Beside cancer, heart disease kills more than 2,000 Americans everyday. Approximately 60 million Americans have heart disease.

I. Causes of Heart Diseases
There are many causes of heart diseases. Most of heart diseases are caused by high blood pressure contributes to hardening of the arteries. High levels of bad cholesterol (LDL) build up in the arteries as a result of uncontrolled diet with high levels of saturated fat and trans fat. All these add to the formation of atherosclerosis lesions and eventually arterial blockage or anything that serves to damage the inner lining of blood vessels and impedes the transportation of oxygen and nutrition to the heart can be defined as a risk of heart disease.

II Symptoms of Heart diseases

Here are some early indication of heart disease symptoms:

1. Leg cramps during walking
Leg cramps during exercise might be caused by dehydration. It is important to drink a lot of fluid during exercise. Leg cramps occur when the muscle suddenly and forcefully contracts. The most common muscles to contract in this manner are muscles that cross two joints. Leg cramps during walking might be an indication of heart disease caused by arteries in your leg being clogged up by cholesterol in result of not enough oxygen being delivered to the cells in your leg.

2. Chest pain
Chest pain is caused by blood vessels in the heart temporarily being blocked up. It is also caused by inadequate oxygen supply to the heart muscle or coronary . The persistence of chest pain would be an early indication of heart diseases.

3. Shortness of breath
Shortness of breath (dyspnea) is the major symptom of the left ventricular insufficiency. People with shortness of breath are four times more likely to die from a heart disease related cause than individuals without any symptoms.

4. Headaches
People see sparkling zigzag lines or loss of vision before a migraine attack may be at particular risk of future cardiovascular problems. Generally headaches do not cause heart diseases but a sudden, explosive onset of great pain might be.

5. Dizziness
Dizziness can have many causes including low blood count, low iron in the blood stream and other blood disorders, dehydration, and viral illnesses. Since there are many different conditions that can produce these symptoms, anybody experiencing episodes of severe headaches or dizziness ought to be checked by your doctor.

6. Palpitations
Palpitations is an extremely common symptom of heart disease. Palpitations are skips in the heart beats and irregular heart beats.

7. Loss of consciousness
It is a common symptom, most people pass out at least once in their lives. However, sometimes loss of consciousness indicates a dangerous or even life-threatening condition such as heart disease so when loss of consciousness occurs it is important to figure out the cause.

There are many more symptoms such as fatigue, memory defects, and changes in skin tone and temperature.

III. Types of Heart Diseases

The heart is a four chambered, hollow muscle and double acting pump that is located in the chest between the lungs. Heart diseases caused by high blood pressure contributes to hardening of the arteries. High levels of bad cholesterol (LDL) build up in the arteries as a result of uncontrolled diet with high levels of saturated fat and trans fat. All these add to the formation of atherosclerosis lesions and eventually arterial blockage.
There are some major types of heart diseases:

1. Type of heart disease affecting heart chambers

As we mention in the previous article, the heart is a four chambered hollow muscle and double acting pump that is located in the chest between the lungs. Heart diseases caused by high blood pressure contributes to hardening of the arteries. High levels of bad cholesterol (LDL) build up in the arteries as a result of uncontrolled diet with high levels of saturated fat and trans fat. All these add to the formation of atherosclerosis lesions and eventually arterial blockage.
In this article, we will discuss heart disease affecting the heart chambers.

Heart failure is caused by the heart not pumping as much blood as it should and so the body does not get as much blood and oxygen that it needs. The malfunctioning of the heart chambers are due to damage caused by narrowed or blocked arteries leading to the muscle of your heart.

There are 4 heart chambers as follow:
