Since the development of the first metallic stents in the mids, there have been continued improvements in stent technology. However, all permanent metallic scaffolds have the inherent limitation of leaving a foreign metallic stent within the vessel. Thus, there has been growing interest in developing bioresorbable scaffolds. We believe that interventional cardiology is at a critical crossroads due to the recent disappointments with the Absorb Abbott Vascular; Santa Clara, CA bioresorbable vascular scaffold BVS , which failed to live up to its promise. Bioresorbable scaffolds are intended do all that drug-eluting stent DES can do; they provide the radial support needed to prevent vessel recoil, seal intimal dissection flaps that may result from balloon angioplasty, and allow for secretion of the anti-proliferative drug. Bioresorbable scaffold systems have the added benefit of completely degrading, which allows for recovery of vessel vasoreactivity and endothelial function. Lactate-based polymer systems provide the majority of data to date for bioresorbable scaffold systems. Poly-L-lactic acid PLLA is a thermoplastic aliphatic polyester that undergoes hydrolysis into shorter lactic acid molecules, which are then converted into water and carbon dioxide via Krebs cycle. Bioresorbable metallic scaffolds are also being pursued and may serve as an alternative to lactate-based polymer systems.

Cardiac imaging plays an important role in the diagnosis of cardiovascular disease CVD. Until now, its role has been limited to visual and quantitative assessment of cardiac structure and function. However, with the advent of big data and machine learning, new opportunities are emerging to build artificial intelligence tools that will directly assist the clinician in the diagnosis of CVDs. This paper presents a thorough review of recent works in this field and provide the reader with a detailed presentation of the machine learning methods that can be further exploited to enable more automated, precise and early diagnosis of most CVDs.

The opinions expressed in this article are not necessarily those of the Editors of the European Heart Journal or of the European Society of Cardiology. Stefan Agewall, John F. Beltrame, Harmony R. The management of acute myocardial infarction AMI 1 has evolved over the past century and particularly in the past 50 years. Important milestones include the development of the electrocardiogram, coronary care units, coronary angiography, reperfusion therapies, and troponin assays.
These innovations are the foundation of contemporary AMI management strategies that include a diagnosis centred on elevated troponin values associated with corroborative clinical evidence, 1 early use of coronary angiography, and reperfusion therapies. Pivotal in the evolution of these contemporary strategies were the early AMI coronary angiography studies undertaken by DeWood et al.
Do these patients differ from those with obstructive CAD? Should they be managed with the same clinical strategies? Do patients with non-obstructive atherosclerosis differ in pathophysiology and outcomes from those with angiographically normal coronary arteries?

Myocardial infarction MI is the most serious manifestation of coronary artery disease and the cause of significant mortality and morbidity worldwide. Galectin-1 GAL-1 , a divalent In conclusion, we show for the first time that GAL-1 level in the left ventricle is increased in early ischemic period. In addition we report for the first time that mouse plasma GAL-1 level is significantly raised as early as 4 hours following MI.

Pathology of Myocardial Infarction. Dr Sampurna Roy MD. Women are remarkably protected against myocardial infarction during reproductive life. This is a section of the subepicardial myocardium from an autopsy case of a 71 year old Asian male. The features are those of acute myocardial infarction showing neutrophilic infiltrate along with areas of necrosis, diffuse interstitial edema and pale myocytes with fading nuclei and decreased striations.
Transmural infarct- This is the infarction of the full thickness of the ventricular wall, usually caused by severe coronary atherosclerosis, worsened by acute plaque disruption and superimposed occlusive thrombosis. Subendothelial infarct- This is limited to the inner one third to one half of the ventricular wall an area of diminished perfusion. Occlusion is typically seen in the proximal 2 cm of the left anterior descending and left circumflex arteries and in the proximal and distal thirds of the right coronary artery.
Vasospasm, platelet aggression or both may cause myocardial infarct without atheroslerosis.

name, gender, date of birth and NHS number), along with the name of the myocardial infarction and tamponade) does not automatically need histology.
A diagnosis of myocardial infarction is created by integrating the history of the presenting illness and physical examination with electrocardiogram findings and cardiac markers blood tests for heart muscle cell damage. At autopsy , a pathologist can diagnose a myocardial infarction based on anatomopathological findings. A chest radiograph and routine blood tests may indicate complications or precipitating causes and are often performed upon arrival to an emergency department.
New regional wall motion abnormalities on an echocardiogram are also suggestive of a myocardial infarction. Echo may be performed in equivocal cases by the on-call cardiologist. According to the WHO criteria as revised in ,  a cardiac troponin rise accompanied by either typical symptoms, pathological Q waves, ST elevation or depression or coronary intervention are diagnostic of MI.
