The primary symptom of this is pain, poor organ function and bad general condition. The further consequences are tissue damage, sometimes acute damage because by stop of blood flow caused by a sudden blood clot formed in the narrowed areas.

THE MECHANISMS AND CAUSES OF ATHEROSCLEROSIS

The inner walls of the arteries consist of an innermost layer of endothelial cells (surface cells) and under these a layer of smooth muscle cells. The changes by atherosclerosis take place under the endothelial cells and in this muscle layer. The changes consist of: A certain degree of cell proliferation or tumour, gathering of cholesterol and fat. Deposition of calcium salts and blood elements like fibrin.

The deposits are called atherosclerotic plaque or atheroma. Atherosclerosis is one of several types of artery thickening and hardening. A common name for thickening and hardening of arteries is “arteriosclerosis”. Often atherosclerosis is also just called arteriosclerosis.

The development of atherosclerosis probably begins by a damage in the endothelium. This damage causes cholesterol and fat to penetrate into the vessel walls and deposit there. This also induces cells to proliferate. Later also calcium salts are deposited.

Factors that cause endothelial damage and thus atherosclerosis are:
-High content of cholesterol in the blood.
-High content of blood fat and especially saturated fat.
-Inflammation in the blood vessels. A sign of such inflammation is the presence of a substance called c-reactive protein.
-High amount of oxidation agents in the blood.
-High blood pressure.
-High content of low density lipoprotein (LDL) in the blood serum, and low content of high density lipoprotein (HDL) in the blood. Lipoprotein is a combination of a protein molecule and fat or cholesterol. Lipoproteins carry cholesterol or fat from place to place.
-Diabetes.
-High age.
-Smoking.
-Men have a somewhat higher chance of getting this condition than women.
-High content of the amino acid homocystein in the blood serum.

Many of these factors are ultimately caused by a bad diet and lack of daily exercise.

THE SYMPTOMS AND CONSEQUENCES OF ATHEROSCLEROSIS

Since atherosclerosis can affect all body parts, the symptoms will vary. However, general symptoms from the affected body parts are:
-Decreased performance, easy to tire out.
-Pain by physical activity, so called anoxic pain.
-By severe impairment of blood flow, tissue damage or sores can occur.

When the heart is affected, the symptoms will be:
-General bad condition.
-Anoxic pain from the heart and surroundings by physical activity, called angina pectoris.
-Feeling of not getting enough air, or breathing problems.

Atherosclerosis can cause blood clots that close the blood flow. There are several ways this can occur:

-The atherosclerotic plaque can rupture, making a sore in the inner wall of the vessel. At such a sore blood can coagulate, making a blood clot.
-The atherosclerotic plaque itself can grow to close a blood vessel.
-Blood coagulated at an affected area can tear loose, float with the blood stream to another place and prop a blood vessel at the new place.
-A portion of the plaque itself can tear itself loose and clog another blood vessel.

When the heart is stricken by a blood clot, heart tissue is suddenly destroyed, a condition called heart infarction, causing sudden heart failure or death.

When a blood clot strikes the brain, brain tissue is destroyed or impaired, causing paralysis, decreased consciousness, coma or other sudden functional impairments.

THE PREVENTION AND TREATMENT OF ATHEROSCLEROSIS

Atherosclerosis can be prevented and to some extend be cured by these measures, of which most are lifestyle adjustments:

-Eating just a little or moderate amount of fat.
-Eating just a moderate amount of sugar.
-The fat eaten should be a blending of different types of unsaturated fat from sources like: Olive oil, rape oil, sunflower oil, soy oil, walnut oil and fish. Then you will get enough of mono-unsaturated fat, omega-3-unsaturated fat, and omega-6-poly-unsaturated fat, but not too much of any of them.
-Eating much fish and just a little red meat.
-Eating a good amount of fruit and vegetables each day.
-Supply of enough vitamins, minerals and anti-oxidants.
-Only consuming moderate amount of salt.
-Stop smoking.
-Getting high blood pressure treated if lifestyle measures do not bring blood pressure down.
-Daily exercise fitted for one’s own condition.
-Eliminate stress in the daily life and at the job.
-Stressing down and getting enough rest.

By high cholesterol levels that do not react properly to lifestyle measures, cholesterol lowering medication can be used, such as HMG-CoA reductase inhibitors.

By serious local narrowing of an artery, surgery to clean out or widen the artery is sometimes performed. Sometimes the artery is replaced by a graft taken from another body part or by an artificial vessel. When this is done in the heart, it is denoted as bypass surgery.

Alternative treatment to clean out the arteries is an option. There is for example a treatment consisting of using the substance EDTA to carry constituents of plaque away from the arteries. The molecules of this substance have the ability to grip around other molecules, for example cholesterol molecules, and carry them away. There is however a controversy about the effectiveness of this treatment, called chelating therapy.

