Angina is chest pain due to inadequate blood supply to the heart. Angina symptoms may include chest tightness, burning, squeezing, and aching. Coronary artery disease is the main cause of angina but there are other causes. Angina is diagnosed by taking the patient's medical history and performing tests such as an electrocardiogram (EKG), blood test, stress test, echocardiogram, cardiac CT scan, and heart catheterization. Treatment of angina usually includes lifestyle modification, medication, and sometimes, surgery. The risk of angina can be reduced by following a heart healthy lifestyle.
Antiphospholipid syndrome (phospholipid antibody syndrome or Hughes syndrome) is an immune system disorder with symptoms that include: excessive blood clotting, miscarriages unexplained fetal death, or premature birth. In antiphospholipid syndrome, these symptoms are accompanied by the presence of antiphospholipid antibodies (cardiolipin or lupus anticoagulant antibodies) in the blood. Treatment focuses on preventing clotting by thinning the blood with the use of anticoagulants and aspirin.
A stroke is an interruption of the blood supply to part of the brain caused by either a blood clot (ischemic) or bleeding (hemorrhagic). Symptoms of a stroke may include: weakness, numbness, double vision or vision loss, confusion, vertigo, difficulty speaking or understanding speech. A physical exam, imaging tests, neurological exam, and blood tests may be used to diagnose a stroke. Treatment may include administration of clot-busting drugs, supportive care, and in some instances, neurosurgery. The risk of stroke can be reduced by controlling high blood pressure, high cholesterol, diabetes, and stopping smoking.
Varicose vein: A dilated (widened) tortuous (twisting) vein, usually involving a superficial vein in the leg, often associated with incompetency of the valves in the vein. These visible and bulging veins are often associated with symptoms such as tired, heavy, or aching limbs. Spider veins are a group of widened veins that can be seen through the surface of the skin.
Obesity is the state of being well above one's normal weight. A person has traditionally been considered to be obese if they are more than 20% over their ideal weight. That ideal weight must take into account the person's height, age, sex, and build.
Low Blood Pressure (Hypotension)
Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, and fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
Intermittent claudication, or pain and cramping in the lower leg is caused by inadequate blood flow to the leg muscles. This lack of blood flow causes a decrease in oxygen delivered to the muscles of the legs. Claudication is generally felt when walking and decreases with rest. In severe cases, claudication may be felt at rest. Narrowing of arteries cause claudication. Treatment includes exercise, medication, and in some cases surgery.
Jet lag (desynchonosis) is a temporary disorder that results from travel across time zones. Symptoms include anxiety, constipation, headache, nausea, dehydration, diarrhea, confusion, sweating, irritability, and even memory loss.
Smoking (How to Quit Smoking)
Smoking is an addiction. More than 430,000 deaths occur each year in the U.S. from smoking related illnesses. Secondhand smoke or "passive smoke" also harm family members, coworkers, and others around smokers. There are a number of techniques available to assist people who want to quit smoking.
Edema is the swelling of tissues as a result of excess water accumulation. Peripheral edema occurs in the feet and legs. There are two types of edema, non-pitting edema and pitting edema. Causes of pitting edema is caused by systemic diseases (most commonly involving the heart, liver, and kidneys), and medications. Local conditions that cause edema are thrombophlebitis and varicose veins. Edema or swelling of the legs, feet, ankles, and face are common during pregnancy. Idiopathic edema is edema in which the cause is not known. Pitting edema is scored on pitting edema measurement scales. Edema is generally treated with medication.

Genetic Diseases (Disorder Definition, Types, and Examples)
The definition of a genetic disease is a disorder or condition caused by abnormalities in a person's genome. Some types of genetic inheritance include single inheritance, including cystic fibrosis, sickle cell anemia, Marfan syndrome, and hemochromatosis. Other types of genetic diseases include multifactorial inheritance. Still other types of genetic diseases include chromosome abnormalities (for example, Turner syndrome, and Klinefelter syndrome), and mitochondrial inheritance (for example, epilepsy and dementia).
Breast Cancer and Lymphedema
Lymphedema is a common chronic, debilitating condition in which excess fluid called lymph collects in tissues and causes swelling in them. It is common after a mastectomy, lumpectomy or breast cancer surgery and radiation therapy.
