The majority of patients with angina or heart failure have coronary artery disease. Left main bifurcations are particularly susceptible to pathological narrowing. Flow is a major factor of atheroma development, but limitations in imaging technology such as spatio-temporal resolution, signal-to-noise ratio (SNRv), and imaging artefacts prevent in vivo investigations. Computational fluid dynamics (CFD) modelling is a common numerical approach to study flow, but it requires a cautious and rigorous application for meaningful results...

Agustín Ciapponi, Rudolf Pizarro, Jeff Harrison
BACKGROUND: Patients with stable angina not controlled by monotherapy with nitrates, beta blockers, or calcium channel blockers are often treated with combinations of these drugs. There may be adverse effects from, or contraindications to, the use of combinations. In low risk groups, medical treatment appears to be as good an option as percutaneous transluminal coronary angioplasty in terms of averting myocardial infarction, death, or subsequent revascularization. Revascularization procedures are too costly or inaccessible for many patients in developing countries therefore effective and safe medical treatment is needed...

INTRODUCTION AND OBJECTIVES: Estimates of the burden of ischemic heart disease (IHD), including geographic differences, should support health policy decisions. We set out to estimate the burden of IHD in mainland Portugal in 2013 by calculating disability-adjusted life years (DALYs) and to compare this burden between five regions. METHODS: Years of life lost (YLLs) were calculated by multiplying the number of IHD deaths in 2013 (Statistics Portugal) by the life expectancy at the age at which death occurred...

One hundred years have elapsed since Thomas Jonnesco performed the first left cardiac sympathetic denervation (LCSD) in a patient with unmanageable angina pectoris and ventricular tachyarrhythmias, and the progress in the field has surpassed imagination. Here we will review the historic basis of cardiac sympathectomy for the management of life-threatening arrhythmias and will then discuss the often forgotten critical experimental studies that provided the rationale for the amazing growth of its role in clinical management...

Background The instantaneous wave-free ratio (iFR) is an index used to assess the severity of coronary-artery stenosis. The index has been tested against fractional flow reserve (FFR) in small trials, and the two measures have been found to have similar diagnostic accuracy. However, studies of clinical outcomes associated with the use of iFR are lacking. We aimed to evaluate whether iFR is noninferior to FFR with respect to the rate of subsequent major adverse cardiac events. Methods We conducted a multicenter, randomized, controlled, open-label clinical trial using the Swedish Coronary Angiography and Angioplasty Registry for enrollment...

Use of non-ionic contrast media (CM) in coronary arteriography has been reported to cause transient cortical blindness, confusion, amnesia and very rare focal deficits. We report a 69-year old patient with stabile angina pectoris who underwent coronary angioplasty with stent placement due to in-stent thrombosis of the right coronary artery who developed stroke symptoms with radiological suspicion of subarachnoid hemorrhage. No vascular malformations were detected on CT cerebral angiography. Dual antiplatelet treatment was continued...
