Naisten sydänterveys – elinikäinen projekti

More than 3.5 million women in the UK are living with heart disease1. However, it is often perceived as a “man’s disease”. Historically, these misperceptions have meant that women are often overlooked when assessing risk of cardiovascular disease (CVD), and there are many reports of women experiencing delays in diagnosis and subsequently receiving poorer treatment compared to men 2,3. For example, diabetes diagnosis tends to occur at an older age in women, as well as at a greater degree of overweight, and often at a more advanced stage of the disease4. With diabetes having a greater impact on increased risk of incident coronary heart disease (CHD) in women relative to men5,6, earlier diagnosis of diabetes is a top priority as a key strategy in female CVD prevention.

Similarly, although the approach to treating high cholesterol and triglycerides is the same for men and women, research shows that women are less likely to be prescribed cholesterol-lowering drugs compared to men at all ages up to 757. Inequalities in healthcare delivery are demonstrated by poorer survival chances for women who go on to suffer a heart attack8. The statistics are alarming: worldwide, CHD is the single biggest cause of death in both men and women, and in the UK it kills more than twice as many women as breast cancer across all age groups9,10. It is essential that we continue to make heart health a priority for women of all ages11.

Many of the modifiable risk factors for CVD are common to both men and women. These include:
• obesity
• hypertension
• diabetes
• dyslipidaemia

As well as lifestyle-related factors such as:
• poor diet
• lack of physical activity
• smoking
• excess alcohol consumption

However, the weighting of risk can differ between sexes. For example, having a higher systolic blood pressure, being a smoker, and having diabetes are all associated with a greater risk of myocardial infarction for women compared with men12.

Many under-recognised risk factors disproportionately affect women, such as:
• socioeconomic status
• exposure to deprivation
• job-related stress
• psychosocial stress
• depression
• being affected by abuse/violence2

Whilst men tend to develop CVD approximately 10 years earlier than women, menopause brings an acceleration in risk, driven by a sharp increase in LDL cholesterol, central fat deposition, endothelial dysfunction, and blood pressure13. Reduced secretion of oestrogen is thought to be primarily responsible. Oestrogen receptors are widely distributed in the cardiovascular system; oestrogen may protect women by improving vascular function and repair, reducing oxidative stress, improving mitochondrial function and reducing fibrosis. However, dietary habits, work and home-related stress, and reduced physical activity are also implicated in the rapid deterioration in cardiovascular health during this period in women’s lives14.

There are a number of female-specific risk factors that are not included in risk estimate algorithms such as QRISK-3. In fact, a study of more than 120,000 patients found that up to 15% of women under the age of 65 with CHD did not have hypertension, hyperlipidaemia, diabetes, or smoke15. Gestational diabetes, pregnancy-induced hypertension, pre-eclampsia, and pre-term delivery may persist in their effects on the cardiovascular system beyond pregnancy, leading to increased risk of CVD16. Exposure in young adulthood to reproductive endocrine/gynaecological disorders such as polycystic ovary syndrome, endometriosis or premature menopause are associated with risk factors for CVD13. Finally, other aspects of reproductive life history may be relevant for CVD risk in women, such as early age of menarche17 and duration/type of oral contraception18.

As part of the NHS Long Term plan, the 5-yearly NHS Health Check for men and women aged 40-74 is designed to monitor CVD risk factors and offer advice on diet, exercise, smoking and weight management, and may result in pharmacological treatment for hypertension or hyperlipidemia.

The Public Health England Best Practice Guideline for NHS Health Check recommends considering additional risk in women with past gestational diabetes or with polycystic ovary syndrome in addition to the generic risk filter for the assessment of diabetes risk19. Otherwise, this fairly generic approach to CVD prevention is at least partly attributable to the fact that women, especially women from national minority ethnic groups, have been under-represented as participants in clinical trials for CHD and heart failure and as a result, there is a dire lack of evidence to inform the development of female-focused risk estimates11.

Over the past decade there has been a concerted effort to implement change20, but considering large and longitudinal studies are resource-intensive and it can take a long time to reach an evidence-based consensus, a targeted approach may take some time to achieve.

