[Precordial electrocartography (mapping) in cardiac infarct]

Iu Belov, G Urumov, S Popnikolov

    Vutreshni Bolesti
    |January 1, 1978
    PubMed
    Summary

    Precordial electromapping, using sigmaST and nST indices, effectively assesses myocardial hypoxia and tissue damage in ischemic heart disease patients. These methods correlate with creatine phosphokinase levels, offering interchangeable clinical utility.

    Area of Science:

    • Cardiology
    • Medical Imaging
    • Biomedical Engineering

    Context:

    • Ischemic heart disease (IHD) presents a significant global health challenge.
    • Accurate assessment of myocardial infarction extent and tissue viability is crucial for patient management.
    • Current diagnostic methods may require further refinement for real-time evaluation of myocardial injury.

    Purpose:

    • To evaluate the efficacy of precordial electromapping in quantifying myocardial hypoxia and tissue damage in patients with ischemic heart disease.
    • To correlate precordial electromapping indices (sigmaST and nST) with biochemical markers of myocardial injury, specifically creatine phosphokinase (CPK).
    • To determine the practical interchangeability of sigmaST and nST indices in clinical settings.

    Summary:

    • This study involved precordial electromapping of 34 ischemic heart disease patients, registering 30 points on the chest.
    • Key indices, sigmaST (ST segment elevation sum) and nST (points with ST elevation >0.1 mV), were analyzed.
    • Both indices demonstrated a strong correlation with blood creatine phosphokinase levels measured 24 hours post-examination, indicating their reliability in reflecting myocardial hypoxia and tissue damage.

    Impact:

    • Precordial electromapping provides a non-invasive method to assess the severity of myocardial infarction.
    • The sigmaST and nST indices are interchangeable and correlate well with established biomarkers, aiding clinical decision-making.
    • This technique offers valuable insights into the extent of myocardial hypoxia and disturbed biological activity in affected cardiac tissues.
