Flecainide toxicity associated with the use of goji berries: a case report.

Background: Goji berries (GB), usually marketed as a 'superfruit', are a widely used herbal supplement. As with other herbal remedies, the use of GB might be associated with herb-drug interactions, increasing plasma levels of other drugs and causing adverse events. Here, we present the case of a patient that developed flecainide toxicity secondary to an herb-drug interaction, associated with the use of GB to prevent COVID-19.

[Position paper on the results of Symplicity HTN-3 trial. Grupo de estudio de la hipertensión arterial resistente].

Renal artery denervation has shown to be an effective treatment for resistant hypertension. Symplicity HTN 1 and 2 trials showed in small and uncontrolled groups, significant systolic blood pressure reductions down to 30 mm Hg. Symplicity HTN-3, a double blind, randomized, placebo controlled clinical trial shaded this initial enthusiasm.

Effect of physician training on the X-ray dose delivered during coronary angioplasty.

Objective: To assess whether physician training helps decrease the amount of radiation delivered to patients undergoing coronary angioplasty with stent placement.

Background: Coronary angioplasty exposes patients to high doses of ionizing radiation, possibly related to equipment misuse or inappropriate training.

Methods: Reference point air kerma (K(a,r)) and kerma area product (P(KA)) were prospectively registered during a period of 6 months in patients undergoing coronary angiography and angioplasty with stent ad hoc.

[Evaluation of left ventricular function with a 16-slice multidetector tomograph (MDCT-16): correlation with cardiovascular magnetic resonance imaging].

Unlabelled: The evaluation of Left ventricular function has both prognostic as well as therapeutic implications in patients with heart disease. Non-invasive coronary angiography with computed tomography using 16 slices (MDCT-16) allows to obtain images of the coronary anatomy due to its high spatial and temporal resolution, and also, to obtain data regarding Left ventricular function. The objective of this study was to correlate the use of MDCT-16 for the evaluation of the Left ventricular parameters using MRI as the Standard of reference.

[Usefulness of transesophageal dobutamine stress echocardiography in the detection of ischemic cardiopathy].

Objective: To assess the usefulness of transesophageal dobutamine stress echocardiography (TEDSE), to identify patients with coronary artery disease.

Methods: Patients referred for TEDSE with coronary angiography were included. Images were digitized in systolic cine-loop at baseline, with low dose-dobutamine (14.
