Global Risk Assessment to Guide Blood Pressure Management in Cardiovascular Disease Prevention

Comparison of Patients Classified as High-Risk between International Cardiovascular Disease Primary Prevention Guidelines

Background: Cardiovascular disease (CVD) primary prevention guidelines classify people at high risk and recommended for pharmacological treatment based on clinical criteria and absolute CVD risk estimation. Despite relying on similar evidence, recommendations vary between international guidelines, which may impact who is recommended to receive treatment for CVD prevention. Objective: To determine the agreement in treatment recommendations according to guidelines from Australia, England and the United States. Methods: Cross-sectional analysis of the National Health and Nutrition Examination Survey (n = 2647). Adults ≥ 40 years were classified as high-risk and recommended for treatment according to Australia, England and United States CVD prevention guidelines. Agreement in high-risk classification and recommendation for treatment was assessed by Kappa statistic. Results: Participants were middle aged, 49% were male and 38% were white. The proportion recommended for treatment was highest using the United States guidelines (n = 1318, 49.8%) followed by the English guidelines (n = 1276, 48.2%). In comparison, only 26.6% (n = 705) of participants were classified as recommended for treatment according to the Australian guidelines. There was moderate agreement in the recommendation for treatment between the English and United States guidelines (κ = 0.69 [0.64-0.74]). In comparison, agreement in recommendation for treatment was minimal between the Australian and United States guidelines (κ = 0.47 [0.43-0.52]) and weak between the Australian and English guidelines (κ = 0.50 [0.45-0.55]). Conclusions: Despite similar evidence underpinning guidelines, there is little agreement between guidelines regarding the people recommended to receive treatment for CVD prevention. These findings suggest greater consistency in high-risk classification between CVD prevention guidelines may be required.

Individualized prevention of proton pump inhibitor related adverse events by risk stratification

Proton pump inhibitors (PPIs) are commonly used for gastric acid-related disorders, but their safety profile and risk stratification for high-burden diseases need further investigation. Analyzing over 2 million participants from five prospective cohorts from the US, the UK, and China, we found that PPI use correlated with increased risk of 15 leading global diseases, such as ischemic heart disease, diabetes, respiratory infections, and chronic kidney disease. These associations showed dose-response relationships and consistency across different PPI types. PPI-related absolute risks increased with baseline risks, with approximately 82% of cases occurring in those at the upper 40% of the baseline predicted risk, and only 11.5% of cases occurring in individuals at the lower 50% of the baseline risk. While statistical association does not necessarily imply causation, its potential safety concerns suggest that personalized use of PPIs through risk stratification might guide appropriate decision-making for patients, clinicians, and the public.

Effect of ketogenic diet on blood pressure: A GRADE-Assessed systematic review and meta-analysis of randomized controlled trials

AIMS

Cardiovascular diseases (CVDs) are major causes of mortality around the world. High blood pressure (BP) or hypertension is one of the most significant predisposing factors to CVDs. Ketogenic diets (KDs) have been the center of attention for their possible health benefits. The aim of this analysis is to study the impact of KDs on BP through the existing literature.

DATA SYNTHESIS

We investigated the impact of KDs on systolic and diastolic blood pressures (SBP and DBP) conducted in the format of randomized controlled trials (RCTs). Four online databases (PubMed/Medline, SCOPUS, Cochrane Library, and Google Scholar) were searched from inception up to November 2022. Subgroup analyses were carried out to find the sources of heterogeneities. Twenty-three RCTs with 1664 participants were identified. KDs did not exert any significant impacts on SBP (WMD: -0.87 mmHg, 95% CI: -2.05, 0.31) nor DBP (WMD: -0.11 mmHg, 95% CI -1.14, 0.93). Subgroup analyses did not reveal any further information. Also, non-linear dose-response analysis could not detect any associations between the percentage of calorie intake from fat in the KD format and BP levels.

CONCLUSION

KDs do not seem to be effective in improving BP. Nonetheless, further investigations are recommended to examine the proportion of fat intake needed to induce favorable clinical impacts.

Association Between Alcohol Consumption and Blood Pressure Levels Among HIV Sero-Positive and Sero-Negative Cohorts: A Secondary Analysis of the Vukuzazzi Study

BACKGROUND

The effect of hypertension is aggravated by lifestyle factors such as alcohol consumption. This study sought to determine the association between alcohol consumption and the level of blood pressures among HIV seronegative and seropositive cohorts.

