Reasons for Uncontrolled Blood Pressure Among US Adults: Data From the US National Health and Nutrition Examination Survey

Stroke Care in South Asia - Identifying Gaps for Future Action

Stroke causes around 730,000 deaths in South Asia, nearly half of stroke-related deaths in developing countries. This highlights the need to address health system responses, considering poverty, service quality, and availability. The article identifies four key challenges in stroke management and rehabilitation in South Asia, emphasizing long-term monitoring, risk factor control, and community surveillance, drawing on experiences from Nepal.

Food insecurity and the risk of mortality among Hispanics with hypertension

BACKGROUND AND AIMS

Hypertension continues to be a major public health problem affecting almost half of the adults in the US. The intersection of hypertension with food insecurity has not been well-examined specifically among minority populations. We aimed to examine the influence of food insecurity on mortality among adult Hispanics.

METHODS AND RESULTS

Data on adult Hispanic (age≥ 20 years) respondents of the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2010 were analyzed. Mortality was assessed by linking these data with the National Death Index through December 31, 2019. Using complex samples Cox regression analysis, the relationship between hypertension, food insecurity, and mortality was assessed. Sociodemographic (age, gender, poverty-income-ratio, marital status, and citizenship status) and health-related characteristics (COPD, diabetes, cardiovascular disease, chronic kidney disease) of the population were included as covariates in the regression analysis to assess mortality risk. The crude hazard ratio (HR) for overall mortality related to hypertension was 4.95 (95% confidence interval [CI] = 4.22-5.82, p < .001). The adjusted HR was elevated, 2.01 (95%CI = 1.50-2.70, p < .001), among individuals with both hypertension and food insecurity. However, among individuals with hypertension and no food insecurity, there was no statistically significant increase in the risk of mortality (HR = 1.09, 95%CI = 0.89-1.34, p > 0.05).

CONCLUSIONS

In adult Hispanics, food insecurity significantly increases the risk of mortality among those with hypertension compared to food-secure individuals. Clinicians should be sensitized to the need for food security among Hispanics with hypertension to effectively manage hypertension and reduce premature mortality.

Prevalence of and factors associated with uncontrolled hypertension among patients with early chronic kidney disease attending tertiary hospitals in Dodoma, Tanzania: a cross-sectional study

OBJECTIVE

To determine the prevalence of uncontrolled hypertension and its associated factors among patients with early chronic kidney disease (CKD) attending medical outpatient clinics at tertiary hospitals in Dodoma, Tanzania.

DESIGN

Cross-sectional study.

SETTING

Two tertiary hospitals in Dodoma, Tanzania.

PARTICIPANTS

The participants in this study were adult patients (≥18 years) with early CKD stages (1, 2 and 3) who were attending nephrology and medical outpatient clinics from November 2020 to March 2021. Patients who had been attending the clinic for at least 3 months, had baseline clinical data on their files, had estimated glomerular filtration rate (eGFR) ≥30 mL/min/1.73 m2 and who provided written informed consent were eligible. A total of 352 patients were enrolled, of whom 182 were men and 170 were women.

OUTCOME MEASURE

The dependent variable was uncontrolled hypertension among patients with early CKD, based on blood pressure measurements.

RESULTS

The prevalence of hypertension was 58.5% (206 of 352) and the prevalence of uncontrolled hypertension was 58.3% (120 of 206). Among patients with uncontrolled hypertension, 88.3% (106 of 120) had CKD stage 3, 80.2% (96 of 120) reported non-adherence to antihypertensives, 76.7% (92 of 120) were overweight or obese, 72.5% (87 of 120) reported current alcohol use and 26.7% (32 of 120) had diabetes mellitus. Factors that contributed to higher odds of uncontrolled hypertension were: age ≥50 years (OR=5.17, 95 % CI 2.37 to 13.33, p=0.001), alcohol use (OR=11.21, 95% CI 3.83 to 32.84, p=0.001), non-adherence to antihypertensives (OR=10.19, 95% CI 4.22 to 24.61, p=0.001), overweight/obesity (OR=6.28, 95% CI 2.54 to 15.53, p=0.001) and CKD stage 3 (OR=3.52, 95% CI 1.32 to 9.42, p=0.012).

CONCLUSION

Uncontrolled hypertension was highly prevalent among patients with early CKD in this setting and was associated with age, current alcohol use, non-adherence to antihypertensives, overweight/obesity and declining eGFR.

A pragmatic clinical trial assessing the effect of a targeted notification and clinical support pathway on the diagnostic evaluation and treatment of individuals with left ventricular hypertrophy (NOTIFY-LVH)

BACKGROUND

Electronic health records contain vast amounts of cardiovascular data, including potential clues suggesting unrecognized conditions. One important example is the identification of left ventricular hypertrophy (LVH) on echocardiography. If the underlying causes are untreated, individuals are at increased risk of developing clinically significant pathology. As the most common cause of LVH, hypertension accounts for more cardiovascular deaths than any other modifiable risk factor. Contemporary healthcare systems have suboptimal mechanisms for detecting and effectively implementing hypertension treatment before downstream consequences develop. Thus, there is an urgent need to validate alternative intervention strategies for individuals with preexisting-but potentially unrecognized-LVH.

