Jednalo se o přechodný vzestup krevního tlaku (5% a 10% oproti kontrole – fyziologický roztok) a kontraktilitu myokardu (o 5% a 16% více než fyziologický roztok).
Cardiovascular effects seen in animals (dogs) at exposure levels similar (0.25 mmol/ kg) and higher (1.25 mmol/ kg), respectively, to maximum clinical exposure levels were a dose dependent transient increase in blood pressure (5% and 10%, above saline control) and myocardial contractility (5% and 16%, above saline control).
