Ups and downs of conducting a national representative survey on hypertension during pandemic time: main results of SEPHAR IV.

OBJECTIVES: This national representative survey sought to assess hypertension's prevalence, awareness, treatment and control in Romania. METHODS: A representative sample (by age, sex and residence) of 1477 Romanian adults (51.19 ±â€Š16.61 years, range 18-80 years, 59.9% women) was multimodally evaluated during two study visits. Hypertension was defined as SBP at least 140 mmHg and/or DBP at least 90 mmHg or previously diagnosed hypertension, regardless of BP. Awareness was defined by knowledge of previous hypertension diagnosis or of current use of antihypertensive treatment. Treatment was defined by antihypertensive medication taken at least 2 weeks prior to enrolment. Control was defined as SBP less than 140 mmHg and DBP less than 90 mmHg at both visits in treated hypertensive patients. RESULTS: Hypertension prevalence was 46% ( n  = 680) consisting of 81.02% ( n  = 551) known hypertensive patients and 18.98% ( n  = 129) newly diagnosed hypertensive patients. Awareness, treatment and control of hypertension were: 81% ( n  = 551), 83.8% ( n  = 462) and 39.2% ( n  = 181). CONCLUSION: Despite numerous pandemic-related obstacles in conducting a national survey, SEPHAR IV updates hypertension epidemiological data of a high-cardiovascular-risk Eastern-European population. This study confirms previous predictions of hypertension prevalence, treatment and control, which remain unfavourable because of unsatisfactory control of promoting factors.

Social and Metabolic Determinants of Prevalent Hypertension in Men and Women: A Cluster Analysis from a Population-Based Study.

Essential hypertension (HTN) has a complex spectrum of pathophysiological determinants and current guidelines provide limited information on high-risk groups that should be targeted for its primary prevention. The objective of our research was to identify clusters of social and metabolic factors associated with prevalent HTN in men and women from a population-based survey in Romania. Of the 1477 participants in the main study, 798 with complete data were analyzed here. Using two-step cluster analysis, one high-risk cluster in women and two high and intermediate risk for prevalent HTN in men were identified. Older age, rural area, lower education, and higher burden of metabolic factors characterized clusters with higher risk, while intermediate risk in men was characterized by a more metabolically healthy phenotype in younger individuals. In logistic regression, men in Cluster 1 vs. those in Cluster 3 had an odds ratio (OR) of 9.6 (95%CI: 4.6; 20.0), p < 0.001 for prevalent HTN, while OR for Cluster 2 vs. Cluster 3 was 3.2 (95%CI: 1.4; 7.4), p = 0.005. In women, the OR for HTN was 10.2 (95%CI: 5.7; 18.5) if assigned to Cluster 2 vs. Cluster 1, p < 0.001. These results pointed out the subgroups and communities that the primary prevention of HTN should be prioritized in.

The Importance of a New Cardiovascular Risk Factor - Asymmetric Dimethylarginine.

In the past years, scientific research has highlighted the presence of a new cardiovascular risk factor, the implications of which have not been sufficiently studied so far. It is different from conventional risk factors because it acts independently at the endothelial level, having important proatherogenic properties. Through its action, this risk factor leads to increased oxidative stress and promotes the onset of atherosclerosis faster than other well-known risk factors so far. Asymmetric dimethylarginine (ADMA) is a methylprotein that arises from posttranslational methylation of proteins. Its importance has emerged in recent years, when the rate of cardiovascular mortality among patients with chronic kidney disease has been high. The distinctive element of this risk factor compared to other well-known ones is given by its ability to compete directly with nitric oxide synthase, being its strongest endogenous inhibitor, with strong proatherogenic attributions. Given that ADMA has tight correlations with atherogenesis and endothelial damage, its assessment should be taken into consideration for any patient who has been recently diagnosed with high blood pressure.

Acute kidney injury: a clinical issue in hospitalized patients with heart failure with mid-range ejection fraction.

