Isolated systolic hypertension and insulin resistance assessment tools in young and middle-aged Chinese men with normal fasting glucose: a cross-sectional study

The vital role of insulin resistance (IR) in the pathogenesis of isolated systolic hypertension (ISH) has been expounded at the theoretical level. However, research on the correlation between some specific IR indicators and ISH is still rare, especially at different glycemic statuses. We conducted this study to explore the association between three IR indicators and ISH among young and middle-aged adults with normal fasting plasma glucose (NFG). This large cross-sectional study included 8246 young and middle-aged men with NFG and diastolic blood pressure < 90 mmHg. The homeostasis model assessment for IR (HOMA-IR) index, triglyceride glucose (TyG) index, and the metabolic score for IR (METS-IR) were calculated with the corresponding formula. The proportions of ISH among young and middle-aged men were 6.7% and 4.4%, respectively. After fully adjusting, only HOMA-IR rather than TyG and METS-IR was significantly associated with ISH. Moreover, fully adjusted smooth curve fitting showed that the association between HOMA-IR and ISH were approximately linear in both two age groups (P for non-linearity were 0.047 and 0.430 in young and middle-aged men, respectively). Among young and middle-aged men with NFG, using HOMA-IR instead of noninsulin-dependent IR indicators may have advantages in the hierarchical management of ISH. Further longitudinal research may be needed to determine their potential causal relationship.

Stroke prevalence among isolated systolic hypertension subjects in Indonesia

IntroductionHypertension has been known to be a decisive factor for stroke in the elderly; however, limited studies reported stroke risk factors in subjects with isolated systolic hypertension (ISH).MethodsThis cross-sectional survey was conducted using Riskesdas 2018 secondary data. Subjects aged 55 years who had a systolic blood pressure ≥140 mmHg and diastolic < 90 mmHg were included as the study sample. According to the National Institute of Health Research and Development, the Ministry of Health, Republic of Indonesia, all study variables were measured using household and individual questionnaires. The data were analyzed using the chi-square test and Fisher’s test.ResultsOf 3159 subjects with ISH 8.3% had a stroke, the risk factors that had a significant relationship with the prevalence of stroke (p<0.005) were gender (1,790; 1,420-2,256), smoking habits (1,645; 1,291-2,096), physical and mental stress (2,080; 1,618-2,673), area of residence (1,720; 1,331-2222), and education level (0.656; 0.515-0.835).ConclusionPrevalence of stroke among ISH in Indonesia was 8.3%. Female with smoking habits, had mental and physical stress, liviing in urban area, and had low level eduatcion were associated with the status of stroke in ISH subjects in Indonesia.

Cardiovascular mortality risk in young adults with isolated systolic hypertension: findings from population-based MONICA/KORA cohort study

The clinical significance of isolated systolic hypertension in young adults (ISHY) remains a topic of debate due to evidence ISHY could be a spurious condition resulting from exageratted pulse pressure amplification in “young tall men with elastic arteries”. Hence, we aimed to investigate whether ISHY is associated with an increased risk of cardivascular (CVD) mortality in a sample of 5597 young adults (49.8% men, 50.2% women) between 25 and 45 years old from the prospective population-based MONICA/KORA cohort. ISHY was prevalent in 5.2% of the population, affecting mostly men (73.1%), and associated with increased smoking, obesity, and hypercholesterolemia in comparison to participants with normal blood pressure (BP). Within a follow-up period of 25.3 years (SD ± 5.2; 141,768 person–years), 133(2.4%) CVD mortality cases were observed. Participants with ISHY had a hazard ratio (HR) of 1.89(1.01–3.53, p < 0.05) times higher risk of CVD mortality than participants with normal BP, even following adjustment for CVD risk factors. However, adjustment for antihypertensive medication (HR 0.46; 0.26–0.81, p < 0.001) and increasing height (HR 0.96; 0.93–0.99, p < 0.05) revealed independently protective effects against CVD mortality, suggesting that although ISHY is associated with an increased risk of CVD mortality, the protective effects of increasing height or antihypertensive medication should be considered in treatment rationale.

Arterial hypertension + past stroke – a case report

Arterial hypertension, as a very widespread chronic disease, and thus differing in both pathomechanism and course in patients, requires a significant individualization of pharmacotherapy. One such special group is the elderly. Both the low-renin pathomechanism of arterial hypertension and its phenotype (isolated systolic hypertension) imply the choice of a specific pharmacotherapy. Additionally, in this group, side effects should be observed much more vigilantly, while target blood pressure values should be treated more liberally. An example of antihypertensive therapy in a patient belonging to the group described is presented in the following case.

