Why are heart patients who smoke leaving hospital still smoking?

by Carolyn Thomas @HeartSisters

If you ever needed a swift smack upside the head to convince you to finally stop smoking once and for all, you’d think that a heart attack would do it.

Hospitalized survivors, shocked and traumatized, are already lying there in the cardiac ward unable to light up, and certainly prohibited from smoking anywhere inside the hospital buildings. In some regions, smoking is even banned on hospital grounds, thus requiring a long walk clear across the street, if the patient is even mobile, with the attractive hospital gown flapping in the wind behind. These smokers are already well underway, whether they’d planned it or not, to quitting cold turkey. So why are they starting up again by the time they get home?

Are there any smokers alive out there who are not already aware that smoking is likely what landed them in that cardiac ward in the first place?  Just in case there are, here’s why smoking is so damaging to the heart: 

  • it speeds up progression of atherosclerosis (plaque formation)
  • it alters cholesterol – more LDL (bad) cholesterol and less HDL (good)
  • it increases heart muscle oxygen demand by at least 10%
  • it reduces coronary artery blood flow due to adrenaline release
  • it diminishes blood flow in our smallest coronary collateral blood vessels
  • it interferes with the medicines that heart patients take to prevent angina pain
  • it alters the clotting mechanism of blood platelets
  • it causes endothelial cell dysfunction in the lining of coronary arteries, with reduced ability to produce chemicals that dilate the arteries

Sir Richard Peto, known as the ‘rockstar epidemiologist’ from the University of Oxford, claims that smoking is the absolute biggest risk factor in heart disease. He suggests:

“If you want to kill yourself, start smoking early, and don’t quit.”

Many smokers are getting the message.They are so gobsmacked by suffering a cardiac event that they do indeed quit smoking, often right on the spot. No patches, no gum, no hypnosis, no support groups. But, surprisingly, about half of heart attack survivors who are smokers leave the hospital still hooked, even though researchers show consistently that this decision doubles the chances of suffering a repeat heart attack.  See also: True or False? Most Smokers Need Help to Quit

Scientists at New York’s Feinstein Institute for Medical Research also claim that just weeks after quitting smoking, women show major reductions in several markers of inflammation (C-reactive protein, tumour necrosis factor, among others) that have been clearly associated with heart disease risk. Because smoking is known to promote inflammation, quitting cuts the risk of mortality for both heart and lung disease.

What are we waiting for?  How many more hospital beds and state-of-the-art cardiac procedures and countless hours of clinical expertise will be wasted in treating smokers with repeat heart attacks that are so clearly self-inflicted? Why aren’t all smokers being given mandatory smoking cessation programs while they are still essentially held captive in cardiac wards, thus forced to begin their future as ex-smokers?

The American College of Cardiology confirmed last year that a 10-year study following the progress of smokers who suffered heart attacks showed a remarkable decrease in the likelihood of a second heart attack among those patients who had participated in an intensive stop-smoking education program while still in hospital.

Dr. Patricia Smith of the Northern Ontario School of Medicine reported in the Canadian Medical Association Journal that three factors appear to influence the longterm success in quitting post-heart attack. In addition to receiving the intensive intervention in hospital, successful longterm results were also influenced by:

  • the absence of a previous acute heart attack
  • having a post-secondary education
  • restrictions on smoking at home

I’d interpret that last important factor as blanket permission to lay down the law at home if you have a smoking heart patient anywhere under your roof.  (Cities that have legislated bans on smoking in public places have been remarkably effective in getting smokers to quit just by making it so darned difficult to find a place that tolerates them).

But isn’t a quit-smoking program that starts while a heart patient is still hospitalized just another added financial burden on the health care system?  

Think of the cost as a small investment in health now compared to the big cost of treating future heart attacks later, says an earlier study from Norway.

In other words, we can’t afford not to offer smoking cessation programs in cardiac wards.

Their study found that program costs compare favourably to other standard treatments for heart patients in hospital.  For example, such programs would be approximately 1/25 the cost of offering both statins and ACE inhibitor drugs (both commonly given to cardiac patients).

The Norwegian conclusion: a nurse-led smoking cessation program with several months of intervention is very cost-effective compared with other treatments in patients with coronary heart disease.

