RESUMEN
The indications for the use of implantable loop recorders include the evaluation of unexplained palpitations and syncope, embolic stroke of undetermined source, dizziness and lightheadedness presumed to be due to arrhythmogenic etiology, and for atrial fibrillation to guide antiarrhythmic drug therapy or catheter ablation efficacy. Long-term monitoring is especially beneficial if symptoms occur sporadically or are asymptomatic in nature. This is the first case to our knowledge of an acute ST-elevation myocardial infarction which was identified from remote monitoring of an implantable loop recorder through a device clinic.

Cryptogenic stroke (CS) represents one-third of all ischaemic strokes. Studies have shown approximately that half of patients with CS have concomitant patent foramen ovale (PFO), with clear data supporting paradoxical embolization as an aetiology of CS. This article is the first of a multi-part review and will detail the history of PFO closure and the clinical trials that have evaluated the efficacy of PFO device closure. Data favour PFO closure in CS for reducing stroke in appropriate patients and should be considered as a treatment modality.
RESUMEN
PURPOSE: Targeted treatment for pulmonary arterial hypertension (PAH), diagnosed via right heart catheterization (RHC), has been shown to improve morbidity and mortality. Identifying characteristics that predict clinical worsening has been challenging. We sought to evaluate the role of cardiac Magnetic Resonance Imaging (CMR) as a predictor of clinical worsening in a cohort of treatment-naïve pulmonary hypertension (PH) patients. METHODS: We performed a retrospective single center analysis of all adults with newly diagnosed treatment-naïve PH between January 1st 2013 and January 1st 2019. Patients with World Health Organization (WHO)-Group I PAH or WHO-Group II/III PH disease, who underwent both CMR (Signa Horizon 1.5â¯T, General Electric, Milwaukee, WI and Siemens Espree 1.5â¯T, Munich, Germany) and RHC testing prior to targeted PAH treatment, were included for analysis. Cox proportional hazards models were constructed. RESULTS: A total of 38 patients, of which 12 (32 %) experienced the primary outcome of clinical worsening. were included in the final analysis, Patients with clinical worsening were significantly more likely to have RV dysfunction by CMR (including lower RV ejection fraction (HR 0.93, pâ¯=â¯0.007) and more RV dilation (HR 1.02, pâ¯=â¯0.005-0.021)) and RHC (including worse pulmonary vascular resistance (HR 1.32, pâ¯<â¯0.001)), even after adjustment for disease severity. Both CMR and RHC measures of RV dysfunction were found to be equally effective in predicting clinical worsening, regardless of PH etiology. CONCLUSIONS: In treatment-naïve PH patients, including those with WHO-Group II/III disease, both CMR and RHC measures independently and significantly predicted clinical worsening, even after adjustment for disease severity.

In view of hemorrhagic and prothrombotic tendencies, ST-segment elevation myocardial infarction (STEMI) patients with chronic hematologic malignancies (CHM) are felt to be at a higher risk and hence denied standard reperfusion strategies. In-hospital outcomes of CHM patients presenting with STEMI are unclear. The Nationwide Inpatient Sample data files from 2003 to 2014 were used to extract adult patients who presented with a primary diagnosis of STEMI. Patients who had a diagnosis of CHM defined as chronic myelogenous leukemia, chronic lymphocytic leukemia, essential thrombocythemia, polycythemia vera, chronic monocytic leukemia, and multiple myeloma were identified. The primary study outcome measure was in-hospital mortality. Inverse probability weighting-adjusted binary logistic regression was performed to identify independent predictors of in-hospital mortality. Of 2,715,807 STEMI patients included in the final analyses, 11,974 (0.4%) patients had a diagnosis of CHM. Patients with CHM were significantly older, had a higher prevalence of co-morbidities, and had a significantly higher unadjusted in-hospital mortality (14.9% vs 9.0%; p <0.001). After adjusting for co-morbidities, CHM did not independently predict a higher in-hospital mortality (odds ratioâ¯=â¯1.02, 95% confidence intervalâ¯=â¯0.96 to 1.09; pâ¯=â¯0.461). In patients with CHM who presented with STEMI, percutaneous coronary intervention was found to be associated with a significant reduction in in-hospital mortality (odds ratioâ¯=â¯0.22, 95% confidence intervalâ¯=â¯0.18 to 0.27; p <0.001) (c-statisticâ¯=â¯0.81). In conclusion, CHM patients presenting with STEMI should be treated with similar treatment strategies as those without CHM, including revascularization if indicated, as there appears to be a sizable outcome advantage with this approach.

BACKGROUND: Online health information is being used more ubiquitously by the general population. However, this information typically favors only a small percentage of readers, which can result in suboptimal medical outcomes for patients. OBJECTIVE: The readability of online patient education materials regarding the topic of congestive heart failure was assessed through six readability assessment tools. METHODS: The search phrase "congestive heart failure" was employed into the search engine Google. Out of the first 100 websites, only 70 were included attending to compliance with selection and exclusion criteria. These were then assessed through six readability assessment tools. RESULTS: Only 5 out of 70 websites were within the limits of the recommended sixth-grade readability level. The mean readability scores were as follows: the Flesch-Kincaid Grade Level (9.79), Gunning-Fog Score (11.95), Coleman-Liau Index (15.17), Simple Measure of Gobbledygook (SMOG) index (11.39), and the Flesch Reading Ease (48.87). CONCLUSION: Most of the analyzed websites were found to be above the sixth-grade readability level recommendations. Efforts need to be made to better tailor online patient education materials to the general population.
