Reviews in Cardiovascular Medicine

Noncommunicable chronic diseases, such as obesity, cardiovascular disease (CVD), and type 2 diabetes (T2D), pose significant health challenges globally. Important advances have been made in the understanding of the pathophysiologal mechanisms and treatment of noncommunicable diseases in recent years. Lack of physical activity is a primary contributor to many noncommunicable diseases including metabolic syndrome, T2D, CVD, and obesity. Certain diabetes medications and non-pharmaceutical interventions, such as physical activity and exercise, are shown to be effective in decreasing the CVD risks associated with heart disease, stroke, obesity, prediabetes, and T2D...

Chronic kidney disease (CKD) is associated with an increased risk for cardiovascular disease (CVD), major adverse CVD events, and cardiovascular mortality. Low levels of physical activity and reduced cardiorespiratory fitness further compound the health consequences in this patient population. Aerobic exercise alone and the combination of aerobic and resistance exercise have beneficial effects for improving aerobic capacity while resistance exercise alone improves strength and skeletal muscle health. Given the prevalence of CVD in CKD patients and limited treatment options targeting traditional and non-traditional CVD risk factors in this population, the incoroporation of physical activity and exercise into the care of CKD seems critical for improving patient outcomes...

BACKGROUND: The feasibility and long-term outcomes of the CrossBoss/Stingray for treating coronary chronic total occlusions (CTO) with distal diffuse disease landing zone remain unclear. METHODS: Consecutive CTO patients with distal diffuse lesions that underwent percutaneous coronary intervention by the CrossBoss/Stingray system at Xijing Hospital from April 2016 to October 2020, were included. Patients were analyzed by two groups according to the extent of stenosis in the distal landing zone: 50%-70% stenosis (moderate stenosis group) and >70% stenosis (severe stenosis group)...

BACKGROUND: Catheter ablation is an effective treatment for atrial fibrillation (AF), primarily performed in patients who fail antiarrhythmic drugs. Whether early catheter ablation, as first-line therapy, is associated with improved clinical outcomes remains unclear. METHODS: Electronic databases (PubMed, Scopus, Embase) were searched until March 28th, 2021. Randomized controlled trials (RCTs) compared catheter ablation vs antiarrhythmic drug therapy as first-line therapy were included...

A wide range of comorbidities play a pivotal role in worsening outcomes and increasing mortality risk in patients with heart failure (HF). Among them, renal dysfunction has been recognized as a highly prevalent prognostic variable, with a strong impact on prognosis, length of hospital stay and need for intensive care. In this context, recent evidence has pointed out the relevance of both systemic hypoperfusion and venous congestion on the imbalance of renal function as well as on the conditioning the pathophysiological crosstalk between heart and kidneys through a wide range of haemodynamic and biochemical pathways...

BACKGROUND: Elevated left ventricular mass index contributes to morbidity and mortality induced by heart failure and M2 macrophages play a critical role in left ventricular remodeling. Here, our aim was to investigate the roles of M2 macrophage-related genes in heart failure. METHODS: GSE10161 was downloaded and the abundance of immune cells were estimated utilizing the CIBERSORT algorithm. Using the limma test and correlation analysis, differentially expressed plasm B cells and M2 macrophages-related genes (DEBRGs and DEMRGs) were documented...

Restrictive cardiomyopathy (RCM), a potentially devastating heart muscle disorder, is characterized by diastolic dysfunction due to abnormal muscle relaxation and myocardial stiffness resulting in restrictive filling of the ventricles. Diastolic dysfunction is often accompanied by left atrial or bi-atrial enlargement and normal ventricular size and systolic function. RCM is the rarest form of cardiomyopathy, accounting for 2-5% of pediatric cardiomyopathy cases, however, survival rates have been reported to be 82%, 80%, and 68% at 1-, 2-, and 5-years after diagnosis, respectively...

Cardiac simulation has moved from early life-saving pacemakers meant only to prevent asystole to current devices capable of physiologic stimulation for the treatment of heart rhythm and heart failure, that are also intended for remote patient and disease-progression monitoring. The actual vision of contemporary pacing aims to correct the electrophysiologic roots of mechanical inefficiency regardless of underlying structural heart diseases. The awareness of the residual cardiac dyssynchrony related to customary cardiac pacing has changed the concept of what truly represents "physiologic pacing"...

Type 2 Diabetes Mellitus (T2DM) is associated with an elevated incidence of cardiovascular and renal diseases, responsible for mortality rates significantly higher than in the general population. The management of both cardiovascular risk and progression of kidney disease thus seem crucial in the treatment of the diabetic patient. The availability of new classes of drugs which positively affect both cardiovascular and renal risk, regardless of the glycemic control, represents a revolution in the treatment of T2DM and shifts the attention from the intensive glycemic control to a holistic management of the diabetic patient...

