RESUMO
Acute heart failure (HF) presents a significant mortality burden, necessitating continuous therapeutic advancements. Temporary mechanical circulatory support (MCS) is crucial in managing cardiogenic shock (CS) secondary to acute HF, serving as a bridge to recovery or durable support. Currently, MCS options include the Intra-Aortic Balloon Pump (IABP), TandemHeart (TH), Impella, and Veno-Arterial Extracorporeal Membrane Oxygenation (VA-ECMO), each offering unique benefits and risks tailored to patient-specific factors and clinical scenarios. This review examines the clinical implications of recent advancements in temporary MCS, identifies knowledge gaps, and explores promising avenues for future research and clinical application. Understanding each device's unique attributes is crucial for their efficient implementation in various clinical scenarios, ultimately advancing towards intelligent, personalized support strategies.
RESUMO
Background: Real-world data show limited utilization of direct oral anticoagulants (DOACs) in obese patients (body mass index [BMI] ≥ 30 kg/m2) due to concerns regarding their efficacy and safety in this demographic. Aim: This review aimed to consolidate current evidence on the efficacy and safety of DOACs versus warfarin in obese patients with non-valvular atrial fibrillation (AF) or venous thromboembolism (VTE). The primary efficacy outcome assessed a composite of all-cause mortality, stroke, systemic embolism (SE), and myocardial infarction (MI). Methods: A systematic search was conducted in MEDLINE, SCOPUS, and Cochrane databases from inception to December 28, 2023. Data were synthesized using random-effects meta-analysis. Results: A total of 35 studies involving 434,320 participants were analyzed. DOAC use was associated with a significant reduction in the risk of the composite outcome (RR = 0.80, 95% CI [0.65, 0.98], I2 = 95%), hemorrhagic stroke (RR = 0.58, 95% CI [0.38, 0.88], I2 = 92%), major bleeding (RR = 0.76, 95% CI [0.63, 0.92], I2 = 94%), gastrointestinal bleeding (RR = 0.59, 95% CI [0.49, 0.72], I2 = 88%), and intracranial bleeding (RR = 0.45, 95% CI [0.34, 0.60], I2 = 44%) compared to warfarin. A non-significant benefit of DOACs was observed for all-cause mortality, MI, the composite of stroke or SE, ischemic stroke, SE, VTE, and minor bleeding compared to warfarin. Subgroup analysis indicated no significant effect modification based on the indication for anticoagulation or study design. Conclusions: DOACs demonstrated a favorable efficacy and safety profile in obese individuals compared to warfarin.
RESUMO
Heart failure (HF) poses a significant world health challenge due to the increase in the aging population and advancements in cardiac care. In the pathophysiology of HF, the inflammasome has been correlated with the development, progression, and complications of HF disease. Discovering biomarkers linked to inflammasomes enhances understanding of HF diagnosis and prognosis. Directing inflammasome signaling emerges as an innovative therapeutic strategy for managing HF. The present review aims to delve into this inflammatory cascade, understanding its role in the development of HF, its potential role as biomarker, as well as the prospects of modulating inflammasomes as a therapeutic approach for HF.

There are scarce data on the comparative prognosis between patients with hypertensive emergencies (HE), urgencies (HU), and those without HU or HE (HP). Our study aimed to compare cardiovascular (CV) outcomes of HE, HU, and HP during a 12-month follow-up period. The population consisted of 353 consecutive patients presenting with HE or HU in a third-care emergency department and subsequently referred to our hypertension center for follow-up. After both groups completed scheduled follow-up visits, patients with HU were matched one-to-one by age, sex, and hypertension history with HP who attended our hypertension center during the same period. Primary outcomes were 1) a recurrent hypertensive HU or HE event and 2) non-fatal CV events (coronary heart disease, stroke, heart failure, or CV interventions), while secondary outcomes were 1) all-cause death, 2) CV death, 3) non-CV death, and 4) any-cause hospitalization. Events were prospectively registered for all three groups. During the study period, 81 patients were excluded for not completing follow-up. Among eligible patients(HE = 94; HU = 178), a total of 90 hospitalizations and 14 deaths were recorded; HE registered greater CV morbidity when compared with HU (29 vs. 9, HR 3.43, 95 % CI 1.7-6.9, p = 0.001), and increased CV mortality (8 vs. 1, HR 13.2, 95 % CI 1.57-110.8, p = 0.017). When opposing HU to HP, events did not differ substantially. Cox regression models were adjusted for age, sex, CV and chronic kidney disease, diabetes mellitus, and smoking. During 1-year follow-up, the prognosis of HU was better than HE but not different compared to HP. These results highlight the need for improved care of HU and HE.

