Hardening of the arteries - CIRCULATORY PROBLEMS.


The arteries of the systemic circulation carrying the "fresh" oxygen-rich blood from the heart to the body. Healthy arteries are elastic and muscular and can adapt to the different blood-pressure situations. Under adverse conditions and with damaged arterial walls are deposited lipids (eg cholesterol) from the inner vascular wall. Later in contact at these points and other substances such as From calcium. The vessel narrows, it is called atherosclerosis or arteriosclerosis. The consequences are circulation problems in the following areas. In addition, such vessels are tightly constrained by a blood clot more easily. Men suffer more often from circulatory problems than women.

The following symptoms may occur depending on the location of the arterial constriction:
* Circulatory problems in the legs lead to the so-called claudicating (it comes to pain, first when walking, and later at rest. There must frequently take breaks when walking) or to the so-called smoker's leg (the tissue on the toes, ankles, legs slowly dying down because it is supplied by the narrowed arteries to oxygen-poor). Under certain circumstances, an amputation may be necessary.
* Narrowing of the coronary arteries leading to angina pectoris or myocardial infarction at a complete blockage of a vessel (heart problems).
* Circulatory disorders in the brain lead to declining brain function, e.g. Memory loss, dizziness, confusion. Depending on which brain region is affected, however, other deficits in other parts of the body, e.g. Numbness in arms or legs, or vision problems are caused. If the vasoconstriction is very strong or if a brain vessel bursts, there will be a stroke.

The following risk factors promote the formation of arterial blockages:
* High blood fat levels (cholesterol and other fats) because fat deposited in the vessels.
*, High blood pressure because this pressure, the vessels more pressures and therefore wear faster.
* Obesity, because this is often associated with high blood pressure or high cholesterol.
* Smoking, because nicotine constricts blood vessels and thereby impairs the blood flow.
* Stress
* Diabetes (sugar disease).
* Age.

What can you do?
* First and foremost, it is important to limit the risk factors (see above).
* For help circulatory problems in the legs: Increase During sleep, the head of about 15 cm, a lot of movement (stairs instead of the elevator!), and Gymnastic exercises.
* For help circulatory problems in the legs: Increase During sleep, the head of about 15 cm, a lot of movement (stairs instead of the elevator!), and Gymnastic exercises.
* The use of ginkgo preparations has a positive effect on blood circulation.
* The use of garlic preparations in sufficient dosage to improve the flow properties of blood and will also reduces the cholesterol.
* Preparations containing omega-3 fatty acids, for example extracted from cold water fish, reduce the risk of deposition in the arteries. They should also improve the flow properties of blood and reduce cholesterol and blood pressure.
* Regular use of aspirin (ASA) in low doses leads to an improvement in blood flow. Talk to your doctor.

When you need a doctor?
* If you experience the above symptoms, or even the suspicion of a circulatory disorder.
* In patients with the above risk factors are important for regular doctor visits.
* If you know that you are suffering from circulatory problems, you should regularly go to the doctor.

What your doctor can do?
* The treatment of the physician is based on the complaints that are caused by narrowing of the arteries. With special investigation methods, the doctor can determine the location and extent of vessel narrowing.
* The doctor may prescribe different to stimulate blood circulation, high blood pressure or blood-thinning medication, as well as remedy for high cholesterol or elevated blood lipids.
* The different types of operations can be restored to affected vessels throughout.
* The operations, vessels can be replaced or "diversions" are established (so-called bypass surgery).

Prevention:
* The best prevention is to avoid or at least the treatment of the above risk factors
* Regular monitoring of blood pressure, cholesterol and blood fat levels.
* If an elevated cholesterol level attention to low-cholesterol diet, i.e., Butter, eggs, meat quantity reduced.
* Diabetics should always ensure that their sugar levels are set correctly.
* Stop smoking or at least reduce.
* Obese should definitely aim for a weight reduction.

Heart disease.


Coronary heart disease (CHD) and angina pectoris.

The heart is through several small arteries - known as coronary arteries or coronary arteries - supplied with blood. In the course of years and decades, can form deposits in these vessels, leading to narrowing. Through these Coronary heart diseases (CHD), the heart will be congested. In the worst case threatens the complete blockage of a coronary vessel and thus the heart attack. CHD and its consequences in industrialized countries are among the most common causes of death. With increasing age deposits in vessels are almost inevitable. There's also a genetic predisposition to CHD. In addition, women with up to the menopause their estrogen production some protection, so that the CAD in them usually occurs later. Besides these non-changing circumstances, there are also factors favoring the occurrence of CHD and can be managed by it, or at least influenced.

