Atorvastatin is a more powerful drug, weight for weight, with a wide dose range. <a href=\"http:\/\/www.annals.org\/cgi\/content\/abstract\/147\/1\/1\">This study<\/a> compared a dose of 10mg with a dose of 80mg in patients aged 65 or over with stable ischaemic heart disease.<!--more--> There was an absolute difference in cardiovascular events of 2.3% between the groups, which the authors purvey as a strong argument for the high dose. But there was little attempt to quantify adverse events (except biochemically) or cost. A Polypiller would argue that you can get nearly all the benefit for an eighth of the dose.<\/p>\n<p>Whereas statins remain in high favour for protecting the heart, beta-blockers are often relegated to the status of yesterday\u2019s drugs. Not so, according to <a href=\"http:\/\/www.annals.org\/cgi\/content\/abstract\/147\/1\/10\">this pooled analysis of 4 trials<\/a> using intravascular ultrasonography of the coronary arteries, demonstrating that patients on beta-blockers show no increase in atheroma, whereas the rest show progression. All fine, dandy and very hi-tech, but beta-blockers are a very heterogeneous group of drugs, and have effects on much more that atheroma. Which one should I use to prevent real events, and at what dose?<\/p>\n<p>The gold standard for measuring renal function is the real glomerular filtration rate, measured in <a href=\"http:\/\/www.annals.org\/cgi\/content\/abstract\/147\/1\/19\">this study<\/a> by a radiolabelling method (iothalamate). But this study of people with chronic renal failure discovered that a better predictor for progression to end-stage failure or death was a simple serum marker \u2013 cystatin C. So in both renal failure and heart failure, we have the odd situation that a simple blood test predicts outcomes better than the supposed \u201cgold standard\u201d for direct  measurement of function (I am referring to BNP and echographic ejection fraction, in case you hadn\u2019t guessed).<br \/>\nIt might be possible to help some people lose weight by the right kind of counselling, but I don\u2019t seem to manage it. More intensive regimes can bring modest improvements for a period of time, according to <a href=\"http:\/\/www.annals.org\/cgi\/content\/abstract\/147\/1\/41\">this meta-analysis<\/a> of counselling interventions.<br \/>\n<a href=\"http:\/\/www.annals.org\/cgi\/content\/abstract\/147\/1\/51\"><br \/>\nAdvance directives<\/a> are one means by which individuals can try to exert some control over the process of their own dying \u2013 but do they work? This discussion piece from the Ecumenical Center for Religion and Health at the University of Texas points out all the potential inadequacies of advance directives in the actual messy business of modern dying. The argument is ostensibly based on Camus\u2019 \u201cexistentialism\u201d as illustrated in his novel, The Plague. The author concludes that it is our duty to \u201cbear witness to the patients\u2019 suffering\u201d. Oh no it isn\u2019t. It is to relieve the patient\u2019s suffering. That was what Dr. Rieu in the novel risks his life doing for weeks in the plague-ridden, stifling hospital. He couldn\u2019t do much: but if we can help achieve a death in accordance with a dying patient\u2019s stated wishes, shouldn\u2019t we be allowed to do so?<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The current fashion in Britain is to put every patient who is thought to need a statin on 40mg of simvastatin.
