A long-term effect of which of the following procedures post acute MI induces angioneogenesis?

A long-term effect of which of the following procedures post acute MI induces angioneogenesis?
a) Transmyocardial laser revascularization
TNR procedures usually involves making 20 to 40 channels in ventricular muscle. It is thought that some blood flows into the channels, decreasing the ischemia directly. Within the next few days to months, the channels close as a result of the body’s inflammatory process of healing a wound and new blood vessels form as a result of the inflammatory process.
b) Bracytherapy
Brachytherapy involves the delivery of gamma or beta radiation by placing a radioisotope close to the lesion and has been shown to be effective in reducing the recurrence of obstruction, preventing vessell restenosis by inhibiting smooth muscle cell proliferation.
c) Atherectomy
Atherectomy is an invasive interventional procedure that involves the removal of the atheroma, or plaque, from a coronary artery.
d) Stent placement
A stent is a woven stainless steel mesh that provides structural support to a vessel at risk of acute closure. Eventually, endothelium covers the stent and it is incorporated into the vessel wall. Because of the risk of thrombus formation in the stent, the patient receives antiplatelet medications (e.g., clopidigrel [Plavix]) therapy for 2 weeks and lifetime use of aspirin).
