• Patient History • – a written history of an illness that includes all the

facts of medical significance in the life of the patient.

• Chief complaint • - a concise statement describing the symptom,

problem, condition, diagnosis, physician recommended return, or other factor that is the reason for a medical encounter

• Diagnosis• the determination of the nature of a case of a disease

or the distinguishing of one disease from another

• Symptom• any subjective evidence of disease or of a patient's

condition.

• Sign• any objective evidence of a disease, i.e., such evidence

as is perceptible to the examining physician

• Prognosis• prediction of the probable course and outcome of a

disease.

• Differential diagnosis• The process of weighing the probability of one disease

versus that of other diseases possibly accounting for a patient's illness

• Acute• Of or relating to a disease or a condition with a rapid

onset and a short, severe course

• Chronic• Of long duration. Used of a disease of slow progress

and long continuance.

• Acute abdomen– Medical shorthand for the acute onset of

abdominal pain– potential medical emergency– may reflect a major problem with one of the

organs in the abdomen, such as appendicitis(inflamed appendix), cholecystitis (inflamed gallbladder), a perforated ulcer in the intestine, or a ruptured spleen.

• Acute coronary syndromes– spectrum of conditions involving chest discomfort or

other symptoms caused by lack of oxygen to the heart muscle

– most common symptom prompting diagnosis of ACS is chest pain, often radiating of the left arm or angle of the jaw, pressure-like in character, and associated with nausea and sweating

– usually occurs as a result of one of three problems: ST elevation myocardial infarction (30%), non ST elevation myocardial infarction (25%), or unstable angina (38%)

• Adenitis – is a general term for an inflammation of

a gland or lymph node usually caused by bacterial infections

– swelling of lymph nodes due to growth of lymph cells is called lymphadenopathy

– E.g.: cervical adenitis, mesenteric adenitis

disease, the factors which produce or predispose toward a certain disease or disorder

to the heart muscle– The pain is typically severe and crushing, and it is

characterized by a feeling of pressure and suffocation just behind the breastbone

– can accompany or be a precursor of a heart attack

• Prinzmetal angina– Chest pain due to a coronary artery spasm, a

sudden constriction of one of the vessels that supply the heart muscle with blood rich in oxygen

– can be triggered by emotional stress, medicines, street drugs (cocaine) or exposure to cold

– Usually treated with beta-blocker medications and nitroglycerin to open up the coronary arteries.

• Angiogram– An X-ray image of blood vessels– The vessels can be seen because a contrast dye

within them blocks the X-rays from developing an imaging film.

reduce inflammation during the first weeks of illness• The outlook is generally good; the vast majority of patients

recover within weeks or months.