So what can be done to rectify the current inequities in preventative treatment and cardiac rehabilitation experienced by women across the world?
Atherosclerosis begins in childhood21, so approaching CVD prevention as a lifelong undertaking is crucial to any strategy. Behaviour change strategies need to be tailored to pre-, peri- and post-menopausal women as they experience different barriers at various life stages22,23.

Younger women attending routine healthcare appointments should be checked for CVD risk factors and sign-posted to sources of behaviour change support; this is particularly crucial where there are sex-specific risk factors present such as polycystic ovary syndrome, premature menopause or endometriosis. An estimated 10-15% of women experience an adverse pregnancy outcome and consequently have a twofold increased risk of CVD after gestational diabetes 24, pre-eclampsia25 or gestational hypertension26. Regular and sustained monitoring and management of CVD risk factors should be continued beyond pregnancy.

Although there are currently no risk stratification algorithms that incorporate sex-specific risk factors to aid decision making on pharmacotherapy, this is mainly due to lack of data in younger women, whereas older women may have already developed traditional risk factors such as hypertension and type 2 diabetes. Women who seek healthcare advice during peri- and post-menopause should be assessed for CVD risk, including measuring waist circumference (which may be a more important indicator of risk than BMI, especially as oestrogen levels decline), and it is important that their past history of pregnancy and reproductive disorders should be taken into account when deciding on risk management strategies and treatment.

The importance of lifelong healthy eating, being physically active, and maintaining a healthy body weight for reducing preventable cardiovascular deaths cannot be overstated; these three factors along with non-smoking could have prevented ~70% of incident CHD events in women with an average age of 50 after 20 years of follow up27.

When it comes to heart-healthy dietary advice, particular emphasis should be put on:
• consuming a diet rich in wholegrains, fruits and vegetables, nuts and seeds and other plant-based protein sources such as soy, beans and pulses
• using spreads and oils rich in unsaturated fats
• limiting alcohol intake & sugar-sweetened beverages
• limiting salt, red and processed meat, and bakery and dessert products rich in saturated fats and refined starches and sugars28
• Pre-menopausal women should be encouraged to eat 2 portions of fish per week, at least one of which should be oily, as evidence supports the cardioprotective effects of regular fish consumption29
• Girls and women of childbearing age are advised not to consume more than 2 portions of oily fish per week, but postmenopausal women can eat up to 4 portions of oily fish per week.
In addition to these dietary changes, women with raised blood LDL cholesterol, even if taking statins, can significantly lower their blood cholesterol by consuming 2-3 g per day of plant sterols or plant stanols in fortified foods such as spreads30.
Increasingly research is showing how important physical activity is for prevention of CVD in older women. Reducing sedentary time by an hour a day was associated with 26% lower risk of heart disease in women with an average age of 7931, and activities such as gardening or walking should be strongly encouraged32.

Finally, the significant benefit of adequate sleep duration in women mid-life is another opportunity for lifestyle modification in short-sleepers that could reduce CVD risk by 10% 33.
Women have different risk profiles, barriers to diagnosis and treatment, as well as differing pathophysiology of CVD, and many cardiovascular deaths and incidences could be prevented by utilising growing datasets on these female-specific factors to refine clinical guidelines.

Otsikko: Naisten sydänterveys – elinikäinen projekti

Sydän- ja verisuonitauteja on yleisesti pidetty pääasiassa miesten ongelmana, vaikka ne ovat naisten yleisin kuolinsyy maailmassa1. On arvioitu, että naisen todennäköisyys kuolla sydän- ja verisuonitautiin on noin yhdeksänkertainen verrattuna rintasyöpään2-4. Tyypillisesti naiset sairastuvat sydänsairauksiin keskimäärin kymmenen vuotta miehiä vanhempina. Naisten sydäntaudin riskiä helposti aliarvioidaan, jonka vuoksi diagnoosin ja hoidon saaminen saattaa viivästyä. Erään tutkimuksen mukaan lipidilääkityksen aloittaminen naisille oli miehiä epätodennäköisempää kaikissa ikäryhmissä 75 ikävuoteen asti5, vaikka hoitosuositus dyslipidemioiden hoitoon on sama molemmille sukupuolille. Viime aikoina on kuitenkin havahduttu siihen tosiasiaan, että myös naisten sydäntaudin riskiin on syytä kiinnittää huomiota aiempaa aikaisemmin.

