Insights
Administering heparin during coronary angiography did not reduce clot formation or complications. This study found no significant difference in vascular, hemorrhagic, or ischemic events between heparin and placebo groups.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Medicine
Background:
- Coronary angiography involves contrast agent injection into coronary arteries.
- The optimal heparin administration strategy during this procedure remains undetermined.
- This study aimed to evaluate heparin's impact on complications during coronary angiography.
Purpose of the Study:
- To determine the effect of intravenous heparin administration on vascular, hemorrhagic, and ischemic complications during coronary angiography.
- To compare outcomes between patients receiving heparin and those receiving a placebo.
Main Methods:
- A randomized controlled trial involving 500 patients undergoing diagnostic coronary angiography via femoral approach.
- Patients were assigned to receive either intravenous heparin (2000-3000 units) or a placebo.
- Exclusion criteria included severe peripheral vascular disease, aortic stenosis, coagulopathy history, and procedures exceeding 30 minutes.
Main Results:
- Of 482 patients analyzed, heparin administration showed no significant difference in active hemorrhage, groin hematoma, or clot formation compared to placebo.
- Hemorrhagic complications occurred in 2.9% of the heparin group vs. 1.24% of the placebo group.
- Vascular and ischemic complications were also not significantly different between the groups.
Conclusions:
- Heparin administration during coronary angiography did not impact clot formation.
- The study found no significant effect of heparin on hemorrhagic, ischemic, or vascular complications in patients undergoing coronary angiography.
Background:
Coronary angiography consists of the selective injection of contrast agents in coronary arteries. Optimal strategy for heparin administration during coronary angiography has yet to be determined. We assessed the effect of heparin administration during coronary angiography on vascular, hemorrhagic, and ischemic complications.
Methods:
Five hundred candiates for diagnostic coronary angiography (femoral approach) were randomly divided into case (intravenous Heparin [2000-3000 units]) and control (placebo) groups. Assessment included vascular complications like groin hematoma, retroperitoneal hematoma, pseudoaneurysm, active hemorrhage, cerebral ischemia, and clot formation in the catheter or the sheath during angiography. Information was obtained about the patients' age, sex, and hypertension and diabetes mellitus history. Patients with severe peripheral vascular disease, aortic stenosis, history of coagulopathy, and angiography over 30 minutes were excluded.
Results:
Nine patients from each group were excluded. The remaining 482 patients included 285 (59.1%) men and 197 (40.9%) women. In the case group (n=241), 7 (2.9%) patients experienced active hemorrhage at the site of angiographic puncture, 2 (0.83%) developed groin hematoma, and 8 (3.32%) experienced clot formation during angiography, while the corresponding figures for the control group (n=241) were 3 (1.24%), 2 (083%), and 13 (5.39%), respectively. No significant differences were found in hemorrhagic, ischemic, and vascular complications between the two groups.
Conclusion:
Heparin administration during coronary angiography had no effect on clot formation as well as hemorrhagic, ischemic, and vascular complications in our patients.
