Anticoagulation Status and Left Atrial Appendage Occlusion Indications in Hospitalized Cardiology Patients with Atrial Fibrillation: A Hellenic Cardiorenal Morbidity Snapshot (HECMOS) Sub-Study.

Background and Objectives: The proper use of oral anticoagulants is crucial in the management of non-valvular atrial fibrillation (AF) patients. Left atrial appendage closure (LAAC) may be considered for stroke prevention in patients with AF and contraindications for long-term anticoagulant treatment. We aimed to assess anticoagulation status and LAAC indications in patients with AF from the HECMOS (Hellenic Cardiorenal Morbidity Snapshot) survey. Materials and Methods: The HECMOS was a nationwide snapshot survey of cardiorenal morbidity in hospitalized cardiology patients. HECMOS used an electronic platform to collect demographic and clinically relevant information from all patients hospitalized on 3 March 2022 in 55 different cardiology departments. In this substudy, we included patients with known AF without mechanical prosthetic valves or moderate-to-severe mitral valve stenosis. Patients with prior stroke, previous major bleeding, poor adherence to anticoagulants, and end-stage renal disease were considered candidates for LAAC. Results: Two hundred fifty-six patients (mean age 76.6 ± 11.7, 148 males) were included in our analysis. Most of them (n = 159; 62%) suffered from persistent AF. The mean CHA2DS2-VASc score was 4.28 ± 1.7, while the mean HAS-BLED score was 1.47 ± 0.9. Three out of three patients with a a CHA2DS2-VASc score of 0 or 1 (female) were inappropriately anticoagulated. Sixteen out of eighteen patients with a CHA2DS2-VASc score 1 or 2 (if female) received anticoagulants. Thirty-one out of two hundred thirty-five patients with a CHA2DS2-VASc score > 1 or 2 (if female) were inappropriately not anticoagulated. Relative indications for LAAC were present in 68 patients with NVAF (63 had only one risk factor and 5 had two concurrent risk factors). In detail, 36 had a prior stroke, 17 patients had a history of major bleeding, 15 patients reported poor or no adherence to the anticoagulant therapy and 5 had an eGFR value < 15 mL/min/1.73 m2 for a total of 73 risk factors. Moreover, 33 had a HAS-BLED score ≥ 3. No LAAC treatment was recorded. Conclusions: Anticoagulation status was nearly optimal in a high-thromboembolic-risk population of cardiology patients who were mainly treated using NOACs. One out of four AF patients should be screened for LAAC.

Long-term efficacy and safety of renal denervation: an update from registries and randomised trials.

Hypertension remains the leading treatable global cause of mortality due to high incidence and poor control rates despite of safe and effective drug therapy.Animal studies do not support functional nerve regrowth after RF-RDN and accordingly clinical evidence verify that RDN leads to durable BP reduction.Renal denervation is safe, as up to 36 months after the procedure, there are no statistically significant difference in procedure-related adverse events, deterioration of renal function and adverse cardiovascular outcomeRenal denervation is efficient in reducing BP in patients with no drug therapy, independently of the number of antihypertensive drugs and phenotype of patient. This sustained and safe reduction in BP observed up to 36 months after RDN could be associated with lower rates of renal and cardiovascular events.

LOX-1 Receptor: A Diagnostic Tool and Therapeutic Target in Atherogenesis.

Low-density lipoprotein (LDL) and oxidized LDL (oxLDL) are major contributors to atherogenesis, as endogenous antigens, via several receptors such as LOX 1. A PubMed search was conducted in order to identify relevant articles regarding LOX-1's role in the atherosclerosis, diagnosis, prognostic use and molecules that could be used for therapy. The references of the manuscripts obtained were also reviewed, in order to find additional relevant bibliography. LOX-1 is a lectin-like pattern recognition receptor, mostly expressed in endothelial cells (ECs) which can bind a variety of molecules, including oxLDL and C-reactive protein (CRP). LOX-1 plays a key role in oxLDL's role as a causative agent of atherosclerosis through several pathologic mechanisms, such as oxLDL deposition in the subintima, foam cell formation and endothelial dysfunction. Additionally, LOX-1 acts a scavenger receptor for oxLDL in macrophages and can be responsible for oxLDL uptake, when stimulated. Serum LOX-1 (sLOX-1) has emerged as a new, potential biomarker for diagnosis of acute coronary syndromes, and it seems promising for use along with other common biomarkers in everyday clinical practice. In a therapeutic perspective, natural as well as synthetic molecules exert anti-LOX-1 properties and attain the receptor's pathophysiological effects, thus extensive research is ongoing to further evaluate molecules with therapeutic potential. However, most of these molecules need further trials in order to properly assess their safety and efficacy for clinical use. The aim of this review is to investigate LOX-1 role in atherogenesis and explore its potential as diagnostic tool and therapeutic target.

