The hemodynamic effects of flecainide acetate, a new class I antiarrhythmic agent, were studied in 10 patients with coronary heart disease. The drug was injected intravenously at a dose of 2 mg/kg over 30 minutes. The mean drug plasma level achieved was 394 ng/ml (range 329 to 470). The heart rate did not change, but a significant increase (p less than 0.001) in P-R (+17%), QRS (+15%), and Q-T (+7%) duration occurred after drug administration. Negative inotropic effects also were observed and consisted of an increase (p less than 0.01) in pulmonary wedge pressure (+27%) and a decrease (p less than 0.01) in stroke index (-10%), left ventricular stroke work index (-12%), and left ventricular ejection rate (-11%). No significant change in mean aortic pressure or systemic and pulmonary vascular resistance occurred. Left ventriculography performed after drug infusion revealed a significant increase (p less than 0.01) in systolic volume (+9%) and a decrease in ejection fraction (-9%) and mean velocity of circumferential fiber shortening (Vcf) (-13%). A progressive and significant decrease of dP/dt was observed during drug infusion, but 15 minutes after the injection, dP/dt had returned to near basal values. Thus, flecainide acetate has slight, but significant negative inotropic effects, particularly conspicuous during drug infusion. The drug should be administered with caution in patients with poorly compensated heart. [less ▲]

Clonidine or epinephrine are frequently combined to epidural local anesthetics to strengthen sensory block and prolong analgesia. Both drugs impair the hemodynamic profile of central neural blockade but the effects of their combination on arterial pressure and heart rate are not known and were examined in this double-blind prospective randomised study. Forty four patients scheduled for lumbar disc surgery were allocated to two groups. Epidural anesthesia was obtained by administration of 150 micrograms clonidine in 15 ml bupivacaine 0.25% solution without (group C) or with (group C + E) 37.5 micrograms epinephrine. Systolic, mean, diastolic arterial pressure and heart rate were measured throughout the study. Combined epidural and general anesthesia induced a significant decrease in arterial pressure and heart rate in both groups. SAP and MAP decreased significantly less in the patients receiving epinephrine. Low dose epidural epinephrine decreases arterial pressure instability during combined epidural and general anesthesia.

The acute hemodynamic effects of intravenous diltiazem were studied in 8 patients with coronary artery disease, left ventricular (LV) failure (New York Heart Association functional class III), a rest ejection fraction (EF) less than 40% or a cardiac index less than 2.4 liters/min/m2. Hemodynamic measurements and LV angiograms were performed at rest before and after the administration of diltiazem, 0.5 mg/kg, administered at a speed of 5 mg/min. Diltiazem treatment induced a decrease in heart rate from 68 +/- 12 to 55 +/- 9 beats/min (p less than 0.001). Mean aortic pressure decreased from 94 +/- 14 to 81 +/- 15 mmHg (p less than 0.05). Thus, the pressure-rate product significantly decreased under the influence of the drug, from 8,791 +/- 2,465 to 6,342 +/- 1,808 beats mm Hg/min, (p less than 0.001). Diltiazem induced no significant change of LV end-diastolic pressure, pulmonary wedge pressure, cardiac index and LV stroke work index. Systemic vascular resistance decreased (p less than 0.01), whereas pulmonary vascular resistance showed no change. End-systolic volume diminished (p less than 0.02), which accounts for the increase of stroke volume and ejection fraction (p less than 0.001). Disorders of regional contractility were not aggravated by diltiazem, and even improved in individual cases. Thus, intravenous diltiazem may be used safely in patients with heart failure. However, in view of the marked bradycardic effects seen in some cases, heart rate should be carefully monitored. [less ▲]

OBJECTIVE--To characterize the hemodynamic effects of medetomidine (1 mg/m2 of body surface area; dosage, 39 to 46 micrograms/kg of body weight, IM) and midazolam (1 mg/kg of body weight, i.v.) combined with butorphanol (0.1 mg/kg, i.v.), buprenorphine (10 micrograms/kg, i.v.) or saline solution. Reversibility of these effects by atipamezole (2.5 mg/m2; dosage, 97.5 to 115 micrograms/kg, IM) was evaluated. DESIGN--2 treated groups and 1 control group, without repetition. ANIMALS--15 clinically normal dogs (3 groups of 5). PROCEDURE--Medetomidine was administered at time 0; midazolam and butorphanol, buprenorphine, or saline solution at time 20; and atipamezole at time 60. Heart rate, systemic and pulmonary arterial pressures, central venous pressure, body temperature, cardiac output, and arterial and mixed venous blood gas tensions and pH were measured. Cardiac index, stroke index, systemic and pulmonary vascular resistances, and left and right stroke work indexes were calculated. RESULTS--Body temperature, heart rate, cardiac index, and stroke index were significantly decrease below baseline values in some groups. Central venous pressure, pulmonary capillary wedge pressure, and systemic vascular resistance were significantly increased above baseline in all groups. Arterial and venous PO2 and pH decreased in all groups and PCO2 increased, but these changes were more pronounced when buprenorphine was administered. Arterial pressure decreased after atipamezole administration. CONCLUSION--The combinations seemed to result in cardiorespiratory depressant effects of similar importance and most of these effects, which are related to medetomidine, were reversed by atipamezole.

