New heparin dosing regimen for diabetics undergoing percutaneous coronary intervention.
It has been previously demonstrated that diabetics are less sensitive to heparin compared to non-diabetics. We hypothesized that an initial heparin dose of 80 IU per kilogram administered to diabetics rather than 70 IU per kilogram might yield a more optimal initial ACT of 300 to 350 seconds when glycoprotein IIb/IIIa receptor antagonists are not used. We prospectively studied 130 elective PCI patients without diabetes treated with 70 IU per kilogram of unfractionated heparin and 81 elective PCI patients with diabetes treated with 80 IU per kilogram, and compared the initially achieved ACT. The mean heparin dose given per kg was greater (by intention) in diabetics versus non-diabetics. Despite that, there was no significant difference in the initially achieved ACT in diabetics and non-diabetics.

Hybrid revascularization using percutaneous coronary intervention and robotically assisted minimally invasive direct coronary artery bypass surgery.
Hybrid revascularization (HR) combines staged percutaneous coronary intervention (PCI) on stenoses in the non-left anterior descending (LAD) territories with minimally invasive direct coronary artery bypass (MIDCAB) using the left internal thoracic artery (LITA) to the LAD. The LITA-to-LAD graft, which has a 5-year patency rate of 95%, is the major determinant of the long-term survival for patients. Thus, HR aims to perform full revascularization without compromising the survival advantage of the LITA-to-LAD graft, while preserving the minimally invasive advantages associated with the percutaneous treatment of symptomatic coronary stenoses. We investigated whether HR was a valid alternative to conventional coronary artery bypass graft surgery in patients with multivessel coronary artery disease. We also present our early experiences with HR using a combined approach of advanced PCI and robotically-assisted MIDCAB.
