Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
We will include patients with ischemic, non-ischemic dilated cardiomyopathy and hypertrophic cardiomyopathy in sinus rhythm and an echocardiogram, cardiac and cerebral MRI will be performed. Our objective is to quantify the ventricular stasis by post-processing of 2D color Doppler echocardiography and phase contrast-magnetic resonance images in order to establish the relationship between quantifiable intraventricular stasis variables and the prevalence of silent brain infarctions (SBIs) and intracavitary thrombosis determined by magnetic resonance (MRI).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
86 patients ischemic DCM
A cohort of 86 patients with ischemic dilated cardiomyopathy in sinus rhythm and ejection fraction (EF) of LV less than 45%
Doppler echocardiogram exam
A complete echocardiographic study will be performed at enrollment. The echocardiographic images will be acquired as clinically recommended. The protocol will include the acquisition of 1) 2D images in parasternal axis long and short axis; 2) 2D and Doppler tissue images in the apical planes of 4, 2 and 3 chambers; 3) Pulsed, continuous and color Doppler M (DCMM) of transmitral LV flow and LV ejection; 4) 3-Chamber apical plane with and without color Doppler; and 5) 3D LV images. DCMM images will be obtained from the apical window using 4 and 5 chamber planes. Blood flow velocity will be obtained using Color and Gray mode in the 3 chamber view during 5-10 beats in apnea.
Cardiac magnetic resonance
A cardiac MR will be acquired within 10 days after the enrollment. The protocol includes the following sequences: cine mode of short axis from LV base to apex and 2-3-4 chambers. 3D sequence of late enhancement of inversion-recovery. Images will be acquired after 3 min and 10 min of the administration of a total of 0.2 mmol / kg of Prohance®. Intraventricular thrombosis will be monitored. Phase contrast sequences in three orthogonal planes will be acquired. Morphological parameters of LV function (LVEF), contractility ("Wall Motion Score ") and sphericity index will be measured.
Brain magnetic resonance
A brain MR will be acquired within 10 days after the enrollment. Axial, sagittal and coronal spin echo sequence in T1, axial images in diffusion sequences (DWI), enhanced spin echo T2 and FLAIR (fluid-attenuated inversion recovery) sequences shall be obtained. A cerebral infarction will be positive when finding the presence of a focal lesion of\> 3 mm in diameter that meets one of these three characteristics: (1) high signal on isotropic DWI images and low signal on the apparent coefficient map Broadcast (ADC). (2) Cavitary lesion hyperintense on T2, with no signal (or low) in the FLAIR sequence. (3) Hyperintense lesion T2 / T1 hypointense with prior distribution defect known or new in a follow-up study.
Coagulation blood test
5 ml of peripheral blood will be obtained for assessment of prothrombotic markers at enrollment.
Holter monitoring
At inclusion all patients will carry a Holter device for 24 hours to ensure absence of atrial fibrillation
86 patients non ischemic DCM
A cohort of 86 patients with non-ischemic dilated cardiomyopathy in sinus rhythm and ejection fraction (EF) of LV less than 45%
