Multivariate Logistic regression model for new arrhythmia and
new tachyarrhythmias.
Multivariate logistic regression models were conducted to explore
variables that were associated with new arrhythmias and new
tachyarrhythmias. As presented in Figure 2, background CHF (OR 4.66, 95
CI 1.45-14.97, p=0.01) and disease severity (p=0.003) were associated
with overall new arrhythmias. A stepwise increase in odds ratio (OR) for
overall new onset arrhythmia was seen with increased disease severity.
As compared with mild disease, patients with moderate, severe and
critical disease had OR of 4.81, 8.86 and 15.79 to develop new
arrhythmia, respectively.
Factors associated with new tachyarrhythmias are presented in Figure 3.
Age, background CHF, presentation with syncope or palpitations and
disease severity were significantly associated with new tachyarrhythmia
in the multivariate analysis.
