“…Pese a que la angina de pecho fue reconocida como una entidad clínica en 1768 por William Heberden, pasó más de cien años para que Keefer y Resnick la correlacionen con la isquemia miocárdica (en 1928). 15 En Australia, en 1987 Murphy y Giles 16 fueron los primeros en aplicar la EM para la AP.…”

Introducción: La angina crónica refractaria es definida como el dolor torácico por insuficiencia coronaria que no puede ser controlada por la medicación habitual ni por las técnicas de revascularización, pero sí por la estimulación medular. Material y método: Entre 1999 y 2000 a tres pacientes con edades entre 52 y 62 años y ubicados en las clases III y IV, según la Clasificación Funcional de la New York Heart Association (NYHA-FC), se les sometió a estimulación medular con un electrodo tetrapolar tipo placa colocado en el espacio epidural a nivel de T1, paramediano izquierdo, a través de una minilaminectomía medial; luego, en ese mismo tiempo quirúrgico, se conectó el electrodo a un generador de pulsos programable. Todos habían tenido por lo menos una cirugía de puente aorto coronario. Una de los pacientes era portadora del síndrome X coronario; los otros dos, varones, tenían dolor anginoso severo. Resultados: En un seguimiento a largo a largo plazo se observó una mejoría según la NYHA-FC (de 3,5 a 2,2) y los puntajes de la EVA. No hubo complicaciones y los exámenes clínicos demostraron claramente una mejoría en la calidad de vida y en la realización de actividad física, mejoría del segmento ST en el ECG, disminución significativa de la ingesta de nitratos y reducción en el tiempo y frecuencia de los períodos e internamiento hospitalario. Conclusiones: Aunque pequeño este estudio, demuestra el efecto beneficioso de la EM para la angina crónica refractaria. Este procedimiento es considerado como tratamiento adicional de primera línea para estos pacientes por la European Society of Cardiology y un comité conjunto de la American College of Cardiology y la American Heart Association le asigna un nivel de evidencia Clase IIB.

“…not physically develop spasm. 7 This was further supported in 1940 by Herrman Blumgart's clinicopathological studies, where he reported that atherosclerotic coronary artery disease was responsible for angina in all his autopsy patients. 8 Moreover, he demonstrated the importance of coronary collaterals in patients with occluded vessels without symptoms of angina, as well as coronary thrombosis in those with acute MI.…”

The Evolution of Coronary Artery Spasm: How the Pendulum Has Swung

The concept of coronary artery spasm was described more than 200 years ago; however, during this time the concept has had a troublesome course, with the pendulum of scientific opinion swinging from 'unbelievers', who rationalised it did not exist or played only a minor role in coronary syndromes, to the avid 'believers', who undertook clinical studies supporting its major importance in coronary syndromes (Figure 1). The challenge in identifying the role of coronary artery spasm in coronary syndromes relates to its transient nature and difficulty in imaging its presence during spontaneous episodes. As an iconic clinician scientist, Prof Attilio Maseri demonstrated the importance of coronary artery spasm in the modern era and is considered by many to be the guru of this intriguing pathophysiological condition. In this special edition of the journal, the 'pendulum-swinging' evolution of the coronary artery spasm will be reviewed, with special reference to Maseri's contribution. The importance of understanding the historical perspective of coronary artery spasm is reflected in the words of the American-Spanish philosopher George Santayana: "Those who cannot remember the past are condemned to repeat it." 1 Origins of the Concept of Coronary SpasmThanks to knowledge gained over the centuries, any lay member of the public will tell you that chest pain may arise from the heart. In 1772, William Heberden provided an eloquent description of what he called 'angina pectoris', which is still accurate today and the key symptom for myocardial ischaemia regardless of the underlying cause. 2 In his seminal paper Some Account of a Disorder of the Breast, 2 he writes:"But there is a disorder of the breast marked with strong and peculiar symptoms, considerable for the kind of danger belonging to it, and not extremely rare, which deserves to be mentioned more at length. The seat of it, and sense of strangling, and anxiety with which it is attended, may make it not improperly be called angina pectoris. They who are afflicted with it, are seized while they are walking, (more especially if it be up hill, and soon after eating) with a painful and most disagreeable sensation in the breast, which seems as if it would extinguish life, if it were to increase or continue; but the moment they stand still, all this uneasiness vanishes." The Demand Ischaemia ConceptBy the mid 20th century, the pendulum began to swing in the other direction, with influential clinicians such as Chester Keefer and William Resnik reporting in 1928 that the rigid atherosclerotic lesions surely could

“…More than a century ago, it was first observed that oxygen relieved pain during episodes of angina pectoris [2]. The explanation for this phenomenon came in 1928, when hypoxia of the myocardium was described as the cause of angina [3]. Since then, numerous reports have emphasized the potential benefit of supplemental oxygen in patients with impaired coronary perfusion [4-6].…”

In medical emergencies, supplemental oxygen is often administrated routinely. Most paramedics and physicians believe that high concentrations of oxygen are life-saving [1]. Over the last century, however, a plethora of studies point to possible detrimental effects of hyperoxia induced by supplemental oxygen in a variety of medical emergencies. This viewpoint provides a historical overview and questions the safety of routine high-dose oxygen administration and is based on pathophysiology and (pre)clinical findings in various medical emergencies.
