Most common cause of premature death in the world:
CVD
T/F: It is rare that a person will have just one type of cardiovascular disease
true - often they have a combination of the diseases
Patients with cardiovascular disease frequently have:
more than one CVD
List some examples of CVDs:
- HTN
- Atherosclerosis
- Angina pectoris
- CHF
- Arrhythmias
- Bacterial endocarditis
Of the following, which is the least likely to progress?
- HTN
- Atherosclerosis
- Angina pectoris
- CHF
- Arrhythmias
- Bacterial endocarditis
Bacterial endocarditis- an infectious disease process that is more related to the risk of getting certain bacteria and also a genetic predisposition to it as well
Coronary artery disease that leads to infarction:
Athersclerosis (Atherosclerotic Heart Disease) (ASHD)
Type of CVD characterized by infection, inflammation, and scarring of cardiac tissues
bacterial endocarditis
Type of CVD characterized by dilated ventricles with weak muscles and thickened myocardium
CHF
Type of CVD characterized by uncoordinated electrical signals
Arrhythmia
Common arrhythmias include:
bradycardia and tachycardia
Type of CVD characterized by stenotic heart that is not capable of full closer for blood circulation and leads to CHF.
Valvular disease
What can valvular disease lead to?
CHF
List the categories of CVD risk factors:
- Conditions
- Behavioral
- Family History
What are some conditions that serve as risk factors for CVD?
- high blood pressure
- high cholesterol
- diabetes
- rheumatic fever
- greater than 1 CVD
How does the condition HTN serve as a risk factor for CVD?
- stiffens vessels which reduces blood flow
- puts patient at risk for stroke, kidney disease, and dementia
How does the condition DM serve as a risk factor for CVD?
unstable glucose levels affect healthy myocardium function; angiopathy
What are some behavioral factors that serve as risk factors for CVD?
- unhealthy diet
- physical inactivity
- obesity
- excessive alcohol
- tobacco use
- stress
What aspects of an unhealthy diet may contribute to risk factors for CVD?
- carbs
- fats
- caffeine
- sodium
Why is obesity a risk factor for CVD?
excessive weight stresses heart function, and leads to HTN and CAD
How does physical inactivity lead to CVD?
poor circulation
How does too much alcohol put one at risk for CVD?
increases BP & arrhythmias
How does tobacco use put one at risk for CVD?
increases HR, BP, CAD etc.
List some components of family history that serve as risk factors for CAD:
- genetics
- ethnicity
- aging
What are some contributory anatomic abnormalities that puts one at risk for CVD?
- hypertrophy
- dilation
- valves
- regurgitation
- stenosis
When the heart has to work harder to pump blood, leading to a larger, less efficient heart:
hypertrophy
What are some physiologic changes that occur in the heart due to prior abnormalities (atherosclerosis, HTN, HLP)
(asking for more advanced heart conditions)
- arrhythmias
- heart failure
- ischemia
In terms of cardiac classification, which patients would we treat at UMKC?
Only Class I or Class II
New York Heart Association Heart Failure Classification (Symptom Based)
Physical Activity: No limitation
No dyspnea, fatigue or palpitations with physical activity
Class I
New York Heart Association Heart Failure Classification (Symptom Based)
Physical activity: Slight limitation
Fatigue, dyspnea, & palpitations are present with physical activity
Class II
New York Heart Association Heart Failure Classification (Symptom Based)
Physical activity: marked limitation
Less than normal physical activity results in symptoms. Comfortable at rest.
Class III
New York Heart Association Heart Failure Classification (Symptom Based)
Physical activity: Severely limited (exacerbates symptoms)
Symptoms present at rest
Class IV
As a dentist a stage 4 patient is a patient we don’t want to treat at all unless:
dental emergency (treat only in hospital setting)
Categorize the following as a sign or symptoms of CVD:
Elevated BP
sign
Categorize the following as a sign or symptoms of CVD:
Irregular or abnormal HR
sign
Categorize the following as a sign or symptoms of CVD:
abnormal respiratory rate
sign
Categorize the following as a sign or symptoms of CVD:
Pt is uncomfortable in supine position
symptom
Categorize the following as a sign or symptoms of CVD:
SOB upon exertion
sign
Categorize the following as a sign or symptoms of CVD:
prolonged bleeding/easy bruising
signs
Categorize the following as a sign or symptoms of CVD:
surgical scars
signs
The sign - prolonged bleeding/bruising - we see in patients with cardiac disease, is often times attributed to:
medications the patient may be taking to control cardiac disease
The less symptoms and the better the control of risk factors:
THEN the ___ a patient manages the stress
AND the ____ likely the patient will have a life threatening incident during a dental procedure
Better; less
The greater symptoms and the poorer the control of risk factors:
THEN the ___ a patient manages the stress
AND the ____ likely the patient will have a life threatening incident during a dental procedure
Worse; more
Medication risk categories of dental treatment:
- Low level intervention
- Moderate intervention
- High risk intervention
List some examples of LOW LEVEL INTERVENTION dental treatments:
- health/medical evaluation

- alginate impressions
List some examples of MODERATE LEVEL INTERVENTION dental treatments:
- SRP
- Simple restorative procedures; 1-2 teeth
- Simple extractions (1-2 teeth)
- Restorative impressions needing retractions and longer setting times
List some examples of HIGH RISK LEVEL INTERVENTION dental treatments:
