 How to prevent Aneurysm ? 
 The best way to prevent an aortic aneurysm is to avoid the factors that put you at higher risk for one. You cant control all aortic aneurysm risk factors, but lifestyle changes can help you lower some risks.
                
For example, if you smoke, try to quit. Talk with your doctor about programs and products that can help you quit smoking. Also, try to avoid secondhand smoke. For more information about how to quit smoking, go to the Diseases and Conditions Index (DCI) Smoking and Your Heart article.
                
Another important lifestyle change is following a healthy diet. A healthy diet includes a variety of fruits, vegetables, and whole grains. It also includes lean meats, poultry, fish, beans, and fat-free or low-fat milk or milk products. A healthy diet is low in saturated fat, trans fat, cholesterol, sodium (salt), and added sugar.
                
For more information about following a healthy diet, go to the National Heart, Lung, and Blood Institutes (NHLBIs) Aim for a Healthy Weight Web site, "Your Guide to a Healthy Heart," and "Your Guide to Lowering Your Blood Pressure With DASH." All of these resources include general information about healthy eating.
                
Be as physically active as you can. Talk with your doctor about the amounts and types of physical activity that are safe for you. For more information about physical activity, go to the DCI Physical Activity and Your Heart article and the NHLBIs "Your Guide to Physical Activity and Your Heart."
                
Work with your doctor to control medical conditions such as high blood pressure and high blood cholesterol. Follow your treatment plans and take all of your medicines as your doctor prescribes.
                
Screening for Aneurysms
                
Although you may not be able to prevent an aneurysm, early diagnosis and treatment can help prevent rupture and dissection.
                
Aneurysms can develop and grow large before causing any signs or symptoms. Thus, people who are at high risk for aneurysms may benefit from early, routine screening.
                
Your doctor may recommend routine screening if youre:
                
A man between the ages of 65 and 75 who has ever smoked
                
A man or woman between the ages of 65 and 75 who has a family history of aneurysms
                
If youre at risk, but not in one of these high-risk groups, ask your doctor whether screening will benefit you.

 What causes Pulmonary Hypertension ? 
 Pulmonary hypertension (PH) begins with inflammation and changes in the cells that line your pulmonary arteries. Other factors also can affect the pulmonary arteries and cause PH. For example, the condition may develop if:
                
The walls of the arteries tighten.
                
The walls of the arteries are stiff at birth or become stiff from an overgrowth of cells.
                
Blood clots form in the arteries.
                
These changes make it hard for your heart to push blood through your pulmonary arteries and into your lungs. Thus, the pressure in the arteries rises, causing PH.
                
Many factors can contribute to the process that leads to the different types of PH.
                
Group 1 pulmonary arterial hypertension (PAH) may have no known cause, or the condition may be inherited. ("Inherited" means the condition is passed from parents to children through genes.)
                
Some diseases and conditions also can cause group 1 PAH. Examples include HIV infection, congenital heart disease, and sickle cell disease. Also, the use of street drugs (such as cocaine) and certain diet medicines can lead to PAH.
                
Many diseases and conditions can cause groups 2 through 5 PH (often called secondary PH), including:
                
Mitral valve disease
                
Lung diseases, such as COPD (chronic obstructive pulmonary disease)
                
Sleep apnea
                
Sarcoidosis
                
For more information about the types of PH and the diseases, conditions, and factors that can cause them, go to "Types of Pulmonary Hypertension."
This is a medical question of type : susceptibility 
 Who is at risk for Pulmonary Hypertension? ? 
 The exact number of people who have pulmonary hypertension (PH) isn't known.
                
Group 1 pulmonary arterial hypertension (PAH) without a known cause is rare. It affects women more often than men. People who have group 1 PAH tend to be overweight.
                
PH that occurs with another disease or condition is more common.
                
PH usually develops between the ages of 20 and 60, but it can occur at any age. People who are at increased risk for PH include:
                
Those who have a family history of the condition.
                
Those who have certain diseases or conditions, such as heart and lung diseases, liver disease, HIV infection, or blood clots in the pulmonary arteries. (For more information about the diseases, conditions, and factors that cause PH, go to "Types of Pulmonary Hypertension.")
                
Those who use street drugs (such as cocaine) or certain diet medicines.
                
