mark: welcome back doctor harvey risch is a expert of epidemiologist from yale, a phd, a doctor, doctort to ask you this question, people with heart disease or asthma, are they likely to die or have a certain type of critical reaction to this drug? >> no. the evidence is that healthy people with heart disease generally do fine on this medication, but like any medication, they should be prescribed with, by a doctor who is following the patient, knows the patient, knows what to expect and is able to monitor it. all medication should be used this way and this is no different but this is a very safe medication. the medication itself has, in some people, perhaps 10% of normal people can change the pacing of the heart muscle contraction car hold the heart rhythm. that change has only measurement value. in other words if you measure it on electro cardiogram you can measure it and hear it. it has almost no bearing for any risk of real arrhythmia that has potentially life-threatening consequences. it is very, very low risk. mark: it's interesting you should say that. on may 1 15 the washington p

joining us now, harvey risch.e is the world-renowned epidemiology professor at the yale school of medicine, and cardiologist and ceo. you've written that the political climate has made objective discussions of hydroxychloroquine impossible. what did she get wrong? >> good evening. she is talking about the h word to, a new expression for that. the problem is, nobody is addressing the science. everybody's talking around the science, talking about the science, but no one's actually talking about the science. that's what i did in my "washington examiner," recently. you have to be very precise. all of the evidence showed it works. it is a miracle drug, it does work, the president was right. he is not the medical expert. the science is the expert, and that is what it says. >> this is supercharged in a horrible way. what is your reaction to this? why -- if you could save lives, why are we worried about cheap political points, no matter what party it is or what drug it is? >> i don't think these are cheap political points

harvey risch, we appreciate your time. thanks for coming on and discussing this. be well. >> thank you. >> "new day" continues right now. >>> good morning everyone. welcome to our viewers in the united states and around the world, this is "new day." alison is off. erica hill joins me this morning. we've been discussing hydroxychloroquine. joining me dr. jean ber rat sew from university of alabama at birmingham and dr. frank la vek i don't, professor at the university of arizona college of medicine. i am not an epidemiologist. dr. risch is. my understanding is based on speaking to many doctors and listening to dr. fauci is these randomized particular sooeb bow controlled trials, there is a reason to we lean on them. >> john, you were smas centerful in that discussion. you clearly have read what we consider to be the gold standard for evidence regarding hydroxychloroquine. indeed, that is the randomized placebo controlled trials. now, sometimes see a gap in what those trials show and what happens in the real world. we call that distinction the perfect effectiveness

harvey risch professor of epidemiologist who wrote a controversial op-ed in support of hydroxychloroquiner being with us. i do appreciate your time. why is it that you think admiral giroir, not to mention dr. fauci and dr. birx are wrong about what they're saying on hydroxychloroquine? >> nice to be with you, john. as of now, there are 12 studies that show that hydroxychloroquine plus zinc and other companion medications when used early in high-risk outpatients convey significant and substantial benefit at reducing the risk of hospitalization and mortality. that's a very precise statement which has very precise conditions for who are the people that need to be treated and how. >> let me just jump in here so people know what you're talking about. when you wrote in the "newsweek" op-ed. none of those are random placebo controlled trials, what dr. fauci refers to as the gold standard. listen to dr. fauci. >> any and all of the randomized placebo controlled trials which is the gold standard of determining if something is effective, none of them had shown any efficacy for hydroxychloroquine. >
