Having an angiogram takes about one hour, although it may be longer, especially if combined with other heart catheter procedures. Preparation and post-procedure care can add more time. After the procedure When the angiogram is over, the catheter is taken out from your arm or groin and the in...

Using a fast version of selective inversion recovery, we have obtained coronary angiograms of normal volunteers showing the proximal portions of the left coronary artery. Blood is tagged in the aortic root at end systole using a 2D inversion pulse. After a wash‐in time of 300–600 ms, the...
Acute coronary syndrome (ACS):Blood flow is sometimes suddenly reduced to your heart. Because that can lead to a heart attack,ACSis treated like an emergency. If you have severe chest pain, seek help right away. Atherosclerotic coronary artery disease:Over time, a sticky, fatty substance called...
Computed tomography (CT) coronary angiogram Sometimes, doctors want a close-up look of your arteries. If so, a special dye is put into your vein before a CT scan. Coronary calcium scan Also called a heart calcium scan or cardiac calcium scan, this test looks for calcium deposits that are...
An immediate coronary angiogram (CAG) may be associated with better outcome after OHCA in neurologically preserved patients but could be futile in other cases. Methods From May 2011 to May 2015, we collected data for all patients admitted in hospital after OHCA in Paris and its suburbs (France...
Invasive coronary angiograms were reported using the 15-segment model. Stenoses with a luminal cross-sectional area were classified as nonobstructive (≥10% and ≤70%) or obstructive (>70%). Prognostically significant CAD was defined as stenosis of the left main stem of more than 50%, obstr...

Angiograms were to be obtained at baseline, after guidewire recanalization, after RT, and after stent deployment, and then forwarded to the Angiographic Core Laboratory (Brigham and Women’s Hospital, Inc., Boston, Massachusetts).
