heart disease?

Question

causes, symtoms, prevention, treatment, etc

Answer 1

Heart disease is the narrowing or blockage of the arteries and vessels that provide oxygen and nutrient-rich blood to the heart. It is caused by atherosclerosis, an accumulation of fatty materials on the inner linings of arteries that restricts blood flow. When the blood flow to the heart is completely cut off, the result is a heart attack because the heart is starved of oxygen.

Heart disease, also called coronary heart disease or coronary artery disease, is the leading cause of death for both men and women in the United States. According to the American Heart Association, deaths from coronary artery disease have declined somewhat since about 1990, but more than 40,000 people still died from the disease in 2000. About 13 million Americans have active symptoms of coronary artery disease.

Heart disease occurs when the coronary arteries become partially blocked or clogged. This blockage limits the flow of blood through the coronary arteries, the major arteries supplying oxygen-rich blood to the heart. The coronary arteries expand when the heart is working harder and needs more oxygen. If the arteries are unable to expand, the heart is deprived of oxygen (myocardial ischemia). When the blockage is limited, chest pain or pressure called angina may occur. When the blockage cuts off the blood flow, the result is heart attack (myocardial infarction or heart muscle death).

Healthy coronary arteries are open, elastic, smooth, and slick. The artery walls are flexible and expand to let more blood through when the heart needs to work harder. The disease process is thought to begin with an injury to the linings and walls of the arteries. This injury makes them susceptible to atherosclerosis and production of blood clots (thrombosis).

Causes & Symptoms

Heart disease is usually caused by atherosclerosis. Cholesterol and other fatty substances accumulate on the inner wall of the arteries. They attract fibrous tissue, blood components, and calcium. They then harden into artery-clogging plaques. Atherosclerotic plaques often form blood clots that can also block the coronary arteries (coronary thrombosis). Congenital defects and muscle spasms of arteries or heart muscles also block blood flow. Recent research indicates that infection from organisms such as chlamydia bacteria may be responsible for some cases of heart disease.

Treatment methods differs from Patient to Patient and your Cardiologist will be the best judge to tell you on evaluating the position. Please consult your Cardiologist-

Answer 4

Coronary heart disease is caused by any problem with the coronary arteries that keeps the heart from getting enough oxygen- and nutrient-rich blood. The most common cause by far is atherosclerosis. Lack of sufficient blood is called ischemia, so coronary heart disease is sometimes called ischemic heart disease.
The most devastating sign of coronary heart disease is abrupt, unexpected cardiac arrest.

*Cardiac arrest commonly occurs in people who have had previous heart attacks, but it may occur as the first symptom of heart disease.
*Most people exhibit some symptom or discomfort.
*Symptoms usually occur during exercise or activity because the heart muscle's increased demand for nutrients and oxygen is not being met by the blocked coronary blood vessel.

Answer 5

When one or more coronary arteries narrow, it may make it difficult for adequate blood to reach the heart, especially during exercise. This can cause the heart muscle to ache like any other muscle in the body. Should the arteries continue to narrow, it may take less activity to stress the heart and provoke symptoms. The classic symptoms of chest pain and shortness of breath due to atherosclerotic or coronary artery disease are called angina.

Should one of the coronary arteries become completely blocked, usually due to a blood clot that forms, blood supply to part of the heart muscle is completely lost and that piece of muscle dies. This is called a heart attack or myocardial infarction (myo=muscle + cardia=heart + infarction= tissue death).

Answer 6

Mostly hereditary, obesity, high blood pressure, lack of exercise.

Symptoms--variable- sometimes people have none classic symptoms are atypical left sided dull aching chest pain which may radiate down left arm---which does NOT change with a deep breath--can also radiate around to back and up into the neck and jaw area.

Prevention-eating healthy, exercising,

Treatment- depends on what actually is wrong--usually a few medications- one for blood pressure, one for cholesterol, one for mucsle contractions, many different scenarios here...even open heart- with bypass or even heart transplant.

I have tried to sum up and avoid them:
Heart Disease: Risk Factors for Heart Disease

Some heart disease risk factors you can control and some you cannot. Coronary artery disease causes roughly 1.2 million heart attacks each year, and more than forty percent of those suffering from a heart attack will die. Even more worrisome, 335,000 people with heart attacks will die in an emergency department or before ever reaching the hospital. According to the American Heart Association, over 7 million Americans have suffered a heart attack in their lifetime.
What Are the Risk Factors for Heart Disease?

There are several risk factors for heart disease; some are controllable, others are not. Uncontrollable risk factors include:

* Male sex
* Older age
* Family history of heart disease
* Post-menopausal
* Race (African Americans, American Indians, and Mexican Americans are more likely to have heart disease than Caucasians)

Still, there are many risk factors that can be controlled. By making changes in your lifestyle, you can actually reduce your risk for heart disease. Controllable risk factors include:

* Smoking.
* High LDL, or "bad" cholesterol and low HDL, or "good" cholesterol.
* Uncontrolled hypertension (high blood pressure).
* Physical inactivity.
* Obesity (more than 20% over one's ideal body weight).
* Uncontrolled diabetes.
* High C-reactive protein.
* Uncontrolled stress and anger.

Symptoms are from headache to pain in chest and heart attack and death.

Answer 8

some we are born with it.other things xan be high blood preasure,diebeties,over wt high colestrol,all kinds of symtoms.depends on what type of heart disease.
dont eat high fat foods,exercise,eat heathly.different types of medications and low fat diet is the treatment .depending on what kind of heart disease you have.