Transcatheter Structural Heart Interventions in the Acute Setting: An Emerging Indication.

Structural heart disease is increasingly prevalent in the general population, especially in patients of increased age. Recent advances in transcatheter structural heart interventions have gained a significant following and are now considered a mainstay option for managing stable valvular disease. However, the concept of transcatheter interventions has also been tested in acute settings by several investigators, especially in cases where valvular disease comes as a result of acute ischemia or in the context of acute decompensated heart failure. Tested interventions include both the mitral and aortic valve, mostly evaluating mitral transcatheter edge-to-edge repair and transcatheter aortic valve implantation, respectively. This review is going to focus on the use of acute structural heart interventions in the emergent setting, and it will delineate the available data and provide a meaningful discussion on the optimal patient phenotype and future directions of the field.

Atrial Functional Mitral Regurgitation: From Diagnosis to Current Interventional Therapies.

Mitral regurgitation (MR) is one of the most common valvular pathologies worldwide, contributing to the morbidity and mortality of several cardiovascular pathologies, including heart failure (HF). Novel transcatheter treatment for MR has given the opportunity for a safe and feasible alternative, to surgery, in order to repair the valve and improve patient outcomes. However, after the results of early transcatheter edge-to-edge repair (TEER) trials, it has become evident that subcategorizing the mitral regurgitation etiology and the left ventricular function, in patients due to undergo TEER, is of the essence, in order to predict responsiveness to treatment and select the most appropriate patient phenotype. Thus, a novel MR phenotype, atrial functional MR (AFMR), has been recently recognized as a distinct pathophysiological entity, where the etiology of the regurgitation is secondary to annular dilatation, in a diseased left atrium, with preserved left ventricular function. Recent studies have evaluated and compared the outcomes of TEER in AFMR with ventricular functional MR (VFMR), with the results favoring the AFMR. In specific, TEER in this patient substrate has better echocardiographic and long-term outcomes. Thus, our review will provide a comprehensive pathogenesis and mechanistic overview of AFMR, insights into the echocardiographic approach of such patients and pre-procedural planning, discuss the most recent clinical trials and their implications for future treatment directions, as well as highlight future frontiers of research in the setting of TEER and transcatheter mitral valve replacement (TMVR) in AFMR patients.

Proprotein Convertase Subtilisin/Kexin Type 9 Inhibitors in Patients Following Acute Coronary Syndromes: From Lipid Lowering and Plaque Stabilization to Improved Outcomes.

Lipid lowering, with the use of statins after an acute coronary syndrome (ACS), is a cornerstone, well-established strategy for the secondary prevention of ischemic events in this high-risk cohort. In addition to the positive effect on lipid levels, statins have also been linked to improved atherosclerotic plaque characteristics, such as plaque regression and inflammation reduction, associated with the extent of reduction in LDL-C. The recent emergence of PCSK9 inhibitors for the management of dyslipidemia and the more extensive lipid lowering provided by these agents may provide better prevention for ACS patients when initiated after the ACS event. Several trials have evaluated the immediate post-ACS initiation of PCSK9 inhibitors, which has shown, to date, beneficial results. Furthermore, PCSK9 inhibitors have been linked with positive plaque remodeling and associated mortality benefits, which makes their use in the initial management strategy of such patients appealing. Therefore, in this review, we will analyze the rationale behind immediate lipid lowering after an ACS, report the evidence of PCSK9 inhibition immediately after the ACS event and the available data on plaque stabilization, and discuss treatment algorithms and clinical perspectives for the use of these agents in this clinical setting.

Efficacy of Chronic Use of Sodium-Glucose Co-transporter 2 Inhibitors on the Prevention of Contrast-Induced Acute Kidney Injury in Patients with Type 2 Diabetes Mellitus Following Coronary Procedures: A Systematic Review and Meta-Analysis.

