Hypertension is a common condition and an important cardiovascular risk factor. SPRINT trial showed that the beneficial effects of targeting systolic blood pressure <120 mmHg were accompanied by more adverse events. De-identified SPRINT database was used for this analysis. All subjects in each group that achieved their respective target blood pressure (<120, intensive; <140, standard) were included. Only readings after reaching target blood pressure for the first time were included. Subjects that never reached target or had <2 readings upon reaching target were excluded...

INTRODUCTION: Platelet activation participate in the development of both coronary artery disease (CAD) and circulating microparticles (MPs). As a commonly used medicine for coronary heart disease, whether aspirin affects the function of MPs remains unclear. AIMS: This study was designed to test MPs from healthy subjects, stable angina (SA) patients before and after aspirin administration were obtained. MPs origins were tested by flow cytometry. Rat thoracic aortas were incubated with MPs (with or without aspirin) to determine the effects of MPs on expression of ERK1/2, JNKs and p38 MAPK...

The development of the promising agent sacubitril/valsartan, known as an angiotensin receptor blocker-neprilysin inhibitor (ARNI), to improve heart failure (HF) management, may benefit morbidity, mortality, and readmission rates in patients with HF. The PARADIGM-HF trial demonstrated that the ARNI can reduce morbidity and mortality in patients with heart failure with reduced ejection fraction (HFrEF), while ongoing PARAMOUNT and PARAGON-HF trials determined whether the ARNI has morbidity and mortality benefits in patients with heart failure with preserved ejection fraction (HFpEF)...

BACKGROUND: Although numerous studies to date have demonstrated a specific phenomenon called the "obesity paradox" in patients after percutaneous coronary intervention (PCI), studies performed in China thus far have consistently shown an absence of this phenomenon. HYPOTHESIS: "Obesity paradox" does exist in Chinese PCI patients. METHODS: 10,724 consecutive Chinese patients who had undergone PCI treatment at a single center from January 2013 to December 2013 were prospectively recruited...

AIM: Non-stent drug delivery platforms have recently emerged as an alternative treatment of peripheral arterial disease. Perfusion catheters have the potential to directly deliver anti-proliferative agents to the medial arterial layer to prevent restenosis. The purpose of this study was to therefore determine the effectiveness of a perfusion catheter to deliver paclitaxel, a proven anti-proliferative agent, to combat restenosis. METHODS: A bench-top model was utilized to determine the varying parameters of a novel occlusion perfusion catheter to maximize paclitaxel delivery using pharmacokinetic evaluation and fluorescent microscopy...

Bariatric surgery has emerged as a promising treatment option for weight loss and to counter the metabolic consequences of obesity. Obesity has been linked to a hyperaggregable state, as well as a blunted response to aspirin. This pilot study assessed the hypothesis that bariatric surgery would lead to an improvement in aspirin-induced platelet inhibition and a reduction in platelet aggregability. METHODS: Fifteen patients scheduled to undergo bariatric surgery were administered two 7-day courses of aspirin 81 mg: the first course administered before surgery and the second was 3 months following surgery...

Low density cholesterol (LDL) has been the prime target of currently available lipid-lowering therapies although current research is expanding the focus beyond LDL lowering and has included high density cholesterol (HDL) also as the target. Bromo and extra-terminal (BET) proteins are implicated in the regulation of transcription of several regulatory genes and regulation of pro-inflammatory pathways. As atherosclerosis is an inflammatory pathway and studies showed that BET inhibition has a role in inhibiting inflammation, the concept of BET inhibition came in the field of atherosclerosis...

Atherosclerosis is a chronic inflammatory disease. Recently, a growing body of evidence emphasizes that the monocyte and macrophage differentiation and activation are key processes in the development of atherosclerosis. However, the regulatory mechanism that manipulates the function of monocyte and macrophage is still unclear. Recent years, epigenetic mechanisms have got a widely attention and bring us a new field of vision. More and more evidence shows that epigenetics weigh highly in atherosclerosis by regulating the function and differentiation states of monocyte and macrophage...
