INTRODUCTION: Amiodarone is often used in the suppression of tachyarrhythmias. One of the more serious adverse effects includes amiodarone pulmonary toxicity (APT). Several pulmonary diseases can manifest including interstitial pneumonitis, organizing pneumonia, acute respiratory distress syndrome, diffuse alveolar hemorrhage, pulmonary nodules or masses, and pleural effusion. Incidence of APT varies from 5-15% and is correlated to dosage, age of the patient, and preexisting lung disease...

Background: The increasing incidence of diabetes mellitus is also reflected in the patient population of a trauma and orthopaedic centre. Diabetics also exhibit more comorbidities than non-diabetics. In addition to surgical problems in these patients, hospitalisation is often accompanied by complications, which can prolong treatment and increase costs. The aim of this retrospective study is to analyse hospitalisation of diabetics compared to non-diabetics, as well as differences in treatment costs, depending on associated age and comorbidities...

BACKGROUND: Recent studies suggested that nonalcoholic fatty liver disease (NAFLD) is associated with an increased prevalence of cardiovascular disease (CVD) in type 1 diabetes. We assessed whether NAFLD also predicts the risk of incident CVD events in type 1 diabetic adults. METHODS: We studied a retrospective cohort of 286 type 1 diabetic outpatients (mean age 43±14years; median duration of diabetes 17 [10-30] years) without secondary causes of chronic liver diseases, who were followed for a mean period of 5...

Heart rate is an established prognostic marker for longevity and is an important contributor in the pathophysiology of various cardiovascular diseases, including ischemic heart disease and heart failure. Most ischemic episodes are triggered by an increase in heart rate, which causes an imbalance between myocardial oxygen delivery and consumption. In addition, increased heart rate is a modifiable risk factor for chronic heart failure. Ivabradine, an inhibitor of If ion channels, is an approved second-line anti-ischemic drug for the treatment of angina...

Stanford Type A aortic dissection is a rapidly progressing disease process that is often fatal without emergent surgical repair. A small proportion of Type A dissections go undiagnosed in the acute phase and are found upon delayed presentation of symptoms or incidentally. These chronic lesions may have a distinct natural history that may have a better prognosis and could potentially be managed differently then those presenting acutely. The method of repair depends on location and extent of the false lumen, as well as involvement of critical structures and branch arteries...

The data presented here support the research article "Association of serum mimecan with angiographic coronary collateralization in patients with stable coronary artery disease and chronic total occlusion" (Shen et al., 2016) [1] where elevated circulating mimecan levels reflected poor angiographic coronary collateralization in such patients. The data included in this article are composed by one figure and consist of (1) validation of serum mimecan measurement by assessing inter- and intra-assay variability in 45 samples; (2) findings on the relation of clinical and angiographic characteristics and biochemical parameters to coronary collateralization in 559 patients; (3) the diagnostic value of serum mimecan for poor collateralization, which was derived from plotting receiver-operating characteristic curves and logistic regression analysis...

BACKGROUND: -A prolonged PR interval is common among cardiac resynchronization therapy (CRT) candidates; however, the association between PR interval and outcomes is unclear, and data are conflicting. METHODS: -We conducted inverse probability weighted (IPW) analyses of 26,451 CRT eligible (EF≤35, QRS≥120ms) patients from the National Cardiovascular Data Registry ICD Registry to assess the association between a prolonged PR interval (≥230ms), receipt of CRT with defibrillator (CRT-D) versus implantable cardioverter defibrillator (ICD), and outcomes...

BACKGROUND: In patients undergoing cardiac surgery, a reduced preoperative left ventricular ejection fraction (LVEF) is common and is associated with a worse outcome. Available outcome data for these patients address specific surgical procedures, mainly coronary artery bypass graft (CABG). Aim of our study was to investigate perioperative outcome of surgery on patients with low pre-operative LVEF undergoing a broad range of cardiac surgical procedures. METHODS: Data from patients with pre-operative LVEF ≤40 % undergoing cardiac surgery at a university hospital were reviewed and analyzed...

BACKGROUND: Patients with coronary artery disease who undergo stent implantation and have concomitant indication for long-term oral anticoagulation represent a considerable proportion of the overall population. To date there is still no consensus about the optimal antithrombotic strategy to choose in this kind of patients, due to the difficult balance between an increased risk of bleeding and thromboembolic complications. Therefore, the aim of this study was to perform a meta-analysis to evaluate the risk and benefits of triple antithrombotic therapy versus dual antithrombotic therapy in patients undergoing coronary stent implantation, requiring long-term oral anticoagulation...

