The Heart Foundation of Jamaica

Area of Science:

  • Cardiology
  • Public Health
  • Epidemiology

Background:

  • Hypertension is prevalent in Jamaica, affecting 71% of women and 47% of men.
  • A significant portion (13%) of detected hypertension cases were newly diagnosed.
  • Obesity is highly prevalent in women (80%), posing a public health challenge.

Purpose of the Study:

  • To analyze the findings of the Heart Foundation of Jamaica's screening program.
  • To assess the prevalence of hypertension, left ventricular hypertrophy, and ischemic changes.
  • To evaluate arrhythmia patterns and identify key risk factors and diagnostic needs.

Main Methods:

  • Analysis of data from a hypertension screening program.
  • Review of electrocardiographic (ECG) findings over a two-year period for 14,739 patients.

Related Experiment Videos

  • Long-term observation of arrhythmia prevalence over 15 years.

    • Main Results:

    • Hypertension detected in 71% of women and 47% of men, with 13% new diagnoses.
    • Left ventricular hypertrophy found in 18% of hypertensive women and 27% of men.
    • Ischemic ECG changes were low (4%), but uncontrolled atrial fibrillation was noted in hypertensive patients.

    Conclusions:

    • Inadequate blood pressure control is common, and left ventricular hypertrophy is frequent in hypertensive patients.
    • ECG screening is crucial for 'silent' ischemia in diabetics and left ventricular hypertrophy in hypertensives.
    • Public education on obesity and regular ECG monitoring are recommended for at-risk populations.