METHODS

This secondary analysis was performed on a cross-sectional survey data of 17 922 participants during the period between 2018 and 2020. A questionnaire was used to obtain participants' alcohol consumption history, which was categorized into non-alcohol consumers, non-heavy alcohol consumers, and heavy alcohol consumers. A linear regression model was used to establish relationships among participants with raised blood pressure (BP ≥ 140/90 mmHg).

RESULTS

Out of the total participants, 3553 (19.82%) were hypertensives. Almost 13% of the hypertensives (n = 458; 12.89%) were undiagnosed, and 12.44 % (442) had uncontrolled hypertension. About 14.52% of the hypertensives (3553) were not on any antihypertensive medication. Male non-consumers of alcohol had the highest systolic and diastolic BP; uncontrolled systolic BP (165.53 ± 20.87 mmHg), uncontrolled diastolic BP (102.28 ± 19.21mmHg). Adjusted for covariates, moderate alcohol consumption was associated with HTN among participants who were HIV seropositive [unadjusted (RR = 1.772, P = .006, 95% CI (1.178-2.665)], [RR = 1.772, P = .005, 95% CI (1.187-2.64)]. [unadjusted RR = 1.876, P = .036, 95% CI (1.043-3.378)], adjusted RR = 1.876, P = .041, 95% CI (1.024-3.437). Both moderate and heavy alcohol consumption were significantly related to hypertension among HIV sero-negative [unadjusted model, moderate consumption RR = 1.534 P = .003, 95% CI (1.152-2.044)], [adjusted model, moderate alcohol consumption RR = 1.535, P = .006, 95% CI (1.132-2.080)], [unadjusted model, heavy alcohol consumption, RR = 2.480, P = .030, 95% CI (1.091-5.638)], [adjusted model RR = 2.480, P = .034, 95% CI (1.072-5.738)].

CONCLUSION

Alcohol consumption is significantly related to increase BP regardless of HIV infection.

Association Between Use of Sodium-Glucose Cotransporter-2 Inhibitors or Angiotensin Receptor-Neprilysin Inhibitor and the Risk of Atherosclerotic Cardiovascular Disease With Coexisting Diabetes and Heart Failure

PURPOSE

This study was to investigate the association between the use of Sodium-glucose Cotransporter-2 inhibitors (SGLT2i) or angiotensin receptor-neprilysin inhibitor (ARNI; ie, Sacubitril + valsartan, Product name ENTRESTO) and the risk of atherosclerotic cardiovascular disease (ASCVD) in patients with coexisting diabetes and heart failure. Specifically, the study compared outcomes between patients using SGLT2i or valsartan + sacubitril and those not using these medications.

METHODS

This study utilized data from the National Health Insurance Research Database (NHIRD) from 2017 to 2018. The case group consisted of 8691 patients with coexisting diabetes and heart failure who did not use SGLT2i or Entresto, while the control group consisted of 8691 patients with coexisting diabetes and heart failure who used SGLT2i or Entresto. The primary outcome was ASCVD, including a composite of cardiovascular death and hospitalization for worsening heart failure. Secondary outcomes included all-cause death, cause of cardiovascular death, and recurrence of heart failure, non-fatal myocardial infarction, non-fatal stroke (including ischemic stroke and hemorrhagic stroke) and new renal replacement therapy.

RESULTS

The study found that the use of SGLT2 inhibitors or ARNI was associated with a lower risk of ASCVD in patients with coexisting diabetes and heart failure.

CONCLUSION

The study suggests that the use of SGLT2 inhibitors, alone or in combination with Entresto, may be effective in reducing the risk of ASCVD and its associated adverse outcomes in patients with diabetes and heart failure. This finding has important implications for the management of these conditions.

Estimated Population Health Benefits of Intensive Systolic Blood Pressure Treatment Among SPRINT-Eligible US Adults

BACKGROUND

The Systolic Blood Pressure Intervention Trial (SPRINT) demonstrated an intensive (<120 mm Hg) vs. standard (<140 mm Hg) systolic blood pressure (SBP) goal lowered cardiovascular disease (CVD) risk. Estimating the effect of intensive SBP lowering among SPRINT-eligible adults most likely to benefit can guide implementation efforts.

METHODS

We studied SPRINT participants and SPRINT-eligible participants in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study and National Health and Nutrition Examination Surveys (NHANES). A published algorithm of predicted CVD benefit with intensive SBP treatment was used to categorize participants into low, medium, or high predicted benefit. CVD event rates were estimated with intensive and standard treatment.

