The no-reflow phenomenon is a poorly understood complication of percutaneous coronary intervention in which diminished blood flow to distal microvascular beds persists despite the successful treatment of the occlusive lesion from the epicardial coronary artery or arteries. In this contemporary review we endeavour to discuss the pathophysiology of coronary no-reflow, understand the predictors and describe curre Read More

The decision to anti-coagulate patients with heart failure (HF) is a difficult one, with limited data available to support clinical judgment. Thromboembolic complications, both arterial (stroke) and venous (deep vein thrombosis and pulmonary embolism), remain a significant cause of mortality and morbidity in this population. The pathophysiology of thrombogenesis in HF may be contextualized in the classic triad of sta Read More

Epidemiological studies suggest a strong association between hypertension and ischemic heart disease (IHD), and hypertension is a major independent risk factor for the development of cardiovascular disease (CVD) including myocardial infarction (MI) and stroke. The primary objective of the management of hypertension in patients with IHD is modification of the balance between myocardial oxygen supply and demand Read More

Cyclic adenosine 3'5'-monophosphate (cAMP) and cyclic guanosine 3'5'-monophosphate (cGMP) are critical intracellular messengers involved in transduction of signals generated by a wide variety of extracellular stimuli, including growth factors, cytokines, peptide hormones, light and neurotransmitters. These messengers modulate many fundamental biological processes, including myocardial contractility, platelet agg Read More

Endothelial dysfunction is characterized by an impairment of endothelium-dependent vasodilatation. It has been linked to each of the known atherogenic risk factors, including diabetes mellitus, hypertension, dyslipidaemia, cigarette smoking, menopause, etc. A number of recent studies have shown that the severity of endothelial dysfunction correlates with the development of coronary artery disease and predicts future Read More

Respiratory syncytial virus (RSV) is a very important pathogen worldwide. It occurs and recurs naturally throughout life. Both short and long term morbidity, and mortality are particularly significant for infants, especially those infants with underlying conditions and risk factors. Current treatment strategies for these patients (e.g Ribavirin) are limited but several new interventions (e.g. RSV604, BTA9881, ALN-RSV01) are Read More

The plasma kallikrein-kinin system (KKS) plays a critical role in human physiology. The KKS encompasses coagulation factor XII (FXII), the complex of prekallikrein (PK) and high molecular weight kininogen (HK). The conversion of plasma prekallikrein to kallikrein by the activated FXII and in response to numerous different stimuli leads to the generation of bradykinin (BK) and activated HK (HKa, an antiangiogenic peptide). BK Read More

Single nucleotide polymorphisms (SNP) in the CYBA gene encoding p22phox have been associated with respiratory burst and cardiovascular phenotypes. We previously reported a reduced phagocytic respiratory burst activity in healthy adults with the C242T SNP, but found no correlation between CYBA SNPs and coronary artery disease (CAD) phenotype. Using lymphoblastoid cells, we hypothesized that CYBA SNPs affect e Read More