INTRODUCTION: Contrast-induced acute kidney injury (CI-AKI) is a common complication of iodinated contrast administration during coronary procedures, especially in patients with diabetes mellitus (DM). Besides periprocedural hydration and statins, there are no other pharmacological strategies with consistent results to prevent CI-AKI up to date. This study aims to evaluate the efficacy of chronic use of sodium-glucose co-transporter 2 (SGLT2) inhibitors on the prevention of CI-AKI in patients with type 2 DM following coronary procedures. METHODS: A systematic literature search of MEDLINE, Google Scholar, Embase, and Cochrane Library was performed. Relevant observational studies and randomized controlled studies (RCTs) were identified. Results were pooled using a random-effect model meta-analysis. Subgroup analyses were performed to evaluate the potential benefit of SGLT2 inhibitors on the prevention of CI-AKI in patients undergoing urgent or elective coronary angiography/percutaneous coronary interventions (CAG/PCI). RESULTS: Seven observational studies and one randomized controlled trial with 2740 patients were included. Chronic treatment (minimum duration 2 weeks to 6 months) with an SGLT2 inhibitor was associated with a significantly reduced risk of CI-AKI in diabetic patients undergoing coronary procedures compared with the control group [risk ratio (RR) 0.48; 95% confidence interval (CI) 0.39-0.59; p < 0.001). Results of subsequent subgroup analysis showed a significant reduction in the incidence of CI-AKI in diabetic patients undergoing both elective CAG/PCI (RR 0.49; 95% CI 0.35-0.68; p<0.001) and urgent CAG/PCI (RR 0.48; 95% Cl 0.35-0.66; p < 0.001). DISCUSSION: Chronic use of SGLT2 inhibitors may be preventative against the incidence of CI-AKI in patients with type 2 DM undergoing coronary interventions. Further RCTs are needed to confirm our findings.

Transcatheter Structural Heart Disease Interventions and Concomitant Left Atrial Appendage Occlusion: A State of the Art Review.

Atrial fibrillation (AF) is the most common arrhythmia in patients with valvular heart disease, and it can be associated with adverse patient outcomes. However, the need for anticoagulation to counterbalance AF-associated stroke risk may further lead to suboptimal outcomes via increasing bleeding events, especially in high-risk individuals. Because the vast majority of thrombi occur in the left atrial appendage, left atrial appendage occlusion (LAAO) is an established procedure for preventing ischemic stroke in patients with AF, while limiting anticoagulation-related bleeding events. Thus, the concept of combining an index procedure for structural heart disease (SHD) with LAAO seems promising for preventing future stroke events. A combined procedure has been described in aortic stenosis (transcatheter aortic valve implantation + LAAO), mitral regurgitation (transcatheter edge-to-edge repair + LAAO), and atrial septal defects (patent foramen ovale/atrial septal defect + LAAO). Evidence shows that a combined procedure can be safely performed in a "1-stop shop" fashion, without increased rates of procedural adverse events, with the potential to limit bleeding risk and provide prophylaxis against stroke events. This review analyses indications and clinical evidence regarding the safety and efficacy of combined SHD+LAAO procedures, while also providing insights into gaps in knowledge and future directions for the evolution of this field.

ANOCA updated: From pathophysiology to modern clinical practice.

Lately, a large number of stable ischemic patients, with no obstructed coronary arteries are being diagnosed. Despite this condition, which is being described as angina with no obstructive coronary arteries (ANOCA), was thought to be benign, recent evidence report that it is associated with increased risk for adverse cardiovascular outcomes. ANOCA is more frequent in women and, pathophysiologically, it is predominantly related with microvascular dysfunction, while other factors, such as endothelial dysfunction, inflammation and autonomic nervous system seem to also play a major role to its development, while other studies implicate ANOCA and microvascular dysfunction in the pathogenesis of heart failure with preserved ejection fraction. For establishing an ANOCA diagnosis, measurement including coronary flow reserve (CFR), microvascular resistance (IMR) and hyperemic microvascular resistance (HMR) are mostly used in clinical practice. In addition, new modalities, such as optical coherence tomography (OCT) are being tested and show promising results for future diagnostic use. Regarding management, pharmacotherapy consists of a wide selection of drugs, according to the respected pathophysiology of the disease (vasospastic angina or microvascular dysfunction), while research for new treatment options including interventional techniques, is currently ongoing. This review, therefore, aims to provide a comprehensive analysis of all aspects related to ANOCA, from pathophysiology to clinical managements, as well as clinical implications and suggestions for future research efforts, which will help advance our understanding of the syndrome and establish more, evidence-based, therapies.