RESULTS

Median age was 67.0, 72.0, and 64.0 years in SPRINT, SPRINT-eligible REGARDS, and SPRINT-eligible NHANES participants, respectively. The proportion with high predicted benefit was 33.0% in SPRINT, 39.0% in SPRINT-eligible REGARDS, and 23.5% in SPRINT-eligible NHANES. The estimated difference in CVD event rate (standard minus intensive) was 7.0 (95% confidence interval [CI] 3.4-10.7), 8.4 (95% CI 8.2-8.5), and 6.1 (95% CI 5.9-6.3) per 1,000 person-years in SPRINT, SPRINT-eligible REGARDS participants, and SPRINT-eligible NHANES participants, respectively (median 3.2-year follow-up). Intensive SBP treatment could prevent 84,300 (95% CI 80,800-87,920) CVD events per year in 14.1 million SPRINT-eligible US adults; 29,400 and 28,600 would be in 7.0 million individuals with medium or high predicted benefit, respectively.

CONCLUSIONS

Most of the population health benefit from intensive SBP goals could be achieved by treating those characterized by a previously published algorithm as having medium or high predicted benefit.

Effect of Sequential Nephron Blockade versus Dual Renin-Angiotensin System Blockade Plus Bisoprolol in the Treatment of Resistant Hypertension, a Randomized Controlled Trial (Resistant Hypertension on Treatment - ResHypOT)

Introduction

Hypertension is the most important modifiable risk factor for cardiovascular disease and a leading public health concern.

Objectives

The primary aim was to compare sequential nephron blockade (SNB) versus dual renin-angiotensin system blockade (DRASB) plus bisoprolol in patients with resistant hypertension to observe reductions in systolic and diastolic blood pressure (SBP and DBP) levels after 20 weeks of treatment.

Material and Methods

This trial was an open-label, prospective, randomized, parallel-group, clinical study with optional drug up-titration. Participants were evaluated during five visits at 28-day intervals.

Results

The mean age was 55.5 years in the SNB and 58.4 years in the DRASB + bisoprolol group (p=NS). Significant office BP reductions were observed in both groups. SNB group, SBP decreased from 174.5±21.0 to 127.0±14.74 mmHg (p<0.0001), and DBP decreased from 105.3±15.5 to 78.11±9.28 mmHg (p<0.0001). DRASB group, SBP decreased from 178.4±21.08 to 134.4 ± 23.25 mmHg (p<0.0001) and DBP decreased from 102.7±11.07 to 77.33±13.75 mmHg (p<0.0001). Ambulatory blood pressure monitoring (ABPM) showed also significant SBP and DBP reductions in both groups (p<0.0001).

Conclusion

In patients with RHTN adherent to treatment, SNB and DRASB plus bisoprolol showed excellent therapeutic efficacy, although SNB was associated with earlier SBP reduction.

Machine learning outperforms traditional logistic regression and offers new possibilities for cardiovascular risk prediction: A study involving 143,043 Chinese patients with hypertension

Introduction

Identifying people at risk of cardiovascular diseases (CVD) is a cornerstone of preventive cardiology. We developed machine learning (ML) algorithms and investigated their performance in predicting patients' current CVD risk (coronary heart disease and stroke in this study).

Materials and methods

We compared traditional logistic regression (LR) with five ML algorithms LR with Elastic-Net, Random Forest (RF), XGBoost (XGB), Support Vector Machine, Deep Learning, and an Ensemble model averaging predictions from RF, XGB, and Deep Learning for CVD risk prediction using pre-existing patient-level data from a multi-center, cross-sectional study (the Microalbuminuria Screening in Hypertensive Patients Project initiated by the China International Exchange and Promotive Association for Medical and Healthcare) that enrolled 143,043 patients with hypertension from 600 tertiary, secondary, or community hospitals. Each of the five ML algorithms incorporated 18 variables, such as demographics, examinations, comorbidities, and treatment regimens, and were trained and evaluated using 5-fold cross-validation. Predictive accuracy was assessed by the area under the receiver operating curve (AUROC).

Results

Patients' mean age was 62 ± 12 years and 57% were men. Advanced ML algorithms outperformed the traditional LR model. Particularly, the Ensemble model had superior discrimination with an AUROC of 0.760 than LR (AUC = 0.737) and other tested models.

Conclusion

We establishes an Ensemble model that shows better performance in predicting patients' current CVD risk using routine information compared to the traditional LR model. ML can help physicians design follow-up plans with more accurate results, offering new possibilities for short-term risk prediction and early detection. Further, ML models can be trained with longitudinal data and used to predict long-term CVD risks, thereby informing CVD prevention.

