Cardiac trauma has been recognized as a complication associated with blunt chest trauma involving coronary artery injury, myocardium contusion and myocardial rupture. Secondary cardiac injuries after trauma supposed to be a critical factor in trauma patients, but the mechanism is not fully explored. Overproduction of TNF-alpha had been reported in multiple trauma animals, this induces oxidative stress resulting in cardiac apoptosis. Apoptosis gradually increases after trauma and reaches to a maximum level in 12 h time...

Subclinical hypothyroidism (SCH) represents a mild or compensated form of primary hypothyroidism. The diagnosis of SCH is controversial, as its symptoms are non-specific and its biochemical diagnosis is arbitrary. The treatment of SCH was examined among non-pregnant adults, pregnant adults and children. In non-pregnant adults, treatment of SCH may prevent its progression to overt hypothyroidism, reduce the occurrence of coronary heart disease, and improve neuropsychiatric and musculoskeletal symptoms associated with hypothyroidism...

BACKGROUND: Acute aortic dissection is a life-threatening cardiovascular emergency. Pentraxin-3 (PTX3) is proposed as a prognostic marker and found to be related to worse clinical outcomes in various cardiovascular diseases. This study sought to investigate the association of circulating PTX3 levels with in-hospital mortality in patients with acute Type A aortic dissection (TAAD). METHODS: A total of 98 patients with TAAD between January 2012 and December 2015 were enrolled in this study...

BACKGROUND: Despite its severity, coronary artery ectasia (CAE) is still poorly understood. High-sensitivity C-reactive protein (hs-CRP) has been recognized as a prognostic factor in some cardiovascular diseases but not assessed in CAE. The aim of this observational study was to investigate the prognostic value of hs-CRP in CAE. METHODS: Our analysis evaluated the effect of the baseline hs-CRP on cardiovascular events (CVs) (cardiac death and nonfetal myocardial infarction) in consecutively enrolled stable CAE patients...

Despite significant advances in treatment of coronary artery disease and improvements in interventional devices and techniques, the subset of obstructive calcified coronary artery disease remains challenging to treat. Percutaneous treatment of these lesions results in increased rates of procedural complications, as well as a higher risk of stent underexpansion and malapposition. This is associated with higher rates of restenosis, target lesion revascularization (TLR), and major adverse cardiac events (MACE)...

BACKGROUND: We hypothesized that the additional administration of eicosapentaenoic acid (EPA) in patients with stable coronary artery disease (CAD) receiving statin has the potential to lower the serum pentraxin 3 (PTX3) level, an indicator of plaque stabilization. METHODS: We randomly assigned CAD patients already receiving statin therapy to an EPA group (1800 mg/day, n = 53) or control group (n = 53). RESULTS: No significant difference was found in the change in the plasma PTX3 level between the groups...

Unilateral spinal anesthesia is a cost-effective and rapidly performed anesthetic technique. An exclusively unilateral block only affects the sensory, motor and sympathetic functions on one side of the body and offers the advantages of a spinal block without the typical adverse side effects seen with a bilateral block. The lack of hypotension, in particular, makes unilateral spinal anesthesia suitable for patients with cardiovascular risk factors e. g. aortic valve stenosis or coronary artery disease. Increasing numbers of surgical procedures are now being performed on an outpatient basis...

BACKGROUND: The lipoprotein scavenger receptor BI (SCARB1) rs10846744 noncoding variant is significantly associated with atherosclerotic disease independently of traditional cardiovascular risk factors. We identified a potentially novel connection between rs10846744, the immune checkpoint inhibitor lymphocyte activation gene 3 (LAG3), and atherosclerosis. METHODS: In vitro approaches included flow cytometry, lipid raft isolation, phosphosignaling, cytokine measurements, and overexpressing and silencing LAG3 protein...

Aim. Diabetes mellitus (DM) is a major risk factor for cardiovascular disease. The implications of a diagnosis of DM are as severe as the diagnosis of coronary artery disease. For many patients with complex coronary artery disease, optimal revascularization strategy selection and optimal medical therapy are equally important. In this study, we compared the hemodynamic results of different stenting techniques for Medina 0,1,0 left main bifurcation lesions. Methods. We use idealized left main bifurcation models and computational fluid dynamics analysis to evaluate hemodynamic parameters which are known to affect the risk of restenosis and thrombosis at stented bifurcation...

