Insights

Peripheral vascular disease (PVD) is common in coronary artery bypass grafting (CABG) patients and predicts some morbidity. However, PVD appears to have limited impact on short- to middle-term outcomes after CABG surgery.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Medicine
  • Clinical Risk Assessment

Background:

  • Objective risk assessment is vital in cardiac surgery.
  • Peripheral vascular disease (PVD) is a common comorbidity in patients undergoing coronary artery bypass grafting (CABG).

Purpose of the Study:

  • To evaluate the impact of PVD on morbidity, mortality, and overall outcomes in CABG patients.
  • To determine the predictive value of the ankle-brachial pressure index (ABPI) for risk stratification in CABG.

Main Methods:

  • The ankle-brachial pressure index (ABPI) was used to diagnose PVD in 178 CABG patients.
  • Patients were categorized into normal (ABPI 0.9-1.3) and low (ABPI < 0.9) groups.
  • Follow-up was conducted over a mean period of 26 months.

Main Results:

  • PVD was present in 20.5% of CABG patients, associated with older age, female sex, higher risk scores, and intermittent claudication.
  • PVD significantly predicted atrial fibrillation and showed a trend towards predicting postoperative myocardial infarction.
  • Patients with PVD exhibited higher rates of specific morbidities.

Conclusions:

  • PVD is prevalent in CABG patients and increases with age.
  • While PVD predicts certain morbidities, its influence on short- and middle-term CABG outcomes is limited.
  • The ABPI may have restricted utility in identifying high-risk CABG patients.

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

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...