Predicted cardiovascular disease risk and prescribing of antihypertensive therapy among patients with hypertension in Australia using MedicineInsight

Hypertension guidelines recommend that absolute cardiovascular disease (CVD) risk guide the management of hypertensive patients. This study aimed to assess the proportion of patients with diagnosed hypertension with sufficient data to calculate absolute CVD risk and determine whether CVD risk is associated with prescribing of antihypertensive therapies. This was a cross-sectional study using a large national database of electronic medical records of patients attending general practice in 2018 (MedicineInsight). Of 571,492 patients aged 45-74 years without a history of CVD, 251,733 [40.6% (95% CI: 39.8-41.2)] had a recorded hypertension diagnosis. The proportion of patients with sufficient recorded data available to calculate CVD risk was higher for patients diagnosed with hypertension [51.0% (95% CI: 48.0-53.9)] than for patients without a diagnosis of hypertension [38.7% (95% CI: 36.5-41.0)]. Of those patients with sufficient data to calculate CVD risk, 29.3% (95% CI: 28.1-30.6) were at high risk clinically, 6.0% (95% CI: 5.8-6.3) were at high risk based on their CVD risk score, 12.8% (95% CI: 12.5-13.2) at moderate risk and 51.8% (95% CI: 50.8-52.9) at low risk. The overall prevalence of antihypertensive therapy was 60.9% (95% CI: 59.3-62.5). Prescribing was slightly lower in patients at high risk based on their CVD risk score [57.4% (95% CI: 55.4-59.4)] compared with those at low [63.3% (95% CI: 61.9-64.8)] or moderate risk [61.8% (95% CI: 60.2-63.4)] or at high risk clinically [64.1% (95% CI: 61.9-66.3)]. Guideline adherence is suboptimal, and many patients miss out on treatments that may prevent future CVD events.

Nebivolol and incident cardiovascular events in hypertensive patients compared with nonvasodilatory beta blockers

OBJECTIVE

Nonvasodilatory beta blockers are associated with inferior cardiovascular event reduction compared with other antihypertensive classes, and there is uncertainty about first-line use of beta blockers for hypertension in guidelines. The third generation vasodilatory beta blocker nebivolol has unique beneficial effects on central and peripheral vasculature. Our objective was to compare longitudinal cardiovascular outcomes of hypertensive patients taking nebivolol with those taking the nonvasodilatory beta blockers metoprolol and atenolol.

METHODS

We performed a retrospective cohort analysis of hypertensive adults in the University of Colorado health system, without preceding diagnosis of cardiovascular or cerebrovascular disease. The primary outcome was composite incident heart failure, stroke, myocardial infarction, angina, or coronary revascularization. Mahalanobis 1:2 distance matching and Cox proportional hazards regression was used. Matching and regression variables included baseline demographics, socioeconomic factors, medical insurance type, prescribing provider type, cardiovascular risk factors, Charlson comorbidity index, other medications, and follow-up duration.

RESULTS

After matching, patients were predominantly women (54%, 3085 of 5705) and non-Hispanic Caucasian (79%, 4534 of 5705), with median age of 58. In matched Cox regression analysis, nebivolol was associated with 17% reduction in incident cardiovascular events compared with all nonvasodilatory beta blockers [hazard ratio 0.83, 95% confidence interval (CI) 0.74-0.94, P  = 0.004], and 24% reduction compared with metoprolol (hazard ratio 0.76, CI 0.66-0.87, P = 0.0001).

CONCLUSION

The vasodilatory beta blocker nebivolol was associated with reduced incident cardiovascular events compared with nonvasodilatory beta blockers. Additional study of other beta blockers is necessary to determine if this is a vasodilatory beta blocker class effect or is specific to nebivolol.

Prior Cardiovascular Treatments-A Key Characteristic in Determining Medication Adherence After an Acute Myocardial Infarction

Objective: To investigate long-term adherence to guideline-recommended cardioprotective medications following hospitalization for an acute myocardial infarction (AMI), and identify characteristics associated with adherence.

Methods: An Australian population-based cohort study was used to identify participants who had their first AMI between 2006 and 2014 and were alive after 12 months. Linked routinely collected hospital, and prescription medication claims data was used to study adherence over time. Predictors and rates of adherence to both lipid-lowering medication and renin-angiotensin system blockade at 12 months post-AMI was assessed.

Results: 14,200 people (mean age 69.9 years, 38.7% female) were included in our analysis. At 12 months post-AMI, 29.5% (95% CI: 28.8–30.3%) of people were adherent to both classes of medication. Individuals receiving treatment with both lipid-lowering medication and renin-angiotensin system blockade during the 6 months prior to their AMI were over 9 times more likely to be adherent to both medications at 12 months post-AMI (66.2% 95% CI: 64.8–67.5%) compared to those with no prior medication use (treatment naïve) (7.1%, 95% CI: 6.4–7.9%). Prior cardiovascular treatment was the strongest predictor of long-term adherence even after adjusting for age, sex, education and income.

