39 Stroke is now more common than myocardial infarction in arterial hypertension Meta-analysis of drug trials in 1990 reported 773 strokes and 1442 heart attacks in 37,000 patients. In trials since 1990 in 59,650 patients there were 2233 strokes and 1627 heart attacks. If the Oriental trials are excluded, there were 2507 strokes and 1603 heart attacks. This trend was seen in both middle-aged and elderly trial participants. The reasons for this apparent change are unknown. Kjeldsen et al, Blood Pressure 2001;10:190-2
