:比较卡培肽(α -人心房钠肽)与各种抗心衰药物(强心剂、血管扩张剂和利尿剂)对左冠状动脉前降支扩张结扎引起的充血性心力衰竭(CHF)犬血流动力学和肾功能的影响。卡培肽(0.1-1微克/千克/分钟)剂量依赖性降低升高的左室舒张末期压(LVEDP)。心脏收缩力(LV dP/dtmax)和心率(HR)未见明显变化,但心输出量(CO)在注射卡培肽期间有降低的趋势。硝酸甘油(NG; 3微克/公斤/分钟)和呋塞米(1毫克/公斤)也能降低LVEDP,但效价低于卡培肽。硝普钠(SNP, 10微克/千克/分钟)和多巴酚丁胺(10微克/千克/分钟)导致LVEDP降低,CO增加,HR增加。海氮嗪(H; 100微克/千克/分钟)增加CO,但不降低LVEDP,并诱导HR显著增加。双产物(收缩压× HR)心肌耗氧量指标卡培利肽显著降低,而DB和H显著升高,与NG、SNP、H和DB不同,卡培利肽增加了尿量和尿电解质排泄。这些结果表明,卡培利肽将是治疗CHF的有效药物。
: Effects of carperitide (alpha-human atrial natriuretic peptide) on hemodynamics and renal function in dogs with congestive heart failure (CHF) produced by volume expansion and ligation of the left anterior descending coronary artery were compared with those of various anti-heart failure agents (cardiotonic, vasodilator and diuretic). Carperitide (0.1-1 microgram/kg/min) dose-dependently decreased the elevated left ventricular end-diastolic pressure (LVEDP). No significant changes in cardiac contractility (LV dP/dtmax) and heart rate (HR) were noted, although cardiac output (CO) tended to reduce during the infusion of carperitide. Nitroglycerin (NG; 3 micrograms/kg/min) and furosemide (1 mg/kg) also decreased LVEDP, but the potency was less than that of carperitide. Sodium nitroprusside (SNP; 10 micrograms/kg/min) and dobutamine (10 micrograms/kg/min) caused a reduction in LVEDP and increased CO with an increase in HR. Hydralazine (H; 100 micrograms/kg/min) increased CO without reduction in LVEDP and induced a pronounced increase in HR. Double product (systolic blood pressure x HR), an index of myocardial oxygen consumption, was significantly reduced by carperitide, but significantly increased by DB and H. Carperitide, unlike NG, SNP, H and DB, increased urine volume and urinary electrolyte excretion. These results suggest that carperitide will be an useful therapeutic agent for the treatment of CHF.
