The Clinical Course of Idiopathic Dilated Cardiomyopathy

Abstract

These population-based data challenge the clinical perception of the clinical course of idiopathic dilated cardiomyopathy based on referral practice prognostic studies and suggest that the clinical course of this condition may be more favorable than previously recognized.

Impact of Atrial Fibrillation on Outcome of Patients with Idiopathic Dilated Cardiomyopathy: Data from the Heart Muscle Disease Registry of Trieste

“…[28][29][30] The most common initial manifestation is heart failure, which occurs in 75% to 85% of patients. 19,30,31 Some patients affected by IDCM have prevalent rhythm disturbances. Olson et al 32 reported that heritable SCN5A defects are associated with susceptibility to early-onset IDCM and AF.…”

Prognosis and Prognostic Factors in Patients With Idiopathic Dilated Cardiomyopathy in Japan Results From a Nationwide Study

“…Most prior studies of the natural history and prognosis of IDC have been based on populations of selected patients from referral centers, [1][2][3][4][5][6][7][8][9] and therefore, on the basis of different levels of care and management, various prognoses would be expected. The clinical outcome and perception of prognostic factors in IDC is profoundly affected by a bias in patient selection.…”

Comparação do desfecho entre a cardiopatia chagásica e a miocardiopatia dilatada idiopática

“…Two studies have shown a poorer prognosis of patients with Chagas cardiomyopathy in comparison to patients with IDC among several etiologies of heart failureIntroduction Idiopathic Dilated Cardiomyopathy (IDC) has an incidence of 17.9/100,000 inhabitants in the general population 1 . It is the third cause of chronic systolic heart failure 2 , with an annual mortality of 95% in populationbased series and 69% in tertiary referral cohorts 3 .…”
