BACKGROUND: Acquired thrombotic thrombocytopenic purpura (aTTP) is a life-threatening autoimmune thrombotic microangiopathy. In spite of treatment with plasma exchange and immunosuppression, patients remain at risk for thrombotic complications, exacerbations and death. In the Phase II TITAN study, treatment with caplacizumab, an anti-vWF Nanobody(®) , was shown to reduce the time to confirmed platelet count normalization and exacerbations during treatment. OBJECTIVE: The clinical benefit of caplacizumab was further investigated in a post-hoc analysis of the incidence of major thromboembolic events and exacerbations during the study drug treatment period and TTP-related death during the study...

BACKGROUND: Peripheral artery disease (PAD) in heart failure with preserved ejection fraction (HFpEF) is associated with an increased mortality risk, but the risk of individual outcomes associated with PAD in this patient group is less clear. HYPOTHESIS: PAD is associated with adverse outcomes in HFpEF, including hospitalization and specific cardiovascular outcomes. METHODS: We examined the association between PAD and adverse outcomes in 3385 patients with HFpEF (mean age, 69 ± 9...

Despite the increase in use of percutaneous coronary intervention (PCI) in left main coronary disease, its efficacy compared with coronary artery bypass grafting (CABG) is unclear. We performed a meta-analysis of randomized controlled trials to assess the optimal revascularization strategy. Our search yielded 8 studies reporting relevant outcomes that were pooled using the inverse variance method, and the hazard ratio (HR) was calculated. The primary outcome was all-cause mortality, myocardial infarction (MI), or stroke (major adverse cardiac events [MACE]), and the secondary outcome was death/MI/stroke/repeat revascularization (expanded MACE)...

Lauren D C Casa, David N Ku
The final common pathway in myocardial infarction and ischemic stroke is occlusion of blood flow from a thrombus forming under high shear rates in arteries. A high-shear thrombus forms rapidly and is distinct from the slow formation of coagulation that occurs in stagnant blood. Thrombosis at high shear rates depends primarily on the long protein von Willebrand factor (vWF) and platelets, with hemodynamics playing an important role in each stage of thrombus formation, including vWF binding, platelet adhesion, platelet activation, and rapid thrombus growth...

That hypertensive disorders of pregnancy (HDP) affect maternal health even after delivery of the baby and the placenta, is no longer in doubt. Women with a history of HDP, preeclampsia in particular, have well-documented increased risks of later hypertension, ischemic heart disease, myocardial infarction, ischemic stroke, venous thromboembolism, and cardiomyopathy. However, our understanding of how "later" is defined - i.e. when exactly HDP-associated disease risks increase - is shifting. This article is protected by copyright...

Type 2 diabetic patients are known to have a tendency to develop cardiovascular (CV) disease (CVD), and related unfavourable outcomes such as heart failure, myocardial infarction (MI), cerebrovascular events (eg. stroke), and related mortality. Long- term clinical trials have revealed contradictory findings regarding the relationship between glycemic control and CV benefits due to variations in the key characteristics of the study population. During the last decade, number of pharmacological agents used for glucose- lowering in the treatment of type 2 diabetes mellitus (T2DM) has increased owing to the introduction of dipeptidyl peptidase- IV (DPP- IV) inhibitors, glucagon- like peptide- 1 (GLP- 1) receptor agonists, and sodium-glucose co-transporter 2 (SGLT- 2) inhibitors...

Obstructive sleep apnoea (OSA) is associated with increased risk of cardiovascular and cerebrovascular disease, a consequence attributed in part to chronic intermittent hypoxia (IH) resulting from repetitive apnoeas during sleep. Although findings from experimental animal, and human, models have shown that IH is detrimental to vascular regulation, the severity of IH used in many of these animal studies (e.g. inspired fraction of oxygen (FI O2 ) = 2-3%; oxygen desaturation index (ODI) = 120 events h(-1) ) is considerably greater than that observed in the majority of patients with OSA...

Ischemic heart disease is the main cause of death worldwide and is accelerated by increased levels of low-density lipoprotein cholesterol (LDL-C). Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a potent circulating regulator of LDL-C through its ability to induce degradation of the LDL receptor (LDLR) in the lysosome of hepatocytes. Only in the last few years, a number of breakthroughs in the understanding of PCSK9 biology have been reported illustrating how PCSK9 activity is tightly regulated at several levels by factors influencing its transcription, secretion, or by extracellular inactivation and clearance...

The human body has a set of physiological processes, known as hemostasis, which keeps the blood fluid and free of clots in normal vessels; in the case of vascular injury, this process induces the local formation of a hemostatic plug, preventing hemorrhage. The hemostatic system in humans presents complex physiological interactions that involve platelets, plasma proteins, endothelial and subendothelial structures. Disequilibrium in the regulatory mechanisms that control the growth and the size of the thrombus is one of the factors that favors the development of diseases related to vascular disorders such as myocardial infarction and stroke, which are among the leading causes of death in the western world...

BACKGROUND: Coagulation factor XII (FXII) is involved in pathological thrombus formation and is a suggested target of anticoagulants. It is unclear whether FXII levels are correlated with cardiovascular risk factors and whether they are associated with myocardial infarction or ischemic or hemorrhagic stroke. The aim of this study was to investigate the correlation between FXII and cardiovascular risk factors in the general population. We also aimed to study the associations between FXII levels and future myocardial infarction and ischemic and hemorrhagic stroke...
