Electrocardiographic left ventricular hypertrophy (LVH) with strain pattern in hypertensive Nigerians is linked to increased left ventricular mass and abnormal geometry. This ECG finding signifies a higher risk of adverse cardiac remodeling compared to other LVH indicators.

Area of Science:

  • Cardiology
  • Medical Imaging
  • Hypertension Research

Background:

  • Electrocardiographic left ventricular hypertrophy (LVH) with a strain pattern is a recognized marker for LVH.
  • The presence of ECG-LVH strain pattern in hypertensive patients indicates a poor prognosis.
  • Hypertension is a major risk factor for cardiovascular disease, including LVH.

Purpose of the Study:

  • To assess the association between electrocardiographic strain pattern and left ventricular mass (LVM) and function.
  • To compare these associations in hypertensive Nigerians with different ECG criteria for LVH.
  • To investigate the prognostic implications of ECG-LVH strain pattern in this population.

Main Methods:

  • Electrocardiograms (ECG) and echocardiograms were performed on hypertensive patients.

  • Study groups included patients with ECG-LVH and strain pattern, ECG-LVH by Sokolow-Lyon criteria, and normal controls.
  • A total of 191 participants (64, 65, and 62 respectively) were analyzed.

    • Main Results:

    • The ECG strain pattern was associated with a dilated left atrium.
    • Patients with ECG strain pattern exhibited larger left ventricular internal dimensions.
    • Greater absolute and indexed LVM were observed in hypertensive Nigerians with ECG strain pattern compared to other groups.

    Conclusions:

    • The ECG strain pattern is associated with increased left ventricular mass (LVM).
    • This ECG finding signifies an elevated risk of developing abnormal left ventricular geometry.
    • The study supports the clinical utility of ECG strain pattern in risk stratification for hypertensive patients.
