The field of nuclear cardiology has changed considerably over recent years, with greater attention paid to safety and radiation protection issues. The wider usage of technetium-99m (Tc-99m)-labeled radiopharmaceuticals for single-photon emission computed tomography (SPECT) imaging using gamma cameras has contributed to better quality studies and lower radiation exposure to patients. Increased availability of tracers and scanners for positron emission tomography (PET) will help further improve the quality of studies and quantify myocardial blood flow and myocardial flow reserve, thus enhancing the contribution of non-invasive imaging to the management of coronary artery disease...

Non-invasive imaging plays a critical role in managing patients with cardiovascular disease. Although subjective visual interpretation remains the clinical mainstay, quantitative analysis facilitates objective, evidence-based management, and advances in clinical research. This has driven developments in computing and software tools aimed at achieving fully automated image processing and quantitative analysis. In parallel, machine learning techniques have been used to rapidly integrate large amounts of clinical and quantitative imaging data to provide highly personalized individual patient-based conclusions...

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...

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...

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...

Tushar Kotecha, Roby D Rakhit
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...

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...

Cardiac output (CO) assessment as a basic hemodynamic parameter has been of interest in exercise physiology, cardiology, and anesthesiology. Noninvasive techniques available are technically challenging, and thus difficult to use outside of a clinical or laboratory setting. We propose a novel method of noninvasive CO assessment using a single, upper-arm cuff. The method uses the arterial pressure pulse wave signal acquired from the brachial artery during 20-s intervals of suprasystolic occlusion. This method was evaluated in a cohort of 12 healthy individuals (age, 27...

Physicians and Internists in India have tended to brush under the carpet legal issues affecting their profession. Of concern to all Physicians is the judgment in a recent case where the NCDRC has stated that if MD Medicine Physicians write Physician & Cardiologist on their letterhead it is Quackery. What is MD Medicine degree holder in India qualified and trained to treat ? These are issues which need debate and that can only be initiated once we recognize that there is a problem.

Drug-eluting stents (DES) are the current gold standard for percutaneous treatment of coronary artery disease. However, DES are associated with a non-negligible risk of long-term adverse events related to persistence of foreign material in the coronary artery wall. In addition, DES implantation causes permanent caging of the native vessel, thus impairing normal vasomotricity and the possibility of using non-invasive coronary imaging or preforming subsequent bypass surgery. On the contrary, coronary bioresorbable stents (BRS) may provide temporary mechanical support to coronary wall without compromising the subsequent recovery of normal vascular physiology, and have the potential to prevent late adverse events related to permanent elements...
