Angina pectoris
Angina pectoris commonly known as angina, is chest pain due to a lack of blood and hence oxygen supply to the heart muscle, generally due to obstruction or spasm of the coronary arteries. Coronary artery disease, the main cause of angina, is due to atherosclerosis of the coronary arteries. The term derives from the Greek ankhon (”strangling”) and the Latin pectus (”chest”), and can therefore be translated as “a strangling feeling in the chest”.

Asymptomatic
In medicine, a disease is asymptomatic while the patient does not experience any noticeable symptoms. Asymptomatic diseases may not be discovered until the patient undergoes medical tests. Some diseases remain asymptomatic for a remarkably long time.

Atherosclerosis
Atherosclerosis is a disease affecting arterial blood vessels. It is a chronic inflammatory response in the walls of arteries. It is commonly referred to as a “hardening” or “furring” of the arteries. It is caused by the formation of multiple plaques within the arteries. These plaque deposits lead to a restricted blood flow to the heart. Therefore, less oxygen and other nutrients reach the heart muscle. This may lead to angina pectoris or to a heart attack.

Atheroma
In pathology, an atheroma is an accumulation and swelling in artery walls that is made up of cells or cell debris, that contain lipids (cholesterol and fatty acids), calcium and a variable amount of fibrous connective tissue. In the context of heart or artery matters, atheromata are commonly referred to as atheromatous plaques (please see plaque).

Catheter (balloon or PTCA catheter)
In medicine a catheter is a tube that can be inserted into a body cavity, duct or vessel. Catheters thereby allow drainage or injection of fluids or access by surgical instruments. The process of inserting a catheter is catheterization. A balloon catheter is a type of “soft” catheter with an inflatable “balloon” at its tip which is used during a catheterization procedure to enlarge a narrow opening or passage within the body. The deflated balloon catheter is positioned, then inflated to perform the necessary procedure, and deflated again in order to be removed.

Circulatory System
The circulatory system is extremely important for sustaining life. Its proper functioning is responsible for the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide and waste products, maintenance of optimum pH, and the mobility of the elements, proteins and cells of the immune system. In developed countries, the two leading causes of death, myocardial infarction and stroke each may directly result from an arterial system that has been slowly and progressively compromised by years of deterioration (see atherosclerosis).

Computed tomography (CT)
Computed tomography is a medical imaging method employing tomography. Digital geometry processing is used to generate a three-dimensional image of the inside of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation. The word “tomography” is derived from the Greek tomos (slice) and graphein (to write).

Coronary artery disease (CAD)
CAD is also called coronary heart disease (CHD) or atherosclerosis, is the end result of the accumulation of atheromatous plaques within the walls of the arteries that supply oxygen and nutrients to the myocardium (the muscle of the heart). The restricted blood flow may lead to angina pectoris or a heart attack.

Coronary angiography
Angiography or arteriography is a medical imaging technique in which an X-ray picture is taken to visualize the inner opening (lumen) of blood filled structures, including arteries, veins and the heart chambers. Its name comes from the Greek words angeion, “vessel”, and graphien, “to write or record”.

Coronary angioplasty (PCI or PTCA)
Coronary angioplasty (also known as percutaneous coronary intervention, PCI or percutaneous transluminal coronary angioplasty, PTCA) is a therapeutic procedure to treat the stenotic (narrowed) coronary arteries of the heart found in coronary artery disease. Angioplasty is the mechanical widening of a narrowed or totally obstructed blood vessel. These obstructions are often caused by atherosclerosis. The word is composed of the medical combining forms of the Greek words aggeios meaning “vessel” and plastos meaning “formed” or “moulded”. Angioplasty is typically performed in a minimally invasive or percutaneous method.

Coronary artery bypass graft surgery (CABG)
CABG also called heart bypass or bypass surgery is a surgical procedure performed to relieve angina and reduce the risk of death from coronary artery disease. Arteries or veins from elsewhere in the patient’s body are grafted to the coronary arteries to bypass atherosclerotic narrowing and improve the blood supply to the coronary circulation supplying the myocardium (heart muscle).

Contrast agent
Radiocontrast agents (also simply contrast agents or contrast materials) are compounds used to improve the visibility of internal bodily structures in an X-ray image.

Every day the average heart beats (widening and narrowing) to 100,000 times and able to pump approximately 2000 liters of blood. If until the age of 70 years, the human heart will beat 2.5 billion times as much non-stop.
Atherosclerosis comes from the Greek, which means athero is clay, and sclerosis, meaning hardening. This term is used to label a process in which a collection of fatty substances, cholesterol, cellular waste, calcium and fat compounds formed on the inside of the artery wall. This formation is often also called plaque. Generally affects the large arteries and medium size. Naturally, hardening of the arteries also occurs when we age.
Angina, is a condensation of “angina pectoris” is a Latin language to express pain in the chest. Basically, angina is a feeling pressured, uncomfortable or painful neck, shoulders back, and arms. Angina attacks usually occur for a few minutes and will disappear when we rest and take medicine.
Myocardial Infarction, is used to express a heart attack. Is due to blockage of blood flow in one or more branching arteries that supply oxygen-rich blood to the heart muscle. Termination of oxygen-rich blood flow to the heart muscle can cause permanent damage to the heart muscle. Somewhat different from the pain of angina, heart attack pain will generally last more than 15 minutes and not relieved by rest.
PTCA, an abbreviation of Percutaneus Transluminal Coronary Angioplasty, which means; through the skin (percutaneus), in the vessel (transluminal), which related to the blood vessels of the heart (coronary) and blood vessel dilation (angioplasty)
PCI, which stands for Coronary Intervention Percutaneus meaningful treatment with stent stenosis.
Stenosis, derived from the Greek shorthand which means narrowing. This term describes the narrowing of the arteries by atherosclerosis plaques. Generally, coronary stenosis diagnosed at advanced stages, where the stenosis was 75% reduced blood flow.
Restenosis, is a term used to describe the narrowing of the back of a blood vessel, which at that location previously dilaksakan Ballon Angioplasty with stents or installation
Drug Eluting stents (DES), is a type of heart stents drug dilapisis surface. Drugs found on the surface of the DES is intended to prevent the emergence of Restenosis.