Chronic kidney disease (CKD) shows a high prevalence and is characterized by progressive and irreversible loss of renal function. It is also associated with a high risk of cardiovascular disease. The CKD population often suffers from atrial fibrillation (AF), which is associated with cardiovascular and all-cause mortality. There is a pernicious bidirectional relationship between CKD and AF: renal dysfunction can help promote AF initiation and maintenance, while unmanageable AF often accelerates kidney function deterioration...

BACKGROUND: Endovascular therapeutic hypothermia (ETH) reduces the damage by ischemia/reperfusion cell syndrome in cardiac arrest and has been studied as an adjuvant therapy to percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI). New available advanced technology allows cooling much faster, but there is paucity of resources for training to avoid delays in door-to-balloon time (DTB) due to ETH and subsequently coronary reperfusion, which would derail the procedure...

Outflow tract (OT) premature ventricular complexes (PVCs) are being recognized as a common and often troubling, clinical electrocardiographic finding. The OT areas consist of the Right Ventricular Outflow Tract (RVOT), the Left Ventricular Outflow Tract (LVOT), the Aortomitral Continuity (AMC), the aortic cusps and the Left Ventricular (LV) summit. By definition, all OT PVCs will exhibit an inferior QRS axis, defined as positive net forces in leads II, III and aVF. Activation mapping using the contemporary 3D mapping systems followed by pace mapping is the cornerstone strategy of every ablation procedure in these patients...

The potential modifiable factors for remote ischemic conditioning (RIC) in reducing contrast-associated acute kidney injury (CA-AKI) in patients with acute myocardial infarction (AMI) have not been investigated. The aim of this meta-regression was to address these issues.We searched Pubmed, Embase and the Cochrane Library database for published randomized controlled trials (RCTs) with registration number CRD42020155532. Nine RCTs comprising of 1540 subjects were included in our meta-analysis. Compared with control group, RIC was associated with reduced incidence of CA-AKI [(9 studies, 1540 subjects, relative risk (RR) 0...

Surgical ablation is a well-established therapy for patients with atrial fibrillation (AF) undergoing cardiac surgery. However, it is not clear if this translates to an improvement in patient important outcomes such as mortality, stroke, and quality of life (QoL). Electronic searches were performed of Ovid Medline and PubMed from their inception to October 2021. Eligible literature included comparative studies with patient undergoing surgical ablative treatment for AF concomitant to any cardiac surgery procedure and patients without specific AF treatment...

BACKGROUND: A potential relationship between oral health and cardiovascular diseases has been proposed. However, uncertainty remains as to whether there is sufficient data to support this association. This review aims to appraise the relationship between apical periodontitis and cardiovascular disease based on data from observational studies. METHODS: The databases Medline (via PubMed) and EMBASE (via Scopus) were searched up to August 2020 for observational studies (case-control, cross-sectional, and cohort) assessing the association of apical periodontitis with cardiovascular disease among adults...

BACKGROUND: The management of type II endoleaks (T2ELs) remains controversial in current literature. Hence, this study aimed to explore the natural history of isolated type II endoleak after endovascular aneurysm repair (EVAR) and its influence on long-term outcomes based on a 10-year follow-up at a tertiary medical center. METHODS: From January 2011 to April 2021, consecutive patients who underwent elective EVAR were reviewed. The demographics, clinical characteristics, treatment details, imaging information, in the event of T2ELs, and outcomes were extracted...

BACKGROUND: There is controversy over whether non-vitamin K antagonist oral anticoagulants (NOACs) use increase the risk of hepatic impairment in patients with non-valvular atrial fibrillation (NVAF). We conducted a comprehensive assessment using multi-source medical data. METHODS: We first performed a systematic search of the PubMed, Embase, and Cochrane Library databases (through 11 August 2021) for randomised controlled trials (RCTs) and real-world studies (RWSs) that reported hepatic impairment events in patients with NVAF administered NOACs or vitamin K antagonists (VKAs) therapy...

Toll-like receptors (TLRs) and interleukin-1 receptor (IL-1R) directly interact with intracellular interleukin receptor associated kinase (IRAK) family members to initialize innate immune and inflammatory responses following activation by pathogen-associated or host-derived elements. Although four IRAK family members [IRAK1, 2, 3 ( i.e., IRAK-M), and 4] are involved in TLR and IL-1R signaling pathways, IL-1R > IRAK1 signaling appears to be the most studied pathway, with sufficient evidence to support its central role linking the innate immune response to the pathogenesis of various diseases, including cancers, metabolic disorders, and non-infectious immune disorders...

Mitral valve prolapse (MVP) has a prevalence of 2-3% among the population. It involves a heterogeneous group of patients with different expressions and according to the phenotype can be further divided into fibroelastic deficiency, which is mainly considered as a degeneration due to aging, and myxomatous disease, frequently associated with familiar clusters. Thus, MVP can be present in syndromic, when part of a well-defined syndrome, and non-syndromic forms. The latter occurs more often. To the second belong both familiar and isolated or sporadic forms...
