The history of the evolution of the knowledge about the diagnosis and the pathogenetic aspects of heart failure: From the Egyptians to James Mackenzie.

The recognition of the syndrome of heart failure (HF) dates back to the Egyptians, although it is still a mystery how they did that because they had an erroneous notion of the blood flow. Some cardinal aspects of the clinical picture of HF were associated with cardiac disease 1600 years later. Dyspnea was associated with cardiac disease in 1000 CE by Avicenna; pedal edema was associated with cardiac disease by Pawl in 1615. Lower associated dyspnea with pedal edema in 1669, and Bonet associated ascites with cardiac disease in 1679. Lancisi associated the jugular venous distention with right ventricular dilatation in 1728. However, it was only in 1748 that Albertini associated pedal edema and dyspnea with the myocardial disease. The evolution of the understanding that myocardial contractility abnormality was the mechanism behind HF partially started with Lower in 1669, it was clearly pointed out by Albertini in 1748 and refined by Mackenzie in 1908. At that time, it was clear that the exhausted myocardial would lead to the appearance of HF. However, the full understanding of the pathogenesis of HF had to wait for the hemodynamic studies which would appear in the second decade of the 20th century, and for the neurohormonal theory of the 90's.
