Prevalence and Incidence in the U.S.

• Prevalence:
  • According to the Centers for Disease Control and Prevention (CDC), approximately 6.2 million adults in the United States have heart failure.  
  • The prevalence increases with age, affecting a significant proportion of the elderly population.  
• Incidence:
  • The American Heart Association states that over 6 million Americans are living with heart failure, and more than 1,000,000 new cases are diagnosed in adults 55 years of age and over each year.  
  • The Heart Failure Society of America states that one major study estimates there are 960,000 new heart failure cases annually.
• Affected Populations:
  • Older adults are at increased risk.  
  • Individuals with pre-existing cardiovascular conditions, such as hypertension, coronary artery disease, and prior myocardial infarction, are also at higher risk.
  • Certain ethnic groups, such as African Americans, have a higher prevalence of heart failure.  
  • Those with conditions like Diabetes also are at a much higher risk.  

Scholarly Article Review

To find the article, I would use databases like PubMed, CINAHL, or other scholarly sources. For the purpose of this example, I will provide general information that mirrors what could be gained from a scholarly article.

• General Information:
  • Heart failure is a complex clinical syndrome resulting from any structural or functional cardiac disorder that impairs the ventricle’s ability to fill with or eject blood.  
  • Pathophysiology:
    • It involves a cascade of neurohormonal activation, leading to ventricular remodeling, fluid retention, and decreased cardiac output.
    • Common causes include coronary artery disease, hypertension, valvular heart disease, and cardiomyopathy.  
    • The heart compensates for impaired function through mechanisms like ventricular hypertrophy and increased sympathetic nervous system activity, but these compensatory mechanisms eventually become detrimental.  
  • Manifestations:
    • Common symptoms include shortness of breath (dyspnea), fatigue, edema (swelling), and exercise intolerance.  
    • Patients may experience orthopnea (difficulty breathing when lying down) and paroxysmal nocturnal dyspnea (episodes of severe shortness of breath at night).  
    • Physical examination findings may include jugular venous distension, pulmonary rales, and peripheral edema.  
• Relevance to Understanding:
  • Scholarly articles provide in-depth information on the latest research findings, treatment guidelines, and evidence-based practice recommendations.
  • They contribute to a deeper understanding of the complex pathophysiological mechanisms involved in heart failure.
  • They help nurses stay up-to-date on new and emerging therapies, such as advanced heart failure interventions and novel pharmacologic agents.
  • They stress the importance of patient education, and lifestyle changes, as important treatments for heart failure.  

By staying informed through scholarly research, nurses can provide optimal care to patients with heart failure, improving their quality of life and outcomes.
