Insights

Peripheral artery disease (PAD) affects 12.8% of patients undergoing percutaneous coronary intervention (PCI) for coronary artery disease (CAD). PAD is independently associated with left main and multivessel CAD, suggesting routine ABPI screening for PCI patients.

Area of Science:

  • Cardiology
  • Vascular Medicine

Background:

  • Peripheral artery disease (PAD) is a significant indicator for risk stratification in patients with coronary artery disease (CAD).
  • Understanding PAD prevalence and its correlation with CAD severity is crucial for comprehensive patient management.

Purpose of the Study:

  • To determine the prevalence of PAD in patients with CAD undergoing percutaneous coronary intervention (PCI).
  • To investigate the association between the ankle-brachial pressure index (ABPI) and the severity of CAD.

Main Methods:

  • A cohort of 711 patients undergoing PCI for CAD between August 2009 and August 2011 were analyzed.
  • Peripheral artery disease (PAD) was diagnosed using the ankle-brachial pressure index (ABPI).
  • Coronary artery disease (CAD) severity was assessed using factors including left main disease, multivessel lesions, and SYNTAX score.

Main Results:

  • The prevalence of PAD among patients undergoing PCI for CAD was 12.8%.
  • Patients with PAD exhibited a higher incidence of left main coronary disease (14.3% vs. 5.8%) and multivessel lesions (74.9% vs. 52.1%).
  • Left main CAD and multivessel CAD were independently associated with PAD (OR 2.954 and 2.321, respectively).

Conclusions:

  • The study recommends implementing ABPI-based PAD screening for all patients undergoing PCI for CAD.
  • Screening is particularly important for patients with severe CAD, given the independent association between PAD and complex coronary artery disease.
  • Routine PAD screening can aid in better risk stratification and management of patients with coronary artery disease.

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Peripheral Artery Disease IV: Nursing Management

The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses, temperature changes,...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
