number of risk factors associated with stroke =
= SUM(points for all 3 parameters)
Additional factors associated with stroke:
(1) A history of previous stroke was present in 40% of patients who developed a stroke.
(2) No patient with interstitial nephropathy developed stroke.
(3) All patients who developed stroke were hypertensive.
Interpretation
• minimum number of risk factors: 0
• maximum number of risk factors: 3
• The more risk factors that are present the greater the risk for stroke.
• Patients who developed stroke had a high morbidity and mortality. Approximately half of the patients died within 3 months of the stroke.
