Cats Case Study

Decent Essays

Sixty cats were successfully enrolled during 18 months of the study period. Mean age of these cats was 9.0 +/- 4.0 years old with 33 males and 27 females. The breeds of the cats enrolled include Domestic short hair (21), Domestic long hair (14), Maine Coon (12), Ragdoll (4), Scottish Fold (4), Persian (2), Himalayan (2), and Sphynx (1). Twenty-five of 60 cats (41.6%) had a known history of HCM prior to the enrollment in this group. Echocardiographic examination prior to the enrollment confirmed HCM in all enrolled cats with thickened left ventricular walls (interventricular septal wall thickness during diastole: 7.1 +/- 0.4 mm, posterior wall thickness during diastole 6.9 +/- 0.5 mm) and diastolic dysfunction. Thirteen cats of 60 cats …show more content…

The post-hoc analysis compared the mean rank of each genetic type with the mean rank of every other genetic types. Percent inhibition of ADP-Ag in cats with mutated P2RY1 was significantly lower than those with wildtype P2RY1 (P < 0.0001), mutated P2RY12 (P = 0.0036), wildtype P2RY12 (P = 0.0126), and wildtype CYP2C19 genes (P = 0.0009). Percent inhibition of ADP-Ag in cats with wildtype P2RY1 were significantly higher than mutated P2RY12 (P = 0.0406), wildtype P2RY12 (P = 0.0123), and mutated CYP2C19 (P = 0.0061) (Figure 2).
There were also significant differences among groups with different genetic polymorphisms (homozygous, heterozygous and wildtype) in P2RY1, P2RY12, and CYP2C19 genes (P < 0.0001). The post-hoc analysis compared the mean rank of each polymorphism with the mean rank of every other polymorphisms. Percent inhibition of ADP-Ag in cats with homozygous P2RY1 gene was significantly lower than the cats with wildtype P2RY1 (P <0.0001), wildtype P2RY12 (P = 0.0064), heterozygous P2RY12 (P = 0.0176), homozygous P2RY12 (P = 0.004), wildtype CYP2C19 (P = 0.001), and heterozygous CYP2C19 (P = 0.02). Percent inhibition in cats with heterozygous P2RY1 gene was also significantly lower than the cats with wildtype P2RY1 (P (-- removed HTML --) 0.99). The comparisons of the percent inhibition in cats with different polymorphisms in P2RY12 and
