Anxiety and Stress – A Risk of Heart Attack?


One of the most common questions asked with reference to anxiety and stress is whether or not these conditions cause heart disease.

Panic attacks usually involve sudden development of emotions such as anxiety, fear or extreme feeling of discomfort. These emotions are followed by some additional symptoms.

Panic attacks have always been associated to cardiovascular risks such as anger, depression and even hostility. Hypertension is yet another symptom associated to panic attacks. Anxiety or stress is known to add up to adverse effects of cardiovascular problems including enhanced blood clotting tendency, coronary artery spasm or heart rhythm disturbances.

Does stress actually increases the risk of heart attack?

According to a recent research it has been indicated that people with stress or panic disorders tend to possess a more active coagulation System and inhibited fibrinolysis. The result was not expected as there was no injury other than some breaks in the skin occurred due to blood sampling.

This clearly indicates that the clotting was unbalanced. This can be quite dangerous because a coronary artery may get blocked in extreme cases. However, the levels of coagulation measured were just within the range considered normal.

This research came up with an explanation of a data displaying. People with stress or panic disorder being four times more prone to die of a heart attack or stroke. Hence, when there are several other factors including smoking or obesity to enhance the risk of heart disease, a stress disorder can enhance the balance of coagulation further to danger zone.

It is very important to diagnose stress or anxiety disorder as soon as possible. Treatment given at an early stage tends to inhibit the chances of any kind of heart disease.

Anxiety or stress is also known to make a patient get a feeling like heart attack due to rapid pulse and shortness of breath. According to a study of more than three thousand older women, it is suggested that shortness of breath or rapid pulse experienced due to stress may evoke a feeling similar to heart attack and even result in serious heart troubles in the long run.

Studies have also revealed that women who have experienced a full blown panic or stress attack in 6 months were more vulnerable to stroke or heart attack as compared to those who didn´t experienced stress or panic attack.

The researchers also considered a lot of other risk factors such as high blood pressure, smoking, depression and in activity. However, they still came to a conclusion that stress and panic attack enhanced risks of heart related disease.

Women undergoing symptoms of post menopause tend to take a lot of stress and this is known to be one of the major causes of cardiovascular risk. Mental stress is always bad for health and may result in a lot of adverse effects.

A lot of scientific evidences have suggested that metal stress tend to affect the cardiovascular System adversely. Tasks promoting stress can result in blood flow decrease to the heart that ultimately result in a lot of heart related diseases such as a heart attack.

Margarine: Low IQ and Heart Attacks


Margarine lowers the IQ of children. I know it sounds completely arrogant but it is true. According to researchers at the University of Auckland, children who ate margarine every day had significantly lower IQ scores by...

the age of three-and-a-half than those who did not (1). The saddest thing is that margarine is promoted to be a healthy alternative to butter which not true. Margarine is an artificial product that has been heavily processed and chemically refined. Due to these procedures it goes through it has acquired serious toxic and inflammatory properties. The vegetable oils used in most margarine are hydrogenated to make them solid. This turns the oil into highly unhealthy trans-fatty acids. These man-made fatty acids have been shown to raise “bad” cholesterol (LDL) and lower “good” cholesterol (HDL). They have also been linked to inflammation, one of the major causes of heart disease (2).

In another study, people were tracked for 20 years and the number of heart attacks was recorded and analysed (3). Data from the Framingham Study backed up this particular project. The results are in complete disagreement with everything we have been told so far. As margarine consumption increased, heart attacks went up. As butter consumption increased, heart attacks declined. During the second decade, the group eating the most margarine had 77% more heart attacks than the group eating none!

The Framingham Study is considered to be the research project backing up the conventional theories for heart disease and cholesterol for many decades now. After 40 years, the director of the Framingham Study admitted: "In Framingham, the more saturated fat one ate, the more cholesterol one ate, the more calories one ate, the lower the person's serum cholesterol. . . we found that the people who ate the most cholesterol, ate the most saturated fat, ate the most calories, weighed the least and were the most physically active."

I guess that the point to take home from the above studies, is that things are not always the way they are presented by the media. It has become imperative to be very careful when we choose our sources of information concerning health issues.

Managing Your Cholesterol - The Best Way To Prevent Hearth Attacks

Cholesterol is one of the most familiar medical words today. Everyone knows “something” about it , but mostly cholesterol is associated in our mind with something “bad” and “unwanted” that happens to old and overweight people.The facts show that about...

20 percent of the U.S. population has high blood cholesterol levels.

Actually cholesterol is a waxy, fatlike substance (lipid) that your body needs for many important functions, such as producing new cells , some hormones, vitamin D, and the bile acids that help to digest fat.. It is present in cell walls or membranes everywhere in the body, including the brain, nerves, muscle, skin, liver, intestines, and heart.

