Prevalence of mitral valve prolapse in chronic lymphocytic thyroiditis and nongoitrous hypothyroidism.

An increased prevalence of mitral valve prolapse has been found in Graves' disease and a common autoimmune etiology has been suggested for both disorders. We investigated the prevalence of mitral valve prolapse in 87 patients with autoimmune chronic lymphocytic thyroiditis, 50 patients with nongoitrous hypothyroidism and 111 healthy control subjects. Mitral valve prolapse was found in 16.09% of patients with chronic lymphocytic thyroiditis compared to 6 and 5.4% in nongoitrous hypothyroidism and normal controls, respectively. The result is statistically significant, p less than 0.02, and confirms that the prevalence of mitral valve prolapse is significantly increased in patients with autoimmune disorders of the thyroid gland, when compared to normals and nonautoimmune conditions.

Ventricular pacing as the preferable mode for long-term pacing in patients with carotid sinus syncope of the cardioinhibitory type.

This study was designed to determine the efficacy of long-term VVI pacing in patients having the isolated cardioinhibitory type of carotid sinus syncope. The study included 20 patients suffering from repeated syncopal attacks; all were proven by electrophysiological studies to have isolated forms of cardioinhibitory type carotid sinus syncope. Long-term pacing by the VVI mode was carried out in all patients by programming the pacemaker rate well below the patient's sinus rate. The follow-up period after pacemaker implantation, which ranged from 2 to 54 months (average, 20 months), revealed that none of the patients had any recurrence of syncopal attack. Repeated Holter monitoring showed that ten had permanent sinus rhythm without any artificial pacing activity, while in the other ten, pacemaker activity was recorded--predominant in two patients and rare in the other eight. During Holter monitoring, attacks of weakness were reported by four patients; however, they were not related to pacemaker activity. This report indicates the importance of electrophysiological studies in patients suffering from carotid sinus syncope. These studies make possible the diagnosis of the isolated form of cardioinhibitory type syncope for which VVI pacing offers complete relief of symptomatology, thus rendering AV sequential pacing superfluous.

Community phase of cardiac rehabilitation.

Although their effects cannot be shown to statistically alter coronary heart disease mortality or morbidity, voluntary health organizations throughout the world clearly play an important role in bringing about favorable changes in the natural history of this disease and in the community phase of its management. In particular, voluntary organizations are able to conduct research surveys and field trials and by so doing favorably influence state health administration. They are able to correct temporary deficiencies in health services, particularly in the form of psychosocial support and cardiac health education. Observers note that the major change in community phase management has occurred with the wider use of coronary bypass surgery since 1975. More objective data, especially relating to psychosocial factors, can be expected when further research (especially the MONICA Study) is completed. Throughout the world, however, existing voluntary health organizations could be more active in the community phase of cardiac rehabilitation. It would seem an area where such organizations could well do more. A challenging question that should be constantly reviewed is 'Can we do more to reduce the effects of invalidism in cardiac patients?'
