In caring for patients with chest pain, the doctor
distinguishes whether
the pain is related to a lack of oxygen to the heart muscle (as
in angina
or heart attack), or is due to another process. Many conditions
are
considered that can cause chest pain which is similar to that
of a heart
attack or angina. Examples include the following:
Pleuritis (pleurisy): Inflammation of the lining of the lungs (pleuritis) causes sharp chest pain, which is aggravated by deep breathing and
coughing. Patients often notice shortness of breath, in part due to their shallow breathing to minimize chest pain. Viral infections are the most common causes of pleurisy. Other systemic inflammatory conditions, such as
systemic lupus, can also cause pleurisy.
Pericarditis:Pericarditis is inflammation of the lining around the heart. Symptoms of pericarditis are similar to that of pleuritis.
Pneumonia: Pneumonia (bacterial infection of the lung) causes fever and chest pain. Chest pain in bacterial pneumonia is due to an irritation or infection of the lining of the lung (pleura).
Pulmonary embolism:blood clots travel from the veins of the pelvis or the lower extremities to the lung, the condition is called
pulmonary embolism. Pulmonary embolism can cause death of lung tissue (pulmonary infarction). Pulmonary infarction can lead to irritation of the pleura, causing chest pain similar to pleurisy. Some common causes of blood clots in these veins
is deep vein thrombosis
(prolonged immobility, recent surgery, trauma to the legs, or pelvic infection).
Pneumothorax: Small sacs in the lung tissue (alveoli) can spontaneously burst, causing
pneumothorax. Symptoms of pneumothorax include sudden, severe, sharp chest pain and shortness of breath. One common cause of pneumothorax is severe emphysema.
Mitral valve prolapse:Mitral valve prolapse is a common heart valve abnormality, affecting 5%
to 10% of the population. MVP is especially common among women between 20 to 40 years of age. Chest pain with MVP is usually sharp
but not severe. Unlike angina, chest pain with MVP rarely occurs during or after exercise, and usually will not respond to nitroglycerin.
Aortic dissection:
The aorta is the major vessel delivering blood from the left ventricle to the rest of the body.
Aortic dissection (tearing of the aorta wall) is a life-threatening emergency. Aortic dissection causes severe, unrelenting chest and back pain. Young adults with aortic dissection usually have
Marfan's syndrome, an inherited disease in which an abnormal form of the structural protein called collagen causes weakness of the aortic wall. Older patients develop aortic dissection typically as a result of chronic, high blood pressure, in addition to generalized hardening of the arteries (arteriosclerosis).
Costochondritis, rib fractures, muscle strain or spasm:
Pain originating from the chest wall may be due to
muscle strain or
spasm,
costochondritis, or
rib fractures. Chest wall pain is usually sharp and constant. It is usually worsened by movement, coughing, deep breathing, and direct pressure on the area. Muscle spasm and strain can result from vigorous, unusual twisting and bending. The joints between the ribs and cartilage next to the breastbone can become inflamed, a condition called costochondritis. Fractured ribs resulting from trauma or cancer involvement can cause significant chest pain.
Nerve compression:Compression of the nerve
roots by bone spurs as they exit the spinal cord can cause pain.
Nerve compression can also cause weakness and numbness in the upper arm
and chest.
Shingles (herpes zoster infection of the nerves):Shingles is nerve
irritation from the infection, which can cause chest pain days before
any typical rash appears.
Esophageal spasm and reflux:
The esophagus is the long muscular tube connecting the mouth to the stomach.
Reflux, or regurgitation of stomach contents and acid into the esophagus can cause heartburn and chest pain. Spasm of the muscle of the esophagus can also cause chest pain which can be indistinguishable from chest pain caused by angina or a heart attack. The cause of esophageal muscle spasm is not known. Pain of esophageal spasm can respond to nitroglycerin in a similar manner as angina.
Gallbladder attack (gallstones): Gallstones can block the gallbladder or bile ducts and cause severe pain of the upper abdomen, back and chest. Gallbladder attacks can mimic the pain of angina and heart attack.
Anxiety and panic attacks: Anxiety, depression, and
panic attacks are frequently associated with chest pain
lasting from minutes to days. The pain can be sharp or dull. It is usually
accompanied by shortness of breath, or the inability to take a deep breath.
Emotional stress can aggravate chest pain, but the pain is generally not related
to exertion, and is not relieved by nitroglycerin. These patients often breath
too fast (hyperventilate), causing lightheadedness, numbness, and tingling in the lips and fingers.
Coronary artery disease risk factors are typically absent in these patients. Since there is no test for panic attacks, patients with chest pain usually undergo tests to exclude coronary artery disease and other causes of chest pain.
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, or even 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.
Dizziness is a symptom that is often applies to a variety of sensations including lightheadedness and vertigo. Causes of dizziness include low blood pressure, heart problems, anemia, dehydration, and more. Treatment of dizziness depends on the cause.