  1. It was my 80th birthday on 30/1/20. I had to go to get my fitness for driving test, I got a reminder in January, went to my GP, wasn’t going to but something said just go, you might want to drive.

    My GP found my heart rate was 38, he took blood pressure and did a blood test. I got home from walking my dog, and there was a message to ring the surgery. He said to go straight to hospital.

    I had smoked since I was 16, I always worried about lungs never the heart. I had a tightness in my chest, my thoughts too many ciggies, I had always been very active, but now just couldn’t be bothered.

    Well at the coronary dept, my heartbeat went down to 24. I had a pacemaker put in, all my heart arteries were completely blocked. Yes, what a way to spend a birthday. The ciggies have gone.

    1. First, Happy Belated 80th Birthday to you, Pat! Second, congrats on quitting those cigarettes after SIXTY-FOUR years of smoking! Who knows what might have happened if you had decided not to go see your GP that day? I hope you’re recovering nicely from getting your new pacemaker and will enjoy many more happy smoke-free years!


    2. Hi there I have a question. Before you received the stent, did you ever have black outs for a second but not necessarily faint every time?

      My dad had a stent put in, now he needs a pacemaker and I’m just doing my own research to make sure that’s what he needs . What did it feel like before you got the pacemaker. And how do you feel now?

      And the dr is taking his time with the referral, I found that odd.
      Thank you.


      1. Hello Britt – I’m not a physician so cannot comment specifically on why your Dad has been referred for a pacemaker, although I can tell you that feeling dizzy, light-headed or fainting are common symptoms of a heart rhythm problem that can often be addressed with a pacemaker. I wrote more about pacemakers here.

        You might want to also check out the excellent YouTube channel of Doug Rachac for questions about pacemakers or any other implantable cardiac devices. Doug worked for Medtronic (a huge U.S. company that manufactures these devices) for 14 years until he became a heart patient himself. He now writes and speaks to other patients, and answers commonly asked questions in a no-jargon approachable way. https://www.youtube.com/user/flamtap92

        Your Dad is lucky to have a daughter who is busy going to bat for him. Encourage him to call his doctor for that referral. The squeaky wheel gets the grease, as they say.

        Good luck to you and to your Dad.
        Take care, stay safe…


  2. The people who don’t smoke are so lucky, however I think that they don’t know the power of addiction. It is so simple to advise a smoker to leave smoking. Smoking can only be quit by motivation, not from simple advice.


    1. You’re correct, Irshad. No list of reasons to quit smoking are a surprise to smokers. They already know how dangerous tobacco is, but it’s an addiction that requires an ultimate self-motivated decision to break that addictive cycle. It’s tough, but it can be done.


  3. I had a heart attack on holiday in May 2016. I spent my entire holiday in the hospital after a stent was fitted. I was told by a cardiologist I could continue to smoke! However I would definitely die!!

    I smoked over two packs a day so quite heavy, however I decided that I really would like to stay alive as long as I can, so I have never touched a cigarette since! I’m not going to preach to anyone, but I miss it like hell, no cravings but I just miss it! As if it was my best friend! Even tho it wasn’t really being a friend!!

    But if I had a choice of course I’d light up now, but to me I don’t have that choice, I want to live, and I know I will never light up another cigarette. When I had my stent fitted, I went into another heart attack! Do I really want to kick those doctors in the teeth and be so ungrateful for what they did for me? No I don’t, that’s why I do not smoke anymore!!

    Thanx for your time everyone. I so hope you hear me clearly. Good health to you all.

      2. We ALL are going to die! Stop telling people if they don’t stop they will die. The point is smokers will die sooner, that’s the issue. How much sooner? In the U.S. ads used to be shown telling smokers they would have 10 years taken off their life by smoking. My mother died 10 years sooner I am sure at age 74. She quit smoking for about 2- 4 months because of severe pneumonia requiring surgery. She got out of the hospital and promptly got oral cancer. She had aggressive radiation and it depleted everything in her body. She died in the hospital with pneumonia 2 months later. A oncology nurse told me sometimes stopping smoking allows cancer cells to grow in the mouth. Smoking can keep cancer cells at bay and from multiplying.
