Flexible Bronchoscopy Combined With an Airway Maneuver for Foreign Material Removal Under Invasive Mechanical Ventilation.

We present a case of a patient who had aspirated a massive amount of food, leading to cardiac arrest, and had to be intubated because of severe hypoxemia. The hypoxemia persisted, regardless of the recruitment maneuvers, performance of flexible bronchoscopy, and suctioning through the ventilating tube, because we were unable to reach the left main bronchus (LMB), where the greatest amount was concentrated. However, we managed to overcome this problem by using a prototype handling technique to catheterize the LMB directly with the usage of the flexible bronchoscope.

Exercise Effects on Left Ventricular Remodeling in Patients with Cardiometabolic Risk Factors.

Left ventricular (LV) remodeling is a dynamic process, which is characterized by changes in ventricular size, shape, and wall thickness, thus altering myocardial geometry and function, and is considered as a negative prognostic factor in patients with heart failure (HF). Hypertension, type 2 diabetes (T2D), and obesity are strongly correlated with the development and the progression of LV remodeling, LV hypertrophy, and LV systolic and/or diastolic dysfunction. Indeed, the beneficial impact of exercise training on primary and secondary prevention of cardiovascular disease (CVD) has been well-established.

Risk Factors for Weaning Failure in COVID-19 Patients.

Background: Data on risk factors associated with mechanical ventilation (MV) weaning failure among SARS-CoV2 ARDS patients is limited. We aimed to determine clinical characteristics associated with weaning outcome in SARS-CoV2 ARDS patients under MV.

Objectives: To determine potential risk factors for weaning outcome in patients with SARS-CoV2 ARDS.

Regional expert opinion: Management of heart failure with preserved ejection fraction in the Middle East, North Africa and Turkey.

Although epidemiological data on heart failure (HF) with preserved ejection fraction (HFpEF) are scarce in the Middle East, North Africa and Turkey (MENAT) region, Lancet Global Burden of Disease estimated the prevalence of HF in the MENAT region in 2019 to be 0.78%, versus 0.71% globally.

The Role of Right Ventriculo-Arterial Coupling in Symptoms Presentation of Patients with Hypertrophic Cardiomyopathy.

Background: Hypertrophic cardiomyopathy (HCM) is the most common inherited cardiomyopathy. The hallmark of HCM is myocardial fibrosis which contributes to heart failure, arrhythmias, and sudden cardiac death (SCD).

Objective: To identify the factors implicated in heart failure symptoms and functional capacity of patients with HCM.

Regional variations in patient selection and procedural characteristics for cryoballoon ablation of atrial fibrillation in the cryo global registry.

Background: Cryoballoon ablation is a well-established anatomical approach for pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF). Although widely adopted, regional variations in standards of care have not been well characterized.

Methods: Patients with AF were enrolled in the Cryo Global Registry (NCT02752737) from May 2016 to Sept 2021 at 128 sites in 37 countries and treated with cryoballoon ablation according to local clinical practice.

Interleukin-6 Signaling in Atherosclerosis: From Molecular Mechanisms To Clinical Outcomes.

Interleukin-6 (IL-6) is a cytokine centrally involved in several immune responses and it has been recognized as a driver of enhanced atherothrombotic risk. Immunity and inflammation are intrinsically involved in atherosclerosis progression. This generated 'inflammation hypothesis', which is now validated in large-scale clinical trials.

Prolonged impact of anti-cancer therapy on endothelial function and arterial stiffness in breast cancer patients.

Background: Cardiotoxicity restricts anthracycline and trastuzumab treatment of Human Epidermal Growth Factor Receptor 2 positive early breast cancer. Endothelial dysfunction and arteriosclerosis are significant cardiovascular risk factors.

Objectives: We studied the effect of anthracycline-based chemotherapy, with or without trastuzumab, on endothelium and arteriosclerosis in patients with breast cancer.

Outcomes Following Radiofrequency Renal Denervation According to Antihypertensive Medications: Subgroup Analysis of the Global SYMPLICITY Registry DEFINE.

Background: The Global SYMPLICITY Registry DEFINE (Denervation Findings in Real World) investigates radiofrequency renal denervation (RDN) in a broad range of patients with hypertension. We evaluated whether the number or type of antihypertensive medications were associated with increased long-term blood pressure (BP) reductions and cardiovascular outcomes following radiofrequency RDN.

Methods: Patients underwent radiofrequency RDN and were categorized by baseline number (0-3 and ≥4) and different combinations of medication classes.

Efficacy, Safety and Feasibility of Superior Vena Cava Isolation in Patients Undergoing Atrial Fibrillation Catheter Ablation: An Up-to-Date Review.

Pulmonary vein isolation (PVI) is the cornerstone in atrial fibrillation (AF) ablation; yet, the role of arrhythmogenic superior vena cava (SVC) is increasingly recognized and different ablation strategies have been employed in this context. SVC can act as a trigger or perpetuator of AF, and its significance might be more pronounced in patients undergoing repeated ablation. Several cohorts have examined efficacy, safety and feasibility of SVC isolation (SVCI) among AF patients.

Left atrial appendage morphofunctional indices could be predictive of arrhythmia recurrence post-atrial fibrillation ablation: a meta-analysis.

