Special Pops Exam 3 Flashcards
1
Q
Miocardial Infarction Pathophysiology
A
- Endothelial dysfunction
- Inflammation (C reactive protein CRP)
2
Q
Miocardial Infarction Signs and Symptoms
A
- Chest px/pressure
- sweating nausea vomiting
- INC cardiac enzymes; creatine kinase, troponin
- means cells died/exploded into blood stream
- EKG changes
3
Q
Exercise Stress Test Goals Cardiac
A
- reproduce angina
- EKG changes
4
Q
Angina pathophysiology
A
- Ischemia/hypoxia
- obstruction
- heavy constriction behind sternum
- radiating px
- short of breath, nausea
- 2-10 min
5
Q
Angina Silent, unstable, triggers, treatment
A
Silent -asymptomatic/ diabetes Triggers -rest/nitroglicerine Unstable -less predictable/at rest -INC severity, freq, duration, threshold -precurser to MI (anticoagulants/ angioplasty)
6
Q
Cardiac Interventions
A
REVASCULARIZATION -CABG -PTCA IMPLANTABLE DEVICES -pacemaker/defibrilator VALVE REPLACEMENT TRANSPLANT LIFESTYLE -exercise/diet/stop smoking MEDICATION SURGERY
7
Q
Goal of Cardiac interventions
A
- increased heart function
- angiogenesis
- fibrolysis
- vagal tone
8
Q
Exercise Testing Cardiac
A
- inc pt confidence
- evaluate
- HR capacity/recovery
- aerobic and myocardial capacity
- symptoms
- EKG changes
- NO graded Ex test (use pharmacological)
- get to ischemic threshold
9
Q
Cardiac EX RX
A
RESISTANCE progress slowly F-2-3 d/wk I-RPE 11-13 T-12-15 reps CV F-4-7 d/wk I-RPE 11-16, below ischemic/shock threshold T-Long warmup/cooldown progress to 20-60 min T- varied aerobic
10
Q
Special Cardiac Considerations
A
- sternotomy
- ECG monitoring
- transplants
- Return to work (specificity)
11
Q
Cardiac Rehab
A
Phases 1 inpatient 2 12 weeks, egg monitored/discharged 3 intermittent/no ecg/ supervision 4 no ecg, supervision
12
Q
COPD causes
A
narrowing of airways limiting airflow
- most common (80 smokers)
- small airway inflammation
- dificulty breathing out
- athsma
- cystic fibrosis
13
Q
Restrictive PD
A
restrict lung expansion
- neuromuscular/neurological
- trouble breathing IN
14
Q
COPD Signs and symptoms
A
-dyspnea
neuro input form chemo and mechano receptors
-wheezing
-chronic cough
15
Q
COPD consequences
A
- ventilatory impairments (resistance/recoil)
- abnormal gas exchange (inc hemoglobin)
- CV impairments
- muscle impairments
- breathlessness
- psychological