Cholesterol is naturally produced by the body, and is a building block for cell membranes and hormones. Low-density lipoprotein (LDL) cholesterol is the "bad" cholesterol, conversely, high-density lipoprotein (HDL) cholesterol is the "good" cholesterol. High cholesterol treatment includes lifestyle changes (diet and exercise), and medications such as statins, bile acid resins, and fibric acid derivatives.
Heart attack happens when a blood clot completely obstructs a coronary
artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical
instability of the heart.
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.
Toothache usually refers to pain around the teeth or jaws. In most instances, toothaches are caused by tooth or jaw problems, such as a dental cavity, a cracked tooth, an exposed tooth root, gum disease, disease of the jaw joint (TMJ), or spasms of the muscles used for chewing. A toothache can also be caused by a problem that does not originate from a tooth or the jaw, like diseases of the heart (angina or heart attack), ear infections, and sinus infections. A thorough oral examination, which includes dental X-rays, can help determine the cause.
Insulin resistance is the diminished ability of cells to respond to the action of insulin in transporting glucose (sugar) from the bloodstream into muscle and other tissues. Causes of insulin can include conditions such as stress, obesity, metabolic syndrome, and steroid use. Some of the risk factors for insulin resistance include fatty liver, heart disease, strokes, peripheral vascular disease, high cholesterol, and smoking. Treatment for insulin resistance are lifestyle changes and if necessary, medication.
Aortic valve stenosis is an abnormal narrowing of the aortic valve of the heart. The causes of aortic stenosis are wear and tear of the valve in the elderly, congenital, or scarring or scarring of the aortic valve from rheumatic fever. Symptoms include angina, fainting, and shortness of breath. Treatment is dependant upon the severity of the condition.
Heart disease (coronary artery disease) is caused by a buildup of cholesterol deposits in the coronary arteries. Risk factors for heart disease include smoking, high blood pressure, heredity, diabetes, peripheral artery disease, and obesity. Symptoms include chest pain and shortness of breath. There are a variety of tests used to diagnose coronary artery disease. Treatment includes life-style changes, medications, procedures, or surgery.
Pulmonary hypertension is an abnormal elevation of the pressure in the pulmonary circulation caused by the constriction of the blood vessels that supply blood to the lungs. Shortness of breath and dizziness are symptoms of pulmonary hypertension. Treatment involves diuretics, blood thinners, calcium channel blockers, and using supplemental oxygen to increase blood oxygen levels.
Pericarditis is the inflammation of the pericardial sac that surrounds the heart. The causes of pericarditis include injury from heart attack, heart surgery, trauma; viral or fungal infection, HIV, tumors, mixed connective tissue disease, metabolic disease, medication reactions, or idiopathic. Treatment for pericarditis is generally medication, however, sometimes surgery is necessary.
The connection between stress and heart disease is not clear. Stress itself may be a risk factor, or high levels of stress may make risk factors for heart disease worse. The warning signs of stress can be physical, mental, emotional, or behavioral. Reducing stressors in an individuals life not only can lead to a more productive life, but may also decrease the risk for heart disease and causes of heart disease.
Cholesterol is the most common type of steroid in the body. The treatment of elevated cholesterol involves not only diet but also weight loss, regular exercise, and medications. By understanding your cholesterol profile you can better manage your cholesterol levels.
Heart disease, particularly coronary artery disease is the leading cause of heart attacks. Women are more likely to die from a heart attack than men. High cholesterol, high blood pressure, obesity, and high triglycerides are contributors to heart disease. Some of the common symptoms of a heart attack in women include chest pain, shortness of breath, nausea, feeling faint or woozy, and more. Heart disease can be prevented by lifestyle changes and controlling high blood pressure, cholesterol, weight, and diseases such as diabetes.
Heart attacks are the major causes of unexpected, sudden death among men and women. A heart attack is also a significant cause of heart failure. Learn the risk factors for heart attack such as high blood pressure, diabetes, and other heart conditions. Lowering your risk factor, lifestyle changes, and in some cases medication are the most effective way of preventing a heart attack.
Biologic rhythms, or biorhythms, are how our bodies respond to the regular phases of the sun, moon, and seasons. A medical chronobiologist studies how the "body clock" or biorhythms affect diseases and how the body clock responds to treatment of diseases and conditions at different times of the day.
Hypertrophic cardiomyopathy (HCM) affects many people today. Many people with HCM have no symptoms or only minor symptoms, and live a normal life. Other people develop symptoms, which progress and worsen as heart function worsens.
Cholesterol occurs naturally in the body. High blood cholesterol levels increase a person's risk of developing heart disease, heart attacks, strokes, TIAs, and more. In addition to medication (fibrates, statins, bile acid sequestrants, and niacin), lifestyle changes can be made to lower blood cholesterol levels
Vitamins and exercise can lower your risk for heart attack and heart disease. Folic acid, vitamins, and homocysteine levels are interconnected and affect your risk for heart disease or heart attack. Antioxidants and exercise also play a key role in heart attack and heart disease prevention. Lower your risk factors for heart disease and heart attack by lowering cholesterol, lowering blood pressure, diabetes prevention, and smoking cesssation.
