The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats.

Information for Patients
Health Problems in Pregnancy
Every pregnancy has some risk of problems. You may have problems because of a health condition you had before you got pregnant. You could also develop a condition during pregnancy. Other causes of problems during pregnancy can include being pregnant with more than one baby, a health problem in a previous pregnancy, substance abuse during pregnancy, or being over age 35. Any of these can affect your health, the health of your baby, or both.
If you have a chronic condition, you should talk to your health care provider about how to minimize your risk before you get pregnant. Once you are pregnant, you may need a health care team to monitor your pregnancy. Some common conditions that can complicate a pregnancy include
- High blood pressure
- Polycystic ovary syndrome
- Kidney problems
- Autoimmune disorders
- Obesity
- HIV/AIDS
- Cancer
- Infections
Other conditions that can make pregnancy risky can happen while you are pregnant - for example, gestational diabetes and Rh incompatibility. Good prenatal care can help detect and treat them.
Some discomforts, like nausea, back pain, and fatigue, are common during pregnancy. Sometimes it is hard to know what is normal. Call your health care provider if something is bothering or worrying you.

Heart Diseases
Also called: Cardiac diseases
If you're like most people, you think that heart disease is a problem for others. But heart disease is the number one killer in the U.S. It is also a major cause of disability. There are many different forms of heart disease. The most common cause of heart disease is narrowing or blockage of the coronary arteries, the blood vessels that supply blood to the heart itself. This is called coronary artery disease and happens slowly over time. It's the major reason people have heart attacks.
Other kinds of heart problems may happen to the valves in the heart, or the heart may not pump well and cause heart failure. Some people are born with heart disease.
You can help reduce your risk of heart disease by taking steps to control factors that put you at greater risk:
- Control your blood pressure
- Lower your cholesterol
- Don't smoke
- Get enough exercise

Vascular Diseases
What are vascular diseases?
Your vascular system is your body's network of blood vessels. It includes your
- Arteries, which carry oxygen-rich blood from your heart to your tissues and organs
- Veins, which carry the blood and waste products back to your heart
- Capillaries, which are tiny blood vessels that connect your small arteries to your small veins. The walls of the capillaries are thin and leaky, to allow for an exchange of materials between your tissues and blood.
Vascular diseases are conditions which affect your vascular system. They are common and can be serious. Some types include
- Aneurysm - a bulge or "ballooning" in the wall of an artery
- Atherosclerosis - a disease in which plaque builds up inside your arteries. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood.
- Blood clots, including deep vein thrombosis and pulmonary embolism
- Coronary artery disease and carotid artery disease, diseases that involve the narrowing or blockage of an artery. The cause is usually a buildup of plaque.
- Raynaud's disease - a disorder that causes the blood vessels to narrow when you are cold or feeling stressed
- Stroke - a serious condition that happens when blood flow to your brain stops.
- Varicose veins - swollen, twisted veins that you can see just under the skin
- Vasculitis - inflammation of the blood vessels
What causes vascular diseases?
The causes of vascular diseases depend on the specific disease. These causes include
- Genetics
- Heart diseases such as high cholesterol and high blood pressure
- Infection
- Injury
- Medicines, including hormones
Sometimes the cause is unknown.
Who is at risk for vascular diseases?
The risk factors for vascular diseases can vary, depending on the specific disease. But some of the more common risk factors include
- Age - your risk of some diseases goes up as you get older
- Conditions that can affect the heart and blood vessels, such as diabetes or high cholesterol
- Family history of vascular or heart diseases
- Infection or injury that damages your veins
- Lack of exercise
- Obesity
- Pregnancy
- Sitting or standing still for long periods of time
- Smoking
What are the symptoms of vascular diseases?
The symptoms for each disease are different.
How are vascular diseases diagnosed?
To make a diagnosis, your health care provider will do a physical exam and ask about your symptoms and medical history. You may have imaging tests and/or blood tests.
How are vascular diseases treated?
Which treatment you get depends on which vascular disease you have and how severe it is. Types of treatments for vascular diseases include
- Lifestyle changes, such as eating a heart-healthy diet and getting more exercise
- Medicines, such as blood pressure medicines, blood thinners, cholesterol medicines, and clot-dissolving drugs. In some cases, providers use a catheter to send medicine directly to a blood vessel.
- Non-surgical procedures, such as angioplasty, stenting, and vein ablation
- Surgery
Can vascular diseases be prevented?
There are steps you can take to help prevent vascular diseases:
- Make healthy lifestyle changes, such as eating a heart-healthy diet and getting more exercise
- Don't smoke. If you are already a smoker, talk to your health care provider for help in finding the best way for you to quit.
- Keep your blood pressure and cholesterol in check
- If you have diabetes, control your blood sugar
- Try not to sit or stand for up long periods of time. If you do need to sit all day, get up and move around every hour or so. If you traveling on a long trip, you can also wear compression stockings and regularly stretch your legs.
