Palpitations during menopause and the nutrients your heart needs as you age.

It had been a while since we had caught up. Friends since school days, I saw her again when I was visiting the North Island last week. Like many women, the catch-ups over the years became less frequent as ‘life’ got in the way, but when we do see each other, the conversation is easy, as it is when you’ve shared life-long memories.

She knew about my studies on health and ageing and of course, menopause and post-menopause. “You might be interested in this” she said casually. “I’ve been put on beta blockers. I suddenly started to have palpitations. I could feel my heart fluttering so went to get it checked out. I was so worried, so they did all the tests and wore a halter-monitor for a week to see what was going on.” I’m so pleased that she had it all checked out by her Doctor – if this sounds like you, then yes, all palpitations need to be checked by your medical specialist.

I listened to her story, thinking to myself that I had heard the same story from women on my 12 week programmes over the years.  

What did the heart specialist tell you to do about your nutrition, exercise and stress levels now that you’re in post-menopause and your oestrogen is low in post-menopause?” I asked. “Because there are new studies showing the importance of certain nutrients as well as the fact that in post-menopause, adequate protein intake matters too.

I knew from her look, that nutrition, stress management and of course, her intake of Vitamin C which her ageing heart needs weren’t mentioned. She is a regular exerciser and small-framed without any additional fat on her, – she always was, even at school much to my larger-size’ envy. As a small-framed woman in post-menopause, I was wondering if her protein intake was discussed. Maybe, maybe not. However, emerging research from the American College of Cardiology (2020) suggests that protein intake is important for managing atrial fibrillation in women during and after menopause.

Women with the lowest protein intake – roughly equivalent to the current recommended daily amount of protein in the U.S. – had the highest incidence of AFib” said the lead author. “That means that this easily modifiable risk factor for AFib may be a fairly easy way for women to potentially lower their risk.”

The Framingham Heart Study has been going for over 35 years – the duration of most of our lifetime. I’ve taught students about this research for years but as I went into menopause myself and began too experience heart palpitations, this reminded me to go back to it. It confirms that women aged 55 years and older have a risk ratio of 1:3 of developing atrial fibrillation (Vinter, Huang et al, 2020).

Atrial fibrillation is a common arrhythmia (disruption to cardiac rhythm), with increases in the worldwide incidence and prevalence, especially in women entering their post-menopause years.

During the past century, a range of risk factors has been associated with AF, severe complications from the arrhythmia have been identified, and its prevalence has been increasing steadily – especially in post-menopausal women. Whereas evidence has accumulated regarding sex-specific differences in coronary heart disease and stroke, the differences between women and men with AF has received less attention. (Ko, Rahman et al, 2016). 

However, menopausal palpitation distress is common and associated with demographic, clinical, symptom, and quality of life (QOL) factors, states a relatively new report released  by the Journal of Women’s Health (Carpenter, Tisdale et al, 2020). For those of us who have experienced the frightening feeling of a racing heart or missed heart beats (ectopics), especially just after exercise or as I found, when we have just gone to bed, I’m not surprised at what this study shares, 

Compared with the abundance and breadth of research on menopausal vasomotor symptoms [hot flushes] and sleep, there is a relative scarcity of research on menopausal palpitations.  Menopausal palpitations are described as loud, racing, or skipped heart beats, flip-flops, fluttering, or pounding that occurs with or without dizziness and/or light-headedness. Prevalence rates by sample were:

  • 18.6% of 12,425 American women
  • 28.7% of 300 Spanish women
  • 28.8% of 293 American women
  • 34.1% of 299 Moroccan women,
  • 38.0% of 81 Brazilian women
  • 46.8% of 243 Brazilian women, and
  • 46.9% of 301 Lebanese women. 

I wonder what the prevalence is in New Zealand, Australian and British and Irish women? I’m sure the prevlance is similar. The conclusion that the report comes to, is that given that every woman around the world who reaches mid-life will experience menopause, these prevalence rates indicate that millions of women could be experiencing menopausal palpitations. (Carpenter et al., 2020, p. 2).

Oh yes indeed. They could well be. Like my old friend, already in her early 60s.