BACKGROUND: Current guidelines recommend a rhythm control strategy in patients with symptomatic atrial fibrillation (AF) while catheter ablation has been shown to be a safer and more efficacious approach than antiarrhythmic medications. METHODS: HECMOS was a nationwide snapshot survey of cardiorenal morbidity in hospitalized cardiology patients. In this sub-study, we included 276 cases who had a history of AF, particularly on the rhythm strategy, and catheter ablation procedures had been performed before the index admission. RESULTS: Among 276 AF patients (mean age: 76.4⯱â¯11.5â¯years, 58â¯% male), 60.9â¯% (Nâ¯=â¯168) had persistent AF and 39.1â¯% (Nâ¯=â¯108) had paroxysmal AF. Heart failure was the main cause of admission in 54.3â¯% (Nâ¯=â¯145) of the patients, while 14.1â¯% (Nâ¯=â¯39) were admitted due to paroxysmal AF, 7.3â¯% (Nâ¯=â¯20) due to bradyarrhythmic reasons, and 6.5â¯% (Nâ¯=â¯18) suffered from acute coronary syndrome. Most importantly, heart failure with reduced ejection fraction was present in 76 (27â¯%) patients. Only 10 patients out of the total (3â¯%, mean age 59.7â¯years) had undergone AF ablation while electrical cardioversion had been attempted in 37 (13.4â¯%) patients. Interestingly, in this AF population with heart failure, 3.6â¯% (Nâ¯=â¯10) had a defibrillator implanted (4 single-chamber), and only 1.5â¯% (Nâ¯=â¯4) had a cardiac resynchronization therapy defibrillator (CRT-D). CONCLUSION: High prevalence of persistent AF was detected in hospitalized patients, with heart failure being the leading cause of admission and main co-morbidity. Rhythm control strategies are notably underused, along with CRT-D implantation in patients with AF and heart failure.

Sleep disordered breathing (SDB), mostly constituting of obstructive and central sleep apnea (OSA and CSA, respectively), is highly prevalent in the general population, and even more among patients with cardiovascular disease, heart failure (HF) and valvular heart disease, such as mitral regurgitation (MR). The coexistence of HF, MR and SDB is associated with worse cardiovascular outcomes and increased morbidity and mortality. Pulmonary congestion, as a result of MR, can exaggerate and worsen the clinical status and symptoms of SDB, while OSA and CSA, through various mechanisms that impair left ventricular dynamics, can promote left ventricular remodelling, mitral annulus dilatation and consequently MR. Regarding treatment, positive airway pressure devices used to ameliorate symptoms in SDB also seem to result in a reduction of MR severity, MR jet fraction and an improvement of left ventricular ejection fraction. However, surgical and transcatheter interventions for MR, and especially transcatheter edge to edge mitral valve repair (TEER), seem to also have a positive effect on SDB, by reducing OSA and CSA-related severity indexes and improving symptom control. The purpose of this review is to provide a comprehensive analysis of the common pathophysiology between SDB and MR, as well as to discuss the available evidence regarding the effect of SDB treatment on MR and the effect of mitral valve surgery or transcatheter repair on both OSA and CSA.

Acute coronary syndromes (ACSs) encompass a spectrum of life-threatening cardiovascular conditions, including unstable angina (UA) and myocardial infarction. While significant progress has been made in the understanding and management of ACS over the years, it has become increasingly evident that sex-based differences play a pivotal role in the pathophysiology, presentation, and outcomes of these conditions. Despite this recognition, the majority of clinical research in the field has historically focused on male populations, leading to a significant knowledge gap in understanding the unique aspects of ACS in women. This review article aims to comprehensively explore and synthesize the current body of literature concerning the sex-specific characteristics of ACS, shedding light on the epidemiology, risk factors, clinical presentation, diagnostic challenges, treatment strategies, and prognosis in women. By elucidating the distinct aspects of ACS in women, this review intends to foster greater awareness and improved clinical management, ultimately contributing to enhanced cardiovascular care for female patients.
RESUMO
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.

