There is ample evidence on the benefit of angiotensin receptor-neprilysin inhibitors (ARNIs) in heart failure, yet data regarding the potential protective action of ARNIs in hypertensive heart disease are sparse. The aim of this study was to show whether an ARNI exerts a protective effect in a model of Nω-nitro-L-arginine methyl ester (L-NAME)-indu...
This study investigated whether sacubitril/valsartan or valsartan are able to prevent left ventricular (LV) fibrotic remodelling and dysfunction in two experimental models of pre-hypertension induced by continuous light (24 hours/day) exposure or by chronic lactacystin treatment, and how this potential protection interferes with the renin-angiotens...
This study investigated whether chronic isoproterenol administration could induce kidney alterations and whether ivabradine, a heart rate (HR)-reducing substance exerting cardiovascular protection, is able to attenuate potential kidney damage. Twenty-eight Wistar rats were divided into non-diseased controls, rats treated with ivabradine, rats treat...
Anxiety disorders are the most common mental diseases. Anxiety and the associated physical symptoms may disturb social and occupational life and increase the risk of somatic diseases. The pathophysiology of anxiety development is complex and involves alterations in stress hormone production, neurosignaling pathways or free radical production. The v...
Lactacystin is a specific proteasome inhibitor that blocks the hydrolysis of intracellular proteins by ubiquitin/proteasome system inhibition. The administration of lactacystin to rats induced hypertension and remodeling of the left ventricle and aorta. This study tested whether lactacystin induces structural and fibrotic rebuilding of the kidneys...
This study investigated whether sacubitril/valsartan and ivabradine are able to prevent left ventricular (LV) fibrotic remodelling and dysfunction in a rat experimental model of spontaneous hypertension (spontaneously hypertensive rats, SHRs) and whether this potential protection is associated with RAAS alterations. Five groups of three-month-old m...
Besides the well-recognized risk factors, novel conditions increasing cardiovascular morbidity and mortality are emerging. Undesirable emotions and behavior such as anxiety and depression, appear to participate in worsening cardiovascular pathologies. On the other hand, deteriorating conditions of the heart and vasculature result in disturbed menta...
Experimental and clinical studies from recent decades provided evidence supporting the hypothesis that the heart’s endocrine function is part of the neurohumoral network. The natriuretic peptide system consists of hormones generated by the myocardium having similar cardioprotective effects involved in cardiovascular homeostasis. During hemodynamic...
This study investigated whether ivabradine, a selective If current inhibitor reducing heart rate (HR), is able to improve survival and prevent left ventricular (LV) remodeling in isoproterenol‐induced heart damage. Wistar rats were treated for 6 weeks: controls (n = 10), ivabradine (10 mg/kg/day orally; n = 10), isoproterenol (5 mg/kg/day intraperi...
Hypertension-induced renal injury is characterized by structural kidney alterations and function deterioration. Therapeutics for kidney protection are limited, thus novel renoprotectives in hypertension are being continuously sought out. Ivabradine, an inhibitor of the I f current in the sinoatrial node reducing heart rate (HR), was shown to be of...
This study investigated the effect of lisinopril (angiotensin-converting enzyme inhibi-tor) on potential behavioural alterations in spontaneously hypertensive rats (SHR). Three groups of 15-17-week-old rats were investigated for 2 weeks: Wistar control group, SHR group and SHR+lisinopril group. Systolic blood pressure (SBP) was normal in Wistar rat...
There is a great urgency of detecting and monitoring myocardial fibrosis in clinical practice with the aim to improve and personalize therapy against cardiac remodelling. Hence, the aim of this study was to describe alterations in and show potential correlations between the structural characteristics and the molecular and biochemical markers of car...
Cardiovascular pathologies are frequently associated with anxiety and other behavioral disturbances. Ivabradine, an inhibitor of the hyperpolarization-activated cyclic nucleotide-gated channels in the sinoatrial node, decreases heart rate and provides cardiovascular protection. Although ivabradine is increasingly used in cardiovascular medicine, th...
Ivabradine, the selective inhibitor of the If current in the sinoatrial node, exerts cardiovascular protection by its bradycardic effect and potentially pleiotropic actions. However, there is a shortage of data regarding ivabradine’s interaction with the renin-angiotensin-aldosterone system (RAAS). This study investigated whether ivabradine is able...
This study investigated whether continuous light exposure (CLE) results in behavioural disturbances in rats and whether melatonin can modify these potential changes. Four groups of 3-month-old Wistar rats were treated as follows for six weeks: control, melatonin, CLE, and CLE with melatonin. CLE increased systolic blood pressure and melatonin reduc...
No data are available on heart function in chronic testosterone deficiency and on the effect of estrogen treatment. Eighteen 4-week-old male Lewis rats were randomly divided into three groups (n = 6): one group of sham-operated rats and two groups of castrated rats. 66 weeks after surgery, one castrated group received a dose of 17β-estradiol (10 μg...
The renin-angiotensin-aldosterone system (RAAS) is a dominant player in several cardiovascular pathologies. This study investigated whether alterations induced by l-NAME, (NLG)-nitro-l-arginine methyl ester, a nitric oxide synthase inhibitor, and the protective effect of melatonin are associated with changes in the RAAS. Four groups of 3-month-old...
Abstrakt: Aims: The mutual interrelation between cardiovascular diseases and anxiety disorder has been frequently discussed. The aim of this study was to show whether L-NAME (N[omega]-nitro-L-arginine methyl ester)-induced hypertension could induce behavioural disturbances in rats and whether these potential disorders could be modified by chronic t...
Lactacystin is a proteasome inhibitor that interferes with several factors involved in heart remodelling. The aim of this study was to investigate whether the chronic administration of lactacystin induces hypertension and heart remodelling and whether these changes can be modified by captopril or melatonin. In addition, the lactacystin-model was co...
Cardiovascular diseases including hypertension are often associated with behavioural alterations. The aim of this study was to show, whether ivabradine, the blocker of If-channel in sinoatrial node, is able to modify the behaviour of rats in L-nitro-arginine methyl ester (L-NAME)-induced hypertension and to compare the effect of ivabradine with cap...
Chronic kidney disease (CKD) is a serious public health problem. Current therapies are designed to slow down progression of the disease and avoid the necessity of dialysis or kidney transplantation. CKD is characterized by chronic inflammation and progressive cell death resulting in fibrotic rebuilding of renal tissue. Melatonin, the primary produc...
Chronic continuous light exposure leads to melatonin deficiency along with complex neurohumoral activation resulting in hypertension development in rats. The aim of this study was to show, whether continuous light induces fibrotic rebuilding of the aorta and whether the treatment with melatonin or angiotensin converting enzyme inhibitor captopril c...
Chronic kidney disease (CKD) represents a serious public health problem with increasing prevalence and novel approaches to renal protection are continuously under investigation. The aim of this study was to compare the effect of melatonin and angiotensin II type 2 receptor agonist compound 21 (C21) to angiotensin converting enzyme inhibitor captopr...