Risk factors for coronary heart disease:

* Smoking
* Poor diet
* Lack of exercise
* Obesity
* Stress
* Metabolic disorders, for example elevated cholesterol levels.
* Diabetes
* High blood pressure

Coronary heart disease is insidious because it can progress for a long time without any complaints. Often make the first contractions felt when the heart has an increased oxygen demand, eg during exercise. Then the typical symptom angina pectoris (literally, "chest tightness"). It manifests itself by a strong feeling of pressure or tightness and pain in the chest area. Sometimes this pain also radiate to the left arm, shoulder, neck or in the stomach and are then brought immediately to the heart related. These "attacks" usually last only a few seconds to minutes. Other possible symptoms include dyspnea on exertion or significant arrhythmia of the heart like an extra beat or dropouts. Connect to one or more of these symptoms, you should absolutely see a doctor.

What your doctor can do.

The normal ECG can be completely normal in a coronary heart disease. Much more information provides a stress test. This is often seen that the oxygen supply is no longer the heart during exercise enough. The safest method for the detection of coronary artery disease is cardiac catheterization. Over the bar a small plastic tube (catheter) into the heart is advanced. Then doctors inject contrast medium into the coronary arteries, thus narrowing are clearly visible. Confirmed the diagnosis, various drugs are used to improve blood flow and / or relieve the heart. In addition, possible accompanying diseases such as hypertension, diabetes and lipid disorders are treated. For acute angina pectoris attack, the doctor will prescribe nitroglycerin preparations, e.g. as a spray. They cause an immediate enlargement of the vessels. If the narrowing progressed very far, it is possible to dilate the affected artery mechanically, for example using a balloon. For security a stent (stent) may be used. As the last remaining opportunity for a bypass operation. Here, small replacement vessels - mostly veins from the legs - is removed and sewn as a bridge of the narrowed vessels.

What can you do.

* Give up smoking
* Lose weight
* Do you move enough
* Eat a low fat
* Reduce Stress
* Carry your emergency medication with you at all
* If you are diabetic, watch out for the good attitude of your blood sugar levels
* Do you suffer from high blood pressure, take your medication faithfully

Easy way to beat heart disease

An easy way to beat heart disease,and strokes is quite simple, eat tomatoes!

Tomatoes are a rich source of lycopene
Scientists say a natural supplement made from tomatoes, taken daily, can stave off heart disease and strokes.
The tomato pill contains an active ingredient from the Mediterranean diet - lycopene - that blocks "bad" LDL cholesterol that can clog the arteries.
Ateronon, made by a biotechnology spin-out company of Cambridge University, is being launched as a dietary supplement and will be sold on the high street.
Experts said more trials were needed to see how effective the treatment is.
Preliminary trials involving around 150 people with heart disease indicate that Ateronon can reduce the oxidation of harmful fats in the blood to almost zero within eight weeks, a meeting of the British Cardiovascular Society will be told at Ateronon's launch on Monday.
Our advice to heart disease patients or those at high risk is to rely on proven medications prescribed by their doctor, and aim to get the benefits of a Mediterranean diet by eating plenty of fresh fruit and veg
Professor Peter Weissberg of the British Heart Foundation
Neuroscientist Peter Kirkpatrick, who will lead a further research project at Addenbrooke's Hospital in Cambridge on behalf of Cambridge Theranostics Ltd, said the supplement could be much more effective than statin drugs that are currently used by doctors to treat high cholesterol.
But Professor Peter Weissberg of the British Heart Foundation said: "As always, we caution people to wait for any new drug or modified 'natural' product to be clinically proven to offer benefits before taking it.
"It will take some time, and several clinical trials, to provide such evidence for Ateronon.
"In the meantime, our advice to heart disease patients or those at high risk is to rely on proven medications prescribed by their doctor, and aim to get the benefits of a Mediterranean diet by eating plenty of fresh fruit and veg."
He said the British Heart Foundation had supported some of the basic science at Cambridge University underpinning the development of the product.
Professor Anthony Leeds, trustee of the cholesterol charity Heart UK, said: "The new lycopene product Ateronon represents an entirely new approach to the treatment of high blood cholesterol and opens up the exciting possibility."
He said the preliminary findings were "very promising".
Lycopene is an antioxidant contained in the skin of tomatoes which gives them their red colour. But lycopene ingested in its natural form is poorly absorbed.
Ateronon contains a refined, more readily absorbed version of lycopene that was originally developed by Nestle.
Dr Peter Coleman of The Stroke Association said: "We know that diets rich in antioxidants are beneficial in reducing the plaque build up and welcome the findings of this research."
