Pet Ownership and the Risk of Arterial Hypertension and Cardiovascular Disease.

Studies show that having pets may reduce the risk of death from any cause, particularly from cardiovascular causes. Furthermore, results of some studies indicate that having pets may reduce the risk of developing hypertension and improve blood pressure control in patients with established hypertension. In addition, there is evidence that having pets may improve the prognosis of patients after myocardial infarction and stroke. One of the most important cardioprotective mechanisms of pet ownership is reduction in activity of the sympathetic nervous system. Pet ownership has a positive effect on the cardiovascular system, likely related to antihypertensive and cardioprotective mechanisms.
