| الوصف: | Study objective - The aim was to compare the effects of two novel angiotensin converting enzyme (ACE) inhibitors, spirapril and zofenopril, on cardiac remodelling in rats with congestive heart failure after myocardial infarction. Spirapril contains no sulphydryl group, whereas zofenopril is a sulphydryl containing ACE inhibitor. Design - Experimental myocardial infarction was induced by ligation of the left coronary artery. Sham operated animals served as controls. Treatment with spirapril (2-2.5 mg.kg-1.d-1) or zofenopril (12-15 mg.kg-1.d-1) added to the drinking water was started immediately after myocardial infarction or sham operation and continued for six weeks. After the treatment period, all rats were killed. The heart was rapidly removed and perfused as described by Langendorff. Heart rate and left ventricular pressure were measured both at baseline and during stimulation with isoprenaline (6 nM). Heart and lung weights were determined. Subjects - Normotensive male Wistar rats (220-240 g) were used. Measurements and main results - Experimental myocardial infarction considerably increased left ventricular cavity volume. Chronic treatment with either spirapril or zofenopril significantly attenuated this increase in volume. In infarcted rats, the increase in total heart and lung weight was also significantly reduced by chronic treatment with spirapril and zofenopril, indicating that these compounds reduce cardiac mass and pulmonary congestion in congestive heart failure due to myocardial infarction. There were no significant differences between treatment with spirapril and zofenopril. In the isolated and perfused rat heart, myocardial infarction significantly decreased both heart rate and left ventricular pressure. Converting enzyme inhibition only affected heart rate. Heart rate was significantly higher in infarcted animals treated with spirapril and zofenopril than in untreated infarcted animals. Conclusions - Both spirapril and zofenopril attenuated ventricular enlargement and cardiac hypertrophy in rats ... |
