This paper provides an informative overview of congestive heart failure (CHF), examining how the disease affects the heart's ability to circulate blood and the widespread burden it places on the population. Drawing on national and Arizona-specific statistics, the paper outlines the demographic groups most affected, describes the physiological progression of symptoms, and surveys the full range of treatment approaches — from medication and surgery to preventive education and patient self-care. The paper emphasizes that while there is no cure for CHF, proactive lifestyle modification and health literacy can significantly reduce risk and improve quality of life for those living with the condition.
The heart is one of the most vital muscles in the body. The body depends on the heart to pump oxygen- and nutrient-rich blood throughout the circulatory system. There are four chambers in the heart that collect blood from the body and send it back out to the lungs and the rest of the body. When a heart muscle valve fails, the circulation of blood is reduced, creating serious health consequences for the individual (Savarese & Lund, 2017).
In Arizona, there are 223 cardiovascular deaths per 100,000 people annually (United Health Foundation, 2019). Because congestive heart failure is not a seasonal issue but rather a lifestyle issue, these figures remain fairly constant from year to year. This is consistent with national figures: there are approximately 5 million people in the United States living with congestive heart failure (Savarese & Lund, 2017).
Congestive heart failure can affect people of all ages, from children and young adults to the middle-aged and the elderly. Breaking these figures down, 1.4 million people under the age of 60 have congestive heart failure. Approximately 2% of the middle-aged population (ages 40 to 59) are affected. The largest group experiencing congestive heart failure is the elderly population (ages 60 to 69), among whom 5% are impacted by the disease (Savarese & Lund, 2017). Annual incidence in the elderly population is near 10 per 1,000 people. The disease is also responsible for 11 million physician visits each year and more hospitalizations than all forms of cancer combined (Savarese & Lund, 2017). Overall, congestive heart failure accounts for approximately 287,000 deaths each year (Conrad et al., 2018).
The symptoms of congestive heart failure develop in a characteristic progression. As cardiac output decreases, blood pressure drops, resulting in dizziness and palpitations. Fluid builds up in tissues, the liver becomes congested, and fluid accumulation in subcutaneous tissue results in peripheral edema and bowel congestion, which causes nausea and decreased appetite. Fluid accumulation in the blood vessels leads to rapid weight gain. As blood flow decreases to muscles and other tissues, pulmonary edema develops, manifesting as a persistent cough due to decreased lung-blood oxygen exchange. Breathing becomes laborious, and less oxygen and fewer nutrients are transmitted to the brain (Savarese & Lund, 2017).
Treatments for congestive heart failure vary widely. There is no cure for this disease, so management focuses primarily on improving quality of life and slowing progression. How aggressively the condition is treated depends largely on its severity — the more advanced the disease, the more challenging effective treatment becomes.
Care treatments can include any of the following approaches:
Typically, treatment focuses on managing symptoms and reversing or preventing further damage where possible (Savarese & Lund, 2017).
Another important approach to addressing this disease is preventive care, which involves educating people about the health behaviors that put them at risk for congestive heart failure. Increasing health literacy — particularly around reducing risk through improved diet and regular exercise — is an effective way to prevent the disease. People also need to be educated about what the early signs of congestive heart failure look like.
Once people understand those signs, they need to know how to respond to them. They must be taught how to maintain control over the situation rather than allowing the situation to control them. In this sense, prevention represents the vast majority of the solution.
