Effect of Concomitant Medical Conditions at the
Time of Stroke on Long-Term Survival
In the Lehigh Recurrent Stroke study, 662 patients
who survived at least 30 days after onset of an initial stroke
were followed to determine how the presence of risk factors
at baseline (i.e., at the time of the initial stroke) influenced
survival over the subsequent 42 months. Compared with
patients of the same age, sex, number of neurological deficits,
and comorbidities, cumulative survival rates (Kaplan-Meier
estimates) were lower among those with myocardial infarction
(left), cardiac arrhythmia (center), and diabetes mellitus
(right). Hazard ratios were 1.7 (p=0.006), 1.5 (p =
0.023), and 1.4 (p = 0.059), respectively. Hypertension
and transient ischemic attacks were not significantly associated
with increased mortality.