Hypothermia for Cardioprotection in Acute Coronary Syndrome Patients: From Bench to Bedside.

Early revascularization for patients with acute myocardial infarction (AMI) is of outmost importance in limiting infarct size and associated complications, as well as for improving long-term survival and outcomes. However, reperfusion itself may further damage the myocardium and increase the infarct size, a condition commonly recognized as myocardial reperfusion injury. Several strategies have been developed for limiting the associated with reperfusion myocardial damage, including hypothermia. Hypothermia has been shown to limit the degree of infarct size increase, when started before reperfusion, in several animal models. Systemic hypothermia, however, failed to show any benefit, due to adverse events and potentially insufficient myocardial cooling. Recently, the novel technique of intracoronary selective hypothermia is being tested, with preclinical and clinical results being of particular interest. Therefore, in this review, we will describe the pathophysiology of myocardial reperfusion injury and the cardioprotective mechanics of hypothermia, report the animal and clinical evidence in both systemic and selective hypothermia and discuss the potential future directions and clinical perspectives in the context of cardioprotection for myocardial reperfusion injury.

Management of dyslipidemia in coronary artery disease: the present and the future.

Coronary artery disease (CAD) remains a leading cause of global morbidity and mortality, necessitating continuous refinement in the management of dyslipidemia, one of its major risk factors, to mitigate cardiovascular risks. Previous studies have proven the critical role of immediate and robust low-density lipoprotein cholesterol (LDL-C) reduction in the aftermath of acute coronary syndrome (ACS). Emphasizing the evidence supporting this approach, we delve into the impact of early intervention on cardiovascular outcomes and propose optimal strategies for achieving rapid LDL-C lowering, while also providing the rationale for early proprotein convertase subtilisin/kexin 9 inhibitor use after an ACS. Given the importance of the residual lipidemic risk, we present an overview of emerging therapeutic avenues poised to reshape dyslipidemia management, such as bempedoic acid, lipoprotein(a) inhibition, ApoC3 modulation, and angiopoietin-like protein 3 targeting. This comprehensive review amalgamates current evidence with future prospects, offering a holistic perspective on the management of dyslipidemia in CAD. By exploring both the urgency for immediate post-ACS LDL-C reduction and the exciting advancements on the horizon, this article provides a roadmap for clinicians navigating the intricate landscape of lipid-lowering therapies in CAD.

Optimal management of high bleeding risk patients undergoing percutaneous coronary interventions: Where do we stand?

Percutaneous coronary interventions (PCI) are the mainstay of treating obstructive coronary artery disease. However, procedural planning and individualization of the procedure is necessary for different patient phenotypes to optimize outcomes. Specifically, post-PCI pharmacotherapy with antiplatelets complicates the management of patients at high bleeding risk due to comorbidities, such as atrial fibrillation. Aiming to limit post-procedural adverse events and reduce the procedure-related bleeding risk, several novel technologies and hypotheses have been tested in clinical practice. Such frontiers include limiting the duration of dual antiplatelet therapy or even prescribing single regimens, using drug-coated balloons for performing the intervention and the effect of imaging-guided PCI in optimizing stent expansion. Furthermore, specific instruction in different patient phenotypes, such as atrial fibrillation and chronic kidney disease, are emerging, as despite both pathologies being considered at high bleeding risk, one size does not fit all. Thus, our review will provide all the recent updates on the field as well as algorithms and expert opinions on how to manage this, particularly common, phenotype of patient.

Unravelling the effect of renal denervation on glucose homeostasis: more questions than answers?