Those who live at high altitudes.
This is a medical question of type : symptoms 
 What are the symptoms of Pulmonary Hypertension ? 
 Signs and symptoms of pulmonary hypertension (PH) may include:
                
Shortness of breath during routine activity, such as climbing two flights of stairs
                
Tiredness
                
Chest pain
                
A racing heartbeat
                
Pain on the upper right side of the abdomen
                
Decreased appetite
                
As PH worsens, you may find it hard to do any physical activities. At this point, other signs and symptoms may include:
                
Feeling light-headed, especially during physical activity
                
Fainting at times
                
Swelling in your legs and ankles
                
A bluish color on your lips and skin

 What is (are) Deep Vein Thrombosis ? 
 Espaol
                
Deep vein thrombosis (throm-BO-sis), or DVT, is a blood clot that forms in a vein deep in the body. Blood clots occur when blood thickens and clumps together.
                
Most deep vein blood clots occur in the lower leg or thigh. They also can occur in other parts of the body.
                
A blood clot in a deep vein can break off and travel through the bloodstream. The loose clot is called an embolus (EM-bo-lus). It can travel to an artery in the lungs and block blood flow. This condition is called pulmonary embolism (PULL-mun-ary EM-bo-lizm), or PE.
                
PE is a very serious condition. It can damage the lungs and other organs in the body and cause death.
                
Blood clots in the thighs are more likely to break off and cause PE than blood clots in the lower legs or other parts of the body. Blood clots also can form in veins closer to the skin's surface. However, these clots won't break off and cause PE.

The animation shows how a blood clot in a deep vein of the leg can break off, travel to the lungs, and block blood flow.
This is a medical question of type : causes 
 What causes Deep Vein Thrombosis ? 
 Blood clots can form in your body's deep veins if:
                
A vein's inner lining is damaged. Injuries caused by physical, chemical, or biological factors can damage the veins. Such factors include surgery, serious injuries, inflammation, and immune responses.
                
Blood flow is sluggish or slow. Lack of motion can cause sluggish or slow blood flow. This may occur after surgery, if you're ill and in bed for a long time, or if you're traveling for a long time.
                
Your blood is thicker or more likely to clot than normal. Some inherited conditions (such as factor V Leiden) increase the risk of blood clotting. Hormone therapy or birth control pills also can increase the risk of clotting.
This is a medical question of type : susceptibility 
 Who is at risk for Deep Vein Thrombosis? ? 
 The risk factors for deep vein thrombosis (DVT) include:
                
A history of DVT.
                
Conditions or factors that make your blood thicker or more likely to clot than normal. Some inherited blood disorders (such as factor V Leiden) will do this. Hormone therapy or birth control pills also increase the risk of clotting.
                
Injury to a deep vein from surgery, a broken bone, or other trauma.
                
Slow blood flow in a deep vein due to lack of movement. This may occur after surgery, if you're ill and in bed for a long time, or if you're traveling for a long time.
                
Pregnancy and the first 6 weeks after giving birth.
                
Recent or ongoing treatment for cancer.
                
A central venous catheter. This is a tube placed in a vein to allow easy access to the bloodstream for medical treatment.
                
Older age. Being older than 60 is a risk factor for DVT, although DVT can occur at any age.
                
Overweight or obesity.
                
Smoking.
                
Your risk for DVT increases if you have more than one of the risk factors listed above.
This is a medical question of type : symptoms 
 What are the symptoms of Deep Vein Thrombosis ? 
 The signs and symptoms of deep vein thrombosis (DVT) might be related to DVT itself or pulmonary embolism (PE). See your doctor right away if you have signs or symptoms of either condition. Both DVT and PE can cause serious, possibly life-threatening problems if not treated.
                
Deep Vein Thrombosis
                
Only about half of the people who have DVT have signs and symptoms. These signs and symptoms occur in the leg affected by the deep vein clot. They include:
                
Swelling of the leg or along a vein in the leg
                
Pain or tenderness in the leg, which you may feel only when standing or walking
                
Increased warmth in the area of the leg that's swollen or painful
                
Red or discolored skin on the leg
                
Pulmonary Embolism
                
Some people aren't aware of a deep vein clot until they have signs and symptoms of PE. Signs and symptoms of PE include:
                
Unexplained shortness of breath
                
Pain with deep breathing
                
Coughing up blood
                
Rapid breathing and a fast heart rate also may be signs of PE.
This is a medical question of type : exams and tests 
 How to diagnose Deep Vein Thrombosis ? 
 Your doctor will diagnose deep vein thrombosis (DVT) based on your medical history, a physical exam, and test results. He or she will identify your risk factors and rule out other causes of your symptoms.
                
