and LVH in patients undergoing hemodialysis is still not completely clear. This study aims to evaluate the relationship between lipid profiles and left ventricular mass index (LVMI) in patients with chronic kidney failure undergoing hemodialysis.

Research Purposes

This study aims to evaluate the relationship between lipid profiles and left ventricular mass index (LVMI) in patients with chronic kidney failure undergoing hemodialysis. Understanding this relationship is very important so that appropriate interventions can be done to prevent the development of left ventricular hypertrophy and other heart complications that can occur due to this condition.

The Importance of Understanding the Relationship between Lipid Profiles and LVMI

Understanding the relationship between lipid profiles and LVMI is crucial in the management of patients with chronic kidney failure undergoing hemodialysis. By identifying the factors that contribute to the development of LVH, healthcare providers can develop targeted interventions to prevent or reduce the risk of LVH and its consequences for heart health.

Method

In this study, the latitude cut approach was applied to 55 patients undergoing hemodialysis at Adam Malik Hospital Medan, between February and July 2014. The data collected included history, vital signs, physical examination, and routine blood tests that include ureum, creatinine, lipid profile, and echocardiography to assess LVMI. The relationship between Lipid and LVMI profiles was analyzed using the Pearson correlation test, while the Mann-Whitney test was used to compare LVMI based on categorical parameters.

Study Design and Methods

This study used a cross-sectional design to evaluate the relationship between lipid profiles and LVMI in patients with chronic kidney failure undergoing hemodialysis. The study population consisted of 55 patients undergoing hemodialysis at Adam Malik Hospital Medan, between February and July 2014. The data collected included history, vital signs, physical examination, and routine blood tests that include ureum, creatinine, lipid profile, and echocardiography to assess LVMI.

Results

The study found that there was a significant negative correlation between HDL and LVMI cholesterol with statistical values (R: -0.507, P: 0,0001). This shows that the lower the HDL cholesterol level, the higher the LVMI in patients. In addition, also found a significant positive correlation between systolic blood pressure (R: 0.389, p = 0.003) and diastolic (R: 0.542, p = 0,0001) with LVMI. However, no significant relationship was found between hemoglobin (p = 0.059), total cholesterol (p = 0.600), triglycerides (p = 0.088), and LDL (p = 0.937) against LVMI. In addition, patients who receive ace-inhibitor/ARB show lower LVMI compared to those who do not receive the therapy, with a significant difference (p = 0,0001).

Findings of the Study

The study found a significant negative correlation between HDL and LVMI cholesterol, indicating that lower HDL cholesterol levels are associated with higher LVMI in patients. Additionally, the study found a significant positive correlation between systolic blood pressure and diastolic blood pressure with LVMI, indicating that higher blood pressure is associated with higher LVMI. However, no significant relationship was found between hemoglobin, total cholesterol, triglycerides, and LDL with LVMI.

Conclusion

This study shows a significant negative correlation between HDL and LVMI cholesterol in chronic kidney failure patients undergoing hemodialysis. Conversely, total cholesterol levels, triglycerides, and LDL do not show a significant relationship with LVMI. This finding indicates the need for more attention to lipid profile management, specifically increased HDL levels, as an effort to prevent or reduce the risk of left ventricular hypertrophy and consequences for heart health in hemodialysis patients. With a better understanding of these factors, more effective prevention strategies can be developed to help improve the quality of life of patients with chronic kidney failure.

Implications of the Study

The study highlights the importance of lipid profile management in patients with chronic kidney failure undergoing hemodialysis. The findings of the study indicate that increased HDL levels are associated with lower LVMI, suggesting that lipid profile management should focus on increasing HDL levels. Additionally, the study suggests that blood pressure management is also crucial in preventing or reducing the risk of LVH. With a better understanding of these factors, healthcare providers can develop targeted interventions to improve the quality of life of patients with chronic kidney failure.
