Blood Pressure After cabg operation

[OK10]

Hi Guys. I am just wondering if any of you had a simiar problem.

I was taking blood pressure tablets before my operation. I had a cabg4 operation back in September 2024. I was put on blood thinning tablets, blood pressure tablets and thought my blood pressure would go down as a result but it did not.

When I left hospital I was taking 1.25mg ramipril at night and 2.5mg felodipine in the morning. My top reading stayed above 140mmg. We gradually increased ramipril dosage from 1.25 to 2.5 and then to 5mg. Two weeks ago we increased the felodipine dosage from 2.5mg to 5mg. Now the readings are below 140 and 90, which is nice. These dosages are higher that the ones I was taking before my arteries were replaced.

I am also taking 1.25mg bisoprolol.

Why did my blood pressure stayed high after the operation?

Also how can I reduce my blood pressure naturally?

I heard that taking magnessium taurate 125mg twice a day may reduce the blood pressure.

Is anyone taking this type of magnessium please?

Thanks a lot.

a good overview of blood pressure can be obtained from the website of the charity Blood Pressure UK.

They give guidance on diet and lifestyle, and it’s perfectly possible that with tweaks you might be able to reduce your dosage. I’d suggest you don’t take supplements without chatting this through with the pharmacist which your doctor’s group of surgeries (I assume) employs. This subject came up up here a couple of weeks ago, from memory, so if you out the search term into the search box top left of this page, filtering “my communities”, I think you will find what others have said about magnesium.

Thanks for your suggestions

My blood pressure didn't go down after my CABG. I thought it would - new, clear pipes around my heart should, I thought, make blood flow more easily and result in less pressure.

But it didn't and I'm on more medication than I was before the op.

My focus is on healthy eating - as little salt as possible, plenty of greens, no cakes/biscuits, no excessively processed food, very little red meat, that sort of thing - and regular exercise.

I'm not keen on supplements. They may work for some people but interactions between things like magnesium and prescribed drugs are not fully understood. And if they really worked, I think they would be prescribed

Good luck and have a good day!

Blood pressure is generally higher in winter as the cold causes the blood vessels to narrow. Weather generally can make a difference. You can protect against the weather to some extent by say wearing a snood or scarf over your mouth and nose. High winds will also affect you and the high humidity through wetter weather

Are you at the correct weight and have the correct waist measurement? After surgery you may not be doing much exercise. All these will impact on you.

cardiovascular disease is a systemic disease potentially impacting the body’s major blood vessels not just those in the heart. As part of the work up before my CABG I recall having an ultrasound scan of my neck to check the condition of the arteries taking blood to my brain since these too could have been at risk of blockage by fatty deposits and eventually causing a stroke. High blood pressure is a consequence of blood meeting increased resistance as it flows throughout your body and not just the vessels of your heart. This is why CABG, replacing diseased vessels with healthier ones, doesn’t lower blood pressure.

Thanks for that.

Think it very much depends on the hospital you are in as to what medication you are given . I am on bisoprolol. Before my double CABG in 2021 I was on 7.5mg. After the op zi was put on 1.25 but I found that to be a wee bit of a low dose as my heart was racing a bit. My cardiologist recommended 2.5 and since then my heart rate has been nice and steady. Blood pressure normal too. I take the lowest dose perindopril for that.
