BACKGROUND: Ischemic events commonly occur in the morning hours. This is retrospective study of association between morning blood pressure surge and ischemic events in hypertensive patients.

METHOD: A descriptive analysis of patients diagnosed with cerebrovascular disease who presented in the Emergency Department of Pasig City General Hospital with elevated blood pressure of 140/90 and above (either known hypertensive or newly diagnosed), between 12 midnight and 12 noon from January to June 2009.

CONCLUSION: Incidence of stroke is higher among males and it increases advancing age. It is highest in women 65 years old and above. Analysis showed that higher blood pressure in the morning implicated with higher incidence of stroke with peak occurrence between 8 and 11 in the morning. There is lack of association between circadian rhythm and the timing and type of stroke.
