What is "angiogenesis?"
'Angio', from the Greek word 'angeio' meaning blood vessel, and 'genesis' meaning production or birth, together refer to the creation of blood vessels within the body. Angiogenesis is a beneficial natural process occurring during the healing of a tissue injury (like internal or external wounds) or in response to other kinds of tissue offense. It occurs in women during both the monthly reproductive cycle and during pregnancy. Alternatively, angiogenesis can exist as part of a diseased body where it can aid in cases of ischemia or lead to disease in the promotion of tumors. During normal function, the body controls the growth of blood vessels using stimulators called growth-factors.
The Most Unnecessary Cardiac Diagnostic Test
This graphic shows how a cardiac catheter is placed into the body and travels to the heart. This invasive, dangerous surgical procedure is unnecessary.
Noninvasive Diagnostic Test
The doppler uses ultra sound to map the heart and arteries without trauma.
Noninvasive Diagnostic Test
The echocardiogram is not at all traumatic and gives an excellent view of the heart.
Noninvasive Diagnostic Test
The 64-slice CT Scan - data acquisition in cardiac scans implies that the entire heart can be covered in a few heartbeats. This enables an optimal match of the heart rhythm with the data acquisition providing the highest temporal resolution.
