Congestive Heart Failure is the Number One Reason For Hospitalizations Amongst Older Adults: "What We Don’t Know We Don’t Know in Health Care

Introduction: 

I felt strongly compelled to write this blog on heart failure as it is such a pertinent issue in the aging population today. Before I go into details on this, I’d like to address the definition of this disease process. Heart failure occurs when the heart doesn’t pump well and fails to deliver adequate oxygen to the body. As a result, fluid builds up in the body and vital organs don’t get the blood that they need. This can make it harder for individuals to perform everyday tasks and can lead to eventual overall decline. 

Problem:

Heart failure is the number one reason for hospital admissions in older adults, and often leads to multiple readmissions (Agarwal et. al., 2021). As a cardiac nurse for many years, I can attest to the fact that heart failure is the biggest reason for multiple hospitalizations in seniors. Patients come in and out for problematic symptoms, sometimes coming into the hospital as often as every month. The three biggest symptoms I see that result in hospital admissions are shortness of breath (particularly when lying flat), weight gain, and swelling in the legs.

One reason for such frequent admissions is the complexity of heart failure itself. It is a complicated clinical syndrome and is notoriously difficult to manage. A lot is put on patients to manage their heart failure at home, and this can be a challenge. In addition, individuals may have some level of cognitive impairment or multiple other comorbidities, making it even more challenging to perform the extensive monitoring needed to prevent heart failure from worsening.

The importance of education:

Education is also important in the treatment of heart failure. Unfortunately, this often does not get done. When I first started working in acute care back in 2004, every patient received extensive education in managing their heart failure prior to discharge. Nurses would provide lengthy verbal education on the importance of medication adherence, daily weights, low salt diet, and other factors, in addition to providing the patient with a heart failure educational pamphlet prior to discharge. Over the years, however, hospitals have increasingly faced staffing shortages and high nurse turnover. As a result, a lot of important patient education is not getting addressed. A lack of awareness and understanding in patients on how to manage their heart failure is definitely a key reason for worsening heart failure and repeated hospitalizations.

Management:

From a clinician standpoint, the goal in addressing heart failure is twofold: we want to reduce symptoms and prevent mortality. The best way to do this is through patient/family education and implementation of a treatment plan. A proper treatment plan will include such lifestyle modifications as a low salt diet, quitting smoking, and getting regular physical activity. A low salt diet can be incredibly helpful in preventing further fluid build up in the body. The American Heart Association recommends that all individuals consume no more than 2,300 mg of sodium per day (AHA, 2024). In today’s era of processed and packaged food, a majority of the American population consumes much more than that, and it comes in the food itself rather than the saltshaker. Maintaining a low sodium diet has one other priceless benefit that I often do not see emphasized enough in heart failure: it can help reduce blood pressure. Almost half of all heart failure patients have uncontrolled hypertension (Heart Failure, 2022). It is a major risk factor in the development of heart failure and managing it can greatly reduce heart failure symptoms and decrease stress on the heart. Current guidelines recommend maintaining a systolic blood pressure of less than 130.

Medication management is another important factor in the management of heart failure. This often includes the use of diuretics, beta blockers, and other medication classes that I will not go into detail on. I wanted to discuss diuretics and beta blockers because these are the two medications in heart failure that I see non-compliance with the most. I witness individuals often not taking one or the other for two main reasons:  they either don’t understand the importance of them or they don’t like the side effects. Seniors can often have difficulty getting up to go to the restroom. Diuretics cause frequent trips to the restroom because their purpose is to get excess fluid off the body. Many individuals do not comply with their prescribed diuretic because of the hassle of frequent bathroom trips. Unfortunately, ineffective diuresis causes heart failure to worsen and puts further stress on the heart. I often see non-adherence to beta blockers due to their side effects. The two biggest symptoms that get reported to me are fatigue and dizziness. As in the diuretic, a beta blocker can also help reduce the stress on the heart, and heart failure symptoms can worsen if the prescribed dose is not adhered to. It’s important to maintain prescribed medication regime and if any negative symptoms are experienced to discuss them with the doctor.

One final thing:

I wanted to touch on one final monitoring recommendation for heart failure because it so often gets missed: daily weights. Weighing oneself daily is of tantamount importance in heart failure and can identify early on if heart failure is worsening. This can lead to early intervention, thus decreasing potential hospitalization. Adherence to this all too often does not occur. I see patients come into the hospital for large amounts of weight gain… often 20 or more lbs. Many patients report that they never stepped on the scale to assess for weight gain and often do not get admitted to the hospital until symptoms are severe such as severe weakness and shortness of breath. In heart failure it’s recommended to contact the doctor if weight goes up by more than 2 pounds in a day or greater than 4 pounds in a week. The doctor can make modifications in the treatment regime and hence reduce potential hospitalizations and mortality.

Conclusion:

Heart failure is complex but manageable. Early action can prevent hospital admissions, reduce mortality, and optimize quality of life. Having ongoing guidance from an experienced clinician can be of great benefit if you or your loved one is having difficulty managing heart failure and other disease processes. Please do not hesitate to reach out to me if you have any further questions. I want to help and make the process of aging as stress free as possible while promoting positive health outcomes.
