Heart disease may be inherited, but often it’s the result of lifestyle. Changing eating, exercise and smoking habits can play a significant part in prevention.

The following risk factors can cause heart disease. While there are some you can do little or nothing about, there are others that are worth addressing to make sure you keep a healthy heart:
CLICK & SEE THE PICTURES

Age
Four out of five people who die from coronary heart disease are aged 65 or older.

Gender
Men are more at risk of heart disease than women and have heart attacks earlier in life. However, death rates from heart disease and stroke for women are twice as high as those for all forms of cancer.

The risk for women increases as they approach menopause and continues to rise as they get older, possibly because of the loss of oestrogen, the natural hormone.

Family history
Children of parents with heart disease are more likely to suffer from the disease themselves. Some races, such as Afro-Caribbeans, are more prone to coronary heart disease and stroke than others.

Smoking
Smokers are twice as likely to suffer heart attacks as non-smokers and are more likely to die as a result. Smoking is also linked to increased risk of stroke.

The nicotine and carbon monoxide in tobacco smoke damages the cardiovascular system. Passive smoking may also be a danger.

Women who smoke and take the oral contraceptive pill are at high risk of heart disease and stroke.

Alcohol
Drinking an average of more than one drink a day for women or more than two drinks a day for men increases the risk of heart disease and stroke because of the effect on blood pressure, weight and levels of triglycerides, a type of fat carried in the blood.

Binge drinking is particularly dangerous.

Drug abuse
The use of certain drugs, particularly cocaine and those taken intravenously, has been linked to heart disease and stroke.

Cocaine can cause abnormal heartbeat, which can be fatal, while heroin and opiates can cause lung failure. Injecting drugs can cause an infection of the heart or blood vessels.

Cholesterol
The higher the blood cholesterol level, the higher the risk of coronary heart disease, particularly if it’s combined with any of the other risk factors.

Diet is one cause of high cholesterol; others are age, gender and family history.

Blood pressure
High blood pressure increases the heart’s workload, causing it to enlarge and weaken over time. When combined with obesity, smoking, high cholesterol or diabetes, the risk increases several times.

High blood pressure can be a problem in women who are pregnant or are taking high-dose types of oral contraceptive pill.

Physical inactivity
Failure to exercise is a cause of coronary heart disease as physical activity helps control cholesterol levels, diabetes and, in some cases, can help lower blood pressure.

Obesity
People who are overweight are more likely to develop heart disease and stroke, even if they have none of the other risk factors. Excess weight causes extra strain on the heart, influences blood pressure, cholesterol and levels of other blood fats – including triglycerides – and increases the risk of developing diabetes.

 

Diabetes
The condition seriously increases the risk of developing cardiovascular disease, even if glucose levels are under control. More than 80 per cent of people with diabetes die of some form of heart or blood vessel disease.

Previous medical history
People who have had a previous heart attack or stroke are more likely than others to suffer further events.

Stress
Some links have been made between stress and coronary artery disease. This could be because it encourages people to eat more, start smoking or smoke more than they would otherwise have done.

Garlic ‘Remedy for Hypertension’

[amazon_link asins=’B000NSFQJE,B0078EZQE6,B00E3JUO3M,B002PWYVOC,B001PQMJIY,B01I0V9574,B004JO7BTG,B0055J865W,B001L1KRNC’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’b745e598-6201-11e7-9c83-810849f128d6′]

Garlic may be useful in addition to medication to treat high blood pressure, a study suggests.
…CLICK & SEE
Australian doctors enrolled 50 patients in a trial to see if garlic supplements could help those whose blood pressure was high, despite medication.

Those given four capsules of garlic extract a day had lower blood pressure than those on placebo, they report in scientific journal Maturitas.

The British Heart Foundation said more research was needed.

Garlic has long been though to be good for the heart.

Garlic supplements have previously been shown to lower cholesterol and reduce high blood pressure in those with untreated hypertension.

In the latest study, researchers from the University of Adelaide, Australia, looked at the effects of four capsules a day of a supplement known as aged garlic for 12 weeks.

They found systolic blood pressure was around 10mmHg lower in the group given garlic compared with those given a placebo.

Researcher Karin Ried said: “Garlic supplements have been associated with a blood pressure lowering effect of clinical significance in patients with untreated hypertension.

“Our trial, however, is the first to assess the effect, tolerability and acceptability of aged garlic extract as an additional treatment to existing antihypertensive medication in patients with treated, but uncontrolled, hypertension.”

