Our experience of coronary angiography with and without heparin

Area of Science:

• Cardiology
• Interventional Cardiology

Background:

• Coronary angiography is a common procedure.
• Heparin is typically administered to prevent thrombosis during angiography.
• The necessity and safety of heparin in femoral access coronary angiography require further investigation.

Purpose of the Study:

• To evaluate the safety and efficacy of performing coronary angiography without heparin via the femoral route.
• To assess the impact of omitting heparin on local complications.

Main Methods:

• A retrospective study of 3780 patients undergoing coronary angiography between 2006 and 2010.
• Patients were divided into three groups: standard heparin dose (5000 units), low heparin dose (2000 units), and no heparin.
• Comparison of safety outcomes and complication rates across the three groups.

Main Results:

• The group that did not receive heparin exhibited the lowest incidence of local complications.
• Reduced requirements for blood transfusions and surgical interventions were observed in the no-heparin group.
• No increase in the rate of thrombosis was detected in patients who did not receive heparin.

Conclusions:

• Coronary angiography can be safely executed via the femoral route without the administration of heparin.
• Omitting heparin in this context is associated with a favorable safety profile and reduced complication rates.