BACKGROUND: Patients at intermediate risk (IR) according to The Society of Thoracic Surgeons risk score are today frequently oriented toward the transfemoral aortic valve replacement (TAVR) option. Our goal was to evaluate the best treatment strategies for IR patients with severe aortic stenosis. METHODS: Of a consecutive series of 1,144 surgical aortic valve replacements (AVRs) performed in our institution between 2008 and 2014, we reviewed the early and late outcomes of two different groups: a low-risk (LR) group of 470 patients, and an IR group of 620...

BACKGROUND: Patients with chronic total occlusions of a coronary artery represent a complex, yet common, clinical conundrum among patients with ischemic heart disease. Chronic total occlusion angioplasty is increasingly being used as a treatment for these complex lesions. There is a compelling need to better quantify the safety, efficacy, benefits, and costs of the procedure. METHODS: To address these gaps in knowledge, we designed the Outcomes, Patient Health Status, and Efficiency IN Chronic Total Occlusion Hybrid Procedures (OPEN CTO) study, an investigator-initiated multicenter, single-arm registry including 12 centers with a planned enrollment of 1000 patients...

BACKGROUND: The predictors of cardiovascular events in patients with chronic refractory angina are limited. High-sensitivity cardiac troponin T (hs-cTnT) assays are biomarkers that may be used to determine the prognosis of patients with stable coronary artery disease. HYPOTHESIS: Hs-cTnT is a predictor of death and nonfatal myocardial infarction (MI) in patients with refractory angina. METHODS: We prospectively enrolled 117 consecutive patients in this study...

: Atherosclerotic renal artery stenosis is an increasingly recognized medical problem especially in elderly patients. It commonly occurs with systemic manifestations including hypertension (HTN), chronic kidney disease (CKD) or atherosclerotic diseases including coronary or peripheral artery disease. Significant renal artery stenosis may result in HTN, ischemic nephropathy, however it is still in debate about the benefit of revascularization. Although several randomized controlled trials including Angioplasty and Stenting for Renal Artery Lesions (ASTRAL) and Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL) study has failed to reveal a significant benefit of angioplasty, angioplasty with medical therapy is increasingly accepted in some patients with certain clinical conditions...

Beginning with the Veterans Administration (VA) Cooperative Hypertension Study of the 1960 s, blood pressure (BP) lowering with antihypertensive medications has been shown to reduce major cardiovascular (CV) outcomes, including coronary heart disease, stroke, heart failure (HF) and CV and all-cause mortality in randomized controlled CV outcome trials. Multiple drugs were usually required in these trials to lower BP in treated participants. Medication regimens in the early trials, including the VA trial, included a thiazide-type diuretic (TTD) as initial therapy...

Younger adults (ages ≤50 years) are increasingly prone to stroke, chronic kidney disease (CKD), and worsening cardiovascular disease (CVD) mortality in the US. An alarming increase in prevalence of high blood pressure (BP) related to the obesity epidemic appears to underlie these adverse trends. However, what specific BP characteristics measured in young adulthood optimally predict incident CVD and CKD later in life remains to be determined. Therefore, an optimization of diagnostic and therapeutic strategies in BP management for young adults is challenging but essential...

Chronic hypertension can result in deleterious effects on various vascular organs including the heart and vessels. Cardiovascular magnetic resonance (CMR) has the unique advantage of the ability to assess ventricular volumes and function, valvular abnormalities, vascular pathology, myocardial perfusion and tissue characterization with high accuracy and reproducibility and also avoid the risk of radiation. As this is the case, CMR seems to be an ideal method for comprehensive assessment of patients with systemic hypertension...

PURPOSE OF REVIEW: The efficacy and safety of β-blockers in the treatment of cardiovascular diseases, such as ischemic heart disease, cardiac arrhythmias, and heart failure, have been well established for decades. In this article, we review the current opinions on the application of β-blockers for secondary prevention in patients undergoing coronary artery bypass grafting (CABG) surgery. RECENT FINDINGS: As the average age of patients treated surgically for coronary artery disease (CAD) is increasing, it is not uncommon to have candidates for CABG presenting with concomitant atrial fibrillation, heart failure or hypertension, most of which were caused by excessive activation of the adrenergic nervous system...

BACKGROUND: The relationship between heart failure (HF) and the serotonergic system has been established in animal studies. However, data on human plasma serotonin level in HF and its significance over the course of the disease is lacking. METHODS: Serotonin levels were measured in 173 patients (108 males, 65 females), 116 were stable HF and 40 were acute decompensated HF patients. The normal control group included 17 healthy volunteers with no known medical or psychiatric conditions...
