Abstract

Objectives: Vascular endothelial growth factor (VEGF), a potent angiogenic mediator, can be delivered to targeted tissues by means of a replication-deficient adenovirus (Ad) vector. We hypothesized that direct administration of Ad vector expressing the VEGF121 complementary deoxyribonucleic acid (Ad(GV)VEGFI21.10) into regions of ischemic myocardium would enhance collateral vessel formation and improve regional perfusion and function. Methods: Yorkshire swine underwent thoracotomy and placement of an Ameroid constrictor (Research Instruments and MFG, Corvallis, Ore.) on the circumflex coronary artery. Three weeks later, myocardial perfusion and function were assessed by single photon emission computed tomography imaging (SPECT) with 99mTc-labeled sestamibi and by echocardiography during rest and stress. Ad(GV)VEGF121.10 (n = 7) or the control vector, AdNull (n = 8), was administered directly into the myocardium at 10 sites in the circumflex distribution (108 pfu/site). Four weeks later, these studies were repeated and ex vivo angiography was performed. Results: SPECT imaging 4 weeks after vector administration demonstrated significant reduction in the ischemic area at stress in Ad(GV)VEFG121.10-treated animals compared with AdNull control animals (p = 0.005). Stress echocardiography at the same time demonstrated improved segmental wall thickening in Ad(GV)VEGF121.10 animals compared with AdNull control animals (p = 0.03), with Ad(GV)VEGF121.10 animals showing nearly normalized function in the circumflex distribution. Collateral vessel development assessed by angiography was also significantly greater in Ad(GV)- VEGF121.10 animals than in AdNull control animals (p = 0.04), with almost complete reconstitution of circumflex filling in Ad(GV)VEGF121.10 animals. Conclusions: An Ad vector expressing the VEGF121 cDNA induces collateral vessel development in ischemic myocardium and results in significant improvement in both myocardial perfusion and function. Such a strategy may be useful in patients with ischemic heart disease in whom complete revascularization is not possible.
