Week 6 - Cardiac Muscle Dysfuncton And Failure Parts 4 And 5 Flashcards
Treatment options for CHF
Lifestyle/dietarty/PA
Correct underlying problem medically - anti hypertensive meds to compensate
Devices to supplement heart’s output
Correct underlying problem surgically - repair/replace valve
Heart transplant
Medical management of heart failure
Directed at underlying cause/causes
Improve heart pump
Reduce workload
Control sodium intake and water retention
Dietary changes and nutritional supplementation management of heart failure
Supplement vitamins, minerals and amino acids
Decrease sodium intake
Fluid restrictions
Eating heart healthy food w low cholesterol/fat
What vitamins help maintain lab values with heart failure?
Vitamin E and C
Weigh daily to monitor fluid - management of heart failure
Rapid weight gain usually due to fluid retention
More than 3 pounds in one day usually requires hospitalization
Pharmacological treatments for HF
ACE inhibitors
Diuretics
Beta blockers
Digoxin
Pressures
ACE inhibitors
Decrease retention of water and vasoconstriction
Name ends in -opril
Angiotensinogen II receptor antagonists as alternative
Diuretics
Treat backward symptoms as maintenance or emergency
May combine for severe cases
Reduce fluid in veins reduces load on heart
Beta blockers
Decrease cardiac work
May be combined with ACEI and diuretic
Ameliorate effects of chronic elevation of catecholamines
Digoxin
Increase contractility, decrease HR
Used for arrhythmias
LOW THERAPEUTIC INDEX - low dose has to be used, small window for when it can be used therapeutically
Emergent use of pressers
Reserved for refractory CHF in ICU
Temp following surgery, illness, trauma
Increase contractility and BP through vasoconstriction
Maintenance until heart transplant
Physical activity management
Decrease/discontinue exhaustive activites
Decrease/discontinue full time work
Introduce rest periods during the day
Progressive exercise/activity that fluctuates
Exercise intensity set by level of dyspnea or below level of adverse response
Start with ADLs in hospital, enter cardiac rehab ASAP
Progression to resistance exercise is recommended
Mechanical devices
Pacemaker
Implantable cardiac defibrillator
Cardiac resynchronization therapy
What do pacemakers do?
Help with regulation
What does cardiac resynchronization therapy do?
Improve cardiac function and hemodynamics by coordinating the contraction
Dialysis and ultrafiltration
Removal of fluid from pleural and abdominal cavities
Assisted circulation
Intraaortic balloon counterpulsation using a pump (IABP)
Ventricular assist device
Provides force to eject blood
Left ventricular muscle flap - surgery management for chronic heart failure
Cardiomyoplasty - assists w LV contraction
L partial ventriculectomy (PLV) - surgical management for chronic heart failure
Reduces cardiac volume
Cardiac transplantation
Xenograft - non human primate
Allograft - human
Orthotopic
Heterotopic
Measuring left HF: pulmonary capillary wedge pressure
Estimates pressure in L atrium (preload)
Indicates severity of L ventricular HF
Pressure > 20 likely result in pulmonary edema
Causes: mitral or aortic stenosis/regurgitation
Signs and symptoms of decompensation
Cyanosis of hands, feet and lips
Dyspnea/SOB /DOE
Gurgling sounds
Pink, frothy sputum
Sudden onset of fatigue
Decreased HR or systolic BP
Benefits of exercise training as intervention
Improvement in symptoms, clinical status and exercise duration
Exercise training and QOL
QOL is related to ability to exercise
Exercise training during continuous intravenous dobutamine fusion
No adverse effects
No clinically significant differences
Exercise training w/ ventricular assist devices
Improved technology has enabled patients to exercise
Exercise training during CPAP ventilation
CPAP and BiPAP have improved exercise performance
Clinical practice guidelines for PT management of CHF
Advocate for increased total daily physical activity as an essential component of care
Educate on and facilitate self management of S/S of exacerbation, weight monitoring, nutrition, meds
For NYHA class II-III, physical activity/training should include:
Aerobic
HIIT: High intensity interval
Resistance
Combo resistance and aerobic
Inspiratory mm training
Combo inspiratory w aerobic
Initial interventions for CHF
Transfer and balance training
Low level, low impact (like walking, increasing as tolerated)
Breathing exercises: facilitate diaphragmatic breathing; inspiratory/expiratory exercises
What is the goal of energy conservation?
To decrease workload on heart without loss of function
Self management techniques for education
Assist patient with taking responsibility for own health
Monitor weight daily at same time everyday
Monitor symptoms w activity and being aware of increasing symptoms w activity
Optimization of medical therapy
Vigilant follow up
Early attention to fluid overload education
Watch daily weight and contact physican with changes
Watch amount of pillows needed for sleeping
