LOS ANGELES – Although recent findings from circumscribed patient populations enrolled in intervention studies have shown improved survival rates in patients with a recent intracerebral hemorrhagic stroke, data from a large, observational study in the Netherlands suggested a much darker real-world picture, with a 6-month mortality of 64% identified in a total cohort of nearly 15,000 people followed prospectively starting in 1990.
In striking contrast to the survival pattern over time of patients in the same Dutch study who had a first acute ischemic stroke, which showed a statistically significant and meaningful cut in mortality for ischemic stroke patients during the 25-year period examined, survival rates for patients during the first months following a first intracerebral hemorrhage (ICH) stayed flat during 1991-2015, Reem Waziry, MD, said at the International Stroke Conference sponsored by the American Heart Association.
“The promising treatment advances [applied to patients] in the recent ICH trials may not be reflected in community-based treatment,” suggested Dr. Waziry, a research and teaching fellow in clinical epidemiology at the Harvard School of Public Health in Boston.
The data she reported came from the Rotterdam Study, which followed unselected, older people in the Rotterdam community with no stroke history, and during 25 years of monitoring identified 162 incident ICH strokes and 988 acute ischemic strokes. Concurrently with Dr. Waziry’s talk at the conference, the data she reported were published in Stroke. The data she reported also showed that, during the 25 years studied, mortality at 3 years following a first ICH stroke rose to 73% on average.
During her talk, Dr. Waziry also presented an unpublished comparison of the 64% 6-month mortality in the Rotterdam Study with the 3- to 6-month mortality reported in the control arms of four recent, randomized intervention trials, including the MISTIE III trial. Among the four randomized trials Dr. Waziry selected to make this post-hoc comparison, the study with the highest mortality among control patients was MISTIE III, which showed about 25% mortality after 6 months. In contrast, the 19% 6-month mortality among ischemic stroke patients in the Rotterdam Study was roughly similar to the mortality seem in the control arms of some recent studies of interventions for patients with acute ischemic stroke.
The Rotterdam Study receives no commercial funding. Dr. Waziry had no disclosures.