Conclusions: Despite efforts to improve long-term medication adherence in patients who have experienced an acute coronary event, considerable gaps remain. Of particular concern are people who are commencing guideline-recommended cardioprotective medication at the time of their AMI. The relationship between prior cardiovascular treatments and post AMI adherence offers insight into the support needs for the patient. Health care intervention strategies, strengthened by enabling policies, are needed to provide support to patients through the initial months following their AMI.

Regular use of proton-pump inhibitors and risk of stroke: a population-based cohort study and meta-analysis of randomized-controlled trials

BACKGROUND

Although randomized controlled trials (RCTs) have suggested a non-significant increased risk of stroke among proton pump inhibitor (PPI) users, the association has not been confirmed. We evaluated the association between regular use of PPIs and incident stroke and identified population groups at high net risk.

METHODS

This is a prospective analysis of 492,479 participants free of stroke from the UK biobank. Incident stroke was identified through linkage to hospital admission and death registries using the International Classification of Diseases (ICD)-10 codes (I60, I61, I63, and I64). We evaluated hazard ratios (HRs) adjusting for demographic factors, lifestyle habits, prevalent comorbidities, concomitant use of medications, and indications of PPIs. We assessed the risk differences (RDs) according to the baseline Framingham Stroke Risk Score. In the meta-analysis, we searched PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials (from 1988 to 1 June 2020) for randomized trials comparing PPIs with other interventions, placebo, or no treatment on stroke risk. Results were combined using a fix-effect meta-analysis (Mantel-Haenszel method).

RESULTS

We documented 5182 incident strokes over 3,935,030 person-years of follow-up. Regular PPI users had a 16% higher risk of stroke than non-users (HR 1.16, 95% CI 1.06 to 1.27). The estimated effect was similar to our meta-analysis of nine RCTs (case/participants 371/26,642; RR 1.22, 95% CI 1.00 to 1.50; quality of evidence: moderate). The absolute effect of PPI use on stroke increased with the baseline Framingham Stroke Risk Score, with an RD of 1.34‰, 3.32‰, 4.83‰, and 6.28‰ over 5 years for the lowest, quartile 2, quartile 3, and the highest quartile, respectively.

CONCLUSIONS

Regular use of PPIs was associated with an increased risk of stroke, with a higher absolute risk observed in individuals with high baseline stroke risk. Physicians should therefore exercise caution when prescribing PPIs. An assessment of the underlying stoke risk is recommended for individualized use of PPIs.

General practitioners maintain a focus on blood pressure management rather than absolute cardiovascular disease risk management

BACKGROUND

Absolute cardiovascular disease (aCVD) risk assessment is recommended in CVD prevention guidelines. Yet, General Practitioners (GPs) often focus on single risk factors, including blood pressure (BP). Pathology services may be suitable to undertake high-quality automated unobserved BP (AOBP) measurement and aCVD risk assessment. This study explored GP attitudes towards AOBP measurement via pathology services and the role of BP in aCVD risk management.

METHODS

A brief survey was completed, after which a focus group (n = 8 GPs) and interviews (n = 10 GPs) explored attitudes to AOBP and aCVD risk via pathology services with an example pathology report discussed. Verbatim transcripts were thematically coded.

RESULTS

GPs predominantly used doctor-measured BP despite low levels of confidence. High BP measured by AOBP reported with aCVD risk via pathology services, would prompt a follow-up response. However, GPs focused on BP management. GPs were concerned about AOBP equivalency to routine BP measurements. After protocol explanation, GPs reported AOBP could value-add to care delivery.

CONCLUSION

GPs lacked familiarity of AOBP and maintained a focus on BP management in the context of absolute CVD risk. Targeted education on AOBP and BP management as part of absolute CVD risk is needed to support guideline-directed care in practice.

