“…However, in recent decades the ISH prevalence has also increased in young adults due to the epidemic of overweight and obesity [ 10 , 11 ]. The prevalence of ISH has been reported different from 6.51 to 35%, which depend on the definition of ISH and distribution of age, sex, race and other variables in the studied populations [ 9 , 12 – 15 ]. It has shown that systolic blood pressure plays a greater role in cardiovascular disease than diastolic blood pressure [ 16 ].…”

Background Isolated systolic hypertension (ISH), is the most common form of hypertension in older adults. However, the ISH prevalence is not well known in many developing countries such as Iran. This study was conducted to determine the ISH prevalence and its related risk factors in an Iranian population. Methods Data were obtained from the second phase of the Shahroud eye cohort study (ShECS) in 2014. ShECS is a longitudinal population-based study which the first phase had been conducted in 2009 using the stratified multistage cluster sampling design on 5190 people aged 40 to 70 years. The ISH prevalence was determined based on the eighth Joint National Commission guidelines for different demographic variables. The associated risk factors were estimated by multiple logistic regression and a two-tailed p-value less than 0.05 was considered significant. Results The ISH prevalence was 15.89% (95% CI: 14.88–16.96). It was 15.68% (14.12–17.39) and 15.87% (14.54–17.29) for men and women, respectively. The prevalence of ISH increased significantly with increasing age. The 65–70 compared to 45–69 year age group (OR = 4.21), body mass index (OR = 1.03), diabetes (OR = 1.64), retirement, compared to practitioner job (OR = 1.53), and waist to hip ratio (WHR) (OR = 9.81) were significantly associated with ISH prevalence. Conclusions ISH is highly prevalent among the older adult population in Iran. Given the risk of cardiovascular disease associated with ISH, it is recommended to conduct education and public health interventions to improve the detection, prevention, and treatment of ISH.

“…When using brachial BP only for the evaluation of therapeutic effi cacy of current patient antihypertensive medication, we may omit the central systolic hypertension, which has deleterious effect on heart, brain, kidneys and arteries. Brachial blood pressure may overestimate the control of hypertension (25,26). Patients may suffer from unrecognized hypertension with all negative consequences.…”

“…Prevailing central systolic or brachial systolic BP in individual patient can be expressed also by cSBP/brachSBP ratio; the value above 1.0 expresses a higher central systolic BP; value below 1.0 expresses a higher brachSBP. The prevalence of central systolic hypertension is very frequent in isolated systolic hypertension (ISH) and is frequently associated with a central obesity (26).…”

OBJECTIVES: Higher CSBP than brachial SBP in individual patient increases cardiovascular (CV) risk. For follow-up it is important to assess the reproducibility of such measurements. The aim of this study was to assess the reproducibility of these differences, expressed as a CSBP/BrachSBP ratios. SUBJECTS AND METHODS: Eighty-three patients on antihypertensive therapy were analysed for the reproducibility of such ratios after time interval of several month up to several years. For CSBP estimation, we used the Arteriograph (Tensiomed Ltd.), based on blood pressure measurements by cuff on oscillometric principle, using pulse wave analysis (PWA) for assessment of CSBP. RESULTS: The proportion of patients retained the same characteristics (either higher central or higher peripheral SBP) between the fi rst and second measurement was 71.1 %. The association between 1st and 2nd measurement, was statistically signifi cant, p < 0.001. CONCLUSION: In our study, a high proportion (60 %) of treated hypertensive patients had CSBP higher than brachial SBP, which may adversely infl uence their prognosis. This characteristic is highly reproducible. Taking into the account these differences may increase the exactness of CV risk estimation and may contribute to explanation of residual risk of individual patient (Tab.

“…In a recent study from Taiwan among drug naïve adults ≥19 years, the prevalence rates of ISH and IDH were 6.51% and 1.92%, respectively. [ 6 ] According to the National Health and Nutrition Examination Survey (1999–2010), the prevalence of untreated ISH was 9.3% in the United States of America. [ 7 ] Most studies in India have been restricted to the district population, and the prevalence estimates for ISH vary between 4.3%[ 8 ] to 13.3%.…”

Background: Isolated Systolic Hypertension (ISH) and Isolated Diastolic Hypertension (IDH) are often the ignored forms of hypertension and are determinants of future cardiac and neurological events and contribute to mortality. However, the nationally representative estimates of both these forms of hypertension remain unknown from India. Aim: To estimate the ISH and IDH from a nationally representative survey of India. Material and Methods: The present study used data from 7,23,181 people (15–54 years), recorded during the fourth round (2015–2016) of the National Family Health Survey (NFHS), India. The prevalence of ISH and IDH was calculated for state comparison, while multilevel logistic regression analysis was done to assess the correlates of both types of hypertension. Results: The prevalence of ISH and IDH was found to be 1.2% (95% CI 1.0–1.4) and 5.7% (95% CI 5.2–6.2), respectively. The prevalence of both ISH and IDH increased with age, with a more significant increase in systolic pressure towards the higher age. Northeastern states of India (Assam, Meghalaya, and Arunachal Pradesh) had the highest prevalence of both forms of hypertension. On multilevel logistic regression, male gender, increasing age groups (highest odds ratio (OR) being in 45–49 year age group), alcohol, and diabetes positively predicted both ISH and IDH. Urban residence, literacy, and tobacco were positive predictors of IDH, whereas urban residence, smoking, and literacy negatively predicted ISH. Conclusion: ISH and IDH have a significant presence among the population of India. This data provides insights to formulate strategies at the primary and primordial prevention levels.
