Insights

Low ankle-brachial pressure index (ABPI) correlates with more severe coronary artery disease (CAD). This study found a negative correlation between ABPI and SYNTAX scores in Thai patients undergoing coronary angiography.

Area of Science:

  • Cardiovascular Medicine
  • Vascular Diagnostics
  • Interventional Cardiology

Background:

  • Established correlation between low ankle-brachial pressure index (ABPI) and the presence of coronary artery disease (CAD).
  • Limited research exists on the relationship between ABPI and the severity of CAD, particularly using validated scoring systems.

Purpose of the Study:

  • To investigate the correlation between ABPI and the severity of CAD, as assessed by SYNTAX scores.
  • To evaluate this relationship in a Thai population undergoing coronary angiography (CAG).

Main Methods:

  • Prospective study involving 213 consecutive patients scheduled for CAG.
  • Ankle-brachial pressure index (ABPI) was measured prior to coronary angiography.
  • Coronary artery disease (CAD) severity was quantified using the SYNTAX scoring system.

Main Results:

  • A statistically significant negative correlation was observed between ABPI and SYNTAX scores (correlation coefficient = -0.172, P = 0.01).
  • Lower ABPI values were associated with higher SYNTAX scores, indicating more severe CAD.

Conclusions:

  • Ankle-brachial pressure index (ABPI) demonstrates a negative correlation with the severity of coronary artery disease (CAD).
  • ABPI may serve as a non-invasive indicator for assessing CAD severity in the Thai population.

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...

Sites for measuring blood pressure

Blood pressure measurement is a fundamental clinical procedure, providing crucial data for assessing cardiovascular health. Among the various sites for this measurement, the brachial and popliteal arteries are predominantly utilized due to their accessibility and the reliability of their readings. This lesson delves into the anatomical significance, methodology, and considerations of measuring blood pressure at these locations.

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

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...
