Abstract

Purpose: To determine the association of changes in blood pressure (BP) components between baseline examination (1999–2001) and a second visit (2002–2005) with incident cardiovascular diseases (CVD). Methods: In 3569 (2048 female) Iranian subjects ≥30 y, systolic BP, diastolic BP, mean arterial pressure (MAP) and pulse pressure (PP) were evaluated in two consecutive visits. Subjects were then followed for cardiovascular events. Multivariate sex-adjusted Cox Proportional-Hazards models were built for each BP component’s change, and further adjusted for baseline BP values, traditional cardiovascular risk factors, and their changes. Results: During a median follow-up of 6.09 years after the second examination, 303 CVD cases occurred. A 1 SD increase in systolic BP, diastolic BP and MAP were significantly associated with 21%, 22%, and 95% increased CVD risk after adjustments for baseline values of BP components and other common risk factors (all p-values

Abstract

Purpose:To determine the association of changes in blood pressure (BP) components between baseline examination (1999–2001) and a second visit (2002–2005) with incident cardiovascular diseases (CVD). Methods:In 3569 (2048 female) Iranian subjects ≥30 y, systolic BP, diastolic BP, mean arterial pressure (MAP) and pulse pressure (PP) were evaluated in two consecutive visits. Subjects were then followed for cardiovascular events. Multivariate sex-adjusted Cox Proportional-Hazards models were built for each BP component’s change, and further adjusted for baseline BP values, traditional cardiovascular risk factors, and their changes. Results:During a median follow-up of 6.09 years after the second examination, 303 CVD cases occurred. A 1 SD increase in systolic BP, diastolic BP and MAP were significantly associated with 21%, 22%, and 95% increased CVD risk after adjustments for baseline values of BP components and other common risk factors (allp-values <0.05). Importantly, diastolic BP change resisted after further adjustment with systolic BP change (hazard ratio 1.21, CI 95% 1.05–1.39). PP change showed no significant association with CVD. Conclusions:In a middle-aged population, three-year rises in systolic BP, diastolic BP, MAP, but not PP were associated with increased incident CVD. The significant association between diastolic BP change and CVD was shown independent of systolic BP change. [ABSTRACT FROM AUTHOR]

Abstract

To determine whether there are differences between blood pressure (BP) measured by the nurse (NBP), BP measured by the physician (PBP) and self-measured BP in treated hypertensive patients and, if found, to evaluate their clinical importance.An observational study is carried out with hypertensive patients recruited from two village-based community health centres in Catalonia (Spain) serving an area with a total population of 2800 inhabitants. All patients treated for hypertension visiting the health centre on a specific day of the week and during the same timetable between October 2000 and May 2001 were included.The difference between physician-systolic BP and nurse-systolic BP was 5.16 mmHg (95% CI 2.62-7.7; p0.001). The difference between physician-systolic BP and self-measured systolic BP was 4.67 mmHg (95% CI 0.89-8.44; p=0.016). The differences between nurse-systolic BP and self-measured systolic BP were not significant (0.49 mmHg; 95% CI 3.71-2.71; p=0.758). With regards to diastolic BP, no significant differences were found between the different ways of measurement. NBP gave the following values: sensitivity (Sn) of 92% and specificity (Sp) of 60%; positive predictive value (PPV) of 65.7% and negative predictive value (NPV) of 90% with a positive coefficient of probability (CP+) of 2.3 and a negative coefficient of probability (CP-) of 0.133. PBP gave the following results: Sn=72%; Sp=66.7%; PPV=64.3%; NPV=74.1%; CP+=2.16 and CP- = 0.420.Systolic BP measured by the nurse in treated hypertensive patients is significantly lower than the readings obtained by the physician, and are almost identical to ambulatory BP monitoring. Blood pressure determination by the nurse is desirable not only for diagnosis but also to evaluate the level of control of blood pressure during the follow-up of treated hypertensive patients.
