Blood pressure, stroke, and coronary heart disease: Part 1, prolonged differences in blood pressure: prospective observational studies corrected for the regression dilution bias
The associations of  diastolic blood pressure ( DBP )  with  stroke  and with coronary heart disease ( CHD ) were investigated in nine major prospect i ve observational studies : total 420,000 individuals , 843 strokes , and 4856 CHD events , 6 - 25 ( mean 10 ) years of follow-up . The combined results demonstrate positive , continuous , and apparently independent associations , with no significant heterogeneity of effect among different studies . Within the range of DBP studied ( about 70 - 110 mm Hg ) , there was no evidence of any " threshold " below which lower levels of DBP were not associated with lower risks of stroke and of CHD . Previous analyses have described the uncorrected associations of DBP measured just at " baseline " with subsequent disease rates . But , because of the diluting effects of r and om fluctuations in DBP , these substantially underestimate the true associations of the usual DBP ( ie , an individual 's long-term average DBP ) with disease . After correction for this " regression dilution " bias , prolonged differences in usual DBP of 5 , 7.5 , and 10 mm Hg were respectively associated with at least 34 % , 46 % , and 56 % less stroke and at least 21 % , 29 % , and 37 % less CHD . These associations are about 60 % greater than in previous uncorrected analyses . ( This regression dilution bias is quite general , so analogous corrections to the relations of cholesterol to CHD or of various other risk factors to CHD or to other diseases would likewise increase their estimated strengths . ) The DBP results suggest that for the large majority of individuals , whether conventionally " hypertensive " or " normotensive " , a lower blood pressure should eventually confer a lower risk of vascular disease