Risk of Atrial Fibrillation in Young Adults With Isolated Diastolic, Isolated Systolic, and Systolic-Diastolic Hypertension

There is limited evidence regarding the risks of incident atrial fibrillation (AF) associated with stage 1 isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), and systolic-diastolic hypertension (SDH), especially among young adults. We aimed to evaluate the association between early stage of hypertension and AF in young adults. From the Korean nationwide health screening database, 2 958 544 subjects aged 20 to 39 years who were not prescribed antihypertensive medication at the index examination in 2009 were included. Subjects were categorized into 8 groups according to the 2017 American College of Cardiology/American Heart Association blood pressure (BP) guidelines: normal BP, elevated BP, stage 1 IDH, stage 1 ISH, stage 1 SDH, stage 2 IDH, stage 2 ISH, and stage 2 SDH. The primary outcome was new-onset AF. During a median follow-up of 8.3 years, 7347 subjects had incident AF (0.3 per 1000 person-years). Compared with normal BP, stage 1 IDH (adjusted hazard ratio, 1.160 [95% CI, 1.086–1.240]) and stage 1 SDH (1.250 [1.165–1.341]) were associated with higher risks of incident AF, but not stage 1 ISH. Stage 2 IDH, ISH, and SDH were associated with higher risks of incident AF by 24%, 37%, and 61%, respectively. Stage 1 IDH and SDH were associated with higher risks of incident AF compared with normal BP. The risk of incident AF with stage 2 IDH was similar to that of stage 1 SDH. Optimal BP control, including diastolic BP, is associated with the lowest risk of new-onset AF, even among young adults.

The different risk factors for isolated diastolic hypertension and isolated systolic hypertension: a national survey

Background Hypertension is highly prevalent and is one of the modifiable risk factors for cardiovascular outcomes. Isolated diastolic hypertension (IDH), however, tends to be ignored due to insufficient recognition. We sought to depict the clinical manifestation of IDH and isolated systolic hypertension (ISH) to find a more efficient way to improve the management. Methods Patients with primary hypertension aged over 18 years were investigated from all over the country using convenience sampling during 2017–2019. IDH was defined as systolic blood pressure (SBP) < 140 mmHg and diastolic blood pressure (DBP) ≥90 mmHg. ISH was defined as SBP ≥ 140 mmHg and DBP < 90 mmHg. Results A total of 8548 patients were screened, and 8475 participants were included. The average age was 63.67 ± 12.78 years, and males accounted for 54.4%. Among them, 361 (4.3%) had IDH, and 2096 had ISH (24.7%). Patients with IDH (54.84 ± 13.21 years) were much younger. Aging turned out to be negatively associated with IDH but positively associated with ISH. Multivariate logistic regression analysis showed BMI was a significant risk factor for IDH (OR 1.30, 95%CI 1.05–1.61, p = 0.018), but not for ISH (OR 1.05, 95%CI 0.95–1.16, p = 0.358). Moreover, smoking was significantly associated with IDH (OR 1.36, 95%CI 1.04–1.78, p = 0.026) but not with ISH (OR 1.04, 95%CI 0.90–1.21, p = 0.653). Conclusions Patients with IDH were much younger, and the prevalence decreased with aging. BMI and smoking were remarkably associated with IDH rather than ISH. Keeping fit and giving up smoking might be particularly efficient in the management of young patients with IDH. Trial registration NCT03862183, retrospectively registered on March 5, 2019.

Clinical profile of isolated systolic hypertension in elderly

Isolated systolic hypertension is the most common hemodynamic form of hypertension in the elderly. With a rapidly aging population, the prevalence of hypertension, particularly isolated systolic hypertension, is increasing steadily. Isolated systolic hypertension is associated with substantial mortality and morbidity, particularly of cerebrovascular disease. It is a rapidly growing public health concern and its management continues to remain a challenge to practicing physicians. Recent studies like the Systolic Blood Pressure Intervention Trial (SPRINT) and Heart Outcomes Prevention Evaluation (HOPE)-3 have implications for antihypertensive therapy in general and for the management of isolated systolic hypertension in particular.