Of course, prevention is always better than cure, so before we look at some of the symptoms of cardiac disease we’ll look at some of the ways you can help your body ward off the risks.

Living a healthy lifestyle can go a long way to reducing the chances of developing cardiac problems, but there is unfortunately an element of inherited risk, so even those with excellent overall health may find that they’re genetically programmed towards heart disease in later life. Thankfully, the greatest influence genetics has on heart disease is that of making us more susceptible to certain causes, and with careful adjustments of our lifestyles we can greatly improve our prospects of avoiding it.

The two most deadly contributors to cardiac problems are smoking and obesity. Both of these can raise blood pressure to dangerous levels, putting extra strain on the heart. Smoking causes the build up of fatty deposits within the arteries, also causing circulation problems. Being overweight also tends to mean that a healthy diet is not being followed, and so the body may well be short of essential minerals and nutriments that the heart needs to keep on functioning healthily.

Stopping smoking and other unhealthy practices such as excessive drinking, along with improving diet and taking up exercise to reduce weight can go a long way towards averting problems.

The symptoms of a developing heart problem can be both subtle and dramatic. Unfortunately, many of the symptoms can also signify other less dangerous conditions, and so a diagnosis of heart disease is often made later than it could have been. If you come across more than one of the symptoms below, then a trip to your doctor is highly advisable.

Breathlessness when engaged in physical exercise is normal to some extent for almost everyone, but if you find you’re becoming breathless more and more easily then this is a clear sign that your general fitness levels aren’t all they could be, and that your heart may be struggling under the pressure.

Palpitations, that is a heavily or unevenly beating heart, can be a sign of anxiety or can come on after extreme exercise, but if neither of these situations apply then heart problems could well be the culprit.

A tingling feeling in bodily extremities such as fingers, toes or lips is often a sign that your cirulation system isn’t delivering enough oxygen, again a sign of possible heart problems. Should your extremeities go on to develop a blueish colour then this is certainly not a good sign, and medical attention should be sought at once.

The final and most obvious sign of cardiac problems is a feeling of tightness or pain in the chest, a condition known as angina. If you feel chest pain with any regularity, even if not particularly severely, a medical check up is advisable to make sure you catch any problems as early as possible. Angina can be controlled very well by medication in many cases, and doesn’t necessarily have to develop into full-blown heart disease.

In summary, living a healthy lifestyle while keeping an eye out for the symptoms will greatly reduce the risk of your life being devastated by heart disease.

Patients may not need to fast before having their cholesterol tested, a major report has found.

After analysing data from 300,000 people, Cambridge researchers found results were just as accurate if the patient had eaten before the test.

For decades patients have been told to fast for 12 hours prior to a test.

It is hoped the study, published in the Journal of the American Medical Association, may inform new guidelines for doctors in the UK.

Cholesterol tests have long been a key part of assessing a patient’s risk of cardiovascular problems, and those who turned up having eaten breakfast were required to make a fresh appointment.

It had been thought that the body needed enough time to digest food in the system and to clear any fatty particles from the blood in order to produce an accurate reading of so-called “bad” cholesterol – or low-density lipoprotein (LDL).

Financial pressure

But data from 68 long-term surveys in 21 countries suggests this is not the case.

“For decades, people have been asked to fast overnight before their cholesterol tests,” lead researcher Professor John Danesh said.

“These findings indicate that cholesterol measurements are at least as good – and probably somewhat better – when made without fasting.”

The study also adds to the ongoing controversy over whether testing for blood proteins called apolipoproteins is a more reliable way of predicting heart risk than cholesterol testing.

The studies showed that analysing “good” cholesterol – or high-density lipoprotein (HDL) in conjunction with LDL was just as informative as testing for apolipoproteins AI and B.

Professor Peter Weissberg, medical director of the British Heart Foundation, said: “Given the financial pressure the NHS is under, it’s good news that doctors don’t need to spend money on setting up more sophisticated tests based on apolipoproteins.

“But the study underlines the importance of all GPs being able to measure HDL cholesterol as well as total cholesterol, in order to make the best predictions about heart disease risk.”

Not all doctors currently use tests which differentiate between the two different forms of cholesterol.

Societies involved with heart care are currently drawing up new guidelines for health professionals in the UK, where cardiovascular disease – CVD – is the leading form of death.

When suffering from high blood pressure it is very important to monitor how the values of your blood pressure change during the day. This way you will have an active role in taking care of your own health and it will be very easy to determine what kind of treatment you need.

The price of a digital blood pressure monitor is not too elevated and they are quite easy to use too. When you’ve just bought one the best thing to do is to pay a visit to your doctor and he should be able to instruct you on how to use the blood pressure monitor. It is important to do this because otherwise you may perform innaccurate measurements and this should be avoided.

