RESUMO

Reactive eosinophilia is associated with inflammatory bowel disease, but its association with eosinophilic myocarditis is rare. We report a case of a 42-year-old man who presented with hypovolemic shock secondary to diarrhea and recently diagnosed nonischemic cardiomyopathy (left ventricular ejection fraction, 0.29). Laboratory evaluation revealed marked peripheral eosinophilia. Cardiac magnetic resonance imaging showed evidence of subacute-to-chronic myocarditis, and endomyocardial biopsy results were consistent with eosinophilic myocarditis. Colonic biopsy specimens revealed ulcerative colitis and no eosinophils. Hematologic evaluation was negative for an alternative cause of eosinophilia. The patient was given corticosteroids; his diarrhea resolved, but there was no short-term improvement in his ejection fraction, so an implantable cardioverter-defibrillator was placed. Follow-up at one year showed that the patient's left ventricular ejection fraction had improved to 0.42.

RESUMO

Degraded by shear stress, loss of high-molecular-weight multimers of von Willebrand factor (VWF) correlates strongly with pressure gradient in aortic stenosis (AS) and obstructive hypertrophic cardiomyopathy (HC). We assessed VWF tests before and after interventions in HC and contrasted the severity of abnormalities in HC to patients with AS, mitral regurgitation, and left ventricular assist devices. Ninety patients with median (interquartile range) age 66 (53 to 72) years, 51% men, with HC had assessments of 3 VWF parameters and B-type natriuretic peptide before and after 26 discreet medical/pacing interventions, 22 alcohol septal ablations, and 28 ventricular septal myectomies. VWF multimers were abnormal in 87% of patients with obstructive HC versus 48% of patients with latent obstruction (p = 0.0001). VWF measurements correlated with peak instantaneous left ventricular outflow tract gradient, Spearman ρ 0.51 to 0.61, p <0.0001. For B-type natriuretic peptide, correlation with left ventricular outflow tract gradient was weaker, ρ = 0.37, p = 0.0005, but stronger with septal thickness or mitral E/e'. In pre-/post-medical treatment of HC, VWF multimers were abnormal in 73%/68% of patients, p = 0.74; pre-/post-septal ablation 74%/26%, p = 0.0035; and pre-/post-septal myectomy 75%/0%, p <0.0001. In obstructive HC, the degree VWF multimer loss was greater than in severe AS or severe mitral regurgitation and overlapped that seen in left ventricular assist devices. In conclusion, VWF activity indexes were predictably abnormal in patients with HC with resting obstruction to a degree where bleeding could be anticipated, accurately reflected gradient changes after intervention, and demonstrated complete normalization after septal myectomy.

RESUMO

BACKGROUND: The panelists of the Joint National Committee recently published new recommendations for the management of hypertension. Our study aims to evaluate how current practice compares. HYPOTHESIS: Current practice likely deviates from the recent JNC 8 panelists' recommendations. METHODS: A survey was sent to cardiology providers at 3 academic medical centers: Mayo Clinic, Jacksonville, Florida; Mayo Clinic, Scottsdale, Arizona; and Mayo Clinic, Rochester, Minnesota. Providers were asked to select which blood-pressure goal would be deemed appropriate in various cases based on individual practice in both the maintenance of patients already on therapy as well as threshold of when to initiate therapy. Comparisons with current recommendations were made, as well as geographic location and level of experience. RESULTS: A total of 251 survey requests were sent (May 2014), and 77 responses (30.7%) were received. Cardiologists tended not to practice according to the new guidelines, with most variation seen in patients age >60 years without comorbidities on active treatment. Providers' selection of initial pharmacologic agents in non-African American patients, African American patients, and patients with diabetes mellitus reflected congruency with guidelines. CONCLUSIONS: Our study found that clinical practice does not correlate well with the new blood-pressure goal recommendations published by the Joint National Committee 8 panelists, particularly in patients age >60 years. Practitioners are likely to follow the recommendations in regard to pharmacologic management.

RESUMO

Absence of an infrarenal inferior vena cava is an infrequent finding on computed tomography scans and is usually an unexpected, incidental finding. This report concerns a young patient with an absent infrarenal inferior vena cava who presented with abdominal and back pain.
