Cerebrovascular
disease refers to a group of conditions that affect the circulation of blood to
the brain, which causes limited or no blood flow to the brain. Common forms of cerebrovascular disease
include cerebral thrombosis, cerebral embolism and cerebral hemorrhage. The NWHU monitors trends in hospitalization
and mortality from cerebrovascular diseases in the catchment area.
Hospitalization
Between 2010
and 2014, hospitalization rates for cerebrovascular disease were significantly
higher in the NWHU area than Ontario as a whole. On average, 97.7
hospitalizations per 100,000 per year occurred in Ontario, and 136.7 hospitalizations
per 100,000 per year occurred within the NWHU area, a statistically significant
difference. A downward trend is seen in Ontario, with a slight increase in 2014,
whereas rates in the NWHU area fluctuated with rates increasing in 2012 and
then decreasing in 2013 but rising again in 2014.
Males had
higher rates of hospitalization (152.0 per 100,000 per year) due to
cerebrovascular disease compared with females (122.5 per 100,000 per year) and
the highest rates occurred among those 75 years of age and older (1,298.3 hospitalization
per 100,000).

Mortality
Mortality rates
due to cerebrovascular disease in the NWHU region were level with the province
as a whole between 2007 and 2011. Approximately 36.7 deaths per 100,000 per
year occurred within the NWHU while 30.2 deaths per 100,000 per year occurred
within Ontario during this time period. The rate in the NWHU area was
statistically higher than that of Ontario in 2009, with a large upward spike
seen. However, subsequent years show a consistent downward trend that
ultimately reaches below the Ontario average in 2011.
There were no
statistical differences between male and female rates in the NWHU area. Older Adults
75 years of age and older, as expected, had the highest mortality rates (619.1 deaths
per 100,000).
