To determine whether there was an association between hypertensive retinopathy and high systolic, diastolic, and mean arterial blood pressures in cats.
181 cats.
Systolic, diastolic, and mean arterial blood pressures were measured by use of a noninvasive oscillometric technique. The range of blood pressure measurements in healthy cats from various age groups was determined. Associations among systolic, diastolic, and mean arterial blood pressure; hypertensive retinopathy; hyperthyroidism; left ventricular cardiac hypertrophy; chronic renal failure; and serum biochemical abnormalities were determined.
All blood pressure measurements increased with age in healthy cats. The frequency of hypertensive retinopathy also increased with age and with blood pressure, and hypertensive retinopathy was particularly found in cats with systolic blood pressures > 168 mm Hg. There was an increased risk for hypertensive retinopathy in cats that were female, > 10 years old, and neutered. The risk of chronic renal failure also increased as blood pressure, particularly systolic blood pressure, increased.
Hypertensive retinopathy was common in cats > or = 10 years of age and was associated with systolic blood pressures > 168 mm Hg when measured by the noninvasive oscillometric technique.
确定猫的高血压性视网膜病变与收缩压、舒张压及平均动脉压升高之间是否存在关联。
181只猫。
采用无创示波技术测量收缩压、舒张压及平均动脉压。确定不同年龄组健康猫的血压测量范围。确定收缩压、舒张压及平均动脉压、高血压性视网膜病变、甲状腺功能亢进、左心室心肌肥厚、慢性肾衰竭和血清生化异常之间的关联。
健康猫的所有血压测量值均随年龄增长而升高。高血压性视网膜病变的发生率也随年龄和血压升高而增加，尤其在收缩压>168 mmHg的猫中发现高血压性视网膜病变。雌性、年龄>10岁且已绝育的猫患高血压性视网膜病变的风险增加。慢性肾衰竭的风险也随着血压尤其是收缩压的升高而增加。
采用无创示波技术测量时，高血压性视网膜病变在年龄≥10岁的猫中很常见，且与收缩压>168 mmHg有关。
