Dm1 icd 101/8/2024 ![]() The authors showed that systolic dysfunction was more common in DM1 patients with severe electrocardiographic (ECG) abnormalities (18.8% vs 2.7%, p < 0.01), hypothesizing a physiopathological bidirectional link between LVD and severe ECG abnormalities (rhythm other than sinus PR interval of 240 ms or more QRS duration ≥120 second-degree or third-degree AV block). 1 had a similar mean age and percentage of male patients, lower percentage of atrial arrhythmias (1.8% vs 22.7% vs 12.8% vs 11.4%) and no information about device implantation percentage was provided consequently, we cannot explain the low prevalence of LVD. ![]() 5 recently reported a LVD prevalence of 11.8% in 136 DM1 patients, with an incidence of 2% during a mean follow-up period of 5.76 years.Īccording to previous reports, 2 DM1 patients with LVD were older, were more likely to be male, had longer baseline atrioventricular conduction time interval and intraventricular conduction time duration at study entry, had more incidence of atrial arrhythmias, and were more likely to have undergone device implantation.Ĭompared with other large cohort studies of DM1 patients, 2–5 the study population of Paunic et al. 4 showed a high incidence (12.5%) of LVD in 406 patients with DM1 during a mean follow-up period of 5.7 years. 3 reported a LVD prevalence of 20.6% in 129 patients with DM1 and Groh et al. 2 showed a LVD prevalence of 18.9% in 180 DM1 patients who underwent echocardiographic evaluation Petri et al. In their study population, the authors reported a prevalence of left ventricle systolic dysfunction (LVD) of 6%, much lower than those reported in previous studies. 1 about the echocardiographic findings in a large cohort of Myotonic Dystrophy (DM1) patients. We read with great interest the report of Paunic et al.
