The title of this blog comes from the GMC's guide 'Good Medical Practice'. I was reminded of this today when I saw a gentleman on the ward who has a diagnosis of alcohol related cardiomyopathy and has presented with non-sustained ventricular tachycardia. The issue came up as to whether he should be considered for an implantable cardioverter defibrillator. My initial reaction was no but I did ask myself whether his lifestyle choices affected my decision. I think I can safely say not because for me the issue was whether the cardiomyopathy would be reversible if he gave up drinking. It probably is and he is willing to try. in cardiology (as with mose other specialties I guess) lifestyle has a big role to play in illness development. How can we as doctors be sure we don't discriminate?