Sudden Cardiac Arrest
Sudden cardiac arrest is an unexpected, sudden death caused by sudden cardiac arrest (loss of heart function). Causes and risk factors of sudden cardiac arrest include (not inclusive): abnormal heart rhythms (arrhythmias), previous heart attack, coronary artery disease, smoking, high cholesterol, Wolff-Parkinson-White Syndrome, ventricular tachycardia or ventricular fibrillation after a heart attack, congenital heart defects, history of fainting, heart failure, obesity, diabetes, and drug abuse. Treatment of sudden cardiac arrest is an emergency, and action must be taken immediately.

The symptoms and signs of serious health problems can be caused by strokes, heart attacks, cancers, reproductive problems in females (for example, cancers, fibroids, endometriosis, ovarian cysts, and sexually transmitted diseases or STDs), breast problems (for example, breast cancer and non-cancer related diseases), lung diseases (for example, chronic obstructive pulmonary disease or COPD, lung cancer, emphysema, and asthma), stomach or digestive diseases (for example, cancers, gallbladder, liver, and pancreatic diseases, ulcerative colitis, or Crohn's disease), bladder problems (for example, urinary incontinence, and kidney infections), skin cancer, muscle and joint problems, emotional problems or mental illness (for example, postpartum depression, major depression, post-traumatic stress disorder (PTSD), mania, and schizophrenia), and headache disorders (for example, migraines, or "the worst headache of your life), and eating disorders and weight problems (for example, anorexia or bulimia).
ARDS (Acute Respiratory Distress Syndrome)
Acute respiratory distress syndrome (ARDS) is a lung condition in which trauma to the lungs leads to inflammation of the lungs, accumulation of fluid in the alveolar air sacs, low blood oxygen, and respiratory distress. ARDS can be life-threatening. Signs and symptoms of are shortness of breath and low levels of oxygen in the blood, which can cause your organs to fail. Causes of ARDS include: Pneumonia Aspiration into the lungs Severe blow to the chest Sepsis Severe injury with shock Drug overdose Inflamed pancreas Other lung conditions and infections Burns Sepsis Near drowning Fractures There have been genetic factors linked to ARDS. Treatment for includes supplemental oxygen, and/or medication. According to some studies, survival rates for ARDS depend upon the cause associated with it, but can vary from 48% to 68%.REFERENCES: Harman, EM, MD.

Chest pain is a common complaint by a patient in the ER. Causes of chest pain include broken or bruised ribs, pleurisy, pneumothorax, shingles, pneumonia, pulmonary embolism, angina, heart attack, costochondritis, pericarditis, aorta or aortic dissection, and reflux esophagitis. Diagnosis and treatment of chest pain depends upon the cause and clinical presentation of the patient's chest pain.
Pulmonary Embolism (Blood Clot in the Lung)
A pulmonary embolism (PE) occurs when a piece of a blood clot from deep vein thrombosis (DVT) breaks off and travels to an artery in the lung where it blocks the artery and damages the lung. The most common symptoms of a pulmonary embolism are shortness of breath, chest pain, and a rapid heart rate. Causes of pulmonary embolism include prolonged immobilization, certain medications, smoking, cancer, pregnancy, and surgery. Pulmonary embolism can cause death if not treated promptly.
Blood Clots (in the Leg)
Blood clots can occur in the venous and arterial vascular system. Blood clots can form in the heart, legs, arteries, veins, bladder, urinary tract and uterus. Risk factors for causes of blood clots include high blood pressure and cholesterol, diabetes, smoking, and family history. Symptoms of a blood clot depend on the location of the clot. Some blood clots are a medical emergency. Blood clots are treated depending upon the cause of the clot. Blood clots can be prevented by lowering the risk factors for developing blood clots.
Phlebitis is the inflammation of a vein. Thrombophlebitis is when a blood clot causes the inflammation. Phlebitis can be superficial or deeper in the veins. A blood clot deep in a vein is deep vein thrombosis (DVT). Some of the common causes of phlebitis include prolonged inactivity, varicose veins, trauma to a vein, underlying cancers, clotting disorders, and other causes. Symptoms of phlebitis may be mild (pain, tenderness, redness, or bulging of a vein. Treatment of phlebitis depends on the cause.