You must also take into account the fact the values of the blood pressure vary at everyone, so do not be frightened if a few of your readings are a bit over the line, this is normal for everybody. You should only worry if these high values keep repeating, and in this case you should contact your doctor as soon as possible.
Also, the values of the readings that you make with the blood pressure monitors may be lower than usual a few times, which is also normal.
If you want the readings to be as accurate as possible try to sit down, rested, on a hard surface when performing the measurements.

Finally do not forget that the purpose of measuring your blood pressure at home is is to reduce it!

Cardiovascular disease poses a major health threat to both men and women in the U.S. According to the American Heart Association, more than 71 million adults in the U.S. have at least one type of cardiovascular disease. These include dysfunctional conditions of the heart, arteries and veins that supply oxygen to life-sustaining areas of the body such as the brain, the heart itself and other vital organs.

These conditions can be caused by a buildup of fatty deposits in the arteries, elevated cholesterol, high blood pressure and poor circulation. Patients with cardiovascular disease are at increased risk for heart attacks, strokes and death.

A healthy diet and regular exercise are important steps in the prevention of cardiovascular disease. In addition, low dose aspirin can be regarded as a heart health product has  shown to reduce the chances of heart attack and stroke, and help manage other cardio risk factors.

Some of the drugs listed below can affect certain functions of the body, resulting in bad side effects. However, drugs that lower blood pressure have proven effective over the years. The benefits of using them far outweigh the risk of side effects. Most people who’ve taken these drugs haven’t had any problems.

Diuretics — Some of these drugs may decrease your body’s supply of a mineral called potassium. Symptoms such as weakness, leg cramps or being tired may result. Eating foods containing potassium may help prevent significant potassium loss. You can prevent potassium loss by taking a liquid or tablet that has potassium along with the diuretic, if your doctor recommends it. Diuretics such as amiloride (Midamar), spironolactone (Aldactone) or triamterene (Dyrenium) are called “potassium sparing” agents. They don’t cause the body to lose potassium. They might be prescribed alone but are usually used with another diuretic. Some of these combinations are Aldactazide, Dyazide, Maxzide or Moduretic.

Some people suffer from attacks of gout after prolonged treatment with diuretics. This side effect isn’t common and can be managed by other treatment. This is because of hyperurecemia caused by diuretics.

In people with diabetes, diuretic drugs may increase the blood sugar level. A change in drug, diet, insulin or oral antidiabetic dosage corrects this in most cases. Your doctor can change your treatment. Most of the time the degree of increase in blood sugar isn’t much. Impotence may also occur in a small percentage of people.

Beta-blockers — Acebutolol (Sectral), atenolol (Tenormin), metoprolol (Lopressor, Mepressor, Merol), nadolol (Corgard), pindolol (Visken), propranolol (Inderal) or timolol (Blocadren) may cause insomnia, cold hands and feet, tiredness or depression, a slow heartbeat or symptoms of asthma. Impotence may occur. If you have diabetes and you’re taking insulin, have your responses to therapy monitored closely.

ACE inhibitors — These drugs, such as captopril (Capoten), enalapril (Vasotec), lisinopril (Zestril or Prinivil), may cause a skin rash; loss of taste; a chronic dry, hacking cough most common side effect; and in rare instances, kidney damage.

Angiotensin II receptor blockers — These drugs may cause occasional dizziness.

Calcium channel blockers — Diltiazem (Cardizem), nicardipine (Cardene), Nifedipine (Procardia) and verapamil (Calan or Isoptin) may cause palpitations, swollen ankles edema, constipation, headache or dizziness. Side effects with each of these drugs differ a great deal.

Alpha blockers — These drugs may cause fast heart rate, dizziness or a drop in blood pressure when you stand up i.e postural hypoteson

Combined alpha and beta blockers — People taking these drugs may experience a drop in blood pressure when they stand up.

Central agonists — Alpha methyldopa (Aldomet) may produce a greater drop in blood pressure when you’re in an upright position (standing or walking) and may make you feel weak or faint if the pressure has been lowered too far. This drug may also cause drowsiness or sluggishness, dryness of the mouth, fever or anemia. Male patients may experience impotence. If this side effect persists, your doctor may have to change the drug dosage or use another medication.

Clonidine (Catapres), guanabenz (Wytensin) or guanfacine (Tenex) may produce severe dryness of the mouth, constipation or drowsiness. If you’re taking any of these drugs, don’t stop suddenly, because your blood pressure may rise quickly to dangerously high levels.

Peripheral adrenergic inhibitors — Reserpine may cause a stuffy nose, diarrhea or heartburn. These effects aren’t severe and no treatment is required other than to change the amount of drugs taken. If you have nightmares or insomnia or get depressed, tell your doctor. You should stop using the drugs.

