Prevalence of signs and symptoms of heart failure (SSHF) and left ventricular dysfunction (LVSD)

  • Part I shows observed prevalence figures from the cross sectional survey. Heart disease refers to combined suspected and definite heart disease. Part II shows the number of patients with LVSD (n LVSD) among those examined (n examined) in groups 2 to 4. Column i shows the mean and standard deviation (SD) of left ventricular ejection fraction (LVEF) in each group. Part III shows the calculated prevalence of LVSD at ⩾ 50 years by multiplying figures from parts I and II.

  • 3-150 Total of groups 3 and 4;

  • 3-151 Total of groups 2 to 4. CL, confidence limits. yo, years old