For some people, DVT might not be diagnosed until after they receive emergency treatment for pulmonary embolism (PE).
                
Medical History
                
To learn about your medical history, your doctor may ask about:
                
Your overall health
                
Any prescription medicines you're taking
                
Any recent surgeries or injuries you've had
                
Whether you've been treated for cancer
                
Physical Exam
                
Your doctor will check your legs for signs of DVT, such as swelling or redness. He or she also will check your blood pressure and your heart and lungs.
                
Diagnostic Tests
                
Your doctor may recommend tests to find out whether you have DVT.
                
Common Tests
                
The most common test for diagnosing deep vein blood clots is ultrasound. This test uses sound waves to create pictures of blood flowing through the arteries and veins in the affected leg.
                
Your doctor also may recommend a D-dimer test or venography (ve-NOG-rah-fee).
                
A D-dimer test measures a substance in the blood that's released when a blood clot dissolves. If the test shows high levels of the substance, you may have a deep vein blood clot. If your test results are normal and you have few risk factors, DVT isn't likely.
                
Your doctor may suggest venography if an ultrasound doesn't provide a clear diagnosis. For venography, dye is injected into a vein in the affected leg. The dye makes the vein visible on an x-ray image. The x ray will show whether blood flow is slow in the vein, which may suggest a blood clot.
                
Other Tests
                
Other tests used to diagnose DVT include magnetic resonance imaging (MRI) and computed tomography (to-MOG-rah-fee), or CT, scanning. These tests create pictures of your organs and tissues.
                
You may need blood tests to check whether you have an inherited blood clotting disorder that can cause DVT. This may be the case if you have repeated blood clots that are not related to another cause. Blood clots in an unusual location (such as the liver, kidney, or brain) also may suggest an inherited clotting disorder.
                
If your doctor thinks that you have PE, he or she may recommend more tests, such as a lung ventilation perfusion scan (VQ scan). A lung VQ scan shows how well oxygen and blood are flowing to all areas of the lungs.
                
For more information about diagnosing PE, go to the Health Topics Pulmonary Embolism article.
This is a medical question of type : prevention 
 How to prevent Deep Vein Thrombosis ? 
 You can take steps to prevent deep vein thrombosis (DVT) and pulmonary embolism (PE). If you're at risk for these conditions:
                
See your doctor for regular checkups.
                
Take all medicines as your doctor prescribes.
                
Get out of bed and move around as soon as possible after surgery or illness (as your doctor recommends). Moving around lowers your chance of developing a blood clot.
                
Exercise your lower leg muscles during long trips. This helps prevent blood clots from forming.
                
If you've had DVT or PE before, you can help prevent future blood clots. Follow the steps above and:
                
Take all medicines that your doctor prescribes to prevent or treat blood clots
                
Follow up with your doctor for tests and treatment
                
Use compression stockings as your doctor directs to prevent leg swelling
                
Contact your doctor at once if you have any signs or symptoms of DVT or PE. For more information, go to "What Are the Signs and Symptoms of Deep Vein Thrombosis?"
                
Travel Tips
                
The risk of developing DVT while traveling is low. The risk increases if the travel time is longer than 4 hours or you have other DVT risk factors.
                
During long trips, it may help to:
                
Walk up and down the aisles of the bus, train, or airplane. If traveling by car, stop about every hour and walk around.
                
Move your legs and flex and stretch your feet to improve blood flow in your calves.
                
Wear loose and comfortable clothing.
                
Drink plenty of fluids and avoid alcohol.
                
If you have risk factors for DVT, your doctor may advise you to wear compression stockings while traveling. Or, he or she may suggest that you take a blood-thinning medicine before traveling.

 What is (are) Heart Palpitations ? 
 Palpitations (pal-pi-TA-shuns) are feelings that your heart is skipping a beat, fluttering, or beating too hard or too fast. You may have these feelings in your chest, throat, or neck. They can occur during activity or even when you're sitting still or lying down.
                