Experts say garlic supplements should only be used after seeking medical advice, as garlic can thin the blood or interact with some medicines.

Ellen Mason, senior cardiac nurse at the British Heart Foundation, said using garlic for medicinal purposes dates back thousands of years, but it is essential that scientific research proves that garlic can help conditions such as raised blood pressure.

She said: “This study demonstrated a slight blood pressure reduction after using aged garlic supplements but it’s not significant enough or in a large enough group of people to currently recommend it instead of medication.

“It’s a concern that so many people in the UK have poorly controlled blood pressure, with an increased risk of stroke and heart disease as a consequence. So enjoy garlic as part of your diet but don’t stop taking your blood pressure medication.”

Saturated Fat is NOT the Cause of Heart Disease

The saturated fat found mainly in meat and dairy products has been regularly vilified by physicians and the media, but a new analysis of published studies finds no clear link between people’s intake of saturated fat and their risk of developing heart disease.

CLICK & SEE

In the new analysis, which combined the results of 21 previous studies, researchers found no clear evidence that higher saturated fat intakes led to higher risks of heart disease or stroke.

A number of studies have linked the so-called Western diet to greater heart disease risks; that diet pattern is defined as one high in red meats and saturated fats — but it is also high in sweets and other refined carbohydrates like white bread.

Health Spreads Really do Lower Heart Risk

[amazon_link asins=’B0713V9NWJ,B009DGNRCU,B01EUZV5JA,B00FL1CLIC,B00X68XT2E,B00061MT0M,0471593427,B00C8TWVZI,B01LR478MK’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’c574d9a8-5c83-11e7-baaf-13bf9dbd18c1′]

The makers of two leading brands of spreads have been cleared to carry on claiming their products can reduce cholesterol.
Benecol and Flora pro.activ contain plant ingredients which EU health watchdogs now agree can help lower the risk of coronary heart disease….click & see

It is Britain’s biggest killer, with 110,000 victims a year.

Some two in three adults in Britain have raised cholesterol, which leads to clogged arteries and is a factor in heart disease.
The vital ingredients work with the body by partially blocking the entry of cholesterol into the bloodstream. It is claimed they lower bad cholesterol, known as LDL, by up to 15 per cent when used every day as part of a healthy diet and lifestyle.
Currently, millions of people rely on statin pills, prescribed by GPs, to reduce cholesterol. However, these can have side-effects, such as muscle pain.
Dietician and nutrition expert Helen Bond said: ‘People concerned about cholesterol need to have access to reliable, evidence based claims that will help them make wise food choices.

‘Dietary and lifestyle advice is always recommended as the first step for reducing cholesterol. Obesity, diabetes, raised cholesterol and a lack of physical activity are major risk factors for coronary heart disease.

‘This decision by the European Food Safety Authority will help people find the foods that will make a real difference.’
The manufacturers hailed the move to allow their so-called disease risk reduction claims as an important breakthrough.
Benecol products using the cholesterol reducing ingredients, called plant stanol esters, include drinks, yoghurts, spreads and cream cheese.
Benecol spokesman Esther van Onselen said: ‘Approval of the disease risk reduction claim is a really exciting step in helping consumers make an informed choice about which foods are proven to have a positive impact on their health.

‘There are more than 50 independent clinical studies which prove the cholesterol-lowering benefits of plant stanol esters.’
Flora pro.activ is made by Unilever, whose spokesman, Caroline Banquet, said: ‘We are delighted that the EU has now formally granted approval of our disease risk reduction claim.

‘Consumers can continue to be reassured that they can confidently trust our cholesterol-lowering health claims, in the knowledge that the science underpinning them has gone through rigorous and independent expert scrutiny.’
Unilever has carried out research into the cholesterol-lowering properties of plant ingredients since the 1980s. It first introduced Flora pro.activ spread in 2001, followed by yoghurt mini-drinks and milk drinks

Depression is an established risk factor for the development of coronary heart disease (CHD). Dietary factors resulting in lower levels of omega-3 fats not only increase CHD risk, but may also cause depression.
…….
Investigators measured red blood cell levels of two omega-3 fats, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), and assessed depressive symptoms in a cross-sectional study of nearly 1,000 adults with CHD.

As EPA and DHA levels rose, depressive symptoms dropped. The prevalence of depression ranged from 23 percent in participants with the lowest blood levels of omega-3 fats to 13 percent in participants with the highest omega-3 blood levels.
