Secondhand smoke linked to 30% increased stroke risk

Think just because you do not smoke that you are safe from the thousands of toxic chemicals contained in cigarettes?…Think again. Non-smokers who are regularly in the company of people lighting-up, may still be ingesting all those dangerous fumes and having their health put at jeopardy – through what is known as secondhand (passive) smoking.

It seems a new study emerges every single day that further demonstrates how bad smoking is for the body, and the latest research shows that non-smokers exposed to secondhand smoke can be at a significantly increased risk of suffering a stroke.

The study – published in the American Journal of Preventive Medicine - led by Angela M. Malek, PhD, from the Department of Public Health Sciences, Medical University of South Carolina, Charleston, found that secondhand smoke can raise the risk of developing a stroke by an estimated 30%.

Researchers analysed the national, population-based study ‘Reasons for Geographic and Racial Differences in Stroke’ (REGARDS), a study that assesses cardiovascular disease occurrences and death rates of people aged 45 or over.

Within the REGARDS database, 45% of the people were African-American and 55% were Caucasian. For the purpose of their study, the researchers focused on 22,000 individuals, of which 38% were African-American and 45% were males. Around 23% in total of these people were exposed to secondhand smoke.

Researchers delved into the information deeper to determine if certain types of stroke could be linked to smoking, applying adjustments as well as taking into account factors such as diabetes, hypertension and other cardiovascular diseases.

The findings demonstrate that from April 2003 to March 2012, study participants had reported 428 stroke. Of this total, 352 were ischemic, 50 were hemorrhagic and 26 were due to other subtypes of stroke. Even taking into account the variable factors, there was still a 30% risk of stroke for nonsmokers.

“Our findings suggest the possibility for adverse health outcomes such as stroke among nonsmokers exposed to SHS and add to the body of evidence supporting stricter smoking regulations,” commented Malek.

She added: “In the future, it is necessary for studies to analyse the role of heart diseases in the relationship established in this current research. Possible exposure to other environmental factors such as air pollutants in relation to stroke should also be explored.”

Medical Specialists® Pharmacy offer 6 tips for a healthy heart for National Heart Month

With Valentine’s Day less than two weeks away, the second month of the year often causes pandemonium as couples all around the world, more than at any other time, use all the love in their heart’s to make that extra effort in showing their loved one how much they care.

There could be another reason to think about the heart this month though – for those unaware, February is National Heart Month. The month-long campaign is led by the British Heart Foundation as a way to urge the nation to think more about heart health, as well as to increase awareness about heart and circulatory diseases.

The campaign is one that is annually supported by Medical Specialists® Pharmacy as heart and circulatory diseases are the leading causes of death for adults in Britain. Heart disease comprises of conditions such as coronary heart disease, heart attack and heart failure. However, there are steps to take to help prevent heart problems.

. Cut down on alcohol intake

The NHS recommends that men should not drink more than 3-4 units of alcohol a day, whilst for women the figure stands at just 2-3 units a day at most, and consuming more than this can have a detrimental impact to your heart health. Excessive alcohol intake can raise the amount of triglycerides (a type of fat) in the blood and also lead to abnormal heart rhythms, high blood pressure, heart failure, stroke and obesity from the additional calories you are taking in.  Cutting down on alcohol can be made easier through the help of Medical Specialists® Pharmacy, who have recently began to supply the alcohol dependency treatment Selincro to suitable patients, after being inundated with requests for it.

. Cut down on salt intake

It is recommended that an adult should consume no more than 6g of salt per day – around one full teaspoon. As food labels sometimes only give the figure for sodium, people might be unsure how much they are getting but the following formula from the sodium figure listed, can help: Salt = sodium x 2.5. Therefore, adults should consume no more than 2.4g of sodium per day; equal to 6g of salt. Unfortunately, many of us in the UK consume far more than the 6g limit. On average, people in the UK eat about 8.1g of salt (3.2g sodium) a day. Too much salt can increase the volume of body fluids increases and raise blood pressure. High blood pressure (hypertension) can then result in serious problems such as heart disease or stroke.

