3 Risk of CHD Death According to SBP and DBP in MRFIT
4 Systolic blood pressure (SBP) Diastolic blood pressure (DBP) 3 Relative risk of CHD mortality 2 1 Risk of CHD Death According to SBP and DBP in MRFIT With some 350,000 men screened from 1973 to 1975 and followed for major fatal outcomes, the Multiple Risk Factor Intervention Trial (MRFIT) has an enormously powerful database and permits a close look at the relationship of systolic blood pressure (SBP) and diastolic blood pressure (DBP), independently, to coronary heart disease (CHD) mortality risk. During 11.6 years of follow-up, there were 7,150 deaths due to CHD. Compared with subjects in the bottom decile of blood pressure (SBP <112; DBP <71), those at the top decile of the blood pressure distribution (SBP 151; DBP 98) were at markedly increased risk for death from CHD. The relationship of rising blood pressure to risk was continuous and graded, and was steeper for SBP compared with DBP. The average blood pressure levels of the MRFIT cohort were SBP 130 mmHg and DBP 84 mmHg. Optimal SBP, the level with the lowest death rate, was <120 mmHg. Statistical significance between SBP and CHD, and DBP and CHD. SBP: 3rd decile, P<0.05; 4th through 10th deciles, P<0.001. DBP: 4th decile, P<0.01; 5th through 10th deciles, P<0.001.
