Systolic blood pressure, isolated systolic hypertension and risk of coronary heart disease, strokes, cardiovascular disease and all-cause mortality in the middle-aged population.
ABSTRACT To determine the risk of death from coronary heart disease, stroke, all cardiovascular disease and all-cause mortality associated with systolic blood pressure and in particular with isolated systolic hypertension among the middle-aged population.
A prospective 15-year cohort study of two independent cross-sectional random samples of subjects participating in baseline surveys in 1972 and 1977. Each survey included a self-administered questionnaire, measurements of height, weight and blood pressure and the determination of the serum cholesterol concentration.
North Karelia and Kuopio provinces in eastern Finland. Mortality follow-up complete with the personal identification number.
Participants were 10,333 men and 11,160 women aged 25-64 years without histories of myocardial infarction and stroke incidence at the time of the baseline survey. Isolated systolic hypertension in these analyses was defined as systolic blood pressure > or = 160 mmHg and diastolic blood pressure < 95 mmHg. Subjects with blood pressure < 160/90 mmHg were considered normotensive.
Coronary heart disease, stroke, cardiovascular disease and all-cause mortality among men and women aged 45-64 years increased with the increasing systolic blood pressure. Among women aged 45-64 years, isolated systolic hypertension increased the relative risk of these fatal events. Among men aged 45-64 years, only coronary heart disease mortality was significantly associated with isolated systolic hypertension.
Isolated systolic hypertension is an important predictor of death from coronary heart disease, stroke, cardiovascular disease and all causes for women. For men aged 45-64 years, the risk of death from coronary heart disease was associated with isolated systolic hypertension, but the risk of stroke, cardiovascular disease and all-cause mortality associated with increasing systolic blood pressure was evident already at the systolic blood pressure levels < 160 mmHg, independently of the level of diastolic blood pressure.

ABSTRACT: In a community survey, 4432 persons aged 15 years and older in two districts in Uganda were studied. Blood pressure was measured and predictors for subtypes of uncontrolled hypertension (HTN) were assessed using bivariate and multivariate logistic regression modeling. Prevalence of uncontrolled HTN was 20.2% and the subgroups of isolated systolic HTN (ISH), isolated diastolic HTN (IDH), and systolic-diastolic HTN (SDH) were 7.2%, 4.2%, and 8.8%, respectively. No difference was observed between the sexes. For all HTN subtypes, middle (35–49 years) and older age (50+) groups had a higher prevalence compared with younger subjects (15–34 years) (all P<.001). IDH prevalence in older age was not higher compared with younger age (P=.417). After multivariate analysis, middle age predicted all subtypes of HTN and old age predicted ISH and SDH. Alcohol consumption predicted IDH and SDH. Uncontrolled HTN in this population increases in the order IDH, ISH, and SDH, with more than 1 in 5 having uncontrolled HTN.Journal of Clinical Hypertension 07/2014; 17(1).

ABSTRACT: Systemic hypertension (HT) is a major long-term complication even after successful repair of aortic coarctation (CoA), and many factors are involved in this pathophysiology.10/2014; 5(4):546-53. DOI:10.1177/2150135114551028