METHODS

Through a randomized pragmatic trial within a large integrated healthcare system, we will study the impact of a centralized clinical support pathway on the diagnosis and treatment of hypertension and other LVH-associated diseases in individuals with echocardiographic evidence of concentric LVH. Approximately 600 individuals who are not treated for hypertension and who do not have a known cardiomyopathy will be randomized. The intervention will be directed by population health coordinators who will notify longitudinal clinicians and offer to assist with the diagnostic evaluation of LVH. Our hypothesis is that an intervention that alerts clinicians to the presence of LVH will increase the detection and treatment of hypertension and the diagnosis of alternative causes of thickened myocardium. The primary outcome is the initiation of an antihypertensive medication. Secondary outcomes include new hypertension diagnoses and new cardiomyopathy diagnoses. The trial began in March 2023 and outcomes will be assessed 12 months from the start of follow-up.

CONCLUSION

The NOTIFY-LVH trial will assess the efficacy of a centralized intervention to improve the detection and treatment of hypertension and LVH-associated diseases. Additionally, it will serve as a proof-of-concept for how to effectively utilize previously collected electronic health data to improve the recognition and management of a broad range of chronic cardiovascular conditions.

Hypertension, uncontrolled hypertension and resistant hypertension: prevalence, comorbidities and prescribed medications in 228,406 adults resident in urban areas. A population-based observational study

Although hypertension is the leading cause of cardiovascular disease and premature death worldwide, it remains difficult to control. The prevalence of uncontrolled and resistant hypertension (RH) may be underestimated and can reach up to 50% of all hypertensive patients. The aim of this observational study was to analyze the prevalence of hypertension, uncontrolled hypertension and RH, and their associations with risk factors or diseases in a large cohort of patients referred to primary care physician. In a population of 228406 adults, we only collected data from people with a diagnosis of arterial hypertension for a total of 43,526 patients. For this purpose, we used the MySQL database, run by Azalea.NET, built on the medical records of 150 General Practitioners (GPs). Patient data included sex, age, blood pressure (BP) values, number of antihypertensive drugs and presence of major cardiovascular comorbidities. We classified patients with RH as those treated with 3 different antihypertensive agents, with recorded BP ≥ 140/90 mmHg, or patients taking ≥ 4 medications. The prevalence of hypertension was 19.06%, that of resistant hypertension was 2.46% of the whole population and 20.85% of the hypertensive group. Thirteen thousand hundred, forty-six patients (30.20% of the hypertensive group) had uncontrolled BP (≥ 140/90 mmHg), whereas 16,577 patients did not have BP measurements done in the last 2 years (38.09% of the hypertensive group). Patients with uncontrolled BP were mainly female, used less drugs and showed a lower prevalence of all major cardiovascular comorbidities, except for diabetes. Instead, patients with RH had a significantly higher prevalence of all considered comorbidities compared to those without RH. Our results evidence that a broad number of patients with hypertension, especially those without comorbidities or with a low number of antihypertensive drugs, do not achieve adequate BP control. To improve the clinical management of these patients it is very important to increase the collaboration between GPs and clinical specialists of hypertension.

Evidence for Age Bias Contributing to Therapeutic Inertia in Blood Pressure Management: A Secondary Analysis of SPRINT

BACKGROUND

Despite evidence supporting the cardiovascular and cognitive benefits of intensive blood pressure management, older adults have the lowest rates of blood pressure control. We determined the association between age and therapeutic inertia (TI) in SPRINT (Systolic Blood Pressure Intervention Trial), and whether frailty, cognitive function, or gait speed moderate or mediate these associations.

METHODS

We performed a secondary analysis of SPRINT of participant visits with blood pressure above randomized treatment goal. We categorized baseline age as <60, 60 to <70, 70 to <80, and ≥80 years and TI as no antihypertensive medication intensification per participant visit. Generalized estimating equations generated odds ratios for TI associated with age, stratified by treatment group based on nested models adjusted for baseline frailty index score (fit [frailty index, ≤0.10], less fit [0.10

RESULTS

Participants 60 to <70, 70 to <80, and ≥80 years of age had a higher prevalence of TI in both treatment groups versus participants <60 years of age (standard: 59.7%, 60.5%, and 60.1% versus 56.0%; 29 527 participant visits; intensive: 55.1%, 57.2%, and 57.8% versus 53.8%; 47 129 participant visits). The adjusted odds ratios for TI comparing participants ≥80 versus <60 years of age were 1.32 (95% CI, 1.14-1.53) and 1.25 (95% CI, 1.11-1.41) in the standard and intensive treatment groups, respectively. Adjustment for frailty, cognitive function, or gait speed did not attenuate the association or demonstrate effect modification (all Pinteraction, >0.10).

CONCLUSIONS

Older age is associated with greater TI independent of physical or cognitive function, implying age bias in hypertension management.