Sydän- ja verisuonisairauksien pääasialliset riskitekijät, kuten ylipaino, kohonnut verenpaine, diabetes ja dyslipidemiat ovat samat sukupuolesta riippumatta. Sukupuolten välillä on kuitenkin havaittu eroja yksittäisten riskitekijöiden merkityksessä riskin suuruuteen6. Eräässä hiljattain julkaistussa tutkimuksessa havaittiin tyypin 2 diabeteksen aiheuttavan suuremman sydän- ja verisuonisairauksien riskin naisilla kuin miehillä7. Tyypin 2 diabeteksen varhaisella diagnosoinnilla onkin merkittävä vaikutus naisten sydäntaudin riskin alentamisessa. Myös kohonnut systolinen verenpaine ja tupakointi on yhdistetty suurempaan sydäninfarktin riskiin naisilla kuin miehillä8.

Hedelmällisessä iässä olevien naisten riski sairastua esim. sepelvaltimotautiin on noin viidesosa vastaavan ikäisten miesten riskistä. Vaihdevuosien jälkeen riski kuitenkin lisääntyy selvästi ja on kymmenen vuotta vaihdevuosien alkamisen jälkeen samalla tasolla vastaavan ikäisten miesten riskin kanssa. Estrogeenillä on osoitettu olevan monia sydänterveyttä tukevia vaikutuksia mm. verisuonten seinämän toimintaan9. Nämä edulliset vaikutukset vähenevät estrogeenin erityksen hiipuessa. Hormoniaineenvaihdunnan muutokset vaikuttavat epäedullisesti myös esimerkiksi veren kolesterolipitoisuuteen ja triglyseridiarvoihin. Kohonnut kolesteroli on yksi tärkeimmistä sydän- ja verisuonisairauksien riskitekijöistä.

Viime aikaisissa tutkimuksissa on osoitettu muitakin naisille spesifejä sydänsairauden riskitekijöitä. Esimerkiksi raskauden aikaiset ongelmat, kuten raskausdiabetes, raskauden aikainen korkea verenpaine ja raskausmyrkytys suurentavat sydän- ja verisuonisairauksien riskiä10. Myös muiden lisääntymisterveyden ongelmien, kuten munasarjojen monirakkulaoireyhtymän (PCOS), endometrioosin ja ennenaikaisten vaihdevuosien on esitetty lisäävän sydäntaudin riskiä11. Sydäntaudin riskitekijöiden arviointi ja varhainen hoito tulisikin huomioida myös lisääntymisikäisten naisten terveystarkastuksissa.
Terveellisten elämäntapojen merkitystä sydäntautien ehkäisyssä ei voi liikaa korostaa. Ravitsemussuositusten mukainen, terveellinen ruokavalio, fyysinen aktiivisuus, normaalin painon ylläpitäminen ja tupakoimattomuus ovat ensisijaiset keinot sydänterveyden ylläpitämiselle. Ruokavaliossa tulisi erityisesti kiinnittää huomiota täysjyväviljatuotteiden, kasvisten ja hedelmien, pähkinöiden ja siementen, kasviöljyjen ja ylipäätään kasvipohjaisten tuotteiden osuuteen ruokavaliossa. Lisäksi tulisi pyrkiä syömään kalaa vähintään kaksi kertaa viikossa, eri kalalajeja vaihdellen. Erityisesti rasvaisella kalalla on havaittu olevan sydänterveyttä edistäviä vaikutuksia. Punaisen lihan, tyydyttyneen rasvan, alkoholin, virvoitusjuomien, suolan ja lisätyn sokerin määrää ruokavaliossa tulisi sen sijaan pyrkiä vähentämään. Sydänterveyttä edistävän ruokavalion lisäksi naiset, joilla LDL-kolesteroli on koholla, voivat käyttää kolesterolia alentavia, lisättyä kasvistanolia sisältäviä tuotteita. Suositeltu kasvistanolin päiväannos on 2-3 g. Lisättyä kasvistanolia sisältävät tuotteet soveltuvat käytettäväksi myös statiinihoidon ohessa.
