Coronary heart disease is caused by the build-up of artherosclerosis, [fatty deposits] or plaque on the inside of artery walls. This narrows the channel inside the artery so there is less room for the blood to flow through.
The following 2 critical risk factors you should be aware of if you wish to avoid a heart attack or heart disease.
SMOKING.
Stopping smoking is the single most important thing you can do to reduce your risk of heart disease, according to the Heart Foundation. Smoking reduces the amount of oxygen in your blood, damages and constricts your artery walls and increases blood pressure. It also increases your heart rate, and can increase the rate at which cholesterol deposits accumulate in the blood vessels.
For many smokers, fear is a major factor. Fear of giving up the pleasure or the crutch, fear that you will be unable to enjoy life or handle stress. A number of strategies are available. These include patches as well as psychotherapy and hypnotherapy.
The benefits of quitting however, are almost immediate. From the moment you stop smoking, your extra risk of heart disease begins to decrease. One year after stopping, your risk of another heart attack is around half that of a continuing smoker.
LACK OF PHYSICAL ACTIVITY.
Your body is designed to move.Therefore regular moderate physical activity is good for your heart. Being active can be fun, make you feel good in yourself and help boost your immune system. Physical activity can also help control other risk factors such as blood pressure and weight.
The Heart Foundation recommends 30 minutes or more of physical activity [such as brisk walking] on most days of the week. If you don't have time for a 30 minute block, take three 10 minute walks and accumulate in shorter bouts.
Walking 19km a week is enough exercise to improve cardiovascular health, according to a US study published in the October 2005 issue of the journal Chest.
Researchers at Duke University Medical Centre found that overweight people who walked 19km a week, considered by the scientists to be a "moderate" amount of exercise, consumed oxygen more efficiently and gained physical endurance, both of which reduced the risk of heart disease.
The most important factor is to pace yourself. If you have difficulty talking after exercise, you may be over exerting. A good test for this is the target heart rate for your age and this is calculated by using a heart rate monitor.
A heart rate monitor is a good way to measure the intensity and quality of your workouts and maximise your outcomes. You use percentages of you maximum heart rate [MHR] to judge the intensity for you. To work out your MHR you simply deduct your age from 220. About 50 to 60 percent of your MHR is a good level for improving your overall health. Once you hit 60 to 70 percent, you're in the "fitness zone" This is perfect for those looking to train at a moderate intensity.
Seventy to 85 percent is about the fastest pace at which you can exercise and still talk. This is great for runners wanting to improve performance. Don't go higher than this, 85 to 100 percent is a zone best reserved for serious athletes with a high pain tolerance.
But there's a lot more to the story.
The truth is, cholesterol is just one risk factor for heart disease. And it's not even the most important one. You see, cholesterol isn't all bad. In fact, you'd die without it.
This fatty substance produced by the liver helps keep your body running smoothly by building cell membranes and maintaining hormone levels. Even more surprising, lowering cholesterol doesn't necessarily improve health.
Research has even linked LOW levels of cholesterol to a higher risk of death in older people. For some of us, lowering cholesterol may do more harm than good, since higher amounts of cholesterol may actually protect against death.
When it comes to cholesterol, its role in heart disease isn't the only myth. Here's another one: "A high-fat diet causes cholesterol problems." Again, the truth is more complicated than that. That's because the TYPE of fat you consume matters much more than how MUCH of it you eat.
Trans fats or hydrogenated fats and saturated fats promote abnormal cholesterol, while omega-3 fats and monounsaturated fats can help lower cholesterol and improve the type you do have. Fat isn't the bad guy here. Instead, it's sugar. And your body turns sugar into fat.The biggest source of abnormal cholesterol is not fat -- it's sugar, which your body converts to fat.
One kind of sugar is worse than the others. That's high-fructose corn syrup, or HFCS. You'll find HFCS in sodas, many juices, and most processed foods. But HFCS isn't so sweet: It's the main dietary cause of cholesterol problems.
While we're on the subject of myths, let's talk about total cholesterol. It is NOT the most critical aspect of cholesterol. And lowering cholesterol may not be the answer. That's because you want your HDL ("good") cholesterol levels to be higher, not lower.
It turns out that many different facets of cholesterol make a difference in your health. These include your levels of HDL ("good") vs. LDL ("bad") cholesterol; your triglyceride levels; your ratio of triglycerides to HDL; and your ratio of total cholesterol to HDL. That's a lot of things to consider -- but there's more.
When it comes to cholesterol and triglycerides, size matters, too. In this case, bigger is better. Cholesterol particles that are large and fluffy are generally safe, even if you have high cholesterol. Smaller particles are more dangerous because they can easily penetrate arteries. Your cholesterol can also become rancid, or oxidized, which can be unhealthy. Oxidative stress and free radicals can trigger inflammation. And when small LDL particles become rancid, they lead to plaque and cholesterol buildup in your arteries.
So cholesterol isn't the only cause of cardiovascular disease. And lowering cholesterol doesn't always make a difference in your risk. Instead, cardiovascular problems occur when your body functions get out of whack. The result: Inflammation, blood sugar imbalances, and oxidative stress. Simply put, your risk is determined by the way that your genes interact with your lifestyle and environment. These factors need to stay balanced, or your risk for heart disease will increase. One major risk factor for heart disease is inflammation.
In one major study, Harvard researchers found that people with high levels of a marker called C-reactive protein (CRP) had higher risks of heart disease than people with high cholesterol. People who had lower cholesterol levels didn't protect those with high CRP. The risks were greatest for those with high levels of both CRP and cholesterol.
Insulin resistance (also called metabolic syndrome or pre-diabetes) also increases the risk of heart disease, by causing blood sugar imbalances and high levels of insulin. High levels of a substance called homocysteine may also lead to cardiovascular illness.
All of these conditions can lower cholesterol, but not the way you'd like. The cholesterol that they lower is the good kind -- and lowering that is bad! They also boost your triglycerides, increasing inflammation and oxidative stress -- and triggering cardiovascular disease. So what can you do?
There is good news. These factors can arise from poor diet, nutritional imbalances, stress, and lack of activity -- all of which are under your control. Changing these factors can help lower cholesterol, as well as other risks for heart disease. But before you can start a comprehensive program to lower your risk of heart disease, you need to determine your overall risk. Ask your doctor about the following tests.
* Total, HDL, and LDL cholesterol, and triglycerides. Your total cholesterol should be under 200; triglycerides under 100; HDL over 60; LDL under 80. Your ratio of total cholesterol to HDL should be less than 3.0. Your ratio of triglycerides to HDL should be no greater than 4.
* NMR Lipid Profile. This looks at your cholesterol under an MRI scan to assess the size of the particles.
* Cardio C-reactive protein. This should be less than 1.
* Homocysteine. Your homocysteine should be between 6 and 8.
* Lipid peroxides or TBARS test, which looks at the amount of oxidized or rancid fat.
* Fibrinogen, which looks at blood clotting. It should be less than 300.
* Lipoprotein (a), can promote the risk of heart disease, often in men. It should be less than 30.
* Genes or SNPs including Apo E, cholesterol ester transfer protein, and MTHFR genes.
* High-speed CT or (EBT) scan of the heart may be helpful. Scores higher than 100 are a concern.
As you can see, cholesterol is important -- but it isn't the most important risk for heart disease. Likewise, lowering cholesterol isn't the only answer. By getting tested, you'll get a better picture of your true heart disease risk. Then you'll be ready to start lowering cholesterol AND your other risk factors so you can improve your health -- today.
