Subclinical thyroid dysfunction (STD), presenting as subclinical hypothyroidism (SHypo) or subclinical hyperthyroidism (SHyper), defined as abnormal serum thyrotropin (TSH) and normal free thyroid hormones, is associated with increased cardiovascular (CV) risk and mortality. Depending on the degree of such dysfunction, atherosclerosis, coronary artery disease, heart failure and cardiac arrhythmias, predominantly atrial fibrillation, characterize both disorders and increase CV and total mortality compared to euthyroid persons...

BACKGROUND: The incidence of perioperative myocardial infarction is reported to 2-8%. The aim of the study (retrospectively registered) was to evaluate whether control coronary angiography after surgery is useful in case of suspected postoperative myocardial ischemia. METHODS: All patients who demonstrated signs of myocardial ischemia post CABG and underwent coronary angiography from 6/2008 to 06/2015 were retrospectively analyzed. Myocardial ischemia post CABG was defined as an increase of CK/CK-MB, occasionally associated with arrhythmias or low output syndrome...

Hypertension is the single greatest contributor to human disease and mortality affecting over 75 million people in the United States alone. Hypertension is defined according to the American College of Cardiology as systolic blood pressure (SBP) greater than 120 mm Hg and diastolic blood pressure (DBP) above 80 mm Hg measured on two separate occasions. While there are multiple medication classes available for blood pressure control, fewer than 50% of hypertensive patients maintain appropriate control. In fact, 0...

INTRODUCTION: In previous studies we showed that prevalence of myocardial fibrosis as assessed by late enhancement on cardiac MRI in SSc patients is 45% and is associated to diffuse disease (dcSSc) and lower left ventricle ejection fraction; microvascular damage defined as decreased perfusion on cardiac MRI after adenosine infusion, was also very frequent (79%). Our aim was to identify baseline characteristics associated to the development of cardiovascular outcomes (heart failure, coronary artery disease, arrhythmias, vasculopathy, elevated systolic pulmonary artery pressure and death) in SSc patients with previously documented myocardial fibrosis and microvascular damage...

Cardiovascular complications are major contributors to mortality at liver transplantation(LT). However, the impact of coronary artery disease(CAD) on these complications is not well-understood as the literature is limited by non-invasive assessment of CAD, which is suboptimal in patients with cirrhosis. Thus, the current study evaluated cardiovascular events at LT stratified according to presence and severity of CAD quantified on coronary angiography. METHODS: All patients who had LT from January 2010 to January 2017 were evaluated(N=348) but analysis was restricted to patients who had coronary angiography prior to LT(N=283)...

BACKGROUND: Sudden death is the leading cause of mortality in patients with transposition of the great arteries (TGA) and atrial switch surgery. Understanding underlying mechanisms could contribute to identifying high-risk patients and preventing such catastrophic deaths. METHODS: A total of 144 adults (≥18 years) with TGA and atrial switch surgery were followed at our adult congenital center since 1989. Four patients were excluded: two with double-outlet right ventricles and two with subsequent arterial switch surgery in childhood...

Myeloperoxidase (MPO) is a member of the superfamily of heme peroxidases that is mainly expressed in neutrophils and monocytes. MPO-derived reactive species play a key role in neutrophil antimicrobial activity and human defense against various pathogens primarily by participating in phagocytosis. Elevated MPO levels in circulation are associated with inflammation and increased oxidative stress. Multiple lines of evidence suggest an association between MPO and cardiovascular disease (CVD) including coronary artery disease, congestive heart failure, arterial hypertension, pulmonary arterial hypertension, peripheral arterial disease, myocardial ischemia/reperfusion-related injury, stroke, cardiac arrhythmia and venous thrombosis...

Intraventricular conduction abnormalities following cardiac surgery have been thoroughly described, especially after valvular surgery. It is also widely known that several anesthetic factors can cause autonomic disturbances resulting in the unmasking of sinus node dysfunction, significant bradycardia, and cardiovascular collapse during the intraoperative period. However, little is known about asymptomatic episodes, especially those occurring prior to coronary artery bypass grafting (CABG). We report a rare occurrence of an intraventricular conduction defect that presented in an asymptomatic patient following non-ST-elevation myocardial infarction prior to urgent CABG...

Cardio-oncology has emerged as best option for many patients with cardiovascular complications related to cancer and cancer therapy. Classical chemotherapy, targeted and immune therapies as wells as radiotherapy challenge the cardiovascular system at multiple levels, including increased rates of e.g., hypertension, coronary artery disease, cardiomyopathy, arrhythmia, and thrombosis. The cardiologist working within the cardio-oncology team is confronted with a broad spectrum of therapies and combination protocols...

Progress in cancer therapy over the past decades improved long-term survival but increased cancer therapy-related cardiotoxicity. Many novel treatment options have been implemented with yet incompletely characterized cardiovascular side effects including heart failure, coronary artery disease, arrhythmias, valvular disease, venous thromboembolism and myocarditis. Diagnosis of potential cardiotoxic side effects is essential for an optimal treatment but remains challenging. Cardiac biomarkers troponin and brain natriuretic peptide/N-terminal proBNP (BNP/NT-proBNP) have been extensively studied in heart failure and acute coronary syndromes...

Athletic pre-participation screening is essential for minimizing the risk for sudden cardiac death (SCD) in athletes participating in either competitive or leisure sporting activities. The primary causes of SCD in young athletes (<35 years of age) include hypertrophic cardiomyopathy, congenital anomalies of the coronary artery and arrhythmogenic right ventricular cardiomyopathy. Other abnormalities, such as malignant arrhythmia due to blunt trauma to the chest (commotio cordis), myocarditis, valvular disease, aortic rupture (in Marfan syndrome) and ion channelopathies (catecholaminergic polymorphic ventricular tachycardia, Brugada syndrome, long or short QT syndrome), also contribute to a lesser degree to SCD...