To identify patients at risk of cardiac expansion during hospital stay for a first acute myocardial infarction (AMI), 41 patients underwent right-sided cardiac catheterization soon after admission and serial 2-dimensional echocardiography on days 1, 3 or 4 and between days 7 and 10. Infarct expansion was recognized by echocardiography in 11 patients (27%), most often on the second recording (day 3 or 4). Age, sex, time from onset of pain to catheterization, peak levels of creatine kinase and creatine kinase-MB isoenzyme, heart rate, mean pulmonary artery wedge pressure and left ventricular stroke work index were similar in the 2 groups. Patients in whom infarct expansion developed had a higher incidence of previous systemic hypertension (73% vs 27%, p less than 0.01) and anterior AMI (91% vs 30%, p less than 0.001) and a higher mortality rate at 1 year (73 vs 7%, p less than 0.001) than those who did not. They also had higher systolic (139 +/- 24 vs 126 +/- 18 mm Hg, p less than 0.05) and diastolic (91 +/- 14 vs 75 +/- 13 mm Hg, p less than 0.001) arterial pressures, lower stroke volume index (31 +/- 10 vs 40 +/- 10 ml/m2, p less than 0.01) and much higher systemic vascular resistance (SVR) values (1,713 +/- 380 vs 1,253 +/- 264 dynes s cm-5, p less than 0.0001). In the subgroups of patients with anterior AMI, differences were significant for diastolic arterial pressure, stroke volume index, SVR and mortality.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

The effects of saline (control, group C) and metrenperone (treated, group M) on systemic and pulmonary hemodynamics were determined in conscious 7- to 15-day-old calves after they were intratracheally inoculated with Pasteurella haemolytica. Metrenperone, a specific serotonin (5-hydroxytryptamine) receptor antagonist, was injected intramuscularly (100 micrograms.kg-1) 2 h after the calves were inoculated. Central venous, pulmonary arterial and capillary wedge, and systemic arterial pressures were measured, using fluid-filled catheters. Cardiac output was measured by the thermodilution technique. Heart rate, stroke volume, and pulmonary and systemic vascular resistances were calculated. The parameters were measured hourly from the 1st to the 10th h after inoculation. In group C, cardiovascular response to P. haemolytica inoculation was marked and typically consisted of two systemic hypotensive phases and two pulmonary hypertensive phases. The first phase occurred by the 2nd h post inoculation and was induced by a transient bradycardia and a systemic vasodilation, leading to profound hypotension and reduced venous return. Cardiac performance then transiently recovered, but systemic hypotension persisted. The second hypotensive hypodynamic phase occurred by the 7th h after inoculation, and was associated with a decline in stroke volume, an increase in heart rate, and pulmonary hypertension and vasoconstriction. In group M, the early response to P. haemolytica exposure was similar to that in controls, indicating that, as in sheep, 5-hydroxytryptamine does not contribute to the early hypodynamic response to endotoxemia. In contrast, metrenperone completely abolished late increases in pulmonary arterial pressure and pulmonary vascular resistance, suggesting that 5-hydroxytryptamine contributes to the late pulmonary vasoconstriction. Metrenperone treatment also allowed better restoration of heart rate, and hence, cardiac output was maintained. In conclusion, 5-hydroxytryptamine might have a role in mediating pasteurellic endotoxin induced changes in pulmonary hemodynamics through its type-2 receptors. [less ▲]

Le dosage de l'hémoglobine glyquée est utilisé en pratique quotidienne pour le suivi à long terme de l'équilibre glycémique chez les patients atteints de diabète sucré. De nombreuses techniques ont été décrites depuis une vingtaine d'années, fondées sur différents principes, et dosant différentes formes glyquées de l'hémoglobine. Cela explique que, bien que ce test très informatif soit utilisé au quotidien par les diabétologues, il existe encore une grande disparité des résultats d'un laboratoire à l'autre, rendant leur comparaison impossible.
