Heart rate (HR) is an emerging risk factor in coronary artery disease (CAD). However, there is little contemporary data regarding HR and the use of HR-lowering medications, particularly beta-blockers, among patients with stable CAD in routine clinical practice. The goal of the present analysis was to describe HR in such ...

This paper examined whether nebivolol protects the heart via nitric oxide (NO) synthase and NO-dependent signaling in an in vivo model of acute myocardial infarction. Beta(3)-adrenergic receptor (AR) activation promotes endothelial nitric oxide synthase (eNOS) activity and NO bioavailability. We hypothesized that specific beta(3)-AR agonists would attenuate myocardial ischemia-reperfusion (MI/R) ...

Thymosin beta 4 (Tβ4) is a 43-amino acid factor encoded by an X-linked gene. Recent studies have suggested that Tβ4 is a key factor in cardiac development, growth, disease, epicardial integrity, and blood vessel formation. Cardiac-specific short hairpin (sh)RNA knockdown of tβ4 has been reported to result in embryonic lethality ...

Inability to achieve 85% of the maximum age-predicted heart rate (MPHR) on dobutamine stress echocardiography (DSE) is defined as chronotropic incompetence and is a predictor of major cardiac events after orthotopic liver transplantation (OLT). The majority of end-stage liver disease (ESLD) patients receive beta-blockers for prevention of variceal bleeding. In ...

A 72-year-old woman without cardiovascular history presented with acute substernal chest pain and dyspnoea. The electrocardiogram was normal, but the blood test analyses showed an elevated troponin T level. Emergency coronary angiography revealed normal epicardial coronary arteries, but the left ventriculogram demonstrated midventricular dilatation and akinesis with well-preserved contractility of ...

Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT) is an inherited arrhythmia syndrome, characterised by polymorphic ventricular tachycardia induced by adrenergic stress. CPVT can be caused by mutations the cardiac ryanodine receptor gene (RYR2) or mutations in the cardiac calsequestrin gene CASQ2. Structural heart disease is usually absent and the baseline ECG is ...

A 41-year-old woman with a history of neurocardiogenic syncope treated with beta-blockers was admitted with chest pain. Dobutamine echocardiogram images demonstrated decreased global LV systolic wall motion and thickening. Coronary angiograms were normal. Beta-blockers were stopped and dobutamine stress echocardiogram (DSE) was repeated. Dobutamine images demonstrated increased global LV systolic ...

The function of the right ventricle (RV) in heart failure (HF) has been mostly ignored until recently. A 2006 report of the National Heart, Lung, and Blood Institute identified a gap between RV research efforts and its clinical importance compared with that of the left ventricle. This recent shift in ...

Vitamin D has recently been suggested as an important mediator of blood pressure and cardiovascular disease, including heart failure. In patient with heart failure, low vitamin D levels are associated with adverse outcome and correlate with established clinical correlates and biomarkers. Many precursor states of heart failure, such as hypertension, ...

Chronic ischemia or pressure overload decreases thyroid hormone (TH) signaling and activates the fetal gene program in the heart. While these features are of physiologic importance in the developing heart, their respective roles in the postnatal heart are debated. Administration of TH can prevent the changes of the fetal gene ...

Secondary hyperparathyroidism (SHPT) may contribute to the systemic illness that accompanies chronic heart failure (CHF). Healthy elderly with vitamin D deficiency who did not develop hyperparathyroidism (functional hypoparathyroidism, FHPT) had lower mortality than those who did. This study was designed to examine determinants of the PTH response in the vitamin ...

As more patients survive myocardial infarctions, the incidence of heart failure increases. After an infarction, the human heart undergoes a series of structural changes, which are governed by cellular and molecular mechanisms in a pathological metamorphosis termed "remodeling." This review will discuss the current developments in our understanding of these ...

Glucagon-like peptide-1 (GLP-1) is involved in satiety control and glucose homeostasis. Besides, GLP-1 has cardiovascular effects. In experimental models, GLP-1 increases cardiac output and exerts a direct vasodilatory effect. In animals with dilated cardiomyopathy GLP-1 improves left ventricular performance. Human data demonstrated that GLP-1 reduces arterial blood pressure, improves endothelial ...

We report a case of a 78-year-old woman with cardiac sarcoidosis with a history of syncope and palpitation. Further assessment with echocardiography, gadolinium-enhanced cardiovascular magnetic resonance (CMR) and histology led to a diagnosis of cardiac sarcoidosis. As the patient suffered from ventricular tachycardia (VT) despite active corticosteroid therapy, an implantable ...

Heart failure is a major source of cardiovascular morbidity, including acute decompensations requiring hospitalization. Because most therapeutic interventions in acute heart failure target optimization of cardiac output and volume status, accurate assessment of these parameters at the point of care is critical to guide management. However, physician bedside assessments of ...

Chronic heart failure is a major public health problem causing considerable morbidity and mortality. Recent studies have shown that an elevated plasma level of homocysteine is a strong independent risk factor for heart failure, in addition to atherosclerotic disease. Preclinical studies have demonstrated that induced hyperhomocysteinemia acts via multiple pathogenic ...

Relaxin, a naturally-occurring hormone in the insulin family, was discovered to have a physiologic role in pregnancy. Named initially for its relaxing effect on the pubic ligament, relaxin receptors have since been found to be widely distributed in many organs in both males and females. Acting through multiple pathways, including ...

Background: Certain cardiac-specific autoantibodies found in patients with dilated cardiomyopathy (DCM) play a role in mediating myocardial damage and fatal ventricular arrhythmias resulting in sudden cardiac death. Immunoadsorption therapy (IA) is one of the therapeutic tools to remove such autoantibodies. Clinical studies from Germany have shown that nonspecific IA using ...

Acute right ventricular (RV) failure is a frequent and serious clinical challenge in the intensive care unit. It is usually seen as a consequence of left ventricular failure, pulmonary embolism, pulmonary hypertension, sepsis, acute lung injury or after cardiothoracic surgery. The presence of acute RV failure not only carries substantial ...
