Coronary heart disease and the causes

Heart is a muscular organ, cone-shaped, hollow and with the base above and below the peak. Apex its (peak) sloping to the left. Heart weight of approximately 300 grams. To have the heart to function as an efficient blower, muscle, heart muscle, and the hollow cavity on the bottom of the contraction should conduct alternately. Fast-throbbing heart rate or the pump is working is a naturally by "the rhythm". This consists of a group specifically called nodus sinotrialis, which is located right inside the foyer wall. An electrical impulse is transmitted from the nodus sinotrialis to create a second platform berkontraksi both simultaneously. Electric current is then forwarded on to the chamber walls, which in turn create room to room-contraction simultaneously. This period of contraction called systole. Next period is followed by a short period of relaxation - approximately 0.4 seconds - which is called diastole, before the next impulse came. Nodus sinotrialus produce between 60 to 72 impulse like this every minute when the heart is being relaxed. Impulse impulse-production also is controlled by a system of nerve called the autonomous nerve system, which we desire to work outside. System built-in power this is the contraction of heart muscle contraction, which is called heart rate.

Heart disease is a disease of the blood vessel system, or more precisely the heart-muscle and blood vessel, heart pentakit some examples such as coronary heart disease, heart attack, high blood pressure, stroke, pain in the chest (usually called "angina") and diseases heart rheumatism.

The cause of the occurrence of heart disease are:

* High blood pressure.
* Cholesterol.
* Smoking.
* Obesity (excess body weight).

"Coronary heart disease" is the highest in the suffering people. This disease attacks the blood vessel and can cause a heart attack. Heart attack due to arterial duct that clog, obstruct the distribution of oxygen and nutrients to the heart. Stroke is caused by a lack of flow of blood that flows to the brain, or sometimes cause bleeding in the brain.

However, not all heart disease is caused by terserangnya vein, here is some other disturbance in the heart:

* Abnormal Heart Rhythms
Normally the heart rattle 60 to 100 times a minute (or sekiar 100 thousand times each day). Bedetak heart that is not usually called normal arryhytmia (often also called dysrhythmia). The heart of the rattle too slow (under 60 times per minute) is called bradyarrhythmias. While the rattle above 100 per minute is called tachyarrhytmias.
* Heart Failure
Or heart failure is the most frightening. Not mean that the heart can not work at all, just the heart does not rattle as appropriate
* Heart Valve Disease
Damaged heart valve. Heart valve located in each chamber heart (our heart has 4 fruit room) to set up a working direction of blood flow to the heart.
* Congenitas Heart Disease
Regular or called in the heart rudiment. The 8 to 10 children of each birth in 1000. Early symptoms are usually terldeteksi at birth or in infancy. In the United States about 500 thousand people experienced in the heart rudiment growth and increases sektar 20 thousand orangtiap year.
Cardiomyopathies *
Attack on the heart muscle itself. The people that this disease usually mengalamai enlargement, diminution of the heart and is not normal or even become numb. The heart is not pumping the normal (become weaker). Without a good handling cardiomyopathies akan menyebabakan disease is worse, such as heart failure or cause a normal heart does not rattle.
Pericarditis *
Inflammation is a layer of the heart girth. Rare, usually caused by infection.

The factors that cause someone is exposed to coronary heart disease:


* Entering the age of 45 years for men. It is very important for men to realize their vulnerability and take positive action to prevent any future heart disease.

* For women, entered the age of 55 years or experience early menopause (as a result of the operation). Women began to overtake men in terms of risk of heart disease after the menopause

* Historical heart disease in families. Historical heart attack in the family is often a result of the cholesterol profile that is not normal.

* Diabetes. Most diabetics die not because of increased blood sugar level, but because the condition of their heart complications.

* Smoking. Drai heart disease risk equivalent to smoking 100 pound excess body weight - so may not equate the two.

* High blood pressure (hypertension).
* Obesity (Obesity). Obesity middle (stomach bulging) is a form of obesity. Although all the fat tends to have a risk of heart disease, people with middle Obesity moreover.

* Lifestyle bad. A bad lifestyle is one of the root causes of heart disease - and replace them with physical activity is one of the most radical step that can be taken.

* Stress. Many studies have shown that, when the situation is tense, the heart can occur arithmias which endanger lives.