Renal Denervation (RDN) is an interventional, endovascular procedure used for the management of hypertension. The procedure itself aims to ablate the renal sympathetic nerves and to interrupt the renal sympathetic nervous system overactivation, thus decreasing blood pressure (BP) levels and total sympathetic drive in the body. Recent favorable evidence for RDN resulted in the procedure being included in the recent European Guidelines for the management of Hypertension, while RDN is considered the third pillar, along with pharmacotherapy, for managing hypertension. Sympathetic overactivation, however, is associated with numerous other pathologies, including diabetes, metabolic syndrome and glycemic control, which are linked to adverse cardiovascular health and outcomes. Therefore, RDN, via ameliorating sympathetic response, could be also proven beneficial for maintaining an euglycemic status in patients with cardiovascular disease, alongside its BP-lowering effects. Several studies have aimed, over the years, to provide evidence regarding the pathophysiological effects of RDN in glucose homeostasis as well as investigate the potential clinical benefits of the procedure in glucose and insulin homeostasis. The purpose of this review is, thus, to analyze the pathophysiological links between the autonomous nervous system and glycemic control, as well as provide an overview of the available preclinical and clinical data regarding the effect of RDN in glycemic control.

Coronary sinus narrowing therapy: A "Reducer" for angina and beyond.

Refractory Angina (RA) is an increasingly common clinical diagnosis, in which patients unsuitable for further percutaneous or surgical procedures experience anginal symptoms, despite receiving optimal medical therapy. This clinical condition challenges the everyday activities and diminishes the quality of life of these patients. A wide variety of novel therapies for this type of angina are being investigated for clinical use. One of them is coronary sinus narrowing, which is performed as a percutaneous interventional procedure using catheter-delivered device, the Reducer. The device is implanted in the coronary sinus creating a physical narrowing and a pressure gradient in the sinus. This intervention improves the impaired blood flow in the ischemic regions of the heart leading to the relief of the anginal symptoms and, therefore, the overall clinical improvement of these patients. Several clinical trials have established both the safety and efficacy of the coronary sinus Reducer, while ongoing trials are aiming to further establish the procedure's safety and efficiency in both RA and other cardiovascular diseases, such as coronary microvascular dysfunction. This review aims to discuss the pathophysiology and the role of the coronary sinus Reducer in RA, the clinical trials documenting its safety and efficacy, as well as the future perspectives of this procedure among cardiovascular diseases.

A network meta-analysis of the antithrombotic strategies in patients with atrial fibrillation and percutaneous coronary interventions: Focus on bleeding.

BACKGROUND: We performed a network meta-analysis of randomized controlled trials comparing non-vitamin K antagonist oral anticoagulant (NOAC)-based versus vitamin K antagonists (VKA)-based regimens in patients with atrial fibrillation (AF) and acute coronary syndromes or PCI, aiming to examine the precise impact of recently established antithrombotic strategies on major bleeding as primary end-point and other safety and efficacy as secondary end-points. METHODS: A literature search was conducted for randomized controlled trials. Our search took place in three major databases. The primary endpoint of our study was bleeding. To combine direct and indirect evidence across trials, a frequentist network meta-analysis with a random-effects model was used. RESULTS: Five studies were found eligible for the meta-analysis enrolling a total of 11,542 patients. Five studies (N = 4903 patients) contributed to the network. Compared to the triple antithrombotic therapy (TAT)-based VKA, only the dual antithrombotic therapy (DAT) based NOAC reduced the bleeding (RR 0.57, 95%CI 0.40-0.82). There was no statistically significant difference between DAT-based VKA (RR = 0.66, 95%CI = 0.40-1.09) or TAT-based NOAC (RR = 0.80, 95%CI = 0.43-1.49). DAT-based NOAC ranked best (P-score = 0.91), followed by DAT-based VKA (P-score = 0.67), TAT-based NOAC (P-score = 0.40), and TAT-based VKA (P-score = 0.03). CONCLUSION: The network meta-analysis of four antithrombotic strategies, demonstrated that in patients with AF undergoing PCI the combination of DAT-based NOAC is associated with a significantly lower risk of major bleeding events. This strategy does not seem to be less effective in terms of prevention of ischemic events compared to the other regimens.

Transcatheter Tricuspid Valve Interventions: A Triumph for Transcatheter Procedures?

