D Panigrahy, P K Sahu
This paper proposes a five-stage based methodology to extract the fetal electrocardiogram (FECG) from the single channel abdominal ECG using differential evolution (DE) algorithm, extended Kalman smoother (EKS) and adaptive neuro fuzzy inference system (ANFIS) framework. The heart rate of the fetus can easily be detected after estimation of the fetal ECG signal. The abdominal ECG signal contains fetal ECG signal, maternal ECG component, and noise. To estimate the fetal ECG signal from the abdominal ECG signal, removal of the noise and the maternal ECG component presented in it is necessary...

Mexico has been positioned as the country with the highest mortality attributed to myocardial infarction among the members of the Organization for Economic Cooperation and Development. This rate responds to multiple factors, including a low rate of reperfusion therapy and the absence of a coordinated system of care. Primary angioplasty is the reperfusion method recommended by the guidelines, but requires multiple conditions that are not reached at all times. Early pharmacological reperfusion of the culprit coronary artery and early coronary angiography (pharmacoinvasive strategy) can be the solution to the logistical problem that primary angioplasty rises...

Gee-Hee Kim, Ho-Joong Youn
Carotid ultrasound is an imaging modality that allows non-invasive assessment of vascular anatomy and function. Carotid intima-media thickness (IMT) has been shown to predict cardiovascular (CV) risk in multiple large studies. However, in 2013, American College of Cardiology/American Heart Association guidelines designated that the carotid IMT as class III evidence level was not recommended for use in clinical practice as a routine measurement of risk assessment for a first atherosclerotic CV event. Following the announcement of this guideline, combined common carotid IMT and plaque, including plaque tissue characterization and plaque burden, using 3D ultrasound was reported to be better than either measurement alone in a variety of studies...

: Aim Echocardiography is the modality of choice for the diagnosis and serial follow-up of aortic arch pathology. In this article, we review the types of obstruction of the aortic arch, various classification schemes of coarctation of the aorta and interrupted aortic arch, methodology for optimal echocardiographic imaging of the aortic arch, and key echocardiographic measurements for accurate diagnosis of obstruction and hypoplasia of the aortic arch. Finally, we will discuss the limitations of echocardiography in optimal imaging of the aortic arch and the use of other non-invasive imaging modalities such as CT or MRI to provide additional information in these cases...

BACKGROUND: Although patients may experience a quick recovery followed by rapid discharge after percutaneous coronary interventions (PCIs), continuity of care from hospital to home can be particularly challenging. Despite this fact, little is known about the experiences of care across the interface between secondary and primary healthcare systems in patients undergoing PCI. AIM: To explore how patients undergoing PCI experience continuity of care between secondary and primary care settings after early discharge...

In modern medicine, lasers are increasingly utilized for treatment of a variety of pathologies as interest in less invasive treatment modalities intensifies. The physics behind lasers allows the same basic principles to be applied to a multitude of tissue types using slight modifications of the system. Multiple laser systems have been studied within each field of medicine. The term "laser" was combined with "surgery," "ablation," "lithotripsy," "cancer treatment," "tumor ablation," "dermatology," "skin rejuvenation," "lipolysis," "cardiology," "atrial fibrillation (AF)," and "epilepsy" during separate searches in the PubMed database...

Martin Mayer
BACKGROUND: The most recent joint guidelines from the American Heart Association (AHA) and American College of Cardiology (ACC) on the management of non-ST-elevation acute coronary syndromes (NSTE-ACS) are a result of a substantial and considered undertaking, and those involved deserve much recognition for their efforts. However, the handling of anticoagulants seems somewhat inadequate, and this is a highly-relevant matter when managing NSTE-ACS. OBJECTIVE OF THE REVIEW: Among areas of potential uncertainty, emergency medicine professionals might still be left wondering about the particulars of anticoagulant therapy when pursuing ischemia-guided management of NSTE-ACS (that is, managing NSTE-ACS without an intent for early invasive measures, such as coronary angiography and revascularization)...

