A comprehensive review of an unmet public health issue: resistant hypertension

Resistant hypertension is an intractable problem to patients and physicians. In recent decades, a substantial amount of basic and epidemiological studies provide us a vast number of valuable evidence and information about this once elusive disease. Better understanding about this entity could help physicians improve diagnostic and therapeutic accuracy. In present review, therefore, we first will detail the definition and diagnosis of resistant hypertension between cardiology societies, and followed by the information of prevalence of resistant hypertension around the world, and then briefly discuss currently used different nomenclature of resistant hypertension, and finally present diagnostic and therapeutic strategies of resistant hypertension

Lagging behind the Western countries: the knowledge gaps of gender differences in heart failure in Asia

Abstract Gender differences in heart failure (HF), ranging from epidemiological and pathophysiological factors to therapeutic response and prognosis, have been well documented in Western countries, especially in Europe and North America. The above gender differences in HF found in Westerners are rarely investigated in Asians. In this review, we explore the worrying knowledge gap on the gender differences in HF that existed in Asia in contrast with Western populations based on the following four aspects: epidemiology, risk factors, therapy, and prognosis. Finally, we conclude that investigations of gender differences in HF in Asia lag behind those in Europe and North America. Future work is required to establish and better use the high‐level, population‐based cohorts and develop our own high‐quality, convincing clinical trials to deliver robust gender‐specific conclusions in Asia

Correlation of left ventricular longitudinal strain and E/e’ ratio in primary hypertension patients

Objectives: The aim of this study is to explore and compare the relationships of both global longitudinal strain (GLS) and strain (SR) with E/e’ ratio in a population of asymptomatic patients with systemic hypertension. Methods: Retrospectively included 210 cases of essential hypertension patients. Dynamic images were analyzed for left ventricular myocardial systolic global longitudinal strain (GLS), left ventricular longitudinal peak systolic strain rate (SRs), early diastolic peak strain rate (SRe), late diastolic peak strain rate (SRa). According to the 2012 baseline E/e’ ratio, the population was divided into three groups, group A (E/e’14). Results: Systolic function parameters left ventricular ejection fraction (LVEF) remained at normal rage and no different, but patients with elevated E/e’ ratio had significantly lower GLS, lower early diastolic strain rate(SRe), lower ratio of early diastolic strain rate to late diastolic strain rate (SRe/a) and higher E/SRe. Positive relationships were observed between GLS, E/SRe and E/e’ ratio, inverse relationships were observed between SRe, SRe/a and E/e’ ratio. E/SRe >0.73 had a sensitivity of 87.7% and a specificity of 38.2% for predicting an elevated E/e’ ratio (E/e’>14). In multivariable analysis, IVS-e’ <7 cm/s showed almost 2.5-fold increased risk for decreased GLS (OR 2.48[95% CI 1.36–4.53]; p = 003). Conclusions: Our current study demonstrated that hypertensive patients with preserved LVEF and elevated E/e’ ratio have systolic and diastolic abnormalities in longitudinal directions as detected by speckle imaging. E/SRe correlates well with E/e’ and predicted elevated left ventricular filling pressure

Longitudinal Trajectories of Alcohol Consumption with All-Cause Mortality, Hypertension, and Blood Pressure Change: Results from CHNS Cohort, 1993&ndash;2015

Background: Previous studies have demonstrated a J-shaped association of alcohol consumption with all-cause mortality and hypertension, but the majority of these studies focus on a single measurement of alcohol intake and were conducted in a Western population. Whether long-term trajectories of alcohol consumption are associated with all-cause mortality, hypertension, and a change in blood pressure remains to be elucidated. Methods: In the large, population-based China Health and Nutrition Survey cohort from between 1993 and 2015, group-based trajectory modeling was conducted to identify distinct alcohol-consumption trajectory classes. We investigated their association with all-cause mortality and hypertension using Cox regression and binary logistics regression models. A restricted cubic spline was performed to determine the nonlinear relationships of mean alcohol intake with mortality and hypertension. Multivariate-adjusted generalized linear mixed-effects models were conducted to assess the change in blood pressure among alcohol-consumption trajectory classes. Results: Among the 5298 participants, 48.4% were women and the mean age was 62.6 years. After 22 years of follow-up, 568 (10.7%) of the participants died and 1284 (24.2%) developed hypertension. Long-term light and moderate drinkers had a lower risk of death than the non-drinkers, and a restricted cubic spline showed a J-shaped relationship between mean alcohol intake and mortality. Although blood pressure increased slower in light and moderate drinkers, a reduced risk of hypertension was only observed in the former. The long-term heavy drinkers had the highest blood pressure and death rate. Conclusions: Light alcohol intake might be protective even in the long run, while heavy drinking reversed the beneficial effect. The causality of such a connection needs to be further investigated