.  Cut down on sugar intake

The majority of food and drink products that contain plenty of added sugars, also contain a high number of calories, often having very little nutritional value. Consuming plenty of sugary food and drink on a regular basis can result in weight gain and obesity, thus risking health conditions such as type 2 diabetes and heart disease. Added sugars should comprise of no more than 10% of the energy (calorie intake) obtained from food and drink each day, which works out at around 70g for men and 50g for women, but can vary according to age, size, and how active a person is. Food and drink to consider cutting down on include: sugary cereals, fizzy drinks, sugary squash, cakes, biscuits, chocolate, sweets, cereal bars, cakes, ice cream, puddings and yoghurt.

. Stop smoking

Smoking causes damage to the lining of the arteries, thereby reducing the space for blood to travel through, with the carbon monoxide contained in cigarettes also effecting the amount of oxygen that can reach the heart and other areas of the body, forcing the heart to work much harder to supply the body with the oxygen it requires. The dangers of smoking are further explained on the British Heart Foundation’s website, but smokers are at double the risk of suffering from a heart attack compared to people that have never smoked and smoking is the main cause of a multitude of cancers and lung disease. Smoking cessation treatments such as Champix can help people quit smoking for good though and reduce the risk of heart problems.

. Keep active

Extra weight is widely accepted to be linked to increase the risk of high blood pressure, high cholesterol and type 2 diabetes, and all of these conditions then make heart disease or stroke all the more likely. For those unsure if they are at a healthy weight, body mass index (BMI) is usually one of the first port of calls to check this. A BMI of 25 to 29.9 is considered overweight, whilst a BMI of 30 to 39.9 is considered to be obese. Exercise is a great way to shed the pounds but the simple fact remains that much of the nation lives a sedentary lifestyle. The NHS recommends that one step in treating obesity is to take up activities such as fast walking, jogging, swimming or tennis for 150-300 minutes a week, but obesity treatments like Xenical – in conjunction with a healthy diet – can help with weight loss too.

. Lower cholesterol

Adopting a healthy diet and regular exercise, as previously highlighted, can lower the level of cholesterol in the blood, or prevent cholesterol levels being too high to begin with. The higher the cholesterol level, the higher the risk of stroke or heart disease and therefore the overall risk of having a heart attack. Statin medication such as Atorvastatin or Pravastatin work to lower the LDL (‘bad’) cholesterol and raise the HDL (‘good’) cholesterol, and may be prescribed to certain people with risk factors for heart conditions, such as those with high cholesterol or high blood pressure, older patients, smokers, or those with family history of early heart disease.

The British Heart Foundation’s webpage has more information about heart diseases and advice on how to beat them.  Moreover, the charity are encouraging the nation to show their support on 6 February by wearing red and hosting an event to raise funds for their life-saving research. Anyone can get involved, whether it is at the workplace, school or with friends and family, and there are loads of great ideas for fundraising and essentials such as the sponsorship form and event poster.

Cigarettes more lethal now than they were 50 years ago

Underhand tactics carried out by cigarette companies have resulted in cigarettes being both more deadly and more addictive than they were half a century ago, according to a leading charity.

The Campaign for Tobacco-Free Kids have released an incredible 42-page report titled Designed for Addiction and details how the tobacco companies have purposely engineered cigarettes to produce smoother tobacco smoke that is less harsh and more tempting to those who have never smoked – especially kids.

The charity also add that methods are being utilised to generate and sustain a nicotine addiction for smokers, which will drastically increase their risk of developing lung cancer in the future.

Their research was carried out based on an analysis of scientific studies and tobacco industry documents, in addition to the Surgeon General's report. They found smokers in the present day have a much higher chance of developing chronic obstructive pulmonary disease and lung cancer compared to back in 1964. This is despite smoking less cigarettes.

So how is this so? Well, firstly, nicotine levels have been increased and also sugars are added which is fuelling the addictive effect. The report also alleges that manufacturers add ammonia compounds, which makes it faster for nicotine to get to the brain.

And that isn’t all…Both the taste and smell of cigarettes has been modified by cigarette companies to enable more people to start smoking and continue thereafter, the report states, with levulinic acid utilised to make the smoke feel smoother and less irritating.

The report states: “It is clear that tobacco products – and cigarettes in particular – are highly engineered to expand the appeal of these products and facilitate the consumption of and addiction to nicotine, a highly addictive drug.

“Tobacco companies also know that almost all new smokers begin their addiction as children and that smoking is distasteful for new smokers, so they carefully design the product to appeal to this important market.

“The companies have spent huge sums to research the design of their products and ensure they achieve these goals, even if the impact of these changes also makes the product more dangerous.”