INTRODUCTION: Diagnosing heart failure is often a challenge for the healthcare providers due to it's non-specific and usually subtle physical presentations. The outcomes for treatment are strongly related to the stage of the disease. Considering the importance of early and accurate diagnosis, it is important to have an easy, inexpensive, non-invasive, reliable and reproducible method for diagnosis of heart failure. Recent advancement in radiology and cardiology are supporting the emerging technique of lung ultrasound through B-line evaluation for identifying extravascular lung water...

Non-invasive imaging in the form of single-photon emission-computed tomography (SPECT), positron-emission tomography (PET), computed tomography (CT), echocardiography or magnetic resonance imaging (MRI) is a very useful tool for cardiovascular research as it allows assessment of biological processes in vivo. Nuclear imaging with SPECT and PET offers the advantage of high sensitivity, the potential for serial imaging, and reliable quantification. Currently a wide range of established as well as innovative agents is available and can be imaged with dedicated preclinical and clinical SPECT and PET imaging systems...

In the UK, there are over 80,000 admissions annually with acute coronary syndromes (ACS). Management of ST-elevation myocardial infarction (STEMI) involves primary percutaneous coronary intervention (PCI), which is delivered via dedicated heart attack centres. Non-ST elevation-ACS (NSTE-ACS) accounts for two-thirds of ACS presentations, affecting an older cohort of patients - often with more complex comorbidities. Initial management is with anti-thrombotic therapy with a view to PCI within 24 hours for the most acute cases and within 72 hours for all others...

Transcatheter aortic valve replacement (TAVR) is an effective, nonsurgical treatment option for patients with severe aortic stenosis. The optimal treatment strategy for treating concomitant coronary artery disease (CAD) has not been tested prospectively in a randomized clinical trial. Nevertheless, it is standard practice in the United States to perform coronary angiography and percutaneous coronary intervention for significant CAD at least 1 month before TAVR. All existing clinical trials were designed using this strategy...

Molsidomine is a well-known vasodilatating, antianginal drug. Despite earlier studies with its metabolites (3-morpholino-syndnonimine (SIN-1) and N-nitroso-N-morpholino-amino-acetonitrile (SIN-1A)), which indicated a potential favorable cardioprotective activity, a lot of controversy remains. The aim of our research was to compare molsidomine, SIN-1, SIN-1A, and lidocaine influence on arrhythmias and hemodynamic parameters in 2 experimental models in rats. In the Langendorff heart study, SIN-1A markedly elevated left ventricular systolic pressure, maximum rise and fall of the first pressure derivative, coronary flow, and myocardial oxygen consumption...

CLINICAL INTRODUCTION: A 56-year-old female with adult-onset asthma was admitted to the cardiology service with intermittent left-sided chest pain and progressive dyspnoea. Twelve months prior to this admission, she had received a course of prednisolone for bilateral anterior uveitis. Physical examination was unremarkable with blood sampling revealing a marked eosinophilia (eosinophil count 17.3×10(9)/L) and a perinuclear antineutrophil cytoplasmic antibody staining pattern on indirect immunofluorescence microscopy (myeloperoxidase antibodies 83 IU/mL)...

Refractory angina (RFA) is an unfavourable condition that is characterized with persistent angina due to reversible myocardial ischaemia in patients with coronary artery disease that remains uncontrollable despite an optimal combination of pharmacological agents and revascularization. Despite significant advances in revascularization techniques and agents used in pharmacological therapy, there is a significant population suffering from RFA and the global prevalence is even increasing. Anti- anginal treatment and secondary risk-factor modification are the traditional approaches for this group of patients...

Shear wave elastography (SWE) is a new non-invasive diagnostic imaging technique, that maps the elastic properties of tissues. Nowadays this modality develops increasingly in medicine across its disciplines and opens a new era of high-quality ultrasound examination because it increases the specificity and thus improves diagnostic assurance. This method is similar to manual palpation, shows elastic properties of biological tissues and provides a kind of reconstruction of the internal structure of soft tissues based on measurement of the response of tissue compression...
