There is an interesting report in the "mind your body" supplement in the Spore Straits Times (http://straitstimes.asia1.com.sg) today about more and more people in Spore opting to undergo a cardiac CT scan.

Spore currently has 16 cardiac CT scanners in public and private hospitals and clinics. All of these are "64-slice" CT scanners, except for the Spore General Hospital which has a Dual-Source CT scanner (equivalent to a "128-slice" scanner).

But heart specialists in Spore say that cardiac CT scans are not for everyone. Those who benefit, according to the Spore National Heart Centre's Dr Terrance Chua, are "people with heart-related symptoms like chest pain or shortness of breath and who have got abnormal or unclear results from a stress test."

Dr Michael Lim of the Spore Heart, Stroke and Cancer Centre, said that several studies have shown that "CT coronary angiogram is highly accurate compared with invasive angiography". He said that normal ECGs and treadmill stress tests are not very useful for preventing heart attacks. "Published studies show that two-thirds of heart attacks occur in patients with 40-60% narrowing of arteries. Yet this is not picked up on treadmill tests or ECG," he said.

Bear in mind that there are risks involved in cardiac CT scans. According to Assoc Prof Tan Huay Cheem of the NUH's cardiac department, these risks include

- the patient having an allergic reaction to the contrast dye injected into him/her
- the contrast dye can also compromise kidney function for people with kidney problems
- the exposure to radiation "equivalent to 600 chest X-rays".

In Spore, a cardiac CT scan costs S$781 at a public hospital and upwards of S$1,000 at private hospitals or clinics.

I had one Ct scan at 2nd Fl hong leong bldg, jalan kia peng. It cost me 1700-00 . instead of 25-35 k if I go for invasive angiogram and angioplast. The trouble is that when the specialist diagnosed an angiogram and ultimately a angioplast, who are we to know it is necessary ? For me I would rather go for the CT scan 64 slice,.
