![]() ![]() Event-free survival rates for the different HFSS and SHFM risk strata were determined using the Kaplan–Meier method and compared by log-rank test ( Figure 2). Pearson's correlations were calculated between the HFSS and SHFM ( Figure 1A) and also between the peak VO 2 alone and the SHFM ( Figure 1B) (but not between the peak VO 2 and the HFSS, because the peak VO 2 is a heavily weighted component of the HFSS). īaseline characteristics for patients with and without events were compared by chi-square tests (categorical variables) and unpaired t-tests (continuous variables) ( Table 1). The 7 products were summed and the absolute value determined according to the following equation: HFSS =. Each variable for the continuous and dichotomous variables was multiplied by a model coefficient, derived from a proportional hazard model. The HFSS was derived in each patient from the 7 clinical parameters. Dichotomous variables were coded as: 1 = present and 0 = absent. The presence of IVCD was defined as QRS interval of ≥ 120 milliseconds due to left or right bundle branch block, non-specific intraventricular conduction delay or ventricular-paced rhythm. LVEF was determined using echocardiography or contrast/radionuclide ventriculography. Peak VO 2 was determined during maximal treadmill exercise using a modified Naughton protocol and a metabolic cart (Medical Graphics, Minneapolis, MN). The HFSS includes 7 parameters: resting heart rate (HR) mean blood pressure (mBP) left ventricular ejection fraction (LVEF) serum sodium presence or absence of ischemic heart disease presence or absence of intraventricular conduction defect (IVCD) and peak VO 2. ![]() One or more continuous variable was missing in 272 patients. Missing continuous data for the SHFM data were imputed as the mean for all patients.
