Ep. 15 - Understanding Peripheral Artery Disease: Causes, Symptoms, and Preventive Measures

In this episode of Cardiovascular Matters, Dr. Craig Walker and Terry Roberts delve into the critical topic of peripheral artery disease (PAD). They highlight the alarming prevalence of PAD, with an estimated 25 million Americans affected, and emphasize its deadly nature, noting that a person with a new PAD diagnosis is as likely to die of a heart attack as a heart attack survivor.
The discussion underscores the importance of early diagnosis, even in asymptomatic patients, as this presents a valuable opportunity to implement preventive measures and potentially save lives. Dr. Walker explains the various symptoms associated with PAD, ranging from claudication (pain in the muscles during walking) to critical limb ischemia, which can lead to non-healing wounds, ulcers, and even gangrene.
The key risk factors for PAD, such as advanced age, smoking, and diabetes, are explored in depth. The presenters stress the need for healthcare providers to actively screen for PAD, particularly in high-risk populations, through simple techniques like pulse checks and pressure measurements. They also emphasize the importance of a holistic approach, focusing on risk factor modification, including smoking cessation, cholesterol management, and the implementation of walking programs.
~~~~ Key Points Discussed ~~~~

• Prevalence of peripheral artery disease, with an estimated 25 million Americans affected
• Peripheral artery disease as a marker for increased risk of heart attack and stroke
• Importance of early diagnosis, even in asymptomatic patients, to implement preventive measures
• Common symptoms of peripheral artery disease, including claudication, loss of hair on the lower extremities, and critical limb ischemia
• Risk factors for peripheral artery disease, including advanced age, smoking, and diabetes
• Preventive measures, such as smoking cessation, cholesterol management, walking programs, and medication therapy
• Screening techniques, including pulse checks and pressure measurements, to diagnose peripheral artery disease

-----------------------------
The episode also touches on the various medical therapies available, such as the use of aspirin, antiplatelet agents, and the medication salostazole, which can improve blood flow to the legs. Additionally, the discussion highlights the significance of screening for associated conditions, such as coronary artery disease and carotid artery disease, to ensure a comprehensive approach to patient care.
By the end of this informative episode, viewers will have a deeper understanding of the prevalence, symptoms, and preventive measures for peripheral artery disease, empowering them to advocate for their own health and that of their loved ones.