Coronary Heart Disease ( Information for Patient)

Causes – Diagnosis – Treatment

The heart’s like a pump work consisting of several rooms. Heart organ covered with muscles and with a variety of blood vessels in and out. The flow of blood from the lungs, where blood in the oxygen, flowing into the heart and pumped out to all parts of the body.

When the blood has been sent that contain oxygen to body tissues, they will return to the heart and is pumped back into the lungs.

The heart needs more oxygen to function optimally. But there is blood in the heart of the room itself is not functioning to supply oxygen to the heart muscle.

Special blood vessels in the outer parts of the heart, called coronary arteries, in charge of supplying the oxygen-rich blood and nutrients to the heart muscle to function properly. Three major blood vessels and blood vessels are much smaller this task.

When one or more blood vessels are blocked (usually due to the formation of blood clots in the lumen of blood vessels), blood will not reach the heart muscle at the bottom of the blockage, preventing the supply of oxygen to the heart muscle.

Coronary Heart Disease

Coronary heart disease usually caused by the emergence of “atherosclerosis (hardening of the arteries), a process in which deposits of fatty material containing cholesterol (plaque) formed along the artery walls. When plaque is formed, blood vessels become narrowed.

The Causes of Coronary Heart Disease

Although Coronary Heart Disease seems to be a part of natural aging on arterial blood vessels, but he’d formed at different speeds on each person, based on a variety of factors as follows:

High blood pressure
Blood cholesterol levels are abnormal
The habit of smoking
Diabetes
Men
Obesity
Lack of exercise
Family history with Coronary Heart Disease

Each of these factors can damage blood vessels and / or accelerate the formation of plaque.

Consequences

Narrowing of blood vessels, are not capable of delivering oxygen-rich blood to the heart muscle is required for activity, and this will lead to a situation that is called angina.Angina usually occurs after the patient perform physical activity or stress, when the heart muscle must work harder and requires more oxygen, such as:

Exercising
Physical activity is more severe
Eat (fatty and alcoholic beverages)
Experiencing stress is accompanied by a sudden spike in blood pressure

Angina is not the same as a heart attack, but a symptom of a heart disease in general and occurs when the arteries have narrowed by plaque that is not capable of supplying oxygen to the heart muscle (blood flow is reduced). If the coronary artery becomes blocked total (there was no blood flow), blood flow to the heart muscle will stop, and a heart attack (Myocardial Infarction) can occur, which would cause damage to our heart.

The doctor will perform various tests to diagnose Coronary Heart Disease, through:

An electrocardiogram (EGG or EKG) that measures the electrical activity of our heart. This test can show a part of the heart muscle that have experienced damage from a heart attack.
Stress Test, to record the electrical activity when our physical activity and can be the basis of information abgi doctor if part of the heart has been damaged.
Heart Catheterization (Angiography) is an act performed by a cardiologist in Catheteriazation Lab. This action requires a contrast dye squirted into the arteries that will appear at the time of X-rays emitted. This procedure can show if there has been a blockage or narrowing of heart arteries. So that the doctor can determine what actions should be implemented.

Management of Coronary Heart Disease.

Management of Coronary Heart Penyakti can be done through a combination of lifestyle changes and physical activity, diet, and Action Medical. Nitroglycerin generally be granted if the patient complains of pain arising in the chest, but please note this drug is not intended to treat the blockage itself:

Dilation with balloon / balloon dilatation (PTCA)
Installation of heart stents (PCI)
Arterial vein graft Shortcuts (CABG)

Determining which actions to be taken, based on the general condition of the patient and the level of damage, and the number of blockages that occur in heart arteries.

1. Balloon dilatation (PTCA)

Development of coronary artery heart is invasive measures undertaken to widen a clogged artery. PTCA is the medical term most often used.

At the time of PTCA, a catheter (very small tube, and subtle) is equipped with a balloon diujungnya, will be inserted through a vein (usually in the groin area) and are encouraged to enter into the heart arteries are narrowed. The balloon will be developed gradually, so as to suppress the fat tissue that causes narrowing of blood vessels and arteries dilate.

2. Installation of heart stents (PCI)

Many patients who have been executed with balloon dilation (PTCA) will experience a narrowing of the back or called restenosis, the treated area. Heart stent could reduce the risk of blockage or narrowing again after PTCA.

Heart stent is a cinicin that can be developed and made of metal (non-stainless steel or cobalt-chromium metal). This stent will be attached to a balloon and inserted similar to the action PTCA. When the balloon expanded, a stent will also be widened, and then locked in a blockage and will serve as a permanent buffer. Stent is what will keep narrowing of the arteries that remain open. So a stent in the artery will be permanently, holding the blood vessels so that blood flow to the heart muscle no longer disrupted.

3. Arterial vein graft Shortcuts (CABG)

Arterial vein graft Shortcuts (CABG) surgery is performed for patients with Coronary Heart Disease, to overcome angina and reduce the risk of heart attack.

A vein or artery from another part of the patient’s body will be grafted from the aorta to the heart arteries, to be a shortcut blockage caused by atherosclerosis and will increase blood flow to the myocardium (heart muscle)