A Model for Risk Prediction of Cerebrovascular Disease Prevalence-Based on Community Residents Aged 40 and above in a City in China

Cerebrovascular disease (CVD) is the leading cause of death in many countries including China. Early diagnosis and risk assessment represent one of effective approaches to reduce the CVD-related mortality. The purpose of this study was to understand the prevalence and influencing factors of cerebrovascular disease among community residents in Qingyunpu District, Nanchang City, Jiangxi Province, and to construct a model of cerebrovascular disease risk index suitable for local community residents. A stratified cluster sampling method was used to sample 2147 community residents aged 40 and above, and the prevalence of cerebrovascular diseases and possible risk factors were investigated. It was found that the prevalence of cerebrovascular disease among local residents was 4.5%. Poisson regression analysis found that old age, lack of exercise, hypertension, diabetes, smoking, and family history of cerebrovascular disease are the main risk factors for local cerebrovascular disease. The relative risk ORs were 3.284, 2.306, 2.510, 3.194, 1.949, 2.315, respectively. For these six selected risk factors, a cerebrovascular disease risk prediction model was established using the Harvard Cancer Index method. The R value of the risk prediction model was 1.80 (sensitivity 81.8%, specificity 47.0%), which was able to well predict the risk of cerebrovascular disease among local residents. This provides a scientific basis for the further development of local cerebrovascular disease prevention and control work.

[Evidence-Based Information Which Could Influence Arterial Hypertension Treatment Approach after Publication of SPRINT Trial Results]

The article discusses results of secondary analysis of the data obtained in the SPRINT study and published in recent years. Unresolved issues in the tactics of managing patients with arterial hypertension are discussed. One of such issues is choosing an optimum level of blood pressure (BP) for a subgroup of patients with certain characteristics, including elderly and senile patients, patients with chronic kidney disease, and patients with arterial hypertension who continue smoking. The article discusses calculation of a threshold of risk for complications of cardiovascular diseases, at which a maximum advantage of intensified regimens of antihypertensive therapy could be achieved. In addition, the article addresses approaches to selection of antihypertensive drugs in the current conditions. The authors discussed the role of candesartan in the treatment of arterial hypertension, a sartan most studied in a broad range of patients. The issue of a rapid increase in BP without a damage to target organs is addressed; evidence for the role of captopril in such clinical situation is provided.

Effects of combined 17β-estradiol and progesterone on weight and blood pressure in postmenopausal women of the REPLENISH trial

Objective:

To examine the impact of a single-capsule 17β-estradiol (E2)/progesterone (P4) on weight and blood pressure (BP) when treating moderate to severe vasomotor symptoms in postmenopausal women with a uterus.

Methods:

Healthy postmenopausal women with a uterus (aged 40-65, body mass index ≤34 kg/m², BP ≤140/90 mm Hg) were randomized to daily E2/P4 (mg/mg; 1/100, 0.5/100, 0.5/50, 0.25/50) or placebo in the phase 3 REPLENISH trial (NCT01942668). Changes in weight and BP from baseline to month 12 were evaluated. Potentially clinically important changes were defined as increases or decreases from baseline in weight by ≥15% and ≥11.3 kg, systolic BP by ≥20 mm Hg (absolute value ≥160 or ≤90 mm Hg), and diastolic BP by ≥15 mm Hg (absolute value ≥90 or ≤60 mm Hg).

Results:

Overall mean changes in weight and BP from baseline to month 12 with E2/P4 were modest and generally not statistically or clinically significant versus placebo. Incidence of potentially clinically important changes was low for weight (E2/P4 vs placebo: 1.1-2.6% vs 2.2%), systolic BP (0.3-1.1% vs 1.1%), and diastolic BP (1.4-4.2% vs 3.2%). A small number of women had treatment-related, treatment-emergent adverse events of weight gain (1.4-2.6% vs 1.3%) or hypertension (0.2-1.2% vs 0%). Few women who discontinued E2/P4 had weight gain (1.6%) or hypertension (0.6%) as a primary reason. Efficacy profile on VMS was consistent with previous findings and not modified by body mass index.

Conclusions:

Twelve-month use of E2/P4 had no clinically meaningful impact on weight or BP in postmenopausal women of the REPLENISH study.

Wholegrain Consumption and Risk Factors for Cardiorenal Metabolic Diseases in Chile: A Cross-Sectional Analysis of 2016-2017 Health National Survey

Wholegrain (WG) consumption has been associated with reduced risk factors for cardiorenal metabolic diseases (CRMD). In Latin-America. WG intake is low and scarce studies on this subject have been found. We aimed to evaluate the association between WG consumption and risk factors for CRMD in the 2016-2017 Chilean-National Health Survey. This cross-sectional study included 3110 participants representative of a total population of 11,810,647 subjects > 18 y, not taking insulin and with complete data on CRMD risk factors. Outcomes were metabolic syndrome and its components, albuminuria, and impaired glomerular filtration rate (GFR). WG consumption was categorized as regular (≥every two days), sporadic (≥once a month), and non-consumers. Associations were analyzed by multivariable logistic regressions adjusted for confounders taking into account the complex sample design of the survey. Regular WG consumers showed a lower risk of high blood pressure (OR: 0.61, 95%CI: 0.41-0.91) compared to non-consumers in fully-adjusted models. Although inverse associations were noticed with other metabolic syndrome components and impaired GFR, none was statistically significant. The association between WG and BP remained robust in the sensitivity analysis. In conclusion regular WG consumption was associated with a 39% lower risk of high blood pressure in Chilean adults.

