In the medical community, peripheral arterial disease (PAD) is known as a ‘silent killer,’ going undiagnosed for years as it gradually constricts arteries and, with it, the vital flow of blood to the limbs. For over 12 million across the country and 200 million worldwide, PAD represents more than a chronic illness. PAD is a constant struggle that turns routine activities into formidable and often painful obstacles.
In this article, we review the multifaceted impact of PAD on quality of life, from the physical restrictions to the social consequences at various stages of the disease. We also discuss holistic, patient-centered treatment options that address both medical and personal dimensions of living with PAD.
Quality of Life With Early Stage PAD
In the initial stages of PAD, blood is still able to reach the limbs at rest. However, it is insufficient for higher-demand activities. Therefore, patients may experience muscle pain or cramping in the legs, hips, or buttocks during brisk walking and climbing stairs.
This condition, known as intermittent claudication, is often misdiagnosed as general muscle fatigue or aging-related discomfort. Regardless of the diagnosis, it can be frustrating for patients as it limits their mobility and ability to engage in physical activities.
While most patients can still carry on with daily tasks, those that involve walking or standing for a prolonged period become more challenging. To avoid the pain, patients often opt for more sedentary alternatives, for example, taking the elevator instead of climbing stairs. This leads to decreased overall fitness and potential weight gain.
For those who have been diagnosed with PAD, these limitations can lead to anxiety and depression as they might worry about their future health and the potential progression of the disease.
Quality of Life in Moderate Stages of PAD
As PAD progresses, the symptoms become more severe and persistent. Pain begins to occur even at rest, further decreasing mobility. Patients typically need more assistance in daily activities as they start to struggle with basic tasks such as dressing, bathing, and cooking. The issues can lead to significant frustration.
As PAD continues to damage and block arteries, patients may develop chronic wounds known as arterial ulcers or sores in their feet, ankles, and legs. Due to the poor circulation, these wounds take substantially longer to heal, upwards of 30 days, significantly increasing the risk of infection.
The relentless pain may also lead to sleep disturbances and constant discomfort, affecting overall health and well-being. The sight of slow-healing wounds may also exacerbate feelings of anxiety and depression. One can see how this often becomes a cyclical, difficult pattern as PAD progresses.
Quality of Life With Late-Stage PAD
In advanced stages, arteries are severely constricted, and blood flow is extremely poor. Physically, the pain is now constant and debilitating, particularly at night. Consequently, mobility is severely restricted. Many patients are unable to walk unassisted and may become bedridden.
The lack of adequate blood flow also leads to irreversible tissue death and, eventually, gangrene. The skin turns greenish-black and requires immediate surgical interventions, such as debridement or amputation.
Psychologically, the chronic, intense pain and the looming threat of limb loss can lead to profound hopelessness. The loss of independence as patients become highly dependent on caregivers adds to the emotional distress. This can give rise to feelings of inadequacy that festers further.
For patients with late-stage PAD, the need for constant care and far more frequent hospitalizations considerably deteriorates their quality of life. Additionally, the costs of ongoing medical treatments, possible surgeries, and long-term care can be a major financial burden, increasing stress for both patients and their families.
Managing Quality of Life in Peripheral Arterial Disease
To minimize the toll of the challenges, there are several strategies that lower the need for major surgery and improve life for those with PAD. These interventions include medications, hyperbaric oxygen therapy, wound care, and lifestyle modifications.
Medications
There are several classes of drugs used in combination to improve blood flow and alleviate the symptoms of PAD. These include:
- Antiplatelet agents: These drugs improve blood flow by preventing blood clots from forming. This also reduces the risk of heart attacks and stroke.
- Statins: Statins lower cholesterol levels, which help slow the progression of PAD.
- ACE Inhibitors: These drugs relax blood vessels, which helps control blood pressure and enhance blood flow.
Hyperbaric Oxygen Therapy (HBOT)
In hyperbaric oxygen therapy, patients breathe pure oxygen inside a pressurized room or chamber. These conditions improve oxygenation in the body and reduce tissue hypoxia.
For those with PAD, HBOT can help reduce pain and, in turn, increase mobility. Moreover, as HBOT enhances oxygen delivery to the damaged tissues, it reduces inflammation and promotes cell repair, helping patients with slow-healing ulcers and sores.
Wound Care
Proper and regular wound cleaning and dressing reduces the likelihood of infection, crucial for PAD patients suffering from compromised blood flow. Effective wound management also minimizes pain and discomfort, allowing patients to take part in daily activities with greater ease.
Lifestyle Modifications
Making lifestyle changes is a crucial part of PAD management and can greatly slow down its progression. Reports show that up to 80% of patients with PAD are current or former smokers, which is why quitting smoking is particularly important. Smoking constricts blood vessels, reducing oxygen supply to tissues even more. Other modifications include:
- Reducing weight to a healthy range
- Maintaining a healthy diet low in cholesterol and saturated fats
- Reducing alcohol intake
- Engaging in regular physical activity, even light exercises like walking
- Wearing compression stockings and wraps
