Prognostic value of pulmonary vascular resistance estimated by cardiac magnetic resonance in patients with chronic heart failure.
Pulmonary arterial hypertension is known to be related to worse prognosis in patients with heart failure (HF). Quantification of pulmonary vascular resistance (PVR) still requires invasive right heart catheterization. Recent studies have shown an accurate method for non-invasive estimation of PVR by cardiac magnetic resonance (CMR). Our aim was to evaluate the prognostic value of PVR calculated by CMR in patients with congestive HF.We calculated PVR by CMR in 132 patients [age 65.6 ± 13.1 years, left ventricular ejection fraction (LVEF) 35.1 ± 16.4%, ischaemic aetiology 40%] recently admitted for decompensated HF and derived to our cardiac imaging unit for diagnosis. Patients with cardiac e…
[Diagnostic performance of surface electrocardiogram in early detection of chagasic cardiomyopathy].
Contrast-enhanced cardiac magnetic resonance imaging (CMR) allows early detection of myocardial involvement by Trypanosoma cruzi infection. The aim of our study was to assess the diagnostic performance of the surface electrocardiogram (ECG) in the early detection of Chagas' cardiomyopathy (CCM) compared with CMR.We included 43 asymptomatic patients (30 women, 42 ± 9.8 years), diagnosed of Chagas disease. The sample was divided into 2 groups according to the presence (n=17) or absence (n=26) of electrocardiographic abnormalities. All patients underwent CMR and late gadolinium enhancement (LGE) was used as a marker of early myocardial involvement.Six (14%) patients had a LGE significantly hig…
Cardiac magnetic resonance in the diagnosis of the unusually detected acute myocarditis in the young people: a case report
Myocarditis is among the causes of arrhythmic sudden cardiac death (SCD) in young athletes, with viral infection being the most common cause worldwide. Myocarditis recently has been reported as one of the cardiac complications of coronavirus disease 2019 (COVID-19) in athletes. Here we present a case of a 20-year-old male recreational soccer player with an episode of loss of consciousness in the context of respiratory infection. The patient reports having woken up with symptoms of an upper respiratory tract infection, and after playing a soccer match, he developed dizziness and a headache. He then suffered vasovagal syncope without loss of sphincter control. Physical examination, heart ausc…
Clinical Benefit of Cardiac Resynchronization Therapy With a Defibrillator in Patients With an Ejection Fraction > 35% Estimated by Cardiac Magnetic Resonance
A B S T R A C T Introduction and objectives: Cardiac resynchronization therapy with a defibrillator prolongs survival and improves quality of life in advanced heart failure. Traditionally, patients with ejection fraction > 35 estimated by echocardiography have been excluded. We assessed the prognostic impact of this therapy in a group of patients with severely depressed systolic function as assessed by echocardiography but with an ejection fraction > 35% as assessed by cardiac magnetic resonance. Methods: We analyzed consecutive patients admitted for decompensated heart failure between 2004 and 2011. The patients were in functional class II-IV, with a QRS to 120 ms, ejection fraction 35% es…
Prognostic Value of Pulmonary Vascular Resistance by Magnetic Resonance in Systolic Heart Failure
Abstract Background: Pulmonary hypertension is associated with poor prognosis in heart failure. However, non-invasive diagnosis is still challenging in clinical practice. Objective: We sought to assess the prognostic utility of non-invasive estimation of pulmonary vascular resistances (PVR) by cardiovascular magnetic resonance to predict adverse cardiovascular outcomes in heart failure with reduced ejection fraction (HFrEF). Methods: Prospective registry of patients with left ventricular ejection fraction (LVEF) < 40% and recently admitted for decompensated heart failure during three years. PVRwere calculated based on right ventricular ejection fraction and average velocity of the pulmonary…
