When do strokes and heart attacks occur?

"Results of a population-based study show a higher incidence of stroke in men older than 75 years and in women older than 65 years. This is in contrast to a higher incidence of acute myocardial infarction observed in men younger than 55 years."

"Case fatality rates at 30 days were similar for stroke and acute myocardial infarction (9.80% and 9.84%, respectively). "

"For stroke patients, independent factors associated with higher case fatality rates at 30 days included age 85 years and older, cardioembolic and hemorrhagic strokes, the first study period (2001 to 2002), history of acute myocardial infarction, and glycemia greater than 7.8 mmol/L. Hypertension (p < 0.001) was more frequent in stroke patients."

"For acute myocardial infarction patients, independent factors included age >85 years at onset, the first study period (2001 to 2002), history of hypercholesterolemia, diabetes, tobacco consumption, and glycemia at onset greater than 7.8 mmol/L. The prevalence of male sex (p < 0.001), hypercholesterolemia (p = 0.002), and diabetes (p = 0.004) was greater in acute myocardial infarction patients."
