Table 1

Survival of patients according to having an ECG with QRS or ST changes and N-terminal atrial natriuretic peptide (N-ANP) > 0.8 nmol/l or not

  • The p values test the hypothesis that 6.1 year survival in a group equals survival in the age matched reference group with a normal ECG and N-ANP.

  • Survival is shown as actual percentages at 3 years and as Kaplan-Meier (K-M) estimates at 6.1 years.
