Arteriosclerosis or arteriocapillary fibrosis is really a physiologic process naturally accompanying old age, of which it is a part or the cause, and it should be considered a pathologic condition only when it occurs prematurely. It may, however, occur at almost any age after 30, and is beginning to be frequent between 40 and 50.
Not infrequently a heart suffering from fibrosis acts perfectly until some sudden exertion, as lifting, running or serious illness causes it suddenly to become weak. Such a heart rarely regains its former strength. This occurs frequently to those who have supposed themselves to be in perfect physical health.
Healing occurs by a process of "peri-lymphatic fibrosis," but as the natural process of healing may fail at isolated points, nodules of cancer appear, which, although apparently separate from the primary growth, have developed in continuity with it, peri-lymphatic fibrosis having destroyed the cancer chain connecting the nodule with the primary growth.
I am proposing a public-private partnership to advance our arts and humanities and to celebrate the millennium by saving America's treasures great and small. And while we honor the past, let us imagine the future. Now, think about this. The entire store of human knowledge now doubles every five years. In the 1980s, scientists identified the gene causing cystic fibrosis; it took nine years.
In other words, an intestinal or chronic myocarditis or fibrosis develops, with perhaps later a fatty degeneration. When this condition occurs, of course, the repair of the heart is impossible. This form of valvular lesion is the one that is most likely to cause sudden death. In aortic regurgitation Nature causes the heart to beat rapidly.
This is true not only of the circumscribed gumma, but of the condition known as gummatous infiltration or syphilitic cirrhosis, in which the granulation tissue is diffused throughout the connective-tissue framework of such organs as the tongue or liver. Both the gummatous lesions and the fibrosis of tertiary syphilis are directly excited by the spirochætes.
Such irregularity perhaps most frequently occurs with valvular disease, especially mitral stenosis and in the muscular degenerations of senility, as fibrosis. Atropin has been used to differentiate functional heart block from that produced by a lesion. Jour. Med. In the first the heart block is induced by digitalis. This was entirely removed by atropin.

Perhaps generally the term "chronic myocarditis" is incorrect, as a real inflammatory condition is not present and has not been present; it is really a degenerative process with the development of connective tissue, a fibrosis and more or less hardening of the arterioles, a cardiosclerosis. In many instances this fibrosis is associated with fat deposits or fatty degeneration.
If from any cause this hypertension persists, the muscular coats of the arteries will become more or less hypertrophied, and sooner or later degenerative changes begin in the intima, and finally fibrosis occurs in the external coat of the arteries; in other words, arteriosclerosis is in evidence.