AIMS: The beneficial cardiovascular effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors irrespective of the presence of diabetes mellitus are nowadays well established and they already constitute a significant pillar for the management of heart failure, irrespective of the ejection fraction. The exact underlying mechanisms accountable for these effects, however, remain largely unknown. The direct effect on endothelial function and microcirculation is one of the most well studied. The broad range of studies presented in this review aims to link all available data from the bench to bedside and highlight the existing gaps as well as the future directions in the investigations concerning the effects of SGLT2 inhibitors on the endothelium and the microcirculation. METHODS AND RESULTS: An extensive search has been conducted using the MEDLINE/PubMed database in order to identify the relevant studies. Preclinical data suggest that SGLT2 inhibitors directly affect endothelial function independently of glucose and specifically via several interplaying molecular pathways, resulting in improved vasodilation, increased NO production, enhanced mitochondrial homeostasis, endothelial cell viability, and angiogenesis as well as attenuation of oxidative stress and inflammation. Clinical data systematically confirm this beneficial effect on the endothelium, whereas the evidence concerning the effect on the microcirculation is conflicting. CONCLUSION: Preclinical and clinical studies indicate that SGLT2 inhibitors attenuate endothelial and microvascular dysfunction via a combination of mechanisms, which play a role in their beneficial cardiovascular effect.

PURPOSE: Cardiovascular disease is commonly accompanied by renal dysfunction. Multimorbidity in hospitalized patients impacts unfavorably on prognosis and hospital stay. We aimed to illustrate the contemporary burden of cardiorenal morbidity across inpatient cardiology care in Greece. METHODS: The Hellenic Cardiorenal Morbidity Snapshot (HECMOS) used an electronic platform to collect demographic and clinically relevant information about all patients hospitalized on March 3, 2022, in Greece. The participating institutions covered all levels of inpatient cardiology care and most of the country's territories to collect a real-world, nation representative sample. RESULTS: A total of 923 patients (men 68.4%, median age 73 ± 14.8 years) were admitted to 55 different cardiology departments. 57.7% of the participants were aged >70 years. Hypertension was highly prevalent and present in 66% of the cases. History of chronic HF, diabetes mellitus, atrial fibrillation, and chronic kidney disease was present in 38%, 31.8%, 30%, and 26%, respectively. Furthermore, 64.1% of the sample exhibited at least one of these 4 entities. Accordingly, a combination of ≥2 of these morbid conditions was recorded in 38.7%, of ≥3 in 18.2%, whereas 4.3% of the sample combined all 4 in their medical history. The most common combination was the coexistence of heart failure-atrial fibrillation accounting for 20.6% of the sample. Nine of 10 nonelectively admitted patients were hospitalized due to acute HF (39.9%), acute coronary syndrome (33.5%), or tachyarrhythmias (13.2%). CONCLUSION: HECMOS participants carried a remarkable burden of cardio-reno-metabolic disease. HF in conjunction with atrial fibrillation was found to be the most prevalent combination among the studied cardiorenal nexus of morbidities in the whole study population.

The mechanisms leading to the development of heart failure (HF) in diabetes mellitus (DM) patients are multifactorial. Assessing the risk of HF development in patients with DM is valuable not only for the identification of a high-risk subgroup, but also equally important for defining low-risk subpopulations. Nowadays, DM and HF have been recognized as sharing similar metabolic pathways. Moreover, the clinical manifestation of HF can be independent of LVEF classification. Consequently, approaching HF should be through structural, hemodynamic and functional evaluation. Thus, both imaging parameters and biomarkers are important tools for the recognition of diabetic patients at risk of HF manifestation and HF phenotypes, and arrhythmogenic risk, and eventually for prognosis, aiming to improve patients' outcomes utilizing drugs and non-pharmaceutical cardioprotective tools such as diet modification.