High Red Blood Cell Count (Polycythemia)
Polycythemia (elevated red blood cell count) is a rare blood disease in which the body produces too many red blood cells. Causes of polycythemia are either primary (acquired or genetic mutations) or secondary (diseases, conditions, high altitude).
Enlarged Spleen (Splenomegaly) Symptoms, Signs, Causes,Treatment
An enlarged spleen or splenomegaly, is generally caused by other diseases or conditions such as infections, cancers, blood disorders, or decreased blood flow. Symptoms of an enlarged spleen are often unnoticed. A feeling of fullness after eating a small amount of food and not being able to eat large meals may be a symptom of an enlarged spleen. Treatment for an enlarged spleen depends upon the cause.
Lymphedema is a condition in which one or more extremities become swollen as the result of an impaired flow of the lymphatic system. There are two types of lymphedema: primary and secondary. Filariasis is the most common cause of lymphedema worldwide. In the U.S., breast cancer surgery is the most common cause. Symptoms include swelling of one or more limbs, cracked and thickening skin, and secondary bacterial or fungal infections of the skin. There is no cure for lymphedema.
Scalp Psoriasis (Psoriasis of the Scalp)
Scalp psoriasis causes red, raised, scaly patches that may extend from the scalp to the forehead and the back of the neck and ears. Symptoms and signs include itching, hair loss, flaking, silvery scales, and red plaques. Treatment includes topical medicated shampoos, creams, gels, oils, ointments, and soaps, medications, and light therapy.

Atrial Flutter (Symptoms, Causes, ECG, and Treatments)
Atrial flutter is a problem with the atria of the heart. In atrial flutter the atria of the heart rapidly and repeatedly beat due to an anomaly in the electrical system of the heart. It is a type of arrhythmia and can be dangerous because complications can develop easily. Signs and symptoms of atrial flutter include near fainting, palpitations, mild shortness of breath, and fatigue. While the exact cause of atrial flutter is not clearly understood, it's most likely related to your health, what medical conditions you certainly have, poor diet, lack of exercise, and drinking too much alcohol. Atrial flutter is diagnosed by physical examination, medical history, and a sawtooth ECG wave pattern.
DVT and Birth Control Pills (Oral Contraceptives)
Deep vein thrombosis (DVT) is a blood clot that has traveled deep into the veins of the arm, pelvis, or lower extremities. Oral contraceptives or birth control pills can slightly increase a woman’s risk for developing blood clots, including DVT. DVT symptoms and signs in the leg include leg or calf pain, redness, swelling, warmth, or leg cramps, and skin discoloration. If a blood clot in the leg is not treated, it can travel to the lungs, which can cause a pulmonary embolism (blood clot in the lung) or post-thrombotic syndrome, both of which can be fatal if not treated immediately. Increased risk factors for DVT and birth control pills include over 40 years of age, family history, smoking, and obesity. Other medical problems that increase the risks of blood clots, for example, lung or heart disease, or inflammatory bowel disease or IBD (Crohn’s disease and ulcerative colitis (UC). Other options for preventing pregnancy include IUDs, birth control shots, condoms, diaphragms, and progestin-only oral contraceptives.
DVT (Deep Vein Thrombosis) During Pregnancy
Deep vein thrombosis or DVT is a condition in which a blood clot becomes embedded in one of the deep veins of the arms, thighs, pelvis, or lower legs. Warning signs and symptoms of DVT include pain, warmth, redness, swelling, leg cramps, and worsening leg pain in the affected extremity. Many conditions and other factors can cause DVTs, for example, during pregnancy including postpartum (6-8 weeks after delivery of the baby), obesity, heart attacks or heart failure, cancer, birth control pills (oral contraceptives), recent surgery, high altitudes, and advanced age. Treatment guidelines for DVT diagnosed during pregnancy is anticoagulation (anti-clotting) drugs, usually, low-molecular-weight heparins. DVT treatment may need to be continued postpartum. Warfarin (Coumadin, Jantoven) should not be used to treat DVT during pregnancy because it can harm the developing fetus.
