BACKGROUND: The HALT PKD trial in early autosomal dominant polycystic kidney disease (ADPKD) showed that intensive control of systolic blood pressure to 95-110 mmHg was associated with a 14% slower rate of kidney volume growth compared to standard control. It is unclear whether this result was due to greater blockade of the renin-angiotensin-aldosterone system (RAAS) by allowing the use of higher drug doses in the low blood pressure arm, or due to the lower blood pressure per se. METHODS: In this secondary analysis of HALT PKD Study A, we categorized participants into high and low dose groups based on the median daily equivalent dose of RAAS blocking drugs used after the initial dose titration period...

Platelets and the coagulation cascade play key roles in initiation, amplification, and perpetuation of acute coronary syndromes (ACS). In the past few years, there has been great progress in ACS antithrombotic treatment with the introduction of novel anticoagulants (fondaparinux and bivalirudin), more potent P2Y12 inhibitors (prasugrel and ticagrelor) and protease-activated receptor antagonists (vorapaxar). Nonetheless, patients with ACS frequently have recurrent ischemic events despite the use of currently recommended dual antiplatelet therapy, revascularization procedures as appropriate, and other evidence-based secondary preventive measures...

Antineoplastic drugs can be associated with several side effects, including cardiovascular toxicity (CTX). Biochemical studies have identified multiple mechanisms of CTX. Chemoterapeutic agents can alter redox homeostasis by increasing the production of reactive oxygen species (ROS) and reactive nitrogen species RNS. Cellular sources of ROS/RNS are cardiomyocytes, endothelial cells, stromal and inflammatory cells in the heart. Mitochondria, peroxisomes and other subcellular components are central hubs that control redox homeostasis...
