At the time, I was your average healthy, happy middle-aged professional woman who had been a distance runner for 19 years. While recuperating in the coronary intensive care unit afterwards, I asked: \u201c<em>How could this have happened to ME?<\/em>\u201d<\/p>\n<p>What nobody told me then as a freshly diagnosed heart patient was that pregnancy complications many years earlier had increased my subsequent heart disease risk by 2-3 fold. As the Dutch obstetrician Eric Steegers told a Toronto conference audience last fall, reproductive disorders like preeclampsia are \u201c<em>a short term problem for the OB-GYN, but a long term problem for the cardiologist.\u201d (<a href=\"http:\/\/www.pregnancyhypertension.org\/article\/S2210-7789%2812%2900004-9\/references\">Meeke Hoedjes et al 2012<\/a><\/em>).<\/p>\n<p>Yet out of all the cardiac risk calculators I\u2019ve seen (and there are many), I\u2019ve yet to see even one that asks about pregnancy complications.<\/p>\n<p>If the NHS calculator really wanted to figure this out, it would ask about healthy sleep habits. Or what about the endothelium damaging dangers of living with chronic stress? It didn\u2019t even ask me if or when I exercise, or if I follow a heart smart Mediterranean diet (the most widely studied cardioprotective way to eat).<\/p>\n<p>In short, lifestyle based contributors to heart disease risk are nowhere to be found.<\/p>\n<p>As cardiologist Aseem Malholtra told <a href=\"http:\/\/www.telegraph.co.uk\/news\/health\/news\/11457774\/Official-NHS-calculator-predicts-when-you-will-have-a-heart-attack.html\"><em>The Telegraph<\/em><\/a>: \u201c<em>It is a pretty crude evaluation to only use weight as a proxy for lifestyle.<\/em>\u201d<\/p>\n<p>John Deanfield, an NHS cardiologist who helped develop the tool, has called this risk calculator a \u201c<em>wake-up call<\/em>\u201d that could \u201c<em>nudge<\/em>\u201d people to make lifestyle changes to improve heart health.<\/p>\n<p>But let\u2019s examine how well we\u2019re doing so far in convincing even those who are already diagnosed with heart disease to make these important changes.<\/p>\n<p><a href=\"http:\/\/www.ncbi.nlm.nih.gov\/pubmed\/23592106\">In the PURE study<\/a> (Teo et al, <em>JAMA<\/em>, 2013), for example, researchers followed over 7500 heart attack survivors in 17 countries. They found that:<br \/>\n\u2022 <em>48% of smokers continued to smoke.<\/em><br \/>\n<em>\u2022 65% did not exercise.<\/em><br \/>\n<em>\u2022 over 60% did not improve their diet.<\/em><br \/>\n<em>\u2022 14% had adopted not one single lifestyle improvement.<\/em><\/p>\n<p>Again, these were people already living with serious, life threatening cardiac conditions.<\/p>\n<p>Finally, a heart disease risk calculator is only as good as its predictive accuracy. And as health journalist Michael O\u2019Riordan of <em>TheHeart.Org<\/em> astutely asked during the American Heart Association\u2019s scientific meetings in Dallas, while discussing the much ballyhooed US calculator:<\/p>\n<p>\u201c<em>How do you have a serious discussion about the patient\u2019s risk if the risk calculator doesn\u2019t accurately calculate risk?<\/em>\u201d<\/p>\n<p>Here\u2019s what I now tell my women\u2019s heart health presentation audiences: why not live your life assuming that you are ALL at very high risk of having a heart attack? There is simply no downside in starting today with a healthier diet, adding more physical activity, not smoking, getting a good night\u2019s sleep, managing your stress, your weight, or your blood pressure. And not because you don\u2019t want to have a heart attack (that\u2019s what psychologists call an \u201c<em>avoidance goal<\/em>\u201d) but because from now on, you want to feel and look great (an \u201c<em>approach goal<\/em>\u201d).<\/p>\n<p>You don\u2019t need to wait for yet another cardiac risk calculator to tell you to just start.<\/p>\n<p><em><strong>Competing interests:<\/strong> I declare that I have read and understood the BMJ Group policy on declarations of interest and I have no relevant interests to declare\u2014except that I do not use a cardiovascular disease risk calculator anymore.<\/em><\/p>\n<p><em><strong>Carolyn Thomas<\/strong> is a heart attack survivor, women\u2019s health activist, and blogger at <a href=\"http:\/\/www.myheartsisters.org\/\">Heart Sisters<\/a>.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>To see for myself how reliable the new NHS heart disease risk calculator is, I completed all required fields exactly as I would have answered seven years ago.
