The risk increases with the exposure time, consisting of 1) time guiding the probe into and out of the heart and 2) time illuminating the contrast agent to perform the angiogram. Absorbed radiation is also a function of body mass index, with obese patients having twice the dose of normal-weight patients; exposure to the operator was also ...
After an angiogram, a sudden shock can cause a little pain at the surgery area, but heart attacks and strokes usually do not occur, as they may in bypass surgery. The risk of complications from angiography can be reduced with a prior CT scan by providing clinicians with more information about number and positioning of the clots in advance.

The most accurate ways to detect CAD are the coronary angiogram and the coronary CT angiography. [4] An angiogram can provide detailed anatomy of coronary circulation and lesions. The significance of each lesion is determined by the diameter loss. A diameter loss of 50% translates to a 75% cross-sectional area loss, considered moderate by most ...

Angioplasty recovery consists of avoiding physical activity for several days after the procedure. Patients are advised to avoid heavy lifting and strenuous activities for a week. [33] [34] Patients will need to avoid physical stress or prolonged sport activities for a maximum of two weeks after a delicate balloon angioplasty. [35]
Treatment is aimed toward preventing future adverse events and relieving symptoms. [12] Beneficial lifestyle modifications include smoking cessation, a heart healthy diet, and regular exercise. [13] Medications such as nitrates and beta-blockers may be useful for reducing the symptoms of coronary ischemia. [6]
