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.
`description`	Text	A short description of the item.
`image`	URL	URL of an image of the item.
`name`	Text	The name of the item.
`url`	URL	URL of the item.
Properties from MedicalEntity
`alternateName`	Text	Any alternate name for this medical entity.
`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.
`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 MedicalCondition
`associatedAnatomy`	AnatomicalStructure or AnatomicalSystem or SuperficialAnatomy	The anatomy of the underlying organ system or structures associated with this entity.
`cause`	MedicalCause	An underlying cause. More specifically, one of the causative agent(s) that are most directly responsible for the pathophysiologic process that eventually results in the occurrence.
`differentialDiagnosis`	DDxElement	One of a set of differential diagnoses for the condition. Specifically, a closely-related or competing diagnosis typically considered later in the cognitive process whereby this medical condition is distinguished from others most likely responsible for a similar collection of signs and symptoms to reach the most parsimonious diagnosis or diagnoses in a patient.
`epidemiology`	Text	The characteristics of associated patients, such as age, gender, race etc.
`expectedPrognosis`	Text	The likely outcome in either the short term or long term of the medical condition.
`naturalProgression`	Text	The expected progression of the condition if it is not treated and allowed to progress naturally.
`pathophysiology`	Text	Changes in the normal mechanical, physical, and biochemical functions that are associated with this activity or condition.
`possibleComplication`	Text	A possible unexpected and unfavorable evolution of a medical condition. Complications may include worsening of the signs or symptoms of the disease, extension of the condition to other organ systems, etc.
`possibleTreatment`	MedicalTherapy	A possible treatment to address this condition, sign or symptom.
`primaryPrevention`	MedicalTherapy	A preventative therapy used to prevent an initial occurrence of the medical condition, such as vaccination.
`riskFactor`	MedicalRiskFactor	A modifiable or non-modifiable factor that increases the risk of a patient contracting this condition, e.g. age, coexisting condition.
`secondaryPrevention`	MedicalTherapy	A preventative therapy used to prevent reoccurrence of the medical condition after an initial episode of the condition.
`signOrSymptom`	MedicalSignOrSymptom	A sign or symptom of this condition. Signs are objective or physically observable manifestations of the medical condition while symptoms are the subjective experienceof the medical condition.
`stage`	MedicalConditionStage	The stage of the condition, if applicable.
`subtype`	Text	A more specific type of the condition, where applicable, for example 'Type 1 Diabetes', 'Type 2 Diabetes', or 'Gestational Diabetes' for Diabetes.
`typicalTest`	MedicalTest	A medical test typically performed given this condition.

<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.