Background: Left atrium changes are implicated in atrial fibrillation (AF) substrate and are predictive of AF outcomes. Left atrial appendage (LAA) is an integral component of left atrial structure and could be affected by atrial cardiomyopathy. We aimed to elucidate the association between LAA indices and late arrhythmia recurrence after atrial fibrillation catheter ablation (AFCA).

Lipoprotein(a) and calcific aortic valve disease initiation and progression: a systematic review and meta-analysis.

Although evidence indicates the association of lipoprotein(a) [Lp(a)] with atherosclerosis, the link with calcific aortic valve disease (CAVD) is unclear. This systematic review and meta-analysis explores the connection between Lp(a) and aortic valve calcification and stenosis (AVS). We included all relevant studies, indexed in eight databases, up to February 2023.

The Role of Shear Stress in Coronary Artery Disease.

Coronary artery disease is the leading cause of morbidity and mortality worldwide, especially in developed countries, with an increasing incidence in developing countries. Despite the advances in cardiology, there are yet many unanswered questions about the natural history of coronary atherosclerosis. However, it has not been fully explained why some coronary artery plaques remain quiescent over time, whereas others evolve to a high-risk, "vulnerable" plaque with a predisposition to destabilize and induce a cardiac event.

The Role of Rehabilitation in Arterial Function Properties of Convalescent COVID-19 Patients.

Coronavirus disease (COVID-19) is a respiratory disease, although arterial function involvement has been documented. We assess the impact of a post-acute COVID-19 rehabilitation program on endothelium-dependent vasodilation and arterial wall properties. We enrolled 60 convalescent patients from COVID-19 and one-month post-acute disease, who were randomized at a 1:1 ratio in a 3-month cardiopulmonary rehabilitation program (study group) or not (control group).

Advances in the Management of Heart Failure with Reduced Ejection Fraction; The Role of SGLT2is, ARNI, Myotropes, Vericiguat, and Anti-inflammatory Agents: A Mini-review.

Heart failure with reduced ejection fraction (HFrEF) has been associated with poor prognosis, reduced quality of life, and increased healthcare expenditure. Despite tremendous advances in HFrEF management, reduced survival and a high rate of hospitalization remain unsolved issues. Furthermore, HFrEF morbidity and economic burden are estimated to increase in the following years; hence, new therapies are constantly emerging.

Molecular Mechanisms and Therapeutic Implications of Endothelial Dysfunction in Patients with Heart Failure.

Heart failure is a complex medical syndrome that is attributed to a number of risk factors; nevertheless, its clinical presentation is quite similar among the different etiologies. Heart failure displays a rapidly increasing prevalence due to the aging of the population and the success of medical treatment and devices. The pathophysiology of heart failure comprises several mechanisms, such as activation of neurohormonal systems, oxidative stress, dysfunctional calcium handling, impaired energy utilization, mitochondrial dysfunction, and inflammation, which are also implicated in the development of endothelial dysfunction.

Lipoprotein(a) in Atherosclerotic Diseases: From Pathophysiology to Diagnosis and Treatment.

Lipoprotein(a) (Lp(a)) is a low-density lipoprotein (LDL) cholesterol-like particle bound to apolipoprotein(a). Increased Lp(a) levels are an independent, heritable causal risk factor for atherosclerotic cardiovascular disease (ASCVD) as they are largely determined by variations in the Lp(a) gene (LPA) locus encoding apo(a). Lp(a) is the preferential lipoprotein carrier for oxidized phospholipids (OxPL), and its role adversely affects vascular inflammation, atherosclerotic lesions, endothelial function and thrombogenicity, which pathophysiologically leads to cardiovascular (CV) events.

Life-Threatening Hypotension in a Brain-Injured, Multi-Trauma Patient With Unilateral Adrenal Gland Damage: How a Single Hydrocortisone Dose Revealed Relative Corticosteroid Insufficiency.

We report a case of a multi-trauma, brain-injured young patient with unilateral adrenal gland injury presenting with refractory shock. Acute adrenal insufficiency was revealed after an abrupt hemodynamic response to a corticosteroid; the resistant shock was quickly resolved with IV hydrocortisone. Although available data do not support the use of empiric steroids in trauma patients (with or without brain injury), this case demonstrates that adrenal insufficiency must be considered in the differential diagnosis when shock exists; adrenal gland injury, even unilateral, may play an additional factor.

Adhesion Molecules as Prognostic Biomarkers in Coronary Artery Disease.

Atherosclerosis is a progressive disease, culminating in the production of atherosclerotic plaques in arteries through intricate pathophysiological processes. The progression of this disorder is based on the effect of triggering factors -mainly hyperlipidemia, diabetes mellitus, arterial hypertension, and smoking- on the endothelium. Coronary artery disease (CAD) is an atherosclerotic disease with a higher prevalence among individuals.

Lipoprotein (a) Levels and Abdominal Aortic Aneurysm. A Systematic Review and Meta-analysis.

Background: Several studies have linked high Lipoprotein (a) (Lp(a)) concentrations to cardiovascular events, including the formation of Abdominal Aortic Aneurysms (AAA). We review and meta-analyze existing evidence on the association of Lp(a) levels with AAA.

Methods: Studies evaluating the link of Lp(a) with AAA, up to December 27th 2021, were identified by a systematic search of PubMed, SCOPUS, and Web of Science databases.