INTRODUCTION Acute kidney injury (AKI) during hospitalization is associated with increased mortality in patients with acute heart failure (AHF). In 2016, the European Society of Cardiology introduced the category of heart failure (HF) with mid­range ventricular ejection fraction (HFmrEF) as a distinct category from HF with preserved ejection fraction (HFpEF) and reduced ejection fraction (HFrEF). OBJECTIVES The aim of this study was to evaluate in­hospital mortality risk associated with AKI in patients with AHF, with a focus on the HFmrEF group. PATIENTS AND METHODS A total of 365 health records of patients with a primary diagnosis of acute decompensated heart failure (ADHF) were reviewed. AKI was defined according to Acute Kidney Injury Network criteria. HF was diagnosed based on Framingham criteria. Patients with ADHF were evaluated as 3 separate groups, based on ventricular ejection fraction: HFpEF (≥50%), HFmrEF (40%-49%), and HFrEF (<40%). Risk and survival analyses were conducted on de­identified data. RESULTS The AKI­associated in­hospital mortality odds ratios for HFmrEF and HFrEF groups were 4.55 (95% CI, 1.46-14.18) and 2.59 (95% CI, 1.05-6.41), respectively, with a highly significant difference between the groups (P = 0.002; Mantel-Haenszel test). The hazard ratios in the Cox proportional hazards model were 4.79 (95% CI, 1.54-14.96) and 2.94 (95% CI, 1.27-6.80) for HFmrEF and HFrEF groups, respectively. CONCLUSIONS AKI was associated with a higher risk of mortality in patients with HFmrEF when compared with those with HFrEF, suggesting a stronger prognostic impact of AKI in patients with HFmrEF.

Galectin-3: A Link between Myocardial and Arterial Stiffening in Patients with Acute Decompensated Heart Failure? / Galectina-3: Ligação entre Rigidez Miocárdica e Arterial em Pacientes com Insuficiência Cardíaca Descompensada?

Abstract Background: Heart failure is accompanied by abnormalities in ventricular-vascular interaction due to increased myocardial and arterial stiffness. Galectin-3 is a recently discovered biomarker that plays an important role in myocardial and vascular fibrosis and heart failure progression. Objectives: The aim of this study was to determine whether galectin-3 is correlated with arterial stiffening markers and impaired ventricular-arterial coupling in decompensated heart failure patients. Methods: A total of 79 inpatients with acute decompensated heart failure were evaluated. Serum galectin-3 was determined at baseline, and during admission, transthoracic echocardiography and measurements of vascular indices by Doppler ultrasonography were performed. Results: Elevated pulse wave velocity and low arterial carotid distensibility are associated with heart failure in patients with preserved ejection fraction (p = 0.04, p = 0.009). Pulse wave velocity, carotid distensibility and Young’s modulus did not correlate with serum galectin-3 levels. Conversely, raised galectin-3 levels correlated with an increased ventricular-arterial coupling ratio (Ea/Elv) p = 0.047, OR = 1.9, 95% CI (1.0‑3.6). Increased galectin-3 levels were associated with lower rates of left ventricular pressure rise in early systole (dp/dt) (p=0.018) and raised pulmonary artery pressure (p = 0.046). High galectin-3 levels (p = 0.038, HR = 3.07) and arterial pulmonary pressure (p = 0.007, HR = 1.06) were found to be independent risk factors for all-cause mortality and readmissions. Conclusions: This study showed no significant correlation between serum galectin-3 levels and arterial stiffening markers. Instead, high galectin-3 levels predicted impaired ventricular-arterial coupling. Galectin-3 may be predictive of raised pulmonary artery pressures. Elevated galectin-3 levels correlate with severe systolic dysfunction and together with pulmonary hypertension are independent markers of outcome.

Resumo Fundamento: A insuficiência cardíaca é acompanhada por anormalidades na interação ventrículo-vascular devido à rigidez miocárdica e arterial aumentada. A galectina-3 é um biomarcador recentemente descoberto que exerce um importante papel na fibrose miocárdica e vascular, e na progressão da insuficiência cardíaca. Objetivos: O objetivo deste estudo foi determinar se a galectina-3 está correlacionada com marcadores de rigidez arterial e acoplamento ventriculoarterial deficiente em pacientes com insuficiência cardíaca descompensada. Métodos: Um total de 79 pacientes internados com insuficiência cardíaca descompensada foi avaliado. Galectina-3 sérica basal foi determinada e, durante a admissão hospitalar, foram realizadas ecocardiografia transtorácica e medidas de índices vasculares por ultrassonografia Doppler. Resultados: Velocidade de onda de pulso elevada e baixa distensibilidade da artéria carótida estão associadas com insuficiência cardíaca em pacientes com fração de ejeção preservada (p = 0,04, p = 0,009). Velocidade de pulso, distensibilidade da artéria carótida e módulo de Young não se correlacionaram com níveis séricos de galectina-3. Por outro lado, níveis elevados de galectina-3 correlacionaram com razão de acoplamento ventriculoarterial aumentada (Ea/Elv) p = 0,047, OR = 1,9, IC 95% (1,0-3,6). Níveis aumentados de galectina-3 estavam associados com taxas mais baixas de pressão ventricular esquerda na fase inicial da sístole (dp/dt) (p = 0,018), e pressão arterial pulmonar aumentada (p = 0,046). Os resultados mostraram que níveis elevados de galectina-3 (p = 0,038, HR = 3,07) e pressão pulmonar arterial (p = 0,007, HR = 1,06) são fatores de risco independentes para mortalidade de todas as causas e reinternações hospitalares. Conclusões: O estudo mostrou que não houve correlação significativa entre níveis séricos de galectina-3 e marcadores de rigidez arterial. Altos níveis de galectina-3, por outro lado, foi um preditor de acoplamento ventriculoarterial deficiente. A galectina-3 pode ser um preditor de pressões arteriais pulmonares aumentadas. Níveis elevados de galectina-3 correlacionam-se com disfunção sistólica grave e, juntamente com hipertensão pulmonar, é um marcador independente de desfecho.