Incorporating uric acid into the CHA2DS2-VASc score improves the prediction of new-onset atrial fibrillation in patients with acute myocardial infarction

Abstract Background New-onset atrial fibrillation (NOAF) is a common cardiac arrhythmia observed in patients with acute myocardial infarction (AMI) and is associated with worse outcomes. While uric acid has been proposed as a potential biomarker for predicting atrial fibrillation, its association with NOAF in patients with AMI and its incremental discriminative ability when added to the CHA2DS2-VASc score are not well established. Methods We conducted a retrospective analysis of 1000 consecutive patients with AMI without a history of atrial fibrillation between January 2018 and December 2020. Continuous electrocardiographic monitoring was performed during the patients’ hospital stay to detect NOAF. We assessed the predictive ability of the different scoring models using receiver operating characteristic (ROC) curves. In addition, we employed the area under the curve (AUC), integrated discrimination improvement (IDI), and net reclassification improvement (NRI) analyses to assess the incremental discriminative ability of uric acid when added to the CHA2DS2-VASc score. Results Ninety-three patients (9.3%) developed NOAF during hospitalisation. In multivariate regression analyses, the adjusted odds ratio (OR) for NOAF was 1.439 per one standard deviation increase in uric acid level (95% confidence intervals (CI):1.182–1.753, p < 0.001). The ROC curve analysis revealed that the AUC for uric acid was 0.667 (95% CI:0.601–0.719), while the AUC for the CHA2DS2-VASc score was 0.678 (95% CI:0.623–0.734). After integrating the uric acid variable into the CHA2DS2-VASc score, the combined score yielded an improved AUC of 0.737 (95% CI:0.709–0.764, p = 0.009). Furthermore, there was a significant improvement in both IDI and NRI, indicating an incremental improvement in discriminative ability (IDI = 0.041, p < 0.001; NRI = 0.627, p < 0.001). Conclusion Our study suggests that uric acid level is an independent risk factor for the development of NOAF after AMI. Furthermore, the incorporation of uric acid into the CHA2DS2-VASc score significantly improves the discriminative ability of the score in identifying patients at high risk for NOAF

Association between triglyceride glucose‐body mass index and hypertension in Chinese adults: A cross‐sectional study

Abstract The triglyceride glucose‐body mass index (TyG‐BMI) has been considered an alternative marker of insulin resistance (IR). This cross‐sectional study was designed to mainly investigate the association between TyG‐BMI, triglyceride glucose combined with body mass index, and hypertension in Chinese adults. The relationship between TyG‐BMI and hypertension was examined by multivariate logistic regression and restricted cubic spline model. Multiple logistic regression models were also performed to examine the associations between the individual components of TyG‐BMI (BMI, TyG index, TG and FBG) and hypertension. The incremental ability of TyG‐BMI versus its individual components for hypertension discrimination was evaluated by C‐statistic and net reclassification index. Subgroup analysis was performed to examine potential interactions. A total of 92,545 participants (38.9% men, mean age 53.7 years) were included for final analysis. Logistic regression models showed TyG‐BMI and its individual components were all significantly associated with the odds of hypertension (p for trend < .001). The restricted cubic spline regression manifested a linear association between TyG‐BMI and hypertension (p for non‐linear = .062). The addition of TyG‐BMI, in comparison with each individual component, exhibited the maximum incremental value for the discrimination of hypertension on the basis of base model (C‐statistic: 0.679, 95% CI: 0.675‐0.683 for base model vs. 0.695, 95% CI: 0.691‐0.699 for base model + TyG‐BMI; net reclassification index: 0.226, 95% CI: 0.215‐0.234). TyG‐BMI was significantly associated with the odds of hypertension and can be a better discriminator of hypertension

Prognostic value of tissue Doppler E/e' ratio in hypertension patients with preserved left ventricular ejection fraction

