Poor diets and smoking cause heart disease

The national average is 0.226% of men, and 0.078% of women.

To combat the number of victims, health chiefs have stressed the importance of changing to healthier lifestyles.

"We need to do a lot more to prevent people developing the disease," said Dr Liam Penny, a consultant cardiologist at the University Hospital of Wales in Cardiff.

"There hasn't been a fall in the number who develop the disease, as there hasn't been a change in lifestyles.

"In Wales, there is a clear link between poverty, poor diet and heavy cigarette smoking."

Biggest killer

Dr Penny stressed this was particularly prevalent amongst manual workers, saying the professional classes are now smoking a lot less.

He also highlighted that women in particular continue to smoke despite repeated health warnings.

"We all have the view it will happen to someone else, and it is a very difficult thing to change one's lifestyle," added Dr Penny.

Coronary heart disease (CHD) is still the single biggest killer in the UK, claiming nearly 125,000 lives a year.

In Scotland, 0.289% of men, and 0.109% of women died, compared to 0.25% of men and 0.089% of women in Northern Ireland.

Advances in treatment have been given as the main reason for the unprecedented drop in CHD.

In Wales, a new �1m strategy to tackle the problem was launched back in the summer.

But the Medical Director at the British Heart Foundation stressed the importance of lifestyle is vital to cut the number of deaths.

"Medical research can do so much to save lives, but in the long run people must take responsibility for their actions," said Sir Charles George.

"Smoking, physical inactivity and a poor diet are the biggest causes of preventable coronary disease."
