Population

13 normal healthy adults or patients with open heart surgery (normo-lipidemic subjects)

Comparison

Heparin 3 mg/kg body weight injection vs Baseline (pre-injection)

Design

Other

Implication

Heparin-released LPL may selectively lower VLDL-TG without affecting LDL/HDL in normolipidemics; leaves open clinical or therapeutic relevance.

Structured PICO

Does heparin injection alter plasma lipoprotein levels via lipoprotein lipase release in normo-lipidemic humans?

P
Population
13 normal healthy adults or patients with open heart surgery (normo-lipidemic subjects)
I
Intervention
Heparin 3 mg/kg body weight injection
C
Comparator
Baseline (pre-injection)
O
Outcome
Changes in blood lipid composition (triglyceride, total cholesterol) and levels of lipoproteins (VLDL, LDL, HDL) over 4 hourssurrogate

In normolipidemic humans, heparin-induced release of lipoprotein lipase primarily reduces VLDL triglycerides without significantly affecting cholesterol-rich lipoproteins (LDL and HDL).

Limitations

  • Only normo-lipidemic subjects were studied, limiting generalizability to hyperlipidemic or pathologic conditions
