BACKGROUND: Relaxin-2 (RLX) is a peptide hormone that exerts beneficial anti-fibrotic and anti-inflammatory effects in diverse models of cardiovascular disease. The goal of this study was to determine the effects of RLX treatment on the susceptibility to atrial fibrillation (AF) after myocardial infarction (MI). METHODS: Mice with cryoinfarction of the left anterior ventricular wall were treated for two weeks with either RLX (75 μg/kg/d) or vehicle (sodium acetate) delivered via subcutaneously implanted osmotic minipumps...

AIMS: There is significant evidence that the endocannabinoid system (ECS) takes part in the regulation of the cardiovascular system in hypertension. It is quite well established that hypertension causes several changes in the heart metabolism, but it is still unknown whether the ECS affects this process. Therefore, we investigated the influence of prolonged ECS activation on myocardial lipid metabolism in deoxycorticosterone acetate (DOCA)-salt hypertensive rats by chronic fatty acid amide hydrolase (FAAH) inhibition...

INTRODUCTION: Congenital variants of the cervical spine may mimic traumatic lesions and may cause recurrent episodes of pain. The spectrum of cervical variants includes persistent apophyses of the transverse processes, persistent epiphyses, vertebral platyspondylia, vertebral hypoplasia, and dysplasia of the vertebral arch. Furthermore, abnormalities of the spinous process have been described including doubled spinous processes and hypertrophies. Unilateral hyperplasia of a spinous process is a rare finding that has only been described rarely as case reports...

Betaine Aldehyde Dehydrogenase (betaine aldehyde: NAD(P)(+) oxidoreductase, (E.C. 1.2.1.8; BADH) catalyze the irreversible oxidation of betaine aldehyde (BA) to glycine betaine (GB) and is essential for polyamine catabolism, γ-aminobutyric acid synthesis, and carnitine biosynthesis. GB is an important osmolyte that regulates the homocysteine levels, contributing to a vascular risk factor reduction. In this sense, distinct investigations describe the physiological roles of GB, but there is a lack of information about the GB novo synthesis process and regulation during cardiac hypertrophy induced by pregnancy...

BACKGROUND: Whether increasing body mass index (BMI) is independently associated with parallel increased prevalence of hypertensive vascular and cardiac target organ damage (TOD) needs further clarification. METHODS: We analyzed 8815 hypertensive patients without prevalent cardiovascular disease, participating in the Campania Salute Network, grouped into BMI classes (normal 20-24.9kg/m(2), overweight 25-29.9kg/m(2) and obese ≥30kg/m(2)). Vascular and cardiac TOD was defined as ultrasound plaque (intima-media thickness>1...

Right ventricular failure (RVF) is the most important prognostic factor for both morbidity and mortality in pulmonary arterial hypertension (PAH), but also occurs in numerous other common diseases and conditions, including left ventricle dysfunction. RVF remains understudied compared with left ventricular failure (LVF). However, right and left ventricles have many differences at the morphological level or the embryologic origin, and respond differently to pressure overload. Therefore, knowledge from the left ventricle cannot be extrapolated to the right ventricle...

It has been suggested that renal denervation (RD) may attenuate left ventricular (LV) hypertrophy. However, the role that autophagy serves in this process is currently unclear. In the present study, utilizing a model of hypertension‑induced cardiac hypertrophy in spontaneous hypertensive rats, it was demonstrated that RD was significantly associated with a reduction in LV hypertrophy. Furthermore, a decrease in the myocardial mRNA of hypertrophy‑associated genes was demonstrated in RD rats compared with sham controls...

BACKGROUND: Electrocardiography (ECG), predictive of adverse outcomes in the general population, has not been studied in cancer survivors. We evaluated the prevalence of ECG abnormalities and associations with mortality among childhood cancer survivors. METHODS: Major and minor abnormalities were coded per the Minnesota Classification system for participants in the St Jude Lifetime Cohort Study (n = 2,715) and community controls (n = 268). Odds ratios (ORs) and 95% CIs were calculated using multivariable logistic regression; and hazard ratios, using Cox proportional hazards regression...

BACKGROUND: Poor glycemic control is associated with impaired left ventricular (LV) diastolic function in patients with type 2 diabetes mellitus (T2DM). Inappropriate LV mass increase and accelerated aortic stiffening were suggested to participate on deterioration of diastolic function. The present study investigated the inter-relationships between glycemic control, early diastolic and systolic longitudinal velocity of mitral annulus, LV mass and aortic stiffness in T2DM patients free of cardiovascular disease and with preserved LV ejection fraction, and compared them with those observed in healthy volunteers of similar age and sex distribution...

The electrocardiogram (ECG) presents substantial changes associated with aging. In fact, the likelihood of having a "normal" ECG decreases with age. The most common findings are left ventricular hypertrophy pattern, leftward axis deviation and QRS widening. Interatrial block (IAB) is frequently present, mainly partial IAB. Atrial fibrillation prevalence raises from 6-7% in those aged 65-74years to 13-17% in those >75years.

Aerobic exercise confers sustainable protection against cardiac hypertrophy and heart failure (HF). Nitric oxide synthase (NOS) and nitric oxide (NO) are known to play an important role in exercise-mediated cardioprotection, but the mechanism of NOS/NO stimulation during exercise remains unclear. The aim of this study is to determine the role of β3-adrenergic receptors (β3-ARs), NOS activation, and NO metabolites (nitrite and nitrosothiols) in the sustained cardioprotective effects of aerobic exercise. An HF model was constructed by transverse aortic constriction (TAC)...

We evaluated the prognostic impact of a complex remodeling classification (CRC) in asymptomatic patients with arterial hypertension (AH). We retrospectively included 749 hypertensive patients (female 325, 43.4% age 62 ± 11.3 years) in Stages A and B of heart failure. CRC was evaluated including indexed left ventricular mass, end-diastolic volume, and relative wall thickness. After 45-month follow-up, we considered a composite endpoint: total mortality, myocardial infarction, myocardial revascularization, cerebrovascular events, and acute pulmonary edema...

Recently, PSEN1 has been reported to have mutations in dilated cardiomyopathy pedigrees. However, the function and mechanism of PSEN1 in cardiomyopathy remains unresolved. Here, we established 4 types of genetically modified mice to determine the function of PSEN1 in cardiac development and pathology. PSEN1 null mutation resulted in perinatal death, retardation of heart growth, ventricular dilatation, septum defects, and valvular thickening. PSEN1 knockout in adults led to decreased muscle fibers, widened sarcomere Z lines and reduced lengths of sarcomeres in cardiomyocytes...

Deep-space travel presents risks of exposure to ionizing radiation composed of a spectrum of low-fluence protons ((1)H) and high-charge and energy (HZE) iron nuclei (e.g., (56)Fe). When exposed to galactic cosmic rays, each cell in the body may be traversed by (1)H every 3-4 days and HZE nuclei every 3-4 months. The effects of low-dose sequential fractionated (1)H or HZE on the heart are unknown. In this animal model of simulated ionizing radiation, middle-aged (8-9 months old) male C57BL/6NT mice were exposed to radiation as follows: group 1, nonirradiated controls; group 2, three fractionated doses of 17 cGy (1)H every other day ((1)H × 3); group 3, three fractionated doses of 17 cGy (1)H every other day followed by a single low dose of 15 cGy (56)Fe two days after the final (1)H dose ((1)H × 3 + (56)Fe); and group 4, a single low dose of 15 cGy (56)Fe followed (after 2 days) by three fractionated doses of 17 cGy (1)H every other day ((56)Fe + (1)H × 3)...