Objectives: This study aims to investigate the association of tissue Doppler E/e' with cardiac events in hypertension patients, independent of and incremental to clinical and left ventricular geometric patterns. Methods: We retrospectively enrolled 222 asymptomatic nonischemic patients with hypertension who had echocardiogram in 2012 to evaluate tissue Doppler E/e'. Patients were followed up for cardiac events (cardiac events were defined as myocardial infarction, coronary revascularization procedures, new-onset angina (stable or unstable), heart failure). A cox regression was used to assess the association of the ratio of transmitral Doppler early filling velocity to tissue Doppler early diastolic mitral annular velocity (E/e') with cardiac events. Results: A total of 222 patients were included in analysis. There were 10 primary cardiac events during 3.2 ± 0.4 years follow-up. The E/e' ratio was the strongest predictor of cardiac events in Cox-proportional hazards models. Following adjustment for covariates, a unit rise in the E/e' ratio was associated with a 26% increment in risk of a cardiac event (HR 1.26, CI 1.06–1.50, p = 0.008). When E/e' ＞14 the hazard ratio of cardiac event was significantly increased compared with E/e' ≤ 14 in Kaplan–Meier analysis (log-rank ratio, 16.26; p ＜ 0.001). Conclusions: E/e', a non-invasive estimate of left ventricular filling pressure, predicts cardiac events in hypertensive population with preserved left ventricular ejection fraction, independent of and incremental to clinical and left ventricular geometric patterns. E/e' represents an early, effective tool for cardiovascular risk stratification in hypertension population

Age‐related alterations in cardiac and arterial structure and function in hypertensive women and men

Abstract The study was to compare age‐related alterations in cardiac and arterial structure and function by sex and to explore the impacts of achieved systolic blood pressure (SBP; <130 mm Hg vs. <140 mm Hg) level on age‐related alterations in cardiac and arterial structure and function in hypertensive women and men. Community hypertensive individuals without cardiovascular disease who had echocardiographic examination were included. Age‐related alterations in cardiac and arterial structure and function were compared by sex, and interplay between age and sex was analyzed according to achieved SBP level. The mean age of the cohort was 66.5 years, and women accounted for 62% (n = 602) of the cohort (n = 971). Compared to men, women had worse left ventricular (LV) diastolic function and greater LV and arterial stiffness. After adjusting for covariates, the magnitude of the associations between age with septal E/e′ ratio, septal S′ velocity, effective arterial elastance (Ea) and LV end‐diastolic elastance (Eed) were greater in women. Sex differences in the magnitude of association between age with these four indices varied according to achieved SBP level. When achieved SBP <130 mm Hg, the magnitude of the associations between age with septal E/e′ ratio, septal S′ velocity, Ea and Eed did not differ by sex. Since age and sex are non‐modifiable, achieving SBP target, especially at a lower level, might be beneficial to attenuate sex differences in age‐related alterations in cardiac and arterial structure and function

Left atrial volume index is superior to left atrial diameter index in relation to coronary heart disease in hypertension patients with preserved left ventricular ejection fraction

Objective: Research hypothesis is that left atrial (LA) volume index is superior to LA diameter index for coronary heart disease and LA volume index is important to refine risk stratification. Methods: We retrospectively enrolled 222 asymptomatic non-ischemic patients with hypertension who had stored digital images in 2012. Patients were followed up for coronary heart disease over a median of 3.2 years. The Area under receiver operating characteristic curve for LA parameters with coronary heart disease was evaluated. Cox regression was used to assess the association between left atrial parameters and coronary heart disease. Results: The mean age of patients was 62 years, 45% were men, and mean left atrial diameter, mean left atrial volume, mean LA diameter index, mean LA volume index was 32 mm, 43 ml, 21 mm/m2, 27 ml/m2, respectively. After 3.2 years follow up, 10 patients experienced coronary heart disease. Compared with patients without coronary heart disease, LA diameter index and LA volume index increased in coronary heart disease group (P < 0.05). Multivariate cox regression analysis showed, adjusted for age, sex, smoking, cholesterol, fasting plasma glucose, diabetes, systolic blood pressure, left ventricular mass index, and E/e’ ratio, a unit rise in LA volume index was associated with a 15% increase in the risk of coronary heart disease. (HR:1.155; 95% CI 1.002–1.332). Compared with LA diameter index, the area under receiver operating characteristic curve values for predicting coronary heart disease were higher for LA volume index (0.797). Conclusions: Our study showed that LA volume index was superior to LA diameter index. LA volume index had independent prognostic implications in terms of coronary heart disease prediction in hypertension patients with preserved left ventricular ejection fraction
