8
Q
Sex
A
Men develop heart disease 10 years earlier on average than women, especially with low testosterone. However, women catch up postmenopausal
9
Q
Race
A
African Americans are more at risk. In part due to being at risk for hypertension. Hispanics living in America are about 25% less likely to die of heart disease than non-Hispanic whites. May be due to lower smoking rate in general

50
38
what can chest pain cause? (3)
angina pectoris
hyperventilation
acute MI
39
most common cause of chest pain
angina pectoris
40
lease common cause of chest pain
acute MI
41
angina pectoris is usually
brief, resulting from temporary ischemia of the myocardium
42
hyperventilation is
common
43
acute MI pain is usually
prolonged
44
most important symptom of angina pectoris
chest pain
45
angina pectoris is usually described as a sensation of (3)
aching, heavy, squeezing pressure
46
angina pectoris is tightness in the
midchest region
47
Area of discomfort with angina pectoris often is reported to be the size of a fist and may radiate into the (4)
left or right arm, neck or mandible
48
Pain of angina pectoris is of brief duration, lasting - to - minutes if the provoking stimulus is stopped
5-15
49
cause of angina pectoris
Blood supply to the cardiac muscle is insufficient for oxygen demand (atherosclerosis or coronary artery spasm)
50
angina pectoris can be observed in absence of (3)
coronary obstruction-anemia, hypoxemia, or profound hypotension
51
Angina episodes may be precipitated by (3)
stress, anxiety, or physical activity
52
someone with angina pectoris can have hypertension due to the (2) but vitals are usually normal
pain, and possible anxiety
53
Angina is defined in terms of its pattern of
symptom stability
54
STABLE Angina
is pain that is predictable, reproducible, unchanging, and consistent over time. Pain typically is precipitated by physical effort such as walking or climbing stairs but can occur with eating or stress
55
stable angina may be confused for
indigestion
56
Pain of stable angina is relieved by (3)
cessation of the precipitating activity, by rest, or the use of nitroglycerin
57
Most patients with chronic stable angina have underlying
Coronary Artery Disease. The plaques tends to be slow growing and relatively stable.
58
UNSTABLE ANGINA
Is defined as new-onset pain, increasing in frequency, and/or intensity, and is precipitated by less effort than before. It can also occur at rest
59
The pain of unstable angina is not readily relieved by
nitroglycerin
60
The key feature of unstable angina is the (2)
changing character (increasing intensity, frequency) or pattern of pain
61
Patients with stable angina have a relatively good
prognosis
62
Patients with unstable angina have a poorer prognosis and often experience an -- -- within a short time
acute MI
63
SKIPPED
| nitroglycerin study example (5)
STUDY: 380 patients with documented Coronary AD and angina
At least one risk factor was present in 96% of the patients
Only 46% of the patients had a prescription for SNG
Of those with a prescription for SNG, only 65% were informed by the physician on the proper use
Of those who were routinely carrying SNG, 37% had an expired product
64
nitroglycerin exerts action in
2-4 min
65
nitroglycerin duration of action is
30 min
66
side effects of nitroglycerin (4)
pounding in head
flushing
tachycardia
possible hypotension
67
angina pectoris treatment steps (5)
```
Stress reduction protocol
Avoid excess vasoconstrictors
Oxygen as necessary
Nitroglycerine tabs
Small bottle (plastic or metal, often keychain case, 1-2 tabs sublingual)
4444 if doesn’t go away
```
68
with angina pectoris treatment, place patient in what position?
sitting-up or semi-sitting position with head elevated
69
why do we put them in this position?
Ensure open airway and breathing is adequate
70
what do we check next?
vitals
71
Dispense/administer nitroglycerin either tablet or spray sublingually. Repeat every
5 minutes up to 3 doses in a 15-minute time period
72
Always check BP between each dose. If the systolic BP drops below 100mm/Hg do not give an additional dose of Nitroglycerin. Do not want to create profound (2)
hypotension and reflex tachycardia
73
what life threatening outcome can angina pectoris lead to
hypotensive shock
74
If pain is not relieved, (2)
give one aspirin 325 mg and call 911
75
Viagra was originally developed by Pfizer for the treatment of (2)
hypertension and angina pectoris
76
Women and men report different symptoms of MI, with fewer women experiencing --- --- but more often experiencing (2)
chest pain
| fatigue and dyspnea
77
Patients who have experienced an acute MI should be
hospitalized or receive emergency treatment as soon as possible
78
Basic management goal is to (2)
minimize the size of the infarction and prevent death from lethal arrhythmias
79
Early administration of aspirin is recommended, with 160-325 mg being chewed and swallowed to (2)
decrease platelet aggregation and limit thrombus formation
80
signs and symptoms of MI
Development of chest pain
Cyanotic, pale, or ashen appearance
Death of cardiac muscle due to inadequate blood oxygen supply
The condition may progress to cardiac arrest
With unresponsive patients-initiate CPR, including use of automated external defibrillator (AED)
81
Development of chest pain, sometimes manifested as a (3) feeling, that is more severe than with angina and lasting longer than 15 minutes; and is not relieved by nitroglycerin in a conscious patient
crushing, squeezing or heavy
82
Cyanotic, pale, or ashen appearance
weakness, cold sweat, nausea, vomiting, air hunger and sense of ‘impending death’ irregular pulse
83
acute MI is a
heart attack
84
acute MI is a lack of
O2 to tissues
85
lack of O2 to tissues causes
ischemia (damage)
86
what occurs after 4-6 hours of actor MI?
permanent damage (necrosis)
87
plaque ruptures can result in
thrombus (blood clot) formation
88
Dental treatment of Post-Myocardial Infarction
< 8 weeks out:
> 8 weeks out:
< 8 weeks out, No elective Dental Treatment
> 8 weeks out, Elective Dental Treatment possible, need to: Obtain a Medical Consultation-what is the patient’s cardiac status? Is the patient’s cardiac condition stable? What is the patient’s ejection fraction? Does the patient have any degree of heart failure?
