Allen CH5 Summary

Cardiac Care Study Notes

Diagnostic Information

  • Cardiovascular disease (CVD) involves plaque buildup in the cardiovascular system.
  • Leads to heart disease and cerebrovascular accidents (strokes).
  • Affected population:
  • ~82 million adults in the U.S. with some form of CVD.
  • Age group 60-79: 72.6% of men and 71.9% of women diagnosed.
  • Age 80+: 80.1% of men and 86.7% of women diagnosed.
  • CVD is the leading cause of death in the U.S., averaging one death every 39 seconds.

Major Categories of Heart Disease

  1. Coronary Heart Disease (CHD)
  • Caused by atherosclerosis: fatty plaques develop in heart arteries.
  • Types include:
    • Unstable angina: partial blockage causing chest pressure and breath shortness.
    • NSTEMI: Non-ST segment elevation myocardial infarction (less severe than STEMI).
    • STEMI: ST segment elevation myocardial infarction (severe heart attack).
  • Risk Factors:
    • Changeable: high cholesterol, smoking, high blood pressure, inactivity, obesity, diabetes.
    • Unchangeable: aging, male sex, hereditary.
  1. Arrhythmias
  • Disorders of the heart's electrical system.
  • Types:
    • Supraventricular (e.g., atrial fibrillation): irregular heartbeat.
    • Ventricular (e.g., ventricular tachycardia, ventricular fibrillation): can lead to sudden cardiac death.
    • Bradyarrhythmias: slow heart rhythms affecting blood flow.
  1. Valve Disease
  • Impaired valve function (e.g., mitral valve prolapse).
  • Common issues:
    • Valve narrowing, leaking, or stiffening leading to inefficient blood flow.
  1. Congestive Heart Failure (CHF)
  • Heart's inability to pump blood efficiently.
  • Compensation leads to fluid retention; can result in fluid backup into lungs.
  • Causes: hypertension, alcohol use, diabetes, etc.

Cardiac Rehabilitation

  • A structured approach to recovery after cardiac events.
  • Four Phases:
  1. Phase I: Begins in hospital focusing on mobility and assessment.
  2. Phase II: Gradual increase in physical activity (low-impact exercises).
  3. Phase III: Increasing intensity and duration of exercises.
  4. Phase IV: Emphasis on lifelong health behavior changes.

Psychological Considerations

Depression

  • A changeable risk factor for heart disease.
  • Symptoms include prolonged sadness, weight changes, insomnia, fatigue, and suicidal thoughts.
  • Linked to poor management of heart conditions and medication noncompliance.

Anxiety

  • Involves both emotional and physiological responses to stress.
  • Linked to onset but not progression of cardiac illness.
  • Techniques for Relief:
  • Relaxation techniques (meditation, deep breathing).

Anger/Hostility

  • Expressed as irritation or rage; can affect healthcare compliance.
  • Type A personality traits may contribute to hostility.

Stress

  • A physiological and psychological response influencing heart disease.
  • Chronic stress elevates cortisol, contributing to high blood pressure and inflammation.
  • Social Support: Critical in managing stress; low social support increases disease risk.

Music Therapy Interventions

  • Types of Music Therapy:
  1. Receptive: Music listening, music-assisted relaxation, guided imagery.
  2. Improvisational: Instrumental and vocal improvisation.
  3. Re-creative: Expressive singing and song transformation.
  4. Compositional: Songwriting and transformation of existing songs.

Applications of Music Therapy

  • Reduces anxiety and stress related to cardiac issues.
  • Promotes emotional expression and psychological well-being.
  • Enhances patient engagement and compliance during rehabilitation.

Research and Efficacy

  • Music therapy is effective in managing symptoms of anxiety, depression, and improving cardiac rehabilitation outcomes.
  • Further studies are needed to explore the best methods of music use during exercise and recovery programs.
