Q I’ve heard that if I wear an overcoat when I go outside for a smoke, I’ll be okay when I get in and it’ll be no bother to my kids. Is that true?

Kerry Anne, 23

A Sadly this is not the case. The cigarette smoke is unlikely to be contained by your jacket and will end up in your clothes and hair. You also breathe out harmful tobacco smoke for several hours after having a cigarette.

All this leads to increased risk of ear, nose and throat, and chest problems for little children, whose airways are still developing.

It may lead to long term problems especially asthma. My advice would be to look at ways to quit smoking, for your own health as well as that of your children.

Q I got admitted to hospital with a heart attack. Thankfully I am all right but I refused an angiogram because I was scared. Now I don’t know what to do. What do you advise?

Frederick, 74

A I am pleased to hear that you have made a recovery and fully understand that you may have refused an angiogram at a point of stress. However, it is likely that your heart attack was caused by a blocked blood vessel supplying your heart muscle. There isn’t any way to know how severe this is without an angiogram (dye test) and equally if you don’t get this treated, you may be at risk of another heart attack. I would have a discussion with your GP who can refer you back to a heart specialist to review your case.
