CT Angiography in Abbottabad

CT coronary angiography is a scan that photographs the heart arteries from outside the body, using a CT scanner and dye injected into a vein in the arm. Nothing is passed into the heart. It answers one question particularly well: are these arteries clear, or not?

What is CT coronary angiography?

It is a detailed CT scan of the heart, timed to the heartbeat, that shows the coronary arteries and any narrowing inside them. You lie on the scanner table with ECG leads on the chest, a cannula goes into a vein in your arm, and the dye is injected as the scanner runs. The scan itself lasts a few minutes.

The important distinction is between looking and treating. CT angiography looks, and it looks well. Invasive coronary angiography also treats: if a blockage is found, the same catheter can carry a balloon and a stent to open it in the same sitting. So the two tests answer different questions, and choosing between them is the point of the consultation that comes first.

Who is it most useful for?

The scan earns its place with people whose risk sits in the low to moderate range. If you have chest pain that could be cardiac, no known heart disease, and a moderate risk profile, a normal CT angiography is very good at ruling coronary artery disease out. Being told plainly that your arteries are clear is worth a great deal, both clinically and for peace of mind.

It also helps when an exercise tolerance test was inconclusive, or when symptoms and test results disagree and the picture needs settling.

There are people it suits less well. A very fast or irregular heartbeat blurs the images. Heavy calcium in the artery walls, common in long-standing diabetes and in older patients, can scatter the picture and make narrowing hard to grade. Reduced kidney function limits the dye that can safely be given. And in someone already known to have severe disease, the scan mostly confirms what is known while delaying the procedure that would actually treat it.

How do I prepare for the scan?

Expect to fast for around four hours, and to skip tea, coffee, energy drinks and other caffeine on the day of the scan. Caffeine raises the heart rate, and a faster heart makes for blurrier pictures. You may be given a tablet beforehand to slow the heart into the right range.

Bring your medicine list, or the strips themselves. Tell the team about kidney problems, diabetes, asthma, or any previous reaction to contrast dye, because each of those changes how the scan is planned. If you take metformin, ask specifically whether to pause it, and pause it only on a doctor's instruction.

What happens on the day?

You change into a gown, ECG leads go onto the chest, and a cannula is placed in a vein in the arm. On the table you are asked to hold your breath for a few seconds at a time while the scanner runs, because a still chest gives a sharp picture. When the dye goes in you will feel a warm flush spread through the body and often a metallic taste. Both pass within seconds and neither is a cause for concern.

Then it is over. There is no wound, no stitches and no recovery period. You can eat, drive and go back to work the same day. Drinking plenty of water afterwards helps clear the dye.

What do the results mean?

The report describes each major artery and how much narrowing is present, often with a calcium score alongside. A clear scan is strong evidence that the arteries are not the source of the problem, and the search moves elsewhere. Mild narrowing usually means treatment with medicines and attention to blood pressure, cholesterol, sugar and smoking, rather than any procedure.

Significant narrowing is the finding that changes the plan. At that point an invasive angiography is generally the next step, because it both confirms the picture and allows angioplasty with a stent if the artery needs opening.

What matters is that the report is read alongside the person. The same scan means different things in a 40-year-old with no risk factors and a 65-year-old with diabetes. Dr. Muhammad Ali Khan, Consultant Cardiologist, reviews the images and the report with you, explains which arteries are involved and in plain terms, and agrees what happens next.

How do I arrange one?

Start with a consultation rather than the scan. CT angiography is the right test for some people and the wrong one for others, and booking it without an assessment risks paying for pictures that do not answer your question. Bring any previous ECG, echo or treadmill reports with you.

For the exact current price, book an appointment or call the clinic and the team will confirm it before you commit to anything. Book through the appointments page.

One boundary worth stating plainly. This scan is for investigating symptoms in a planned way, not for an emergency. If you have chest pressure, a cold sweat or sudden breathlessness right now, call 1122 or go straight to DHQ Hospital Abbottabad Emergency.