Tricuspid regurgitation (TR) is a common valvular pathology, estimated to affect 1.6 million people in the United States alone. Even though guidelines recommend either medical therapy or surgical treatment for TR, the misconception of TR as a benign disease along with the high mortality rates of surgical intervention led to undertreating this disease and commonly describing it as a "forgotten" valve. Recently, the development of transcatheter interventions for TR show promising potential for use in the clinical setting. There are currently few approved and numerous tested percutaneously delivered devices, which can be categorized, based on their mechanism of action, to either valve repair or valve replacement procedures. Both procedures were tested in clinical trials and show an echocardiographic reduction in TR sustained for at least 1 year after the procedure, as well as symptom relief and functional improvement of the patients. Device selection should be personalized, taking into consideration the anatomy of each valve and the available options at each heart center. Moreover, appropriate patient selection and timing of the procedure are also crucial for the success of the procedure. In this review, we analyze the clinical trials available for all devices currently approved or tested, aiming to provide a comprehensive summary of the most recent evidence in the field of transcatheter TR interventions.

Left ventricular mass versus pulse wave velocity as predictors of coronary artery disease in hypertensive patients: data from a 6-year-follow-up study.

In treated hypertensive patients, there is a substantial residual cardiovascular (CV) risk that cannot be assessed by the available prediction models. This risk can be associated with subclinical organ damage, such as increased left ventricular mass (LVM) and arterial stiffness. However, it remains unknown which of these two CV markers better predicts coronary artery disease (CAD). A prospective cohort study was used to answer the above question. The study sample consisted of 1033 patients with hypertension (mean age 55.6 years, 538 males) free of CAD at baseline, who were followed for a mean period of 6 years. At baseline, all subjects underwent a complete echocardiographic study and pulse wave velocity (PWV) measurement. Hypertensive individuals who developed CAD (2.8%) compared to those without CAD at follow-up, had a higher baseline LVM index (by 16.7 g/m2, p < 0.001), higher prevalence of left ventricular hypertrophy (LVH) (21% greater, p = 0.027) and greater prevalence of high PWV levels at baseline (21% greater, p = 0.019). Multivariate Cox regression analysis revealed that baseline age >65 years (HR = 2.067, p = 0.001), male gender (HR = 3.664, p = 0.001), baseline chronic kidney disease (HR = 2.020, p = 0.026), baseline diabetes mellitus (HR = 1.952, p = 0.015) and baseline LVH (HR = 2.124 p = 0.001) turned out to be independent predictors of CAD, whereas high PWV levels were not. LVH proved to be an independent prognosticator of CAD in contrast to arterial stiffness that was not related to CAD after accounting for established confounders. Therefore, LVM can reliably help physicians to identify high-risk hypertensives in whom an intensified therapeutic management is warranted.

Profile and management of hypertensive urgencies and emergencies in the emergency cardiology department of a tertiary hospital: a 12-month registry.

AIMS: Currently there are scarce epidemiological data regarding prevalence, clinical phenotype, and therapy of hypertensive urgencies (HU) and emergencies (HE). The aim of this article was to record the prevalence, clinical characteristics, and management of patients with HU and HE assessed in an emergency department (ED) of a tertiary hospital. METHODS AND RESULTS: The population consisted of patients presenting with HE and HU in the ED (acute increase in systolic blood pressure (BP) ≥ 180 mmHg and/or diastolic BP ≥120 mmHg with and without acute target organ damage, respectively). Of the 38 589 patients assessed in the ED during a 12-month period, 353 (0.91%) had HU and HE. There were 256 (72.5%) cases presented as HU and 97 (27.5%) as HE. Primary causes for both HU and HE were stress/anxiety (44.9%), increased salt intake (33.9%), and non-adherence to medication (16.2%). Patients with HU reported mainly dizziness/headache (46.8%) and chest pain (27.4%), whereas those with HE presented dyspnoea (67%), chest pain (30.2%), dizziness/headache (10.3%), and neurological disorders (8.2%). In HE, the underlying associated conditions were pulmonary oedema (58%), acute coronary syndrome (22.6%), and neurological disorders/stroke (7.2%). All HE cases were hospitalized and received intensive healthcare, including dialysis. CONCLUSION: This 1-year single-centre registry demonstrates a reasonable prevalence of HU and HE contributing to the high volume of visits to the ED. Stress, increased salt intake and non-adherence were main triggers of HE and HU. Dizziness and headache were the prevalent symptoms of HU patients while heart failure was the most common underlying disease in patients with HE.

