Noninvasive tests (as stress test, nuclear imaging, dobutamine stress echocardiography) help estimate which patients might benefit from undergoing coronary angiography. Many factors are taken into account but generally, people whose tests reviled that portions of cardiac wall receive less blood that normally should proceed with coronary angiography. There, lesions are identified and a decision is taken whether patient should undergo PCI or GABG.Generally,  CABG is preferred over PCI  when there is significant atheromatic burden on the coronaries, that is extensive and complex. According to current literature, decreased LV function, LM disease, complex triple system disease (including LAD, Cx and RCA) especially when the lesion at LAD is at its proximal part and diabetes, are  factors that point patients will benefit more from CABG rather than PCI. Acute coronary syndrome
During an acute heart event, named acute coronary syndrome, it is of vital importance to restore blood flow to the myocardium as fast as possible. Typically, patients arrive at hospital with chest pain. Initially they are treated with medical drugs, particularly the strongest drugs that prevent clots within vessels (dual antiplatelet therapy: aspirin and a P2Y12 inhibitor-like clopidogrel). Patients at risk of ongoing ischemia, undergo PCI and restore blood flow and thus oxygen delivery to the struggling myocardium. In cases where PCI failed to restore blood flow because of anatomic considerations or other technical problems, urgent CABG is indicated to save myocardium.
Angiomatosis is a non-neoplastic condition characterised by nests of proliferating capillaries arranged in a lobular pattern, displacing adjacent muscle and fat. It consists of many angiomas.These tend to be cavernous hemangiomas, which are sharply defined, sponge-like tumors composed of large, dilated, cavernous vascular spaces. Presentation
Associated
They often appear in:

Von Hippel–Lindau disease: It can be associated with Von Hippel–Lindau disease and is a rare genetic multi-system disorder characterized by the abnormal growth of tumours in the body. Symptoms may include headaches, problems with balance and walking, dizziness, weakness of the limbs, vision problems and high blood pressure. Bacillary angiomatosis
Klippel–Trénaunay syndrome
Sturge–Weber syndrome

Histology
It is a vascular malformation wherein blood vessels proliferate along with accompanying mature fat and fibrous tissue, lymphatics and sometimes nerves. They may involve skin, subcutaneous tissue, skeletal muscle and occasionally bone. Prognosis
Prognosis depends on the size and location of the tumour, untreated angiomatosis may lead to blindness and/ or permanent brain damage. Death may occur, with complications in the kidney or brain. See also