In fact our bodies need cholesterol to function normally, but too much cholesterol can be bad for our health. Why ? Cholesterol and other fats can't dissolve in the blood. They have to be transported to and from the cells by special carriers. Cholesterol travels through your blood attached to a protein. This cholesterol–protein package is called a lipoprotein. Lipoproteins are high density or low density depending on how much protein there is in relation to fat.

Low-density lipoprotein (LDL) is the major cholesterol carrier in the blood. If too much LDL cholesterol circulates in the blood, it can slowly build up in the walls of the arteries feeding the heart and brain. Together with other substances it can form plaque, a thick, hard deposit that can clog those arteries. When the coronary arteries become narrowed or clogged by cholesterol and fat deposits (a process called atherosclerosis) and cannot supply enough blood to the heart, the result is coronary heart disease. If the blood supply to a portion of the heart is completely cut off by total blockage of a coronary artery, the result is a heart attack. This is usually due to a sudden closure from a blood clot forming on top of a previous narrowing. Low-density lipoprotein cholesterol is called "bad" cholesterol because it can cause cholesterol buildup and blockage of your arteries. LDL is mostly fat with only a small amount of protein.

About one-third to one-fourth of blood cholesterol is carried by high-density lipoprotein (HDL). Medical experts think HDL tends to carry cholesterol away from the arteries and back to the liver, where it's passed from the body. Some experts believe HDL removes excess cholesterol from plaques and thus slows their growth. HDL is called "good" cholesterol because it helps prevent cholesterol from building up in your arteries. It is mostly protein with only a small amount of fat.

Since there is good cholesterol and bad cholesterol it is not only necessary to know your cholesterol level ,it is also important to know your levels of LDL and HDL.

The fact is that there are no symptoms of high cholesterol. Your first symptom of high cholesterol could be a heart attack or a stroke. The level of cholesterol can be measured only with a blood test.The results come as three main numbers:

· Total Cholesterol
· LDL
· HDL

The level of LDL should be less than 160.

Total cholesterol should be less than 200.

The level of HDL should be more than 35.

Most Important: Your LDL level is a good indicator of your risk for heart disease. Lowering LDL is the main aim of treatment if you have high cholesterol. In general, the higher your LDL level, the greater your chance of developing heart disease.

Remember : Regular cholesterol tests are recommended to find out if your cholesterol level is within normal range.

WHAT CAN YOU DO ABOUT YOUR LDL CHOLESTEROL LEVELS?

The main cause of high blood cholesterol is eating too much fat, especially saturated fat. Saturated fats are found in animal products, such as meats, milk and other dairy products that are not fat free, butter, and eggs. Some of these foods are also high in cholesterol. Fried fast foods and snack foods often have a lot of fat.

Being overweight and not exercising can make your bad cholesterol go up and your good cholesterol go down. Regular physical activity can help lower LDL (bad) cholesterol and raise HDL (good) cholesterol levels. It also helps you lose weight. You should try to be physically active for 30 minutes on most, if not all, days.

Cigarette smoking damages the walls of your blood vessels, making them likely to have cholesterol rich plaques rupture and have heart attacks. Smoking may also lower your level of HDL cholesterol by as much as 15 percent.

Also, after women go through menopause, their bad cholesterol levels tend to go up. There is also a rare type of inherited high cholesterol that often leads to early heart disease.Some people inherit a condition called familial hypercholesterolemia, which means that very high cholesterol levels run in the family.Other people, especially people for whom diabetes runs in the family, inherit high triglyceride levels. Triglycerides are another type of blood fat that can also push up cholesterol levels. People with high blood triglycerides usually have lower HDL cholesterol and a higher risk of heart attack and stroke. Progesterone, anabolic steroids and male sex hormones (testosterone) also lower HDL cholesterol levels.

So we can make a conclusion that the main therapy is to change your lifestyle. This includes controlling your weight, eating foods low in saturated fat and cholesterol, exercising regularly, not smoking and, in some cases, drinking less alcohol.

But , depending on your risk factors, if healthy eating and exercise don't work after about 6 months to 1 year, your doctor may suggest medicine to lower your cholesterol level.

Now there are very effective medications called “statins”,such as Lipitor.

The drug works by helping to clear harmful low density lipoprotein (LDL) cholesterol out of the blood and by limiting the body's ability to form new LDL cholesterol. Each tablet Lipitor includes 20mg Atorvastatin. It is in a class of medications called HMG-CoA reductase inhibitors. It works by slowing the production of cholesterol in the body. Lipitor has shown the ability to halt, not just slow, the potentially fatal buildup of plaque in clogged arteries. While a handful of drugs now available slow the buildup of new plaque, or atherosclerosis, in coronary arteries, no drug on the market has been proven to both stop new build-up and clear existing plaque.

So if you are loosing the battle with LDL levels , you can visit my site http://www.craforhealth.com/cholesterol.html, dedicated in the effective medical care , to find the proper treatment for your disease.
