[The development of cardiology in the last 40 years]

In order to correctly appreciate the way cardiology developed in the last 40 years, the "state-of-the-art" balance when the first World Congress took place, September-1950, in Paris, is made. The most current diagnostic methods were relatively scarce at the time-ECG, chest X ray, phonocardiography, pulse wave tracings, coupled with vectorcardiography and ballistocardiography, but in the well equipped hospitals right ventricular catheterization was already performed. The therapeutics of the important morbid situations-like congestive heart failure, arterial hypertension, myocardial infarction and ischemia was disappointing, but closed heart surgery was already taking place. Since then, things had changed suddenly. Over the last 40 years a marked scientific and technology explosion has emerged, that had benefited cardiology science, encompassing several broad areas, namely, patient approaching, pathophysiology understanding, the emergence of new drugs and clinical use, interventional cardiology and remarkable progress in open heart surgery. Imaging techniques development and other technology lead to a simple and accurate cardiac diagnosis. 24 hours ECG and blood pressure recording, and cardiac output measurement, greatly improves our medical knowledge. Computers development, representing the most significant technology advances, has given to cardiology non-predicted advances.(ABSTRACT TRUNCATED AT 250 WORDS)
