Dosterone program, and sympathetic reflexes [25,49,50,51]. All these information led us to measure BP in all animals all through the study period at Day 0 and then at three, six, 12, and 24 months inside the present study, to be able to assess the cardiovascular security of one of many HS diets commercially offered for cats with lower urinary tract illnesses. No systemic arterial hypertension was identified in any cat all through the 24-month study period. No substantial effect on the diet regime was detected either. The constructive above-mentioned relationship in between salt intake and the slope on the rise in BP with age reported in humans [27] was therefore not identified in these aged cats, which usually do not appear therefore to be sensitive towards the deleterious vascular effects of excess dietary salt intake as observed in elderly people today. These results are in accordance with these reported in this species in short- and medium-term feeding trials, showing that high salt feeding (two.9 to 3.2 g Na/Mcal) will not have an effect on BP in wholesome cats [15,16,19,20]. In addition to its influence on BP, dietary sodium may exert numerous non-blood pressure-related effects, which result in direct target-organ harm, like myocardial hypertrophy and fibrosis as well as alteration of myocardial function, thusTable 3.
