Caring for Patients With Cardiac
Disorders
Learning Outcomes
1. Compare and contrast the causes, pathophysiology,
effects, and manifestations of common cardiac
disorders.
2. Safely administer drugs commonly prescribed for
patients with heart disease.
3. Provide individualized and evidence-based nursing
care for patients undergoing invasive procedures or
surgery of the heart.
4. Use clinical judgment and the nursing process to
conduct focused assessments, contribute to care
planning, and provide individualized nursing care for
patients with disorders of the heart.
Learning Outcomes
5. Provide and reinforce appropriate teaching for
patients with heart disorders and their families,
taking patient values, expressed needs, and
preferences into consideration.
6. Use electronic resources for planning and
documenting nursing care for patients with heart
disorders.
Disorders of Cardiac Function
Heart Failure
• Inability of heart to function as pump
• Results from any condition that causes:
• Impaired contractions
• Increased workload of the heart
• Leading causes
• Hypertension
• CHD with myocardial ischemia and MI
Pathophysiology
• Cardiac output drops
• Compensatory mechanisms activated
• Sympathetic nervous system stimulated
• Arteries and veins constrict
• Venous return increases to the heart
• Increase in preload
Pathophysiology
• Renin–angiotensin–aldosterone system activated
• Salt and water retention
• Heart chambers dilate
• Ventricular hypertrophy
• Reduced cardiac reserve
• Classified as left-sided or right-sided
Pathophysiology
• Left-sided heart failure
• Manifestations
•
•
•
•
•

Manifestations of Heart Failure
Collaborative Care
• Diagnostic tests
• Cardiac hormones, atrial natriuretic factor, and brain
natriuretic peptide
• Serum electrolytes
• Chest x-ray
• Echocardiogram
• ECG
Collaborative Care
• Hemodynamic monitoring
• Assess cardiovascular function
• Multilumen catheter inserted through central vein in right side
of the heart
• Pulmonary artery used to measure central venous pressure,
pulmonary artery pressures, and cardiac output
• Arterial blood pressure measured using a peripheral arterial
line
The nurse observes tracings of a patient’s hemodynamic pressures. The
upper screen in the background shows (from top): heart rate (green);
arterial blood pressure (red and yellow); central venous pressure (CVP,
light blue); blood oxygen (dark blue); respiration rate (white).
