Mitochondria-Targeted Drug in Cardiovascular Disease
Cardiovascular disease (CVD) represents a major threat for human health. The available preventive and treatment interventions are insufficient to revert the underlying pathological processes, which underscores the urgency of alternative approaches. Mitochondria dysfunction plays a key role in the etiopathogenesis of CVD and is regarded as an intriguing target for the development of innovative therapies. Oxidative stress, mitochondrial permeability transition pore opening, and excessive fission are major noxious pathways amenable to drug therapy. Thanks to the advancements of nanotechnology research, several mitochondria-targeted drug delivery systems (DDS) have been optimized with improved pharmacokinetic and biocompatibility, and lower toxicity and antigenicity for application in the cardiovascular field.

High-Density Lipoprotein
High-density lipoprotein (HDL), the smallest and most dense lipoprotein, is composed of a central hydrophobic non-polar lipid core, consisting of primarily triacylglycerols and cholesterol esters.

Anatomical-MRI Correlations in Hypertrophic Cardiomyopathy Adults and Children
Hypertrophic Cardiomyopathy (HCM) is the most frequent hereditary cardiovascular disease and the leading cause of sudden cardiac death in young individuals. Advancements in CMR imaging have allowed for earlier identification and more accurate prognosis of HCM. CMR has been validated as a technique with high sensitivity and specificity, very few contraindications, a low risk of side effects, and is overall a good tool to be employed in the management of HCM patients.

Patent Foramen Ovale
A patent foramen ovale (PFO) is a commonly discovered potential opening between the right atrium (RA) and left atrium (LA) on routine echocardiographic surveillance in an otherwise asymptomatic infant or child. The importance of a PFO in some critical congenital heart defects (CHD), especially in neonates, is well recognized.

Cardiac IKs (KCNQ1/KCNE1) Channels
The cardiac IKs (KCNQ1/KCNE1) channel is one of the main contributors to the repolarizing currents that regulate the ventricular action potential duration (APD) and thus the QT interval in the electrocardiogram. Mutations in cardiac KCNQ1/KCNE1 channels are the most common cause of congenital defects that cause long QT syndrome (LQTS).

Bayés’ Syndrome
Interatrial block associated with atrial arrhythmias, mainly atrial fibrillation, define the Bayés’ Syndrome (called after Bayés de Luna, a proeminent cardiologist, who published the seminal paper about the problem of P-wave anomalies and interatrial blocks). Finding the signs of interatrial block on ECG represents a call for active screening of atrial fibrillation and starting of prophylactic anticoagulation in selected patients.

Pulse Wave Velocity
Pulse wave velocity (PWV) is a simple, reproducible and non-invasive technique to assess arterial stiffness. It estimates the velocity of arterial wave propagation to travel a known distance between two anatomic sites within the arterial system [1]. PWV has been established as an independent predictor of cardiovascular mortality and is consequently used for diagnosis and prognosis in patients at risk of atherosclerotic cardiovascular disease [2]; however, PWV's significance relies on the fact that arterial stiffness, specially of muscular arteries can be modified by interventions that improve endothelial function such as exercise training, which makes PWV an important tool for cardiovascular risk management [3].

Single Ventricle
In this paper, the author enumerates cardiac defects with a functionally single ventricle, summarizes single ventricle physiology, presents a summary of management strategies to address the single ventricle defects, goes over the steps of staged total cavo-pulmonary connection, cites the prevalence of inter-stage mortality, names the causes of inter-stage mortality, discusses strategies to address the inter-stage mortality, reviews post-Fontan issues, and introduces alternative approaches to Fontan circulation.

Advanced Glycation End Products and Cardiovascular Disease
Epidemiological studies demonstrate the role of early and intensive glycemic control in the prevention of micro and macrovascular disease in both type 1 and type 2 diabetes mellitus (DM). Hyperglycemia elicits several pathways related to the etiopathogenesis of cardiovascular disease (CVD), including the generation of advanced glycation end products (AGEs).

Licorice and the Cardiovascular System
Licorice is one of the oldest used herbs for medicinal purposes and consists of up to 300 active compounds. The main active constituent of licorice is the prodrug glycyrrhizin, which is successively converted to 3β-monoglucuronyl-18β-glycyrrhetinic acid (3MGA) and 18β-glycyrrhetinic acid (GA) in the intestines. Despite many reported health benefits, 3MGA and GA inhibit the 11-β-hydrogenase type II enzyme (11β-HSD2) oxidizing cortisol to cortisone. Through activation of mineralocorticoid receptors, high cortisol levels induce a mild form of apparent mineralocorticoid excess in the kidney and increase systemic vascular resistance. Continuous inhibition of 11β-HSD2 related to excess licorice consumption will create a state of hypernatremia, hypokalemia and increased fluid volume.
