The rates of morbidity due to IHD are difficult to obtain. According to the 1996-97 survey done by the National Population Health Survey (NPHS), overall 4% of Canadian women who replied to the survey indicated that they have been diagnosed with heart disease with increasing rates by age. As a result, in the age group of 75 and over, 22% of women responded to have been diagnosed heart disease.
In Canada, heart disease and stroke are the leading causes of hospitalization for men and women, not including childbirth in women. Hospital admissions due to CVD represented 13% of all hospitalization for Canadian women in 1996-97, with higher rates for increasing age. From these admissions, IHD represented a large portion. In the past three decades, there has been an increase in the number of IHD that have been recorded and this trend is expected to increase over the next two decades. While hospitalization for heart failure and IHD are more frequent in elderly women (75 years and more), admissions for IHD has become more prominent a health problem in women aged 55 years and more. Currently, men are more frequently hospitalized for IHD compared to women, however, the hospital stay amongst women is more likely to surpass that of men.
