Palmitoleic Acid Protects against Hypertension by Inhibiting NF-κB-Mediated Inflammation.

Mol Nutr Food Res 2021 Apr 17:e2001025. Epub 2021 Apr 17.

Department of Food Science and Nutrition, Zhejiang University, Hangzhou, China.

Scope: The role of palmitoleic acid (POA) in hypertension or blood pressure remains uncertain.

Determinants of cardiac structure in frail and sarcopenic elderly adults.

Exp Gerontol 2021 Apr 14:111351. Epub 2021 Apr 14.

Department of Medicine and Surgery, University Medical School of Parma, Parma, Italy; University-Hospital of Parma, Parma, Italy; Geriatric Clinic Unit, University-Hospital of Parma, Parma, Italy.

Background: Cardiac structure and function change with age. The higher prevalence of left ventricular hypertrophy (LVH) with concentric remodeling is indicative of a typical geometric pattern of aging associated with a higher cardiovascular (CV) risk and diseases. The recent associations found between low left ventricular and skeletal mass in older patients with frailty and sarcopenia have raised great interest in investigating cardiac characteristics and determinants of left ventricular mass (LVM) in this population.

Heart-lung interactions in COVID-19: prognostic impact and usefulness of bedside echocardiography for monitoring of the right ventricle involvement.

Authors:
Michael Dandel

Heart Fail Rev 2021 Apr 17. Epub 2021 Apr 17.

German Centre for Heart and Circulatory Research (DZHK) Partner Site, Berlin, Berlin, Germany.

Due to the SARS-CoV-2 infection-related severe pulmonary tissue damages associated with a relative specific widespread thrombotic microangiopathy, the pathophysiologic role of heart-lung interactions becomes crucial for the development and progression of right ventricular (RV) dysfunction. The high resistance in the pulmonary circulation, as a result of small vessel thrombosis and hypoxemia, is the major cause of right heart failure associated with a particularly high mortality in severe COVID-19. Timely identification of patients at high risk for RV failure, optimization of mechanical ventilation to limit its adverse effects on RV preload and afterload, avoidance of medication-related increase in the pulmonary vascular resistance, and the use of extracorporeal membrane oxygenation in refractory respiratory failure with hemodynamic instability, before RV failure develops, can improve patient survival.

The AT-1 Angiotensin Receptor is Involved in the Autonomic and Neuroendocrine Responses to Acute Restraint Stress in Male Rats.

Cell Mol Neurobiol 2021 Apr 16. Epub 2021 Apr 16.

Department of Pharmacology of the School of Medicine of Ribeirão Preto, University of São Paulo, Ave. Bandeirantes, São Paulo, Ribeirão Preto, 3900-14049-900, Brazil.

The renin-angiotensin system (RAS) is involved in cardiovascular and hydroelectrolytic control, being associated with the development of hypertension. The restraint stress (RS) model is an aversive situation, which promotes a sustained increase in blood pressure and heart rate, and stimulation of the hypothalamic-pituitary-adrenal axis. Stress leads to an increase of angiotensin-II contents both in the circulation and the central nervous system (CNS), as well as an increased expression of AT-1 receptors in CNS structures related to stress.

Pulmonary Arterial Hypertension: Diagnosis, Treatment, and Novel Advances.

Am J Respir Crit Care Med 2021 Apr 16. Epub 2021 Apr 16.

Columbia University Medical Center, 21611, New York, New York, United States.

The diagnosis and management of pulmonary arterial hypertension (PAH) includes several advances, such as broader recognition of extra-pulmonary vascular organ system involvement, validated point-of-care clinical assessment tools, and a focus on early-initiation of multiple pharmacotherapeutics in appropriate patients. Indeed, a principal goal in PAH today is early diagnosis for prompt initiation of treatment to achieve minimal symptom burden, optimize the patient's biochemical, hemodynamic, and functional profile, and limit adverse events. To accomplish this end, clinicians must be familiar with novel risk factors and the revised hemodynamic definition for PAH. Read More

Targeting Adenosine Receptors in Neurological Diseases.

Cell Reprogram 2021 Apr;23(2):57-72

Department of Clinical Nutrition, NUR International University, Lahore, Pakistan.

Adenosine plays a significant role in neurotransmission process by controlling the blood pressure, while adenosine triphosphate (ATP) acts as a neuromodulator and neurotransmitter and by activation of P2 receptors, regulates the contractility of the heart. Adenosine signaling is essential in the process of regeneration by regulating proliferation, differentiation, and apoptosis of stem cells. In this review, we have selected neurological disorders (Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, and epilepsy) with clinical trials using antagonists and epigenetic tools targeting adenosine receptor as a therapeutic approach in the treatment of these disorders.

Trajectories of Blood Pressure Control a Year after Randomization and Incident Cardiovascular Outcomes in SPRINT.

Am J Hypertens 2021 Apr 16. Epub 2021 Apr 16.

Section of Cardiology, Department of Internal Medicine, Wake Forest School of Medicine, Winston-Salem, NC.

Background: While studies have assessed the association between blood pressure trajectories and cardiovascular disease (CVD) outcomes using observational data, few have assessed these associations using clinical trial data. We sought to identify systolic blood pressure (SBP) trajectories and to determine if these trajectory patterns carry inherent CVD risk, irrespective of baseline blood pressure.

Methods: SBP trajectories were identified using latent class group based modeling among a cohort of 8901Systolic Blood Pressure Intervention Trial (SPRINT) participants by incorporating SBP measures during the first 12 months of the trial post randomization. Read More
