MedicalCause

Defined in the health-lifesci.schema.org extension.
Canonical URL: http://schema.org/MedicalCause

Thing > MedicalEntity > MedicalCause

The causative agent(s) that are responsible for the pathophysiologic process that eventually results in a medical condition, symptom or sign. In this schema, unless otherwise specified this is meant to be the proximate cause of the medical condition, symptom or sign. The proximate cause is defined as the causative agent that most directly results in the medical condition, symptom or sign. For example, the HIV virus could be considered a cause of AIDS. Or in a diagnostic context, if a patient fell and sustained a hip fracture and two days later sustained a pulmonary embolism which eventuated in a cardiac arrest, the cause of the cardiac arrest (the proximate cause) would be the pulmonary embolism and not the fall. Medical causes can include cardiovascular, chemical, dermatologic, endocrine, environmental, gastroenterologic, genetic, hematologic, gynecologic, iatrogenic, infectious, musculoskeletal, neurologic, nutritional, obstetric, oncologic, otolaryngologic, pharmacologic, psychiatric, pulmonary, renal, rheumatologic, toxic, traumatic, or urologic causes; medical conditions can be causes as well.

Property	Expected Type	Description
Properties from MedicalCause
`causeOf`	MedicalEntity	The condition, complication, symptom, sign, etc. caused.
Properties from MedicalEntity
`code`	MedicalCode	A medical code for the entity, taken from a controlled vocabulary or ontology such as ICD-9, DiseasesDB, MeSH, SNOMED-CT, RxNorm, etc.
`guideline`	MedicalGuideline	A medical guideline related to this entity.
`legalStatus`	DrugLegalStatus or MedicalEnumeration or Text	The drug or supplement's legal status, including any controlled substance schedules that apply.
`medicineSystem`	MedicineSystem	The system of medicine that includes this MedicalEntity, for example 'evidence-based', 'homeopathic', 'chiropractic', etc.
`recognizingAuthority`	Organization	If applicable, the organization that officially recognizes this entity as part of its endorsed system of medicine.
`relevantSpecialty`	MedicalSpecialty	If applicable, a medical specialty in which this entity is relevant.
`study`	MedicalStudy	A medical study or trial related to this entity.
Properties from Thing
`additionalType`	URL	An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. In RDFa syntax, it is better to use the native RDFa syntax - the 'typeof' attribute - for multiple types. Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.
`alternateName`	Text	An alias for the item.
`description`	Text	A description of the item.

`identifier`	PropertyValue or Text or URL	The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.
`image`	ImageObject or URL	An image of the item. This can be a URL or a fully described ImageObject.
`mainEntityOfPage`	CreativeWork or URL	Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details. Inverse property: mainEntity.
`name`	Text	The name of the item.
`potentialAction`	Action	Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
`sameAs`	URL	URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website.
`url`	URL	URL of the item.

Instances of MedicalCause may appear as values for the following properties

Property	On Types	Description
`cause`	MedicalCondition or MedicalSignOrSymptom	Specifying a cause of something in general. e.g in medicine , one of the causative agent(s) that are most directly responsible for the pathophysiologic process that eventually results in the occurrence.

<h1>Stable angina (angina pectoris)</h1>
Stable angina is a medical condition that affects the heart. The
most common causes are atherosclerosis and spasms of the
epicardial artery. Typical symptoms include:
<ul>
  <li>chest discomfort</li>
  <li>feeling of tightness, heaviness, or pain in the chest</li>
</ul>
Both stable angina and a heart attack result in chest pain, but
a heart attack will have chest pain lasting at least
10 minutes at rest, repeated episodes of chest pain at rest
lasting 5 or more minutes, or an accelerating pattern of chest
discomfort (episodes that are more frequent, severe,
longer in duration, and precipitated by minimal exertion).
<br>
Risk factors for stable angina include:
<ul>
  <li>Age</li>
  <li>Gender</li>
  <li>Systolic blood pressure</li>
  <li>Smoking</li>
  <li>Total cholesterol and/or cholesterol:HDL ratio</li>
  <li>Coronary artery disease</li>
</ul>
The initial treatment for stable angina is usually drug therapy
with aspirin, beta blockers, ACE inhibitors, and/or nitroglycerine.
Future episodes of stable angina can sometimes be prevented by
stopping smoking, weight management, and increased physical activity.