Overview
                
Many things can trigger palpitations, including:
                
Strong emotions
                
Vigorous physical activity
                
Medicines such as diet pills and decongestants
                
Caffeine, alcohol, nicotine, and illegal drugs
                
Certain medical conditions, such as thyroid disease or anemia (uh-NEE-me-uh)
                
These factors can make the heart beat faster or stronger than usual, or they can cause premature (extra) heartbeats. In these situations, the heart is still working normally. Thus, these palpitations usually are harmless.
                
Some palpitations are symptoms of arrhythmias (ah-RITH-me-ahs). Arrhythmias are problems with the rate or rhythm of the heartbeat.
                
Some arrhythmias are signs of heart conditions, such as heart attack, heart failure, heart valve disease, or heart muscle disease. However, less than half of the people who have palpitations have arrhythmias.
                
You can take steps to reduce or prevent palpitations. Try to avoid things that trigger them (such as stress and stimulants) and treat related medical conditions.
                
Outlook
                
Palpitations are very common. They usually aren't serious or harmful, but they can be bothersome. If you have them, your doctor can decide whether you need treatment or ongoing care.
This is a medical question of type : susceptibility 
 Who is at risk for Heart Palpitations? ? 
 Some people may be more likely than others to have palpitations. People at increased risk include those who:
                
Have anxiety or panic attacks, or people who are highly stressed
                
Take certain medicines or stimulants
                
Have certain medical conditions that aren't related to heart problems, such as an overactive thyroid
                
Have certain heart problems, such as arrhythmias (irregular heartbeats), a previous heart attack, heart failure, heart valve disease, or heart muscle disease
                
Women who are pregnant, menstruating, or perimenopausal also may be at higher risk for palpitations because of hormonal changes. Some palpitations that occur during pregnancy may be due to anemia.
                
For more information about these risk factors, go to "What Causes Palpitations?"
This is a medical question of type : symptoms 
 What are the symptoms of Heart Palpitations ? 
 Symptoms of palpitations include feelings that your heart is:
                
Skipping a beat
                
Fluttering
                
Beating too hard or too fast
                
You may have these feelings in your chest, throat, or neck. They can occur during activity or even when you're sitting still or lying down.
                
Palpitations often are harmless, and your heart is working normally. However, these feelings can be a sign of a more serious problem if you also:
                
Feel dizzy or confused
                
Are light-headed, think you may faint, or do faint
                
Have trouble breathing
                
Have pain, pressure, or tightness in your chest, jaw, or arms
                
Feel short of breath
                
Have unusual sweating
                
Your doctor may have already told you that your palpitations are harmless. Even so, see your doctor again if your palpitations:
                
Start to occur more often or are more noticeable or bothersome
                
Occur with other symptoms, such as those listed above
                
Your doctor will want to check whether your palpitations are the symptom of a heart problem, such as an arrhythmia (irregular heartbeat).
This is a medical question of type : treatment 
 What are the treatments for Heart Palpitations ? 
 Treatment for palpitations depends on their cause. Most palpitations are harmless and often go away on their own. In these cases, no treatment is needed.
                
Avoiding Triggers
                
Your palpitations may be harmless but bothersome. If so, your doctor may suggest avoiding things that trigger them. For examples, your doctor may advise you to:
                
Reduce anxiety and stress. Anxiety and stress (including panic attacks) are a common cause of harmless palpitations. Relaxation exercises, yoga or tai chi, biofeedback or guided imagery, or aromatherapy may help you relax.
                
Avoid or limit stimulants, such as caffeine, nicotine, or alcohol.
                
Avoid illegal drugs, such as cocaine and amphetamines.
                
Avoid medicines that act as stimulants, such as cough and cold medicines and some herbal and nutritional supplements.
                
Treating Medical Conditions That May Cause Palpitations
                
Work with your doctor to control medical conditions that can cause palpitations, such as an overactive thyroid. If you're taking medicine that's causing palpitations, your doctor will try to find a different medicine for you.
                
If your palpitations are caused by an arrhythmia (irregular heartbeat), your doctor may recommend medicines or procedures to treat the problem. For more information, go to the Health Topics Arrhythmia article.
