Avaliação da pressão arterial sistêmica em cães obesos: comparação entre os métodos oscilométrico e doppler ultrassônico

Abstract

Obesity is the most common nutritional problem in dogs and it can cause various harmful effects on animal health. However, the effect of this condition on systolic blood pressure (SBP) in obese dogs is controversial. The indirect method of measuring PAS is the most commonly used in veterinary medicine for the diagnosis of systemic hypertension, because it is more practical and easy to access. There is little scientific information about the comparison of the two non-invasive methods of measurement of blood pressure in obese dogs. Therefore, the objective of this study was to evaluate the SBP in obese dogs by comparing both indirect methods of measuring blood pressure, with oscillometric and doppler vascular in order to verify the differences in blood pressure values, but also the best method to assess the SBP dogs in this body score condition. The study complain blood pressure measurement of 50 dogs, with were divided in obese dogs with mean body condition score (BCS) of 8.42±0.50 (n=25) and dogs with ideal BCS of 4.56±0.51 (n=25). At comparison of blood pressure values, SBP values obtained by doppler method (152±16mmHg) were higher than the oscillometric (136±11mmHg). Correspondence analysis determined by multivariate statistical analysis showed correlation between body condition and the procedure of the SBP. These findings suggest that the indirect method doppler can better reflect the SBP in obese dogs.INDEX TERMS: Obesity, canine, hypertension, indirect method.

Weight-loss in obese dogs promotes important shifts in fecal microbiota profile to the extent of resembling microbiota of lean dogs

“…In companion animals, a nutritional imbalance has been the most common cause and is mainly related to the prolonged imbalance between caloric intake and energy expenditure, which results in a chronic positive energy balance [9,10]. Excess body weight implies numerous negative effects on health, in addition to being a risk factor for several diseases, such as orthopedic alterations [11][12][13], cardiovascular [14][15][16][17][18], respiratory [19][20][21][22] and metabolic disorders, such as insulin resistance [23] and hyperlipidemia [24,25], immunological disorders [26] and, more recently, obesity has been attributed to causing changes in the intestinal microbiome [27].…”

Evaluation of the nutrients supplied by veterinary diets commercialized in Brazil for obese dogs undergoing a weight loss program

“…Excess body weight has been associated with several diseases, such as orthopaedic (Brown et al., 1996; Kealy et al., 1997, 2000), cardiovascular (Edney & Smith, 1986; Pereira‐Neto et al., 2010, 2014; Piantedosi et al., 2016; Rocha et al., 2007; Tropf et al., 2017), respiratory (Bach et al., 2007; German, 2006; Hendricks, 1992; Pereira‐Neto et al., 2018) and metabolic disorders such as insulin resistance (Brunetto et al., 2011a) and hyperlipidaemia (Brunetto et al., 2011b; Chikamune et al., 1995; Jeusette et al., 2005), as well as immunological disorders (Vendramini et al., 2020). Obesity has been associated with a shorter life span in dogs (Kealy et al., 2002; Salt et al., 2019).…”

“…The consequences of obesity on the health of dogs and cats are widely described in the veterinary literature, and include reduced lifespan [13], as well as orthopedic [14][15][16], cardiovascular [7,[17][18][19][20], respiratory [21][22][23][24] and metabolic disorders, such as insulin resistance [25] and hyperlipidemia [26][27][28].…”