The Role of Lifestyle Factors in Controlling Blood Pressure among Hypertensive Patients in Two Health Facilities in Urban Ghana: A Cross-Sectional Study

Introduction

Despite efforts to combat hypertension by pharmacotherapy, hypertension control rates remain low. Lifestyle modifications of individuals diagnosed with hypertension have prospects for the prevention and control of hypertension. This study assessed the effect of modifiable lifestyle factors on blood pressure control among adults in urban Accra.

Methods

In this cross-sectional study, 360 diagnosed hypertensive patients who were ≥18 years old, selected from two secondary-level referral hospitals in the Greater Accra Region, were interviewed. Demographic information, diet components, and exercise assessments as well as blood pressure measurements were taken. Chi-squared tests and binomial logistic regression were used to determine the association between demographic and lifestyle factors with blood pressure control. Area under the receiver-operator curves (AUROC) was used to identify lifestyle factors predicting optimal blood pressure control among patients diagnosed with hypertension.

Results

Approximately 54.2% of participants had no knowledge of either causes or complications of hypertension. Similarly, 52.5% of patients that had not achieved blood pressure control lacked knowledge of causes or complications of hypertension. Longer time since diagnosis of 2–5 years (AOR = 0.08 (95% CI: 0.01–0.47)) and 6–10 years (AOR = 0.08 (95% CI: 0.01–0.50)) and diets, mainly composed of meat (AOR = 0.13 (95% CI: 0.02–0.70)) and starch (AOR = 0.14 (95% CI: 0.03–0.79)), predicted poor blood pressure control compared to patients diagnosed within a year and diets without meat and starch as main components, respectively. Additionally, engaging in some physical activity of 30 minutes to one hour (AOR = 5.64 (95% CI: 2.08–15.32)) and more than an hour (AOR = 11.38, 95% CI: 2.01–64.47)) predicted blood pressure control.

Conclusion

The study concludes that increased physical activity, abstaining from alcohol and smoking, increased intake of fruits and vegetables, and reduced intake of carbohydrates, meat, and fat have a positive influence on blood pressure control. Lifestyle modifying factors have a key role in complementing pharmacotherapy in hypertension control.

Managing Hypertension in the elderly: What's new?

Hypertension is the leading modifiable risk factor for cardiovascular events and mortality in the world. Hypertension is a major risk factor for cardiovascular events and mortality in the elderly. The 2017 American College of Cardiology/American Heart Association hypertension guidelines recommend treatment of noninstitutionalized ambulatory community-dwelling persons aged 65 years and older with an average systolic blood pressure of 130 ​mm Hg or higher or a diastolic blood pressure of 80 ​mm Hg or higher with lifestyle measures plus antihypertensive drug to lower the blood pressure to less than 130/80 ​mm Hg For elderly adults with hypertension and a high burden of comorbidities and limited life expectancy, clinical judgment, patient preference, and a team-based approach to assess risk/benefit is reasonable for decisions about the intensity of SBP lowering and the choice of antihypertensive drugs to use for treatment. Randomized clinical trials need to be performed in frail elderly patients with hypertension living in nursing homes. Elderly frail persons with prevalent and frequent falls, marked cognitive impairment, and multiple comorbidities requiring multiple antihypertensive drugs also need to be included in randomized clinical trials. Data on patients older than 85 years treated for hypertension are also sparse. These patients need clinical trial data. Finally, the effect of different antihypertensive drugs on clinical outcomes including serious adverse events needs to be investigated in elderly frail patients with hypertension and different comorbidities.

