In developing countries, hypertension contributes to cardiovascular disease. A study in Gambia found that 65% of hypertensive patients had left ventricular hypertrophy (LVH), detectable with portable ultrasound.

Area of Science:

  • Cardiology
  • Medical Ultrasound
  • Global Health

Background:

  • Cardiovascular disease (CVD) is a significant health burden in developing nations.
  • Hypertension is a primary driver of CVD, and left ventricular hypertrophy (LVH) is a key risk marker in hypertensive individuals.
  • Effective resource allocation necessitates early identification and management of high-risk patients.

Purpose of the Study:

  • To assess the prevalence of left ventricular hypertrophy (LVH) in a hypertensive population in Gambia using a hand-carried ultrasound (HCU).
  • To evaluate the utility of HCU for diagnosing LVH in resource-limited settings.

Main Methods:

  • A cross-sectional study was conducted in Gambia involving 1,997 participants.
  • Hypertension was identified, and left ventricular hypertrophy (LVH) was diagnosed using a battery-powered hand-carried ultrasound (HCU).

Main Results:

  • Seventeen percent of the examined population had hypertension.
  • Among those with hypertension, 65% exhibited signs of left ventricular hypertrophy (LVH).
  • The HCU successfully identified LVH in this population with limited access to advanced diagnostic tools.

Conclusions:

  • Hand-carried ultrasound (HCU) is a viable tool for detecting left ventricular hypertrophy (LVH) in resource-limited areas.
  • This technology enables the identification of high-risk hypertensive patients, facilitating targeted interventions in developing countries.
  • Utilizing portable diagnostic equipment like HCU can optimize the use of limited healthcare resources for cardiovascular disease management.
