Unusual presentation of listerial myocarditis and the diagnostic value of cardiac magnetic resonance.

Listeria monocytogenes is an infrequent cause of bacterial myocarditis. Myocarditis without evidence of endocarditis is even rarer. Management in such cases involves early diagnosis, antibiotic therapy, and emergency treatment of arrhythmias.

Spontaneous regression of cardiomyopathy in a patient with the acquired immunodeficiency syndrome.

Cardiac involvement is common in patients with the acquired immunodeficiency syndrome (AIDS) and, when symptomatic, it portends a poor prognosis. We present a case of marked spontaneous regression of cardiomyopathy in a patient with AIDS. To our knowledge, this is the first reported case of spontaneous recovery of ventricular function in an AIDS patient.

Hemorrhagic compression of the phrenic nerve after streptokinase infusion.

A 72-year-old woman with acute myocardial infarction underwent intravenous streptokinase therapy following an unsuccessful attempt at right subclavian vein catheterization. Three hours after initiation of therapy, chest radiograph revealed a markedly elevated right hemidiaphragm. Subsequent computed tomography and fluoroscopy of the chest revealed paralysis of the phrenic nerve by hematoma.

Methemoglobin levels following intravenous lidocaine administration.

Methemoglobin levels were obtained before and after administration of IV lidocaine in 40 cardiac patients. Patients were given a 1-mg/kg bolus of IV lidocaine hydrochloride, started on a maintenance infusion at 2.0 mg/min, and given a second bolus of lidocaine of 0.

Comparative hemodynamic and hormonal response of enoximone and dobutamine in severe congestive heart failure.

The peak hemodynamic effect and hormonal response of the phosphodiesterase inhibitor enoximone (MDL 17,043) were compared with those of dobutamine in 10 patients with severe congestive heart failure. Both agents significantly (p less than 0.05) increased cardiac index, stroke volume index and heart rate.

MDL 17,043 therapy in severe congestive heart failure: characterization of the early and late hemodynamic, pharmacokinetic, hormonal and clinical response.

MDL 17,043, an agent with both inotropic and vasodilator properties, was evaluated in the treatment of chronic severe heart failure. The early and late hemodynamic, hormonal, pharmacokinetic and clinical responses to oral MDL 17,043 were studied in 20 patients. MDL 17,043 acutely increased cardiac output from 3.

Plasma vasopressin response to osmotic and hemodynamic stimuli in heart failure.

Arginine vasopressin (AVP) regulation was studied in 42 patients with severe heart failure (CHF) and 10 patients without CHF during cardiac catheterization. Plasma AVP levels were elevated in CHF compared with non-CHF patients (2.98 +/- 2.

Acute hemodynamic effect of oral MDL 17,043 in severe congestive heart failure.

MDL 17,043, when administered intravenously in humans, produces a significant and salutary hemodynamic response. To determine its acute effect when administered orally (3 mg/kg), 10 patients with severe congestive heart failure were studied by right-sided cardiac catheterization for 8 hours. At 4 hours after drug ingestion, there was significant improvement in several hemodynamic measurements.

The acute hemodynamic effects of a new agent, MDL 17,043, in the treatment of congestive heart failure.

MDL 17,043 administered intravenously or orally exerts positive inotropic and vasodilator actions in experimental animal preparations. We studied its acute hemodynamic effects in 15 patients with severe congestive heart failure by right-heart catheterization. Intravenous MDL 17,043 at 10 minutes increased cardiac index (3.