Guanadrel (Hylorel) or guanethidine (Ismelin) may cause some diarrhea, which may persist in some people. This side effect usually becomes less of a problem if you continue treatment.

These drugs reduce blood pressure more when you stand. Consequently, you may get dizzy and lightheaded and feel weak when you get out of bed in the morning or stand up suddenly. If you notice any of these reactions — and if they persist for more than a minute or two —  sit or lie down and either reduce or omit the next dose of the drug. If symptoms continue, contact your doctor.

When you’re taking guanethidine, don’t keep standing in the hot sun or at a social gathering if you begin to feel faint or weak. These activities cause low blood pressure. Male patients may experience impotence. Contact your doctor if this occurs. These drugs are rarely used unless other medications don’t help.

Blood vessel dilators — Hydralzine (Apresoline) may cause headaches, swelling around the eyes, heart palpitations or aches and pains in the joints. Usually none of these symptoms are severe, and most will go away after a few weeks of treatment. Minoxidil (Loniten) is a potent drug that’s usually used only in resistant cases of severe high blood pressure. It may cause fluid retention (marked weight gain) or excessive hair growth.

Heart Attack

Very often, it is quite difficult to differentiate between a heart attack and heartburn. The common signs of a heart attack are a tightness, pain, or discomfort in the chest. Sweating, nausea, and vomiting that are accompanied by intense pressure in the chest. A radiating and intense pain in the chest that extends from the chest to the left arm. A shortness of breath for more than a few minutes.  If you have any of the above you must consult the doctor or go to the emergency rooms.

If you even think you are having a heart attack you must call for a cardiac care ambulance, and put under your tongue a nitrate or chew an aspirin. If you are allergic to aspirin don’t take one. At the hospital, care will include rapid thrombolysis, cardiac catheterization, and angioplasty. They will also administer intravenously clot busting medications.

The risk factors for a heart attack include: smoking, diabetes, high levels of cholesterol, hypertension, family history of heart diseases, atherosclerosis, lack of exercise, obesity, and fast foods (Junk Unhealthy Foods).

Reduce the risks of a heart attack by:

1.    Quitting smoking.

2.    Eating healthy. Avoid fatty foods, excess salt, and red meats.

3.    Controlling high blood pressure and diabetes.

4.     Ensuring regular exercise at least 30 minutes a day. Walking is most beneficial.

5.    Preventing obesity. Doing all you can to maintain weight.

6.    Choosing to live a healthy lifestyle.

7.    Practicing meditation.

8.    Doing regular relaxation and breathing exercises.

9.     Undergoing periodic cardiac evaluations.

10.    Including foods that are rich in anti-oxidants in your diet.

A killer disease, according to the American Heart Association approximately 58.8 million people in the US suffer from heart diseases. And, about 950,000 Americans die of heart ailments each year. Heart diseases and death from it can be prevented by maintaining your health. Find a balance in life between work and other activities, abandon the couch for the outdoors, don’t watch sports on television play sports instead and you can hope to live a long and fulfilled life.

The norm prevention is better than cure could lead a whole world towards good health and well being.

Hypertension

High Blood pressure is the measure of force against arteries. Do you have high blood pressure? Do you know what are common symptoms and signs of high blood pressure? This article will give you comprehensive information about common signs and symptoms of high blood pressure.

How will you come to know that you have high blood pressure?
High blood pressure typically has no symptoms at all, that is why we can call it as Silent killer. Although there are many coincidental symptoms that are widely believed to be associated with high blood pressure. These include headaches, nosebleeds, dizziness, a flushed face and fatigue. Although people with high blood pressure may have many of these symptoms, they occur just as frequently in those with normal blood pressure. Why these symptoms occur. If a person has high blood pressure that is severe or longstanding and left untreated, symptoms such as headache, fatigue, nausea, vomiting, shortness of breath, restlessness, and blurred vision can occur as a result of damage to the brain, eyes, heart and kidneys. In rare cases, high blood pressure may cause brain swelling, which can lead to drowsiness and coma.

If you do not have above symptoms, it does not mean that you have no high blood pressure. Remember most common symptom of high Blood pressure is that ” It Has No Symptom”.

Usually people ignore high blood pressure. Even those who take medicine, only take anti hypertensive medication for short time. Studies have proved that 90% of high blood pressure patients show non compliance with their medication. If you will not control your blood pressure it may lead to serious problems with your Heart, Kidneys, Brain and Eyes. If you want to save these vital organs , then you will have to control your blood pressure with in limits.

Normal blood pressure is less than 120/80. If this reading goes above 140/90 in resting condition, on more than 2 occasions , then you consider yourself as a hypertensive patient. Between 120 and 140 is a pre hypertensive stage. which can be controlled even by natural measures like exercise, low salt intake, stop smoking, lower cholesterol, eat vegetables etc.

Best way to keep you healthy is to have your blood pressure checked at regular intervals.
