Study Notes
Right-Sided Heart Failure
- Causes fluid buildup in the body, leading to swelling
- Occurs when the right ventricle cannot pump blood effectively to the lungs
Stages of Heart Failure
- Stage A: High risk of heart failure, but no symptoms
- Stage B: Heart damage without symptoms
- Stage C: Heart damage with symptoms like fatigue or shortness of breath
- Stage D: Advanced heart failure with severe symptoms
Causes of Heart Failure
- Coronary Artery Disease: Narrowing of heart arteries due to atherosclerosis
- Hypertension: High blood pressure increases heart workload
- Valvular Heart Disease: Problems with heart valves increase pressure on the heart
Cardiogenic Shock
- Occurs when the heart cannot pump enough blood to the body
- Typically stems from severe left-sided heart failure
-
Pathophysiology:
- Decreased Heart Contraction: Leads to a drop in stroke volume and reduced cardiac output
- Pulmonary Congestion: Blood backs up in the lungs, causing congestion
- Compensation: Heart beats faster, but doesn't help enough
- Decreased Stroke Volume: Less blood reaches the coronary arteries, reducing oxygen supply to the heart
- Increased Workload: Worsens heart failure
- Final Outcome: Low oxygen to the heart leads to further reduced cardiac output and triggers compensatory mechanisms to prevent death
Causes of Cardiogenic Shock
- Coronary Causes: Most commonly due to heart attack (myocardial infarction)
- Non-Coronary Causes: Conditions like cardiomyopathy or stress on the heart muscle
Symptoms of Cardiogenic Shock
- Cool, clammy skin
- Low blood pressure
- Rapid heart rate (tachycardia)
- Fast, shallow breathing
- Decreased urine output
- Confusion and cyanosis (bluish skin)
- Auscultation: Detects abnormal heart sounds
Diagnosis of Cardiogenic Shock
- Pulmonary Artery Pressure (PAP): Measures increased pressure
- Arterial Pressure Monitoring: Shows low blood pressure
- ABGs: Detects metabolic acidosis and low oxygen
- ECG & Echocardiography: Confirms heart damage
- Enzyme Tests: Confirms heart attack
Management of Cardiogenic Shock
- Monitor arterial lines and fluid therapy
- Adjust balloon pump for heart rhythm
- Provide medications to relieve pain and monitor oxygen and acid-base levels
Lifestyle Changes for Prevention of Heart Disease
- Control blood pressure
- Avoid smoking
- Maintain a healthy weight
- Eat a low-fat diet
- Exercise regularly
Expected Outcomes of Cardiogenic Shock Treatment
- Stable heart function
- Relief of symptoms
- Successful treatment of cardiogenic shock
Heart Failure
- Condition where the heart cannot pump enough blood to meet the body's needs
- Can involve problems with either the heart's ability to contract (systolic dysfunction) or to fill with blood (diastolic dysfunction)
- Main goal of treatment is to manage symptoms and prevent further heart damage
Types of Heart Failure
- Left-Sided Heart Failure: Causes fluid buildup in the lungs, leading to breathing problems
- Right-Sided Heart Failure: Causes fluid buildup in the body, leading to swelling in areas like the legs
Hypertensive Emergencies and Urgencies
- Occur when blood pressure is dangerously high
- Often due to poor control or stopping medications abruptly
Hypertensive Emergency
- Blood pressure is extremely high (above 180/120 mm Hg) and must be lowered immediately to prevent organ damage
- Conditions linked include: Pregnancy-related hypertension, heart attack, aortic aneurysm, brain hemorrhage
Symptoms of Hypertensive Emergency
- Severe headache
- Nausea and vomiting
- Confusion
- Vision changes
- Chest pain
- Shortness of breath
- Seizures
Hypertensive Urgency
- Blood pressure is very high, but no organ damage is seen
- Symptoms may include: Headaches, nosebleeds, or anxiety
Treatment of Hypertensive Urgency
- Oral medications like labetalol, captopril, or clonidine can lower blood pressure over 24-48 hours
Monitoring of Hypertensive Urgency
- Blood pressure is checked frequently - every 5 minutes if it’s changing quickly, or every 15-30 minutes in stable situations
- Sudden drops in blood pressure may require immediate intervention
Cardiomyopathy
- Disease of the heart muscle that affects its ability to pump blood
-
Types:
- Dilated cardiomyopathy (DCM) (most common)
- Hypertrophic cardiomyopathy (HCM) (rare, often inherited)
- Restrictive cardiomyopathy (RCM)
- Arrhythmogenic right ventricular cardiomyopathy (ARVC)
- Unclassified cardiomyopathies (with features of multiple types)
Pathophysiology of Cardiomyopathy
- Leads to decreased heart function and reduced blood output
- Triggers responses in the body that increase fluid retention and place extra stress on the heart, often leading to heart failure
Symptoms of Cardiomyopathy
- Heart failure signs: Shortness of breath, fatigue, and fluid retention.
Left-Sided Heart Failure
- Symptoms: Shortness of breath, cough, and lung crackles.
Right-Sided Heart Failure
- Symptoms: Swelling in the legs and abdomen, loss of appetite.
Diagnosis of Heart Failure
- ECG and Chest X-ray: Check heart size and function
- Echocardiogram: Measures heart chambers and ejection fraction
- Blood Tests: Look for kidney function and electrolyte levels
Treatment of Heart Failure
- Medications: ACE inhibitors, beta-blockers, and diuretics reduce strain on the heart and control fluid buildup.
- Lifestyle: Low-sodium diet, regular exercise, and quitting smoking.
Nursing Management of Left-Sided Heart Failure
- Monitor symptoms like breathing difficulty and weight changes.
- Encourage activity in manageable amounts. Teach self-care: how to manage diet, medication, and recognize worsening symptoms.
Nursing Management of Cardiogenic Shock
- Reduce blood pressure by 25% in the first hour.
- Lower to 160/100 mm Hg within 6 hours.
- Gradually reduce further over several days.
- Medications: IV vasodilators like sodium nitroprusside, nicardipine, or nitroglycerin are used for quick action.
- Monitor fluid status to prevent a sudden drop in pressure.
Prevention of Heart Failure
- Maintain a healthy diet
- Engage in regular exercise
- Avoid smoking