BACKGROUND: Despite the importance of identifying and screening dyslipidemia to prevent coronary artery diseases CAD(Coronary Artery Disease), little information is available on dyslipidemia in our large area. So the present study aimed to assess the management status of lipid abnormalities and its association with other CAD risk factors in an urban population of southeast of Iran. METHODS: This cross-sectional study was a part of the Kerman coronary artery disease risk factor study KERCADRS (Kerman coronary artery disease risk study) as a population-based, epidemiological research among 5900 individuals aged 15 to 75 years who were residents of Kerman city, the largest city in Southeast of Iran...

Spontaneous coronary artery vasospasm is one of the important causes of acute chest pain syndromes. The diagnosis of diffuse multifocal spasm can be quite challenging and it could be easily mistaken for diffuse coronary artery disease. The use of intracoronary nitroglycerin can relieve spasm and reveal the real extent of coronary artery disease. Herein we present a case presenting with acute myocardial infarction due to severe coronary artery spasm that had even received fibrinolytic therapy. Multiple narrowing was shown during coronary angiography and the patient was scheduled for percutaneous coronary intervention (PCI)...

The management of concomitant obstructive coronary artery disease and severe aortic stenosis in poor surgical candidates is an evolving topic. Although the typical current practice is to perform percutaneous revascularization before transcatheter aortic valve replacement (TAVR), some data have emerged regarding revascularization after performing TAVR. We present the case of a 90-year-old man with multivessel coronary artery disease who was at prohibitive risk for surgical aortic valve replacement. We first performed TAVR with use of hemodynamic support, then Impella-assisted multivessel percutaneous coronary intervention on the patient's unprotected left main coronary artery...

BACKGROUND: The prognostic effect of multi-component cardiac rehabilitation (CR) in the modern era of statins and acute revascularisation remains controversial. Focusing on actual clinical practice, the aim was to evaluate the effect of CR on total mortality and other clinical endpoints after an acute coronary event. DESIGN: Structured review and meta-analysis. METHODS: Randomised controlled trials (RCTs), retrospective controlled cohort studies (rCCSs) and prospective controlled cohort studies (pCCSs) evaluating patients after acute coronary syndrome (ACS), coronary artery bypass grafting (CABG) or mixed populations with coronary artery disease (CAD) were included, provided the index event was in 1995 or later...

BACKGROUND: Cardiogenic shock after acute myocardial infarction is an indication for emergent coronary artery bypass grafting in patients not amenable to percutaneous coronary intervention. Our study aimed to evaluate and identify risk factors for early and long-term outcomes in such patients. METHODS: A total of 508 patients who underwent coronary artery bypass grafting for cardiogenic shock complicating acute myocardial infarction between January 2000 and June 2014 were divided into 3 time cohorts: 2000 to 2004 (n=204), 2005 to 2009 (n=166), and 2010 to 2014 (n=138)...

BACKGROUND: -A continuous relationship between reductions in low-density lipoprotein cholesterol (LDL-C) and major adverse cardiovascular events (MACE) has been observed in statin and ezetimibe outcomes trials, down to achieved levels of 54 mg/dL. However, it is uncertain whether this relationship extends to LDL-C levels <50 mg/dL. We assessed the relationship between additional LDL-C, non-high-density lipoprotein cholesterol (non-HDL-C), and apolipoprotein B100 (apoB) reductions and MACE among patients within the ODYSSEY trials that compared alirocumab versus controls (placebo/ezetimibe), mainly as add on to maximally tolerated statin...

OBJECTIVE: Known risk factors do not fully explain the comparatively high susceptibility to coronary heart disease (CHD) in South Asians (Indian, Pakistani, Bangladeshi, and Sri Lankan populations in South Asia and overseas). The search for explanatory hypotheses and cofactors that raise susceptibility of South Asians to CHD continues. The aim of this study was to propose "the high-heat food preparation hypothesis," where neo-formed contaminants (NFCs) such as trans-fatty acids (TFAs) and advanced glycation end-products (AGEs) are the cofactors...
