Cardiorenal Signaling Pathways in Heart Failure: Good and Bad News
Journal Title: Journal of Hypertension and Cardiology - Year 2015, Vol 1, Issue 4
Abstract
Despite significant improvements in the treatment of virtually all cardiac disorders, heart failure (HF) is an exception, its prevalence is increasing, and only small extensions occur in survival. Several pathogenetic mechanisms appear to be operative in HF. These include higher overhead hemodynamic dysfunction associated with ventricular ischemia, remodeling with neurohumoral excessive stimulation, myocyte cycling abnormal calcium, inadequate or excessive proliferation of the extracellular matrix, accelerated apoptosis and genetic mutations. HF can present with reduced ejection fraction (EF), HFrEF, or with preserved EF (HFpEF). The interplay between diverse organ systems contributing to HF is mediated by the activation of counteracting neurohormonal pathways focused to re-establishing hemodynamic homeostasis. Cardiorenal Syndrome is a specific condition which is characterized by a rapid or chronic worsening of cardiac function leading to acute or chronic kidney injury (A/CKI) and /or the reciprocal organ dysfunction sequence can be possible. Even though its pathophysiology is complex and not still completely understood, oxidative stress and endothelial dysfunction seems to play a pivotal role. New Pathways between heart and kidney and its early recognition can also be targeted for more effective and beneficial HF treatments.

Intercoronary Continuity with Bidirectional Flow: Dynamic Changes Parallel to Coronary Disease Progression
Direct intercoronary continuity is a rare angiographic finding. We report an unusual case of a 51-year old male with coronary disease who demonstrated intermittent variability in the directions of flow as a result of cha...
Intermediate-Dose Enoxaparin After Cardiac Ablation Procedures
Objective: Ablation of foci within the atria has been shown to resolve symptoms of atrial fibrillation and atrial flutter. However, no standard has been established for anticoagulation after the procedure. Enoxaparin ha...
