Abstract

実際の臨床において心機能を評価する場合に必要な基礎的データを得ることを目的として,動物病院に来院した健常犬96頭を用いて心機能影響因子,とくに加齢要因について心エコー検査および血圧測定による検討を加えた。その結果,<BR>1) 左室の収縮能の指標であるFS,EF値に関しては,いずれも4~7歳齢で最高値を示した。<BR>2) 左室の拡張能の指標であるE波およびA波は,加齢に伴ってE波は減少し,逆にA波の流速は増加する傾向が認められた。この傾向はヒトと同様である事から,心臓に対する加齢の影響はヒトとほぼ同様なメカニズムで発現するものと考えられた。<BR>3) 加齢と血圧との関係では,ヒトと同様に年齢を経るにしたがって上昇する傾向が認められた。この変化とヒトにおける変化が同一のメカニズムで発現する可能性があると思われた。

To obtain basic data for estimating influence factors, especially aging factor, on cardiac functions, the echo-cardiographic studies and blood pressure measurements were conducted for 96 healthy dogs which were visiting to the hospital. The results obtained are as follows ;<BR>1) In FS and EF which are systolic factors the peak values were shown between four and seven years old.<BR>2) In the E and A waves which are diastolic factors, the peak velocity of E wave decreased with aging, whereas the A wave-peak velocity tended to increase by aging. These results might be the same as in humans and it seemed that aging effects on the heart were developed by the same mechanisms as in humans.<BR>3) Blood pressure tended to increase with aging, which was also the same as in humans. These findings become usefulness in the diagnosis of hypertension of the dog in the future.
