Frequently Asked Questions (FAQ)


What is Heart Attack?

Heart Attack is the interruption of blood supply to a part of the heart, causing some heart cells to die. This is most commonly due to a blockage of a coronary artery. For more information, read this page.

What is angiography?

Angiography is a medical imaging technique used to visualise the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins and the heart chambers. This is traditionally done by injecting a radio-opaque contrast agent into the blood vessel and imaging using X-ray based techniques such as fluoroscopy.

Is Angiogram and Angiography the same?

Technically "No". Angiography is the method of diagnosis and the film or image of the blood vessels obtained through angiography is called an angiograph, or more commonly, an angiogram. However, these 2 words are used interchangeably by the common people. The difference between the two is the same difference between a "photograph" and "photography".

What is the difference between angiography and angioplasty?

Angiography is an imaging technique used to visualise the interiors of blood vessels, and is a diognosis procedure. Angioplasty, on the other hand, is the technique of mechanically widening a narrowed or obstructed blood vessel. Tightly folded balloons are passed into the narrowed locations and then inflated to a fixed size using water pressures some 75 to 500 times normal blood pressure, and is a treatment procedure.
