Start Checking Your Cholestrol Level from Mid-20s to Avoid Heart Disease: Study

Cholesterol is a fatty substance - a lipid - found in some foods and also produced in our liver

A study has said that people should get their cholesterol levels checked from their mid-20s as the readings can be used to calculate lifetime risks of Heart disease and stroke.

The study, published in “The Lancet”, is the most comprehensive yet to look at the long-term health risks of having too much “bad” cholesterol for decades, the BBC reported.

Researchers maintain that earlier the people take action to reduce cholesterol through diet changes and medication, the better.

Cholesterol is a fatty substance – a lipid – found in some foods and also produced in our liver. It is needed to make hormones like oestrogen and testosterone, Vitamin D and other compounds.

While High-density lipoprotein (HDL) cholesterol is “good” as it keeps the body healthy, Low-density lipoprotein (LDL) is “bad” as it can clog arteries.

Researchers analysed the data obtained from almost four lakh persons in 19 countries and found a strong link between bad-cholesterol levels and risk of cardiovascular disease from early adulthood over the next 40 years or more.

They were able to estimate the probability of a heart attack or stroke for people aged 35 and over, according to their gender, bad-cholesterol level, age and risk factors such as smoking, diabetes, height and weight, and blood pressure.

The BBC quoted the report’s co-author Stefan Blankenberg of the University Heart Center in Hamburg: “The risk scores currently used in the clinic to decide whether a person should have lipid-lowering treatment only assess the risk of cardiovascular disease over 10 years and so may underestimate lifetime risk, particularly in young people.”

Blankenberg told BBC: “I strongly recommend that young people know their cholesterol levels and make an informed decision about the result – and that could include taking a statin.”

However, he added, there is a danger that people could rely on statins rather than leading a health lifestyle and although they were usually well tolerated, studies had not been done on the potential side-effects of taking them over decades.

British Heart Foundation medical director Nilesh Samani said: “This large study again emphasises the importance of cholesterol as a major risk factor for heart attacks and strokes.

“It also shows that for some people, taking measures at a much earlier stage to lower cholesterol, for example by taking statins, may have a substantial benefit in reducing their lifelong risk from these diseases.” (IANS)

Children of Mothers With Diabetes Are Likely To Suffer From Heart Diseases, Says Study

The researchers also found higher rates for specific types of CVD children of mothers with diabetes

Children of mothers with diabetes have increased rates of early onset cardiovascular disease or CVD (conditions affecting the heart or blood vessels) from childhood up to the age of 40, the researchers have warned.

The increased rates were more pronounced among children of mothers with a history of CVD or diabetic complications, said the study published in the journal The BMJ.

“Our study provides evidence that children of mothers with diabetes, especially those with a history of CVD or with diabetic complications, had increased rates of early onset CVD throughout the early decades of life,” said study researchers from Aarhus University in Denmark.

If this association is shown to be causal, preventing, screening, and treating diabetes in women of childbearing age could be important not only for improving the health of the women but also for reducing long term risks of CVD in their offspring, the researchers added

The number of women diagnosed with diabetes before or during pregnancy has increased globally, and children of these women are more likely to have risk factors for future CVD, such as high blood pressure and high blood sugar levels. It is unclear, however, whether or to what extent exposure to diabetes in the womb increases the risk of developing CVD in offspring over a lifetime.

So an international team of researchers set out to evaluate associations between diabetes diagnosed before or during pregnancy and early onset CVD in children during their first four decades of life. They base their findings on national registry data for over 2.4 million children born without congenital heart disease in Denmark from 1977 to 2016.

Diabetes was categorised as pregestational (before pregnancy) or gestational (during pregnancy) and women with diabetic complications were identified.

Other potentially influential factors, such as mother’s age, education, lifestyle and medical history were also taken into account. During up to 40 years of follow-up, children of mothers with diabetes had a 29 per cent increased overall rate of early onset CVD compared with children of mothers who did not have diabetes (cumulative risks: 17.8 per cent vs 13.1 per cent ).

The researchers also found higher rates for specific types of CVD children of mothers with diabetes, particularly heart failure (45 per cent), hypertensive disease (78 per cent), deep vein thrombosis (82 per cent), and pulmonary embolism (91 per cent).

Increased rates were seen in each age group in childhood (before 20 years of age) and early adulthood (from 20 to 40 years of age), regardless of the type of diabetes they were exposed to (pregestational or gestational) and rates were similar for both type 1 and type 2 diabetes, the study said.