Current evidence on the prognosis of patients with a hypertensive crisis and predisposing factors is limited. We registered the clinical phenotype of patients with HC admitted to the emergency department, while those with a hypertensive emergency (HE) were hospitalized. One-year outcomes, i.e., composite of death or cardiovascular hospitalizations, were determined in patients with HE after hospital discharge. Out of 38,589 patients assessed in the emergency department, 256 hypertensive urgencies and 97 HE was registered. After stratification of the HE by sex, 48 men and 46 women completed the one-year follow-up. Men had more events than women (27 vs. 13, Ηazard Ratio 2.2, 95% Confidence Interval 1.03-4.7, p = 0.042) after adjustment for age, cardiovascular or chronic kidney disease, and diabetes mellitus. Our study raises the hypothesis that the male sex is an independent risk factor for cardiovascular outcomes in HE patients. CV Cardiovascular, BP blood pressure. The diagram presents the groups of comparison, men versus women in hypertensive emergencies that completed the 1-year follow-up for outcomes, in terms of hospitalizations or deaths.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic provoked unprecedented disturbance in hypertension care, while alarming concerns arose about its long-term consequences. We investigated the trends of emergency visits and admissions regarding uncontrolled hypertension in order to assess the impact of COVID-19 spread on population behavior towards hypertension urgencies during its first wave. Material and methods: Data from daily unscheduled visits and admission counts in the Cardiology sector were collected from the Emergency Department database of a tertiary General Hospital in Athens, Greece for the period January 15th to July 15th 2020. These data were compared with those from the previous year. Cases of patients who presented with hypertensive urgency or who were admitted due to uncontrolled hypertension were separately analyzed. Results: A total of 7,373 patient records were analyzed. Hypertension urgency cases demonstrated a U-shaped distribution in 2020, showing a declining trend during the rapid virus spread, an image that was reversed after the transmission rate's decline. COVID-19 incidence in Greece was inversely associated with uncontrolled hypertension admissions during its declining phase (r = -0.64, p = 0.009), whereas total attendance exhibited a similar correlation during the first and the following months of the pandemic (r = 0.677, p = 0.031, r = -0.789, p = 0.001). Uncontrolled hypertension rate on admission was positively related to the national incidence of COVID-19 cases during the first months of 2020 (r = 0.82, p = 0.045). Conclusions: Hypertensive urgency-related visits followed a U-shape distribution during the pandemic's first wave with the attendance nadir coinciding with the virus spread peak. This is a complex phenomenon, closely related to increased levels of public stress, disruptions in health care services and to a lesser extent to the imposed restrictions in transportation. The initial relative increase in uncontrolled hypertension-related admissions rate, combined with the later increase of hypertensive urgencies may be indicative of blood pressure deregulation among the studied population, which is multifactorial and potentially detrimental.
RESUMO
Acute tobacco cigarette (TC) smoking increases blood pressure and sympathetic nerve activity, whereas there are scarce data on the impact of electronic cigarette (EC) smoking. We assessed the acute effects of TC, EC and sham smoking on blood pressure, heart rate and sympathetic nervous system. Methods: We studied 12 normotensive male habitual smokers (mean age 33 years) free of cardiovascular disease. The study design was randomized and sham controlled with three experimental sessions (sham smoking, TC smoking and EC smoking). After baseline measurements at rest, the subjects were then asked to smoke (puffing habits left uncontrolled) two TC cigarettes containing 1.1 mg nicotine, EC smoking or simulated smoking with a drinking straw with a filter (sham smoking), in line with previous methodology. Results: EC smoking at 5 and 30 min compared to baseline was accompanied by the augmentation of mean arterial pressure (MAP) and heart rate (p < 0.001 for all). The muscle sympathetic nerve activity (MSNA) decrease was significant during both TC and EC sessions (p < 0.001 for both comparisons) and was similar between them (−25.1% ± 9.8% vs. −34.4% ± 8.3%, respectively, p = 0.018). Both MSNA decreases were significantly higher (p < 0.001 for both comparisons) than that elicited by sham smoking (−4.4% ± 4.8%). Skin sympathetic nerve activity increase was significant in both TC and EC groups (p < 0.001 for both comparisons) and similar between them (73.4% ± 17.9% and 71.9% ± 7%, respectively, p = 0.829). Conclusions: The unfavorable responses of sympathetic and arterial pressure to EC smoking are similar to those elicited by TC in healthy habitual smokers.

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.

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.

BACKGROUND: High blood pressure (BP) is a leading risk factor for coronary artery disease and other major cardiovascular events. OBJECTIVE: Blood pressure variability (BPV), ambulatory arterial stiffness index (AASI) and ankle- brachial index (ABI) have been proposed as indices that can improve risk stratification for an adverse cardiac outcome. However, their utility in the setting of acute coronary syndromes (ACS) is unclear. METHODS: The ACS-BP study is a single-centre observational cohort study designed to investigate the prognostic role of haemodynamic load and arterial stiffness indices for cardio-renal outcomes in patients with acute myocardial infarction (AMI). All consecutive patients admitted with a diagnosis of acute AMI with or without ST segment elevation were screened for inclusion in the study. The management of AMI will follow current guidelines. RESULTS AND DISCUSSION: Data from baseline clinical and laboratory parameters during their hospitalization were collected. The haemodynamic load of each patient was determined by clinical BP values as well as 24-h ambulatory BP monitoring. The AASI was calculated from the raw 24-h BP data and ABI was measured after the third day of hospitalization using a certified device. Patients were followed-up for 12 months in order to collect data for hard cardiovascular and renal endpoints. CONCLUSION: The study results should clarify the role of these non-invasive tools in secondary risk stratification of such patients.
