Coronary reperfusion and Bezold-Jarisch reflex (bradycardia and hypotension).

This study reports the occurrence of bradycardia and hypotension (Bezold-Jarisch reflex) induced by myocardial reperfusion. Among 92 patients undergoing interventional catheterization for intracoronary thrombolysis in an early phase of acute myocardial infarction, left anterior descending, right coronary, and left circumflex (LC) arteries were identified as the "infarct vessel" in 44, 41, and 7 cases, respectively. The Bezold-Jarisch reflex occurred in 15 of 23 patients (65%) after right coronary recanalization and in 1 of 34 patients after left anterior descending recanalization. The reflex also was observed in 4 (22%) of 18 patients with nonoccluded or nonrecanalized right coronary arteries. The average time from onset of symptoms to right recanalization was significantly shorter (p less than 0.01) among patients in whom the reflex did not develop. Atropine, postural changes, or temporary pacing, or all 3, were generally sufficient to control symptoms. The findings of this study are substantially parallel to those reported by others and confirm that reperfusion of the inferoposterior myocardium is capable of stimulating a cardioinhibitory reflex. Follow-up data available in 15 patients with occluded and recanalized right coronary arteries indicate that the occurrence of the Bezold-Jarisch reflex after reperfusion is not a reliable predictor of myocardial salvage.

Successful removal of papillary endocardial fibroma.

We report a case of systemic embolization secondary to a small papillary endocardial fibroma, a rare cardiac tumor. It was attached to a chords of the mitral valve by a short stalk. The tumor was successfully excised and the mitral valve was preserved. Two-dimensional echocardiography played the major role in the diagnosis of this small endocardial tumor.

A systemic hemodynamic evaluation of indapamide.

The hemodynamic effects of indapamide were evaluated in an open clinical trial of nine patients with mild to moderate hypertension. Hemodynamic and echocardiographic measurements were made before and after six weeks of treatment with single daily doses of 2.5 mg of indapamide. Indapamide significantly reduced the mean standing systolic blood pressure (P less than 0.025), the mean standing diastolic blood pressure (P less than 0.01), the mean arterial blood pressure (P less than 0.001), and the mean total peripheral vascular resistance (P less than 0.01). Cardiac output increased 12% (P less than 0.05) during treatment. The heart rate, left ventricular end-diastolic and end-systolic volumes, systolic volume, and ejection fraction were not markedly altered after treatment with indapamide, although the systolic wall stress index fell slightly. Six weeks of indapamide administration was well tolerated with no notable adverse effects of the drug. The results suggest that indapamide reduces arterial blood pressure in hypertensive patients by decreasing total peripheral resistance.
