Heart Failure and the Nursing Process: A Clinical Reference

My final paper (Karya Tulis Ilmiah) for the Diploma III in Nursing at Universitas Muhammadiyah Banjarmasin was a nursing care report: a case study written after a period of clinical practice in the cardiology ward of Ulin General Hospital, Banjarmasin, applying the full nursing process, assessment, diagnosis, intervention, implementation, and evaluation, to a real patient with heart failure.

I’m not publishing that case report here. It documents a real person’s real medical history in detail, and the consent he gave in 2016 was for an academic paper reviewed by my instructors, not for indefinite publication on the internet. What I can share, and what has value independent of any one patient, is the clinical knowledge behind it: what heart failure is, why it happens, and how nurses are trained to plan care around it.

What Heart Failure Is

Heart failure is a clinical syndrome in which the heart cannot fill with or pump blood well enough to meet the body’s metabolic demands (Bender et al., 2010; Mohrman & Heller, 2014). It isn’t a single disease so much as the endpoint of several: most often the lasting damage left by a heart attack, but also hypertension, valve disease, and inflammatory or structural heart conditions, any of which can leave the heart muscle unable to keep up (LeMone et al., 2011).

It’s also more common than the word “failure” might suggest. Global estimates put the number of people living with heart failure at roughly 23 million, with prevalence in the United States alone projected to reach 10 million people by 2040 (Deedwania & Mather, 2014). In Indonesia, national health survey data from 2013 put diagnosed prevalence at 0.13%, rising when symptomatic-but-undiagnosed cases are counted; in Kalimantan Selatan specifically, the province where I trained, that figure was similar, and at Ulin General Hospital, heart failure was the single most common diagnosis in the cardiology ward across both 2013 and 2014, ahead of coronary heart disease and atrial fibrillation (Badan Penelitian dan Pengembangan Kesehatan, 2013; Bidang Pendidikan dan Penelitian RSUD Ulin, 2013, 2014). It’s a common condition to end up nursing, not a rare one.

Why It Happens

Coronary heart disease is the most frequent cause: a heart attack damages muscle tissue, and the heart compensates in the short term by raising heart rate and constricting blood vessels to hold blood pressure steady, at the cost of extra strain that eventually shows up as reduced capacity (McDonagh et al., 2011). Chronic hypertension causes a slower version of the same problem: the left ventricle thickens to cope with the added resistance it’s pumping against, which briefly preserves function but eventually stiffens the chamber and interferes with how well it fills between beats. Valve disease, whether it’s a valve that won’t open fully (stenosis) or won’t close fully (regurgitation), forces the heart to work harder to move the same volume of blood, and arrhythmias can be either a cause of heart failure or a consequence of the structural changes it produces, which makes the two hard to fully untangle in a given patient. Less commonly, heavy alcohol use or, in a small number of cases, pregnancy itself (peripartum cardiomyopathy) can trigger the same syndrome (McDonagh et al., 2011).

Reading the Severity

Two classification systems do most of the work here, and they answer different questions. The New York Heart Association (NYHA) scale is functional: it asks how much physical activity a person can do before symptoms show up, from Class I (no limitation) to Class IV (symptoms even at rest). The American College of Cardiology and American Heart Association (ACC/AHA) staging is structural and describes where someone sits on the road to heart failure, from Stage A (at risk, no disease yet) to Stage D (refractory, end-stage disease) (Samara & Tang, 2012). NYHA class can move up and down as a patient’s condition changes week to week; ACC/AHA stage generally only moves forward. Used together, they answer both “how is this person doing right now” and “how far has the underlying disease progressed.”

How It’s Diagnosed

An ECG is the first, cheapest, and most telling test: a genuinely normal ECG makes heart failure unlikely, and an abnormal one can point toward a prior heart attack or identify who might respond to specific therapies (McDonagh et al., 2011). Blood work adds detail: natriuretic peptides (BNP and NT-proBNP) rise in proportion to how severe the dysfunction is, troponin flags active muscle damage, and routine tests like electrolytes, kidney function, liver function, and a full blood count catch the complications and comorbidities that commonly ride along with heart failure, anemia, kidney strain, hepatic congestion. A chest X-ray can show an enlarged heart or fluid backing up into the lungs, though a normal-looking film doesn’t rule anything out, since roughly half of confirmed cases still show a normal cardiothoracic ratio. Echocardiography is the workhorse imaging study, giving a direct, non-invasive look at how the muscle and valves are actually functioning, and cardiac MRI is increasingly used where a more precise picture of the tissue itself is needed.

How Nurses Plan Care

The nursing process turns a diagnosis into a repeatable plan, and for heart failure it usually centers on five recurring problems (Taylor & Ralph, 2013):

Decreased cardiac output. The core concern is whether the heart is actually moving enough blood. Nursing care here is largely about surveillance, tracking vital signs, heart and lung sounds, fluid intake and output, and daily weight, catching early warning signs before they become a crisis, while pacing the patient’s activity to what the heart can currently tolerate.

Impaired gas exchange. When the lungs congest, oxygen exchange suffers. Positioning that supports easier breathing, monitoring respiratory status and oxygen saturation, and pacing activity to avoid pushing oxygen demand past what the patient can supply are the main levers here.

Excess fluid volume. Heart failure and fluid retention feed each other. This is where dietary sodium and fluid restrictions, daily weight checks, and close monitoring of intake and output matter most, along with helping a patient actually stick to restrictions that are, frankly, unpleasant to live with.

Activity intolerance. The goal isn’t rest for its own sake, it’s finding the level of activity a specific patient can sustain and building from there, alternating activity with rest, monitoring how vital signs respond to exertion, and involving the patient in setting goals they’ll actually follow through on.

Deficient knowledge. A patient who understands their medications, their diet, and their warning signs is a patient far less likely to be readmitted. This is the diagnosis most directly aimed at what happens after discharge, and it’s where patient and family education carries the most long-term weight.

None of these exist in isolation from each other, fluid overload worsens gas exchange, which limits activity tolerance, which affects how well someone can manage their own care at home. That interconnection is, in a sense, the whole point of using a structured process instead of treating each symptom as a separate problem.
