Relationship of serum total cholesterol and triglyceride with risk of mortality in maintenance hemodialysis patients:...

Area of Science:

• Nephrology
• Cardiovascular Medicine
• Clinical Biochemistry

Background:

• The association between serum lipid profiles and mortality in maintenance hemodialysis (MHD) patients is complex and debated.
• Understanding these relationships is crucial for improving patient outcomes.

Purpose of the Study:

• To investigate the independent and combined effects of serum total cholesterol (TC) and triglyceride (TG) levels on all-cause and cardiovascular disease (CVD) mortality in Chinese MHD patients.

Main Methods:

• A multicenter, prospective cohort study involving 1036 MHD patients.
• Baseline serum TC and TG levels were measured.
• All-cause mortality and CVD mortality were tracked during a median follow-up of 4.4 years.

Main Results:

• Higher TC levels (fourth quartile) were associated with a significantly increased risk of all-cause mortality (HR, 1.43).
• Higher TG levels (fourth quartile) were associated with a significantly decreased risk of all-cause mortality (HR, 0.78).
• The lowest risk for both all-cause and CVD mortality was observed in patients with low TC and high TG levels.

Conclusions:

• In Chinese MHD patients, elevated TC is a risk factor for mortality, whereas elevated TG is associated with a reduced mortality risk.
• A combination of low TC and high TG levels predicts the best survival prognosis in this population.
