Plain-English summary
A group of 75 cats with high blood pressure (systemic hypertension) underwent heart ultrasound tests to check for heart problems. The results showed that while some cats had normal heart measurements, many had issues like thickening of the heart walls. Specifically, about 39% had thickening of the interventricular septum, and 41% had thickening of the left ventricular wall. However, the wide range of heart changes made it difficult to rely on these tests alone to diagnose hypertension in cats.

Abstract
A retrospective study was performed in 75 hypertensive cats to determine the spectrum and frequency of M-mode echocardiographic abnormalities. Results indicated that 21.3% of the cats had M-mode measurements within normal reference ranges. For cats with echocardiographic abnormalities, changes were variable. Thirty-nine percent of hypertensive cats had hypertrophy of the interventricular septum in diastole, and 41.3% had hypertrophy of the left ventricular (LV) posterior wall in diastole. One cat in five had a dilated left atrium, while fractional shortening and LV internal dimension in diastole were normal in 82.7% and 86.7% of the cats, respectively. The marked variability of echocardiographic findings in hypertensive cats made echocardiography an unreliable screening test for hypertension.
