Summary

Hypertension is a major public health concern worldwide because of its rising prevalence and concomitant risks of cardiovascular diseases. Coping strategies may encompass a full spectrum of clinical, epidemiological, experimental, and technological factors to inspire front-line practices and shape critical thinking. This entry collection aims to assemble entries of wealthy topics related to clinical, therapeutic, and population sciences of hypertension and cardiovascular diseases that could inform research scientists and healthcare professionals.

CNPase
As an unconventional PDE, CNPase catalyzes 2′,3′-cyclic nucleotides as substrates [9], which are reported to impair mitochondrial integrity and accelerate the opening of the mitochondrial permeability transition pore (mPTP). As a mitochondrial protein, protein–protein interactions between the functional complexes I–V of the mitochondrial inner membrane and CNPase, leads to the assumption that CNPase might be involved in mitochondrial respiration and energy production.

MicroRNAs in Valvular Heart Diseases
microRNAs (miRNAs) have been documented to be regulators of valvular diseases pathogenesis, diagnostic biomarkers, and therapeutical targets. They in fact play stimulatory or inhibitory roles in mitral valve prolapse development, aortic leaflet fusion, and calcification pathways. Tissue expression assessment and comparison between physiological and pathological phenotypes of different disease entities, including mitral valve prolapse and mitral chordae tendineae rupture, emerged as the best strategies to address miRNAs over or under-representation and thus, their impact on pathogeneses. miRNAs can also be targeted by several molecules. Inhibitors such as antisense oligonucleotides and sponge vectors are under investigation. Furthermore, to increase miRNAs activity miRNA mimics, miRNA expression vectors, and small molecules have been developed.

Changes in Cardiac Metabolism in Prediabetes
In type 2 diabetes mellitus (T2DM), there is an increased prevalence of cardiovascular disease (CVD), even when corrected for atherosclerosis and other CVD risk factors. Diastolic dysfunction is one of the early changes in cardiac function that precedes the onset of cardiac failure, and it occurs already in the prediabetic state.

Homocysteine Solution-Induced Response in OECTs Devices
Homocysteine (Hcy) is a non-protein, sulfur-containing amino acid, which is recognized as a possible risk factor for coronary artery and other pathologies when its levels in the blood exceed the normal range of between 5 and 12 μmol/L (hyperhomocysteinemia). At present, standard procedures in laboratory medicine, such as high-performance liquid chromatography (HPLC), are commonly employed for the quantitation of total Hcy (tHcy), i.e., the sum of the protein-bound (oxidized) and free (homocystine plus reduced Hcy) forms, in biological fluids (particularly, serum or plasma). Here, the response of Aerosol Jet-printed organic electrochemical transistors (OECTs), in the presence of either reduced (free) and oxidized Hcy-based solutions, was analyzed. Two different experimental protocols were followed to this end: the former consisting of gold (Au) electrodes’ biothiol-induced thiolation, while the latter simply used bare platinum (Pt) electrodes. Electrochemical impedance spectroscopy (EIS) analysis was performed both to validate the gold thiolation protocol and to gain insights into the reduced Hcy sensing mechanism by the Au-gated OECTs, which provided a final limit of detection (LoD) of 80 nM. For the OECT response based on Platinum gate electrodes, on the other hand, a LoD of 180 nM was found in the presence of albumin-bound Hcy, with this being the most abundant oxidized Hcy-form (i.e., the protein-bound form) in physiological fluids. Despite the lack of any biochemical functionalization supporting the response selectivity, the findings discussed in this work highlight the potential role of OECT in the development of low-cost point-of-care (POC) electronic platforms that are suitable for the evaluation, in humans, of Hcy levels within the physiological range and in cases of hyperhomocysteinemia.

Left Ventricular Hypertrophy Pathophysiology
Left ventricular hypertrophy (LVH) can be adaptive, as arising from exercise, or pathological, most commonly when driven by hypertension. The pathophysiology of LVH is consistently associated with an increase in cytochrome P450 (CYP)1B1 and mitogen-activated protein kinases (MAPKs) and a decrease in sirtuins and mitochondria functioning. The pathoetiology of LVH is intimately associated with increased blood pressure and therefore with the array of different factors associated with hypertension, including the various manifestations and consequences of stress, obesity and diabetes.

Clinical Molecular Imaging for Atherosclerotic Plaque
Atherosclerosis is a well-known disease leading to cardiovascular events, including myocardial infarction and ischemic stroke. These conditions lead to a high mortality rate, which explains the interest in their prevention, early detection, and treatment. Molecular imaging is able to shed light on the basic pathophysiological processes, such as inflammation, that cause the progression and instability of plaque.

Marine-Derived Omega-3 Polyunsaturated Fatty Acids and Heart Failure
Heart failure (HF) is a rapidly growing global public health problem. Since HF results in high mortality and re-hospitalization, new effective treatments are desired. Although it remains controversial, omega 3 polyunsaturated fatty acids (n-3 PUFAs), such as the eicosapentaenoic acid and docosahexaenoic acid, have been widely recognized to have benefits for HF.

Effect of Resveratrol on the Cardiovascular System
RES (3,5,4-trihydroxystilbene), a natural phytoalexin found in a wide variety of plants (e.g., nuts, berries, and grapes) is produced in response to environmental stress. RES exists as two geometric isomers: cis-(Z) and trans-(E). Trans- and cis-resveratrol can be either free or bound to glucose.

Preoperative Planning for Superior Mesenteric Artery Aneurysm
Surgical procedures on various artery aneurysms are difficult to perform and require careful preparation. We have developed a software platform, CardioCTNav, that can help in planning such procedures. The planning consists of a 3D rendering of the area of interest, virtual angiography, automated measurements, and virtual stent simulation.

Ultrasound Assessment in Cardiogenic Shock Weaning
Cardiogenic shock (CS) is associated with a high in-hospital mortality despite the achieved advances in diagnosis and management. Invasive mechanical ventilation and circulatory support constitute the highest step in cardiogenic shock therapy. Once established, taking the decision of weaning from such support is challenging. Intensive care unit (ICU) bedside echocardiography pro- vides noninvasive, immediate, and low-cost monitoring of hemodynamic parameters such as cardiac output, filling pressure, structural disease, congestion status, and device functioning. Supplemented by an ultrasound of the lung and diaphragm, it is able to provide valuable information about signs suggesting a weaning failure. The aim of this article was to review the state of the art taking into account current evidence and knowledge on ICU bedside ultrasound for the evaluation of weaning from mechanical ventilation and circulatory support in cardiogenic shock.
