BACKGROUND: The composition of plaque impacts the results of stenting. The following study evaluated plaque redistribution related to stent implantation using combined near-infrared spectroscopy and intravascular ultrasound (NIRS-IVUS) imaging. METHODS: The present study included 49 patients (mean age 66 ± 11 years, 75% males) presenting with non-ST elevation myocardial infarction (8%), unstable angina (49%) and stable coronary artery disease (43%). The following parameters were analyzed: mean plaque volume (MPV, mm³), plaque burden (PB, %), remodeling index (RI), and maximal lipid core burden index in a 4 mm segment (maxLCBI4mm)...

BACKGROUND: Non-occlusive technique is universally accepted for acquisition of coronary optical coherence tomography (OCT), but the amount of contrast infused is still inconsistently calculated. Proposed herein, is an empirical formula for accurate contrast volume calculation. METHODS: In an observational prospective study, contrast volume of consecutive patients undergoing OCT was either calculated with formula, or eyeballed based on manufacturer recommendations...

BACKGROUND: The study aimed to uncover the regulation mechanisms of diabetic cardiomyopathy (DCM) and provide novel prognostic biomarkers. METHODS: The dataset GSE62203 downloaded from the Gene Expression Omnibus database was utilized in the present study. After pretreatment using the Affy package, differentially expressed genes (DEGs) were identified by the limma package, followed by functional enrichment analysis and protein-protein interaction (PPI) network analysis...

BACKGROUND: Thermal injury during radiofrequency ablation (RFA) of atrial fibrillation (AF) can lead to pulmonary vein stenosis (PVS). It is currently unclear if routine screening for PVS by imaging (ECHO, CT) is clinically meaningful and if there is a correlation between PVS and the electroanatomical mapping system (EAMS) used for the ablation procedure. It was therefore investigated in the current single center experience. METHODS: All patients from January 2004 to December 2016 with the diagnosis of PVS after interventional ablation of AF by radiofrequency were retrospectively analyzed...

BACKGROUND: Mild therapeutic hypothermia (MTH) is a recommended method of treatment for comatose out-of-hospital cardiac arrest (OHCA) survivors. However, the proper site of temperature measurement in MTH is still not defined. The aim of this study was to compare temperature measurements in the esophagus and urinary bladder in comatose post-OHCA patients treated with MTH. METHODS: This temperature comparison protocol was a part of a prospective, observational, multicenter cohort study...

BACKGROUND: Thyroid hormones profoundly influence the cardiovascular system, but the effects of mild thyroid dysfunction on the clinical outcome of acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) are not well defined. This study aimed to determine the effect of mild thyroid dysfunction on 12-month prognosis in ACS patients undergoing PCI. METHODS: In this prospective cohort study with a 12-month follow-up, 1560 individuals were divided into four groups based on thyroid hormone levels upon admission: euthyroidism (used as a reference group), subclinical hypothyroidism, subclinical hyperthyroidism, and low triiodothyronine syndrome (low T3 syndrome)...

BACKGROUND: Aortic valve replacement (AVR) by sutureless prostheses is changing surgeon options, although which patients benefit most, as well as their possible economic impact is still to be defined. METHODS: Perceval-S prosthesis (LivaNova) is reserved, at the documented Institution, for patients at perceived high surgical risk. This retrospective analysis of outcome and resource consumption compared Perceval with other tissue valves. To clarify the comparison, only patients respecting 'instructions-for-use' of Perceval were reviewed...

BACKGROUND: Exercise stress testing (EST) in patients with poor functional capacity measured by time on treadmill is typically deemed inconclusive and usually leads to further downstream testing. The aim of this study was firstly to evaluate the maximum rate pressure product (MRPP) during initial EST to assessthe need for follow-up testing; and secondly to investigate if MRPP is better than age predicted maximum heart rate (APMHR) for diagnostic outcome based on follow up cardiovascular (CV) events in patients with inconclusive EST due to poor functional capacity...

BACKGROUND: Severe familial hypercholesterolemia (FH) individuals, refractory to conventional lipid-lowering medications are at exceptionally high risk of cardiovascular events. The established therapeutic option of last choice is lipoprotein apheresis (LA). Herein, it was sought to investigate the clinical usefulness of LA in a highly selected group of severe heterozygous FH (HeFH), as recently described by the International Atherosclerosis Society (IAS), for their efficacy in lipid reduction and safety...

BACKGROUND: Abdominal aortic aneurysm (AAA) and coronary atherosclerosis share common risk factors. In this study, a single-center management experience of patients with a coexistence of AAA and coronary artery disease (CAD) is presented. METHODS: 271 consecutive patients who underwent elective AAA repair were reviewed. Coronary imaging in 118 patients was considered suitable for exploration of AAA coexistence with CAD. RESULTS: Significant coronary stenosis (> 70%) were found in 65...

BACKGROUND: Red cell distribution width (RDW) in acute heart failure (AHF) is accepted as a prognostic indicator with unclear pathophysiological ties. The aim of this study was to evaluate the prognostic value of RDW in AHF patients in relation to clinical and echocardiographic data. METHODS: 170 patients with AHF were retrospectively studied. All patients had laboratory testing and an echocardiogram performed within 24 h of admission to the Cardiology Department...

BACKGROUND: Sarcoidosis is an increasingly recognized multi-systemic condition. Cardiac sarcoidosis is associated with ventricular arrhythmias and higher mortality rates. Little epidemiological data is available regarding the disease and associated ventricular arrhythmias. METHODS: Data from the National Inpatient Sample (NIS) database 2012-2014, were reviewed. Discharges associated with sarcoidosis were identified as the target population using relevant ICD-9-CM codes...

BACKGROUND: Elevated lipoprotein(a) [Lp(a)] is an independent risk factor for coronary artery disease (CAD). However, its role in real-world practice and implications for clinical care remains limited. Under investigation herein, are the clinical characteristics associated with increased Lp(a) levels in patients presenting with acute coronary syndrome (ACS). METHODS: Lp(a) was measured at admission in patients ≤ 65 years of age presenting with ACS in a single center...

BACKGROUND: There is a paucity of data regarding response of cerebral blood flow to the postural unloading maneuver and its impact on the risk of syncope in patients with aortic stenosis (AS). The aim of the present study was to assess effects of orthostatic stress test on changes in carotid and vertebral artery blood flow and its association with syncope in patients with severe AS. METHODS: 108 patients were enrolled (72 with and 36 patients without syncope) with severe isolated severe AS...

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is a complication of venous thromboembolism (VTE) resulting from non-dissolving thromboembolic in the pulmonary arteries. Previous observations indicate a higher prevalence of atherosclerosis and cardiovascular risk factors in patients with VTE and CTEPH. The purpose of the present study was to evaluate the arterial stiffening assessed by pulse wave velocity (PWV), a marker of arterial stiffness, in CTEPH patients in comparison with a matched control group (CG)...

BACKGROUND: Circulating endothelial cells (CEC) may be used to find new strategies for the early diagnosis of cardiovascular diseases. The major objective of the project is to broaden knowledge of CEC biology by determining their phenotypic characteristics. The additional aim is to clarify whether on the basis of these information it is possible to identify the origin of CEC release (from various cardiovascular compartments). METHODS: Circulating endothelial cells were collected from arterial blood prior to angiography, as well as from arterial and venous blood obtained after angiography/coronary angioplasty, from 18 patients with non-ST-segment elevation myocardial infarction (NSTEMI)...