Galectin-3 in heart failure pathology--"another brick in the wall"?

Heart failure is a disease affecting millions of patients each year, and is responsible for burdening the world with high mortality rates. More concerns come from its numerous hospital readmissions (with an estimated number of 2.6 million per year which makes it one of the leading diseases responsible for national healthcare expenditures). Despite drastic improvement of therapies in recent years, heart failure remains a progressive disease. Thus, more attention has been given to finding potential biomarkers involved in the pathological mechanisms of this disease that would potentially lead to faster diagnosis and improved prognosis. One of the emerging biomarkers that has just recently come into the spotlight is galectin-3. It was associated in recent clinical trials with both the progression and severity of heart failure. Ventricular remodelling and myocardial fibrosis are essential for heart failure development and are linked to poor outcomes. An ever-growing body of evidence places galectin-3 as an important link between inflammation and fibrosis, which play a prominent role in cardiac remodelling.This review sums up the most relevant experimental and clinical studies about galectin-3 and its potential prognostic value in heart failure. The article also provides a better understanding of this molecule's involvement in heart failure pathology by modulating cardiac fibrosis. It also weighs whether the available data on galectin-3 are consistent enough to reduce readmissions and mortality while improving diagnosis and future therapies for heart failure, versus the possibility that it is simply"another brick in the wall?"

Prognosis and treatment of atrial fibrillation patients by European cardiologists: one year follow-up of the EURObservational Research Programme-Atrial Fibrillation General Registry Pilot Phase (EORP-AF Pilot registry).

BACKGROUND: The EURObservational Research Programme-Atrial Fibrillation General Registry Pilot Phase (EORP-AF Pilot) provides systematic collection of contemporary data regarding the management and treatment of 3119 subjects with AF from 9 member European Society of Cardiology (ESC) countries. In this analysis, we report the development of symptoms, use of antithrombotic therapy and rate vs. rhythm strategies, as well as determinants of mortality and/or stroke/transient ischaemic attack (TIA)/peripheral embolism during 1-year follow-up in this contemporary European registry of AF patients. METHODS: The registry population comprised consecutive in- and out-patients with AF presenting to cardiologists in participating ESC countries. Consecutive patients with AF documented by ECG were enrolled. Follow-up was performed by the local investigator, initially at 1 year, as part of a long-term cohort study. RESULTS: At the follow-up, patients were frequently asymptomatic (76.8%), but symptoms are nevertheless common among paroxysmal and persistent AF patients, especially palpitations, fatigue, and shortness of breath. Oral anticoagulant (OAC) use remains high, ∼78% overall at follow-up, and of those on vitamin K antagonist (VKA), 84% remained on VKA during the follow-up, while of those on non-VKA oral anticoagulant (NOAC) at baseline, 86% remained on NOAC, and 11.8% had changed to a VKA and 1.1% to antiplatelet therapy. Digitalis was commonly used in paroxysmal AF patients. Of rhythm control interventions, electrical cardioversion was performed in 9.7%, pharmacological cardioversion in 5.1%, and catheter ablation in 4.4%. Despite good adherence to anticoagulation, 1-year mortality was high (5.7%), with most deaths were cardiovascular (70%). Hospital readmissions were common, especially for atrial tachyarrhythmias and heart failure. On multivariate analysis, independent baseline predictors for mortality and/or stroke/TIA/peripheral embolism were age, AF as primary presentation, previous TIA, chronic kidney disease, chronic heart failure, malignancy, and minor bleeding. Independent predictors of mortality were age, chronic kidney disease, AF as primary presentation, prior TIA, chronic obstructive pulmonary disease, malignancy, minor bleeding, and diuretic use. Statin use was predictive of lower mortality. CONCLUSION: In this 1-year follow-up analysis of the EORP-AF pilot general registry, we provide data on the first contemporary registry focused on management practices among European cardiologists, conducted since the publication of the new ESC guidelines. Overall OAC use remains high, although persistence with therapy may be problematic. Nonetheless, continued OAC use was more common than in prior reports. Despite the high prescription of OAC, 1-year mortality and morbidity remain high in AF patients, particularly from heart failure and hospitalizations.