Does this sound like you? If so, then first and foremost, get to your Doctor for a check-up. Ask for Vitamin D, calcium, magnesium, potassium and of course, B12 and iron levels to be checked as all of these nutrients are affected by menopause – I talk about these a lot in my programmes, because they are important for your cardiac health as you move through menopause. I’ve written about this HERE

The women’s health literature is full of studies reporting the changes in cardiac function as we age. And I’m not talking about when you are over 70 years. I’m talking about your menopause transition – the time when your biological and reproductive ageing is occurring. With the decline in oestrogen levels as we move through menopause, risk factors for coronary heart disease (CHD) become more apparent in women, especially hypertension or high blood pressure.

If your blood pressure has shot up as you approached mid-life, you’ll know what I mean. Furthermore, the onset of hypertension can cause a variety of symptoms that are often attributed to the menopause – if you are experiencing fatigue, hot flushes, aching muscles after exercise, migraines, tinnitus and/or palpitations, then join the club – it could well be your changing blood pressure and blood vessels. So please, go to your Doctor and get your heart and blood pressure checked out when you can, because there’s a little statistic I want to share with you.

Worldwide, 25% of adult women are hypertensive, and in the United States, more than 75% of women older than 60 years of age are hypertensive. [Lima et al., 2012]

That’s why getting the right nutrients into you as you move through menopause matters and it’s why I help women to focus on magnesium, sodium and potassium, especially if they are regular exercisers or you are sweating a lot – you may also be losing vital electrolytes due to sweat losses, although this has rarely been studied (Amabebe, et al. 2016). Whilst too much potassium may be dangerous to the heart, having some in our diet is important – especially for those who exercise. 

Bananas give you potassium as do berries. Berries, bananas and oats are all foods that help you manage your energy levels, exercise recovery and of course, help to regulate your heart and cardiovascular system. Bananas are one of nature’s best sources of potassium with each fruit providing around 300mg. One a day is fine.

Women who eat foods rich in potassium help to lower their blood pressure and as I mention, in my GUT HEALTH module which is part of my Health Restoration Series, then you would also discover the incredible effect that a banana has on the gut microbiome too. Bananas contain pectin, which is a soluble fibre that acts like a sponge in the digestive tract, absorbing fluid and helping to keep our bowel motions in check.

There is such an emphasis on women taking all sorts of supplements to help them with their menopause symptoms, but as I discovered too, real food that gives you the nutrients that your ageing body needs, are cheaper and just as effective.

For post-menoausal women experiencing atrial fibrillation, especially those who are thinner or leaner (or those of you doing higher amounts of exercise) then new research also suggests looking at your protein intake too, (Gerber, 2020) – not too much and not too little, perferably from plants and not too much red meat … exactly what I tell women on my 12 week programmes, especially if they want to turn around their sleep and joint health too.  

The analysis of over 99,000 post-menopausal women (median age of 64 years) from the Women’s Health Initiative Randomized Controlled Trials and Observational Study found that those who ate 58-74 grams of protein a day were 5-8% less likely to develop AFib, but there seemed to be a ceiling effect after eating more than 74 grams, at which point the benefit was no longer statistically significant.

According to the lead author (Gerber, 2020), this doesn’t translate to too much protein. “It’s not a huge amount” he stated. “We’re talking about eating 10-20 more grams of protein per day—that’s only four ounces of healthy protein. Of course, when we talk about increasing protein intake, it needs to be with heart-healthy foods and lean proteins, not with cheeseburgers and other foods that are high in saturated fat, cholesterol and sugar.

Women in this study had an average protein intake of 60 grams/day. This is slightly less than what I recommend on the MyMT™ programmes which supports this study’s findings that women who ate between 58 and 74 grams a day have significantly less risk of AFib. This is a salient point for women who lift weights or do endurance exercise as they move through menopause – you need to examine your protein intake so it is not too high and not too low. I’m always focusing on this aspect of protein intake for cardiac health in the women who join me who are regular exercisers. Protein needs change as we move through menopause and some women are having too much whilst other’s may not be having enough. Interestingly, in the American College of Cardiology report, women typically underestimated their daily protein intake by about 10 grams and caloric intake by 600-700 calories, which speaks to the need for more nutritional awareness and education, researchers said. I agree! 

I talk about protein intake in my 2 hour Masterclass on Menopause too and in the 12 week programmes, I give you specific information relating to your changing cardiac health in mide-life and your nutrition and sleep. That’s what you learn in the MyMT™ programmes where I’ve taken every symptom and placed the strategies into Lifestyle Medicine science. When you’re have time, have a listen to the video below where I explain the 12 week programmes to you.
