Medications and treatments are said to have a palliative effect if they relieve symptoms without having a curative effect on the underlying disease such as atherosclerosis or cancer. Some authors speculated that atherosclerotic coronary artery disease (CAD) could be considered a "cancer of the coronary arterial wall". Although the percutaneous coronary intervention (PCI) has proven to be effective in decreasing mortality rates among patients with acute coronary syndromes, the previous meta-analyses of PCI versus optimal medical therapy for stable CAD have not been able to demonstrate a reduction in major adverse cardiac outcomes...

OBJECTIVE: Familial Hypercholesterolemia (FH) is an inherited disorder of lipid metabolism characterized by very high low density lipoprotein (LDL) cholesterol since birth, resulting in premature atherosclerosis and coronary artery disease (CAD). Cascade screening of children and family members of proven FH individuals can identify more subjects who have high LDL cholesterol or the family mutation and appropriate intervention can reduce their risk of atherosclerosis and prevent its complications...

Drug eluting stents (DES) have been increasingly being used for treatment of coronary artery disease (CAD) and have been shown to be very effective in prevention of primary in-stent restenosis (ISR). However DES have been increasingly associated with acute to subacute risk of stent fractures (SF). There is also a paucity of data about different management strategies for SF, especially in the long term. We present a case of recurrent ISR in an area of previous acute SF at the touchdown of saphenous venous graft (SVG) to first diagonal artery (D1)...

BACKGROUND: The development of sensitive myocardial-specific cardiac biomarkers allows for detection of very small amounts of myocardial injury or necrosis. Myocardial injury (MI) as a prelude of the serious perioperative complication myocardial infarction, should be paid more attention, especially in elderly susceptible patients. Myocardial injury after abdominal surgery in elderly patients has not been described yet. The objectives of this study were to identify the incidence, predictors, characteristics and the impact of MI on outcome in elderly patients underwent abdominal surgery...

Coronary artery disease (CAD) remains a significant cause of morbidity and mortality around the world. Patients with stable CAD can have an unpredictable clinical trajectory; thus, additional tools to prognosticate risk in this cohort are warranted. In recent years, a wide range of biomarkers has been recognized for their diagnostic capabilities in patients with stable CAD, identifying those with obstructive disease who may require more intensive preventive therapies or even consideration of percutaneous coronary intervention in some circumstances...

Bone age assessment (BAA) is a commonly performed diagnostic study in pediatric radiology to assess skeletal maturity. The most commonly utilized method for assessment of BAA is the Greulich and Pyle method (Pediatr Radiol 46.9:1269-1274, 2016; Arch Dis Child 81.2:172-173, 1999) atlas. The evaluation of BAA can be a tedious and time-consuming process for the radiologist. As such, several computer-assisted detection/diagnosis (CAD) methods have been proposed for automation of BAA. Classical CAD tools have traditionally relied on hard-coded algorithmic features for BAA which suffer from a variety of drawbacks...

BACKGROUND: Repair of peri-prosthetic proximal tibia fractures is very challenging in patients with a total knee replacement or arthroplasty. The tibial component of the knee implant severely restricts the fixation points of the tibial implant to repair peri-prosthetic fractures. A novel implant has been designed with an extended flange over the anterior of tibial condyle to provide additional points of fixation, overcoming limitations of existing generic locking plates used for proximal tibia fractures...

BACKGROUND: IL-1β-mediated inflammation contributes to development and progression of coronary artery disease (CAD). We aimed to assess the prognostic impact of the inflammatory marker Interleukin-1 receptor antagonist (IL1-Ra), reflecting high IL-1β activity, in patients with documented CAD. METHODS: IL-1Ra levels were determined in 1337 subjects of the AtheroGene study, a prospective cardiovascular registry comprising patients with CAD as detected by coronary angiography presenting with acute coronary syndrome (ACS) or stable angina...

PURPOSE OF REVIEW: Non-adherence to medications for the secondary prevention of myocardial infarction (MI) is a major contributor to morbidity and mortality in these patients. This review describes recent advances in promoting adherence to therapies for coronary artery disease (CAD). RECENT FINDINGS: Two large randomized controlled trials to "incentivize" adherence were somewhat disappointing; neither financial incentives nor "peer pressure" successfully increased rates of adherence in the post-MI population...

Carotid artery disease (CAD) is a common cause of ischemic stroke with high rates of recurrence. Carotid endarterectomy (CEA) or carotid artery stenting (CAS) are highly recommended for the secondary prevention of symptomatic CAD during the first 14 days following the index event of transient ischemic attack or minor stroke. CEA or CAS may also be offered in selected cases with severe asymptomatic stenosis. Herein, we review the utility of neurosonology in the diagnosis and pre-/peri-interventional assessment of CAD patients who undergo carotid revascularization procedures...

Regular physical exercise is responsible for various health benefits, and is recommended for primary and secondary cardiovascular (CV) prevention. Despite these recognized benefits, various clinical events can occur in athletes, including acute myocardial infarction and sudden cardiac death (SCD); the main cause of SCD in veteran athletes is coronary artery disease (CAD). The relationship between intense exercise training and CAD is controversial, and a U-shaped association has been hypothesized. If this is the case, screening for subclinical CAD in older athletes may be justified, and various different methodologies have been proposed...

BACKGROUND: Cervicocephalic artery dissection (CAD) is an important etiology of stroke in the youth. Findings from recent studies suggest it a "group of disease entities" with different underlying etiologies, presentations and prognosis, necessitating an integral study including various types of CAD to get a better understanding of this disease. In addition, Chinese patients with CAD are likely to carry different features from their western counterparts, which remains uncertain yet. Chinese Cervicocephalic Artery Dissection Study (CCADS) therefore aims at exploring the epidemiology, risk factors, clinical/radiological features, diagnosis and prognosis of CAD in Chinese patients...

Catestatin, a catecholamine-release inhibitory peptide, has multiple cardiovascular activities. Conflicting results have been recently reported by increased or decreased plasma levels of catestatin in patients with coronary artery disease (CAD). However, there have been no previous reports regarding the effects of catestatin on arteriosclerosis. This study evaluated the vasoprotective effects of catestatin on human macrophages, human aortic smooth muscle cells (HASMCs) and human umbilical vein endothelial cells (HUVECs) in vitro, and aortic atherosclerosis and wire injury-induced femoral artery neointimal hyperplasia in apolipoprotein E-deficient (ApoE-/-) mice fed with a high-cholesterol diet...

STIM1 and STIM2 are endoplasmic reticulum (ER) membrane proteins that sense decreases in ER-luminal free Ca2+ and, through a conformational change in the STIM cytoplasmic domain, control gating of the plasma membrane Ca2+ channel ORAI1. To determine how STIM1 conveys a signal from the ER lumen to the cytoplasm, we studied the Ca2+-dependent conformational change of engineered STIM1 proteins in isolated ER membranes and, in parallel, physiological activation of these proteins in cells. We find that conserved "sentinel" features of the CC1 region help to prevent activation while Ca2+ is bound to STIM ER-luminal domains...
