Lipidfiltration (lipid filtration) Technology

Lipidfiltration (lipid filtration) Technology

According to research,  1 in every 10 people suffers from high cholesterol, which may result in hyperlipidemia.  Any blood vessel in our body will lead may subject to hardening of the arteries because of the high cholesterol. Symptoms of mild coronary artery diseases include angina (chest pain) ; severe heart attack will lead to death.

Lipidfiltration techonology is to use filter tubes to remove bad cholesterol and bring cleansed blood back to the body. Lipidfiltration technology has been used to for almost 30 years to mainly to avoid blockage,  stroke, myocardial infarction and other serious complications. Lipidfitration technology may also be used to help systemic lupus erythematosus patients in the emergency cerebral hemorrhage and myasthenia gravis.

Once the level of cholesterol reaches 200 milligrams per one milliliter, physicians will ask the patients to reduce  intake of cholesterol through a low-cholesterol diet (crude fiber, brown rice, etc.) and the increase metabolism in cholesterol by exercising.  Medication will be prescribed if necessary. When the above mentioned treatments result in no improvement, the lipidfiltration technology will be next.

The lipidfiltration procedure  takes about three hours. The patient blood are drawn from the vein on the left elbow and separated out by the filters to remove low and very low density lipoprotein, which are  bad cholesterol, the cleansed blood will be brought back in the body through the vein on the right elbow. Chest tightness and weakness will gradually disappear during the procedure. Although lipidfiltration will result in immediate improvement, however, after all, it is invasive. Side effects such as high blood pressure or allergies may occur. Patients should remain in low cholesterol diet, continue exercise, and take medication as directed.

Coronary Artery Bypass Graft

What is Coronary Artery Bypass Graft (CABG)?

Coronary Artery Bypass Graft (CABG) surgery is to graft normal blood vessels to  the heart by  connecting the main artery and the normal arteries,  bypassing the coronary artery stenosis.  The situation is just like a bridge erected , so that blood can once again go through to supply oxygen to relieve the myocardial condition.
CABG surgery patients will go under general anesthesia. The doctor will first cut the patient's  chest median sternotomy incision. The right atrial venous drainage tube is inserted, blood will be drained into the cardiopulmonary bypass machine, after adding oxygen, then it will flow back into the patient's body. In addition, to ensure that the surgery is completed under the state without blood, the doctor will clamp the aorta to suspend blood flow, the heart will be will during the period. 2-4 blood vessels will usually be grafted during a bypass surgery, it will take about 3-4 hours.
Leg saphenous vein is commonly used in CABG; because it is long, it can be used for multiple bypass. Many patients are worried that removal of a blood vessel from the leg will affect the ability to walk. In fact, this does not affect the leg's function. Data show that 60% of patients' bypass remain smooth 10 years after the surgery; 50% of patients' bypass had become moderately narrow.  This is because as time goes by the proliferation of cells in the vascular wall adhesion that results in vein narrowing. In recent years, invasive surgical techniques can be applied to this surgery.
More and more people use  mammary artery in the breast in CABG. The 10-year rate has increased from 60% to 90%. However, due to the limited length of mammary artery, it is only suitable for CABG that goes through the front the heart. In addition, in recent years an increasing number of radial forearm have been used in bypass surgery in younger patients.

Common Drugs for Coronary Heart Disease

Common Drugs for Coronary Heart Disease
If   blood vessel blockage is not serious, surgery is not required.  The condition  can be treated with drugs.  Drugs may  reduce cardiac oxygen consumption to  reduce heart beat rate and  lower blood pressure  or increase expansion of coronary artery,  so that narrow blood vessels may expand. However, there is no drug that can fully expand narrowed  blood vessels to normal conditions.

Commonly used drugs  include aspirin and Clopidogrel. Aspirin is an anti-platelet drug, an invention of  heart-shaped receptor blockers and angiotensin converting enzyme inhibitors in serum (ACEinhibitor) .  It is for  myocardial ischemia caused by coronary heart disease symptoms and treatment of complications.

When patients experience unstable angina during drug treatment, they  may need to go through  a  coronary angioplasty  operation. When there is a  heart attack, patients may have the following symptoms: angina, pain in the heart of the front,  feeling of oppression, and sometimes the pain will be transmitted to the chin, back, shoulders, the patient may have asthma during angina, dizziness , symptoms of heart disorder and so on.

Coronary Heart Disease Causes

Coronary Heart Disease Causes

As the coronary arteries around the heart become narrow and blocked, it impedes blood circulation. Thus, nutrients cannot be transported to the heart, causing coronary heart disease. The factors include:

  • Diseases - hypertension, high cholesterol, and diabetes will lead to coronary heart disease. The majority of coronary heart disease is caused by arteriosclerosis; blood fats in the blood, such as long-term accumulation of cholesterol in the blood vessel wall, forming a similar mucus-like mush,  it narrows blood vessels and loses their elasticity, hardening and swollen thickness of the blood block blood vessels, leading to myocardial ischemia and infarction.
  • Obesity
  • Lifestyle - lack of exercise, life stress, etc.
  • Eating habits - consuming too much high fat, high cholesterol foods or alcohol; both will increase blood cholesterol and harden arteries, and increase the chances of  high blood pressure.
  • Smoking
  • Aged
  • Genetic

Coronary Heart Disease Symptoms

Coronary heart disease symptoms

Brief chest pain (angina) is the most prominent symptoms of coronary heart disease. Risk of coronary heart disease is that patients may lose their lives in a short time, some of them may not have experienced any chest pain.  Since there are very few visible signs for heart diseases, therefore, pay careful attention when you see the following symptoms:

1. Stable angina pectoris

Usually when playing  sports or walking up the stairs, an attack of  chest pain may be associated with pain on the left arm or left side of the neck.  Symptoms can be relieved by taking a break.

2. Unstable angina pectoris

The pain may attack you at any time, even when the body is at a stable state. In some serious conditions, when the blood vessels get so narrowed and the condition becomes cardiac embolism; angina becomes frequent, prolonged and intense. Chest pain may spread to the neck, arm and jaw; the patient will experience a lot of sweating, shortness of breath, tightness, vomiting, dizziness, coma, or even die. Even if  treated immediately,  there may also be all kinds of complications that may lead to  death.

It is estimated that about ten percent of patients did not have any symptoms;  symptoms may not be found even in physical examinations. When the condition becomes serious, patients may die with no signs at all.

What is Coronary Heart Disease?

What is Coronary Heart Disease?
Coronary heart disease is also known as "the invisible killer," patients may show no symptoms before s/he dies.  Some patient's blood sugar, blood pressure and cholesterol exceeded the permitted level and has been on  medication, however, may still result  serious vascular thrombosis, or in need of life-saving surgery.

The heart is located inside the chest cavity between the lungs.  It constantly beats every minute, which provide the main force for the blood circulation. Although the heart itself contains blood, it requires the blood to  supply oxygen and nutrients in order for it to function properly. This depends  on the two great vessels near the heart - coronary artery, to supply blood to the blood vessels around the heart. Its network and branch surfaces shape like a crown covering the heart. If, for whatever reason, the coronary blood circulation is affected and leads to lack of blood supply to the heart and results in inadequate supply of oxygen and nutrients, the heart's function will become impaired, and this is the cause of coronary heart disease.