Managing the elderly patient with hypertension: current strategies, challenges, and considerations

Introduction: Hypertension is the leading modifiable risk factor for cardiovascular events and mortality in the world.Areas covered: An extensive literature review of articles and clinical trials on PUBMED on the topic of hypertension in the elderly from 1976 through January 2020 was conducted. This review article discusses clinical trials on treatment of hypertension in the elderly, the 2017 American College of Cardiology (ACC)/American Heart Association (AHA) hypertension guidelines, the 2018 European Society of Cardiology/European Society of Hypertension guidelines, and the treatment of hypertension and of resistant hypertension in the elderly.Expert opinion: The 2017 ACC/AHA hypertension guidelines recommend treatment of noninstitutionalized ambulatory community-dwelling adults aged 65 years and older with an average systolic blood pressure of 130 mm Hg or higher with lifestyle measures plus antihypertensive drug to lower the blood pressure to less than 130/80 mm Hg. For elderly adults with hypertension and a high burden of comorbidities and limited life expectancy, clinical judgment, patient preference, and a team-based approach to assess risk/benefit is reasonable for decisions about the intensity of SBP lowering and the choice of antihypertensive drugs to use for treatment.

Implications of the New 2017 American College of Cardiology/American Heart Association Guidelines for Hypertension

Automated validated devices should be used for measuring blood pressure (BP). The 2017 American College of Cardiology (ACC)/American Heart Association (AHA) hypertension guidelines recommend that a systolic BP between 120-129 mmHg with a diastolic BP less than 80 mmHg should be treated with lifestyle measures. These guidelines recommend treatment with lifestyle measures plus BP lowering drugs for secondary prevention of cardiovascular events in persons with clinical cardiovascular disease and an average systolic BP of ≥130 mmHg or an average diastolic BP≥80 mmHg. These guidelines recommend treatment with lifestyle measures plus BP lowering drugs for primary prevention of cardiovascular disease in persons with an estimated 10-year risk of atherosclerotic cardiovascular disease ≥ 10% and an average systolic BP ≥130 mmHg or an average diastolic BP ≥80 mmHg. These guidelines recommend treatment with lifestyle measures plus BP lowering drugs for primary prevention of cardiovascular disease in persons with an estimated 10-year risk of atherosclerotic cardiovascular disease of < 10% and an average systolic BP ≥140 mmHg or an average diastolic BP ≥ 90 mmHg. These guidelines recommend initiating antihypertensive drug therapy with 2 first-line drugs from different classes either as separate agents or in a fixed-dose combination in persons with a BP ≥140/90 mmHg or with a BP > 20/10 mmHg above their BP target. White coat hypertension must be excluded before starting treatment with antihypertensive drugs in persons with hypertension at low risk for atherosclerotic cardiovascular disease. Antihypertensive drug treatment for different disorders is discussed.

Resistant Hypertension On Treatment (ResHypOT): sequential nephron blockade compared to dual blockade of the renin-angiotensin-aldosterone system plus bisoprolol in the treatment of resistant arterial hypertension - study protocol for a randomized controlled trial

Background

Resistant hypertension is characterized when the blood pressure (BP) remains above the recommended goal after taking three antihypertensive drugs with synergistic actions at their maximum recommended tolerated doses, preferably including a diuretic. Identifying the contribution of intravascular volume and serum renin in maintaining BP levels could help tailor more effective hypertension treatment, whether acting on the control of intravascular volume or sodium balance, or acting on the effects of the renin-angiotensin-aldosterone system (RAAS) on the kidney.

Methods/design

This is a randomized, open-label, clinical trial is designed to compare sequential nephron blockade and its contribution to the intravascular volume component with dual blockade of the RAAS plus bisoprolol and the importance of serum renin in maintaining BP levels. The trial has two arms: sequential nephron blockade versus dual blockade of the RAAS (with an angiotensin converting enzyme (ACE) inhibitor plus a beta-blocker) both added-on to a thiazide diuretic, a calcium-channel blocker and an angiotensin receptor-1 blocker (ARB). Sequential nephron blockade consists in a progressive increase in sodium depletion using a thiazide diuretic, an aldosterone-receptor blocker, furosemide and, finally, amiloride.

On the other hand, the dual blockade of the RAAS consists of the progressive addition of an ACE inhibitor until the maximum dose and then the administration of a beta-blocker until the maximum dose. The primary outcomes will be reductions in the systolic BP, diastolic BP, mean BP and pulse pressure (PP) after 20 weeks of treatment. The secondary outcomes will evaluate treatment safety and tolerability, biochemical changes, evaluation of renal function and recognition of hypotension (ambulatory BP monitoring (ABPM)). The sample size was calculated assuming an alpha error of 5% to reject the null hypothesis with a statistical power of 80% giving a total of 40 individuals per group.

Discussion

In recent years, the cost of resistant hypertension (RH) treatment has increased. Thus, identifying the contribution of intravascular volume and serum renin in maintaining BP levels could help tailor more effective hypertension treatment, whether by acting on the control of intravascular volume or sodium balance, or by acting on the effects of the RAAS on the kidney.
