Women's heart disease risks and their need to start taking preventive medications should be evaluated when they are in their 30s, rather than well after menopause as is now the practice.
This is according to American researchers who published a study on this, as well as presented their findings at the European Society of Cardiology annual meeting in London, United Kingdom, last week (Aug 30 - Sept 2, 2024).
They said that the study showed for the first time that simple blood tests make it possible to estimate a woman’s risk of cardiovascular (heart) disease over the next three decades.
“This is good for patients first and foremost, but it is also important information for (manufacturers of) cholesterol-lowering drugs, anti-inflammatory drugs, and lipoprotein(a)-lowering drugs – the implications for therapy are broad,” said study leader Dr Paul Ridker of Brigham and Women’s Hospital in Boston, United States.
Current guidelines “suggest to physicians that women should generally not be considered for preventive therapies until their 60s and 70s.
“These new data ... clearly demonstrate that our guidelines need to change,” he said.
“We must move beyond discussions of five- or 10-year risk.”
The 27,939 participants in the long-term Women’s Health Initiative study had blood tests between 1992 and 1995 for low-density lipoprotein cholesterol (LDL or “bad” cholesterol), which are already a part of routine care.
They also had tests for high-sensitivity C-reactive protein (hsCRP) – a marker of blood vessel inflammation – and lipoprotein(a), a genetically-determined type of fat.
Compared to risks in women with the lowest levels of each marker, risks for major cardiovascular events like heart attacks or strokes over the next 30 years were 36% higher in women with the highest levels of LDL cholesterol, 70% higher in women with the highest levels of hsCRP, and 33% higher in those with the highest levels of lipoprotein(a).
Women in whom all three markers were in the highest range were 2.6 times more likely to have a major cardiovascular event and 3.7 times more likely to have a stroke over the next three decades, according to the study paper published in The New England Journal of Medicine.
“The three biomarkers are fully independent of each other and tell us about different biologic issues each individual woman faces,” Dr Ridker said.
“The therapies we might use in response to an elevation in each biomarker are markedly different, and physicians can now specifically target the individual person’s biologic problem.”
While drugs that lower LDL cholesterol and hsCRP are widely available – including statins and certain pills for high blood pressure and heart failure – drugs that reduce lipoprotein(a) levels are still in development by companies.
In some cases, lifestyle changes such as exercising and quitting smoking can be helpful.
Most of the women in the study were white Americans, but the findings would likely “have even greater impact among Black and Hispanic women for whom there is an even higher prevalence of undetected and untreated inflammation,” Dr Ridker said.
“This is a global problem,” he added. “We need universal screening for hsCRP ... and for lipoprotein(a), just as we already have universal screening for cholesterol.” – By Nancy Lapid/Reuters