Fatty liver index and hypertension-mediated organ damage in never-treated hypertensive patients without diabetes mellitus.

BACKGROUND: We investigated whether fatty liver index (FLI), a surrogate marker of nonalcoholic fatty liver disease (NAFLD), is associated with hypertension-mediated organ damage (HMOD) in never-treated hypertensive patients without diabetes mellitus. METHODS: We performed both clinic and ambulatory blood pressure (BP) measurements, and calculated the FLI for all participants. A FLI of no less than 60 indicates a high-risk of underlying NAFLD, whereas a FLI of less than 60 indicates lower risk. We evaluated left ventricular mass (LVM) by echocardiography, arterial stiffness by carotid--femoral pulse wave velocity (PWV), capillary rarefaction by nailfold capillaroscopy, as well as urinary albumin-to-creatinine ratio (ACR). HMOD was defined according to the categorical thresholds for each domain, except for capillary rarefaction in which case the categorization of patients was made by the median. RESULTS: We included 146 hypertensive patients (men, 43.8%; mean age, 56.6 ±â€Š10.8 years; BMI, 30.3 ±â€Š4.9 kg/m2; FLI, 57.2 ±â€Š27.7; office, systolic/diastolic, and 24-h BP, 153.5 ±â€Š15.8/94.7 ±â€Š9.8 mmHg, and 140.5 ±â€Š9.9/83.8 ±â€Š9 mmHg, respectively). Patients with FLI at least 60 (n = 76) were younger, with higher BMI and 24-h SBP, compared with patients with FLI less than 60 (n = 70). FLI was associated with HMOD after adjustment (LVM indexed to height, P = 0.004; PWV, P = 0.047; reduced capillary density, P = 0.001; and logACR, P = 0.003). High-risk FLI phenotype and FLI z scores increased the likelihood of any HMOD by 3.8 (95% confidence interval, 1.6-7.1) and 5.4 (95% confidence interval, 2.3-15.0) times, respectively. However, the increased number of HMOD domains has progressively stopped being determined by the FLI z scores (P = 0.65). CONCLUSION: High-risk FLI pattern was associated with various HMOD, and may re-classify never-treated hypertensive patients without diabetes mellitus into a higher cardiovascular risk level.

Isolated diastolic vs. systolic hypertension phenotypes and outcomes: prospective cohort of newly diagnosed individuals with hypertension.

AIMS: To evaluate whether different hypertension phenotypes, namely, isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH) and systolic/diastolic hypertension (SDH) have a differential outcome effect by clinic and ambulatory blood pressure (BP) measurements. METHODS: We prospectively evaluated in 569 never-treated patients with sustained hypertension (age 52.6 ±â€Š11.6 years; men 55%; clinic BP 150 ±â€Š15/95.5 ±â€Š10 mmHg, systolic/diastolic; 24-h ambulatory BP 128.9 ±â€Š12.6/80.6 ±â€Š9.7) the incidence of major cardiovascular (CV) events within 5 years, after adjustment for confounders, including the rate of BP control and the weighted follow-up BP. RESULTS: All participants received antihypertensive drug treatment (mean number of drugs 1.9 ±â€Š1.1; follow-up visits 4.6/patient). Average clinic BP achieved during follow-up was 136 ±â€Š12.6/83.9 ±â€Š9.4 mmHg, with 39% of participants having clinic BP less than 140/90 mmHg in at least 75% of their visits, and 24% in 25-75% of visits. Prevalence of hypertension phenotypes defined using BP differed from that using ambulatory BP, whereas integration of both BP measurements reclassified the initial phenotype to another in 18% of participants. Although, no differential outcome effect was observed between clinic IDH and SDH assessed using clinic or ambulatory BP measurements, clinic BP-based ISH was associated with a higher outcome incidence than the IDH and SDH phenotypes (hazard ratio 4.8, 95% confidence interval 1.4-17.0, P = 0.015). ISH diagnosed by integration of clinic and ambulatory BP, also increased the outcome (hazard ratio 4.0, 95% confidence interval 1.0-15.6, P = 0.046). CONCLUSION: In hypertensive patients at low/moderate CV risk, IDH and SDH phenotypes defined by clinic BP measurements, equally determined CV events but to a lower extent compared with ISH.
