Overview
Historical Perspective
Discovery
- The first case of hypertrophic cardiomyopathy was described by in 1869 Henri Liouville in the Gazette Medecine Paris. He described a 75-year-old woman who developed worsening dyspnea over several days. On physical examination, she had a systolic heart murmur. She died shortly after the presentation. Liouville H. Rétrécissement cardiaque sous aortique. Gazette Medecine Paris. 1869;24:161–163.
- In 1907 Dr. A. Schmincke, a german pathologist, described two hearts with left ventricular hypertrophy; both came from women in their mid fifties. Schmincke A. Ueber linkseitige muskulose conustenosen. Deutsche Med Wochenschr. 1907;33:2082–2085.
- Levy and von Glahn in 1944, from Colombia University in New York, published a series of cases which resembles HCM. Levy RL, von Glahn WC. Cardiac hypertrophy of unknown cause. A study of the clinical and pathologic features in ten adults. Am Heart J. 1944;28:714–741.
- In 1949, William Evans, a London cardiologist, described familial occurrence of cardiac hypertrophy in a series of patients which were similar to those described in the paper by Levy and von Glahn. [1]
- In 1961 Paré et al. reported thirty members of five generations of a French Canadian family in Quebec in whom the condition was inherited in an autosomal dominant manner.[2]
- In 1958 Teare, an English pathologist, described eight cases of asymmetric cardiac muscle hypertrophy, he thought that they might be benign cardiac tumors. Seven of these caused sudden death in young adults. Teare named the condition “Asymetrical Hypertrophy of the Heart.”[3]
- In 1959 Sir Russell Brock described a young man with angina and a subaortic stenosis and a subaortic intraventricular pressure gradient. He mentioned: “That this is not an isolated case is made clear by the experience of Dr. Glenn Morrow who tells me he has operated on two similar cases in two young men in their early twenties; both survived. He has kindly allowed me to mention these prior to his own report of them (Morrow and Braunwald, Circulation, in press, 1959)." [4]
- Morrow and Braunwald published their first report in the same year, followed by several other reports. [5]
Landmark Events in the Development of Treatment Strategies
- In 1961, Morrow described a surgical procedure to relieve the obstruction,[6] which is still the most widely used method of surgical treatment.
- In 1962, with respect to the observed intensification of obstruction in HCM with the beta-adrenergic agonists,[7] Braunwald suggested the use of newly developed beta-blockers.
- In 1964, Braunwald reported beta-blockers beneficial hemodynamic effects.[8]
- In 1967, the clinical benefits of treatment with betablockers in patients with HCM has been proved to the scientific society. [9][10][11]
